Previous research has found that both racism and sexual assault are related to posttraumatic stress disorder (PTSD) symptoms and chronic pain. Black women have unique relationships to these stressors situated within contexts of oppression, and little is known about factors that may exacerbate these associations among Black women. Among Black women experiencing both racism and sexual assault (n = 148), emotion clarity moderated the relation between PTSD and chronic pain, β = .0126, SE  = 0.0059, p  < .05. Our findings support the importance of considering the place that psychological constructs like emotion regulation and traumatic stressors hold in contexts of oppression., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Dissociation is a common response to trauma linked to functional brain disruptions in brain networks subserving emotion regulation and multisensory integration; however, structural neural correlates of dissociation are less known, particularly abnormalities in stress-sensitive white matter (WM) tracts. The present study examined associations between dissociation and WM microstructure, assessed via fractional anisotropy (FA), in a large, diverse sample of women recruited as part of a long-standing trauma study, the Grady Trauma Project (GTP). As part of GTP, 135 trauma-exposed women (18-62 years old, M=34.25, SD=12.96, 84% self-identifying as Black) were recruited, received diffusion tensor imaging, and completed the Multiscale Dissociation Inventory (MDI); FA values were extracted from ten major WM tracts of interest. Partial correlations were conducted to examine associations between dissociation facets (MDI total and subscales) and FA while covarying age and temporal signal-to-noise ratio; false discovery rate corrected p < 0.05 indicated statistical significance. FA in seven tracts showed significant negative associations with overall dissociation (MDI total score; rs<-0.19, p FDR <0.05); the corona radiata, corpus callosum, superior longitudinal fasciculus, thalamic radiation, anterior cingulum, fornix, and uncinate fasciculus. Among facets of dissociation, FA was most consistently associated with dissociative memory disturbance, showing a significant and negative association with all but one of tract of interest, (rs<-0.23, p FDR <0.05). Our findings indicated that dissociation severity was linked to proportionally lesser WM microstructural integrity in tracts involved with sensory integration, emotion regulation, memory, and self-referential processing. Disruptions in these pathways may underlie dissociative phenomena, representing important psychotherapeutic and neuromodulatory targets., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2024 Elsevier B.V.

Importance: Racial discrimination increases the risk of adverse brain health outcomes, potentially via neuroplastic changes in emotion processing networks. The involvement of deep brain regions (brainstem and midbrain) in these responses is unknown. Potential associations of racial discrimination with alterations in deep brain functional connectivity and accelerated epigenetic aging, a process that substantially increases vulnerability to health problems, are also unknown., Objective: To examine associations of racial discrimination with brainstem and midbrain resting-state functional connectivity (RSFC) and DNA methylation age acceleration (DMAA) among Black women in the US., Design, Setting, and Participants: This cohort study was conducted between January 1, 2012, and February 28, 2015, and included a community-based sample of Black women (aged ≥18 years) recruited as part of the Grady Trauma Project. Self-reported racial discrimination was examined in association with seed-to-voxel brain connectivity, including the locus coeruleus (LC), periaqueductal gray (PAG), and superior colliculus (SC); an index of DMAA (Horvath clock) was also evaluated. Posttraumatic stress disorder (PTSD), trauma exposure, and age were used as covariates in statistical models to isolate racial discrimination-related variance. Data analysis was conducted between January 10 and October 30, 2023., Exposure: Varying levels of racial discrimination exposure, other trauma exposure, and posttraumatic stress disorder (PTSD)., Main Outcomes and Measures: Racial discrimination frequency was assessed with the Experiences of Discrimination Scale, other trauma exposure was evaluated with the Traumatic Events Inventory, and current PTSD was evaluated with the PTSD Symptom Scale. Seed-to-voxel functional connectivity analyses were conducted with LC, PAG, and SC seeds. To assess DMAA, the Methylation EPIC BeadChip assay (Illumina) was conducted with whole-blood samples from a subset of 49 participants., Results: This study included 90 Black women, with a mean (SD) age of 38.5 (11.3) years. Greater racial discrimination was associated with greater left LC RSFC to the bilateral precuneus (a region within the default mode network implicated in rumination and reliving of past events; cluster size k = 228; t85 = 4.78; P < .001, false discovery rate-corrected). Significant indirect effects were observed for the left LC-precuneus RSFC on the association between racial discrimination and DMAA (β [SE] = 0.45 [0.16]; 95% CI, 0.12-0.77)., Conclusions and Relevance: In this study, more frequent racial discrimination was associated with proportionately greater RSFC of the LC to the precuneus, and these connectivity alterations were associated with DMAA. These findings suggest that racial discrimination contributes to accelerated biological aging via altered connectivity between the LC and default mode network, increasing vulnerability for brain health problems.

Aggression is a costly public health problem with severe and multi-faceted negative consequences and thus, identifying factors that contribute to aggression, particularly in understudied populations, is necessary to develop more effective interventions to reduce the public health cost of aggression. The goal this study was to test whether difficulties regulating emotions moderated the association between posttraumatic stress disorder (PTSD) symptoms and aggression in a community sample of predominantly Black females with high levels of trauma exposure. Furthermore, we explored unique relations between PTSD symptom clusters and distinct subscales of difficulties regulating emotions and aggression. The sample included 601 community participants recruited from an urban public hospital. Symptoms were assessed using self-report measures including the Difficulties in Emotion Regulation Scale (DERS) and Behavioral Questionnaire-Short. Regression analyses were conducted using PTSD symptoms and total DERS to test their interaction as predictors for aggression (using BQ-Short). We found that higher levels of PTSD arousal symptoms and difficulty controlling impulses when upset were positively related to aggression. We also conducted an exploratory analysis to examine the association between PTSD symptom clusters using the Alternative Symptom Clusters hybrid model. The results suggest that some PTSD symptoms (externalizing behavior) and some emotion dysregulation processes (difficulties controlling impulses when upset), relate to aggression in independent, rather than multiplicative ways. These results offer insights for new directions of research that focuses on the independent association between specific emotion dysregulation processes and PTSD symptoms on aggression., (© 2024 Wiley Periodicals LLC.)

Mindfulness-based cognitive therapy (MBCT) offers promise as a group-based intervention to alleviate posttraumatic stress disorder (PTSD) and depression symptoms in traumatized Black adults. Given the high level of barriers that exist for low-income Black adults, virtual delivery of MBCT may be helpful. This pilot randomized controlled trial assessed feasibility and acceptability of an adapted 8-week virtual MBCT group intervention for Black adults screening positive for PTSD and depression. Forty-six participants (89.3% women) recruited from an urban safety net hospital were randomized to MBCT or waitlist control (WLC). Overall feasibility was fair (70%); however, completion rates were higher for WLC than MBCT (90% vs. 54%). Group acceptability was high across quantitative and qualitative measures for study completers. Perceived barriers to psychological treatment were high (>9). While showing potential via improved coping skills and positive health changes, this intervention's success hinges on mitigating engagement barriers for future delivery; additional studies are warranted.

Background: Mood disorders such as major depressive and bipolar disorders, along with posttraumatic stress disorder (PTSD), schizophrenia (SCZ), and other psychotic disorders, constitute serious mental illnesses (SMI) and often lead to inpatient psychiatric care for adults. Risk factors associated with increased hospitalization rate in SMI (H-SMI) are largely unknown but likely involve a combination of genetic, environmental, and socio-behavioral factors. We performed a genome-wide association study in an African American cohort to identify possible genes associated with hospitalization due to SMI (H-SMI)., Methods: Patients hospitalized for psychiatric disorders (H-SMI; n=690) were compared with demographically matched controls (n=4467). Quality control and imputation of genome-wide data were performed following the Psychiatric Genetic Consortium (PGC)-PTSD guidelines. Imputation of the Human Leukocyte Antigen (HLA) locus was performed using the HIBAG package., Results: Genome-wide association analysis revealed a genome-wide significant association at 6p22.1 locus in the ubiquitin D ( UBD/FAT10 ) gene (rs362514, p=9.43x10 -9 ) and around the HLA locus. Heritability of H-SMI (14.6%) was comparable to other psychiatric disorders (4% to 45%). We observed a nominally significant association with 2 HLA alleles: HLA-A*23:01 (OR=1.04, p=2.3x10 -3 ) and HLA-C*06:02 (OR=1.04, p=1.5x10 -3 ). Two other genes ( VSP13D and TSPAN9 ), possibly associated with immune response, were found to be associated with H-SMI using gene-based analyses., Conclusion: We observed a strong association between H-SMI and a locus that has been consistently and strongly associated with SCZ in multiple studies (6p21.32-p22.1), possibly indicating an involvement of the immune system and the immune response in the development of severe transdiagnostic SMI., Competing Interests: KR has performed scientific consultation for Acer Therapeutics, Bickel, Bionomics, Boehringer Ingelheim, Takeda, and Jazz Pharma; serves on Scientific Advisory Boards for Sage, the Brain Research Foundation, and the National Center for PTSD, he has received sponsored research support from Brains way and Alto Neuroscience.

Background: Dissociative symptoms can emerge after trauma and interfere with attentional control and interoception; disruptions to these processes are barriers to mind-body interventions such as breath-focused mindfulness (BFM). To overcome these barriers, we tested the use of an exteroceptive augmentation to BFM, using vibrations equivalent to the amplitude of the auditory waveform of the actual breath, delivered via a wearable subwoofer in real time (VBFM). We tested whether this device enhanced interoceptive processes, attentional control and autonomic regulation in trauma-exposed women with dissociative symptoms., Methods: 65 women, majority (82%) Black American, aged 18-65 completed self-report measures of interoception and 6 BFM sessions, during which electrocardiographic recordings were taken to derive high-frequency heart rate variability (HRV) estimates. A subset ( n = 31) of participants completed functional MRI at pre- and post-intervention, during which they were administered an affective attentional control task., Results: Compared to those who received BFM only, women who received VBFM demonstrated greater increases in interoception, particularly their ability to trust body signals, increased sustained attention, as well as increased connectivity between nodes of emotion processing and interoceptive networks. Intervention condition moderated the relationship between interoception change and dissociation change, as well as the relationship between dissociation and HRV change., Conclusions: Vibration feedback during breath focus yielded greater improvements in interoception, sustained attention and increased connectivity of emotion processing and interoceptive networks. Augmenting BFM with vibration appears to have considerable effects on interoception, attention and autonomic regulation; it could be used as a monotherapy or to address trauma treatment barriers.

Introduction: Exposure to traumatic events and stressful life experiences are associated with a wide range of adverse mental and physical health outcomes. Studies have found post-traumatic stress disorder (PTSD), depression, and anxiety sensitivity occurrence to be common in addition to inflammatory diseases like asthma, especially in women. Moreover, overlapping neurobiological mechanisms have been linked to both PTSD and asthma., Methods: In the current study, n = 508 women reported on presence of lifetime asthma diagnosis and symptoms of trauma-related psychopathology including PTSD and depression. A separate group of female participants (n = 64) reported on asthma, PTSD, depression and anxiety sensitivity, and underwent functional MRI scans during a fearful faces task, and their anterior insula responses were analyzed., Results: Overall, PTSD and depression severity were significantly higher in those with asthma versus those without asthma. There was a positive association between anterior insula response to social threat cues and depression symptoms only among individuals without a lifetime presence of asthma., Discussion: These findings provide continued evidence on the interactions between stress, neural mechanisms involved in interoception and salience detection, and trauma-related psychopathology., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Objective: Racism is a multifaceted system of oppression that disproportionately harms Black mothers and children across the lifespan. Despite reliable evidence that racism is associated with worse mental health outcomes (eg, increased depressive symptoms), less is known about potential intergenerational effects of Black mothers' experiences of racism on children's mental health, as well as how traumatic experiences influence these pathways. In this cross-sectional quantitative study, we aimed (1) to replicate the finding that maternal experiences of racism are associated with both maternal and child depression; (2) to identify whether maternal experiences of racism are indirectly associated with child depression via the effect of maternal depression; and (3) to test whether the indirect effect of racism on child depression via maternal depression is conditioned on maternal trauma., Method: Black mothers and their children (N = 148 dyads) were recruited from an urban hospital and were interviewed about their experiences of racism, trauma, and mental health symptoms. The mothers' average age was 35.16 years (SD = 8.75) and the children's average age was 10.03 years (SD = 1.51)., Results: First, we found that maternal experiences of racism were associated with more severe maternal depression (r = 0.37, p < .01) as well as more severe child depression (r = 0.19, p = .02). Second, we found that maternal experiences of racism were indirectly associated with child depression through the effect of maternal depression (ab = 0.76, 95% CI = 0.26, 1.37). Third, we found that maternal trauma exposure moderated this indirect effect such that, at relatively lower levels of maternal trauma exposure, the indirect effect of maternal experiences of racism on child depression was nonsignificant (ω low  = -0.05, 95% CI = -0.50, 0.45), whereas at relatively higher levels of maternal trauma exposure, the indirect effect of maternal experiences of racism on child depression was statistically significant (ω high = .65, 95% CI = 0.21, 1.15)., Conclusion: These findings suggest that the indirect effect of maternal experiences of racism on child depression through the effect of maternal depression depends on the degree of maternal trauma exposure. This study advances the literature by shedding light on key processes that can explain the intergenerational effects of racism as well as contextual factors that can exacerbate racism's downstream consequences across generations., (Copyright © 2023 American Academy of Child and Adolescent Psychiatry.

Background: Racial discrimination is consistently associated with adverse health outcomes and has been linked to structural decrements in brain white matter. However, it is unclear whether discrimination-related neuroplastic changes could indirectly affect health outcomes. Our goal was to evaluate indirect associations of racial discrimination on health outcomes through white matter microstructure in a sample of trauma-exposed Black women., Methods: A trauma study in an urban hospital setting recruited 79 Black women who received a history and physical examination to assess medical disorders (compiled into a summed total of disorder types). Participants reported on experiences of racial discrimination and underwent diffusion tensor imaging; fractional anisotropy values were extracted from white matter pathways previously linked to racial discrimination (corpus callosum, including the body and genu; anterior cingulum bundle; and superior longitudinal fasciculus) and entered into mediational models., Results: Indirect effects of racial discrimination on medical disorders through left anterior cingulum bundle fractional anisotropy were significant (β = 0.07, SE = 0.04, 95% CI [0.003, 0.14]) after accounting for trauma and economic disadvantage. Indirect effects of racial discrimination on medical disorders through corpus callosum genu fractional anisotropy were also significant (β = 0.08, SE = 0.04, 95% CI [0.01, 0.16])., Conclusions: Racial discrimination may increase risk for medical disorders via neuroplastic effects on microstructural integrity of stress-sensitive prefrontal white matter tracts. Racial discrimination-related changes in these tracts may affect health behaviors, which, in turn, influence vulnerability for medical disorders. These data highlight the connections between racial discrimination, prefrontal white matter connections, and incidence of medical disorders in Black Americans., (Copyright © 2022 Society of Biological Psychiatry.

Objective: There is support for the use of mindfulness-based approaches with trauma-exposed adults. However, limited data are available on feasibility and acceptability of group-based mindfulness interventions in urban medical clinics serving primarily Black adults with low socioeconomic resources, where rates of trauma exposure are high. The present randomized pilot study evaluated the feasibility and acceptability of an 8-week adapted mindfulness-based cognitive therapy (MBCT) group for trauma-exposed Black adults who screened positive for posttraumatic stress disorder (PTSD) and depression in an urban primary care clinic setting., Method: Participants were randomized to waitlist control (WLC) or MBCT. Feasibility and acceptability were assessed through examination of retention rates, measures of group satisfaction and treatment barriers, and qualitative interview. Forty-two Black adults (85% women) were consented; of those, 34 (81%) completed preassessment and randomization., Results: Feasibility of study design was shown, with > 75% ( n = 26) of randomized participants completing the study through postassessment. Twenty-four individuals (70.5%) completed through 1-month follow-up. Results showed high levels of group acceptability across quantitative and qualitative measures. Perceived barriers to psychological treatment were high, with an average of > 6 barriers present., Conclusions: The findings indicate feasibility and acceptability of MBCT group interventions in urban primary care settings with trauma-exposed patients with significant psychopathology. However, substantial barriers to treatment engagement were endorsed and to improve numbers for successful engagement in the intervention, continued efforts to reduce treatment barriers and increase access to mindfulness-based interventions in underresourced communities are needed.

Background: Stress contributes to premature aging and susceptibility to alcohol use disorder (AUD), and AUD itself is a factor in premature aging; however, the interrelationships of stress, AUD, and premature aging are poorly understood., Methods: We constructed a composite score of stress from 13 stress-related outcomes in a discovery cohort of 317 individuals with AUD and control subjects. We then developed a novel methylation score of stress (MS stress) as a proxy of composite score of stress comprising 211 CpGs selected using a penalized regression model. The effects of MS stress on health outcomes and epigenetic aging were assessed in a sample of 615 patients with AUD and control subjects using epigenetic clocks and DNA methylation-based telomere length. Statistical analysis with an additive model using MS stress and a MS for alcohol consumption (MS alcohol) was conducted. Results were replicated in 2 independent cohorts (Generation Scotland, N = 7028 and the Grady Trauma Project, N = 795)., Results: Composite score of stress and MS stress were strongly associated with heavy alcohol consumption, trauma experience, epigenetic age acceleration (EAA), and shortened DNA methylation-based telomere length in AUD. Together, MS stress and MS alcohol additively showed strong stepwise increases in EAA. Replication analyses showed robust association between MS stress and EAA in the Generation Scotland and Grady Trauma Project cohorts., Conclusions: A methylation-derived score tracking stress exposure is associated with various stress-related phenotypes and EAA. Stress and alcohol have additive effects on aging, offering new insights into the pathophysiology of premature aging in AUD and, potentially, other aspects of gene dysregulation in this disorder., (Published by Elsevier Inc.)

Racial discrimination (RD) has been consistently linked to adverse brain health outcomes. These may be due in part to RD effects on neural networks involved with threat appraisal and regulation; RD has been linked to altered activity in the rostral anterior cingulate cortex (rACC) and structural decrements in the anterior cingulum bundle and hippocampus. In the present study, we examined associations of RD with cingulate, hippocampus and amygdala gray matter morphology in a sample of trauma-exposed Black women. Eighty-one Black women aged 19-62 years were recruited as part of an ongoing study of trauma. Participants completed assessments of RD, trauma exposure, and posttraumatic stress disorder (PTSD), and underwent T1-weighted anatomical imaging. Cortical thickness, surface area and gray matter volume were extracted from subregions of cingulate cortex, and gray matter volume was extracted from amygdala and hippocampus, and entered into partial correlation analyses that included RD and other socio-environmental variables. After correction for multiple comparisons and accounting for variance associated with other stressors and socio-environmental factors, participants with more RD exposure showed proportionally lower cortical thickness in the left rACC, caudal ACC, and posterior cingulate cortex (ps < = 0.01). These findings suggest that greater experiences of RD are linked to compromised cingulate gray matter thickness. In the context of earlier findings indicating that RD produces increased response in threat neurocircuitry, our data suggest that RD may increase vulnerability for brain health problems via cingulate cortex alterations. Further research is needed to elucidate biological mechanisms for these changes., (© 2022. The Author(s), under exclusive licence to American College of Neuropsychopharmacology.)

Background: Prior findings suggest that psychopathology following interpersonal trauma or assaultive violence may present differently from prototypical posttraumatic stress disorder (PTSD). However, whether this is true for sexual trauma (ST) in the context of other salient lifetime traumatic experiences is yet unknown. We predicted that ST exposure may result in higher avoidance and numbing symptoms and blunted fear responses, relative to non-sexual trauma (NST), particularly if ST occurred during childhood., Methods: Participants were n = 5163 Black women recruited in an urban public hospital. We investigated effects of ST on PTSD symptoms, fear-potentiated startle (FPS) response (n = 285), and amygdala reactivity and habituation to social threat cues with fMRI (n = 95)., Results: ST was associated with greater PTSD symptoms (p = 2.64 × 10 -21 ), but this was observed across all symptom clusters. Women who experienced repeated ST in both childhood and adulthood showed greater PTSD (p = .0009) and numbing symptoms (p = .002). In the FPS paradigm, the ST group startled more on all blocks and stimulus types than the NST group (p = .004). Developmental timing of ST did not influence startle magnitude. ST was not associated with amygdala habituation or reactivity., Limitations: Generalizability is limited to Black women with a high trauma burden. Associations are cross-sectional, limiting causal conclusions., Conclusion: While survivors of ST may present with more severe PTSD symptoms, their profiles are not characteristically different from similar NST controls. Childhood sexual abuse exposure alone did not result in a unique symptom profile. ST represents a uniquely high-burden stressor with likelihood for more severe posttraumatic outcomes., Competing Interests: Conflict of interest Dr. Ressler has received consulting fees or sponsored research support from Alkermes, BrainsWay, and Genomind, and he serves on scientific advisory boards for Janssen, Takeda, and Verily.

Parental emotion regulation plays a major role in parent-child interactions, and in turn, neural plasticity in children, particularly during sensitive developmental periods. However, little is known about how parental emotion dysregulation is associated with variation in children's brain structure, which was the goal of this study. Forty-five Black American mother-child dyads were recruited from an intergenerational trauma study; emotion regulation in mothers and their children (age 8-13 years) was assessed. Diffusion-weighted images were collected in children; deterministic tractography was used to reconstruct pathways of relevance to emotion regulation. Metrics of white matter connectivity [fractional anisotropy (FA), mean diffusivity (MD)] were extracted for pathways. Socio-economic variables were also included in statistical models. Maternal emotion dysregulation was the strongest predictor of child fornix MD (r = .35, p = .001), indicating that more severe emotion dysregulation in mothers corresponded with lower fornix connectivity in children. Maternal impulsivity was a strong predictor of child fornix MD (r = .51, p < .001). Maternal emotion dysregulation may adversely influence connectivity of the child.s fornix, a hippocampal-striatal pathway implicated in reward processes; these associations remained even after accounting for other socio-environmental factors. Dysregulated maternal emotions may uniquely impact children's adaptation to trauma/stress by affecting networks that support appetitive processing., (© 2022 Wiley Periodicals LLC.)

Objectives: Parental posttraumatic stress disorder (PTSD) increases children's risk for emotional and behavioral problems. We examined parenting stress and parenting behavior quality as mediators of the relation between maternal PTSD and problematic child behaviors in a sample at high risk for trauma exposure. We also examined whether child sex moderated this association., Method: Participants were 141 African American mother-child dyads (children aged 8-12). Mothers reported PTSD severity, parenting stress, and child behavior (externalizing, internalizing, and emotional self-control). Parenting behavior quality (accounting for factors including parental warmth and engagement) was assessed from an observational parent-child interaction task., Results: Parenting stress, but not observed parenting behavior quality, mediated the relation between maternal PTSD severity and child behaviors. Child sex moderated this association, such that the effect was stronger for girls., Conclusions: Maternal PTSD may be associated with negative child behavior outcomes, and this relation appears to be mediated by increased parenting stress. Stress-reducing interventions for parents with PTSD could improve child outcomes, especially for girls. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Objective: Emotion dysregulation is a transdiagnostic risk factor for many mental health disorders and develops in the context of early trauma exposure. Research suggests intergenerational risk associated with trauma exposure and posttraumatic stress disorder (PTSD), such that maternal trauma experiences and related symptoms can negatively impact child outcomes across development. The goals of the present study were to examine child and mother correlates of child PTSD symptoms and the unique roles of child and maternal emotion dysregulation in understanding child PTSD symptoms., Method: Subjects included 105 African American mother-child dyads from an urban hospital serving primarily low-income minority individuals., Results: Correlational results showed that child trauma exposure, child emotion dysregulation, maternal depressive symptoms, maternal emotion dysregulation, and potential for maternal child abuse all were significantly associated with child PTSD symptoms ( p s < 0.05). Hierarchical linear regression models revealed that child trauma exposure, maternal depression, and maternal abuse potential accounted for 29% of the variance in child PTSD symptoms ( p < 0.001). Both child emotion dysregulation ( R change ² = 0.14, p < .001) and maternal emotion dysregulation ( R change ² = 0.04, p < .05) were significantly associated with child PTSD symptoms independent of other risk factors and potential for maternal abuse was no longer a significant predictor., Conclusions: These results suggest that maternal emotion dysregulation may be an important factor in influencing their child's PTSD symptoms above and beyond child-specific variables. Both maternal and child emotion dysregulation could be valuable treatment targets for improving maternal mental health and parenting behaviors and bolstering child health outcomes, thus reducing intergenerational transmission of risk associated with trauma.

Objective: African Americans living in low-income urban environments are disproportionately exposed to violence compared to other racial groups. Child exposure to community violence is linked to adverse psychological outcomes, including externalizing and internalizing behaviors. Emotion dysregulation may be one psychological process through which externalizing and internalizing behaviors develop in the context of childhood violence exposure. However, limited research exists on how different aspects of emotion dysregulation are affected by community violence exposure in children., Method: The present study examined whether violence exposure was indirectly associated with externalizing and internalizing behaviors via facets of emotion dysregulation in a sample of 94 African American mother-child dyads. Mothers and children completed measures to assess child community violence exposure, externalizing and internalizing behaviors, and emotion dysregulation (anger, sadness, and worry dysregulation)., Results: Results indicated that maternal report of child community violence exposure was indirectly associated with externalizing behaviors via anger dysregulation and internalizing behaviors via worry dysregulation. Child report of community violence exposure was also indirectly associated with externalizing behavior via anger dysregulation; however, there were no significant associations with internalizing behavior., Conclusions: These findings suggest that certain components of emotion dysregulation serve as an indirect pathway of influence for community violence exposure on child behavior, and the pathways differ between externalizing and internalizing behavior outcomes. Emotion dysregulation may serve as an important potential treatment target in reducing long-term risks associated with violence exposure in urban communities of color.

There is debate about the validity of the complex posttraumatic stress disorder (CPTSD) diagnosis and whether disturbances in self-organization (DSO) in CPTSD can be differentiated from borderline personality disorder (BPD). How PTSD is defined may matter. The present study used exploratory structural equation modeling (ESEM) to replicate and extend prior work by including two models to examine how PTSD (ICD-11, DSM-5), DSO, and BPD symptoms relate. Participants (N = 470; 98.1% women; 97.7% Black) were recruited from medical clinics within an urban hospital. PTSD, CPTSD, and BPD were assessed using semi-structured interviews and trauma-related avoidance, aggressive behavior, and anxious attachment were assessed using self-report measures. ESEM models of PTSD, DSO, and BPD symptoms were run. We found a three-factor ESEM model of CPTSD (ICD-11 PTSD and DSO symptoms) and BPD symptoms best fit the data and found support for discriminant validity between factors across trauma-related avoidance, aggressive behavior, and anxious attachment. For DSM-5 PTSD, a two-factor ESEM model was best-fitting (PTSD and DSO/BPD). The findings demonstrate clear distinguishing and overlapping features of ICD-11 PTSD, CPTSD, and BPD and the necessity to consider the diagnostic structure of PTSD in determining the additive value of CPTSD as a distinct construct., (Copyright © 2022 Elsevier Ltd.

Background: Posttraumatic stress disorder (PTSD) is heritable and a potential consequence of exposure to traumatic stress. Evidence suggests that a quantitative approach to PTSD phenotype measurement and incorporation of lifetime trauma exposure (LTE) information could enhance the discovery power of PTSD genome-wide association studies (GWASs)., Methods: A GWAS on PTSD symptoms was performed in 51 cohorts followed by a fixed-effects meta-analysis (N = 182,199 European ancestry participants). A GWAS of LTE burden was performed in the UK Biobank cohort (N = 132,988). Genetic correlations were evaluated with linkage disequilibrium score regression. Multivariate analysis was performed using Multi-Trait Analysis of GWAS. Functional mapping and annotation of leading loci was performed with FUMA. Replication was evaluated using the Million Veteran Program GWAS of PTSD total symptoms., Results: GWASs of PTSD symptoms and LTE burden identified 5 and 6 independent genome-wide significant loci, respectively. There was a 72% genetic correlation between PTSD and LTE. PTSD and LTE showed largely similar patterns of genetic correlation with other traits, albeit with some distinctions. Adjusting PTSD for LTE reduced PTSD heritability by 31%. Multivariate analysis of PTSD and LTE increased the effective sample size of the PTSD GWAS by 20% and identified 4 additional loci. Four of these 9 PTSD loci were independently replicated in the Million Veteran Program., Conclusions: Through using a quantitative trait measure of PTSD, we identified novel risk loci not previously identified using prior case-control analyses. PTSD and LTE have a high genetic overlap that can be leveraged to increase discovery power through multivariate methods., (Copyright © 2021 Society of Biological Psychiatry. All rights reserved.)

Background: Experiences of racial discrimination are linked to a range of negative brain health outcomes, but little is known about how these experiences impact neural architecture, including white matter microstructure, which may partially mediate these outcomes. Our goal was to examine associations between racially discriminatory experiences and white matter structural integrity in a sample of Black American women., Methods: We recruited 116 Black American women as part of a long-standing study of trauma. Participants completed assessments of racial discrimination, trauma exposure, and posttraumatic stress disorder and underwent diffusion tensor imaging. Fractional anisotropy and mean diffusivity values were extracted from major white matter tracts throughout the brain., Results: Experiences of racial discrimination were associated with significantly lower fractional anisotropy in multiple white matter tracts, including the corpus callosum, cingulum, and superior longitudinal fasciculus (ps < .004), even after accounting for variance associated with trauma, posttraumatic stress disorder, and demographic- and scanner-related factors., Conclusions: These findings suggest that experiences of racial discrimination are independently related to decrements in white matter microarchitecture throughout the brain. In individuals who have experienced other types of adversity, racial discrimination clearly has additive and distinctive deleterious effects on white matter structure. Our findings suggest a pathway through which racial discrimination can contribute to brain health disparities in Black Americans; the deleterious contributions of racial discrimination on the microstructure of major white matter pathways may increase vulnerability for the development of neurodegenerative disorders as well as the development of mental health problems., (Copyright © 2021 Society of Biological Psychiatry.

Parenting behavior is key to understanding transmission of intergenerational trauma-related risk. Emotion dysregulation (ED) and psychological symptoms are associated with negative parenting behaviors, although their unique roles remain unclear. The current study examined associations of ED dimensions, depression, PTSD, and substance use with parenting behaviors in African American mothers. Participants included 98 mother-child dyads recruited from an urban hospital setting. Trauma exposure, ED, depression, substance use, and parenting behaviors (overreactivity, laxness, demandingness, warmth, corporal punishment) were assessed using self-report measures. PTSD was assessed using a semi-structured interview. Correlational results showed significant positive associations between ED and dysfunctional parenting behavior ( p < .001), overreactivity ( p < .001), and laxness ( p < .01) and negative associations with warmth ( p < .01). These associations varied across the dimensions of ED examined. Regression analyses were run to examine the unique effects of ED (separate models for overall and specific dimensions) and psychological symptoms; overall ED and its dimensions accounted for significant variance in parental behaviors ( R 2 = .10-.24, p's < .01), while additional model steps including psychological symptoms were not significant except for the association between depression and lower warmth. In efforts to reduce the intergenerational effects of trauma, parenting interventions that include a direct focus on certain dimensions of ED may be critical.

The current study investigated the relationship between trauma exposure and psychopathology in a sample of predominately African-American women of low socioeconomic status (SES). Women (N = 7430) were recruited from medical clinics at two large public hospitals in Atlanta, GA, from 2005 to 2017. Women were assessed for sociodemographics, life-course trauma burden, posttraumatic stress disorder (PTSD), and major depressive disorder (MDD) utilizing self-report and structured clinical interview assessments. The effects of trauma exposure on current and lifetime PTSD and MDD were examined. Ninety-one percent of women reported trauma exposure, 83% reported a monthly household income of less than $2000, and 41% reported a history of arrest. Regarding psychiatric diagnoses, 30.8% met the criteria for probable MDD, and 32.3% met the criteria for probable PTSD. History of childhood abuse and total lifetime trauma significantly increased PTSD and depressive symptoms with additional incremental trauma exposure. PTSD and depressive symptom scores (95% CI) increased from 5.5 (5.0-6.1) and 8.4 (7.9-9.0) in the no trauma group to 20.8 (20.1-21.5) and 20.4 (19.7-21.2), respectively, in those exposed to four or more types of trauma. These results show high rates of adult and childhood trauma exposure, PTSD, MDD, and an additive effect of lifetime trauma exposure on the development of PTSD and MDD in a sample of low SES African-American women. These findings bring light to the high psychiatric symptom burden in this population and call for increased availability of interventions to address symptoms as well as policies aimed at reducing trauma exposure across the lifespan., (© 2021.

Background: Psychological resilience - positive psychological adaptation in the context of adversity - is defined and measured in multiple ways across disciplines. However, little is known about whether definitions capture the same underlying construct and/or share similar correlates. This study examined the congruence of different resilience measures and associations with sociodemographic factors and body mass index (BMI), a key health indicator., Methods: In a cross-sectional sample of 1429 African American adults exposed to child maltreatment, we derived four resilience measures: a self-report scale assessing resiliency (perceived trait resilience); a binary variable defining resilience as low depression and posttraumatic stress (absence of distress); a binary variable defining resilience as low distress and high positive affect (absence of distress plus positive functioning); and a continuous variable reflecting individuals' deviation from distress levels predicted by maltreatment severity (relative resilience). Associations between resilience measures, sociodemographic factors, and BMI were assessed using correlations and regressions., Results: Resilience measures were weakly-to-moderately correlated (0.27-0.69), though similarly patterned across sociodemographic factors. Women showed higher relative resilience, but lower perceived trait resilience than men. Only measures incorporating positive affect or resiliency perceptions were associated with BMI: individuals classified as resilient by absence of distress plus positive functioning had lower BMI than non-resilient (β = -2.10, p = 0.026), as did those with higher perceived trait resilience (β = -0.63, p = 0.046)., Conclusion: Relatively low congruence between resilience measures suggests studies will yield divergent findings about predictors, prevalence, and consequences of resilience. Efforts to clearly define resilience are needed to better understand resilience and inform intervention and prevention efforts.

Posttraumatic stress disorder (PTSD) has a specified precipitant (i.e., trauma), and thus, is particularly well-suited to examine risk and maintenance factors for the development of the disorder. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) alternative model of personality disorder (AMPD) is based, in part, on a dimensional trait model; previous research suggests that personality traits are related to PTSD symptoms. To date, there is little research examining this model with regard to PTSD symptoms, and such research could elucidate new strategies for identification and prevention. The present study investigates associations between AMPD traits and PTSD symptoms in a cross-sectional high-risk sample ( N = 490; 100% female; 97.8% African American) and in a prospective, longitudinal sample of Level 1 trauma center patients ( N = 185; 46.8% female; 72.5% African American). The Personality Inventory for DSM-5 Brief Form domains were significantly associated with PTSD total symptom severity and symptom clusters across both self-report and clinical interview measures. Personality Inventory for DSM-5 Negative Affectivity and Psychoticism emerged as significant predictors of concurrent PTSD. When prospectively predicting PTSD symptoms in the longitudinal cohort, Negative Affectivity and Psychoticism were significant predictors of PTSD symptom severity. These findings indicate how the DSM-5 AMPD pathological traits are associated with risk for stress-related disorders cross-sectionally and prospectively.

Reduced heart rate variability (HRV) in response to stress is a biomarker of emotion dysregulation (ED) and is related to posttraumatic stress disorder (PTSD), yet less is known about its role with dissociation in trauma-exposed adults. The goals of the current study were to examine unique patterns of associations between ED, dissociation, and PTSD with HRV at 15, 30, and 45 min (T1, T2, T3) following an acute psychosocial stressor task in a sample of 49 trauma-exposed, urban-dwelling Black women. Associations with baseline psychophysiology measures were also examined. ED and dissociation were assessed using self-report; PTSD was determined using a semi-structured interview. Heart rate (HR) and HRV, indexed with low frequency/high frequency (LF/HF) ratio and respiratory sinus arrhythmia (RSA), were measured with electrocardiogram recordings. ED and dissociation were positively correlated with LF/HF ratio at T3 (p < .05). There were no significant differences between individuals with PTSD versus those without PTSD in HR or HRV following acute stressor; PTSD diagnosis was related to higher HR at baseline. Latent growth modeling revealed that ED was associated with higher LF/HF ratio directly following acute stressor, while dissociation was associated with increase in LF/HF ratio over time. These findings demonstrate that ED is related to higher sympathetic reactivity for a prolonged period of time following stress exposure, while dissociation shows a delayed association with LF/HF ratio, suggesting a distinct impaired parasympathetic activation pattern exists for dissociation., (Copyright © 2021 Elsevier Ltd.

Background: Moral injury (MI) describes emotional, spiritual, and social suffering that can arise following psychological trauma. Prior research in military pop ulations indicates the relevance of MI to adverse psychological outcomes, such as post-traumatic stress disorder (PTSD) and suicidal behaviours, and shows evidence for MI as a unique construct. Minimal studies of MI have been implemented in civilians, usually restricted to small samples with a specific set of traumatic experiences, despite the conceptual relevance of MI to non-military trauma reactions more broadly (e.g. feelings of betrayal towards a perpetrator of sexual abuse)., Objective: To address this problem, we assessed MI in trauma-exposed civilians to examine ways in which this construct was related to and distinct from trauma and traumatic stress-related problems, including PTSD and depression., Method: We adapted an existing MI scale, Moral Injury Events Scale (MIES) and administered this measure to 81 men and women along with measures of trauma exposure, PTSD and depression, and also asked participants about past suicide attempts., Results: We observed that both greater exposure and distress related to potentially morally injurious events were associated with higher trauma exposure, particularly childhood maltreatment, as well as post-traumatic and depressive psychopathology. However, even after accounting for current PTSD and depression symptoms, MI exposure (F = 6.05, p = .017) was significantly higher among participants who had previously attempted suicide., Conclusions: These pilot data reveal the ways in which MI is associated with trauma exposure, PTSD and depression and highlight the salience of MI in civilians. Similarly, these data demonstrate the unique relevance of MI to suicide behaviours, independent of post-traumatic psychopathology, indicating that this construct may be an understudied contributor to suicide risk in civilians., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2021 The Author(s).

Objectives: Growing evidence of the effectiveness of mindfulness-based interventions for posttraumatic stress disorder (PTSD) warrants greater understanding of factors relevant to the relation between trait mindfulness and PTSD, such as emotion dysregulation (ED). The goal of this study was to examine associations between trait mindfulness, ED, and PTSD symptoms across two samples of trauma-exposed adults., Methods: Participants for Sample 1 ( n = 39, 90% women, 100% Black) and Sample 2 ( n = 60, 100% women, 87% Black) were recruited from an urban hospital in the South. Trait mindfulness, ED, and PTSD were assessed., Results: Across both samples, mindfulness and ED were significantly associated with overall PTSD severity ( r = -.49 and r = -.42, ps = .001; r = .53 and r = .51, ps < .001, respectively) in the expected direction. In Sample 1, mindful nonjudgment and difficulty with emotion regulation strategies showed the strongest associations with overall PTSD severity as well as symptom clusters. In Sample 2, mindful acceptance and all ED dimensions (except non-awareness) showed strong associations with overall PTSD severity and particularly with negative cognitions and mood symptoms. In both samples, ED mediated the association between mindfulness and overall PTSD severity (Sample 1: ab = -.15, 95%CI [-.35, -.02]; Sample 2: ab = -.11, 95%CI [-.22, -.04])., Conclusions: These findings demonstrate the important role of ED in the relation between trait mindfulness and PTSD symptoms among trauma-exposed adults. They highlight the value of examining ED as a mechanism of change in mindfulness-based interventions for PTSD., Clinical Trials Registration Information: Sample 1: NCT03922581, April 22, 2019; NCT03938350, May 6, 2019; Sample 2: NCT02754557, April 28, 2016., Competing Interests: Financial and Non-financial Interests The authors have no relevant financial or non-financial interests to disclose.

Importance: Racial discrimination has a clear impact on health-related outcomes, but little is known about how discriminatory experiences are associated with neural response patterns to emotionally salient cues, which likely mediates these outcomes., Objective: To examine associations of discriminatory experiences with brainwide response to threat-relevant cues in trauma-exposed US Black women as they engage in an attentionally demanding task., Design, Setting, and Participants: A cross-sectional study was conducted from May 1, 2014, to July 1, 2019, among 55 trauma-exposed US Black women to examine associations of racial discrimination experiences with patterns of neural response and behavior to trauma-relevant images in an affective attentional control task. Posttraumatic stress disorder (PTSD) symptoms and trauma exposure were entered as covariates to isolate variance associated with experiences of racial discrimination., Exposures: Varying levels of trauma, PTSD symptoms, and experiences of racial discrimination., Main Outcomes and Measures: Experiences of Discrimination Questionnaire (EOD) (range, 0-9) for count of the number of situations for which each participant reported having unfair treatment for a racial reason. Experiences of trauma and PTSD symptoms were assessed with the Traumatic Events Inventory (TEI) (number of times the person was exposed to trauma; score range, 0-112) and PTSD Symptom Scale (PSS) (score range, 0-51). Response to trauma-relevant vs neutral distractor cues were assessed via functional magnetic resonance imaging during performance of an affective Stroop (attentional control) task. Statistical analyses were conducted at a whole-brain, voxelwise level with familywise error correction., Results: In this study of 55 Black women in the US (mean [SD] age, 37.7 [10.7] years; range, 21-61 years), participants reported a mean (SD) TEI frequency of 33.0 (18.8) and showed moderate levels of current PTSD symptoms (mean [SD] PSS score, 15.4 [12.9]). Mean (SD) EOD scores were 2.35 (2.44) and were moderately correlated with current PTSD symptoms (PSS total: r = 0.36; P=.009) but not with age (r = 0.20; P = .15) or TEI frequency (r = -0.02; P = .89). During attention to trauma-relevant vs neutral images, more experiences of racial discrimination were associated with significantly greater response in nodes of emotion regulation and fear inhibition (ventromedial prefrontal cortex) and visual attention (middle occipital cortex) networks, even after accounting for trauma and severity of PTSD symptoms (brainwide familywise error corrected; r = 0.33 for ventromedial prefrontal cortex; P = .02). Racial discrimination was also associated with affective Stroop task performance; errors on trials with threat-relevant stimuli were negatively correlated with experiences of racial discrimination (r = -0.41; P = .003)., Conclusions and Relevance: These findings suggest that experiences of racial discrimination associate with disproportionately greater response in brain regions associated with emotion regulation and fear inhibition and visual attention. Frequent racism experienced by Black individuals may potentiate attentional and regulatory responses to trauma-relevant stressors and lead to heightened modulation of regulatory resources. This may represent an important neurobiological pathway for race-related health disparities.

Background: Most people will experience a traumatic event in their lifetime, but only a subset (<10%) will develop posttraumatic stress disorder (PTSD)., Objective: To facilitate prevention and intervention of PTSD, it is important to understand how risk and resilience factors interact with one another to explain individual differences in risk for PTSD, especially in underprivileged groups, who often experience greater burden of trauma and PTSD., Method: The current study utilized multiple and moderated regression to examine the relation between childhood maltreatment and adulthood PTSD risk in the context of various attachment patterns and emotion dysregulation in a sample (n = 856) of mostly low-income, African American participants., Results: Moderation analysis indicated that the strongest association between self-reported childhood maltreatment and PTSD symptoms was manifest in participants reporting the highest levels of both attachment anxiety and attachment avoidance (b = 0.22, 95% CI [0.15, 0.29], p < .001), whereas, among those low on both these dimensions (i.e., more securely attached participants), there was no significant association between childhood maltreatment and current PTSD (b = 0.07, 95% CI [-0.01, 0.14], p = .07). Separately, multiple regression predicting current PTSD symptoms revealed an effect size for the two attachment dimensions similar to that of emotion dysregulation, while controlling for childhood maltreatment., Conclusions: These findings suggest more secure attachment may buffer against the deleterious effects of childhood maltreatment, and both attachment difficulties and emotion dysregulation serve as robust correlates of adulthood PTSD., (Copyright © 2021 Elsevier Ltd.

Growing research suggests that posttraumatic stress disorder (PTSD) may be a risk factor for poor cardiovascular health, and yet our understanding of who might be at greatest risk of adverse cardiovascular outcomes after trauma is limited. In this study, we conducted the first examination of the individual and synergistic contributions of PTSD symptoms and blood pressure genetics to continuous blood pressure levels. We harnessed the power of the Psychiatric Genomics Consortium-PTSD Physical Health Working Group and investigated these associations across 11 studies of 72,224 trauma-exposed individuals of European ( n = 70,870) and African ( n = 1,354) ancestry. Genetic contributions to blood pressure were modeled via polygenic scores (PGS) for systolic blood pressure (SBP) and diastolic blood pressure (DBP) that were derived from a prior trans-ethnic blood pressure genome-wide association study (GWAS). Results of trans-ethnic meta-analyses revealed significant main effects of the PGS on blood pressure levels [SBP: β = 2.83, standard error (SE) = 0.06, p < 1E-20; DBP: β = 1.32, SE = 0.04, p < 1E-20]. Significant main effects of PTSD symptoms were also detected for SBP and DBP in trans-ethnic meta-analyses, though there was significant heterogeneity in these results. When including data from the largest contributing study - United Kingdom Biobank - PTSD symptoms were negatively associated with SBP levels (β = -1.46, SE = 0.44, p = 9.8E-4) and positively associated with DBP levels (β = 0.70, SE = 0.26, p = 8.1E-3). However, when excluding the United Kingdom Biobank cohort in trans-ethnic meta-analyses, there was a nominally significant positive association between PTSD symptoms and SBP levels (β = 2.81, SE = 1.13, p = 0.01); no significant association was observed for DBP (β = 0.43, SE = 0.78, p = 0.58). Blood pressure PGS did not significantly moderate the associations between PTSD symptoms and blood pressure levels in meta-analyses. Additional research is needed to better understand the extent to which PTSD is associated with high blood pressure and how genetic as well as contextual factors may play a role in influencing cardiovascular risk., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Sumner, Maihofer, Michopoulos, Rothbaum, Almli, Andreassen, Ashley-Koch, Baker, Beckham, Bradley, Breen, Coleman, Dale, Dennis, Feeny, Franz, Garrett, Gillespie, Guffanti, Hauser, Hemmings, Jovanovic, Kimbrel, Kremen, Lawford, Logue, Lori, Lyons, Maples-Keller, Mavissakalian, McGlinchey, Mehta, Mellor, Milberg, Miller, Morris, Panizzon, Ressler, Risbrough, Rothbaum, Roy-Byrne, Seedat, Smith, Stevens, van den Heuvel, Voisey, Young, Zoellner, PGC-PTSD Physical Health Working Group, Nievergelt and Wolf.)

Objective: A wealth of evidence has linked purpose in life (PiL) to better mental and physical health and healthy aging. Here, the authors aimed to determine important correlates of PiL using a machine learning approach., Methods: Participants were recruited from retirement communities by the Rush Memory and Aging Project and assessed for childhood experience, adulthood sociodemographic factors (e.g., education, income, marital status), lifestyle and health behavior (e.g., cognitively stimulating activities, exercise, social activities, social network size), psychological factors (e.g., depression, loneliness, perceived discrimination, perceived social support), personality traits (e.g., PiL, harm avoidance), and medical conditions. Elastic Net was implemented to identify important correlates of PiL., Results: A total of 1,839 participants were included in our analysis. Among the 23 variables provided to Elastic Net, 10 were identified as important correlates of PiL. In order of decreasing effect size, factors associated with lower PiL were loneliness, harm avoidance, older age, and depressive symptoms, while those associated with greater PiL were perceived social support, more social activities, more years of education, higher income, intact late-life cognitive performance, and more middle-age cognitive activities., Conclusion: Our findings identify potentially important modifiable factors as targets for intervention strategies to enhance PiL., (Published by Elsevier Inc.)

In the current study, we used a sample of predominantly African-American women with high rates of trauma exposure (N = 434) to examine psychometric properties of the Personality Inventory for DSM-5-Brief Form (PID-5-BF). We compared model fit between a model with five correlated latent factors and a higher-order model in which the five latent factors were used to estimate a single "general pathology" factor. Additionally, we computed estimates of internal consistency and domain interrelations and examined indices of convergent/discriminant validity of the PID-5-BF domains by examining their relations to relevant criterion variables. The expected five-factor structure demonstrated good fit indices in a confirmatory factor analysis, and the more parsimonious, higher-order model was retained. Within this higher-order model, the first-order factors accounted for more variance in the criterion variables than the general pathology factor in most instances. The PID-5-BF domains were highly interrelated ( r s = .38 to .66), and convergent/discriminant validity of the domains varied: Negative Affectivity and Detachment generally showed the hypothesized pattern of relations with external criteria, while Antagonism and Disinhibition displayed less consistent and discriminant relations. Results are discussed in terms of the costs and benefits of using brief pathological trait measures in samples characterized by high levels of psychopathology.

A history of childhood trauma has been found to have a robust influence on juvenile delinquency, and evidence suggests that childhood sexual abuse is particularly common among female youth involved in the juvenile justice system. The current study sought to investigate impulsivity as a potential mediator of the relationship between childhood sexual abuse (CSA) and juvenile incarceration amongst a community sample of low-income, urban, African American adult women. Although impulsivity has been studied among justice-involved youth, few studies have examined the influence of impulsivity within the relationship between CSA and juvenile incarceration and no known studies have explored their relationship in community populations of African American women with histories of juvenile incarceration. Results revealed that impulsivity mediated the relationship between CSA and previous juvenile incarceration. As an exploratory analysis, overall emotion dysregulation as well as other facets of emotion dysregulation did not serve as significant mediators in this relationship. These findings suggest that difficulties in impulse control may be one mechanism through which childhood sexual abuse increases risk for juvenile justice system involvement among African American women., Competing Interests: Disclosure of Interest: All authors declare that they have no conflicts to report.

Binge eating in childhood has been linked to adverse future health outcomes. Parental factors, such as parents' emotion regulation and executive functioning, are likely to influence children's self-regulatory behaviors, including eating. Executive functioning describes a range of higher-order cognitive functions such as planning, abstraction, inhibitory control and working memory, which involves the ability to learn, update and manipulate new information while managing distractions. No studies have examined associations between maternal emotion regulation and executive functioning and the child's maladaptive eating patterns, which was the goal of the present study. Forty-eight mother and child pairs completed self-report clinical measures of emotion dysregulation and attentional control, and mothers completed a brief neuropsychological battery, which included executive functioning measures. Child's disordered eating was measured with the Child Binge Eating Disorder Scale. Linear regression results indicated that mother's performance on a working memory task and child's emotion dysregulation was significantly associated with child's binge eating symptoms (R  2  = 0.34). These data, which reveal that maternal executive functioning is associated with self-regulatory behaviors in children, indicate a possible mechanism through which maladaptive eating behaviors may emerge early in development. This relationship merits further exploration in larger-scale prospective intergenerational studies., (Copyright © 2020. Published by Elsevier B.V.)

Background : African Americans experience more severe and chronic posttraumatic stress disorder (PTSD) symptoms compared to other racial groups, and thus it is important to examine factors that are relevant for the aetiology of PTSD in this population. Although racial discrimination has been implicated as an exacerbating factor in the development and maintenance of PTSD, relatively less is known about mechanisms through which this process may occur. Objective : The purpose of this study was to examine one such mechanism, emotion dysregulation, in two independent samples of African American adults. Method : Trauma-exposed participants were recruited in a large, urban community hospital setting (initial sample n = 1,841; replication sample n = 294). In the initial sample, participants completed a unidimensional measure of emotion dysregulation and self-reported PTSD symptoms based on the DSM-IV. In the replication sample, participants completed a multidimensional measure of emotion dysregulation and a diagnostic interview of PTSD symptoms based on the DSM-5. Mediation analyses were used to test our hypotheses. Results : Across both samples, results indicated that racial discrimination was indirectly associated with PTSD symptoms through emotion dysregulation (even when trauma load was added as a covariate). Conclusions : Taken together, these results provide strong evidence that the association between racial discrimination and PTSD symptoms may be partially explained by the association between racial discrimination and worse emotion dysregulation. These findings elucidate the impact of racist incidents on mental health and identify modifiable emotion regulatory processes that can be intervened upon to enhance the psychological and social wellbeing of African Americans., Competing Interests: No potential conflict of interest was reported by the authors., (© 2020 The Author(s).

Childhood maltreatment is consistently associated with poor outcomes. However, few epidemiological studies have examined the association between childhood maltreatment and adult resilience capacity, defined as one's perceived ability to cope successfully with challenges. This study aimed to determine associations between adult resilience capacity and specific types and features of childhood maltreatment. Participants were African American adults recruited from a public urban hospital in Atlanta, GA (N = 1,962) between 2005 and 2013. Childhood maltreatment, including witnessing domestic violence or physical, emotional, and sexual abuse, was assessed retrospectively using the Traumatic Events Inventory. Perceived resilience capacity was assessed using the Connor-Davidson Resilience Scale. Linear regressions were performed assessing the association between resilience capacity and childhood maltreatment exposure in general, as well as specific dimensions of exposure, including type, co-occurrence, and developmental timing, adjusting for covariates. Participants exposed to any maltreatment reported lower resilience capacity than unexposed peers, B = -0.38, SE = 0.04, p < .001. All maltreatment types were negatively associated with resilience capacity, even after adjusting for other lifetime trauma exposure. Only emotional abuse remained significantly associated with resilience capacity after accounting for current psychological distress, B = -0.11, SE = 0.05, p = .022. Maltreatment co-occurrence followed an inverse dose-response relationship with resilience capacity: For each additional maltreatment type, scores decreased by 0.18 units (SD = 0.02), p < .001. Finally, the developmental timing of maltreatment did not reveal any differential influences on resilience capacity. The results suggest that childhood emotional abuse and co-occurrence of maltreatment types may be particularly deleterious to adult resilience capacity., (© 2020 International Society for Traumatic Stress Studies.)

The development of biological markers of aging has primarily focused on adult samples. Epigenetic clocks are a promising tool for measuring biological age that show impressive accuracy across most tissues and age ranges. In adults, deviations from the DNA methylation (DNAm) age prediction are correlated with several age-related phenotypes, such as mortality and frailty. In children, however, fewer such associations have been made, possibly because DNAm changes are more dynamic in pediatric populations as compared to adults. To address this gap, we aimed to develop a highly accurate, noninvasive, biological measure of age specific to pediatric samples using buccal epithelial cell DNAm. We gathered 1,721 genome-wide DNAm profiles from 11 different cohorts of typically developing individuals aged 0 to 20 y old. Elastic net penalized regression was used to select 94 CpG sites from a training dataset ( n = 1,032), with performance assessed in a separate test dataset ( n = 689). DNAm at these 94 CpG sites was highly predictive of age in the test cohort (median absolute error = 0.35 y). The Pediatric-Buccal-Epigenetic (PedBE) clock was characterized in additional cohorts, showcasing the accuracy in longitudinal data, the performance in nonbuccal tissues and adult age ranges, and the association with obstetric outcomes. The PedBE tool for measuring biological age in children might help in understanding the environmental and contextual factors that shape the DNA methylome during child development, and how it, in turn, might relate to child health and disease., Competing Interests: The authors declare no competing interest.

Dysregulated fear conditioned responses have been associated with PTSD in adults, with increased fear-potentiated startle (FPS) serving as a potential intermediate phenotype for PTSD risk. This phenotype has also been associated with stress-related ADCYAP1R1 gene variants in adult women. However, FPS and genotype have not yet been examined during development. The aim of this study was to examine developmental changes in fear conditioning, and to see whether these changes were impacted by genotype and trauma. Differential fear conditioning using FPS was tested in n = 63 children ages 8-13 at two visits (V1, V2) 1 year apart. Startle response was measured using electromyograph recordings of the eyeblink muscle. The rs2267735 SNP of the ADCYAP1R1 gene was extracted from genome-wide (GWAS) analyses. Trauma exposure was assessed using the Violence Exposure Scale-Revised (VEX-R). We found significant Visit by Genotype interactions, with CC genotype increasing FPS from V1 to V2. At V2 there was a Genotype by Violence interaction, with higher FPS in the CC vs G allele groups among those with higher violence exposure (F = 17.46, p = 0.0002). Females with the CC genotype had higher FPS compared to G allele females (F = 12.09, p = 0.002); there were no effects of genotype in males. This study showed Gene × Environment × Development and Gene × Sex effects of ADCYAP1R1 in a high-risk pediatric population. Those with the CC genotype and high levels of violence exposure, as well as females with the CC genotype, showed the greatest conditioned fear responses in adolescence.

Background: Attentional bias is linked to a range of mood disorders, including posttraumatic stress disorder (PTSD). The present study examined attention bias patterns in African American children exposed to trauma, in order to better understand potential risk factors for PTSD., Methods: 31 children (ages 8-14) completed an eye-tracking task to assess gaze bias patterns while viewing pairs of emotional and neutral faces. Trauma exposure and PTSD symptoms were assessed in a subsample of children (n = 24)., Results: Repeated measures analysis of variance (ANOVA) results examining attention bias indices and gender showed greater attention bias toward angry faces than happy faces (p < 0.01) and toward emotional faces in males than females (p < 0.05). Correlational analyses showed attention bias toward angry faces was associated with greater levels of child trauma exposure (p < 0.05). Based on linear regression analysis, child trauma exposure accounted for 17 % of variance in attention bias toward angry versus neutral faces independent of gender or posttraumatic stress symptoms (p < 0.05)., Conclusions: Trauma exposure in children is related to altered attention bias, via enhanced attention towards threatening cues. Results contribute to evidence that males and females may exhibit different attentional patterns. This study highlights the importance of additional research on attention bias patterns and prospective mental health outcomes across gender and through development., (Copyright © 2020 Elsevier B.V.

Objective: Pregnant African American women living in low-income urban communities have high rates of trauma exposure and elevated risk for the development of trauma-related disorders, including posttraumatic stress disorder (PTSD) and depression. Yet, engagement in behavioral health services is lower for African American women than Caucasian women. Limited attention has been given to identifying trauma exposure and PTSD, especially within at-risk communities. The present study examined rates of trauma exposure, PTSD, depression, and behavioral health treatment engagement in an obstetrics/gynecology (OB/GYN) clinic within an urban hospital., Method: The study included 633 pregnant African American women screened within the OB/GYN clinic waiting room; 55 of the women also participated in a subsequent detailed clinical assessment based on eligibility for a separate study of intergenerational risk for trauma and PTSD in African American mother-child dyads., Results: Overall, 98% reported trauma exposure, approximately one third met criteria for probable current PTSD, and one third endorsed moderate-or-severe depression based on self-report measures. Similar levels were found based on clinical assessments in the subsample. While 18% endorsed depression treatment, only 6% received treatment for PTSD. In a subsample of women with whom chart reviews were conducted ( n = 358), 15% endorsed a past psychiatric diagnosis but none shared their PTSD diagnosis with their OB/GYN provider., Conclusion: Results of the current study highlight elevated levels of trauma exposure, PTSD, and depression in low-income, African American pregnant women served by this urban clinic, and demonstrate the need for better identification of trauma-related disorders and appropriate linkage to culturally responsive care especially for PTSD.

Biased processing of threatening stimuli, including attention toward and away from threat, has been implicated in the development and maintenance of PTSD symptoms. Research examining theoretically-derived mechanisms through which dysregulated processing of threat may be associated with PTSD is scarce. Negative affect, a transdiagnostic risk factor for many types of psychopathology, is one potential mechanism that has yet to be examined. Thus, the present study (n = 92) tested the indirect effect of attention bias on PTSD via negative affect using rigorous eye-tracking methodology in a sample of urban-dwelling, trauma-exposed African-American women. We found support for the hypothesis that attention bias toward threat was indirectly associated with PTSD symptoms through increased negative affect. These results suggest that negative affect may be an important etiological process through which attention bias patterns could impact PTSD symptom severity. Implications for psychological and pharmacological therapeutic interventions targeting threat-related attention biases and negative affect are discussed., 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 © 2019 Elsevier B.V.

Childhood maltreatment is highly prevalent and serves as a risk factor for mental and physical disorders. Self-reported childhood maltreatment appears heritable, but the specific genetic influences on this phenotype are largely unknown. The aims of this study were to (1) identify genetic variation associated with self-reported childhood maltreatment, (2) estimate SNP-based heritability (h 2 snp ), (3) assess predictive value of polygenic risk scores (PRS) for childhood maltreatment, and (4) quantify genetic overlap of childhood maltreatment with mental and physical health-related phenotypes, and condition the top hits from our analyses when such overlap is present. Genome-wide association analysis for childhood maltreatment was undertaken, using a discovery sample from the UK Biobank (UKBB) (n = 124,000) and a replication sample from the Psychiatric Genomics Consortium-posttraumatic stress disorder group (PGC-PTSD) (n = 26,290). h 2 snp for childhood maltreatment and genetic correlations with mental/physical health traits were calculated using linkage disequilibrium score regression. PRS was calculated using PRSice and mtCOJO was used to perform conditional analysis. Two genome-wide significant loci associated with childhood maltreatment (rs142346759, p = 4.35 × 10 -8 , FOXP1; rs10262462, p = 3.24 × 10 -8 , FOXP2) were identified in the discovery dataset but were not replicated in PGC-PTSD. h 2 snp for childhood maltreatment was ~6% and the PRS derived from the UKBB was significantly predictive of childhood maltreatment in PGC-PTSD (r 2  = 0.0025; p = 1.8 × 10 -15 ). The most significant genetic correlation of childhood maltreatment was with depressive symptoms (r g  = 0.70, p = 4.65 × 10 -40 ), although we show evidence that our top hits may be specific to childhood maltreatment. This is the first large-scale genetic study to identify specific variants associated with self-reported childhood maltreatment. Speculatively, FOXP genes might influence externalizing traits and so be relevant to childhood maltreatment. Alternatively, these variants may be associated with a greater likelihood of reporting maltreatment. A clearer understanding of the genetic relationships of childhood maltreatment, including particular abuse subtypes, with a range of phenotypes, may ultimately be useful in in developing targeted treatment and prevention strategies.

Objective: Although previous research has demonstrated a link between posttraumatic stress disorder (PTSD) and self-rated health, the role of regulatory processes within this relationship has yet to be fully understood for African American urban populations. The goal of the present study was to determine whether emotion dysregulation mediated the relationship between PTSD diagnosis and self-rated health problems., Method: Data were collected from 446 adult participants (92% female, 97% African American) between the ages of 18 and 65 years who were recruited as part of the Grady Trauma Project, a National Institutes of Health-funded study of risk and resilience factors related to PTSD. Participants were recruited from a public hospital, and interviews included demographic characteristics, self-rating of health, assessment of emotion dysregulation using the Difficulties in Emotion Regulation Scale, and PTSD diagnosis using the Modified PTSD Symptom Scale., Results: Results revealed that emotion dysregulation significantly mediated the relationship between PTSD and self-rated health. Exploratory analyses revealed that specific dimensions of emotion regulation were significant mediators in this relationship. Age, sex, education, marital status, income, and total number of lifetime traumas experienced were controlled for in all analyses., Conclusions: Our findings suggest that emotion dysregulation may play a significant role in the PTSD-health relationship for African Americans. Future research investigating culturally relevant emotion regulation strategies are warranted given likely consequences for both physical and mental health outcomes.
