Childhood adversities and post-traumatic stress disorder: evidence for stress sensitisation in the World Mental Health Surveys

Affective Visual Circuit Dysfunction in Trauma and Stress-Related Disorders

Posttraumatic stress disorder (PTSD) is widely recognized as involving disruption of core neurocircuitry that underlies processing, regulation, and response to threat. In particular, the prefrontal cortex-hippocampal-amygdala circuit is a major contributor to posttraumatic dysfunction. However, the functioning of core threat neurocircuitry is partially dependent on sensorial inputs, and previous research has demonstrated that dense, reciprocal connections exist between threat circuits and the ventral visual stream. Furthermore, emergent evidence suggests that trauma exposure and resultant PTSD symptoms are associated with altered structure and function of the ventral visual stream. In the current review, we discuss evidence that both threat and visual circuitry together are an integral part of PTSD pathogenesis. An overview of the relevance of visual processing to PTSD is discussed in the context of both basic and translational research, highlighting the impact of stress on affective visual circuitry. This review further synthesizes emergent literature to suggest potential timing-dependent effects of traumatic stress on threat and visual circuits that may contribute to PTSD development. We conclude with recommendations for future research to move the field toward a more complete understanding of PTSD neurobiology.

The Role of Functional Health Literacy in Terms of Hazardous Alcohol Use in Adults with Probable Posttraumatic Stress Disorder and Alcohol Use Disorder

Objective: Co-occurring posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) represents a prevalent and problematic comorbidity. Functional health literacy (FHL) may play a role in this comorbidity based on its previously documented role in hazardous drinking. The current study examined functional health literacy (FHL) regarding hazardous drinking among a sample with probable posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD). Methods: The current study is a secondary analysis of data from a project studying the transdiagnostic risk and maintenance factors of PTSD and hazardous alcohol use among people with probable PTSD and AUD. Participants were 565 nationally recruited adults with probable PTSD and hazardous alcohol use (52.2% female, 68.8% non-Hispanic White, average age = 39.2 years ± 10.9 years). Linear regression models were conducted regressing hazardous alcohol use onto PTSD symptoms and FHL scores. An interaction term between FHL and PTSD symptoms was included in the regression models with age, biological sex, race, and income included as covariates. Results: Low FHL maintained a statistically significant role in predicting greater hazardous drinking (p < .001) even in the context of posttraumatic stress. High posttraumatic stress also emerged as a statistically significant predictor of hazardous alcohol use (p < .001). The interaction term between FHL and PTSD was not found to be a significant predictor of hazardous alcohol use (p = .222). Conclusion: FHL may be a relevant variable for better understand hazardous drinking among persons with comorbid PTSD and AUD.

The association between childhood adversity and hippocampal volumes is moderated by romantic relationship experiences

Reduced hippocampal volumes are a feature of many mental disorders. Childhood maltreatment is a known risk factor for the development of psychopathology and has consistently been linked to hippocampal volume reductions in adults, but not in children and adolescents. We propose that maltreatment-related difficulties in coping with developmental tasks in adolescence and young adulthood might underlie the delayed emergence of hippocampal volume reductions in maltreated individuals. In a study with 196 healthy young adults (mean age [years]: 24.0 ± 3.2, 50% female, 20.6% living with a partner (missings: n = 2)), we investigated the interaction between childhood maltreatment (Childhood Trauma Screener) and the breakup of a steady romantic relationship (List of Threatening Experiences Questionnaire) on hippocampal magnetic resonance imaging grey matter volumes. The experience of a romantic relationship breakup moderated the association between childhood maltreatment and bilateral hippocampal volumes, revealing more negative associations with hippocampal volumes in participants with at least one breakup compared to those with no breakup experience (right hippocampus: β = - 0.05 ± 0.02, p = 0.031, p (FDR) = 0.031; left hippocampus: β = -0.06 ± 0.02, p = 0.005, p (FDR) = 0.009). Moreover, our findings provide some evidence that childhood maltreatment is related to smaller bilateral hippocampal volumes only in those adults who suffered from a relationship breakup (right hippocampus: β = -0.23 ± 0.10, p = 0.018, p (FDR) = 0.018; left hippocampus: β = -0.24 ± 0.10, p = 0.016, p (FDR) = 0.018;). Our study highlights the interaction of adult social bonds with early adversity on vulnerability to psychopathology.

Brain connectivity disruptions in PTSD related to early adversity: a multimodal neuroimaging study

Background: Post-traumatic stress disorder (PTSD) is increasingly prevalent in individuals with adverse childhood experiences (ACE). However, the underlying neurobiology of ACE-related PTSD remains unclear.Objective: The present study investigated the brain connectivity in ACE-related PTSD using multimodal neuroimaging data.Methods: Using a total of 119 participants with ACE (70 with ACE-related PTSD and 49 ACE-exposed controls), this study acquired T1-weighted MRI, diffusion-weighted MRI, and resting-state fMRI data to examine structural and functional connectivity between groups. Joint connectivity matrix independent component analysis (Jcm-ICA) was employed to allow shared information from all modalities to be examined and assess structural and functional connectivity differences between groups.Results: Jcm-ICA revealed distinct connectivity alterations in key brain regions involved in cognitive control, self-referential processing, and social behaviour. Compared to controls, the PTSD group exhibited functional hyperconnectivity of the right medial prefrontal cortex (PFC) of the default mode network and right inferior temporal cortex, and functional hypoconnectivity in the lateral-PFC of the central executive network and structural hypoconnectivity in white matter pathways including the right orbitofrontal region (OFC) linked to social behaviour. Post-hoc analyses using the joint brain-based information revealed that the severity of ACE, the number of traumas, and PTSD symptoms later in life significantly predicted the effects of ACE-related PTSD on the brain. Notably, no direct association between brain connectivity alterations and PTSD symptoms or the number of traumas within the PTSD group was observed.Conclusion: This study offers novel insights into the neurobiology of ACE-related PTSD using multimodal data fusion. We identified alterations in key brain networks (DMN, CEN) and OFC, suggesting potential deficits in cognitive control and social behaviour alongside heightened emotional processing in individuals with PTSD. Furthermore, our findings highlight the combined influence of ACE exposure, number of traumas experienced, and PTSD severity on brain connectivity disruptions, potentially informing future interventions.

Self-compassion as a protective factor against post-traumatic stress symptoms induced by adverse childhood experiences: A cross-sectional study among Japan air self-defense force new recruits

Adverse childhood experiences (ACEs) may result in long-term mental health complications, including post-traumatic stress disorder (PTSD). ACEs are known to be more frequent among military personnel, despite their need to maintain their mental health to accomplish their missions. Self-compassion, or treating oneself with kindness and understanding, can mitigate the psychological effects of adversity but is also affected by adversity. This cross-sectional study aimed to identify the complex relationships between ACEs, self-compassion, and PTSD symptoms among 752 new recruits of the Japan Air Self-Defense Force, of whom 537 with ACEs completed the PTSD Checklist for DSM-5. Hierarchical multiple regression analysis was used to examine the independent effect of self-compassion, measured using the Self-Compassion Scale, on PTSD symptoms. Mediation effect analysis with self-compassion as a mediator was conducted on the relationship between ACEs and PTSD symptoms. We confirmed high levels of ACEs among our participants compared to a healthy population of a previous study, and approximately 6% presented PTSD symptoms above a threshold. Self-compassion was significantly negatively associated with PTSD symptoms (β = -.22, 95% confidence interval [CI], -.34 to -.11). Mediation effect analysis revealed that self-compassion partially mediated the relationship between ACEs and PTSD symptoms, explaining 6.9% of this effect, and ACEs were negatively associated with self-compassion (β = -.13, 95% CI, -.22 to -.04). These findings suggested that self-compassion is a protective factor against PTSD symptoms, whereas ACEs can decrease self-compassion. Further research should explore educational interventions to enhance self-compassion among individuals with ACEs to mitigate PTSD symptoms.

Behavioural profiling following acute stress uncovers associations with future stress sensitivity and past childhood abuse

Background: Individuals greatly differ in their responses to acute stress, ranging from resilience to vulnerability that may yield stress-related psychopathology. Stress-related psychopathologies involve, by definition, substantial modifications across multiple behavioural domains, including impaired cognitive, affective and social functioning. Nevertheless, and despite extensive investigation of individual variability in stress responsivity, no study to date simultaneously assessed the impact of acute stress across multiple behavioural domains within a given individual.Objective: To address this critical gap, 84 healthy female participants (mean age 24.45 ± 3.02, range 19-35) underwent an established acute stress induction procedure and completed three behavioural tasks, probing the functional domains of positive, cognitive and social processing, both before and after the acute stress procedure.Method: A novel behavioural profiling algorithm was implemented to identify individuals whose performance was substantially impacted by stress across all three functional domains.Results: Approximately 30% of participants exhibited substantial deviation in their performance from before to after stress in all three tasks, hereon defined as stress-affected. Stress-affected participants did not differ in their psychological and physiological responses to the acute stress procedure from the other stress-unaffected 70% of the sample. However, follow-up assessments in 66 of these participants revealed higher levels of stress six months following the procedure among the stress-affected compared to the stress-unaffected group. Stress-affected individuals also reported more aversive childhood experiences, such that the odds of participants who were sexually abused at an early age to be affected behaviourally by acute stress later in life increased by more than five-fold.Conclusions: Taken together, these findings suggest that being affected by acute stress across multiple functional domains is associated with future stress sensitivity and past childhood sexual abuse. Probing individual differences in the impact of acute stress across domains of functionality may better align with the multi-dimensional nature of stress responsivity, uncovering latent vulnerability.

Childhood adversity and time to pregnancy in a preconception cohort

We examined the association between childhood adversity and fecundability (the per-cycle probability of conception), and the extent to which childhood social support modified this association. We used data from 6318 female participants aged 21-45 years in Pregnancy Study Online (PRESTO), a North American prospective preconception cohort study (2013-2022). Participants completed a baseline questionnaire, bimonthly follow-up questionnaires (until pregnancy or a censoring event), and a supplemental questionnaire on experiences across the life course including adverse childhood experiences (ACEs) and social support (using the modified Berkman-Syme Social Network Index [SNI]). We used proportional probabilities regression models to compute fecundability ratios (FRs) and 95% CIs, adjusting for potential confounders and precision variables. Adjusted FRs for ACE scores 1-3 and ≥4 vs 0 were 0.91 (95% CI, 0.85-0.97) and 0.84 (95% CI, 0.77-0.91), respectively. The FRs for ACE scores ≥4 vs 0 were 0.86 (95% CI, 0.78-0.94) among participants reporting high childhood social support (SNI ≥4) and 0.78 (95% CI, 0.56-1.07) among participants reporting low childhood social support (SNI <4). Our findings confirm results from 2 previous studies and indicate that high childhood social support slightly buffered the effects of childhood adversity on fecundability.

Dissociation as a mediator of interpersonal trauma and depression: adulthood versus childhood interpersonal traumas3

Extensive research has established that interpersonal trauma is related to depression and dissociation severity. Extending prior research, this study found that childhood and adulthood interpersonal traumas are related to depressive symptoms and examined the role of dissociative process as a mediator. Two hundred eighty-nine adult participants retrospectively reported on traumatic experiences and current symptoms of dissociation and depression, indicating that both childhood and adulthood interpersonal traumas are related to the severity of depression. However, childhood interpersonal trauma was associated with a higher level of dissociative symptoms. Moreover, it was suggested that dissociation serves as a pathway through which childhood interpersonal trauma influences depression, although this relationship was not observed for adulthood interpersonal trauma. In conclusion, this study highlights the potential role of dissociation in the development and maintenance of depression, particularly among individuals who have experienced childhood interpersonal trauma. These findings suggest that interventions targeting dissociation show potential for mitigating retrospective depression, especially for survivors of childhood interpersonal trauma.

Interaction of Val66Met Brain-Derived Neurotrophic Factor and 5-HTTLPR Serotonin Transporter Gene Polymorphisms with Lifetime Prevalence of Post-Traumatic Stress Disorder in Primary Care Patients

Background/Objectives: Post-traumatic stress disorder (PTSD) is a complex condition influenced by both genetic and environmental factors. This longitudinal study aimed to explore the connection between two specific genetic polymorphisms, Val66Met and 5-HTTLPR, and the lifetime prevalence of PTSD in patients from primary care settings. We also examined the role of sociodemographic and psychosocial factors to provide a more comprehensive view of PTSD risk. Methods: We recruited a cohort of primary care patients and diagnosed PTSD using a standardized diagnostic interview. Genetic analyses focused on Val66Met and 5-HTTLPR polymorphisms. We applied logistic regression to assess the association between these genetic markers and PTSD, considering factors such as gender, family history of depression, and experiences of childhood maltreatment. Results: Our findings show that women, individuals with a family history of depression, and those exposed to childhood maltreatment have a higher risk of developing PTSD. While the Val66Met polymorphism was not significantly associated with PTSD, the 5-HTTLPR polymorphism showed a marginal relationship. No significant interaction was found between the two polymorphisms in relation to PTSD. Conclusions: This study underscores the multifactorial nature of PTSD, influenced by both genetic and environmental factors. The findings point to the importance of further research on genetic predispositions and highlight the value of early interventions for high-risk populations in primary care settings.

A nationally representative survey of ICD-11 PTSD among Danish adolescents and young adults aged 15-29

Posttraumatic stress disorder (PTSD) is recognized as a debilitating psychiatric disorder affecting populations worldwide. This has inspired many countries to estimate the national prevalence rates of PTSD in Europe and beyond. At present, there are no published representative studies that have assessed the occurrence of trauma exposure and PTSD in Denmark using a valid measurement based on ICD-11 criteria. A national sample of the general population of young Danish residents, ranging in age between 15 to 29 years (n = 2,434), was surveyed cross-sectionally from April to October 2022. Data weights were applied to ensure representativity of the sample. Multiple regression was used to study the relationship between trauma exposure, sex, age, and PTSD. Accidents and violence were the most common types of trauma exposure with females being more likely to experience sexual violence. A total of 7.7% endorsed probable PTSD with women reporting higher rates of clinical and subclinical PTSD (12.3% and 12.7%, respectively) than men (3.5% and 7.3%, respectively). Findings from the multiple regression showed that female gender was associated with higher PTSD-severity, although the strongest predictor was trauma-type with other types of traumas, and sexual violence displaying the strongest relationship to PTSD-severity overall. A dose-response relationship between the number of trauma types and PTSD symptomatology was found. This is the first study of PTSD in a nationally representative Danish sample using a valid measure of ICD-11 PTSD. The identified PTSD rates were higher than Danish official estimates in a representative sample of the Danish adolescent and young adult population (7.7% weighted compared to 1%). The study replicated international findings of sex differences in probable PTSD endorsement.

Childhood maltreatment and outcomes following electroconvulsive therapy in adults with depression

OBJECTIVE

Childhood maltreatment is associated with less favourable treatment outcomes with pharmacotherapy and psychotherapy for depression. It is unknown whether this increased risk of treatment resistance in maltreated individuals extends to electroconvulsive therapy (ECT).

METHODS

This retrospective cohort study included 501 consecutive adult referrals for an acute course of twice-weekly ECT for unipolar or bipolar depression at an academic inpatient centre in Ireland between 2016 and 2024. Retrospectively reported physical and sexual childhood maltreatment were assessed on hospital admission. Response was defined as a score of 1 or 2 and remission was defined as a score of 1 on the Clinical Global Impression - Improvement scale 1-3 days after final ECT session. Logistic regression analyses were used to examine the associations between childhood maltreatment and ECT nonresponse and nonremission, adjusting for covariates. Mediation analyses were conducted to explore the role of psychiatric comorbidities, persistent depressive symptoms lasting 2 years or more in the current episode, and baseline depression severity.

RESULTS

Compared to the group with no childhood maltreatment, the childhood maltreatment group had similar odds of ECT nonresponse (adjusted odds ratio = 1.47, 95% CI = 0.85-2.53) but significantly elevated odds of ECT nonremission (adjusted odds ratio = 3.75, 95% CI = 1.80-7.81). In a mediation analysis, presence of persistent depressive symptoms mediated 7.4% of the total effect of childhood maltreatment on ECT nonremission.

CONCLUSION

Individuals with exposure to childhood maltreatment may be less likely to achieve full remission following a course of ECT.

Posttraumatic stress disorder following childhood sexual and physical abuse: a study protocol for an 11-week randomised controlled trial comparing imaginal exposure and imagery rescripting

Background: There is a vast amount of evidence supporting the effectiveness of trauma-focused cognitive-behavioral therapy in treating posttraumatic stress disorder (PTSD). However, it remains unclear which specific treatment is most effective for patients with PTSD following childhood sexual and physical abuse (CSPA). Although Imaginal Exposure (IE) has proven highly effective in treating PTSD and is widely acknowledged as a standard method, Imagery Rescripting (IR) may be more suitable for CSPA-related PTSD. IR not only addresses fear but also targets other emotions and cognitions associated with childhood maladaptive schemas. Preliminary findings suggest lower drop-out rates for IR compared to IE, but no Randomized Controlled Trial (RCT) currently assesses the effectiveness of IR for CSPA-related PTSD.Objective: This article presents a study protocol designed to investigate the optimal treatment (IE or IR) for individuals with CSPA-related PTSD and explore predictors of treatment success.Method: In our study protocol, we suggest the inclusion of 173 patients (N = 64 in IR, N = 64 in IE, and N = 45 in the waitlist condition). The therapy procedures for both IE and IR will consist of 16 sessions lasting 90 min each, with treatment durations of 11 weeks. Measurements take place at baseline, at start of treatment, 11 weeks after the start of treatment (after 16 sessions) and at follow-up at 26 weeks after the last session. A mixed regression will be used to compare the three active conditions before and after measurement.Results: This article serves as a study protocol. The results are not yet available but they will be presented in a subsequent article.Conclusion: This study protocol outlines a RCT which will be the first to provide information on the effectiveness of IR versus IE versus a control group in CSPA-related PTSD.Trial registration: Netherlands Trial Register NTR 4817.

Pathways between adverse childhood experiences and viral suppression among male HIV-infected adolescents in South Africa

Fewer adolescents achieve viral suppression compared to adults. One impediment may be a history of adverse childhood experiences (ACEs). To better develop targets and timeframes for intervention, this study created more robust estimates of the impact of cumulative adversity on viral suppression, tested whether the association is sensitive to the timing of adversity, and simultaneously tested several potential mechanisms. We focus on males, who have lower viral suppression than females and who may contribute to disproportionate incidence among young women. We recruited 251 male perinatally HIV-infected adolescents aged 15-19 from HIV clinics in Soweto, South Africa. Adversity was captured using the Adverse Childhood Experience - International Questionnaire (ACE-IQ). Viral load was measured using blood samples; viral suppression was defined as <20 copies/mL. Indicators of medication adherence, depression, post-traumatic stress disorder (, and substance misuse were captured. A series of pathway analysis were performed. Our sample experienced a median of 7 lifetime and 4 past-year adversities. Less than half (44%) exhibited viral suppression. Adversity demonstrated a significant association with suppression; depression mediated the association. Primary prevention of adversity among children living with HIV is paramount, as is addressing the subsequent mental and behavioral health challenges that impede viral suppression among adolescents.

Childhood trauma and hair cortisol response over the year following onset of a chronic life event stressor

OBJECTIVE

Childhood trauma may contribute to poor lifelong health in part through programming of the HPA-axis response to future life stressors. To date, empirical evidence shows an association of childhood trauma with dysregulation of the HPA-axis and blunted cortisol reactivity to acute stressors. Here, we conduct an initial examination of childhood trauma as a moderator of changes over time in perceived stress levels and HPA-axis response to a major chronic stressor in adulthood.

METHODS

Participants were 83 maternal caregivers of children newly diagnosed with cancer who completed the Childhood Trauma Questionnaire (CTQ), and who, over the year following their child's cancer diagnosis, had hair samples collected up to 7 times for the assessment of cortisol and completed monthly measures of perceived stress.

RESULTS

CTQ scores were in the expected range for a community sample and associated with changes in perceived stress and cortisol concentration over time (γ =.003, p =.002; γ = -.0004, p =.008, respectively) independently of age, education, treatment intensity and randomization to stress management intervention. Maternal caregivers who endorsed lower childhood trauma showed a steeper decline in perceived stress and a larger increase in cortisol levels across the year than caregivers who recalled more childhood trauma.

CONCLUSIONS

Findings extend animal models and studies that examine cortisol reactivity to acute stressors and suggest that childhood trauma may program a phenotype that is more psychologically reactive but shows a blunted HPA-axis response to chronic stress. While adaptive in the short-term, this early life programming may incur long-term costs for health. Further work is warranted to examine this possibility.

Adverse Childhood Experiences and Adult Mental Health Outcomes

Importance

Exposure to adverse childhood experiences (ACEs) has consistently been associated with multiple negative mental health outcomes extending into adulthood. However, given that ACEs and psychiatric disorders cluster within families, it remains to be comprehensively assessed to what extent familial confounding contributes to associations between ACEs and clinically confirmed adult psychiatric disorders.

Objective

To investigate whether associations between ACEs and adult mental health outcomes remain after adjusting for familial (genetic and environmental) confounding.

Design, Setting, and Participants

This Swedish twin cohort study used a discordant twin pair design based on monozygotic (MZ) and dizygotic (DZ) twins. A total of 25 252 adult twins (aged 18-47 years) from the Swedish Twin Registry born between 1959 and 1998 were followed up from age 19 years until 2016, with a maximum follow-up time of 39 years. Data were analyzed from April 2022 to November 2023.

Exposures

A total of 7 ACEs, including family violence, emotional abuse or neglect, physical neglect, physical abuse, sexual abuse, rape, and hate crime, were assessed with items from the Life Stressor Checklist-Revised in a web-based survey.

Main Outcomes and Measures

Adult (ages >18 years) clinical diagnosis of psychiatric disorders (ie, depressive, anxiety, alcohol or drug misuse, or stress-related disorders) were obtained from the Swedish National Patient Register.

Results

Of 25 252 twins included in the study (15 038 female [59.6%]; mean [SD] age at ACE assessment, 29.9 [8.7] years), 9751 individuals (38.6%) reported exposure to at least 1 ACE. A greater number of ACEs was associated with increased odds of any psychiatric disorder in the full cohort (odds ratio [OR] per additional ACE, 1.52; 95% CI, 1.48-1.57). The association remained but ORs per additional ACE were attenuated in DZ (1.29; 95% CI, 1.14-1.47) and MZ (1.20; 95% CI, 1.02-1.40) twin pairs. Individuals who were exposed to sexual abuse compared with those who were not exposed had increased odds of any clinically confirmed psychiatric disorder in all comparisons: full cohort (OR, 3.09; 95% CI, 2.68-3.56), DZ twin pairs (OR, 2.10; 95% CI, 1.33-3.32), and MZ twin pairs (1.80; 95% CI, 1.04-3.11).

Conclusions and relevance

This study found that associations between ACEs and adult mental health outcomes remained after controlling for shared genetic and environmental factors, which was particularly evident after multiple ACEs or sexual abuse. These findings suggest that targeted interventions may be associated with reduced risks of future psychopathology.

The Role of Functional Health Literacy in terms of Harmful Alcohol Use in Adults with Probable Posttraumatic Stress Disorder and Alcohol Use Disorder

Purpose

The current study examined functional health literacy (FHL) in regard to hazardous drinking among a sample with probable posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD).

Methods

Participants were 565 adults with probable PTSD and hazardous alcohol use (52.2% female, 68.8% Non-Hispanic White, average age = 39.2 years ± 10.9 years).

Results

FHL literacy maintained statistically significant role in terms of hazardous drinking (p < .001) even in the context of posttraumatic stress.

Conclusion

FHL may be important to better understand hazardous drinking among persons with comorbid PTSD and AUD.

Parental separation and death during childhood as predictors of adult psychopathology: An examination of racial differences

OBJECTIVE

Parental separation and parental death during childhood are common but understudied forms of adverse childhood events (ACEs), thus little is known about the impact on psychological functioning in adulthood. We examined whether parental death and parental separation during childhood was associated with risk of diagnostic criteria for depressive disorders, anxiety disorders, posttraumatic stress disorder (PTSD), or personality disorders during adulthood. Second, we compared parental separation and parental death and psychopathology across African Americans (N = 499) and Whites (N = 782).

METHOD

The sample consists of 1,211 participants (n = 669 females). Diagnostic interviews were administered by master's or doctorate-level degree holders in Clinical Psychology or Social Work. There was good to excellent interrater reliabilities (mean kappa of .84 ± .05; range: .79-.93) spanning anxiety, mood, anxiety, trauma, and personality disorders.

RESULTS

White participants reporting parental separation during childhood were more likely to report depressive disorders (OR = 2.151, p < .001), PTSD (OR = 2.218, p < .01) and personality disorders (OR = 1.764, p < .001) during adulthood. African American endorsement of parental separation during childhood did not predict depressive disorders (OR = 1.21, p = .357), anxiety disorders (OR = 1.107, p = .659), PTSD (OR = 1.351, p = .425) or personality disorders (OR = 1.432, p = .098) during adulthood. Overall, participants who reported parental death did not have significantly higher rates of depressive disorders (OR = 1.100, p = .668), anxiety disorders (OR = 1.357, p = .207), PTSD (OR = 1.351, p = .425), and personality disorders (OR = 1.432, p = .098).

CONCLUSIONS

Parental separation was a significant risk factor for adult psychopathology, but only for White participants. Parental death was not a risk factor for adult psychopathology no matter the person's race. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Early-life stress triggers long-lasting organismal resilience and longevity via tetraspanin

Early-life stress experiences can produce lasting impacts on organismal adaptation and fitness. How transient stress elicits memory-like physiological effects is largely unknown. Here, we show that early-life thermal stress strongly up-regulates tsp-1, a gene encoding the conserved transmembrane tetraspanin in C. elegans. TSP-1 forms prominent multimers and stable web-like structures critical for membrane barrier functions in adults and during aging. Increased TSP-1 abundance persists even after transient early-life heat stress. Such regulation requires CBP-1, a histone acetyltransferase that facilitates initial tsp-1 transcription. Tetraspanin webs form regular membrane structures and mediate resilience-promoting effects of early-life thermal stress. Gain-of-function TSP-1 confers marked C. elegans longevity extension and thermal resilience in human cells. Together, our results reveal a cellular mechanism by which early-life thermal stress produces long-lasting memory-like impact on organismal resilience and longevity.

Self-esteem buffers the stress sensitizing effect of childhood maltreatment on adolescent nonsuicidal self-injury

BACKGROUND

Adversity in childhood increases the risk of psychopathology, perhaps by influencing sensitivity to recent stressful life events (SLEs). However, little is known about the stress-sensitizing effect of childhood adversity on nonsuicidal self-injury (NSSI), whether stress sensitization exists in specific types of SLEs, and the stress-buffering effect of self-esteem. This study aimed to investigate whether exposure to child maltreatment increases adolescent's vulnerability to the effects of dependent and independent SLEs on later NSSI and whether self-esteem buffers this risk.

METHODS

We conducted a two-wave study with 18-month intervals. 601 Chinese adolescents completed self-report measures of child maltreatment, SLEs, self-esteem, and NSSI.

RESULTS

Results supported the stress sensitization hypothesis for child maltreatment regarding dependent SLEs, with dependent SLEs significantly predicting later NSSI only in maltreated adolescents. Moreover, self-esteem buffered the relationship between dependent SLEs and NSSI in maltreated adolescents but amplified the relationship in non-maltreated adolescents. In the maltreated group, dependent SLEs predicted increased NSSI only in those with low self-esteem. In contrast, in the control group, dependent SLEs were significantly associated with NSSI in individuals with high self-esteem.

LIMITATIONS

We did not collect information on the timing of exposure to child maltreatment. Future studies that assess child maltreatment during critical periods of development may be able to identify sensitive period in which maltreatment sensitizes individuals to stress in adolescents.

CONCLUSION

Findings provide preliminary evidence that child maltreatment has a stress-sensitizing effect on adolescent NSSI. Improving self-esteem may mitigate the associations between SLEs and NSSI in adolescents exposed to child maltreatment.

Do Adverse Childhood Experiences Modify the Association Between Disaster-Related Trauma and Cognitive Disability?

Identifying subpopulations that are particularly vulnerable to long-term adverse health consequences of disaster-related trauma is needed. We examined whether adverse childhood experiences (ACEs) potentiate the association between disaster-related trauma and subsequent cognitive disability among older adult disaster survivors. Data were from a prospective cohort study of older adults who survived the 2011 Great East Japan Earthquake. The baseline survey pre-dated the disaster by 7 months. We included participants who completed follow-up surveys (2013 and 2016) and did not have a cognitive disability before the disaster (n = 602). Disaster-related traumas (i.e., home loss, loss of friends or pets) and ACEs were retrospectively assessed in 2013. Cognitive disability levels in 2016 were objectively assessed. After adjusting for pre-disaster characteristics using a machine learning-based estimation approach, home loss (0.19, 95% confidence interval (CI): 0.09, 0.28) was, on average, associated with greater cognitive disability. Among individuals with ACEs, home loss was associated with even higher cognitive disability levels (0.64, 95% CI: 0.24, 1.03). Losses of friends (0.18, 95% CI: 0.05, 0.32) and pets (0.13, 95% CI: 0.02, 0.25) were associated with higher cognitive disability levels only among those with ACEs. Our findings suggest that individuals with a history of ACEs may be particularly vulnerable to adverse health consequences related to disasters.

Treatment of Posttraumatic Stress Disorder: A State-of-the-art Review

This narrative state-of-the-art review paper describes the progress in the understanding and treatment of Posttraumatic Stress Disorder (PTSD). Over the last four decades, the scientific landscape has matured, with many interdisciplinary contributions to understanding its diagnosis, etiology, and epidemiology. Advances in genetics, neurobiology, stress pathophysiology, and brain imaging have made it apparent that chronic PTSD is a systemic disorder with high allostatic load. The current state of PTSD treatment includes a wide variety of pharmacological and psychotherapeutic approaches, of which many are evidence-based. However, the myriad challenges inherent in the disorder, such as individual and systemic barriers to good treatment outcome, comorbidity, emotional dysregulation, suicidality, dissociation, substance use, and trauma-related guilt and shame, often render treatment response suboptimal. These challenges are discussed as drivers for emerging novel treatment approaches, including early interventions in the Golden Hours, pharmacological and psychotherapeutic interventions, medication augmentation interventions, the use of psychedelics, as well as interventions targeting the brain and nervous system. All of this aims to improve symptom relief and clinical outcomes. Finally, a phase orientation to treatment is recognized as a tool to strategize treatment of the disorder, and position interventions in step with the progression of the pathophysiology. Revisions to guidelines and systems of care will be needed to incorporate innovative treatments as evidence emerges and they become mainstream. This generation is well-positioned to address the devastating and often chronic disabling impact of traumatic stress events through holistic, cutting-edge clinical efforts and interdisciplinary research.

Early childhood SARS experience leads to long-lasting impacts on adulthood mental health in China

The association between pandemic experience and immediate mental health risks, such as depression, is well-documented, yet the long-term effects remain unclear. This study examines the impact of early childhood exposure to the 2003 SARS pandemic on adulthood mental health after 17 years in China, using data from the 2020 China Family Panel Studies (CFPS). The analysis included 6289 participants, aged 3 to 30 years during the SARS outbreak, with an average age of 35.3 years at the time of survey. Adulthood mental health was assessed using Center for Epidemiologic Studies Depression Scale (CESD) and an indicator of clinical depression. The severity of local SARS outbreaks was assessed by cumulative cases per 10,000 population. Results show that each additional case per 10,000 population was linked to a 1.617-fold (95% confidence interval (CI): 1.425-1.836) increase in odds of depression after 17 years for younger children (aged 3-12 years in 2003) relative to older cohorts (aged 13-30). This risk was higher in children from rural areas (adjusted odds ratio (aOR) 3.64; 95% CI 2.92-4.55), with poor physical health (1.98; 1.59-2.48), and from low-income families (2.87; 2.03-4.05). The childhood pandemic experience elevated the probability of developing depression-prone personality traits, which contributes to the enduring impact of childhood pandemic experiences on adulthood mental health. These findings highlight the long-lasting psychological impact of early-childhood pandemic exposure, underscoring the need for targeted interventions to mitigate its effects on the younger generation and emphasizing the importance of monitoring long-term mental health and personality development in children post-pandemics, particularly in light of COVID-19.

Early-life stress triggers long-lasting organismal resilience and longevity via tetraspanin

Early-life stress experiences can produce lasting impacts on organismal adaptation and fitness. How transient stress elicits memory-like physiological effects is largely unknown. Here we show that early-life thermal stress strongly up-regulates tsp-1, a gene encoding the conserved transmembrane tetraspanin in C. elegans. TSP-1 forms prominent multimers and stable web-like structures critical for membrane barrier functions in adults and during aging. The up-regulation of TSP-1 persists even after transient early-life stress. Such regulation requires CBP-1, a histone acetyl-transferase that facilitates initial tsp-1 transcription. Tetraspanin webs form regular membrane structures and mediate resilience-promoting effects of early-life thermal stress. Gain-of-function TSP-1 confers marked C. elegans longevity extension and thermal resilience in human cells. Together, our results reveal a cellular mechanism by which early-life thermal stress produces long-lasting memory-like impact on organismal resilience and longevity.

The Effectiveness of Psychological Interventions on the Impact of Trauma Exposure in Foster Care: A Meta-Analysis

Due to prevalent exposure to trauma in the biological family, children in foster care often experience post-traumatic stress symptoms, difficulties in forming secure attachments with the caregivers, and can present a complex range of symptoms and impairments across several areas of development. Therefore, there is an increased necessity for interventions on the effects of trauma exposure in foster care. This is the first meta-analysis to investigate the effectiveness of interventions on the effects of trauma exposure in foster care against control groups. Twelve randomized controlled trials on interventions for children with trauma-related diagnoses or with other mental health problems that are a result of complex trauma were included. A random-effects model was used for pooling the effect sizes, which were calculated for trauma-related outcomes at posttreatment and follow-up. Several potential moderator variables were analyzed. The results showed that participants receiving the intervention on trauma-related problems reported significantly better outcomes than those in the control conditions at posttreatment, after the exclusion of one outlier (g = 0.39; 95% CI [0.18 to 0.62]). The effect size was smaller at follow-up (g = 0.24; 95% CI [0.03 to 0.46]), but significant. Clinical diversity, methodological diversity, as well as other limitations were identified and discussed. Overall, the findings highlight the potential of interventions for trauma-related problems in foster care. These findings bring important contributions to the child welfare system in their efforts to develop and adapt suitable interventions for children with mental health problems due to trauma.

Childhood adversity during the post-apartheid transition and COVID-19 stress independently predict adult PTSD risk in urban South Africa: A biocultural analysis of the stress sensitization hypothesis

OBJECTIVES

The COVID-19 pandemic in South Africa introduced new societal adversities and mental health threats in a country where one in three individuals are expected to develop a psychiatric condition sometime in their life. Scientists have suggested that psychosocial stress and trauma during childhood may increase one's vulnerability to the mental health consequences of future stressors-a process known as stress sensitization. This prospective analysis assessed whether childhood adversity experienced among South African children across the first 18 years of life, coinciding with the post-apartheid transition, exacerbates the mental health impacts of psychosocial stress experienced during the 2019 coronavirus (COVID-19) pandemic (ca. 2020-2021).

MATERIALS AND METHODS

Data came from 88 adults who participated in a follow-up study of a longitudinal birth cohort study in Soweto, South Africa. Childhood adversity and COVID-19 psychosocial stress were assessed as primary predictors of adult PTSD risk, and an interaction term between childhood adversity and COVID-19 stress was calculated to evaluate the potential effect of stress sensitization.

RESULTS

Fifty-six percent of adults exhibited moderate-to-severe PTSD symptoms. Greater childhood adversity and higher COVID-19 psychosocial stress independently predicted worse post-traumatic stress disorder symptoms in adults. Adults who reported greater childhood adversity exhibited non-significantly worse PTSD symptoms from COVID-19 psychosocial stress.

DISCUSSION

These results highlight the deleterious mental health effects of both childhood trauma and COVID-19 psychosocial stress in our sample and emphasize the need for greater and more accessible mental health support as the pandemic progresses in South Africa.

Individual and Social Risk and Protective Factors as Predictors of Trajectories of Post-traumatic Stress Symptoms in Adolescents

The present study elucidates heterogeneity in post-traumatic stress symptoms (PTSS) across adolescence in a sample of youth who have experienced myriad types and combinations of potentially traumatic events (PTEs), including substantiated physical abuse, sexual abuse, neglect and/or at least one other self-reported PTE. A machine learning technique was used to assess a multivariate set of variables (e.g., PTEs, individual risk and protective factors, social risk and protective factors, and racial and ethnic minority status) as predictors of PTSS trajectory group membership. The sample included 498 maltreated (n = 275) and comparison (n = 223) 14-19-year-old female adolescents (M = 15.27, SD = 1.06 at Time 1) assessed annually until age 19. 45.7% of participants were White, 45.3% Black, 0.4% Native American, 0.8% Hispanic, and 7.7% other. Growth mixture modeling identified three distinct trajectories of PTSS: (1) recovery (56%); (2) moderate, chronic (25%); and (3) high, chronic (19%). An elastic net model was used to test predictors of membership in the recovery versus the high, chronic PTSS trajectory groups. Results demonstrated that the recovery trajectory was characterized by the absence of sexual abuse, physical abuse, and other traumas, higher self-esteem, less affective dysregulation, less risky peers, lower levels of parent depression, and being of racial/ethnic minority status. Findings help to characterize individual variation in trajectories of PTSS following PTEs by underscoring the unique trauma responses of racial and ethnic minority youth and offering possible targets of interventions to promote recovery from PTSS.

Risk factors for traumatic bonding and associations with PTSD symptoms: A moderated mediation

BACKGROUND

Traumatic bonding, defined as attachment to a perpetrator of intimate partner violence (IPV), offers one explanation as to why many people with abusive romantic partners do not break off these relationships. But what individual-level risk factors make some victims of IPV more likely than others to develop traumatic bonding toward their partners? What is the nature of the potential association between traumatic bonding and PTSD symptoms?

PARTICIPANTS

A path model tested the potential roles of childhood maltreatment and attachment insecurity as risk factors for traumatic bonding, as well as the potential association between traumatic bonding and PTSD symptoms, in a high-risk sample of 354 participants in current abusive relationships.

RESULTS

As hypothesized, childhood maltreatment and attachment insecurity significantly predicted traumatic bonding over and above the effects of age, gender, and romantic love. In addition, attachment insecurity moderated the association between childhood maltreatment and traumatic bonding, such that at higher levels of attachment insecurity, the association between childhood maltreatment and traumatic bonding was stronger than at mean or lower levels of attachment insecurity. Traumatic bonding was positively associated with PTSD symptoms.

CONCLUSIONS

Overall, the results support the role of childhood maltreatment as a risk factor for both traumatic bonding and PTSD symptoms and highlight the importance of attachment insecurity in these associations. This was the first study to examine a complex model of risk factors for traumatic bonding. Theoretical and clinical implications are discussed.

Interaction of Val66Met BDNF and 5-HTTLPR polymorphisms with prevalence of post-earthquake 27-F PTSD in Chilean population

Post-traumatic stress (PTSD) disorder is a mental health condition that can occur after experiencing or witnessing a traumatic event. The 27-F earthquake that struck Chile in 2010 was one such event that had a significant impact on the mental health of the population. A study was conducted to investigate the prevalence of PTSD and its associated factors among survivors of this earthquake. The study was a longitudinal design, involving a sample of 913 patients aged 18 to 75 years who attended 10 Primary Care Centers in Concepción, Chile. The Composite International Diagnostic Interview (CIDI) was used to assess both depressive episodes (DE) and PTSD before and after the earthquake. The study also involved genotyping studies using saliva samples from the participants, specifically focusing on the Val66Met and 5-HTTLPR polymorphisms. Statistical analysis was performed to examine the association between different variables and the presence of PTSD. These variables included demographic factors, family history of psychiatric disorders, DE, childhood maltreatment experiences, and critical traumatic events related to the earthquake. The results showed that the incidence of post-earthquake PTSD was 11.06%. No significant differences were found between the groups of participants who developed post-earthquake PTSD regarding the Val66Met or 5-HTTLPR polymorphisms. However, a significant association was found between the concomitant diagnosis of DE and the development of post-earthquake PTSD. The presence of DE doubled the risk of developing post-earthquake PTSD. The number of traumatic events experienced also had a statistically significant association with an increased risk of developing post-earthquake PTSD. The study's limitations include the potential interference of different DE subtypes, the complexity of quantifying the degree of earthquake exposure experienced by each individual, and events entailing social disruption, such as looting, that can profoundly influence distress. In conclusion, the study found that PTSD following the 27-F earthquake in Chile was associated with a concomitant diagnosis of DE and the number of traumatic events experienced. The study did not find a significant association between PTSD and the Val66Met or 5-HTTLPR polymorphisms. The researchers recommend that mental health professionals should prioritize the detection and treatment of concomitant depressive episodes and exposure to critical traumatic events in survivors of disasters. They also suggest that further research is needed to better understand the relationship between genetic factors and post-disaster PTSD.

From childhood adversity to latent stress vulnerability in adulthood: the mediating roles of sleep disturbances and HPA axis dysfunction

Childhood adversity is a prominent predisposing risk factor for latent stress vulnerability, expressed as an elevated likelihood of developing stress-related psychopathology upon subsequent exposure to trauma in adulthood. Sleep disturbances have emerged as one of the most pronounced maladaptive behavioral outcomes of childhood adversity and are also a highly prevalent core feature of stress-related psychopathology, including post-traumatic stress disorder (PTSD). After reviewing the extensive literature supporting these claims, the current review addresses the notion that childhood adversity-induced sleep disturbances may play a causal role in elevating individuals' stress vulnerability in adulthood. Corroborating this, sleep disturbances that predate adult trauma exposure have been associated with an increased likelihood of developing stress-related psychopathology post-exposure. Furthermore, novel empirical evidence suggests that sleep disturbances, including irregularity of the sleep-wake cycle, mediate the link between childhood adversity and stress vulnerability in adulthood. We also discuss cognitive and behavioral mechanisms through which such a cascade may evolve, highlighting the putative role of impaired memory consolidation and fear extinction. Next, we present evidence to support the contribution of the hypothalamic-pituitary-adrenal (HPA) axis to these associations, stemming from its critical role in stress and sleep regulatory pathways. Childhood adversity may yield bi-directional effects within the HPA stress and sleep axes in which sleep disturbances and HPA axis dysfunction reinforce each other, leading to elevated stress vulnerability. To conclude, we postulate a conceptual path model from childhood adversity to latent stress vulnerability in adulthood and discuss the potential clinical implications of these notions, while highlighting directions for future research.

A Mendelian randomization study of genetic liability to post-traumatic stress disorder and risk of ischemic stroke

Observational studies have shown an association between post-traumatic stress disorder (PTSD) and ischemic stroke (IS) but given the susceptibility to confounding it is unclear if these associations represent causal effects. Mendelian randomization (MR) facilitates causal inference that is robust to the influence of confounding. Using two sample MR, we investigated the causal effect of genetic liability to PTSD on IS risk. Ancestry-specific genetic instruments of PTSD and four quantitative sub-phenotypes of PTSD, including hyperarousal, avoidance, re-experiencing, and total symptom severity score (PCL-Total) were obtained from the Million Veteran Programme (MVP) using a threshold P value (P) of <5 × 10-7, clumping distance of 1000 kilobase (Mb) and r2 < 0.01. Genetic association estimates for IS were obtained from the MEGASTROKE consortium (Ncases = 34,217, Ncontrols = 406,111) for European ancestry individuals and from the Consortium of Minority Population Genome-Wide Association Studies of Stroke (COMPASS) (Ncases = 3734, Ncontrols = 18,317) for African ancestry individuals. We used the inverse-variance weighted (IVW) approach as the main analysis and performed MR-Egger and the weighted median methods as pleiotropy-robust sensitivity analyses. In European ancestry individuals, we found evidence of an association between genetic liability to PTSD avoidance, and PCL-Total and increased IS risk (odds ratio (OR)1.04, 95% Confidence Interval (CI) 1.007-1.077, P = 0.017 for avoidance and (OR 1.02, 95% CI 1.010-1.040, P = 7.6 × 10-4 for PCL total). In African ancestry individuals, we found evidence of an association between genetically liability to PCL-Total and reduced IS risk (OR 0.95 (95% CI 0.923-0.991, P = 0.01) and hyperarousal (OR 0.83 (95% CI 0.691-0.991, P = 0.039) but no association was observed for PTSD case-control, avoidance, or re-experiencing. Similar estimates were obtained with MR sensitivity analyses. Our findings suggest that specific sub-phenotypes of PTSD, such as hyperarousal, avoidance, PCL total, may have a causal effect on people of European and African ancestry's risk of IS. This shows that the molecular mechanisms behind the relationship between IS and PTSD may be connected to symptoms of hyperarousal and avoidance. To clarify the precise biological mechanisms involved and how they may vary between populations, more research is required.

Biomarkers of Neurodegeneration in Post-Traumatic Stress Disorder: An Integrative Review

Post-Traumatic Stress Disorder (PTSD) is a chronic psychiatric disorder that occurs following exposure to traumatic events. Recent evidence suggests that PTSD may be a risk factor for the development of subsequent neurodegenerative disorders, including Alzheimer's dementia and Parkinson's disease. Identification of biomarkers known to be associated with neurodegeneration in patients with PTSD would shed light on the pathophysiological mechanisms linking these disorders and would also help in the development of preventive strategies for neurodegenerative disorders in PTSD. With this background, the PubMed and Scopus databases were searched for studies designed to identify biomarkers that could be associated with an increased risk of neurodegenerative disorders in patients with PTSD. Out of a total of 342 citations retrieved, 29 studies were identified for inclusion in the review. The results of these studies suggest that biomarkers such as cerebral cortical thinning, disrupted white matter integrity, specific genetic polymorphisms, immune-inflammatory alterations, vitamin D deficiency, metabolic syndrome, and objectively documented parasomnias are significantly associated with PTSD and may predict an increased risk of subsequent neurodegenerative disorders. The biological mechanisms underlying these changes, and the interactions between them, are also explored. Though requiring replication, these findings highlight a number of biological pathways that plausibly link PTSD with neurodegenerative disorders and suggest potentially valuable avenues for prevention and early intervention.

Investigating the relationship between early life adversity, inflammation and alcohol use

Early life adversity (ELA) has long-lasting and potentially harmful effects on adult mental and physical health, including a higher likelihood of developing psychiatric conditions such as depression, anxiety and alcohol use disorder (AUD). It has been suggested that inflammation may play a role in linking ELA to the development of AUD. Here, we evaluated a number of predictive factors of high sensitivity C-reactive protein (hsCRP), a key inflammatory marker, and the potential mediating role of hsCRP in the relationship between ELA and alcohol misuse in adulthood. Data was collected from participants who participated in NIAAA screening protocols between January 2013 and December 2019. In this secondary analysis, we first tested, via multiple linear regression, potential predictors of hsCRP levels among adults with AUD (N = 781) and non-AUD (N = 440) individuals. We subsequently conducted mediation analyses to evaluate the potential role of hsCRP in the relationship between early life stress and alcohol use. Regression analysis showed that stress in early life, but not childhood trauma, significantly predicted increased hsCRP levels in adulthood (p < 0.05). Additionally, a greater amount of alcohol drinking, but not a diagnosis of AUD, significantly predicted increased hsCRP levels (p < 0.05). Furthermore, hsCRP mediated the relationship between early life stress and alcohol consumption. Early life stress and heavier alcohol drinking both predicted increased hsCRP levels; however, an AUD diagnosis did not. Elevated inflammation, due to and/or predicted by greater early life stress, may contribute to the development of unhealthy alcohol use in adulthood.

Prior differences in previous trauma exposure primarily drive the observed racial/ethnic differences in posttrauma depression and anxiety following a recent trauma

BACKGROUND

Racial and ethnic groups in the USA differ in the prevalence of posttraumatic stress disorder (PTSD). Recent research however has not observed consistent racial/ethnic differences in posttraumatic stress in the early aftermath of trauma, suggesting that such differences in chronic PTSD rates may be related to differences in recovery over time.

METHODS

As part of the multisite, longitudinal AURORA study, we investigated racial/ethnic differences in PTSD and related outcomes within 3 months after trauma. Participants (n = 930) were recruited from emergency departments across the USA and provided periodic (2 weeks, 8 weeks, and 3 months after trauma) self-report assessments of PTSD, depression, dissociation, anxiety, and resilience. Linear models were completed to investigate racial/ethnic differences in posttraumatic dysfunction with subsequent follow-up models assessing potential effects of prior life stressors.

RESULTS

Racial/ethnic groups did not differ in symptoms over time; however, Black participants showed reduced posttraumatic depression and anxiety symptoms overall compared to Hispanic participants and White participants. Racial/ethnic differences were not attenuated after accounting for differences in sociodemographic factors. However, racial/ethnic differences in depression and anxiety were no longer significant after accounting for greater prior trauma exposure and childhood emotional abuse in White participants.

CONCLUSIONS

The present findings suggest prior differences in previous trauma exposure partially mediate the observed racial/ethnic differences in posttraumatic depression and anxiety symptoms following a recent trauma. Our findings further demonstrate that racial/ethnic groups show similar rates of symptom recovery over time. Future work utilizing longer time-scale data is needed to elucidate potential racial/ethnic differences in long-term symptom trajectories.

Association of early life stress and cognitive performance in patients with schizophrenia and healthy controls

As core symptoms of schizophrenia, cognitive deficits contribute substantially to poor outcomes. Early life stress (ELS) can negatively affect cognition in patients with schizophrenia and healthy controls, but the exact nature of the mediating factors is unclear. Therefore, we investigated how ELS, education, and symptom burden are related to cognitive performance. The sample comprised 215 patients with schizophrenia (age, 42.9 ± 12.0 years; 66.0 % male) and 197 healthy controls (age, 38.5 ± 16.4 years; 39.3 % male) from the PsyCourse Study. ELS was assessed with the Childhood Trauma Screener (CTS). We used analyses of covariance and correlation analyses to investigate the association of total ELS load and ELS subtypes with cognitive performance. ELS was reported by 52.1 % of patients and 24.9 % of controls. Independent of ELS, cognitive performance on neuropsychological tests was lower in patients than controls (p < 0.001). ELS load was more closely associated with neurocognitive deficits (cognitive composite score) in controls (r = -0.305, p < 0.001) than in patients (r = -0.163, p = 0.033). Moreover, the higher the ELS load, the more cognitive deficits were found in controls (r = -0.200, p = 0.006), while in patients, this correlation was not significant after adjusting for PANSS. ELS load was more strongly associated with cognitive deficits in healthy controls than in patients. In patients, disease-related positive and negative symptoms may mask the effects of ELS-related cognitive deficits. ELS subtypes were associated with impairments in various cognitive domains. Cognitive deficits appear to be mediated through higher symptom burden and lower educational level.

The link between post-traumatic stress disorder and systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a heterogeneous, multisystem autoimmune disorder characterized by unpredictable disease flares. Although the pathogenesis of SLE is complex, an epidemiologic link between posttraumatic stress disorder (PTSD) and the development of SLE has been identified, suggesting that stress-related disorders alter the susceptibility to SLE. Despite the strong epidemiologic evidence connecting PTSD and SLE, gaps remain in our understanding of how the two may be connected. Perturbations in the autonomic nervous system, neuroendocrine system, and at the genomic level may cause and sustain immune dysregulation that could lower the threshold for the development and propagation of SLE. We first describe shared risk factors for SLE and PTSD. We then describe potential biological pathways which may facilitate excessive inflammation in the context of PTSD. Among those genetically predisposed to SLE, systemic inflammation that accompanies chronic stress may fan the flames of smoldering SLE by priming immune pathways. Further studies on the connection between trauma and inflammation will provide important data on pathogenesis, risk factors, and novel treatments for SLE.

The Association Between Patterns of Trauma Exposure, Family Dysfunction, and Psychopathology Among Adolescent Females With Depressive Symptoms From Low-Income Contexts

Distinguishing profiles of trauma exposure among low-income adolescent females with depressive symptoms is important for understanding comorbidity, family relationships, and treatment. Specifically, child maltreatment is essential to examine in comparison to other traumas. Participants included 170 adolescent females (65.3% Black; 21.2% White; 13.5% other race; 14.1% Latina/x) with depressive symptoms and their primary caregiver from low-income families. Latent class analysis (LCA) identified three trauma classes. Probabilities of endorsing different subtypes of maltreatment (physical abuse, physical neglect, emotional abuse, emotional neglect, and sexual abuse), number of subtypes of maltreatment, and non-maltreatment traumas (accident, experiencing or witnessing physical assault, death or injury of loved one, medical trauma) varied among groups. Higher levels of family dysfunction and traumatic stress symptoms were reported in both classes with maltreatment exposure as compared to the class with only non-maltreatment trauma exposure. Findings have implications for family-focused interventions for maltreated adolescent females with depressive symptoms from low-income contexts.

Trauma-informed patient and public-engaged research: Development and evaluation of an online training programme

INTRODUCTION

As patients, members of the public, and professional stakeholders engage in co-producing health-related research, an important issue to consider is trauma. Trauma is very common and associated with a wide range of physical and behavioural health conditions. Thus, it may benefit research partnerships to consider its impact on their stakeholders as well as its relevance to the health condition under study. The aims of this article are to describe the development and evaluation of a training programme that applied principles of trauma-informed care (TIC) to patient- and public-engaged research.

METHODS

A research partnership focused on addressing trauma in primary care patients ('myPATH') explicitly incorporated TIC into its formation, governance document and collaborative processes, and developed and evaluated a free 3-credit continuing education online training. The training was presented by 11 partners (5 professionals, 6 patients) and included academic content and lived experiences.

RESULTS

Training participants (N = 46) positively rated achievement of learning objectives and speakers' performance (ranging from 4.39 to 4.74 on a 5-point scale). The most salient themes from open-ended comments were that training was informative (n = 12) and that lived experiences shared by patient partners were impactful (n = 10). Suggestions were primarily technical or logistical.

CONCLUSION

This preliminary evaluation indicates that it is possible to incorporate TIC principles into a research partnership's collaborative processes and training about these topics is well-received. Learning about trauma and TIC may benefit research partnerships that involve patients and public stakeholders studying a wide range of health conditions, potentially improving how stakeholders engage in co-producing research as well as producing research that addresses how trauma relates to their health condition under study.

PATIENT OR PUBLIC CONTRIBUTION

The myPATH Partnership includes 22 individuals with professional and lived experiences related to trauma (https://www.usf.edu/cbcs/mhlp/centers/mypath/); nine partners were engaged due to personal experiences with trauma; other partners are community-based providers and researchers. All partners contributed ideas that led to trauma-informed research strategies and training. Eleven partners (5 professionals, 6 patients) presented the training, and 12 partners (8 professionals, 4 patients) contributed to this article and chose to be named as authors.

Stressors and symptoms associated with a history of adverse childhood experiences among older adolescents and young adults during the COVID-19 pandemic in Manitoba, Canada

INTRODUCTION

The COVID-19 pandemic has had major economic, social and psychological consequences for adolescents and young adults. It is unclear whether those with a history of adverse childhood experiences (ACEs) were particularly vulnerable. We examined whether a history of ACEs was associated with financial difficulties, lack of emotional support, feeling stressed/anxious, feeling down/depressed, increased alcohol and/or cannabis use and increased conflict with parents, siblings and/or intimate partners among 16- to 21-year-olds during the pandemic.

METHODS

Data were collected in November and December 2020 from respondents aged 16 to 21 years (n = 664) participating in the longitudinal and intergenerational Well-being and Experiences Study (Wave 3) conducted in Manitoba, Canada. Age-stratified associations between ACEs and pandemic-related stressors/symptoms were examined with binary and multinomial logistic regression.

RESULTS

A history of ACEs was associated with pandemic-related financial difficulties (adjusted relative risk ratio [aRRR] range: 2.44-7.55); lack of emotional support (aRRR range: 2.13-26.77); higher levels of feeling stressed/anxious and down/depressed (adjusted odds ratio [aOR] range: 1.78-5.05); increased alcohol and cannabis use (aOR range: 1.99-8.02); and increased relationship conflict (aOR range: 1.98-22.59). Fewer associations emerged for older adolescents and these were not to the same degree as for young adults.

CONCLUSION

Adolescents and young adults with a history of ACEs reported increased odds of pandemic-related stressors and symptoms, and may need more resources and greater support compared to peers without an ACE history. Differences in results for adolescents and young adults suggest that interventions should be tailored to the needs of each age group.

Bibliometric analysis of post-traumatic stress disorder in forensic medicine: Research trends, hot spots, and prospects

Background

Post-traumatic stress disorder (PTSD) has various risk factors, complex pathogenesis, and diverse symptoms, and is often comorbid with other injuries and diseases, making forensic diagnosis difficult.

Methods

To explore the current research status and trends of PTSD, we used the Web of Science Core Collection databases to screen PTSD-related literature published between 2010 and 2021 and CiteSpace to perform bibliometric analysis.

Results

In recent years, PTSD-related research has grown steadily. The countries and institutions with the most research results were the United States and England, and King's College London and Boston University, respectively. Publications were identified from 2,821 different journals, including 13 forensic-related journals, but the journal distribution was relatively scattered and there was a lack of professional core journals. Keyword co-occurrence and clustering identified many hot topics; "rat model," "mental health," and "satisfaction" were the topics most likely to have a clear effect on future research. Analysis extracted nine turning points from the literature that suggested that neural network centers, the hypothalamic-pituitary-adrenal axis, and biomarkers were new research directions. It was found that COVID-19 can cause severe psychological stress and induce PTSD, but the relationship needs further study. The literature on stress response areas and biomarkers has gradually increased over time, but specific systemic neural brain circuits and biomarkers remain to be determined.

Conclusion

There is a need to expand the collection of different types of biological tissue samples from patients with different backgrounds, screen PTSD biomarkers and molecular targets using multi-omics and molecular biology techniques, and establish PTSD-related molecular networks. This may promote a systematic understanding of the abnormal activation of neural circuits in patients with PTSD and help to establish a personalized, accurate, and objective forensic diagnostic standard.

Childhood adversities and risk of posttraumatic stress disorder and major depression following a motor vehicle collision in adulthood

AIMS

Childhood adversities (CAs) predict heightened risks of posttraumatic stress disorder (PTSD) and major depressive episode (MDE) among people exposed to adult traumatic events. Identifying which CAs put individuals at greatest risk for these adverse posttraumatic neuropsychiatric sequelae (APNS) is important for targeting prevention interventions.

METHODS

Data came from n = 999 patients ages 18-75 presenting to 29 U.S. emergency departments after a motor vehicle collision (MVC) and followed for 3 months, the amount of time traditionally used to define chronic PTSD, in the Advancing Understanding of Recovery After Trauma (AURORA) study. Six CA types were self-reported at baseline: physical abuse, sexual abuse, emotional abuse, physical neglect, emotional neglect and bullying. Both dichotomous measures of ever experiencing each CA type and numeric measures of exposure frequency were included in the analysis. Risk ratios (RRs) of these CA measures as well as complex interactions among these measures were examined as predictors of APNS 3 months post-MVC. APNS was defined as meeting self-reported criteria for either PTSD based on the PTSD Checklist for DSM-5 and/or MDE based on the PROMIS Depression Short-Form 8b. We controlled for pre-MVC lifetime histories of PTSD and MDE. We also examined mediating effects through peritraumatic symptoms assessed in the emergency department and PTSD and MDE assessed in 2-week and 8-week follow-up surveys. Analyses were carried out with robust Poisson regression models.

RESULTS

Most participants (90.9%) reported at least rarely having experienced some CA. Ever experiencing each CA other than emotional neglect was univariably associated with 3-month APNS (RRs = 1.31-1.60). Each CA frequency was also univariably associated with 3-month APNS (RRs = 1.65-2.45). In multivariable models, joint associations of CAs with 3-month APNS were additive, with frequency of emotional abuse (RR = 2.03; 95% CI = 1.43-2.87) and bullying (RR = 1.44; 95% CI = 0.99-2.10) being the strongest predictors. Control variable analyses found that these associations were largely explained by pre-MVC histories of PTSD and MDE.

CONCLUSIONS

Although individuals who experience frequent emotional abuse and bullying in childhood have a heightened risk of experiencing APNS after an adult MVC, these associations are largely mediated by prior histories of PTSD and MDE.

Fatty acid amide hydrolase C385A polymorphism affects susceptibility to various diseases

The endocannabinoid (eCB) system is an important neuromodulatory system with its extensive network of receptors throughout the human body that has complex actions in the nervous system, immune system, and all of the body's other organs. Fatty acid amide hydrolase (FAAH) is an important membrane-bound homodimeric degrading enzyme that controls the biological activity of N-arachidonoylethanolamide (AEA) in the eCB system and other relevant bioactive lipids. It has been shown that several single nucleotide polymorphisms (SNPs) of FAAH are associated with various phenotypes and diseases including cardiovascular, endocrine, drug abuse, and neuropsychiatric disorders. A common functional and most studied polymorphism of this gene is C385A (rs324420), which results in the replacement of a conserved proline to threonine in the FAAH enzyme structure, leads to a reduction of the activity and expression of FAAH, compromises the inactivation of AEA and causes higher synaptic concentrations of AEA that can be associated with several various phenotypes. The focus of this review is on evidence-based studies on the associations of the FAAH C385A polymorphism and the various diseases or traits. Although there was variability in the results of these reports, the overall consensus is that the FAAH C385A genotype can affect susceptibility to some multifactorial disorders and can be considered a potential therapeutic target.

A phenomenological exploration of work-related post-traumatic growth among high-functioning adults maltreated as children

Introduction

Childhood maltreatment is a highly prevalent traumatic experience, and its adverse psychological and behavioral consequences are well-documented. Notwithstanding these adverse outcomes, many individuals who suffered from traumatic experiences report post-traumatic growth, i.e., transformative positive changes resulting from their struggle to cope. Post-traumatic growth has been extensively explored among adult survivors of childhood maltreatment, with findings indicating both the previously recognized domains (personal strength, relating to others, appreciation of life, openness to new possibilities, and spiritual change) as well as abuse-specific domains of growth (e.g., increased ability to protect themselves from abuse). However, little attention has been given to vocational aspects of post-traumatic growth among survivors, despite the central role and importance of work in adulthood. Exploration of post-traumatic growth at work has focused on certain vocational traumatic experiences, such as those which occur in the military, or through secondary trauma. This exploratory qualitative study focuses on the question: What is the lived experience of work-related post-traumatic growth among high-functioning adult survivors of CM?

Method

Twenty in-depth interviews were held with high-functioning working adults who were maltreated as children. Phenomenological analysis was applied to the retrospective data reported in these interviews.

Result

Rich descriptions of work-related positive psychological changes were provided by all participants. Analysis revealed that survivors' post-traumatic growth corresponded with all five previously recognized domains of growth: changes in self, relating to others, openness to new possibilities, finding meaning to the abuse, and appreciation of life. It also revealed that work is perceived as a form of resistance (a subtheme of changes in self), and that finding meaning entails three emerging subthemes: being a survivor and a role model, giving others what was needed and never received, and making a better world.

Discussion

While the vocational lives of survivors of childhood maltreatment have rarely been examined through the lens of post-traumatic growth, our results show this lens to be highly valuable. Work-related post-traumatic growth has relevance not only regarding vocational traumas occurring in adulthood as has been previously studied, but also in the context of childhood traumas. Moreover, our research broadens the understanding of the possible domains of work-related growth.

PTSD and depressive symptoms in Chinese adolescents exposed to multiple stressors from natural disasters, stressful life events, and maltreatment: A dose-response effect

Objectives

Little is known about the effects and the extent that childhood adversity has on post-traumatic stress disorder (PTSD) and depression.

Study design

A population-based, epidemiological study from the Wenchuan earthquake.

Methods

A total of 5,195 Wenchuan Earthquake adolescent survivors aged 11-18 years from nine high schools in southwest China completed questionnaires that assessed their PTSD and depression symptoms due to childhood maltreatment, stressful life events, and childhood earthquake exposure.

Results

The PTSD and depression prevalences were 7.1 and 32.4%. After controlling for age and gender, the multiple linear regressions revealed that stressful life events had the most significant direct effect on depression (β = 0.491), followed by childhood emotional abuse (β = 0.085), and earthquake exposure (β = 0.077). Similarly, stressful life events (β = 0.583) were found to have more significant direct effects on PSTD, followed by earthquake exposure (β = 0.140); however, childhood emotional abuse was not found to have an effect. The structural equation modeling (SEM) revealed that there were interactions between the three childhood adversities, with all three concurrently affecting both PTSD and depression.

Conclusion

These findings add weight to the supposition that psychological maltreatment, negative life events, and earthquake exposure contribute to PTSD and depression. In particular, the identification of subgroups that have a high prevalence of these childhood adversities could assist professionals to target populations that are at high risk of mental health problems.

The role of hippocampal CaMKII in resilience to trauma-related psychopathology

Traumatic stress exposure can form persistent trauma-related memories. However, only a minority of individuals develop post-traumatic stress disorder (PTSD) symptoms upon exposure. We employed a rat model of PTSD, which enables differentiating between exposed-affected and exposed-unaffected individuals. Two weeks after the end of exposure, male rats were tested behaviorally, following an exposure to a trauma reminder, identifying them as trauma 'affected' or 'unaffected.' In light of the established role of hippocampal synaptic plasticity in stress and the essential role of Ca2+/calmodulin-dependent protein kinase II (CaMKII) in hippocampal based synaptic plasticity, we pharmacologically inhibited CaMKII or knocked-down (kd) αCaMKII (in two separate experiments) in the dorsal dentate gyrus of the hippocampus (dDG) following exposure to the same trauma paradigm. Both manipulations brought down the prevalence of 'affected' individuals in the trauma-exposed population. A day after the last behavioral test, long-term potentiation (LTP) was examined in the dDG as a measure of synaptic plasticity. Trauma exposure reduced the ability to induce LTP, whereas, contrary to expectation, αCaMKII-kd reversed this effect. Further examination revealed that reducing αCaMKII expression enables the formation of αCaMKII-independent LTP, which may enable increased resilience in the face of a traumatic experience. The current findings further emphasize the pivotal role dDG has in stress resilience.

Intimate partner violence perpetration and sexual risk behaviour: Identifying shared determinants among young men in Tanzania

In this study we examined factors that predict involvement in different patterns of sexual risk behavior and IPV perpetration among young men in Tanzania (n = 979), with a focus on identifying factors that distinguish men who engage in both behaviours from those who do not. Risk factors were drawn from three domains thought to be upstream drivers of both IPV and sexual risk: poverty, adverse childhood experiences, and inequitable gender norms. A three-step latent class analysis was used to assess whether and how factors from each domain distinguished subgroups of men whose behaviour patterns were characterised as comorbid (involvement in IPV and sexual risk behaviour), IPV-only, sexual risk only, and normative (low risk). Consistent with expectations, greater food insecurity, adverse childhood experiences, and inequitable gender norms related to violence and sexual behaviour predicted increased risk of membership in the comorbid group compared to other sub-groups. Findings support the promise of integrated prevention programmes targeting the common causes of IPV perpetration and sexual risk behaviour.

The mediating role of post-traumatic stress disorder symptoms in the relationship between childhood adversities and depressive symptoms in two samples

BACKGROUND

Childhood adversities have been increasingly recognized as a significant risk factor for depression. However, the underlying mediating mechanism between childhood adversities and depression requires further investigation. The literature shows that childhood adversities are also closely associated with post-traumatic stress disorder (PTSD) symptoms and that PTSD symptoms can predict depressive symptoms. It remains unexplored whether PTSD symptoms can act as a mediator between childhood adversities and depression.

OBJECTIVES

The primary goal of this study was to examine whether PTSD symptoms would mediate the relationship between childhood adversities and depressive symptoms.

PARTICIPANTS AND SETTING

We examined in a convenience sample of Hong Kong adults aged 18 or above (N = 418) whether PTSD symptoms would mediate the relationship between childhood adversities and depressive symptoms. We then examined and compared the results with those in another convenience sample of Chinese-speaking young adults (mainly from Taiwan and Hong Kong) aged between 18 and 24 (N = 205). Participants in both samples completed online surveys that included measures of childhood adversities, PTSD symptoms and depressive symptoms.

RESULTS

Childhood adversities were significantly associated with depressive symptoms; and this relationship was mediated by PTSD symptoms in both samples.

CONCLUSION

This study is one of very few studies demonstrating that PTSD symptoms mediate the relationship between childhood adversities and depressive symptoms. Our findings suggest that addressing unresolved PTSD symptoms for adults with childhood adversities may help in preventing or treating depressive symptoms. Therefore, PTSD symptoms should be taken into account in the prevention and management of depression.

Epigenetic Age Acceleration and Risk for Posttraumatic Stress Disorder following Exposure to Substantiated Child Maltreatment

OBJECTIVE

Child maltreatment is among the strongest predictors of posttraumatic stress disorder (PTSD). However, less than 40% of children who have been maltreated are ever diagnosed with PTSD, suggesting that exposure to child maltreatment alone is insufficient to explain this risk. This study examined whether epigenetic age acceleration, a stress-sensitive biomarker derived from DNA methylation, explains variation in PTSD diagnostic status subsequent to child maltreatment.

METHOD

Children and adolescents (N = 70; 65.7% female), 8-15 years of age (M = 12.00, SD = 2.37) and exposed to substantiated child maltreatment within the 12 months prior to study entry, were enrolled. Participants provided epithelial cheek cells via buccal swab for genotyping and quantification of epigenetic age acceleration within a case-control design. PTSD diagnostic status was determined using the Child PTSD Symptoms Scale according to the DSM-IV-TR algorithm.

RESULTS

Epigenetic age acceleration predicted current PTSD status, revealing an effect size magnitude in the moderate range, OR = 2.35, 95% CI: 1.22- 4.51, after adjusting for sample demographics, polygenic risk for PTSD, and lifetime exposure to other childhood adversities. Supplemental analyses demonstrated that epigenetic age acceleration was related to a greater severity of PTSD arousal symptoms (r =.29, p =.015). There were no differential effects for child maltreatment subtype on epigenetic age acceleration or PTSD status.

CONCLUSIONS

The biological embedding of child maltreatment may explain variation in PTSD diagnostic status and serve as a novel approach for informing selective prevention or precision-based therapeutics for those at risk for PTSD.

Examining Associations between Adverse Childhood Experiences and Posttraumatic Stress Disorder Symptoms among Young Survivors of Urban Violence

Our study examines the association between Adverse Childhood Experience (ACE) exposure and posttraumatic stress disorder (PTSD) symptoms among survivors of violence. In this cross-sectional study, an ACE questionnaire and PTSD Checklist for DSM-5 (PCL-5) were completed by 147 participants ≤ 3 months after presenting to a Philadelphia, PA emergency department between 2014 and 2019 with a violent injury. This study treated ACEs, both separate and cumulative, as exposures and PTSD symptom severity as the outcome. Most participants (63.3%) met criteria for provisional PTSD, 90% reported experiencing ≥ 1 ACE, and 39% reported experiencing ≥ 6 ACEs. Specific ACEs were associated with increasing PCL-5 scores and increased risk for provisional PTSD. Additionally, as participants' cumulative ACE scores increased, their PCL-5 scores worsened (b = 0.16; p < 0.05), and incremental ACE score increases predicted increased odds for a positive provisional PTSD screen. Results provide further evidence that ACEs exacerbate the development of PTSD in young survivors of violence. Future research should explore targeted interventions to treat PTSD among survivors of interpersonal violence.

Patterns of adversity and post-traumatic stress among children adopted from care

BACKGROUND

Children adopted from care are more likely to have experienced early adversity, but little is known about the impact of early adversity on later post-traumatic stress (PTS) symptoms.

OBJECTIVE

To investigate sub-groups of adversity in a sample of adopted children and examine the association with later PTS symptoms.

PARTICIPANTS AND SETTING

A study of British children adopted from care using social worker records (N = 374) and questionnaire-based longitudinal study of n = 58 children over 4-years post adoptive placement.

METHODS

We used latent class analysis to identify subgroups of children based on commonalities in perinatal and postnatal adversity experienced prior to adoption and examined differences in PTS symptoms at 4-years post-placement between subgroups.

RESULTS

Nearly one in five (19 %) children were in the clinical or borderline ranges for symptoms of PTS arousal, 14 % for PTS avoidance and 8 % for PTS intrusion. The 5-class solution fitted the data best, with one class characterized by children with a low probability of experiencing any adversity, one perinatal adversity class and three classes capturing different patterns of adversity. The multiple complex adversity class involving both perinatal and postnatal adversity had significantly higher symptoms of PTS avoidance and arousal than other sub-groups.

CONCLUSIONS

The prevalence and complexity of PTS symptoms among adoptive children highlights the need for effective interventions considering different profiles of early adversity.
