Background: Electrodermal hyporeactivity has been proposed as a marker of suicidal risk. The EUDOR-A study investigated the prevalence of electrodermal hyporeactivity among patients with depression and its association with attempted and completed suicide. Methods: Between August 2014 and March 2016, 1,573 in- and outpatients with a primary diagnosis of depression (active or remission phase) were recruited at 15 European psychiatric centers. Each patient was followed-up for 1 year. Electrodermal activity was assessed at baseline with the ElectroDermal Orienting Reactivity Test. Data on the sociodemographic characteristics, clinical diagnoses, and treatment of the subjects were also collected. The severity of the depressive symptoms was assessed through the Montgomery–Asberg Depression Rating Scale. Information regarding number, time, and method of suicide attempts was gathered at baseline and at the end of the 1-year follow-up. The same data were collected in case of completed suicide. Results: Hyporeactive patients were shown to be significantly more at risk of suicide attempt compared to reactive patients, both at baseline and follow-up. A sensitivity of 29.86% and a positive predictive value (PPV) of 46.77% were found for attempted suicide at baseline, while a sensitivity of 35.36% and a PPV of 8.92% were found for attempted suicide at follow-up. The sensitivity and PPV for completed suicide were 25.00 and 0.61%, respectively. However, when controlled for suicide attempt at baseline, the association between hyporeactivity and follow-up suicide attempt was no longer significant. The low number of completed suicides did not allow any analysis. [ABSTRACT FROM AUTHOR]

An increased risk of suicide has been reported for psychiatric patients. In several world regions, an underlying psychiatric disorder is reported in up to 90% of people who die from suicide, though this rate seems to be considerably lower in low‐ and middle‐income countries. Major psychiatric conditions associated with suicidality are mood disorders, alcohol and substance use disorders, borderline personality disorder, and schizophrenia. Comorbidity between different disorders is frequently associated with a higher suicide risk. A history of suicide attempts, feelings of hopelessness, impulsivity and aggression, adverse childhood experiences, severe psychopathology, and somatic disorders are common risk factors for suicide among psychiatric patients. Stressful life events and interpersonal problems, including interpersonal violence, are often triggers. A comprehensive and repeated suicide risk assessment represents the first step for effective suicide prevention. Particular attention should be paid during and after hospitalization, with the first days and weeks after discharge representing the most critical period. Pharmacological treatment of mood disorders and schizophrenia has been shown to have an anti‐suicidal effect. A significant reduction of suicidal thoughts and behavior has been reported for cognitive behavioral therapy and dialectical behavior therapy. Brief interventions, including psychoeducation and follow‐ups, are associated with a decrease in suicide deaths. Further development of suicide prevention in psychiatric patients will require a better understanding of additional risk and protective factors, such as the role of a person's decision‐making capacity and social support, the role of spiritual and religious interventions, and the reduction of the treatment gap in mental health care.

Introduction: Suicide is a global mental health problem for people of all ages. While rates of suicide in children and adolescents are reported as lower than those in older populations worldwide, they represent the third leading cause of death in 15–19‐year‐olds. The rates are higher among boys than girls worldwide, though the death rates for girls exceed those for boys in Bangladesh, China, India, and Nepal. There has been a general decrease in adolescent suicide rates over recent decades. However, increases are reported in South East Asia as well as South America over the same time period. Methods: A narrative review method has been used to summarize current knowledge about risk and protective factors for suicide among children and adolescents and to discuss evidence‐based strategy for suicide prevention in this age group. Results: Identified suicide risk and protective factors for children and adolescents largely overlap with those for adults. Nevertheless, developmental characteristics may strengthen the impact of some factors, such as decision‐making style, coping strategies, family and peer relationships, and victimization. The implementation of evidence‐based suicide preventive strategies is needed. Restricting access to lethal means, school‐based awareness and skill training programs, and interventions delivered in clinical and community settings have been proven effective. The effectiveness of gatekeeper training and screening programs in reducing suicidal ideation and behavior is unproven but widely examined in selected settings. Discussion: Since most studies have been conducted in western countries, future research should assess the effectiveness of these promising strategies in different cultural contexts. The use of more rigorous study designs, the use of both short‐ and long‐term follow‐up evaluations, the larger inclusion of individuals belonging to vulnerable groups, the evaluation of online intervention, and the analysis of programs' cost‐effectiveness are also required.

The coronavirus (COVID-19) pandemic presents us with unusual challenges to the global health system and economics. The pandemic may not have an immediate impact on suicide rates, however, given that it is likely to result in a confluence of risk factors for suicide and economic crisis, it is highly possibly that it will lead to increases in suicide rates in the long-run. Elderly persons are more likely to live alone, be socially isolated during COVID-19 and have physical health problems, which are risk factors for suicide. Young children and health professionals may also be population at risk. Isolation, quarantine and the economic crisis that follows may impact mental health significantly. The International Academy of Suicide Research (IASR) is an organization dedicated to promote high standards of research and scholarship in the field of suicidal behaviour to support efforts to prevent suicide globally. This IASR's board position paper gives recommendations for suicide research during the COVID-10 pandemic. Clinical research has to be modified due to COVID-19 shutdown. [ABSTRACT FROM AUTHOR]

Background: Predictions of two different models for suicide attempts (SA) over 12 months, as differentially impacted by specific school‐based suicide prevention interventions, were compared. These were as follows: (a) interpersonal theory (IPTS) and (b) a two‐pathway model, one path associated with externalizing symptoms and continuum of self‐harm behaviors, and the other with internalizing symptoms. Methods: Self‐report questionnaires were completed by 11,110 high school students from ten EU countries enrolled in the Saving and Empowering Young Lives in Europe (SEYLE) study. Baseline measures included perceived burdensomeness, thwarted belongingness from parents and peers, health risk behaviors, self‐injury, suicide ideation (SI), and attempts (SA). SI and SA were reassessed at 12‐month follow‐up. Each model's predictions of SI and SA groups over time (i.e., repeated SA, remitted SA, SA onset, and no SA) were estimated in the no intervention/control group. The superior model was estimated across intervention groups. Results: Interpersonal theory showed better fit compared to the two‐pathway model. In partial agreement with IPTS predictions, parental low belongingness but not peer belongingness or burdensomeness predicted greater likelihood of SI. The likelihood of repeated SA versus no SA was higher among adolescents who reported SI, self‐injury, risk behaviors, and particularly both SI and self‐injury. All three interventions attenuated the combined effect of SI and self‐injury. Youth Aware of Mental Health Program (YAM) additionally decreased the effect of risk behaviors on the likelihood of repeated SA. Conclusions: Interpersonal theory assumptions were partially supported. Perceived interpersonal difficulties with parents were primarily related with SI, and risk behaviors and self‐injury were important predictors of SA. Suicide prevention interventions may be effective by mitigating the hazardous effect of varying self‐harm behaviors and may be further advanced by increasing parental involvement.

Objective: Suicide attempt (SA) is recognized as one of the risk factors for completed suicides. The concealment of this behavior often hinders detection and management of suicide risk. Thus, in this study, we sought to shed light on adolescents' psychosocial processes that could facilitate disclosure of SAs. Specifically, we sought to identify antecedents of adolescent SAs that had not been revealed to significant others.Method: A high school sample) N = 990 (completed a self-report questionnaire tapping psychiatric, personal, and interpersonal characteristics, as well as suicidality, as part of the SEYLE project. Twenty-seven adolescents acknowledged having made an SA without disclosing it to parents or to other significant others. They were compared with 47 adolescents who made SAs that were communicated to others and with a control group of 916 adolescents having no history of suicidal behavior.Results: Compared with disclosures and controls, non-disclosing suicide attempters were characterized by higher levels of suicide ideation, distress, and victimization. Low levels of self-disclosure and parental support were significantly associated with undisclosed SAs.Conclusions: Interpersonal difficulties may be related to loneliness and a thwarted sense of belongingness, which may explain the failure to disclose SAs. Implications related to assessment and prevention are discussed. [ABSTRACT FROM AUTHOR]

Background: The association between bullying victimization and depression, suicide ideation and suicide attempts has been studied mainly in cross‐sectional studies. This study aims to test the bidirectional effect and the chronicity versus sporadic effect of physical, verbal, and relational bullying victimization on suicidal ideation/attempts and depression. Methods: Longitudinal assessments with an interval of 3‐ and 12‐months were performed within a sample of 2,933 adolescents (56.1% females; mean age 14.78, SD = .89) from 10 European countries, participating in the Saving and Empowering Young Lives in Europe (SEYLE) school‐based multicenter control sample. Multilevel Structural Equation Models were used, controlling for sociodemographic variables. Victimization was considered chronic when a student was victimized in the first two time points and sporadic when it was reported only at one point but not in another. Results: Bidirectional prospective association between all types of victimization and depression were found. Among participants, who reported victimization once (but not twice), physical victimization, but not verbal and relational, was associated with later suicidal ideation and attempts. Chronic victimization of any type increased likelihood for later depression compared with sporadic and no‐victimization. Chronic relational victimization increased the likelihood of later suicidal ideation, and chronic physical victimization increased the likelihood for suicidal attempts. Conclusions: The results support the bidirectional effect of victimization and depression and indicate that there are complex longitudinal associations between victimization and suicidal ideation/attempts. Physical victimization may especially carry effect on suicidal risk over time. Interventions should focus on victimization as a cause of distress but also aim to prevent vulnerable adolescents from becoming targets of victimization. [ABSTRACT FROM AUTHOR]

Direct self-injurious behaviour (D-SIB) is associated with suicidal behaviour and suicide risk. It is not known if D-SIB cessation reduces these risks. The aim of this study was to explore trajectories of D-SIB and their prospective influence on suicidal thoughts and behaviour during adolescence. Data ( n = 506; 62.06 % females, 14.53 years) from the Saving and Empowering Young Lives in Europe study were analysed. D-SIB and suicidal thoughts and behaviour were assessed at baseline (T0), 1- (T1) and 2-year follow-up (T2). Onset and maintenance of D-SIB between T0 and T1 were associated with a two to threefold increased odds ratio for suicidal thoughts and behaviour at T2. Suicidal thoughts and behaviour in those terminating D-SIB before T1 were similar compared to those with no life-time history of D-SIB. Late onset and maintenance of D-SIB prospectively indicate risk for suicidal thoughts and behaviour. This is the first study showing that D-SIB cessation reduces later risk for suicidal thoughts and behaviour in adolescence. Suicide prevention efforts should set one focus on reducing adolescent D-SIB. [ABSTRACT FROM AUTHOR]

The article reports on two novel genomic rearragements identified in suicide subjects using array-comparative genomic hybridization (a-CGH). Topics include an investigation of the Wernicke area of the brain of suicide subjects, the identification of monoamino-oxidase A (MAOA) and cathechol-O-methyl transferase (COMT) genes as novel predisposing mechanism in suicidal behavior (SB) pathogenesis, how genomic screening using a-CGH may be used as a diagnostic tool for subjects at risk of SB.

Background: One of the major challenges for research in the field of human aggression is the need to define the role of personality and trait-like dimensions, such as impulsivity and aggressiveness, in predisposing to violent behavior. Aims: 1) To determine whether trait- aggressiveness and impulsivity may be associated with socio-demographic, clinical and crime history variables in a sample of male prisoners; 2) to detect any association of those traits with measures of early traumatic experiences and current resilience traits. Methods: A sample of male prisoners ( n = 1356) underwent the Brown-Goodwin Assessment for Lifetime History of Aggression (BGLHA) and the Barratt Impulsivity Scale (BIS). Axis I psychiatric disorders were also assessed. Early traumatic experiences and psychological resilience were detected respectively by the Childhood Trauma Questionnaire (CTQ) and the Connor-Davidson Resilience Scale (CD-RISC). Two non-linear logistic regression models were performed to test for the best predictors of trait-aggressiveness and impulsivity. Results: Subjects with a history of substance use disorders and self-mutilation reported both higher BGLHA and BIS scores. Axis I disorders and suicide attempts were associated with aggressiveness, but not to impulsivity. A consistent correlation was found between BGLHA scores and early traumatic experiences. Resilience was positively correlated to impulsivity but not to aggressiveness scores. Conclusions: Our results support the view that aggressiveness and impulsivity are two different, albeit related trait-like dimensions of personality, having a different relationship with resilience, and, inferentially, a different impact over the development of psychiatric disorders.

IMPORTANCE: Up to 1 million persons die by suicide annually. However, a lack of risk markers makes suicide risk assessment one of the most difficult areas of clinical practice. OBJECTIVE: To assess psychotic symptoms (attenuated or frank) as a clinical marker of risk for suicide attempt. DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study of 1112 school-based adolescents (aged 13-16 years), assessed at baseline and at 3 and 12 months for self-reported psychopathology, psychotic symptoms, and suicide attempts. MAIN OUTCOMES AND MEASURES: Suicide attempts at the 3- and 12-month follow-up and acute suicide attempts (defined as those occurring in the 2 weeks before an assessment). RESULTS: Of the total sample, 7% reported psychotic symptoms at baseline. Of that subsample, 7% reported a suicide attempt by the 3-month follow-up compared with 1% of the rest of the sample (odds ratio [OR], 10.01; 95% CI, 2.24-45.49), and 20% reported a suicide attempt by the 12-month follow-up compared with 2.5% of the rest of the sample (OR, 11.27; 95% CI, 4.44-28.62). Among adolescents with baseline psychopathology who reported psychotic symptoms, 14% reported a suicide attempt by 3 months (OR, 17.91; 95% CI, 3.61-88.82) and 34% reported a suicide attempt by 12 months (OR, 32.67; 95% CI, 10.42-102.41). Adolescents with psychopathology who reported psychotic symptoms had a nearly 70-fold increased odds of acute suicide attempts (OR, 67.50; 95% CI, 11.41-399.21). Differences were not explained by nonpsychotic psychiatric symptom burden, multimorbidity, or substance use. In a causative model, the population-attributable fraction of suicide attempts would be 56% to 75% for psychotic symptoms. CONCLUSIONS AND RELEVANCE: Adolescents with psychopathology who report psychotic symptoms are at clinical high risk for suicide attempts. More careful clinical assessment of psychotic symptoms (attenuated or frank) in mental health services and better understanding of their pathological significance are urgently needed.

Background: Subthreshold-depression and anxiety have been associated with significant impairments in adults. This study investigates the characteristics of adolescent subthreshold-depression and anxiety with a focus on suicidality, using both categorical and dimensional diagnostic models. Methods: Data were drawn from the Saving and Empowering Young Lives in Europe (SEYLE) study, comprising 12,395 adolescents from 11 countries. Based on self-report, including Beck Depression Inventory-II (BDI-II), Zung Self-Rating Anxiety Scale (SAS), Strengths and Difficulties Questionnaire (SDQ) and Paykel Suicide Scale (PSS) were administered to students. Based on BDI-II, adolescents were divided into three groups: nondepressed, subthreshold-depressed and depressed; based on the SAS, they were divided into nonanxiety, subthreshold-anxiety and anxiety groups. Analyses of Covariance were conducted on SDQ scores to explore psychopathology of the defined groups. Logistic regression analyses were conducted to explore the relationships between functional impairments, suicidality and subthreshold and full syndromes. Results: Thirty-two percent of the adolescents were subthreshold-anxious and 5.8% anxious, 29.2% subthreshold-depressed and 10.5% depressed, with high comorbidity. Mean scores of SDQ of subthreshold-depressed/anxious were significantly higher than the mean scores of the nondepressed/nonanxious groups and significantly lower than those of the depressed/anxious groups. Both subthreshold and threshold-anxiety and depression were related to functional impairment and suicidality. Conclusions: Subthreshold-depression and subthreshold-anxiety are associated with an increased burden of disease and suicide risk. These results highlight the importance of early identification of adolescent subthreshold-depression and anxiety to minimize suicide. Incorporating these subthreshold disorders into a diagnosis could provide a bridge between categorical and dimensional diagnostic models. [ABSTRACT FROM AUTHOR]

Abstract: Objective: We wished to examine whether resilience might be a protective factor in relation to suicidal behavior. Method: To do this resilience was examined in relation to childhood trauma, a well established risk factor for suicidal behavior, in two samples. In a preliminary sample 20 abstinent substance abuse patients who had attempted suicide were matched for age and their score on the Childhood Trauma Questionnaire (CTQ) with 20 substance abuse patients who had never attempted suicide. The two age and CTQ matched attempter (N =20) and non-attempter (N =20) groups were then compared for their scores on the Connor-Davidson Resilience Scale (CD-RISC). In the second sample 166 prisoners who had attempted suicide were matched for age and their scores on the CTQ with 166 prisoners who had never attempted suicide. These two age and CTQ matched attempter (N =166)and non-attempter (N =166) groups were similarly compared for their CD-RISC resilience scores. Results: In the preliminary substance abuse sample, patients who had never attempted suicide (N =20) had significantly higher mean CD-RISC resilience scores than the age and CTQ matched patients who had attempted suicide (N =20). Similarly in the prisoner sample, those who had never attempted suicide (N =166) had significantly higher CD-RISC resilience scores than the age and CTQ matched prisoners who had attempted suicide (N =166). Conclusions: The results from these two studies suggest that resilience may be a protective factor mitigating the risk of suicidal behavior associated with childhood trauma. [Copyright &y& Elsevier]

Abstract: Background and Aims: Childhood trauma is a well recognized risk factor for attempting suicide. However, its relationship to the age of onset of first suicide attempt and the repetition of attempts has been little studied. Methods: One thousand five hundred and fifty-three prisoners underwent a psychiatric interview which included the Brown-Goodwin Lifetime History of Aggression (BGHA) interview. The prisoners completed the Childhood Trauma Questionnaire (CTQ) and the Buss-Durkee Hostility Inventory (BDHI). Results: Two hundred prisoners (12.9%) had a history of attempting suicide. Subjects who had attempted suicide had significantly higher CTQ scores than subjects who had never attempted. Childhood traumas were also significantly associated with the early onset of suicidal behavior, while repeated attempts were predicted by sexual abuse only. Early suicidal behavior was further associated with young age, psychiatric disease, aggressive traits and violent behavior. Early age at onset of suicidal behavior was also associated with repetition of suicide attempts. Repetition of suicide attempt was further associated with other self-injurious behaviors (self-harm). Conclusions: These results confirm that a history of attempting suicide is frequent among prisoners. Childhood trauma is a risk factor not only for suicidal behavior but also for its early onset as is having a psychiatric disorder and aggressive traits. Sexual abuse may increase the risk for multiple attempts, which strongly correlated with age at onset and other self-harm behaviors. [Copyright &y& Elsevier]

Abstract: Insomnia has been associated with suicidality. Prisoners have an increased risk of both insomnia and suicidal behaviour. Therefore, it was decided to examine for a relationship between insomnia and suicidal behaviour in a large group of 1420 prisoners. Prisoners had a semi-structured psychiatric interview, which included the Hamilton Depression Rating Scale (HDRS), and completed the Childhood Trauma Questionnaire, Eysenck Personality Questionnaire, Spielberg Anger Expression Inventory and Connor–Davidson Resilience Scale. It was found that 568 (61.2%) of the prisoners scored in the insomnia cluster of the HDRS and that 183 (12.8%) had attempted suicide. Regression analyses showed that insomnia was significantly and independently associated with a lifetime history of attempting suicide. Insomnia was also significantly related to actual suicidality. After controlling for confounders, axis 1 psychiatric disorder, childhood trauma, neuroticism, low resilience, and anger were significantly associated with insomnia in male prisoners. These data suggest the possibility of a relationship between insomnia and suicidality in prisoners. Assessing insomnia may be helpful when evaluating the risk of suicidality in prisoners.

We wished to examine determinants of suicidal behavior in prisoners. 903 male prisoners had a psychiatric interview which included various psychometric tests. Suicide attempters were compared with prisoners who had never attempted suicide. Significantly more of the attempters had a history of psychiatric disorder, substance abuse, a family history of suicidal behavior, convictions for violent crime, had exhibited aggressive behavior in jail, and had higher BGLHA aggression scores. A similar pattern of risk factors was found for prisoners with suicidal ideation. A lifetime history of attempting suicide, or of having suicidal ideation, is frequent in prisoners. Risk factors include family, developmental, aggression, personality psychiatric, and substance abuse factors. [ABSTRACT FROM AUTHOR]

Introduction: Recent post-mortem studies of suicide victims have implicated brain-derived neurotrophic factor (BDNF) in suicide. Therefore, it was decided to examine the possible role of a gene in the regulation of BDNF activity in relation to suicidal behaviour among depressed patients. Method: A series of 170 depressed patients were evaluated for their history of suicide attempts and genotyped for the BDNF Val66Met polymorphism (SNP ID: rs6265). Depressed patients who had (n = 97) or had not (n = 73) attempted suicide were compared. Results: Depressed patients who carried the BDNF Val66Met polymorphism variant (GA + AA) appeared to show a significantly increased risk of suicidal behaviour. The risk of a suicide attempt was also significantly higher among those reporting higher levels of childhood emotional, physical and sexual abuse. Secondary analyses suggested that depression severity was a significant risk factor only in the wild-type BDNF genotype, and that the risk of suicide attempts was more predictable within the wild-type group. Conclusion: These preliminary data suggest that BDNF may play a role in the suicidal behaviour of depressed patients. Copyright © 2008 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Resilience is an important personality feature that is thought to be protective against the development of psychiatric disorder. However, it appears not to have been previously examined directly in relation to suicidal behavior. Therefore, with the recent development of a resilience scale, the purpose of this preliminary study was to examine resilience in relation to attempting suicide. In order to do this 100 abstinent substance dependent patients were interviewed about whether or not they had ever attempted suicide and completed the Connor-Davidson Resilience Scale. The results showed that patients who had attempted suicide (N = 41) had significantly lower resilience scale scores than patients who had never attempted suicide (N = 59). This suggests the possibility that low resilience may be a risk factor for suicidal behavior. Longitudinal studies among suicide attempters, including measures of depression, may further evaluate the possible relevance of resilience to suicidal behavior. [ABSTRACT FROM AUTHOR]

The article reviews a study on the link between suicide attempts and self-harm among prisoners. Topics discussed are the risk factors for suicide such as violent behavior, psychiatric diagnosis and substance abuse. Study limitations include the low predictive power of the risk factors identified and lack of information about completed suicides after released from jail/prison. Recommendations for further study include the biological predictors of suicide and preventive actions.
