Background: This longitudinal study assessed the prospective link between childhood maltreatment and sleep quality in adulthood, with a specific focus on examining whether different coping style tendencies influence these associations., Methods: The baseline sample included 1600 adult participants, with 1140 participants successfully followed up 5 years later. The key variables were measured using the Childhood Trauma Questionnaire (CTQ), Simplified Coping Style Questionnaire (SCSQ), and Pittsburgh Sleep Quality Index (PSQI). Generalized linear mixed models were employed to estimate unstandardized β estimates and 95 % confidence intervals (95%CIs). Structural equation modeling was used to test the mediation model., Results: Individuals reported childhood maltreatment at baseline were at an increased risk for sleep disturbances at follow-up. Childhood maltreatment negatively predicted the baseline coping style tendency (β = -0.29, P < 0.001), the baseline coping style tendencies negatively predicted the follow-up sleep quality (β = -0.10, P < 0.001), and childhood maltreatment positively predicted the follow-up sleep quality (β = 0.42, P < 0.01). The mediating effect of baseline coping style tendencies between childhood maltreatment and the follow-up sleep quality was significant, with an effect value of 0.03., Limitations: First, the sample was from a single province (Shandong), which limits the generalizability of the findings. Second, recall bias was unavoidable in this adult sample study., Conclusions: Developing positive coping strategies is an important way to reduce the risk of sleep problems in adults with a history of childhood maltreatment., Competing Interests: Declaration of competing interest All authors declare that they have no conflicts of interest., (Copyright © 2024 The Authors.

Background: Childhood trauma, including emotional neglect, emotional abuse, physical abuse, and sexual abuse, may contribute to borderline personality features like affective instability, identity problems, negative relationships, and self-harm. This study aims to explore how different types of childhood trauma affect these features in bipolar versus unipolar depressive disorders., Methods: We included 839 participants of the Netherlands Study of Depression and Anxiety (NESDA) with a lifetime diagnosis of major depressive disorder single episode (MDDS; N = 443), recurrent major depressive disorder (MDD-R; N = 331), or bipolar disorder (BD; N = 65). Multivariate regression was used to analyze data from the Childhood Trauma Interview and borderline features (from the self-report Personality Assessment Inventory)., Results: On average, participants were 48.6 years old (SD: 12.6), with 69.2 % being women, and 50.3 % of participants assessed positive for childhood trauma. Adjusted analyses revealed that participants diagnosed with BD, followed by MDD-R, exhibited the highest number of borderline personality features. Additionally, within the entire group, a strong association was found between childhood trauma, especially emotional neglect, and the presence of borderline personality features., Conclusion: Given the high prevalence of childhood trauma and borderline personality features, screening for these factors in individuals with mood disorders is crucial. Identifying these elements can inform and enhance the management of the often fluctuating and complex nature of these comorbid conditions, leading to more effective and tailored treatment strategies., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024 The Authors.

Background: Stressors across the lifespan are associated with the onset of major depressive disorder (MDD) and increased severity of depressive symptoms. However, it is unclear how lifetime stressors are related to specific MDD subtypes. The present study aims to examine the relationships between MDD subtypes and stressors experienced across the lifespan while considering potential confounders., Methods: Data analyzed were from the Zone d'Épidémiologie Psychiatrique du Sud-Ouest de Montréal ( N = 1351). Lifetime stressors included childhood maltreatment, child-parent bonding, and stressful life events. Person-centered analyses were used to identify the clusters/profiles of the studied variables and multinomial logistic regression analyses were performed to examine the relationships between stressors and identified MDD subtypes. Intersectional analysis was applied to further examine how distal stressors interact with proximal stressors to impact the development of MDD subtypes., Results: There was a significant association between proximal stressors and melancholic depression, whereas severe atypical depression and moderate depression were only associated with some domains of stressful life events. Additionally, those with severe atypical depression and melancholic depression were more likely to be exposed to distal stressors such as childhood maltreatment. The combinations of distal and proximal stressors predicted a greater risk of all MDD subtypes except for moderate atypical depression., Conclusions: MDD was characterized into four subtypes based on depressive symptoms and severity. Different stressor profiles were linked with various MDD subtypes. More specific interventions and clinical management are called to provide precision treatment for MDD patients with unique stressor profiles and MDD subtypes.

Background: Childhood abuse and neglect pose important risk factors for the development of psychopathology during pregnancy. However, only a few studies have assessed the effects of a specific type of abuse during the perinatal period, namely, psychological maltreatment, which includes emotional abuse and neglect. These studies have found that women who have experienced psychological maltreatment exhibit higher levels of antenatal depressive symptoms and greater difficulties forming attachment with their babies than women who have not experienced this kind of adversity. The aim of this study was to examine how emotional abuse and neglect experiences may favor the occurrence of psychological distress in pregnant women, and whether prenatal attachment might explain this association., Methods: Participants comprised 128 Italian pregnant women ranging in age from 21 to 46 years (M age  = 33.4; SD = 6.10). Women responded to the following self-report instruments: CECA.Q and CTQ-SF, for the assessment of psychological maltreatment experiences; MAAS, for the evaluation of prenatal attachment; and PAMA, for the assessment of perinatal psychological distress., Results: Pearson correlations revealed a positive association between childhood neglect and perinatal psychological distress and a negative association between childhood neglect and prenatal attachment scores. No significant correlations were found for emotional abuse. Perinatal psychological distress was negatively associated with prenatal attachment. Mediation analyses showed significant associations between childhood neglect and the dimensions of perinatal affectivity and prenatal maternal attachment. Prenatal maternal attachment mediated the relationship between neglect and perinatal psychological distress., Conclusions: The transition to motherhood is a sensitive period, particularly for women who have experienced abuse and neglect during childhood. These experiences may negatively impact a woman's disposition to emotionally and behaviorally engage in the formation of a bond with their unborn baby. These results may have important prevention and clinical implications and thus warrant further exploration., (© 2024. The Author(s).)

Since the 1990s, cases of serious violence and abuse, particularly sexual abuse in educational and social institutions of the Catholic Church, have been reported in numerous countries, including Ireland, the United States, and Australia. In many countries, commissions have been set up to investigate the widespread cases of abuse that could not be prosecuted under criminal law. The testimonies of survivors and other witnesses are used by the commissions of inquiry in their work. Since 2016 the Independent Inquiry into Child Sexual Abuse in Germany has collected more than 2,500 reports from survivors of child sexual abuse. Forty-four testimonies were analyzed in a study seeking to understand more about lifetime abuse. In an explorative analysis, aspects of time as a key category in the reports were identified using the structured content analysis method. The results highlight the importance of time in the reports and during all phases of the survivors' lives. Overall, four themes are relevant: (a) the identification of turning points, (b) time to make sense of what happened, (c) the practice of waiting, and (d) time-bound experiences of testifying., Competing Interests: Declaration of Conflicting InterestsThe author declared no potential conflicts of interests with respect to the authorship and/or publication of this article.

Existing research suggests that prior victimizations during a person's lifetime, particularly childhood traumas and maltreatment, are risk factors for abuse and revictimization in adulthood, although longitudinal evidence is sparse. Using data from a 30-year ongoing longitudinal study of the long-term consequences of childhood maltreatment, this paper describes the extent to which childhood maltreatment predicts subsequent victimization and partner violence victimization at two time points in adulthood. Data were obtained from a prospective cohort design study in which children with court-substantiated cases of maltreatment (ages 0-11 years) and demographically matched controls were followed into adulthood and interviewed over several waves. Childhood maltreatment was assessed through juvenile and adult court records from 1967 to 1971 in a midwestern county area in the United States. Victimization experiences were assessed from 2000 to 2002 ( M age  = 39.5 years) and 2009 to 2010 ( M age  = 47.5) and included two types based on information from the lifetime trauma and victimization history instrument and questions about past year partner violence victimization. Individuals with histories of childhood maltreatment were more likely to report physical and sexual assaults and kidnapping and stalking victimization than controls through age 39.5. In contrast, the two groups did not differ at the later assessment at age 47.5, except maltreated individuals reported greater risk for sexual assault/abuse than controls. For intimate partner violence victimization at age 39.5, maltreated and control groups differed only in terms of victimization involving injury. Later in adulthood, more individuals with histories of childhood maltreatment reported partner physical violence victimization compared to controls. Although these longitudinal findings showed a general decline in victimization experiences over the two time points, these results demonstrate that childhood maltreatment increases risk for subsequent revictimization in middle adulthood, specifically for sexual assault/abuse and intimate partner physical violence victimization. These findings have implications for prevention and intervention efforts targeting maltreated children., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interests with respect to the authorship and/or publication of this article.

Background: Childhood Maltreatment (CM) is linked to adverse outcomes, including Borderline Personality Disorder (BPD) and increased propensity for offending behaviors. However, research on the specific role that BPD plays between the two is limited and highly relevant given the high prevalence of CM in Australia., Objective: The present study aimed to investigate (1) the relationship between CM and subsequent offending behaviors, (2) whether BPD mediates the relation between CM and offending behaviors, and (3) which type of CM (physical, sexual, emotional abuse, neglect, exposure to domestic violence, multitype maltreatment) predicts BPD., Participants: The sample comprised 106 self-identified Australian female survivors of interpersonal violent crimes., Methods: Participants completed an online survey consisting of the Adverse Childhood Events Questionnaire, the McLean Screening Instrument for BPD, and a self-created questionnaire to measure offending behaviors. Regression, mediation analysis, and logistic regression were conducted., Results: CM significantly predicted offending behaviors (path c, B = 1.39, p <. 001) with BPD partially mediating the relationship (path c', B = 1.04, 95 % CI [0.31, 1.77], p = .006; path a, B = 0.47, 95 % CI [0.12, 0.83], p = .009, path b, B = 0.34, 95 % CI [0.07, 0.61], p = .014). Emotional abuse and multitype exposure were identified as predictors of BPD symptom development (OR = 9.42, 95 % CI OR [2.58, 34.40]; OR = 3.81, 95 % CI OR [1.41; 10.28], respectively)., Conclusion: These findings indicate the necessity of early interventions addressing CM, with a particular focus on emotional abuse and exposure to more than one type of maltreatment, to reduce the risk of developing BPD symptomatology and mitigate future offending behaviors., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2024 The Authors.

Findings have revealed a strong link between exposure to child maltreatment (CM) and later chronic pain. Concurrently, other findings have been grounded in the understanding that CM consequences may not end with the exposed individual, rather, they extend to their offspring. However, little is known regarding the possible intergenerational transmission of chronic pain following CM. This study examines whether chronic pain among parents and their young adult offspring may be associated with parental exposure to CM. Three hundred ninety-three parent-offspring dyads (parents' mean age = 58, SD = 5.91 years; offspring's mean age = 27, SD = 3.91 years) completed self-report questionnaires, assessing CM (CTQ), posttraumatic stress (PTS) and disturbances in self-organisation (DSO) symptoms (ITQ), and chronic pain. CM was associated with chronic pain mediated by DSO symptoms among parents (indirect effect = 0.77; p = 0.007) and PTS symptoms among offspring (indirect effect = 0.285; p = 0.005). Offspring chronic pain was significantly associated with parental CM through two intergenerational paths: the mediation of parents' DSO symptoms and chronic pain (indirect effect = 0.298; p = 0.011), and through parents' PTS symptoms and offspring's PTS symptoms (indirect effect = 0.077; p = 0.004). This study's findings support the relevance of the intergenerational transmission of chronic pain following parental exposure to CM. Furthermore, the findings reveal complex PTS symptoms as a possible underlying mechanism for the intergenerational associations of chronic pain following CM., (© 2024 John Wiley & Sons Ltd.)

Adult survivors of childhood sexual abuse (CSA) may experience emotional, social, and psychological difficulties, heightened due to the interpersonal nature of harm. Despite the demonstrated effectiveness of trauma-focused treatments in the West, a culturally specific understanding of the needs of and treatments for survivors in South Asia is still in its infancy. The study aimed to systematically review research findings on the mental health impacts of CSA on adult survivors and current treatment approaches and their efficacy and acceptability in South Asia. Seven databases (Scopus, Ovid, CINAHL, ProQuest, EThOS, Google Scholar, and Dogpile) and five peer-reviewed South Asian journals were searched from inception until March 30, 2023. Searches included participants who were adult survivors of CSA of South Asian origin residing in South Asia. Studies on their mental health, different treatments, and the efficacy and acceptability of these treatments were included. Quality assessment tools were used to appraise the quality of included studies. The results were synthesized narratively. A total of 3,362 records were retrieved, and 24 articles were included in the final review. Twenty studies reported mental health impacts of CSA on adult survivors, four studies reported current treatments offered, and two studies were on recovery. However, no study focused on the efficacy or acceptability of the treatments being delivered. Even though the needs of adult CSA survivors in South Asia have been partly identified, there is very little research into the treatments for them., Competing Interests: DisclosureA conference abstract for a poster presentation of the review findings was published in July 2023: Talwar, S., Osorio, C., Appleton, R., & Billings, J.

Emerging evidence suggests that social identities are an important determinant of adaptation following traumatic life experiences. In this paper, we analyse accounts of people who experienced child sexual abuse. Using publicly available talk of people who waived their right to anonymity following successful conviction of perpetrators, we conducted a thematic analysis focusing on trauma-related changes in their social identities. Analysis of these accounts highlighted two themes. The first highlights the acquisition in these accounts of unwanted and damaging identity labels. The second presents child sexual abuse as a key destructive force in terms of important identity work during childhood. Discussion of this analysis centres on the pathological consequences of social identity change. Both the loss of valued identities and the acquisition of aberrant and isolating identities are experienced and constructed as devastating by those affected by child sexual abuse. This has important implications, not only for those impacted by child sexual abuse but for how abuse is discussed in society, and how it is approached by policy makers, educators and individuals working with survivors and their families., (© 2024 The Authors.

Purpose: Child maltreatment (CM) is associated with psychosis; however little is known about the frequency, type, and timing of abuse in the personality pathology domain of psychoticism (PSY) in the DSM-5. The purpose of this study was to analyze childhood trauma typology and frequency according to gender and to identify sensitive periods of susceptibility to CM in women with high PSY., Methods: The Maltreatment and Abuse Chronology Exposure (MACE) scale was used to evaluate the frequency, severity and timing of each type of maltreatment. The full sample consisted of 83 participants with different psychiatric diagnoses. Psychoticism was assessed with the DSM-5 Personality Inventory (PID-5). To identify the differences in CM exposure between the PSY+ (high psychoticism) and PSY- (low psychoticism) groups, the Mann-Whitney U test, the chi square test and random forest (RF) test were used., Results: Comparing PSY + and PSY-, revealed gender differences in the impact of abuse, with highly frequent and severe types of abuse, in women. In women, PSY + and PSY-, were differentiated especially in non-verbal emotional abuse, peer physical bullying and parental verbal abuse. Several periods with a major peak at age seven followed by peaks at age 17 and 12 years old were identified., Conclusion: Increased exposure to CM occurs in women with PSY+. A sensitivity to CM exposure during early childhood and late adolescence could be a risk factor for psychoticism in women., (© 2024.

Childhood maltreatment (CM) is associated with increased limbic activity, while social support is linked to decreased limbic activity towards negative stimuli. Our study aimed to explore the interaction of perceived social support with CM, and their combined impact on limbic activity in negative emotion processing. A total of 130 healthy individuals (HC) underwent a negative emotional face processing paradigm. They were divided into two groups based on the Childhood Trauma Questionnaire: n = 65 HC without CM matched with n = 65 HC with CM. In a region-of-interest approach of the bilateral amygdala-hippocampus-complex (AHC), regression analyses investigating the association of CM and perceived social support with limbic activity and a social support x CM ANCOVA were conducted. CM was associated with increased AHC activity, while perceived social support tended to be associated with decreased AHC activity during negative emotion processing. The ANCOVA showed a significant interaction in bilateral AHC activity (p FWE  ≤ 0.024) driven by a negative association between perceived social support and bilateral AHC activity in HC without CM. No significant association was observed in HC with CM. Exploratory analyses using continuous CM scores support this finding. Our results suggest that CM moderates the link between perceived social support and limbic activity, with a protective effect of perceived social support only in HC without CM. The lack of this effect in HC with CM suggests that CM may alter the buffering effect of perceived social support on limbic functioning, highlighting the potential need for preventive interventions targeting social perception of HC with CM., (© 2024.

Introduction: Childhood maltreatment, particularly emotional abuse (EA), has been identified as a significant risk factor for the development of eating disorders (EDs). This study investigated the association between EA and ED symptoms while considering multiple potential mediators., Methods: Participants included 151 individuals with Anorexia Nervosa (AN), 115 with Bulimia Nervosa (BN), and 108 healthy controls. The Childhood trauma questionnaire, the Toronto Alexithymia scale, the Behavioral inhibition System, and the Eating Disorder Inventory 2 scale were completed before treatment. A mediator path model was conducted in each group: EA was set as independent variable, eating symptoms as dependent variables and ineffectiveness, sensitivity to punishment, alexithymia, and impulsivity as mediators., Results: In individuals with AN, impulsivity emerged as a significant mediator between EA and desire for thinness and bulimic behaviors. Conversely, in individuals with BN, sensitivity to punishment was found to mediate the association between EA and dissatisfaction with one's body. Ineffectiveness and difficulty identifying emotions were identified as transdiagnostic mediators in both clinical groups. No mediation effect was found in healthy individuals., Discussion: The simultaneous assessment of multiple mediators in a unique model outlines the complex interplay between childhood EA and ED psychopathology. Improving ineffectiveness, emotion identification, sensitivity to punishment and impulsivity and exploring their relations with early emotional abuse may represent treatment targets in individuals with EDs and childhood trauma., Competing Interests: Declaration of competing interest The authors have no relevant financial or non-financial interests to disclose., (Copyright © 2024 The Authors.

The objective of this scoping review was to describe and synthesize the measures, methods, and key findings of published quantitative research examining the influence of child maltreatment (i.e., abuse and/or neglect) and adult trauma exposure on mental health symptoms among women Veterans. A systematic search from database inception to June 2023 generated 18,861 unique articles retrieved and independently screened for eligibility. A total of 21 articles met pre-established inclusion criteria: (a) quantitative data and results within a sample or subsample of U.S. women veterans, (b) published in a peer-reviewed journal, and (c) examining variables of interest simultaneously (i.e., child maltreatment, adult trauma exposure, mental health symptom) in quantitative analyses. Reviewed literature showed a lack of uniformity in measurement and methodologies to evaluate women veterans' lifetime trauma exposure in relation to mental health. Studies most frequently used self-report survey data to evaluate exposure to child maltreatment and/or adult trauma with convenience samples of women veterans (52.4%, n  = 11) and examined depressive and/or posttraumatic stress symptomatology. Findings demonstrate the need for additional research attending to the interplay between child maltreatment and adult trauma exposures in relation to women veterans' mental health using comprehensive assessment, longitudinal methods, and understudied as well as more representative samples., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: The views expressed in this article are those of the authors and do not necessarily reflect the position or policy of the Department of Veterans Affairs or the United States government.

WHAT IS KNOWN ON THE SUBJECT?: This paper acknowledges the profound and lasting impact of childhood abuse on substance use and homelessness. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: It underscores the inherent value and humanity of every individual, regardless of their struggles. That a comprehensive approach to mental health care, encompassing medication, therapy and a secure environment, is imperative. WHAT ARE THE IMPLICATIONS FOR MENTAL HEALTH NURSING?: Early intervention and recognising individuals who suffer in silence are paramount. Mental health nurses must have the courage to ask uncomfortable questions and truly hear the unspoken words. Mental health nurses should never underestimate the power of simply being present with someone during their darkest moments. This simple act can wield significant influence., (© 2024 The Authors.

Several researchers have found that men who have committed sexual aggression have inadequate coping strategies (e.g., paraphilic sexual fantasies, substance abuse). However, very few researchers have empirically examined the factors potentially associated with the development of these strategies. In 2011, Maniglio hypothesized that the inadequate coping strategies of men who have committed sexual aggression are the result of childhood victimization, mediated by internalized psychological problems. The present study therefore empirically tested this hypothesis in a Canadian sample of 205 men who had committed sexual aggression against women, of whom 37 committed sexual murder. Structural equation modeling (SEM) resulted in the identification of several direct and indirect trajectories leading from childhood victimization (psychological, physical, sexual) to the development of inadequate coping strategies (paraphilic sexual fantasies, alcohol and drug use) mediated by internalized psychological problems (e.g., anxiety, depression, social isolation). The theoretical and clinical implications of these developmental trajectories are discussed., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Childhood sexual abuse (CSA) continues to be a public health challenge. The prevalence of experiencing CSA is higher among men who have sex with men (MSM) than the general population. CSA has been linked to compulsive sexual behavior (CSB) among varying populations but has not been examined among MSM who were newly diagnosed with HIV. Therefore, the aims of this study were to assess the direct association between CSA and CSB among newly diagnosed MSM living with HIV, and to identify the potential mediating roles of depressive symptoms and emotion regulation in the association between CSA and CSB. The study was a secondary data analysis using data obtained from 2012 to 2017 from two community HIV clinics in New York City (n = 202). CSA was operationalized with questions asking about sexual abuse during childhood/adolescence. CSB was measured using the 13-item Compulsive Sexual Behavior Inventory (CSBI). Depressive symptoms were measured using the 20-item Centers for Epidemiologic Studies Depression (CES-D) scale and emotion regulation was measured using a 36-item Difficulties in Emotion Regulation Scale (DERS). Path analysis was conducted to determine the mediating role of depressive symptoms and emotion regulation in the association between CSA and CSB. There was a statistically significant association between CSA and CSB (β = 0.160; p = 0.019). There were statistically significant indirect associations between CSA, depressive symptoms, emotion regulation, and CSB (depressive symptoms β = 0.0.071; p = 0.010; DERS: β = 0.080; p = 0.006). Depressive symptoms were also correlated with emotion regulation (r = 0.596; p < 0.001). The relationship between CSA and CSB was significantly mediated by depressive symptoms and emotion regulation. Trauma-informed interventions addressing depressive symptoms and difficulties in emotion regulation may help to reduce CSB among MSM living with HIV., (© 2024. The Author(s).)

Existing research on the relationship between intimate partner violence (IPV) and cigarette smoking primarily involves low-risk, physical IVP-focused studies on community women. As a result, the risks associated with cigarette smoking in women victims of severe IPV have not been fully explored. This study examined the association between exposure to different forms of childhood maltreatment, exposure to physical, psychological, and sexual IPV, and current psychological distress symptoms with cigarette smoking in a high-risk sample of women victims of police-reported severe IPV. Participants included 162 women victims of police-reported severe IPV recruited in shelters for domestic violence and Child Protective Services in Portugal. Participants provided self-reports on childhood maltreatment physical, psychological, and sexual violence), physical, psychological, and sexual IPV, psychological distress symptoms (anxiety, depressive, somatic, and posttraumatic stress disorder symptoms), and daily cigarette consumption. Results revealed significant associations between daily cigarette consumption and exposure to IPV, physical abuse during childhood, psychological IPV, and anxiety symptoms in women experiencing police-reported severe IPV. Childhood maltreatment may increase vulnerability for emotion dysregulation, promoting addictive behaviors to regulate distress. Smoking can be an unhealthy regulating strategy to reduce the distress related to chronic exposure to psychological IPV. Future effective health promotion interventions in women facing severe forms of IPV may target emotional regulation and incorporate a trauma-focused approach.

Objective: Chronic childhood trauma is consistently linked to negative mental health outcomes in adulthood, but research exploring specific paths of risk remains limited. The aims of the current study were to examine trauma cognitions as intervening variables in the relation of chronic victimization with perceived burdensomeness and thwarted belongingness, variables implicated in transdiagnostic risk for psychopathology., Method: Semistructured interviews were used to identify university students reporting exposure to systematic physical and/or sexual violence prior to age 18 ( n = 101) versus those experiencing other Criterion-A events ( n = 254). Trauma cognitions (self, world, and self-blame) and thwarted interpersonal needs (burdensomeness and thwarted belongingness) were measured using scores from the posttrauma cognitions inventory (PTCI) and the Interpersonal Needs Questionnaire-10 (INQ-10). Path models in these cross-sectional data were evaluated to assess the indirect effects of chronic abuse on burdensomeness and thwarted belongingness through self, world, and blame cognitions., Results: An initial model indicated associations of chronic victimization on self ( p = .044) and world ( p = .005) scales of the PTCI and a unique effect of self-beliefs on INQ-10 burdensomeness ( p < .001). An indirect effect of abuse on burdensomeness through self-beliefs was supported ( p = .050). A second model identified direct effects of PTCI self ( p < .001) and world ( p < .001) scores on thwarted belongingness as well as an indirect effect of chronic abuse on belongingness through world beliefs (p = .026)., Conclusions: While typically assessed within the context of posttraumatic stress disorder, results suggest that shifts in fundamental beliefs about the self and the world may have more general impacts on perceptions of burdensomeness and belonging in survivors of early, systematic abuse.

Prolonged incest, where children are sexually abused by familial perpetrators into adulthood, has been documented in clinical and criminological scholarship, however it is often overlooked in research, policy and practice approaches to familial sexual abuse. This article draws on interviews with ten Australian therapists about their clinical work with clients subject to incestuous abuse continuing into adulthood. It outlines their descriptions of these cases, the nature of the reported abuse and factors that facilitated prolonged and ongoing incest, including at the time of therapy. The therapists and their clients were female. The clients were highly dissociative and experienced significant psychiatric and medical comorbidity, and extensive socio-economic disadvantage. Reported abuse was sadistic, ongoing, often involved multiple perpetrators, and sometimes had links to organized abuse. Therapists' conceptualizations of the factors related to the abuse included: enmeshed and disorganized attachment to the perpetrator; symptoms of severe dissociation; having absent, abusive or non-protective mothers; and social isolation which limited help-seeking. The study concludes that attachment, trauma and dissociation-informed therapy is essential, while further research is needed to further explore effective interventions and responses to this clinical cohort.

Emotional maltreatment (EM) is the most common retrospectively self-reported form of child abuse/neglect. One potential negative outcome for EM survivors is a lack of social connection (SC; i.e., feeling interpersonally distant from others, socially uncomfortable, etc.). Explanations of the link between EM and low SC, however, are insufficiently tested. Theory and empirical work point to shame as a ubiquitous consequence of EM that negatively affects self-concept and is also associated with low SC in adulthood., Objective: We test the hypothesis that experiences of EM lead to shame that impairs the development of social self-concept and, ultimately, one's sense of SC., Participants and Setting: We collected self-report data from 244 American college students., Method: Using structural equation modeling, we tested shame and social self-concept as sequential mediators of the path from EM to SC., Results: Shame and social self-concept mediated the relationship between EM and SC, bringing this direct path below significance. Social self-concept partially mediated shame and SC. Overall, our model accounted for 77% of the variability in SC., Conclusions: Children subjected to EM by caregivers are likely to experience themselves as deeply flawed (i.e., shame) and have difficulty developing a secure sense of themselves, especially as relational beings. Our results suggest that when shame interferes with the development of a positive social self-concept, survivors of EM are at-risk for low SC. Treatment implications include a focus on healing shame and building social self-concept. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Self-reported lost memory of child sexual abuse (CSA) can be mistaken for "repressed memory." Based on our longitudinal studies of memory and disclosure in child maltreatment victims who are now adults, we discuss findings relevant to "repressed memory cases." We examined relations between self-report of temporarily lost memory of CSA (subjective forgetting) and memory accuracy for maltreatment-related experiences (objective memory). Across two studies involving separate samples, we find evidence for memory suppression rather than repression: (1) Most adults who claimed temporary lost memory of CSA reported memory suppression and clarified that they could have remembered the event if asked; (2) subjective forgetting was positively associated with accurate objective memory for maltreatment-related experiences. Subjective forgetting was also related to increased adult trauma symptoms and related to childhood non-disclosure of CSA. Moreover, trauma-related psychopathology mediated the relation between non-disclosure and subjective forgetting. Implications for psychological theory and repressed memory cases are discussed., (© 2023 Cognitive Science Society LLC.)

Childhood maltreatment (CM) has been linked to social cognition deficits in major depressive disorder (MDD), but little is known about sex-specific effects. This study aimed to investigate the sex-specific associations of CM with social cognition in first-episode drug-naive patients with MDD. A total of 117 first-episode drug-naive patients with MDD and 134 healthy controls (HCs) were recruited and assessed for demographic and clinical characteristics. All participants completed the Childhood Trauma Questionnaire (CTQ), Toronto Alexithymia Scale (TAS-20), Interpersonal Reactivity Index-C (IRI), and Facial Emotion Recognition Test. Partial correlation analysis was used to explore the sex-specific association of CM with social cognition. Our findings revealed significant differences in the associations of CM with social cognition between males and females in MDD patients. In comparison to HCs, the associations of CM with social cognition displayed distinct and even contrasting sex-specific patterns in MDD patients. Specifically, male MDD patients exhibited unique imbalanced associations between emotional neglect and alexithymia, while both female and male MDD patients shared imbalanced associations of childhood abuse with empathy. These results emphasize the importance of considering the sex-specific associations of CM with social cognition in MDD and highlight the need for personalized interventions and treatments based on sex for MDD patients with a history of CM., (© 2023.

Background: Physical and sexual childhood abuse are associated with suicidal ideation and mental health disorders. However, less is known about non-physical types of maltreatment. This study examined associations between non-physical types of child maltreatment (e.g., emotional abuse, interpersonal aggression, exposure to physical intimate partner violence, emotional and physical neglect) and suicidal ideation, and mental health disorders., Data and Methods: Data from the 2018 Survey of Safety in Public and Private Spaces were used to estimate the proportion of individuals 15 years and older in Canada who experienced non-physical maltreatment during childhood. Multivariable regression analyses were used to examine associations between five types of non-physical child maltreatment and suicidal ideation, and mental health disorders., Results: Overall, interpersonal aggression was the most common (45.7%), followed by emotional abuse (40.4%) and emotional neglect (20.0%). Individuals who experienced any type of non-physical maltreatment in childhood had a higher probability of lifetime suicidal ideation than those who never experienced the maltreatment examined. Mood disorder diagnoses were more likely among those who experienced emotional abuse, interpersonal aggression, and emotional neglect than among those who never experienced these types of maltreatment. Compared with those who never experienced the maltreatment examined, individuals who experienced emotional abuse, interpersonal aggression, emotional neglect, or physical neglect were more likely to be diagnosed with an anxiety disorder. Diagnoses of post-traumatic stress disorder were more likely among those who experienced emotional and physical neglect than among those who never experienced these types of maltreatment., Interpretation: Non-physical child maltreatment is associated with suicidal ideation and mental health disorders. The findings highlight the importance of including non-physical types of child maltreatment on population-based surveys to differentiate associations with mental health outcomes to better align interventions and policies.

Background: Childhood maltreatment (CM) is prevalent among patients with mood disorders and considered an important risk factor for suicide in the general population. Despite mood disorders being implicated in up to 60 % of completed suicides, the predictive role of CM on suicide attempt (SA) among early mood disorder patients remains poorly understood., Methods: We enrolled 480 participants diagnosed with early-onset major depressive disorder (MDD), bipolar I disorder (BD I), and bipolar II disorder (BD II). Over an average of 60 weeks, participants underwent follow-up assessments at 12-week intervals. Using multivariate logistic regression, we examined the association between CM and SA history at baseline. Further, the Cox proportional hazard model assessed the predictive role of childhood maltreatment in SA during follow-up., Results: At baseline, 38 % of the total participants reported SA history, with a follow-up prevalence of 10 %. Childhood maltreatment was significantly associated with past SAs and was a robust predictor of future SA, adjusting for relevant clinical risk factors. Emotional abuse and sexual abuse related to SA history, and physical abuse increased future SA risk., Limitations: Potential biases in reporting SA and childhood maltreatment, along with unexplored factors such as additional environmental and familial risks, may affect the study's findings., Conclusions: Childhood maltreatment emerged as a robust predictor of SA among early-onset mood disorder patients. Systematic evaluation of CM early in the clinical process may be crucial for effective risk management. Additionally, our findings highlight the importance of implementing proactive interventions for CM to prevent the onset of adverse psychological trajectories., Competing Interests: Declaration of competing interest The authors declare that there is no conflict of interest., (Copyright © 2024 The Author(s).

Background: Mothers with a history of childhood maltreatment (CM) are particularly vulnerable to postpartum mental health changes. Variability in mental health trajectories is present over the first 18-months postpartum. Little is known about the potentially unique impacts of post-traumatic change or resilience on later postpartum mental health., Methods: Participants (N = 97) completed questionnaires over the first 18-months postpartum measuring demographic risk, mental health symptoms, traumatic experiences, and resilience. Mothers also completed an interview measure coded for post-traumatic changes at 6-months postpartum. Multinomial logistic regression models examined post-traumatic change and resilience factors as predictors of mothers' longitudinal latent mental health trajectory., Results: Three classes of latent postpartum mental health emerged: low-symptom, vulnerable, and chronic high-risk. Mothers reporting stronger positive post-traumatic changes were more likely to be in the low-symptom class than the chronic high-risk class (B = -1.082, p = .01). Mothers reporting stronger negative post-traumatic changes were more likely to be in the vulnerable class (B = 0.778, p = .006) or chronic high-risk class (B = 0.906, p = .046) than the low-symptom class. Resilience was not predictive of mental health class., Limitations: Findings are correlational, and causal effects between post-traumatic growth and mental health symptoms cannot be assumed. Mothers who consented to the interview may not be fully representative of all women who have experienced CM, limiting generalizability of findings., Conclusions: Positive post-traumatic change is associated with reduced psychopathology. These findings may assist in identification of mothers at greater risk of adverse postpartum outcomes and futher inform interventions focused on enhancing positive changes in post-traumatic cognitions., Competing Interests: Declaration of competing interest The authors have no disclosures to make., (Copyright © 2024 Elsevier B.V.

Background: Stigma is a key barrier to disclosing traumatic experiences of violence in childhood with adverse consequences for help-seeking behaviour. Disclosing behavior differs by gender and the form of violence experienced. However, there is a lack of comprehensive studies that address societal perceptions of males and females with a history of sexual or physical violence in childhood. Therefore, our aim is to focus on the impact of gender on the perception of individuals who experienced sexual or physical violence in childhood., Methods: We conducted a study on a representative sample of the German general population in terms of age and gender. Participants were randomly assigned to brief case vignettes addressing sexual or physical violence in childhood. Analyses base on a sample of n = 659 individuals (50.1% female). Stigma was assessed through examining respondents' readiness to address specific traumas in conversation and respondents' attitudes toward the individuals in the vignettes. Mann-Whitney U tests were applied to check for differences between female and male victims and survivors as well as female and male respondents., Results: Our results reveal that male victims and survivors face higher negative stereotypes (harm, unpredictability) and evoke communication barriers more often when compared to female victims and survivors, especially in male respondents. Sexual violence is associated with more distinct gender differences than physical violence., Conclusions: Findings reflect greater stigma toward male victims and survivors of sexual violence than female ones. Men had a greater tendency to stigmatize - especially toward their same-gender peers. Socially ingrained gender roles may act as a basis for different communication cultures and the notion of victim-perpetrator constellations in which males are not envisaged as victims., (© 2024.

While prior research has studied associations between child abuse and nonsuicidal self-injury (NSSI), there is limited research assessing unwanted pursuit behavior (UPB) victimization and NSSI. In addition, few studies have assessed the self-reported functions of NSSI among survivors of violence. Among a sample of 18-25-year-old young adults ( N = 333), both UPB victimization and child abuse were significantly associated with NSSI frequency. In regression models, UPB victimization was associated with increased use of affect regulation, antidissociation/feeling-generation, self-punishment, and antisuicide functions, while child abuse was associated only with antidissociation/feeling-generation and self-punishment. Affect regulation mediated the association between UPB victimization and NSSI frequency, but not the association between child victimization and NSSI frequency. Implications for research and clinical practice will be discussed., (© 2024 Springer Publishing Company, LLC.)

Childhood maltreatment, alexithymia and impulsivity are related to bipolar disorder (BD), but the role of potential underlying mechanisms of this link, such as extreme sensory processing, in BD are unclear. This study compared sensory processing patterns between individuals with BD-I or BD-II and between those with and without alexithymia and childhood maltreatment. Additionally, the study aimed to examine the role of extreme sensory processing in the relationship between childhood trauma, alexithymia and impulsivity with both depression and mania in a sample of hospitalized individuals with BD (n = 300). Participants completed self-report and clinician-rated scales. Patients with BD-II exceeded those with BD-I in low registration, sensory sensitivity and sensation avoidance, whereas patients with BD-I exhibited a more heightened sensation-seeking pattern. Patients with BD who had alexithymia and a history of childhood maltreatment exhibited more heightened sensory processing patterns, apart from sensory seeking, compared to those without alexithymia and childhood maltreatment. Additionally, the same pattern was more pronounced in individuals with BD who had both alexithymia and childhood maltreatment compared to those with either condition or neither of these conditions. The pathways from childhood maltreatment and alexithymia to depressive symptoms were mediated by low registration and sensation avoidance. Sensory seeking indirectly affected the link between alexithymia and manic symptoms. Childhood maltreatment and challenges in effectively processing emotional information, along with their related hypo- and hypersensitivity, may characterize BD individuals and its manifestation of depressive and manic symptoms., (© 2024 John Wiley & Sons Ltd.)

Background: Although maternal childhood maltreatment has been associated with offspring externalizing symptoms, little is known about the potential mechanisms that contribute to breaking the intergenerational effect of maternal childhood maltreatment., Objective: The current study aimed to (a) investigate the intergenerational effect between maternal childhood maltreatment and offspring externalizing symptoms in the Chinese family; (b) examine maternal supportive and harsh parenting as potential mediators of this intergenerational effect; and (c) explore the moderating roles of paternal support parenting, as well as paternal harsh parenting, in this mediation process of maternal supportive and harsh parenting., Participants and Setting: The sample consisted of 1111 mother-father-child triads from Beijing, recruited when the children were one and three years old., Methods: Mothers completed the Childhood Trauma Questionnaire, and both parents completed the Infant-Toddler Social and Emotional Assessment and Comprehensive Early Childhood Parenting Scale., Results: Our results showed that maternal childhood maltreatment was a risk factor for offspring externalizing symptoms at T2 (β = 0.24, t = 6.51, p < .001), and this effect was mediated by maternal supportive (indirect effect = 0.03, 95%CI = [0.02, 0.05]) and harsh parenting (indirect effect = 0.03, 95%CI = [0.02, 0.07]) at T1. Furthermore, paternal harsh parenting moderated the indirect effect of maternal childhood maltreatment on child externalizing symptoms through maternal supportive parenting., Conclusions: These findings contribute to our understanding and provide valuable information for disrupting the intergenerational effect of maternal childhood maltreatment., Competing Interests: Declaration of competing interest On behalf of all authors, the corresponding author states that there is no conflict of interest., (Copyright © 2024.

Men who have sex with men (MSM) with history of childhood sexual abuse (CSA) are at high risk for HIV acquisition. One reason is posttraumatic responses compromise ability to accurately appraise risk for danger/vulnerability. Health behavior change models and related interventions assume risk perception can be changed in an enduring manner. Given paucity of studies examining how risk perception changes or sustains over time post-intervention, this underlying assumption is not confirmed. Among this particularly high-risk group who struggle with perceiving risk due to trauma-related cognitions, it may be accuracy of risk perception is fluid. The study primarily aimed to examine accuracy of HIV risk perception over time post-HIV prevention behavioral intervention. Leveraging data from a larger RCT, N = 190 MSM in Boston, MA and Miami, FL USA completed a psychosocial baseline assessment, an intervention aimed to increase awareness of personal HIV risk level, then four follow-up assessments three months apart for a year. Linear mixed effect models were used to examine the degree to which accuracy of HIV risk perception (vs. traditional construct of risk perception with no information about accuracy) predicts sex risk behavior over time delineated by between-person (trait level) and within-person (state level) effects. Majority (92%) of participants fluctuated in HIV risk accuracy over time post-intervention. Within-person risk accuracy (one's accuracy at any given timepoint) predicted sex risk behavior (condomless sex not protected by adherent PrEP) over time, but not between-person (one's average of accuracy). Findings have implications for intervention and counseling related to specific HIV prevention strategies., (© 2024.

Background and Objectives: Individuals with comorbid substance use and mental health disorders (concurrent disorders; CD) report poor treatment outcomes, high prevalence of childhood maltreatment, and mostly negative experiences with treatment. No studies to date have examined childhood maltreatment and treatment outcomes in CD. This study investigated self-reported childhood maltreatment as it relates to treatment satisfaction and substance use relapse among CD patients., Methods: The 258 CD inpatients completed a self-report questionnaire package, comprising the Childhood Trauma Questionnaire and the Inpatient Consumer Survey (ICS). Childhood maltreatment was assessed according to five subtypes and self-perceived treatment satisfaction was rated across six ICS domains. Psychiatric diagnoses, substance use status and relapse data were retrieved via patient medical charts., Results: Emotional neglect was associated with lower ratings across all ICS domains and physical neglect was associated with a lower rating for 'outcome of care'. Childhood sexual abuse was associated with a greater likelihood of alcohol relapse. No other relationships were statistically significant., Discussion and Conclusions: The presence of childhood neglect (but not abuse) was more associated with overall treatment dissatisfaction, and sexual abuse alone increased the likelihood of alcohol relapse. These findings suggest some early adverse experiences in CD patients may increase negative experiences in treatment while others contribute to the risk of substance use. Broader longitudinal research is needed to examine the trajectory leading to negative outcomes., Scientific Significance: This is the first study to report differential patterns of association by type of childhood maltreatment on negative outcomes in treatment among CD patients., (© 2024 The American Academy of Addiction Psychiatry (AAAP).)

Background: Childhood abuse is associated with an increased risk of migraines. However, the literature on this association is limited., Objective: To determine the pooled effect size of the association between childhood abuse and migraines., Participants and Setting: System review and meta-analysis., Methods: A systematic literature search for studies published until September 20, 2023, was performed using the Embase, PubMed, and Web of Science databases. Specifically, original articles reporting the statistical effect size (odds ratio) of the association between childhood abuse and migraines were selected. Pooled odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated using random- or fixed-effects models. Publication bias was examined using funnel plots, and sensitivity analysis was used to explore the stability of the pooled results., Results: Twelve studies involving 110,776 participants were included. Individuals with childhood abuse (OR = 1.60, 95 % CI: 1.49, 1.71) were at increased risk of migraine when compared with individuals with no childhood abuse. Of the different types of childhood abuse examined, sexual abuse (OR = 1.71, 95 % CI: 1.43, 2.04), physical abuse (OR = 1.47, 95 % CI: 1.38, 1.56), and emotional abuse (OR = 1.71, 95 % CI: 1.52, 1.93) were associated with an increased risk of migraine., Conclusions: Childhood abuse increases migraine risk. Multifaceted interventions to curb abuse and related behaviors can effectively reduce migraine risk. However, considering that multiple factors, such as obesity and anxiety, are causatively associated with both childhood abuse and migraines, our findings should be interpreted with caution., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

Abstract: Schizophrenia is a debilitating mental health disorder that imposes profound economic, societal, and personal burdens. The negative symptoms of schizophrenia ( i.e. , blunted affect, alogia, anhedonia, asociality, and avolition) are highly prevalent and pervasive in the psychotic disorder and pose significant resistance to available treatment options. Traumatic childhood experiences are strongly linked with the risk of developing schizophrenia. Most prior studies have primarily focused on positive symptoms of schizophrenia ( e.g. , hallucinations and delusions), whereas less attention has been given to negative symptoms. The current study investigated the relationship between childhood trauma ( i.e. , physical abuse, sexual abuse, and emotional abuse and neglect) and negative symptoms in a sample of schizophrenia outpatients and healthy controls ( n = 159 participants, including 99 patients with schizophrenia). The observations from the current study revealed that schizophrenia patients experienced a significantly greater degree of childhood trauma and negative symptoms than the control individuals. The results of the current study also indicated that more severe experiences of total childhood trauma ( i.e. , summation of all trauma types), physical abuse, and emotional neglect may increase the risk of schizophrenia patients reporting negative symptoms. However, childhood sexual and emotional abuse was found to have no impact on the degree of negative symptoms experienced by schizophrenia patients. Implications and limitations of the current study are discussed. In conclusion, we found that the severity of overall childhood trauma, physical abuse, and emotional neglect may play an important role in increasing the likelihood of schizophrenia patients reporting negative symptoms., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Cognitive deficits might contribute to the elevated risk of life-course psychopathology observed in maltreated children. Leading theories about the links between childhood maltreatment and cognitive deficits focus on documented exposures (objective experience), but empirical research has largely relied on retrospective self-reports of these experiences (subjective experience), and the two measures identify largely non-overlapping groups. We aimed to test the associations of objective and subjective measures of maltreatment with cognitive abilities within the same individuals., Methods: We studied a cohort of individuals from the US Midwest with both objective, court-documented evidence of childhood maltreatment and subjective self-reports of individuals' histories at age 29 years. Between the ages of 29 years and 41 years, participants were assessed with a comprehensive set of cognitive tests, including tests of general verbal intelligence (Quick Test and Wide Range Achievement Test-Revised [WRAT]), non-verbal intelligence (Matrix Reasoning Test [MRT]), executive function (Stroop Test and Trail Making Test Part B [TMT-B]), and processing speed (Trail Making Test Part A [TMT-A]). Participants were also assessed for psychopathology (Center for Epidemiologic Studies Depression Scale and Beck Anxiety Inventory). We tested the associations between objective or subjective measures of childhood maltreatment with cognitive functions using ordinary least squares regression. To test whether cognitive deficits could explain previously described associations between different measures of maltreatment and subsequent psychopathology, we re-ran the analyses accounting for group differences in the Quick Test. People with lived experience were not involved in the research or writing process., Findings: The cohort included 1196 individuals (582 [48·7%] female, 614 [51·3%] male; 752 [62·9%] White, 417 [34·9%] Black, 36 [3·8%] Hispanic) who were assessed between 1989 and 2005. Of the 1179 participants with available data, 173 had objective-only measures of childhood maltreatment, 492 had objective and subjective measures, 252 had subjective-only measures, and 262 had no measures of childhood maltreatment. Participants with objective measures of childhood maltreatment showed pervasive cognitive deficits compared with those without objective measures (Quick Test: β=-7·97 [95% CI -9·63 to -6·30]; WRAT: β=-7·41 [-9·09 to -5·74]; MRT: β=-3·86 [-5·86 to -1·87]; Stroop Test: β=-1·69 [-3·57 to 0·20]; TMT-B: β=3·66 [1·67 to 5·66]; TMT-A: β=2·92 [0·86 to 4·98]). The associations with cognitive deficits were specific to objective measures of neglect. In contrast, participants with subjective measures of childhood maltreatment did not differ from those without subjective measures (Quick Test: β=1·73 [95% CI -0·05 to 3·50]; WRAT: β=1·62 [-0·17 to 3·40]; MRT: β=0·19 [-1·87 to 2·24]; Stroop Test: β=-1·41 [-3·35 to 0·52]; TMT-B: β=-0·57 [-2·69 to 1·55]; TMT-A: β=-0·36 [-2·38 to 1·67]). Furthermore, cognitive deficits did not explain associations between different measures of maltreatment and subsequent psychopathology., Interpretation: Previous studies based on retrospective reports of childhood maltreatment have probably grossly underestimated the extent of cognitive deficits in individuals with documented experiences of childhood maltreatment, particularly neglect. Psychopathology associated with maltreatment is unlikely to emerge because of cognitive deficits, but might instead be driven by individual appraisals, autobiographical memories, and associated schemas., Funding: National Institute of Justice, National Institute of Mental Health, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institute on Aging, Doris Duke Charitable Foundation, and National Institute for Health and Care Research., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 The Author(s).

Background: The study aimed to investigate the potential link between a history of childhood sexual abuse (CSA) and the experience of technology-facilitated sexual violence on dating apps (TFSV), considering distinct motivations for app usage among CSA survivors., Objective: To explore the association between CSA and TFSV on dating apps, while also examining the potential moderating role of motivations for app usage and differences based on sexual orientation., Participants and Setting: The study utilized an online survey among 534 dating app users in Israel., Methods: Participants completed an online survey assessing history of CSA, experiences of TFSV on dating apps, and motivations for app usage., Results: The study found that individuals with a history of CSA experienced more TFSV on dating apps. Survivors of CSA showed lower motivation for love and higher motivation for self-worth validation, ease of communication, and thrill of excitement. Differences between heterosexual and LGBTQ+ participants were observed, with LGBTQ+ individuals reporting higher levels of CSA prevalence and TFSV on dating apps. Motivations for app usage and sexual orientation were found to moderate the association between CSA history and TFSV on dating apps. Among LGBTQ+ participants, those who experienced CSA had a higher likelihood of encountering TFSV on dating apps, regardless of their motivations. Heterosexual individuals with a history of CSA were more prone to TFSV on dating apps if they had a strong motivation for love., Conclusions: This study shed light on unique vulnerabilities among individuals with a history of CSA, including increased susceptibility to TFSV on dating apps., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2024 Elsevier Ltd.

Background: In the 1990s, the concepts of hikikomori and modern-type depression (MTD) emerged in Japan. Hikikomori is a condition of social avoidance or isolation, characterized by staying at home and being physically isolated for at least six months. MTD is characterized by depressive symptoms-mainly in stressful work or school situations during adolescence and early adulthood-which tend to rapidly reduce or disappear after leaving the stressful situation. We hypothesized that childhood maltreatment can form MTD traits that lead to hikikomori., Methods: As a first step, we conducted a multigroup path analysis between childhood maltreatment, MTD traits, and physical isolation in the hikikomori group. This study utilized the nine-item Patient Health Questionnaire (PHQ-9), Home Environment Questionnaire (HEQ), 22-item Tarumi Modern-Type Depressive Trait Scale (TACS-22), 25-item Hikikomori Questionnaire (HQ-25), and Hamilton Depression Rating Scale (HDRS). The HQ-25 contains three factors: physical isolation, lack of socialization, and lack of emotional support., Results: The hikikomori group included 92 patients and the control group comprised 137 healthy individuals. All total and subscale scores of PHQ-9, HEQ, TACS-22, HQ-25, and HDRS were significantly higher in the hikikomori group than in the control group. The risk model of childhood maltreatment for physical isolation via MTD traits obtained good fit with a goodness-of-fit index of.982., Limitations: The study's limitations were its sample selection bias, cross-sectional design, and use of self-report scales., Conclusions: Our findings support the hypothesis that childhood maltreatment is an important risk factor for hikikomori via MTD traits., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Maternal childhood maltreatment (CM) has been repeatedly associated with negative offspring's emotional outcomes. The dysregulation of the Hypothalamic-Pituitary-Adrenal (HPA) axis has emerged as the main underlying physiological mechanism., Objective: To explore the association between maternal CM and newborns' physiological and neurobehavioral stress responses, considering the role of perinatal maternal depression and bonding., Participants and Setting: 150 healthy women were followed throughout pregnancy. 79 mother-infant dyads were included in the final analyses. Maternal CM was evaluated using the Childhood Trauma Questionnaire and depressive symptoms by the Edinburgh Postnatal Depression Scale (EPDS) at each trimester. At 7 weeks postpartum, the EPDS and the Postpartum Bonding Questionnaire were administered. Newborns' behavioral responses were assessed using "States Organization" (SO) and "States Regulation" (SR) subdomains of the Neonatal Behavioral Assessment Scale (NBAS). Newborns' salivary samples were collected before and after the NBAS to study cortisol reactivity., Methods: A cross-lagged panel model was employed., Results: Infants born to mothers with higher CM presented more optimal scores on SO (β (0.635) = 0.216, p 〈001) and SR (ß (0.273) = 0.195, p = .006), and a higher cortisol reactivity after NBAS handling (β(0.019) = 0.217, p = .009). Moreover, newborns of mothers with higher CM and postpartum depressive symptoms exhibited a poorer performance on SR (ß (0.156 = -0.288,p = .002). Analyses revealed non-significant relationships between mother-infant bonding, newborns' cortisol reactivity and SO., Conclusions: Newborns from mothers with greater CM present higher cortisol reactivity and more optimal behavioral responses, which may reflect a prenatal HPA axis sensitization. However, those exposed to maternal postnatal depressive symptoms present poorer stress recovery., Competing Interests: Declaration of competing interest Authors declare no conflict of interest., (Copyright © 2024 The Authors.

There are individual effects of alexithymia, childhood maltreatment, impulsivity, and some biological markers on aggression and psychological distress in schizophrenia. However, the combined effects of these psychological and biological markers have not yet been fully studied. This study therefore aimed to investigate the influence of these psychological and biological markers on aggression and psychological distress (e.g., depression and anxiety) in inpatients with schizophrenia (n = 355). Participants completed self-report and clinician-rated scales, and blood samples were collected. There were no significant differences between patients with and without alexithymia regarding biological markers. Patients with childhood maltreatment exhibited higher levels of free triiodothyronine (FT3) and C-reactive protein (CRP), as well as lower total cholesterol (TC) levels, compared to non-traumatized individuals. Aggression was positively predicted by psychological distress, alexithymia, childhood maltreatment, impulsivity, CRP, and FT3, and negatively by TC and low-density lipoprotein cholesterol. Negative symptoms, childhood maltreatment, alexithymia, aggression, and CRP positively, and high-density lipoprotein cholesterol negatively emerged as predictors of psychological distress. The study highlights the connections between childhood maltreatment, alexithymia, impulsivity, and potentially related biological dysregulation in explaining aggression and negative mood states as a bio-psychological model of aggression and mood in schizophrenia., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objective: Patients who have experienced child abuse often have complex clinical presentations; whether a history of child abuse (HCA) affects psychotherapy outcomes is unclear. The authors examined relationships between HCA, clinical baseline variables, and change in these variables after three different psychotherapies for panic disorder (PD)., Methods: Two hundred adults with PD (with or without agoraphobia) were randomly assigned to one of three treatments across two sites: panic-focused psychodynamic psychotherapy (PFPP), cognitive-behavioral therapy (CBT), or applied relaxation training (ART). Differences in demographic and clinical variables between those with and without HCA were compared. The primary analysis addressed odds of meeting clinical response criteria on the Panic Disorder Severity Scale (PDSS) between treatments, as moderated by HCA. This effect was examined via continuous outcomes on the PDSS and psychosocial functioning (Sheehan Disability Scale)., Results: Compared with patients without HCA (N=154), patients with HCA (N=46) experienced significantly more severe symptoms of PD (d=0.60), agoraphobia (d=0.47), and comorbid depression (d=0.46); significantly worse psychosocial impairment (d=0.63) and anxiety sensitivity (d=0.75); greater personality disorder burden (d=0.45)-particularly with cluster C disorders (d=0.47)-and more severe interpersonal problems (d=0.54). HCA significantly moderated the likelihood of clinical response, predicting nonresponse to ART (B=-2.05, 95% CI=-4.17 to -0.30, OR=0.13, z=-2.14, p=0.032) but not CBT or PFPP. HCA did not interact with treatment condition to predict slopes of PDSS change., Conclusions: The results of this study highlight the importance of HCA in formulating treatment recommendations. Increased awareness of HCA's effects on severity of PD and treatment responsiveness among patients with PD may improve outcomes., Competing Interests: Dr. Milrod reports receiving book royalties from the Taylor & Francis Group.

Background: Child maltreatment is a broadly confirmed risk factor for mental and physical illness. Some psychological treatments specifically target mental health conditions associated with child maltreatment. For example, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) focuses on maladaptive interpersonal behaviours in chronic depression. However, how the assessment of child maltreatment could inform personalised treatment is unclear. We used data from a previously published clinical trial to investigate whether a pre-established child maltreatment clustering approach predicts differential outcomes after CBASP versus non-specific supportive psychotherapy in patients with early-onset chronic depression., Methods: We did a cluster analysis of data from a previous randomised controlled trial of unmedicated adult outpatients with early-onset chronic depression who were treated at eight university clinics and psychological institutes in Germany with 32 sessions of CBASP or non-specific supportive psychotherapy. Participants were eligible for the original trial if they were aged 18-65 years; had major depressive disorder (MDD) with an early onset and duration of at least 2 years, current MDD superimposed on a pre-existing dysthymic disorder, or recurrent MDD with incomplete remission between episodes as defined by DSM-IV; and had a score of at least 20 points on the 24-item Hamilton Rating Scale for Depression (HRSD-24). Participants were included in the current study if they had completed the short form of the Childhood Trauma Questionnaire (CTQ) at trial baseline. We used an agglomerative hierarchical clustering approach to derive child maltreatment clusters from individual patterns across the five domains of the CTQ. We used linear mixed models to investigate whether clustering could predict differential clinical outcomes (change in symptom severity on the HRSD-24) up to 2 years after treatment onset. People with lived experience were involved in the current study., Findings: 253 patients (129 [51%] treated with CBASP and 124 [49%] with supportive psychotherapy) had complete CTQ records and were included in the analysis. 169 (67%) participants were women, 84 (33%) were men, and the mean age was 45·9 years (SD 11·7). We identified seven child maltreatment clusters and found significant differences in treatment effects of CBASP and supportive psychotherapy between the clusters (F (6,948·76) =2·47; p=0·023); differences were maintained over the 2-year follow-up. CBASP was superior in distinct clusters of co-occurring child maltreatment: predominant emotional neglect (change in β -6·02 [95% CI -11·9 to -0·13]; Cohen's d=-0·98 [95% CI -1·94 to -0·02]; p=0·045), predominant emotional neglect and abuse (-6·39 [-10·22 to -2·56]; -1·04 [-1·67 to -0·42]; p=0·0011), and emotional neglect and emotional and physical abuse (-9·41 [-15·91 to -2·91]; -1·54 [-2·6 to -0·47]; p=0·0046)., Interpretation: CTQ-based cluster analysis can facilitate identification of patients with early-onset chronic depression who would specifically benefit from CBASP. Child maltreatment clusters could be implemented in clinical assessments and serve to develop and personalise trauma-informed care in mental health., Funding: The German Research Foundation and the German Federal Ministry of Education and Research., Competing Interests: Declaration of interests SG has received book royalties from Elsevier.

Objectives: Childhood maltreatment has long-lasting effects on mental health. Existing evidence suggests that trajectories of depressive symptoms vary among individuals; however, little is known about how childhood maltreatment shapes these trajectory patterns. Therefore, this study investigated the impacts of childhood maltreatment on eight-year depressive trajectories among Chinese older adults., Method: Five waves of longitudinal data from the China Health and Retirement Longitudinal Study were utilized. Growth Mixture Modelling was performed to identify distinct trajectories of depressive symptoms, and multinomial logistic regression was conducted to explore the associations between these trajectories and childhood maltreatment., Results: Four trajectories of depressive symptoms were identified: the 'no symptoms' class (61.83%), the 'increasing symptoms' class (14.49%), the 'decreasing symptoms' class (16.44%), and the 'chronic symptoms' class (7.24%). Older adults who experienced childhood physical abuse were more likely to be in the 'chronic symptoms' class than in the 'no symptoms' class, whereas emotional neglect did not show a significant association with three problematic trajectories., Conclusion: This study provides empirical evidence that childhood physical abuse increases the likelihood of developing chronic depressive symptoms in later life. To mitigate this risk, it is crucial to institute comprehensive treatment plans that incorporate trauma-informed care principles, employ evidence-based therapies specifically designed to address the long-term effects of abuse, and prioritize regular screening and assessment of mental health among older adults.

Background: Postpartum psychosis (PP) is a psychological emergency requiring rapid intervention, hospitalization and psychiatric management. However, PP has been neglected in the postpartum literature. Understanding the detrimental consequences of childhood trauma across mother's life span is crucial to prevent this serious condition. The study's objectives were to demonstrate the relationship between childhood trauma and postpartum psychotic experiences (PPEs) and to look over the mediating role of postnatal depression (PD) and anxiety (PA) in this relationship., Methods: This cross-sectional study, which enrolled 438 postpartum females 4-6 weeks after delivery (mean age: 31.23 ± 5.24 years), was carried out from September 2022 to June 2023. The Arabic validated versions of the Postpartum Psychotic Experiences Scale, the Edinburgh Postnatal Depression Scale, the Perinatal Anxiety Screening Scale, and the Child Abuse Self Report Scale were used., Results: Both PD and PA partially mediated the correlation between psychological abuse and PPEs, and fully mediated the association between neglect and PPEs. Higher psychological abuse and neglect were significantly associated with higher PD (Beta = 1.11) and PA (Beta = 3.94), higher PD (Beta = 0.84) and PA (Beta = 0.26) were significantly associated with higher PPEs in both models, whereas greater child psychological abuse (Beta = 1.37) (but not neglect) was directly and strongly correlated with higher PPEs in all models., Conclusion: The significant mediating effect of PA and PD on the association between childhood adversities and PPEs among postpartum females may offer additional therapeutic avenues to help attenuate various postpartum mental health issues and their potential serious risks on both mother and child., (© 2024.

Background: Child sexual abuse is a universal social challenge and the victims of childhood sexual abuse suffer a range of short and long term psychological, social, behavioral and physical problems that vary in different cultures. The study was carried out to explore the perceived impacts of childhood sexual abuse in Pakistan, because no such study was conducted in Pakistan earlier., Methods: Interpretative phenomenological analysis was used to analyze the data. A snowball sampling technique was used to approach the sample of current study. The sample of the study comprised ten female survivors of childhood sexual abuse of age ranged between 18 and 22 years (M age = 20.10 years) with the education ranging from matric to BSc. Out of these participants, four were married and six were unmarried and belonged to different cities of Punjab, Pakistan. Data were collected via a semi-structured interview schedule and all interviews were verbatim transcribed., Results: A rigorous iterative process of data analysis resulted in three super-ordinate themes and ten sub-ordinate themes: Experiencing Abuse (emotional trauma, and physical distress), Psycho-social Distress (low self-esteem, negative self-concept, psychological pain, social suffering, and retaliation vs. forgiveness), and Sexual Difficulties (passive role, emotionally aloof, aversion from hetero-sexuality and avoidance)., Conclusion: It was concluded that childhood sexual abuse is an intense experience that has short- and long-term negative impacts on the lives of female survivors and engulfs their lives as a whole. The study has implications for psychiatrists, psychologists, family counselors, social scientists, educationists, and parents., (© 2024. The Author(s).)

Childhood maltreatment (CM) is thought to be associated with altered responses to social stimuli and interpersonal signals. However, limited evidence exists that CM is linked to larger comfortable interpersonal distance (CID) - the physical distance humans prefer towards others during social interactions. However, no previous study has investigated this association in a comprehensive sample, yielding sufficient statistical power. Moreover, preliminary findings are limited to the European region. Finally, it is unclear how CM affects CID towards different interaction partners, and whether CID is linked to social functioning and attachment. To address these outstanding issues, adults (N = 2986) from diverse cultures and socio-economic strata completed a reaction time task measuring CID towards an approaching stranger and friend. Higher CM was linked to a larger CID towards both friends and strangers. Moreover, insecure attachment and less social support were associated with larger CID. These findings demonstrate for the first time that CM affects CID across countries and cultures, highlighting the robustness of this association., (© 2024. The Author(s).)

Childhood trauma is widely recognized as a potential risk factor for psychiatric illness in adulthood, yet the precise mechanisms underlying this relationship remain incompletely understood. One proposed mechanism involves the impact of childhood trauma on personality development, particularly in relation to neuroticism, which may subsequently heighten susceptibility to psychiatric disorders. In this study, we aimed to investigate this hypothesis through an online survey involving 1116 participants (232 male, 21 %). Participants completed the Childhood Trauma Questionnaire (CTQ), assessing emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect, along with the Trait Self-Description Inventory (TSDI) for personality assessment and the PHQ-9 and GAD-7 clinical questionnaires for depression and anxiety symptoms evaluation, respectively. Our analyses revealed significant positive correlations between all facets of childhood trauma and neuroticism (all p < .01). Linear regression analysis demonstrated that emotional abuse significantly contributed to neuroticism (β = 0.267, p < .05), openness (β = 0.142, p < .05), and agreeableness (β = 0.089, p < .05), while sexual abuse was associated with agreeableness (β = 0.137, p < .01) Emotional neglect was negatively correlated with conscientiousness (β = -0.090, p < .01), extroversion (β = -0.109, p < .01) and agreeableness (β = -0.154, p < .01). Furthermore, linear regression analysis revealed that emotional abuse was positively and significantly correlated with PHQ-9 and GAD-7 scores (r = 0.330, p < .01 and r = 0.327, p < .01, respectively). Mediation analysis supported a significant mediating role of neuroticism in the association between childhood emotional abuse and both depression (PHQ-9) (z = 8.681, p < .01) and anxiety (GAD-7) (z = 9.206, p < .01). Notably, the correlation between childhood emotional abuse and psychiatric symptoms was attenuated but not eliminated after controlling for neuroticism, suggesting partial mediation. While our cross-sectional design precludes causal inference, our findings support the notion that childhood emotional abuse may contribute to increased neuroticism, thereby elevating vulnerability to affective disorders in adulthood. These results underscore the importance of considering personality factors in understanding the long-term consequences of childhood trauma on mental health outcomes., Competing Interests: Declaration of competing interest This study was funded by The Centre for Affective Disorders, Institute of Psychiatry, Psychology & Neuroscience (IoPPN), and King's College London.

Background: Individuals with a history of Adverse Childhood Experiences (ACEs) are at risk of subsequent cannabis use. However, at present no existing systematic review explores ACEs as they relate to cannabis use., Objective: The aim of this systematic review paper is to examine how adverse childhood experiences (ACEs) impact rates, patterns, and the nature of cannabis use in adulthood., Methods: Guided by the PRISMA statement, this systematic review focuses on longitudinal studies that report cannabis use in adulthood. Databases searched include PubMed and Embase., Results: Ultimately, 28 manuscripts were selected for inclusion, ranging in scope from smaller community-focused studies to nationally representative longitudinal surveys; 22 of 28 studies occurred in the United States, with sample size ranging from 303 to 15,960 participants. Instruments used to assess ACEs and cannabis use varied considerably across studies, leading to loss of consistency. Nevertheless, presence of ACEs-childhood sexual abuse in particular-was consistently associated with cannabis use later in life. Frequency and severity of ACEs was found to exert an additive cumulative effect on severity of cannabis use., Conclusions: This systematic review lays the foundation of the current state of the science regarding ACEs and cannabis use, which can provide further insight into a better understanding of this relationship and provide potential intervention opportunities., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest related to this manuscript., (Copyright © 2024 Elsevier Ltd.

Background: Child maltreatment (CM) includes neglect, and several types of abuse, including physical, emotional, and sexual. CM has been associated with a wide range of mental illnesses. Literature examining these illnesses in mid-life is scarce, and the impact of these illnesses on mental health service use is currently unknown., Objective: To examine associations between self-reported CM and subsequent hospital admissions for mental illnesses, and/or community mental health service contacts., Setting: Birth cohort study data linked to administrative health data, including hospital admissions and community mental health service contacts, up to the age of 40., Methods: Associations between hospital admissions for mental health and community mental health contacts and CM subtypes (neglect, physical abuse, emotional abuse and sexual abuse) were examined using multivariate logistic regression., Results: Adjusted analyses showed that all subtypes of CM were significantly (p < 0.05) associated with admissions to hospital for any type of mental illness (aOR range 1.87-3.61), non-psychotic mental disorders (aOR range 1.98-3.61), alcohol and/or substance use (aOR range 2.83-5.43), and community mental health service contacts (aOR range 2.44-3.13). Hospital admissions for psychotic mental disorders were significantly associated with physical abuse, emotional abuse, and sexual abuse (aOR range 2.14-3.93)., Conclusions: The results of this study confirm the current knowledge around CM and subsequent mental health illnesses up to the age of 40, and extend this knowledge to hospital and mental health service use., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Importance: The proportion of mental disorders and burden causally attributable to childhood maltreatment is unknown., Objective: To determine the contribution of child maltreatment to mental health conditions in Australia, accounting for genetic and environmental confounding., Design, Setting, and Participants: This meta-analysis involved an epidemiological assessment accounting for genetic and environmental confounding between maltreatment and mental health and 3 cross-sectional national surveys: the Australian Child Maltreatment Study (ACMS) 2023, National Study of Mental Health and Well-being 2020-2022, and Australian Burden of Disease Study 2023. Causal estimates were derived on the association between childhood maltreatment and mental health conditions from a meta-analysis of quasi-experimental studies. This was combined with the prevalence of maltreatment from the ACMS to calculate the population attributable fraction (PAF). The PAF was applied to the number and burden of mental health conditions in Australia, sourced from 2 population-based, nationally representative surveys of Australians aged 16 to 85 years, to generate the number and associated burden of mental disorders attributable to child maltreatment., Exposure: Physical abuse, sexual abuse, emotional abuse, or neglect prior to age 18 years., Main Outcomes and Measures: Proportion and number of cases, years of life lost, years lived with disability, and disability-adjusted life-years of mental health conditions (anxiety, depression, harmful alcohol and drug use, self-harm, and suicide attempt) attributable to childhood maltreatment., Results: Meta-analytic estimates were generated from 34 studies and 54 646 participants and applied to prevalence estimates of childhood maltreatment generated from 8503 Australians. Childhood maltreatment accounted for a substantial proportion of mental health conditions, ranging from 21% (95% CI, 13%-28%) for depression to 41% (95% CI, 27%-54%) of suicide attempts. More than 1.8 million cases of depressive, anxiety, and substance use disorders could be prevented if childhood maltreatment was eradicated. Maltreatment accounted for 66 143 years of life lost (95% CI, 43 313-87 314), primarily through suicide, and 184 636 disability-adjusted life-years (95% CI, 109 321-252 887)., Conclusions and Relevance: This study provides the first estimates of the causal contribution of child maltreatment to mental health in Australia. Results highlight the urgency of preventing child maltreatment to reduce the population prevalence and burden of mental disorders.
