Trauma and PTSD in the WHO World Mental Health Surveys

Towards accurate screening and prevention for PTSD (2-ASAP): protocol of a longitudinal prospective cohort study

BACKGROUND

Effective preventive interventions for PTSD rely on early identification of individuals at risk for developing PTSD. To establish early post-trauma who are at risk, there is a need for accurate prognostic risk screening instruments for PTSD that can be widely implemented in recently trauma-exposed adults. Achieving such accuracy and generalizability requires external validation of machine learning classification models. The current 2-ASAP cohort study will perform external validation on both full and minimal feature sets of supervised machine learning classification models assessing individual risk to follow an adverse PTSD symptom trajectory over the course of 1 year. We will derive these models from the TraumaTIPS cohort, separately for men and women.

METHOD

The 2-ASAP longitudinal cohort will include N = 863 adults (N = 436 females, N = 427 males) who were recently exposed to acute civilian trauma. We will include civilian victims of accidents, crime and calamities at Victim Support Netherlands; and who were presented for medical evaluation of (suspected) traumatic injuries by emergency transportation to the emergency department. The baseline assessment within 2 months post-trauma will include self-report questionnaires on demographic, medical and traumatic event characteristics; potential risk and protective factors for PTSD; PTSD symptom severity and other adverse outcomes; and current best-practice PTSD screening instruments. Participants will be followed at 3, 6, 9, and 12 months post-trauma, assessing PTSD symptom severity and other adverse outcomes via self-report questionnaires.

DISCUSSION

The ultimate goal of our study is to improve accurate screening and prevention for PTSD in recently trauma-exposed civilians. To enable future large-scale implementation, we will use self-report data to inform the prognostic models; and we will derive a minimal feature set of the classification models. This can be transformed into a short online screening instrument that is user-friendly for recently trauma-exposed adults to fill in. The eventual short online screening instrument will classify early post-trauma which adults are at risk for developing PTSD. Those at risk can be targeted and may subsequently benefit from preventive interventions, aiming to reduce PTSD and relatedly improve psychological, functional and economic outcomes.

The Psychosocial Consequences of Sexual Violence Stigma: A Scoping Review

Over the past decade, scholars have explored whether the stigma associated with sexual violence (SV) represents a risk factor for psychopathology and related comorbidities following SV. We conducted a scoping review to summarize and evaluate the state of this burgeoning literature. We included studies from Pubmed, APA PsychInfo, Embase, CINAHL Plus, Social Science Premium, and Web of Science that quantified stigma related to SV. Studies were screened and abstracted in accordance with the PRISMA-SCR guidelines for scoping reviews. Our final sample contained 62 studies. We address two key questions about SV stigma. First, is SV a stigmatized status? Articles (n = 14) provided evidence for SV stigma among potential stigmatizers (e.g., individuals who may perpetuate stigma) across a range of methods (e.g., vignettes) and outcomes (e.g., desire for social distance). Additional work (n = 20) corroborates perceptions of SV stigma among targets (i.e., SV survivors). Second, what are the psychosocial consequences of SV stigma? We reviewed studies (n = 28) demonstrating that SV stigma is correlated with a range of adverse psychosocial outcomes-including anxiety, depression, posttraumatic stress disorder, problematic drinking, and somatic symptoms-among individuals experiencing multiple types of SV (e.g., childhood sexual abuse and sexual assault). Thus, emerging evidence suggests that SV stigma may be a critical determinant of risk and recovery following SV exposure. However, a number of limitations were observed, including that SV stigma has not been consistently measured and that the literature has not fully incorporated stigma constructs, such as concealment and structural stigma. We offer several recommendations to advance this line of work.

The Shield of Self-Esteem: Buffering against the Impact of Traumatic Experiences, Fear, Anxiety, and Depression

BACKGROUND

Adverse life occurrences (e.g., severe accidents, violence/abuse, organic disorders such as COVID-19) can elicit traumatic responses that heighten fear, anxiety, and depression. However, scientific research has shown that certain variables, such as self-esteem, based on theories like terror management theory (TMT) and the anxiety-buffering hypothesis (ABH), can mitigate the negative effects of trauma. This study aimed to test the ABH by assessing the buffering role of self-esteem in the relationships among the impact of traumatic experiences, fear, anxiety, and depression.

METHOD

An observational research design was used. This study involved 321 participants who experienced COVID-19 as a traumatic experience. A sequential multiple-mediation model with observed variables (path analysis) was used to test the impact of the traumatic experience on fear, anxiety, and depression, examining the protective role of self-esteem.

RESULTS

A path analysis revealed that fear and anxiety mediated the relationship between the impact of the traumatic experience of COVID-19 and depression. Additionally, in line with the ABH, self-esteem was found to mediate the relationship between the predictors and their adverse psychological consequences. This suggests that self-esteem played a buffering role, mitigating the negative impact of traumatic experiences on mental health outcomes.

CONCLUSIONS

These findings underscore the central mediating role of self-esteem, as well as fear and anxiety, in the pathway from trauma-related factors to depression. These insights advocate for evidence-based interventions aimed at alleviating the psychological suffering associated with traumatic experiences, fostering adaptation, and supporting psychological health.

Trauma Exposure Checklist: Preliminary Results Show Promising Psychometric Properties to Assess Subjective Perceptions of Exposure to Potentially Traumatic Events

Most individuals in the general population will be exposed to potentially traumatic situations at some point in their lifespan. There is a strong body of research focusing on the clinical implications of exposure to potentially traumatic situations, but less attention has been given to psychological adjustment following these events. Very few available instruments assess trauma exposure while considering subjective perceptions of both positive and negative features. In this study, 304 adults from the general population, mostly women of middle and high socioeconomic status (mean age = 43), filled in a questionnaire with sociodemographic questions and an adapted version of the Trauma Exposure Checklist, which was originally developed in the context of the COVID-19 pandemic. Results indicate that most participants have experienced a potentially traumatic event, most prevalently related to violence and/or criminality and to the severe illnesses and deaths of close relatives. Principal components and reliability analyses lent support to a three-factor structure that considers perceptions of internal and external losses and a positive factor that addresses resources and social support. This study is a first step towards advancing our knowledge on the impact of developmental and sociodemographic factors on subjective experiences of psychological crises and, consequently, psychological adjustment throughout the lifespan.

Profiles of Trauma Exposure Type and Its Associations With Pain-Related Outcomes Among Adults With Chronic Pain: A 2-Year Longitudinal Study

Individuals with chronic pain report disproportionally higher rates of trauma, yet it is unclear whether different types of trauma (eg, sexual, accidental trauma) are associated with worse pain outcomes. The present study sought to 1) identify subgroups of people with chronic pain based on trauma type, and 2) determine whether subgroups differ in terms of pain characteristics over a 2-year period. Individuals with chronic pain (N = 1,451) participated in an online study and completed self-report questionnaires at baseline, 3-, 12-, and 24-month follow-up. Trauma was assessed via the Life Events Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Pain intensity and interference were measured via the Brief Pain Inventory, and pain distribution was evaluated using the Widespread Pain Index. Latent class analyses produced a 3-class solution consisting of individuals with high and diverse trauma (16.3%), high sexual trauma (18.4%), and low/accidental trauma (57.1%) with the rest of the sample endorsing no trauma history (8.2%). After controlling for key demographic variables and baseline outcome levels, individuals in the high- and diverse trauma group endorsed higher levels of pain severity and interference at the 3- and 12-month follow-ups compared with the group with no trauma (P < .01). Additionally, relative to the no trauma group, individuals in the high sexual trauma group reported higher levels of pain interference and more widespread pain at the 3-month follow-up (P < .05). The findings underscore the importance of screening for trauma and suggest that the type and variety of trauma experienced may be relevant to pain-related outcomes. PERSPECTIVE: This article highlights how an individual's unique trauma history may be related to their current pain experience. Knowledge of the type and frequency of past trauma may have relevant clinical implications for the treatment of chronic pain.

The Effectiveness and Implementation of Psychological First Aid as a Therapeutic Intervention After Trauma: An Integrative Review

Psychological First Aid (PFA) is known to be an initial early intervention following traumatic exposure, yet little is known about its optimal implementation and effectiveness. This review aims to examine the evidence for the effectiveness of PFA interventions and how PFA interventions have been designed, implemented, and experienced. MEDLINE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, PsychINFO, Embase, Web of Science, PILOTS, and China National Knowledge Infrastructure (in Chinese) databases were searched. Twenty studies from 4,735 records were included and quality rated, followed by an integrative synthesis of quantitative and qualitative evidence. PFA intervention following trauma exposure shows a positive effect for reducing anxiety and facilitating adaptive functioning in the immediate and intermediate term, yet the evidence for reducing Post-traumatic stress disorder/depressive symptoms is less compelling. Furthermore, commonalities in the components and techniques across different PFA approaches identified tend to align with four of Hobfoll's five essential elements: safety, calm, efficacy, and connectedness (as reflected among 7/11 PFA protocols), whereas the "hope" element was less developed. These commonalities include active listening, relaxation/stabilization, problem-solving/practical assistance, and social connection/referral. Intensive techniques such as cognitive reconstruction have also been incorporated, intensifying PFA delivery. The substantial variation observed in PFA format, timing, and duration, coupled with inadequate documentation of fidelity of implementation and adaptation, further constrains the ability to inform best practices for PFA. This is concerning for lay frontline providers, vital in early trauma response, who report implementation challenges despite valuing PFA as a time-sensitive, supportive, and practical approach.

The Use of Dance and Movement for the Embodied Healing of Interpersonal Trauma in Women and Girls: A Systematic Review

Interpersonal trauma is a pervasive issue with devastating consequences for women and girls of diverse identities. Research has shown that there are many potential physiological consequences for experiencing trauma, and as such, treatment for trauma should incorporate the body. Dance/Movement Therapy (DMT) has been emerging in the current literature as one body-oriented treatment approach effective in helping women and girls heal from interpersonal trauma. This review uses textual narrative evidence synthesis to examine how practitioners are currently using DMT for this population, what treatment outcomes have been observed, and what the racial/ethnic identities and international contexts are for survivors who have benefited from DMT. Inclusion criteria for the present review included peer-reviewed studies published in English between the years 2000 to 2022, reporting data on the use of dance or movement to help women and/or adolescent girls aged 12 and older heal from interpersonal trauma. Studies were identified through electronic databases, and 16 total studies met criteria. This review found that the characteristics and structure of DMT vary greatly between different practitioners, the participants of DMT are very diverse, and there are many commonly observed outcomes such as increased physical ability, increased emotional capacity, mind-body integration, safety, aid with trauma processing, empowerment, social support, and fun. This review also gives recommendations for practitioners who wish to utilize dance and movement in treatment: offer group interventions; use the body to create metaphor, imagery, and symbolism; give survivors choices in how they participate; use music purposefully; and don't forget to cultivate joy.

Epidemiology of Post-traumatic Stress Disorder in Iranian Population From 2019 to 2024: A Systematic Review and Meta-analysis

BACKGROUND

Post-traumatic stress disorder (PTSD) is a disorder that arises from experiencing traumatic events such as traffic accidents, war, natural disorders, and job incidents. This study focused on determining the epidemiology of PTSD in the Iranian population from 2019 to 2024.

METHODS

In this systematic review and meta-analysis, we explored databases such as PubMed, Embase, Web of Knowledge, Scopus, and Magiran to achieve a maximum variety of screened articles. The quality of the included articles was evaluated using the STROBE checklist. For data analysis, due to the variation in reporting the PTSD prevalence across the reviewed articles, heterogeneity was assessed using the I2 index, and a random effect model was applied to account for this variation.

RESULTS

Out of 800 articles found in the initial review, only 15 articles were entered in the final analysis based on inclusion and exclusion criteria, with a total of 9868 participants. The overall PTSD prevalence in the Iranian population was 31.87% (95% confidence interval [CI]=17.87- 45.87, I2=95.29%, P<0.001). Additionally, PTSD prevalence in men (36.64%) was higher than in women (35.52%).

CONCLUSION

The prevalence of PTSD in young Iranian men is relatively high, and there was no statistically significant decrease in PTSD prevalence between 2019 and 2024.

The Basics of Trauma-Informed Care in the NICU

This article will define the basics of trauma, adverse childhood event scoring, and social determinants of health and how they relate to the perinatal and NICU populations. It will then apply that foundation to identify and define a trauma-informed care approach to provide improved care to the families supported in the NICU.

Health and wellbeing of survivors of sexual violence and abuse attending sexual assault referral centres in England: the MESARCH mixed-methods evaluation

Background

One million people in England and Wales experience sexual violence and abuse each year, with nearly half experiencing serious sexual offences; around 30,000 survivors access sexual assault referral centres.

Objectives

This research was commissioned by National Institute for Health and Care Research to evaluate access, interventions and care pathways for survivors, especially those provided through sexual assault referral centres.

Design, setting, participants

The sexual assault referral centres care pathway was investigated through six sub-studies. There were two Cochrane Reviews (4274 participants). Seventy-two providers and 5 survivors were interviewed at eight sites; the children and young people study involved 12 participants from two sexual assault referral centres. A cohort study involving three-wave data collection over 1 year (21 sites; 2602 service users screened, 337 recruited) used a multilevel modelling framework to explore risk factors for burden of post-traumatic stress disorder symptoms at baseline and change at 1 year. We analysed costs and outcomes and conducted a narrative analysis (41 survivors). We worked closely with survivors and prioritised the safety/welfare of participants and researchers.

Results

Cochrane Reviews identified large effects from psychosocial interventions for post-traumatic stress disorder and depression. Sexual assault referral centres delivered a high-quality frontline service for survivors but groups experiencing domestic abuse and some ethnic and cultural minorities were under-represented. The qualitative research emphasised inter-agency collaboration for survivor benefit. The cohort study identified a risk 'triad' of adverse childhood experiences, poor mental health and economic deprivation, which was associated with baseline trauma burden. There were important improvements in trauma symptoms a year later. These improvements were unrelated to different sexual assault referral centre models. Costs and other outcomes were also similar across models. Harmful policing and justice practices/procedures were identified by 25% of participants. In this context, trauma-competent interviewing techniques, regular/timely updates and conveying case decisions with care signalled good practice.

Limitations

The cohort study lacked a comparison group, reducing confidence in the finding that access to sexual assault referral centres explained the reduction observed in post-traumatic stress disorder.

Conclusions and future work

Barriers to access call for concerted efforts to implement trauma-informed universal health services. The risk 'triad' underscores the value of holistic approaches to care at sexual assault referral centres and timely follow-on care. Poor mental health was the main barrier to service access beyond sexual assault referral centres. The persistence of trauma symptoms a year after accessing sexual assault referral centres signals urgent need for tackling counselling wait-lists, expanding support options and commitment to lifelong care. Multidisciplinary evaluation of sexual assault referral centres for better health provides a foundation for advancing trauma-informed practices in the context of sexual violence and abuse.

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.

Adult refugees' perspectives on the impact of trauma and post-migration hardships on learning

Background: Research shows that adult refugees' well-being and future in the reception country heavily depend on successfully learning the host language. However, we know little about how adult learners from refugee backgrounds experience the impact of trauma and adversity on their learning.Objective: The current study aims to investigate the perspectives of adult refugee learners on whether and how trauma and other adversity affect their learning.Methods: We conducted in-depth interviews with 22 adult refugees (10 women) attending the Norwegian Introduction Programme (NIP). The participants came from six Middle Eastern, Central Asian, and African countries. Two questionnaires were included, one about past stressful life events (SLESQ-Revised), and one about mental health symptoms and current psychological distress following potentially traumatic experiences (PCL-5).Results: Participants held varying beliefs about trauma's impact on learning: that it had a constant impact, that it was situational, or that it had no impact. Other aspects they brought up as having an essential effect on learning and school attendance include psychological burdens from past and present school experiences, and post-migration hardships such as loneliness, depression, ongoing violence, and negative social control. Post-migration trauma and hardships exacerbated the burden of previous trauma and were frequently associated with a greater negative influence on learning.Conclusion: This study adds new insights from adult refugee learners themselves into how post-migration hardships as well as trauma can impact their learning, and the importance of recognising their struggles. A safe space is required for refugees to open up about their difficulties in life and with learning. This knowledge can be used to enhance teaching practices, foster better teacher-student relationships, and inform policy-making decisions, ultimately benefiting both individuals and society.

Tentative Causes of Brain and Neuropsychological Alterations in Women Victims of Intimate Partner Violence

Victims of Intimate Partner Violence Against Women (IPVAW) experience neuropsychological and cerebral changes, which have been linked to several tentative causal mechanisms, including elevated cortisol levels, psychopathological disorders, traumatic brain injury (TBI), hypoxic/ischemic brain damage, and medical conditions related to IPVAW. While these mechanisms and their effects on brain function and neuropsychological health are well-documented in other clinical populations, they manifest with unique characteristics in women affected by IPVAW. Specifically, IPVAW is chronic and repeated in nature, and mechanisms are often cumulative and may interact with other comorbid conditions. Thus, in light of existing literature on neuropsychological alterations in other populations, and recognizing the distinct features in women who experience IPVAW, we propose a new theoretical model-the Neuro-IPVAW model. This framework aims to explain the complex interplay between these mechanisms and their impact on cognitive and brain health in IPVAW victims. We anticipate that this theoretical model will be valuable for enhancing our understanding of neuropsychological and brain changes related to intimate partner violence, identifying research gaps in these mechanisms, and guiding future research directions in this area.

Blood-based DNA methylation and exposure risk scores predict PTSD with high accuracy in military and civilian cohorts

BACKGROUND

Incorporating genomic data into risk prediction has become an increasingly popular approach for rapid identification of individuals most at risk for complex disorders such as PTSD. Our goal was to develop and validate Methylation Risk Scores (MRS) using machine learning to distinguish individuals who have PTSD from those who do not.

METHODS

Elastic Net was used to develop three risk score models using a discovery dataset (n = 1226; 314 cases, 912 controls) comprised of 5 diverse cohorts with available blood-derived DNA methylation (DNAm) measured on the Illumina Epic BeadChip. The first risk score, exposure and methylation risk score (eMRS) used cumulative and childhood trauma exposure and DNAm variables; the second, methylation-only risk score (MoRS) was based solely on DNAm data; the third, methylation-only risk scores with adjusted exposure variables (MoRSAE) utilized DNAm data adjusted for the two exposure variables. The potential of these risk scores to predict future PTSD based on pre-deployment data was also assessed. External validation of risk scores was conducted in four independent cohorts.

RESULTS

The eMRS model showed the highest accuracy (92%), precision (91%), recall (87%), and f1-score (89%) in classifying PTSD using 3730 features. While still highly accurate, the MoRS (accuracy = 89%) using 3728 features and MoRSAE (accuracy = 84%) using 4150 features showed a decline in classification power. eMRS significantly predicted PTSD in one of the four independent cohorts, the BEAR cohort (beta = 0.6839, p=0.006), but not in the remaining three cohorts. Pre-deployment risk scores from all models (eMRS, beta = 1.92; MoRS, beta = 1.99 and MoRSAE, beta = 1.77) displayed a significant (p < 0.001) predictive power for post-deployment PTSD.

CONCLUSION

The inclusion of exposure variables adds to the predictive power of MRS. Classification-based MRS may be useful in predicting risk of future PTSD in populations with anticipated trauma exposure. As more data become available, including additional molecular, environmental, and psychosocial factors in these scores may enhance their accuracy in predicting PTSD and, relatedly, improve their performance in independent cohorts.

Posttraumatic stress disorder (PTSD) prevalence: an umbrella review

Posttraumatic stress disorder (PTSD) is one of the most serious and incapacitating mental diseases that can result from trauma exposure. The exact prevalence of this disorder is not known as the literature provides very different results, ranging from 2.5% to 74%. The aim of this umbrella review is to provide an estimation of PTSD prevalence and to clarify whether the prevalence depends on the assessment methods applied (structured interview v. self-report questionnaire) and on the nature of the traumatic event (interpersonal v. not-interpersonal). A systematic search of major databases and additional sources (Google Scholar, EBSCO, Web of Science, PubMed, Galileo Discovery) was conducted. Fifty-nine reviews met the criteria of this umbrella review. Overall PTSD prevalence was 23.95% (95% confidence interval 95% CI 20.74-27.15), with no publication bias or significant small-study effects, but a high level of heterogeneity between meta-analyses. Sensitivities analyses revealed that these results do not change after removing meta-analysis also including data from underage participants (23.03%, 95% CI 18.58-27.48), nor after excluding meta-analysis of low quality (24.26%, 95% CI 20.46-28.06). Regarding the impact of diagnostic instruments on PTSD prevalence, the results revealed a lack of significant differences in PTSD prevalence when structured v. self-report instruments were applied (p = 0.0835). Finally, PTSD prevalence did not differ following event of intentional (25.42%, 95% CI 19.76-31.09) or not intentional (22.48%, 95% CI 17.22-27.73) nature (p = 0.4598). The present umbrella review establishes a robust foundation for future research and provides valuable insights on PTSD prevalence.

Long-term PTSD prevalence and associated adverse psychological, functional, and economic outcomes: a 12-15 year follow-up of adults with suspected serious injury

Background: An increasing number of longitudinal studies investigates long-term PTSD, related outcomes and potential gender differences herein. However, a knowledge gap exists when it comes to studies following individual civilian trauma beyond a decade post-trauma.Objective: To investigate the long-term PTSD prevalence, associated adverse psychological, functional and economic outcomes related to (suspected) serious injury of 12-15 years ago in Dutch adults, as well as potential gender differences herein.Method: N = 194 trauma-exposed adults (34% women) admitted to an emergency department following suspected serious injury completed a follow-up assessment 12-15 years (M = 14.30, SD = 1.00) post-trauma. Participants completed assessments of clinician-rated PTSD symptom severity, as well as self-report questionnaires on psychological, functional and economic outcomes.Results: Nine participants (4.8%) fulfilled the DSM-5 diagnostic criteria for PTSD related to the index trauma of 12-15 years ago. Results showed that PTSD symptom severity (CAPS-5) was significantly associated with more severe symptoms of anxiety (HADS) and depression (QIDS), lower well-being (WHO-5) and (health-related) quality of life (WHOQOL; EQ-5D-5L), but not with alcohol use (AUDIT), productivity loss at work (iPCQ) and health care use (iMCQ). No significant gender differences in the long-term PTSD prevalence nor in its related psychological, functional and economic outcomes were found.Conclusions: Our findings underscore the long-term presence of PTSD and associated adverse psychological and functional outcomes in a proportion of adults who experienced (suspected) serious injury over a decade ago. PTSD is already widely recognized for its substantial impact in the aftermath of a trauma. The current study emphasizes the potential long-term consequences of individual civilian trauma, highlighting the importance of accurate screening and prevention for PTSD.

Bereaved parents' and siblings' healthcare needs, healthcare utilization, and satisfaction with healthcare services eight years after the 2011 Utøya terror attack

Understanding the healthcare needs of bereaved individuals following terrorism is crucial for organizing healthcare services. This cross-sectional study examined the terror-related healthcare needs, healthcare utilization, and satisfaction with professional healthcare among 122 traumatically bereaved parents and siblings eight years after the 2011 Utøya terrorist attack in Norway. Results showed that over 50% of the participants currently needed help coping with their grief or with mental and somatic symptoms, and only 34% were actively utilizing healthcare related to the terror attack. Furthermore, 68% reported not getting sufficient help, suggesting a treatment gap. One-third rated the professional help and treatment as unsatisfactory, with 28% reporting that they had not received competent help. More somatic and posttraumatic stress symptoms were associated with higher healthcare needs, whilst higher levels of insomnia symptoms were associated with lower healthcare satisfaction. This emphasizes the need to recognize, professionally intervene, and provide competent support for traumatically bereaved individuals.

Advancing a new model of collaborative practice: a decade of Whole Health interprofessional education across Veterans Health Administration

Large-scale implementation of interprofessional education across the United States Veterans Health Administration has supported advancement of a new model of collaborative practice, the Whole Health System, centering on the patient and what matters most to them. Other health care systems can consider similar educational efforts for health care transformation.

Providing trauma-informed care in the acute care setting

Events such as the COVID-19 pandemic and the war in Ukraine have increased people's awareness of mental health issues. Psychological trauma impacts patients in the acute care setting through physical and mental health presentations. Trauma is a public health issue crossing all socioeconomic groups and is related to social determinants of health. Trauma-informed care (TIC) is an evidence-based approach to providing care. TIC is within the scope of nursing practice and improves outcomes for patients. However, there is a lack of standard terms or practices within healthcare. Additionally, there is superficial acknowledgment of the need for TIC at the local or national level regarding policy. Nurses need to adopt TIC into practice and advocate for policy change to improve the health and lives of those seeking care.

The psychometric properties of the Swahili version of the Primary Care Post Traumatic Stress Disorder screen for DSM-5 among adults in Kenya

Background

The psychometric properties of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) are undocumented in Kenya and sub-Saharan Africa (SSA) at large. This study aimed to evaluate the psychometric properties of the Swahili version of the tool, S-PC-PTSD-5, in a community sample of adults 18 years and older drawn from Nairobi, Mombasa and Kwale counties in Kenya.

Methods

Analysis of cross-sectional data from 1431 adults from the community was conducted, examining the reliability, factorial structure, measurement invariance, and convergent and divergent validity of the interviewer-administered S-PC-PTSD-5.

Results

Out of 1431 adults who completed the S-PC-PTSD-5, 666 (46.5%) reported experiencing at least one traumatic event. Internal consistency of the S-PC-PTSD-5 was good overall, with alpha and omega values above 0.7. Confirmatory factor analysis (CFA) results indicated a one-factor structure of the S-PC-PTSD-5 for the overall sample. Multigroup CFA also demonstrated factorial invariance for sex for the one-factor structure of S-PC-PTSD-5. Scores for S-PC-PTSD-5 significantly correlated (positively) with those of generalized anxiety disorder (GAD7) and depressive symptoms (PHQ9), indicating convergent validity. S-PC-PTSD-5 scores also significantly correlated (negatively) with the WHO-5 wellbeing index, supporting divergent validity.

Conclusions

The S-PC-PTSD-5 is a reliable and valid unidimensional measure. It appears to be a valuable screening measure for probable PTSD in both urban and rural community settings in Kenya. Nonetheless, to confidently identify those who may need treatment/additional support, further research on the reliability and validity of S-PC-PTSD-5 is required, especially its diagnostic accuracy at different cutoff scores.

Early Intervention after Rape to prevent post-traumatic stress symptoms (the EIR-study): an internal pilot study of a randomized controlled trial

BACKGROUND

Rape is one of the trauma incidents with the highest risk of subsequent post-traumatic stress disorder. Early interventions, such as prolonged exposure therapy (PE), have shown promise in preventing PTSD following a sexual assault. The primary objective of this internal pilot trial was to examine the feasibility of the EIR study protocol, which used modified prolonged exposure therapy (mPE) as a preventive intervention after rape.

METHODS

This parallel two-arm clinical pilot study involved three sexual assault centers (SACs) in Trondheim, Oslo, and Vestfold, with data collected between June 2022 and March 2023. Women seeking assistance at one of these three SACs within 72 h after rape or attempted rape received acute medical treatment and forensic examinations. Women who wanted further psychosocial treatment were, if eligible and consenting, recruited to complete baseline assessments and a clinical interview before being randomized to one of two study arms. The intervention group prescribed up to five sessions of modified PE (mPE) in addition to treatment as usual (TAU), starting within the first 14 days after the rape incident, followed by weekly sessions. The other group received TAU. The present pilot evaluation is based on 22 participants, i.e., nine mPE + TAU and 13 TAU alone. Primary outcomes were predefined progression criteria regarding recruitment, retention, intervention implementation, a harm reporting system, and applying biological measurements and actigraphy.

RESULTS

During the 6-month recruitment period, 235 women visited the three SACs. After eligibility screening and consent, 22 (9.4%) women were randomized. Three months later, 14 (63.6%) participants completed the final assessments. Intervention implementation was successful using trained SAC personnel to deliver mPE. The harm reporting system was used according to the study's plan, and adverse and serious adverse events were detected during the trial. The biological measurements and actigraphy had substantial missing data but were still considered usable for statistical analyses.

CONCLUSION

It may be feasible to conduct a full-scale RCT of early intervention after rape by comparing mPE + TAU to TAU alone. Minor design refinements were made to the protocol to enhance the main study outcome.

From loss to disorder: The influence of maladaptive coping on prolonged grief

Research indicates that post-bereavement coping strategies can be adaptive or maladaptive. Understanding which strategies lead to poorer outcomes is an important clinical and theoretical question with the potential to guide intervention. The Oxford Grief - Coping Strategies scale was developed from interviews with bereaved people with and without prolonged grief disorder (PGD) to assess the frequency of maladaptive cognitive and behavioural strategies after bereavement. Factorial and psychometric validity were assessed using exploratory and confirmatory factor analysis (N = 676). A three-wave cross-lagged panel model (N = 275) was used to assess the predictive validity of the tool in explaining symptoms of PGD. Results supported a four-factor solution (Avoidance, Proximity Seeking, Loss Rumination, Injustice Rumination) with good psychometric properties. The OG-CS predicted prospective symptoms of PGD in the short-term (6-12 months) and long term (12-18 months), controlling for baseline symptoms and autocorrelations. Subscale analyses demonstrated that the use of coping strategies predicted ICD-11 PGD in both the short-term and the long-term. However, avoidance was not predictive of outcomes early in the grieving process. At 6-12 months, avoidance predicted PGD at 12-18 months.

The role of prior trauma exposure and subsequent posttraumatic stress disorder in reactions to the COVID-19 pandemic: A qualitative study

OBJECTIVE

A growing body of literature suggests that the COVID-19 pandemic is a traumatic stressor capable of causing posttraumatic stress symptoms. People with a history of trauma, particularly those with posttraumatic stress disorder (PTSD), may be particularly vulnerable to the negative mental health impacts of the pandemic. However, qualitative research exploring potential differences in the lived experiences of and reactions to COVID-19 between people with and without PTSD is lacking.

METHOD

Semistructured interviews were conducted with 31 women (n = 15 women with probable PTSD, n = 16 women without probable PTSD) recruited from an ongoing U.S.-based cohort study. Themes were identified using inductive thematic analysis.

RESULTS

The majority of women with PTSD described their level of fear or perceived safety related to COVID-19 as a major factor influencing their mental health during the pandemic. In contrast, women without PTSD indicated that their level of distress was largely driven by pandemic-related restrictions on normal activities and family events. Many women with PTSD also described feeling anger or frustration toward people they perceived as not taking the COVID-19 pandemic seriously. Only one participant without PTSD expressed similar feelings.

CONCLUSIONS

This study found notable differences in reactions to the COVID-19 pandemic between people with and without PTSD, with findings that are likely relevant to future disasters. These findings can inform the development of preparedness policies for future disasters, pandemics, or other collective traumas to prevent distress and improve mental health, particularly for vulnerable populations such as individuals with preexisting PTSD.

The Impact of Childhood Trauma on the Negative Symptoms of Schizophrenia

ABSTRACT

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

Three distinct patterns of mental health response following accidents in mountain sports: a follow-up study of individuals treated at a tertiary trauma center

The restorative effect of physical activity in alpine environments on mental and physical health is well recognized. However, a risk of accidents and post-accident mental health problems is inherent to every sport. We aimed to characterize mental health in individuals following mountain sport accidents requiring professional medical management. Adult victims of mountain sport accidents treated at the hospital of the Medical University of Innsbruck (Austria) between 2018 and 2020 completed a cross-sectional survey at least 6 months following the admission (median 44 months, n = 307). Symptoms of post-traumatic stress disorder (PTSD, PCL-5), anxiety, depression, and somatization (PHQ), resilience (RS-13), sense of coherence (SOC-9L), post-traumatic growth (PTGI), and quality of life (EUROHIS-QOL), as well as sociodemographic and clinical information, were obtained from an online survey and extracted from electronic health records. Mental health outcome patterns were investigated by semi-supervised medoid clustering and modeled by machine learning. Symptoms of PTSD were observed in 19% of participants. Three comparably sized subsets of participants were identified: a (1) neutral, (2) post-traumatic growth, and (3) post-traumatic stress cluster. The post-traumatic stress cluster was characterized by high prevalence of symptoms of mental disorders, low resilience, low sense of coherence, and low quality of life as well as by younger age, the highest frequency of pre-existing mental disorders, and persisting physical health consequences of the accident. Individuals in this cluster self-reported a need for psychological or psychiatric support following the accident and more cautious behavior during mountain sports since the accident. Reliability of machine learning-based prediction of the cluster assignment based on 40 variables available during acute medical treatment of accident victims was limited. A subset of individuals show symptoms of mental health disorders including symptoms of PTSD when assessed at least 6 months after mountain sport accident. Since early identification of these vulnerable patients remains challenging, psychoeducational measures for all patients and low-threshold access to mental health support are key for a successful interdisciplinary management of victims of mountain sport accidents.

Advancing trauma studies: A narrative literature review embracing a holistic perspective and critiquing traditional models

Background

Trauma is commonly understood as a psychological and emotional response to distressing events. The subjective nature of trauma experiences has led to ongoing debates about the best theoretical frameworks for understanding and addressing trauma. This review aims to comprehensively critique traditional biomedical and psychological models and advocates for more inclusive and culturally sensitive frameworks.

Methods

A narrative literature review was conducted, synthesizing data from 96 peer-reviewed journal articles, books, and authoritative reports from databases such as PubMed, PsycINFO, and Google Scholar. The review focused on studies related to trauma, post-traumatic stress disorder (PTSD), complex trauma, and related disorders, emphasizing both individual and socio-cultural aspects.

Results

The review identifies several key criticisms of trauma models. For biological models, critiques include the oversimplification of trauma experiences, insufficient developmental considerations, failure to capture diverse trauma responses, limited cultural sensitivity, and inadequacy of the categorical approach. For psychological models, criticisms encompass an overemphasis on internal processes, neglect of developmental impacts, limited focus on symptom diversity, challenges in addressing socio-cultural contexts, and incomplete integration of emotional and relational aspects. These findings underscore the need for more comprehensive, culturally sensitive, and developmentally informed trauma frameworks.

Conclusion

The findings emphasize the importance of adopting a holistic perspective in trauma research and treatment. By integrating individual, interpersonal, and socio-cultural dimensions, future research and interventions can better support trauma survivors. This approach necessitates ongoing interdisciplinary collaboration and the inclusion of diverse voices, including those of trauma survivors, to refine current methodologies and enhance therapeutic outcomes.

On the basis of sex and sleep: the influence of the estrous cycle and sex on sleep-wake behavior

The recurrent hormonal fluctuations within reproductive cycles impact sleep-wake behavior in women and in rats and mice used in preclinical models of sleep research. Strides have been made in sleep-related clinical trials to include equal numbers of women; however, the inclusion of female rodents in neuroscience and sleep research is lacking. Female animals are commonly omitted from studies over concerns of the effect of estrus cycle hormones on measured outcomes. This review highlights the estrous cycle's broad effects on sleep-wake behavior: from changes in sleep macroarchitecture to regionally specific alterations in neural oscillations. These changes are largely driven by cycle-dependent ovarian hormonal fluctuations occurring during proestrus and estrus that modulate neural circuits regulating sleep-wake behavior. Removal of estrous cycle influence by ovariectomy ablates characteristic sleep changes. Further, sex differences in sleep are present between gonadally intact females and males. Removal of reproductive hormones via gonadectomy in both sexes mitigates some, but not all sex differences. We examine the extent to which reproductive hormones and sex chromosomes contribute to sex differences in sleep-wake behavior. Finally, this review addresses the limitations in our understanding of the estrous cycle's impact on sleep-wake behavior, gaps in female sleep research that are well studied in males, and the implications that ignoring the estrous cycle has on studies of sleep-related processes.

Posttraumatic stress disorder (PTSD) and complex PTSD in eating disorder treatment-seekers: Prevalence and associations with symptom severity

Although childhood trauma and posttraumatic stress disorder (PTSD) have been well-researched in eating disorder epidemiology, prevalence rates are unavailable for complex PTSD (CPTSD). Under recently introduced ICD-11 criteria, individuals with CPTSD have both PTSD symptoms and additional disturbances in self-organization (DSO). Using ICD-11 criteria, this study aimed to determine the prevalence of PTSD and DSO symptoms, diagnostic rates of PTSD and CPTSD, and childhood trauma exposure in eating disorder treatment-seekers. Participants (N = 217) were individuals attending residential, partial hospitalization, and outpatient services who completed measures of eating disorder- and trauma-related symptoms and childhood adverse experiences. One third of participants reported PTSD symptoms, and over half reported DSO symptoms, with probable ICD-11 diagnostic rates of 3.8% for PTSD and 28.4% for CPTSD. CPTSD was significantly more prevalent than PTSD and more common in higher levels of care. Both PTSD and DSO symptom severity were positively correlated with eating disorder symptoms and impairment, rs = .285-.642. DSO symptom severity was a significant and unique explanatory factor of eating disorder severity and impairment. The findings highlight the prevalence of CPTSD in eating disorder populations and the association between DSO symptoms and eating psychopathology independent of PTSD symptoms. Implications are discussed for adjunct treatment approaches for individuals with comorbid eating disorders and PTSD or CPTSD.

The impact of parental acceptance and childhood maltreatment on mental health and physical pain in Burundian survivors of childhood sexual abuse

BACKGROUND

Parental support has been suggested to mitigate mental and physical consequences following childhood sexual abuse (CSA). However, many CSA survivors experience parental rejection post-CSA.

OBJECTIVE

We aimed to understand the impact of abuse-specific parental acceptance on post-traumatic stress disorder (PTSD) and physical pain in Burundian CSA-survivors. We further assessed the significance of parental acceptance among known risk factors for predicting PTSD.

METHODS, PARTICIPANTS, AND SETTINGS

Participants (N = 131, 80.9 % female, mean age 16.21 years) were recruited via primary health care centers for survivors of sexual violence which survivors approached post-CSA. Survivors reported on PTSD symptoms, daytime/nighttime pain, and adverse childhood experiences in semi-structured interviews. Parental acceptance levels were categorized (acceptance, no acceptance, no contact) for mothers and fathers separately. Kruskal-Wallis tests assessed group differences. Conditional random forests (CRF) evaluated the significance of parental acceptance in predicting PTSD symptom severity.

RESULTS

No significant differences regarding PTSD symptoms and physical pain between levels of maternal acceptance were obtained. Pairwise comparisons revealed significant differences in PTSD symptom severity between paternal acceptance and no acceptance (d = 1.04) and paternal acceptance and no contact (d = 0.81). The CRF identified paternal acceptance as important variable for the prediction of PTSD symptom severity. Even though results were less conclusive, medium effect sizes hint at less pain perception within the paternal acceptance group.

CONCLUSIONS

The results highlight paternal acceptance as a potential risk or protective factor regarding psychological and possibly physical well-being in the aftermath of CSA, even in the context of other known risk factors.

Racial discrimination increases the risk for nonremitting posttraumatic stress disorder symptoms in traumatically injured Black individuals living in the United States

Traumatic, life-threatening events are experienced commonly among the general U.S. population, yet Black individuals in the United States (i.e., Black Americans) exhibit higher prevalence rates of posttraumatic stress disorder (PTSD) and more severe symptoms than other populations. Although empirical research has noted a range of symptom patterns that follow traumatic injury, minimal work has examined the role of racial discrimination in relation to PTSD symptom trajectories. The current study assessed racial discrimination and PTSD symptom trajectories at 6 months postinjury across two separate samples of traumatically injured Black Americans (i.e. emergency department (ED)-discharged and hospitalized). Identified PTSD symptom trajectories largely reflect those previously reported (i.e., ED: nonremitting, moderate, remitting, and resilient; hospitalized: nonremitting, delayed, and resilient), although the resilient trajectory was less represented than expected given past research (ED: 55.8%, n = 62; hospitalized: 46.9%, n = 38). Finally, higher racial discrimination was associated with nonremitting, ED: relative risk ratio (RR) = 1.32, hospitalized: RR = 1.23; moderate, ED: RR = 1.18; and delayed, hospitalized: RR = 1.26, PTSD symptom trajectories. Overall, the current findings not only emphasize the inimical effects of racial discrimination but also demonstrate the unique ways in which race-related negative events can impact PTSD symptom levels and recovery across time.

Sex-dependent differences in vulnerability to early risk factors for posttraumatic stress disorder: results from the AURORA study

BACKGROUND

Knowledge of sex differences in risk factors for posttraumatic stress disorder (PTSD) can contribute to the development of refined preventive interventions. Therefore, the aim of this study was to examine if women and men differ in their vulnerability to risk factors for PTSD.

METHODS

As part of the longitudinal AURORA study, 2924 patients seeking emergency department (ED) treatment in the acute aftermath of trauma provided self-report assessments of pre- peri- and post-traumatic risk factors, as well as 3-month PTSD severity. We systematically examined sex-dependent effects of 16 risk factors that have previously been hypothesized to show different associations with PTSD severity in women and men.

RESULTS

Women reported higher PTSD severity at 3-months post-trauma. Z-score comparisons indicated that for five of the 16 examined risk factors the association with 3-month PTSD severity was stronger in men than in women. In multivariable models, interaction effects with sex were observed for pre-traumatic anxiety symptoms, and acute dissociative symptoms; both showed stronger associations with PTSD in men than in women. Subgroup analyses suggested trauma type-conditional effects.

CONCLUSIONS

Our findings indicate mechanisms to which men might be particularly vulnerable, demonstrating that known PTSD risk factors might behave differently in women and men. Analyses did not identify any risk factors to which women were more vulnerable than men, pointing toward further mechanisms to explain women's higher PTSD risk. Our study illustrates the need for a more systematic examination of sex differences in contributors to PTSD severity after trauma, which may inform refined preventive interventions.

Perceived social support and longitudinal trajectories of depression and anxiety in World Trade Center responders

PURPOSE

While severely distressing events are known to affect mental health adversely, some survivors develop only short-lived or no psychiatric symptoms in the aftermath of a disaster. In the WTC Health Program General Responder Cohort (WTCHP GRC) we examined whether social support was protective against the development of depression or anxiety symptoms after the 9/11 WTC attacks and explored in a subsample whether trait resilience moderated this relationship.

METHODS

We analyzed data from 14,033 traditional and 13,478 non-traditional responders who attended at least three periodic health monitoring visits between 2002 and 2019. Linear mixed-effects models were used to examine depression (Patient Health Questionnaire-9; PHQ-9) and anxiety (Generalized Anxiety Disorder screener; GAD-7) scores. In a subsample of 812 participants, we also assessed if the association between social support and symptoms was moderated by an individual's trait resilience level (Connor-Davidson Resilience Scale, CD-RISC).

RESULTS

For both traditional and non-traditional responders, perceived social support around 9/11 was associated with lower levels of depressive (β = - 0.24, S.E. = 0.017, z = - 14.29, p < 0.001) and anxiety symptoms (β = - 0.17, S. E. = 0.016, z = - 10.48, p < 0.001). Trait resilience scores were higher in responders with at least one source of social support during the aftermath of 9/11 compared to those without (mean 71.56, SD 21.58 vs mean 76.64, SD 17.06; β = 5.08, S.E. = 0.36, p < 0.001). Trait resilience moderated the association between social support and depressive (p < 0.001) and anxiety trajectories (p < 0.001) for traditional responders.

CONCLUSION

Our findings suggest that perceived social support around a severely distressing event may have long-term protective effects on symptoms of depression and anxiety.

Longitudinal variation in resilient psychosocial functioning is associated with ongoing cortical myelination and functional reorganization during adolescence

Adolescence is a period of dynamic brain remodeling and susceptibility to psychiatric risk factors, mediated by the protracted consolidation of association cortices. Here, we investigated whether longitudinal variation in adolescents' resilience to psychosocial stressors during this vulnerable period is associated with ongoing myeloarchitectural maturation and consolidation of functional networks. We used repeated myelin-sensitive Magnetic Transfer (MT) and resting-state functional neuroimaging (n = 141), and captured adversity exposure by adverse life events, dysfunctional family settings, and socio-economic status at two timepoints, one to two years apart. Development toward more resilient psychosocial functioning was associated with increasing myelination in the anterolateral prefrontal cortex, which showed stabilized functional connectivity. Studying depth-specific intracortical MT profiles and the cortex-wide synchronization of myeloarchitectural maturation, we further observed wide-spread myeloarchitectural reconfiguration of association cortices paralleled by attenuated functional reorganization with increasingly resilient outcomes. Together, resilient/susceptible psychosocial functioning showed considerable intra-individual change associated with multi-modal cortical refinement processes at the local and system-level.

Differentially expressed heterogeneous overdispersion genes testing for count data

The mRNA-seq data analysis is a powerful technology for inferring information from biological systems of interest. Specifically, the sequenced RNA fragments are aligned with genomic reference sequences, and we count the number of sequence fragments corresponding to each gene for each condition. A gene is identified as differentially expressed (DE) if the difference in its count numbers between conditions is statistically significant. Several statistical analysis methods have been developed to detect DE genes based on RNA-seq data. However, the existing methods could suffer decreasing power to identify DE genes arising from overdispersion and limited sample size, where overdispersion refers to the empirical phenomenon that the variance of read counts is larger than the mean of read counts. We propose a new differential expression analysis procedure: heterogeneous overdispersion genes testing (DEHOGT) based on heterogeneous overdispersion modeling and a post-hoc inference procedure. DEHOGT integrates sample information from all conditions and provides a more flexible and adaptive overdispersion modeling for the RNA-seq read count. DEHOGT adopts a gene-wise estimation scheme to enhance the detection power of differentially expressed genes when the number of replicates is limited as long as the number of conditions is large. DEHOGT is tested on the synthetic RNA-seq read count data and outperforms two popular existing methods, DESeq2 and EdgeR, in detecting DE genes. We apply the proposed method to a test dataset using RNAseq data from microglial cells. DEHOGT tends to detect more differently expressed genes potentially related to microglial cells under different stress hormones treatments.

Trauma Exposure, Social Support and Mental Health in the General Population in Belgium

INTRODUCTION

International research has shown that trauma exposure can lead to mental health disorders and affect social support. However, there is little insight into trauma exposure and its related issues in the general population of Belgium.

METHODS

Secondary cross-sectional data on the general adult population were retrieved from the Belgian Health Interview Survey. Using a representative sample, data were collected on trauma exposure in the past 12 months, and the disclosure of trauma, social support, depressive/anxiety symptoms and background factors were investigated.

RESULTS

In total, 7728 participants were included in this study, and 4.8% (N = 369) reported trauma exposure within the past 12 months. People with trauma exposure (4.8%, N = 369) consistently had more anxiety and depressive symptoms than those without trauma (p < 0.001), and people with multiple trauma exposures had more symptoms than those with a single trauma (p < 0.001). Social support was observed to be lower among those with trauma exposure (p < 0.001), and 17.1% had never disclosed their trauma to anyone. Sexual violence was higher among women (64.5%) and was also the least disclosed form of trauma.

CONCLUSIONS

Trauma exposure is associated with poorer mental health in Belgium. Around a fifth of those who experience trauma do not disclose their trauma, which is the most common after sexual violence.

Self-stigma mediates the relationships between childhood maltreatment and symptom levels of PTSD, depression, and anxiety

Background: Childhood maltreatment is a risk factor for developing multiple forms of psychopathology, including depression, posttraumatic stress disorder (PTSD), and anxiety. Yet, the mechanisms linking childhood maltreatment and these psychopathologies remain less clear.Objective: Here we examined whether self-stigma, the internalization of negative stereotypes about one's experiences, mediates the relationship between childhood maltreatment and symptom severity of depression, PTSD, and anxiety.Methods: Childhood trauma survivors (N = 685, Mage = 36.8) were assessed for childhood maltreatment, self-stigma, and symptoms of depression, PTSD, and anxiety. We used mediation analyses with childhood maltreatment as the independent variable. We then repeated these mediation models separately for childhood abuse and neglect, as well as the different subtypes of childhood maltreatment.Results: Self-stigma significantly mediated the relationship between childhood maltreatment and depression, PTSD, and anxiety symptoms. For sexual abuse - but not physical or emotional abuse - a significant mediation effect of self-stigma emerged on all symptom types. For childhood neglect, self-stigma significantly mediated the relationship between both emotional and physical neglect and all symptom types.Conclusion: Our cross-sectional study suggests that different types of childhood maltreatment experiences may relate to distinct mental health problems, potentially linked to increased self-stigma. Self-stigma may serve as an important treatment target for survivors of childhood abuse and neglect.

On the Effectiveness of Visual Arts Therapy for Traumatic Experiences: A Systematic Review and Meta-Analysis

Arts therapy is a popular intervention used to work through the effects of traumatic experience. We evaluate previous reviews and report a meta-analysis of the effectiveness of arts therapy following trauma for reducing symptoms of PTSD, enhancing positive outcomes (e.g., quality of life) and decreasing negative outcomes (e.g., depression). Database searches identified 21 (N = 868) randomised controlled trials (RCTs). Outcomes were categorised as PTSD specific, positive non-PTSD specific and negative non-PTSD specific. Several moderators were tested: age, diagnosis type, trauma type, intervention instruction, control type, therapy mode and therapy duration. Overall, random-effects analysis indicated that arts therapy was favoured relative to control for positive non-PTSD-specific outcomes (g = 1.53, p < 0.001), but not for negative non-PTSD-specific (p = 0.069) or PTSD-specific outcomes (g = 0.89, p = 0.052). Regression analyses indicated that arts therapy was effective in reducing PTSD-specific outcomes in children (Z = 2.81, df = 1, p = 0.005), positive non-PTSD-specific outcomes in group-based arts therapy (Z = -2.40, df = 1, p = 0.016, I2 = 57.33) and for reducing negative non-PTSD outcomes following acute traumas (e.g., combat-related trauma or sexual abuse) (Q = 10.70, df = 3, p = 0.013, I2 = 77.09). We highlight the need for additional RCTs and standardised protocols to address heterogeneity. Our review provides an important benchmark for gauging the effectiveness of arts therapy in the treatment of trauma.

The effect of a single session of psychological first aid in the emergency department on PTSD and depressive symptoms three months post-intervention: results of a randomised controlled trial

Background: Despite its popularity, evidence of the effectiveness of Psychological First Aid (PFA) is scarce.Objective: To assess whether PFA, compared to psychoeducation (PsyEd), an attention placebo control, reduces PTSD and depressive symptoms three months post-intervention.Methods: In two emergency departments, 166 recent-trauma adult survivors were randomised to a single session of PFA (n = 78) (active listening, breathing retraining, categorisation of needs, assisted referral to social networks, and PsyEd) or stand-alone PsyEd (n = 88). PTSD and depressive symptoms were assessed at baseline (T0), one (T1), and three months post-intervention (T2) with the PTSD Checklist (PCL-C at T0 and PCL-S at T1/T2) and the Beck Depression Inventory-II (BDI-II). Self-reported side effects, post-trauma increased alcohol/substance consumption and interpersonal conflicts, and use of psychotropics, psychotherapy, sick leave, and complementary/alternative medicine were also explored.Results: 86 participants (51.81% of those randomised) dropped out at T2. A significant proportion of participants in the PsyEd group also received PFA components (i.e. contamination). From T0 to T2, we did not find a significant advantage of PFA in reducing PTSD (p = .148) or depressive symptoms (p = .201). However, we found a significant dose-response effect between the number of delivered components, session duration, and PTSD symptom reduction. No significant difference in self-reported adverse effects was found. At T2, a smaller proportion of participants assigned to PFA reported increased consumption of alcohol/substances (OR = 0.09, p = .003), interpersonal conflicts (OR = 0.27, p = .014), and having used psychotropics (OR = 0.23, p = .013) or sick leave (OR = 0.11, p = .047).Conclusions: Three months post-intervention, we did not find evidence that PFA outperforms PsyEd in reducing PTSD or depressive symptoms. Contamination may have affected our results. PFA, nonetheless, appears to be promising in modifying some post-trauma behaviours. Further research is needed.

New social identities in Ukrainian 'refugees': A social cure or social curse?

Experiencing traumatic events often drives profound post-traumatic stress (PTS), but trauma also has the potential to engender positive consequences, such as post-traumatic growth (PTG). Traumatic experiences may also lead to gaining new identities which can have both protective (i.e., social cure) or damaging (i.e., social curse) effects on health and well-being. This study aims to examine the role of new social identities and related social identity resources acquired after war-related experiences (i.e., identification with a new host society and identification as a refugee) in contributing to different trauma trajectories. The sample included 468 participants who left Ukraine due to the war that commenced on February 24th, 2022, and became residents of Ireland or Poland. The findings indicate that identification with the host society was associated with lower PTS and greater PTG. Whereas identification with refugees was related to higher PTS, but it was not directly associated with PTG. Further, the psychological resources derived from these new identities mediated the relationship between identification strength and PTG. This study offers practical insights for interventions targeting refugees in their new countries of residence.

Childhood Maltreatment and Amygdala-Mediated Anxiety and Posttraumatic Stress Following Adult Trauma

Background

Childhood abuse (physical, emotional, and sexual) is associated with aberrant connectivity of the amygdala, a key threat-processing region. Heightened amygdala activity also predicts adult anxiety and posttraumatic stress disorder (PTSD) symptoms, as do experiences of childhood abuse. The current study explored whether amygdala resting-state functional connectivity may explain the relationship between childhood abuse and anxiety and PTSD symptoms following trauma exposure in adults.

Methods

Two weeks posttrauma, adult trauma survivors (n = 152, mean age [SD] = 32.61 [10.35] years; women = 57.2%) completed the Childhood Trauma Questionnaire and underwent resting-state functional magnetic resonance imaging. PTSD and anxiety symptoms were assessed 6 months posttrauma. Seed-to-voxel analyses evaluated the association between childhood abuse and amygdala resting-state functional connectivity. A mediation model evaluated the potential mediating role of amygdala connectivity in the relationship between childhood abuse and posttrauma anxiety and PTSD.

Results

Childhood abuse was associated with increased amygdala connectivity with the precuneus while covarying for age, gender, childhood neglect, and baseline PTSD symptoms. Amygdala-precuneus resting-state functional connectivity was a significant mediator of the effect of childhood abuse on anxiety symptoms 6 months posttrauma (B = 0.065; 95% CI, 0.013-0.130; SE = 0.030), but not PTSD. A secondary mediation analysis investigating depression as an outcome was not significant.

Conclusions

Amygdala-precuneus connectivity may be an underlying neural mechanism by which childhood abuse increases risk for anxiety following adult trauma. Specifically, this heightened connectivity may reflect attentional vigilance for threat or a tendency toward negative self-referential thoughts. Findings suggest that childhood abuse may contribute to longstanding upregulation of attentional vigilance circuits, which makes one vulnerable to anxiety-related symptoms in adulthood.

Defining a screening tool for post-traumatic stress disorder in East Africa: a penalized regression approach

Background

Scalable PTSD screening strategies must be brief, accurate and capable of administration by a non-specialized workforce.

Methods

We used PTSD as determined by the structured clinical interview as our gold standard and considered predictors sets of (a) Posttraumatic Stress Checklist-5 (PCL-5), (b) Primary Care PTSD Screen for the DSM-5 (PC-PTSD) and, (c) PCL-5 and PC-PTSD questions to identify the optimal items for PTSD screening for public sector settings in Kenya. A logistic regression model using LASSO was fit by minimizing the average squared error in the validation data. Area under the receiver operating characteristic curve (AUROC) measured discrimination performance.

Results

Penalized regression analysis suggested a screening tool that sums the Likert scale values of two PCL-5 questions-intrusive thoughts of the stressful experience (#1) and insomnia (#21). This had an AUROC of 0.85 (using hold-out test data) for predicting PTSD as evaluated by the MINI, which outperformed the PC-PTSD. The AUROC was similar in subgroups defined by age, sex, and number of categories of trauma experienced (all AUROCs>0.83) except those with no trauma history- AUROC was 0.78.

Conclusion

In some East African settings, a 2-item PTSD screening tool may outperform longer screeners and is easily scaled by a non-specialist workforce.

Predicting Post-Disaster Post-Traumatic Stress Disorder Symptom Trajectories: The Role of Pre-Disaster Traumatic Experiences

The mental health impact of disasters is substantial, with 30-40% of direct disaster victims developing post-traumatic stress disorder (PTSD). It is not yet clear why some people cope well with disaster-related trauma while others experience chronic dysfunction. Prior research on non-disaster trauma suggests that an individual's history of traumatic experiences earlier in the life course, prior to the disaster, may be a key factor in explaining variability in psychological responses to disasters. This study evaluated the extent to which pre-disaster trauma predicts PTSD trajectories in a sample of Hurricane Katrina survivors followed for 12 years after the storm. Four PTSD trajectories were identified using latent class growth analysis: Resistant (49.0%), Recovery (29.3%), Delayed-Onset (8.0%), and Chronic-High (13.7%). After adjusting for covariates, pre-Katrina trauma had only a small, positive impact on the probability of long-term, chronic Katrina-specific PTSD, and little effect on the probability of the Resistant and Delayed-Onset trajectories. Higher pre-Katrina trauma exposure moderately decreased the probability of being in the Recovery trajectory, in which Katrina-specific PTSD symptoms are initially high before declining over time. When covariates were added to the model one at a time, the association between pre-Katrina trauma and Chronic-High PTSD was attenuated most by the addition of Katrina-related trauma. Our findings suggest that while pre-disaster trauma exposure does not have a strong direct effect on chronic Katrina-specific PTSD, pre-Katrina trauma may impact PTSD through other factors that affect Katrina-related PTSD, such as by increasing the severity of Katrina-related trauma. These findings have important implications for the development of disaster preparedness strategies to diminish the long-term burden of disaster-related PTSD.

Post-traumatic stress disorder: the role of the amygdala and potential therapeutic interventions - a review

Introduction

Post-traumatic stress disorder (PTSD) is a psychiatric disorder triggered by exposure to a life-threatening or sexually violent traumatic event, and is characterized by symptoms involving intrusive re-experiencing, persistent avoidance of associated stimuli, emotional and cognitive disturbances, and hyperarousal for long periods after the trauma has occurred. These debilitating symptoms induce occupational and social impairments that contribute to a significant clinical burden for PTSD patients, and substantial socioeconomic costs, reaching approximately $20,000 dollars per individual with PTSD each year in the US. Despite increased translational research focus in the field of PTSD, the development of novel, effective pharmacotherapies for its treatment remains an important unmet clinical need.

Observations

In this review, we summarize the evidence implicating dysfunctional activity of the amygdala in the pathophysiology of PTSD. We identify the transient receptor potential canonical (TRPC) ion channels as promising drug targets given their distribution in the amygdala, and evidence from animal studies demonstrating their role in fear response modulation. We discuss the evidence-based pharmacotherapy and psychotherapy treatment approaches for PTSD.

Discussion

In view of the prevalence and economic burden associated with PTSD, further investigation is warranted into novel treatment approaches based on our knowledge of the involvement of brain circuitry and the role of the amygdala in PTSD, as well as the potential added value of combined pharmacotherapy and psychotherapy to better manage PTSD symptoms.

Development of a stepped care intervention model of evidence-based interventions for the management of posttraumatic stress in the Belgian Police

Background: Police officers are frequently exposed to a wide variety of potentially traumatic events (PTE) and are therefore at a considerable risk of developing posttraumatic stress disorder (PTSD). Previous research estimated the point prevalence of PTSD in Belgian police officers at 7.4%, significantly higher than in the general population. An effective organisational strategy to manage posttraumatic stress is essential.Objective: We aimed to develop a novel organisational approach regarding traumatic stress for Belgian police, combining evidence-based strategies for the prevention and treatment of posttraumatic stress in a stepped care intervention model.Method: In a broad development process, we combined scientific literature, case studies of best practices from other police organisations with insights gathered from a number of expert panels, thematic working groups and feedback groups.Results: A comprehensive stepped care intervention model was developed, consisting of evidence-based interventions for the prevention and treatment of posttraumatic stress.Conclusions: The intervention model is a promising organisational strategy for the management of posttraumatic stress in police organisations based on evidence-based interventions. Its effectiveness will be studied in the coming years.

The effect of the sense of Community on Depression, Anxiety, and Stress: the mediation role of a balanced time perspective

PURPOSE

Social context and time are two dimensions within which our entire existence is embedded. Therefore, prompting a positive set of attitudes and beliefs towards these elements is fundamental for individuals' psychological well-being. Currently, there is limited understanding regarding the interplay between the sense of community and time perspective in relation to psychological distress. The present study aims, at investigating the effects that the sense of community and time perspective have on the levels of anxiety, depression, and stress. Particular attention has been dedicated to testing whether the effect of sense of community on anxiety, depression, and stress is mediated by the deviation from a balanced time perspective.

METHODS

To accomplish our purposes, we asked 352 participants to complete an online survey and respond to the Depression, Anxiety, Stress Scale (DASS-21), the Zimbardo Time Perspective Inventory (ZTPI), and the Multi-Dimensional Sense of Community Scale (MTSOCS). From these scales, we obtained the scores for anxiety, depression, and stress as well as a general score for the sense of community and the deviation from a balanced time perspective. We computed three General Linear Mediation Models, one for each scale of the DASS-21.

RESULTS

The results showed that the relationship between sense of community and psychological distress was mediated by the deviation from a balanced time perspective extending previous findings and enriching the existing literature on time perspective.

CONCLUSION

The results described so far could be applied to build a series of interventions aimed at promoting psychological well-being in the general population. Considering our findings, we suggest that individuals' health could be promoted by both improving their sense of community, which in turn would decrease their levels of stress, and by restructuring their time perspective when it became dysfunctional and unbalanced.

Associations among posttraumatic stress disorder symptoms, life satisfaction, and well-being comparisons: A longitudinal investigation

Many individuals who encounter potentially traumatic events go on to develop symptoms of posttraumatic stress disorder (PTSD). Research suggests that survivors of traumatic events frequently compare their current well-being to different standards; yet, knowledge regarding the role of comparative thinking in well-being is limited to a few cross-sectional studies. We therefore examined the temporal associations among aversive well-being comparisons (i.e., comparisons threatening self-motives), PTSD symptoms, and life satisfaction in individuals exposed to traumatic events. Participants (N = 518) with a trauma history completed measures of PTSD symptoms and life satisfaction, as well as the Comparison Standards Scale for Well-being (CSS-W), at assessment points 3 months apart. The CSS-W assesses the frequency, perceived discrepancy, and affective impact of aversive social, temporal, counterfactual, and criteria-based comparisons related to well-being. All participants reported having engaged in aversive well-being comparisons during the last 3 weeks. Comparison frequency emerged as a significant predictor of PTSD symptoms, β = .24, beyond baseline PTSD symptom severity. Life satisfaction contributed unique variance to the comparison process by predicting comparison frequency, β = -.18; discrepancy, β = -.24; and affective impact, β = .20. The findings suggest that frequent aversive comparisons may lead to a persistent focus on negative aspects of well-being, thereby exacerbating PTSD symptoms, and further indicate that comparison frequency, discrepancy, and affective impact are significantly influenced by life satisfaction. Taken together, the findings support the need for a thorough examination of the role of comparative thinking in clinical populations, which may ultimately help improve clinical care.

Can mindfulness-based interventions reduce PTSD symptoms? An umbrella review

Post-traumatic stress disorder (PTSD) is a debilitating, often chronic condition with substantial cross-national lifetime prevalence. Although mindfulness-based interventions (MBIs) may help reduce PTSD symptoms, efficacy results are inconsistent. Despite many systematic reviews (SRs) examining MBIs for PTSD, SR quality has been neither evaluated nor synthesized. We conducted an umbrella review to summarize and evaluate existing evidence regarding MBIs for PTSD, identifying 69 SRs (27 meta-analyses), consisting of 83 primary studies. Using AMSTAR2 (a valid SR quality assessment tool), we evaluated each SR on key domains relevant to methodological rigor and rated the confidence of inferences. Results found SRs were 65.2% non-rigorous, 27.5% likely rigorous, and 7.2% rigorous; common limitations included inadequate risk of bias assessment, extractions not completed in duplicate, and lack of pre-registration, highlighting the need for higher quality SRs. We then performed a meta-meta-analysis to estimate the efficacy of MBIs to reduce PTSD symptoms, yielding a medium effect size (SMD=0.41, p < .001), derived from 22 meta-analyses (with replicable data) and 35 unique articles. Analyses were consistent across control conditions and MBI type (first-generation/narrow [i.e., MBIs with well-established protocols]) versus broad (i.e., other MBI types), comparable with second-line treatments (e.g., pharmacotherapy). Findings were narratively synthesized; areas for methodological improvements in MBI research were identified.

Effects of mindfulness-based cognitive therapy for Chinese adults with PTSD symptoms: protocol for a randomised controlled trial

INTRODUCTION

Emerging evidence supports mindfulness as a potential psychotherapy for post-traumatic stress disorder (PTSD). Individuals with subthreshold PTSD experience significant impairment in their daily life and functioning due to PTSD symptoms, despite not meeting the full diagnostic criteria for PTSD in DSM-5. Mindfulness skills, including non-judgmental acceptance, attentional control and openness to experiences may help alleviate PTSD symptoms by targeting characteristics such as intensified memory processing, dysregulated hyperarousal, avoidance, and thought suppression. This trial aims to test the effects of mindfulness-based cognitive therapy (MBCT) when compared to an active control.

METHOD AND ANALYSIS

This 1:1 randomised controlled trial will enroll 160 participants with PTSD symptoms in 2 arms (MBCT vs. Seeking Safety), with both interventions consisting of 8 weekly sessions lasting 2 h each week and led by certified instructors. Assessments will be conducted at baseline (T0), post-intervention (T1), and 3 months post-intervention (T2), with the primary outcome being PTSD symptoms measured by the PTSD checklist for DSM-5 (PCL-5) at T1. Secondary outcomes include depression, anxiety, attention, experimental avoidance, rumination, mindfulness, and coping skills. Both intention-to-treat and per-protocol analyses will be performed. Mediation analysis will investigate whether attention, experimental avoidance, and rumination mediate the effect of mindfulness on PTSD symptoms.

DISCUSSION

The proposed study will assess the effectiveness of MBCT in improving PTSD symptoms. The findings are anticipated to have implications for various areas of healthcare and contribute to the enhancement of existing intervention guidelines for PTSD.

Exhausting, but necessary: the lived experience of participants in an intensive inpatient trauma treatment program

Background

Intensive inpatient treatment programs have shown robust results in the treatment of post-traumatic stress disorder (PTSD). How patients experience this treatment program and what changes they experience as a result of the treatment have, however, only scarcely been explored through qualitative studies.

Objective

This study aimed to explore the lived experience of participants in an intensive inpatient trauma treatment program. Our research questions were as follows: how do patients experience intensive trauma-focused treatment? How do they experience possible changes related to participating in the treatment program?

Methods

Six patients diagnosed with PTSD with significant comorbidities, who recently participated in an intensive 2-week (4 + 4 days) inpatient trauma treatment program with prolonged exposure (PE), eye movement desensitization and reprocessing (EMDR), and therapist rotation (TR), were interviewed with a semi-structured qualitative interview. Transcripts were analyzed using a thematic analysis approach.

Results

Our analysis resulted in five main themes: (1) the need to feel safe; (2) the benefits of many and different therapeutic encounters; (3) variable experience with elements of treatment; (4) intensity; and (5) experienced change. Our results suggest that feeling safe within the framework of the treatment program facilitated the treatment process. Many and different therapeutic encounters, both through TR and with ward staff, contributed to experienced change. All participants described the intensity as facilitative to trauma processing. However, most participants also describe often feeling too overwhelmed to benefit from all elements of the treatment program.

Conclusions

Our findings suggest that participants experience the overall treatment program as beneficial and contributing to experienced change. Participants described the intensity of the program as exhausting, but necessary. Most did, however, report at times of being too overwhelmed to benefit from elements of the program. Consequently, our results prompt us to question the optimal level of intensity.

Comparing the effectiveness of narrative therapy and EMDR-GTEP protocols in the treatment of post-traumatic stress in children exposed to humanitarian crises

Background

The mental health of children living in humanitarian crisis situations is a major issue. Post-traumatic stress disorder (PTSD) causes great psychological suffering and has negative consequences on children's development. The aim of the study was to analyze retrospective data collected in a mental health and psychosocial support program for children in the Central African Republic, and to compare results of two trauma-focused treatment interventions: the narrative protocol Action contre la Faim (ACF)/KONO; and the EMDR-based Group Trauma Episode Protocol (G-TEP). Both protocols are proposed in a group setting and led by paraprofessionals.

Methods

In the program, 884 children attended a psychoeducation session and after that, 661 children (290 for ACF/KONO and 371 for G-TEP) benefited from all treatment sessions. PTSD was measured by the Children's Revised Impact of Event Scale (CRIES-8). General distress was measured by the Child Psychosocial Distress Screener (CPDS). Data were collected before and after treatment, and measured 5 months after the end of treatment for 185 children.

Results

Participants in the ACF/KONO group show a significant reduction on CRIES-8 (t = 44.8; p < 0.001, effect size = 2.63) and CPDS (t = 38.2; p < 0.001, effect size = 2.24). Participants to the G-TEP protocol show a significant effect with reduced scores on the CRIES-8 (t = 49.2; p < 0.001, effect size = 2.55) and CPDS (t = 57.2; p < 0.001, effect size = 2.97). A Student's t-test comparing the ACF/KONO and G-TEP groups shows no significant difference between the two types of treatment between pre- and post-treatment CRIES-8 scores (t = 1.744; p = 0.514, effect size = 0.040) and CPDS scores (t = 1.688; p = 0.092, effect size = 0.323). An analysis of the follow-up data for the 185 children shows that the effects of both protocols are maintained over time with mean scores after treatment and follow-up below the clinical cut-off for both CPDS (<8) and CRIES-8 (<17).

Conclusions

Both protocols have been shown to be effective in reducing traumatic symptoms in children exposed to conflict; they can be conducted by paraprofessionals and used in humanitarian crisis situations.
