Interacting with a friend after a trauma film reduces anxiety and intrusive memories.

Interpersonal factors have been linked with psychological adjustment to trauma, but how interpersonal factors influence trauma response is still unclear. Experimental paradigms such as the trauma film paradigm offer a valuable approach for studying this complex dynamic. However, few studies have used the trauma film paradigm to examine the interpersonal context of trauma response, and no studies have incorporated friends into the trauma film paradigm. The purpose of the current study was to examine how inclusion of a friend influenced reactions to a trauma analog. One hundred young adult females were randomized to watch a brief stressful film of a sexual assault either with or without a friend and the Friend Present condition was given an opportunity to interact following the film. Participants were evaluated on distress during the film, skin conductance, anxiety and negative affect immediately postfilm (preinteraction) and 5 minutes later (postinteraction), and intrusive memories over a three-day period. No differences were found between conditions on skin conductance or subjective distress during the film. However, the Friend Present condition experienced a greater reduction in state anxiety from preinteraction to postinteraction and greater decreases in intrusive memories over the three-day period. Findings show the inclusion of a friend mitigated trauma-related stress reactions and suggest that interacting with a friend aided in adaptive processing of the stressor. Findings indicate that additional work is needed to examine how platonic relationships can be targeted to improve prevention and intervention efforts in trauma-related outcomes.

Criterion A and Non-Criterion A Racial Discrimination Experiences, Posttraumatic Stress Symptoms, and Posttraumatic Cognitions Among Black or African Americans.

Racial discrimination is an unfortunately common experience for Black Americans with detrimental physical and mental health consequences. Prior research has established an association between discrimination and posttraumatic stress symptoms (PTSS); yet, trauma-related cognitions have not been studied. The majority of the existing empirical work in this area has not examined specific forms of discrimination experiences, despite potential key differences in these adversities. Relatedly, some forms of discrimination constitute "traumatic" events as defined by Criterion A for PTSD in the DSM-5 while others do not, and these distinctions have also been overlooked. Thus, the present study aimed to (a) examine discrimination, including specific types, in relation to PTSS and posttraumatic cognitions and (b) investigate whether Criterion A and non-Criterion A discrimination experiences were tied to PTSS and trauma-related thoughts. Participants were 172 undergraduate students who identified as Black or African American (Mage = 25.11, SD = 8.25, range = 18-56; 84.9% female). Results indicated that while cumulative trauma was unrelated to PTSS, discrimination experiences were linked with higher PTSS and negative posttraumatic cognitions. Specifically, avoidance discrimination experiences were associated with both outcomes. Criterion A discrimination events were not tied to PTSS. These findings support previous research showing a link between racial discrimination and trauma-related outcomes. In addition, the results suggest that avoidance discrimination, while not classified as "traumatic," may have an important contribution to PTSS and posttraumatic cognitions among Black individuals. The study underscores the need to address racial discrimination experiences, including microaggressions, within a traumatic stress context.

Perspectives on elder mistreatment screening and responding in emergency departments: A qualitative study with survivors.

Elder Mistreatment (EM) occurs in approximately 10% of older adults and is associated with trauma-related outcomes including depression, anxiety, posttraumatic stress disorder, and early mortality. Low screening and older adult self-reporting, especially within emergency departments, represent missed opportunities for identify and mitigate future EM occurrences and consequences. To date, no studies have obtained EM survivors' perspectives on EM screening and response practices in emergency departments. Semi-structured interviews with 19 EM survivors of those with Adult Protective Services validated EM were completed in older adults' homes. The Elder Mistreatment Emergency Department Screening and Response Tool (EM-SART) was used to guide the interview questions. All interviews were recorded, transcribed, and analyzed using qualitative thematic analyses. The participants were mostly female (63%) and white (58%) with an average age of 74 years. Physical abuse accounted for 67% of the EM incidents. Three themes emerged indicating the survivor preference for (1) building rapport and approaching the older adult with compassion and care, (2) setting the context before asking the EM questions, and (3) allowing mutuality, collaborative work, and shared decision-making during the response. Older adults are agreeable and willing to self-report and actively engage in the EM screening and response practices in the emergency department if trauma-informed care principles are utilized.

Cohort Profile: The China Severe Trauma Cohort (CSTC).

We sought to establish a prospective hospital-based cohort, featuring detailed multidimensional data of trauma patients with active follow-ups, which can be a reliable data source for all studies focusing on the effects or underlying mechanistic pathways of environmental and biological factors on multiple interested trauma-related outcomes, particularly the incidence and trajectory of trauma-related psychopathology, in a Chinese population. The China Severe Trauma Cohort (CSTC) enrolled all traumatized individuals aged 12 to 80 years admitted to the Trauma Center of West China Hospital between March 1st, 2020 and July 8th, 2022. The bio-sample and detailed questionnaire data were collected at recruitment, and phone/internet follow-ups were scheduled at 1, 3, 6, and 12 months after the baseline. Long-term health outcomes are planned to be obtained from administrative databases through data linkage. A total of 2,500 trauma patients were enrolled (response rate = 87.1%) with an average age of 46.01 years, and most of the participants were males (62.6%). The proportions of participants with blood and fecal sample collected at baseline were 93.8% and 66.3%, respectively. As of August 31st, 2022, the follow-up rate was 90.0%, 77.0%, 76.5%, and 89.0% for 1-, 3-, 6-, and 12-month follow-ups, respectively. Fall/wrench (47.6%) and traffic accident (26.2%) were the top causes of current trauma. The most common psychopathology at recruitment was sleep disturbance (39.4%), followed by depression (22.6%), anxiety (18.2%), and acute stress reaction (7.8%), all of which showed recovering trajectories during the follow-up period, particularly the first 3 months after baseline. CSTC provides a platform with multidimensional data to study both short-term and long-term trauma-related health consequences, prompting early identification and intervention for individuals with high risk of health decline after trauma exposures.

Comparison of ACE-IQ and CTQ-SF for child maltreatment assessment: Reliability, prevalence, and risk prediction

BackgroundChild maltreatment has profound effects on mental health. The Childhood Trauma Questionnaire Short Form (CTQ-SF) and the Adverse Childhood Experiences International Questionnaire (ACE-IQ) are commonly used retrospective assessment tools for evaluating child maltreatment. ObjectiveThis study aims to conduct a comprehensive comparison of the CTQ-SF and ACE-IQ, encompassing internal consistency, prevalence, and the predictive efficacy of trauma-related outcomes. It also seeks to enhance the scoring method of ACE-IQ based on the established comparability between the two instruments. Participants and setting1484 college students from northern China were recruited, assessing demographic characteristics and outcomes related to traumatic experiences, including post-traumatic stress disorder (PTSD), complex post-traumatic stress disorder (CPTSD), borderline personality disorder (BPD), anxiety, and depression. MethodsA contingency correlation analysis was performed to evaluate the degree of agreement between the CTQ-SF and ACE-IQ. Binary logistic regression models were utilized to compare the predictive capabilities of distinct instruments. ResultsCTQ-SF and ACE-IQ instruments display favorable internal consistency and notable correlations across shared categories. However, the predictive relationships between trauma type and adverse outcomes are inconsistent across instruments. The ACE-IQ, encompassing 13 trauma categories, demonstrate a lower AIC and BIC index, indicating a superior model fit for elucidating outcomes. ConclusionThis study introduces a scoring methodology for ACE-IQ, improving the comparability of the two measures and emphasizing the importance of capturing the full range of maltreatment types a child may have experienced. These findings have significant implications for clinical and epidemiological research, providing valuable insights for understanding the impact of child maltreatment.

Associations between mindfulness and mental health after collective trauma: results from a longitudinal, representative, probability-based survey

ABSTRACT Background/objectives Trait mindfulness (TM) may protect against post-trauma mental health ailments and related impairment. Few studies have evaluated this association in the context of collective traumas using representative samples or longitudinal designs. Design/method We explored relationships between TM and collective trauma-related outcomes in a prospective, representative, probability-based sample of 1846 U.S. Gulf Coast residents repeatedly exposed to catastrophic hurricanes, assessed twice during the COVID-19 outbreak (Wave 1: 5/14/20–5/27/20; Wave 2: 12/21/21–1/11/22). Generalized estimating equations examined longitudinal relationships between TM, COVID-19-related fear/worry, hurricane-related fear/worry, global distress, and functional impairment; ordinary least squares regression analyses examined the cross-sectional association between TM and COVID-19-related posttraumatic stress symptoms (PTSS) at Wave 1. Event-related stressor exposure was explored as a moderator. Results In covariate-adjusted models including pre-event mental health ailments and demographics, TM was negatively associated with COVID-19-related fear/worry, hurricane-related fear/worry, global distress, and functional impairment over time; in cross-sectional analyses, TM was negatively associated with COVID-19-related PTSS. TM moderated the relationship between COVID-19 secondary stressor exposure (e.g., lost job/wages) and both global distress and functional impairment over time. Conclusions Results suggest TM may buffer adverse psychosocial outcomes following collective trauma, with some evidence TM may protect against negative effects of secondary stressor exposure.

Relationship of Maternal Age and Adverse Childhood Experiences (ACEs) with Traumatic Sequelae in Commercially Sexually Exploited Youth

The impact of early maternal age on several outcomes (e.g., mental health issues, delinquency, aggression, impulsivity, victimization, and interpersonal difficulties) has been studied since the late 1980s. Research has demonstrated links between exposure to adverse childhood experiences (ACEs) and trauma-related outcomes such as substance abuse, interpersonal and self-directed violence, and sexual risk-taking, to name a few. The current study analyzed the incidence of ACE exposure and mental health outcomes (e.g., suicidal behaviors or self-harm, psychiatric hospitalizations, and substance use) as related to early maternal age in youth known to have experienced trafficking or sexual abuse. General demographics and incidence of various experiences and clinical presentations (e.g., ACE exposure, age of mother at birth of youth, and age at first birth), and history of self-harm, substance use, and psychiatric hospitalization, were examined in a sample of 225 youth referred for services subsequent to experiences of sex trafficking or exploitation. Relationships between ACE exposure and maternal age related to mental health outcomes were also examined. Trafficked and exploited youth reported rates of ACE exposure and poor mental health outcomes at far greater rates than the general population. Significant findings were related to early maternal age and engaging in self-harm or suicidal behaviors. Previously anticipated mediational analyses were not conducted due to the sample size and lack of correlations. Findings highlight the significant ACE exposure and high needs of exploited, trafficked, and abused youth and related mental health outcomes, emphasizing the need for early and comprehensive preventive and therapeutic interventions.

Foot and Ankle Outcome Instruments: Missing the Target

Although developing PROMs is arduous and measuring their psychometric characteristics is even more so, the number of available PROMs has grown dramatically in the foot and ankle community over the past few years. The psychometric properties of foot and ankle PROMs vary considerably, which could explain why there are so many of them used in the literature. This review aims to shed light on the most commonly used PROMs in foot and ankle literature and assess the evidence supporting their use. In this study, very limited evidence was found to support the use of most of the commonly used PROMs in foot and ankle literature, and no evidence was found that supports the use of the most common tool, the AOFAS Clinical Rating System. The quality of the studies examining PROMs was also questioned. Prior to making a conclusive determination regarding each instrument, however, additional research on the evidence is necessary. It is extremely challenging to perform systematic reviews comparing data across foot and ankle studies, and it is almost impossible to pool such data into high-quality meta-analyses. So, we need a foot and ankle score for measuring trauma-related outcomes, a score for measuring elective procedure outcomes, and a score for measuring pediatric foot and ankle.

Use of Bayesian Statistics to Reanalyze Data From the Pragmatic Randomized Optimal Platelet and Plasma Ratios Trial

Frequentist statistical approaches are the most common strategies for clinical trial design; however, bayesian trial design may provide a more optimal study technique for trauma-related studies. To describe the outcomes of bayesian statistical approaches using data from the Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) Trial. This quality improvement study performed a post hoc bayesian analysis of the PROPPR Trial using multiple hierarchical models to assess the association of resuscitation strategy with mortality. The PROPPR Trial took place at 12 US level I trauma centers from August 2012 to December 2013. A total of 680 severely injured trauma patients who were anticipated to require large volume transfusions were included in the study. Data analysis for this quality improvement study was conducted from December 2021 and June 2022. In the PROPPR Trial, patients were randomized to receive a balanced transfusion (equal portions of plasma, platelets, and red blood cells [1:1:1]) vs a red blood cell-heavy strategy (1:1:2) during their initial resuscitation. Primary outcomes from the PROPPR trial included 24-hour and 30-day all-cause mortality using frequentist statistical methods. Bayesian methods were used to define the posterior probabilities associated with the resuscitation strategies at each of the original primary end points. Overall, 680 patients (546 [80.3%] male; median [IQR] age, 34 [24-51] years, 330 [48.5%] with penetrating injury; median [IQR] Injury Severity Score, 26 [17-41]; 591 [87.0%] with severe hemorrhage) were included in the original PROPPR Trial. Between the groups, no significant differences in mortality were originally detected at 24 hours (12.7% vs 17.0%; adjusted risk ratio [RR], 0.75 [95% CI, 0.52-1.08]; P = .12) or 30 days (22.4% vs 26.1%; adjusted RR, 0.86 [95% CI, 0.65-1.12]; P = .26). Using bayesian approaches, a 1:1:1 resuscitation was found to have a 93% (Bayes factor, 13.7; RR, 0.75 [95% credible interval, 0.45-1.11]) and 87% (Bayes factor, 6.56; RR, 0.82 [95% credible interval, 0.57-1.16]) probability of being superior to a 1:1:2 resuscitation with regards to 24-hour and 30-day mortality, respectively. In this quality improvement study, a post hoc bayesian analysis of the PROPPR Trial found evidence in support of mortality reduction with a balanced resuscitation strategy for patients in hemorrhagic shock. Bayesian statistical methods offer probability-based results capable of direct comparison between various interventions and should be considered for future studies assessing trauma-related outcomes.

Who discovers the firearm suicide decedent: an epidemiologic characterization of survivor-victims

BackgroundSuicide is the tenth leading cause of death in the United States, with over half of cases involving firearms. Despite research indicating negative effects of exposure to suicide, there is little research on who typically finds the body of the suicide decedent. Understanding who finds the body of the suicide decedent may be important to understand trauma and mental health effects.FindingsOf the 332 people who died by suicide in El Paso County, Colorado, 182 (55%) used firearms. Those who died by firearm suicide were more likely to be male (83.5% vs. 67.3%) have military affiliation (39.0% vs. 19.3%) and were less likely to have a known mental health diagnosis (47.3% vs. 64.7%) compared to those who died from other means. Most suicide decedents were found by a family member or friend (60.2%). The remaining decedents were found by a stranger/acquaintance (21.0%) or a first responder (22.4%) One-fifth of suicides involved forced witnessing (19%) and the majority were already deceased when the body was discovered (73.2%).ConclusionsWhile most suicide decedents are discovered by a family member or a friend, it is unknown what the bereavement and trauma-related outcomes are among people who discover a suicide decedent who has died by violent means, especially by firearms. Further studies exploring who discovers suicide decedents and targeted postvention strategies for supporting impacted family, friends, first responders, and strangers are needed.

How Does Parenthood Moderate Paths Between Personal and Community Resources and Distress following Collective Trauma?

This study examines the moderating role of parenthood in associations between personal and community resources and psychological distress and somatization following collective exposure to security threats. The research questions were guided by Terror Management Theory that posits that parenthood involves heightened anxiety when children are in danger yet may also provide an existential resource that can reduce the individuals' distress. The study was conducted following the 2014 Israel-Gaza conflict and included 1014 Israelis. The participants completed a questionnaire assessing levels of trauma exposure (the predictors), sense of mastery (personal resource), engagement in community activities and trust in leaders (community resources), and psychological distress and somatization (the outcomes). Results indicated that parenthood moderated several associations between trauma exposure and personal and community resources as well as paths between these resources and psychological distress. In almost all these cases, these paths were statistically significant only among parents in two different directions. Parenthood was associated with more psychological distress through lower sense of mastery and greater engagement in community activities. On the other hand, parenthood was related to lower psychological distress through greater trust in local leaders. In addition, only among parents, lower levels of mastery mediated the association between trauma exposure and somatization. These results offer significant implications for practitioners. Although parents and non-parents can be similarly affected by trauma exposure with respect to trauma-related outcomes, the way to assist them to reduce these negative outcomes should be conducted through different paths involving their personal and community resources.

The role of time since trauma on treatment outcomes of veterans in two intensive posttraumatic stress disorder treatment programs.

Research on the impact of time since trauma (TST) on posttraumatic stress disorder (PTSD) treatment outcomes lacks consensus and has not been examined in cognitive processing therapy (CPT)-based intensive PTSD treatment programs (ITPs). Furthermore, little is known about how TST impacts other trauma-related outcomes, such as depressive symptoms and negative posttrauma cognitions. We examined whether TST predicted severity and changes in PTSD and depressive symptoms and negative posttrauma cognitions, controlling for trauma type (combat or military sexual trauma), age, sex, and race, in two separate samples of veterans with PTSD who completed 2-week (n = 132) or 3-week (n = 407) CPT-based ITPs. In the 3-week sample, PTSD symptom reduction differed based on TST; however, these differences lacked clinical significance, TST x Time R2 b = .002, and were not replicated in the 2-week sample, R2 b < .001. TST did not significantly predict depressive symptoms, R2 b = .005, or negative posttrauma cognition severity or changes, R2 b = .002, in the 3-week sample. In the 2-week sample, linear mixed-effects models indicated that TST also did not significantly predict PTSD or depressive symptoms, R2 b s < .001, or negative posttrauma cognition severity or changes, R2 b s = .002. These findings suggest that TST is not a clinically relevant predictor of PTSD symptoms, depressive symptoms, or negative posttrauma cognitions among individuals engaged in CPT-based ITPs. Future research should investigate the association between TST and trauma-related outcomes in more trauma type- and age-diverse samples within different intensive treatment settings.

Are trauma surgical societies adequately addressing mental health after injury?

BackgroundSurvivors of physical trauma, their home caregivers, and their medical providers all have an increased risk of developing psychological distress and trauma-related psychiatric disease. The purpose of this study was to describe the frequency and change over time of trauma society research presentations regarding mental health to identify opportunities for growth. MethodsArchives from 2018 to 2020 from the American Association for the Surgery of Trauma, the Eastern Association for the Surgery of Trauma, and the Western Trauma Association were reviewed. The studies that measured mental illness, psychosocial distress, and other psychosocial factors were assessed: for (1) the use of patient-reported outcome measures ; (2) the association of psychosocial variables with outcomes; and (3) the interventions investigated. Change over time was assessed using χ2 analysis. ResultsOf 1,239 abstracts, 57 (4.6%) addressed at least 1 mental health-related factor. Mental health was more frequently studied over time (2018 [3.2%]; 2019 [3.5%]; 2020 [7.7%]; P = .003). The most frequently measured factors were post-traumatic stress disorder, quality of life, general mental health, and depression. Seventeen (29.8%) abstracts addressed substance abuse, most commonly opioid abuse. Seven (12.3%) abstracts measured mental health in caregivers or medical providers. Patient-reported outcome measures were used in 32 studies (56.1%). Two-thirds of studies reported findings suggesting that mental illness impairs trauma-related outcomes. Only 5 (8.8%) investigated interventions designed to reduce adverse outcomes. ConclusionAlthough academic discussion of mental health after trauma increased from 2018 to 2020, the topic remains a limited component of annual programs, patient-reported outcome measures remain underutilized, and intervention studies are rare.

The Tutor of Resilience Program with Children Who Have Experienced Maltreatment: Mothers’ Involvement Matters

Resilience is a dynamic process involving the presence and interaction of personal and environmental factors that modify the impact of adversity. Resilience-building interventions are therefore important for improving trauma-related outcomes in children and caregivers exposed to adversity. This study examines the impact of the Tutor of Resilience (TOR) program on beneficiaries’ trauma-related symptoms and on mother–child interactions in a group of children exposed to maltreatment (N = 186; mean age = 11.95; SD = 2.50). Assessments were completed at baseline and post-intervention. RM-ANOVAs indicated significant improvements for most trauma symptoms (anxiety, anger, post-traumatic stress, and disassociation, but not depression) in the intervention group relative to a control group (N = 88; mean age = 10.76; SD = 2.57), and indicated further improvements to anxiety and dissociation for the intervention group when mothers were involved. Mother–child interactions also improved over time, as did their overall trauma symptoms and distress. Findings support the effectiveness of the ToR, especially when involving mothers.

MEG neural signature of sexual trauma in women veterans with PTSD.

Previous research has documented the utility of synchronous neural interactions (SNI) in classifying women veterans with and without posttraumatic stress disorder (PTSD) and other trauma-related outcomes based on functional connectivity using magnetoencephalography (MEG). Here, we extend that line of research to evaluate trauma-specific PTSD neural signatures with MEG in women veterans. Participants completed diagnostic interviews and underwent a task-free MEG scan from which SNI was computed. Thirty-five women veterans were diagnosed with PTSD due to sexual trauma and sixteen with PTSD due to non-sexual trauma. Strength of SNI was compared in women with and without sexual trauma, and linear discriminant analysis was used to classify the brain patterns of women with PTSD due to sexual trauma and non-sexual trauma. Comparison of SNI strength between the two groups revealed widespread hypercorrelation in women with sexual trauma relative to those without sexual trauma. Furthermore, using SNI, the brains of participants were classified as sexual trauma or non-sexual trauma with 100% accuracy. These findings bolster evidence supporting the utility of task-free SNI and suggest that neural signatures of PTSD are trauma-specific.

Psychological distress, professional burnout, and trauma in Palestinian health care helpers: A two-wave quantitative longitudinal study.

The aim of this longitudinal study was to model the cumulative network of associations between trauma-related symptoms, professional burnout, and psychological distress in health care practitioners working in emergency settings. The research was conducted with Palestinian health care helpers (N = 60) operating in Gaza and the West Bank. The study variables were evaluated via repeated quantitative self-report questionnaires collected in two waves and the associations among them were estimated using structural equation modeling, bootstrap methods, and Monte Carlo simulation. The longitudinal structural model offered a good fit for the data (χ²(114) = 161.4, p = .02, NC = 1.42, nonnormed fit index [NNFI] = .950, comparative fit index [CFI] = .951, root mean square error of approximation [RMSEA] = .079), in support of the notion that trauma-related outcomes and professional burnout may be associated with mental health across different professional groups. Specifically, trauma-related symptoms wielded a direct effect on professional burnout (β = .28) and psychological distress (β = .11) at T0. Trauma-related symptoms were found to be more strongly associated with professional burnout (β = .40) than with psychological distress (β = .03) at T1. Emergency workers operating in an environment marked by instability and ongoing risk need to draw on sources of resistance and resilience to protect their mental health. We discuss both the clinical implications of these findings and future lines of inquiry. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Scoring the Life Events Checklist: Comparison of three scoring methods.

Prior trauma history is a reliable and robust risk predictor for PTSD development. Obtaining an accurate measurement of prior trauma history is critical in research of trauma-related outcomes. The Life Events Checklist (LEC) is a widely used self-report measure of trauma history that categorizes events by the proximity to trauma exposure; however, the field has published multiple scoring methods when assessing the LEC. Herein, we propose a novel scoring procedure in which total scores from the LEC are weighted according to the proximity of trauma exposure with "experienced" events weighted most and "learned about" events weighted least. The utility of this weighted score was assessed in two traumatically-injured civilian samples and compared against previously published scoring methods, including a nonweighted score including all events experienced, witnessed, and learned about, as well as a score consisting of only experienced events. Results indicated the standard total score was most reliable, followed by the weighted score. The experienced events score was least reliable, but the best predictor of future PTSD symptoms. One method to balance the predictive strength of experienced events and the excellent reliability of a total LEC score, is to adopt the newly proposed weighted score. Future use of this weighted scoring method can provide a comprehensive estimate of lifetime trauma exposure while still emphasizing the direct proximity of experienced events compared with other degrees of exposure.

Using Mixed Methods Integration to Evaluate the Structure of Help-Seeking Barriers Scale: A Survivor-Centered Approach.

Despite the high prevalence of adverse health and trauma-related outcomes associated with intimate partner violence (IPV), help-seeking and service utilization among survivors is low. This study is part of a larger mixed-methods and survivor-centered validation study on the Icelandic Barriers to Help-Seeking for Trauma (BHS-TR) scale, a new barriers measure focused on trauma recovery. A mixed-methods legitimation strategy of integration was employed to evaluate the BHS-TR structure in samples of IPV survivors. The merging of qualitative (n = 17) and quantitative (n = 137) data through a joint display analysis revealed mainly complementarity findings, strengthening the scale’s overall trustworthiness and validity evidence. Divergent findings involved items about mistrust, perceived rejection, stigmatization, fearing vulnerability, and safeguarding efforts that were significant help-seeking barriers in the survivors’ narratives, whereas factor analysis indicated their removal. These BHS-TR items were critically evaluated in an iterative spiraling process that supported the barriers’ influence, illuminated core issues, and guided potential refinements. This work contributes to the growing field of mixed methods instrument validation placing equal status on qualitative and quantitative methods and emphasizing integration to provide more complete insights. Moreover, the study’s findings highlight the added value of further exploring divergence between two sets of data and the importance of giving attention to the voices of the target population throughout the validation process.

Efficacy of an online-group intervention after suicide bereavement: A randomized controlled trial

IntroductionPeople bereaved by suicide are at high-risk for developing mental disorders and suicidal tendencies. Grief after suicide differs from grief after other types of death, and bereaved persons may require support tailored to their situation. In this study, we evaluate an online intervention for individuals bereaved by suicide and its effectiveness on mental health. MethodsA total of 140 participants were included in the intervention and randomized to either the treatment or the waitlist control group. The intervention consisted of 12 weekly modules, based on cognitive-behavioral methods, and took place as a webinar in a group format. Primary outcomes were depression and suicidality; secondary outcomes were symptoms of prolonged grief, PTSD, posttraumatic cognitions, hopelessness, and grief-specific symptoms. ResultsSymptoms of posttraumatic avoidance improved significantly in the intention-to-treat analyses (dbetween = 0.43) and in treatment completers (dbetween = 0.56), posttraumatic intrusion improved in treatment completers (dbetween = 0.50) compared to the waitlist control group. In the intervention group, psychopathological symptoms decreased significantly from baseline to 6-month follow-up. Furthermore, factors such as higher scores of depression, grief, suicide ideation, and posttraumatic stress symptoms were identified at baseline, which impacted the effectiveness of the intervention. ConclusionsThe results of this study indicate that completing an online group intervention for the suicide bereaved could reduce trauma-related outcomes. However, the waiting control group also improved significantly from pre- to post-measurement in all other outcomes. Future studies with active control groups are needed to further examine the effectiveness.

Classification of posttraumatic stress disorder and related outcomes in women veterans using magnetoencephalography.

Women veterans represent a unique population whose experiences and neurobiology differ from that of their male counterparts. Thus, while previous research has demonstrated the utility of synchronous neural interactions (SNI) as a biomarker of posttraumatic stress disorder (PTSD) in male veterans, the utility of SNI as a biomarker of PTSD in women veterans is unclear. Here we extend that line of research to evaluate classification of women veterans with and without PTSD and other trauma-related outcomes based on functional connectivity using magnetoencephalography (MEG). A total of 121 U.S. women veterans completed diagnostic interviews and underwent a task-free MEG scan from which SNI was computed. Linear discriminant analysis was used to classify PTSD and control groups according to SNI. That discriminant function was then used to classify each individual in the partial recovery and full recovery diagnostic groups as PTSD or control. All individuals were classified correctly (100% accuracy) according to their SNI in their PTSD and control groups. Seventy-seven percent of the full recovery group and 69% of the partial recovery group were classified as control. Individual staging in PTSD recovery was captured by the Mahalanobis D2 distances from the center of the control and PTSD centroid clusters. These findings provide compelling evidence supporting the utility of task-free SNI as a biomarker of PTSD and related outcomes in women veterans.
