The Mediating Effect of Acceptance in the Relationship Between Resilience and Post-traumatic Stress Disorder Symptoms in Firefighters

The Somali Distress and Resilience Scale: Development of a novel measure for Somali adults.

Although resilience has been identified as an important mediator of negative mental health outcomes among refugee populations, there are few culturally specific measures of resilience among such communities and no such measure among Somalis. In this study we aimed to develop a culturally appropriate measure of resilience specific to Somali adults in San Diego, as an example of a vulnerable refugee community. A community-based, exploratory sequential mixed method investigation was conducted via focus group discussions (n = 4), cognitive interviews (n = 4), and iterative survey adaptation. Somali refugee adults in San Diego (N = 183) were surveyed with this novel scale, a standardized measure of resilience, and assessments of depression, anxiety, and PTSD. Results were analyzed via correlation coefficients and multivariate linear regression modeling. Qualitative findings supported the inclusion of items addressing both barriers and facilitators of good mental health, which resulted in the development of the Somali Distress and Resilience Survey (SDRS). Linear regression analysis revealed that the SDRS demonstrated significant associations with symptoms of depression and PTSD, while the standardized measure of resilience did not demonstrate associations with any of the mental health outcomes assessed. The SDRS identified obstacles to resilience among Somali individuals, placing them at risk of developing negative mental health outcomes. Our novel measure also demonstrated more robust relationships with these outcomes than a standardized measure of resilience, suggesting greater utility of the adapted scale. However, the SDRS's development raises larger questions about the limitations of developing and comprehensively evaluating novel resilience measures in a community-based setting.

Heart Rate Variability Biofeedback as a Treatment for Military PTSD: A Meta-Analysis.

Emerging research has provided tentative support for the use of heart rate variability biofeedback (HRVB) as a treatment for several psychological disorders, with meta-analyses providing compelling evidence for HRVB as a promising treatment for anxiety, depression, and PTSD. Given the prevalence of PTSD in military veterans and the comparatively lower benefit and higher attrition rate of traditional psychological treatment for PTSD relative to civilian counterparts, it is important to examine complementary and alternative treatment approaches such as HRVB in this population. Although studies of HRVB for PTSD have been conducted with military veterans, they have involved relatively small sample sizes, limiting interpretation. To address this, the current article presents a comprehensive meta-analysis, consolidating existing literature to more accurately evaluate the efficacy of HRVB in reducing PTSD symptoms within military populations. This meta-analysis was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, and our protocol was registered with PROSPERO to increase review transparency. A literature search of HRVB interventions was conducted using PubMed, PsycINFO, Military Database, PTSDPubs, and EBSCO's Psychological and Behavioral Sciences Collection. Five studies met eligibility criteria, providing a combined sample size of 95 military services members. For all studies, effect sizes were negative, indicating a reduction in PTSD symptoms. Effect sizes ranged from -1.614 to -0.414, resulting in an overall moderate to large mean effect for HRVB (Hedges's g = -0.557; 95% confidence interval = -0.818 to -0.296; P < .001). Additionally, cumulative attrition was 5.8%, significantly lower than commonly reported rates for evidence-based treatments (16%-36%). The present study is the first meta-analysis to examine HRVB as a treatment for military service members with PTSD. Results indicate that HRVB may be a viable treatment approach to reduce PTSD symptomatology. Low attrition rates, ease of accessibility, and favorable participant outlook serve as additional benefits for the use of HRVB.

DSM-5 BPD and ICD-11 complex PTSD: Co-occurrence and associated factors among treatment seekers in Hong Kong

There is an ongoing debate regarding whether ICD-11 complex PTSD and DSM-5 borderline personality disorder (BPD) are the same syndrome. Little is known about the extent to which these two conditions overlap and whether they exhibit distinct clinical correlates in Asian cultures. This study examined the co-occurrence of ICD-11 complex PTSD and DSM-5 BPD in a sample of treatment seekers in Hong Kong (N = 220). Participants completed validated self-report measures which assessed if they met the respective diagnostic criteria. In this sample, 30.9 % met the ICD-11 criteria for complex PTSD only, 10.0 % met the DSM-5 criteria for BPD only, and 28.2 % met the criteria for both conditions. Complex PTSD symptoms were most strongly associated with depressive symptoms (β =.347, p <.001) and trauma-related maladaptive beliefs (β =.337, p <.001), while BPD symptoms were most strongly associated with dissociative symptoms (β =.281, p <.001). This study is the first to show that ICD-11 complex PTSD and DSM-5 BPD commonly co-occurred but were not the same construct in the Asian context, and their symptoms were associated with different sets of demographic and clinical factors. Future editions of DSM and ICD should not merge the two conditions into a single diagnosis.

The contribution of maladaptive personality traits to PTSD and depression symptoms among Israeli female veterans.

Exposure to potentially traumatic events during military service is associated with mental health problems such as posttraumatic stress disorder (PTSD) and depression symptoms. However, knowledge regarding the implications of maladaptive personality traits in psychopathology among female veterans is sparse. The present study aims to use the Diagnostic and Statistical Manual of Mental Disorders, fifth edition-an alternative model of personality disorder, to examine associations between maladaptive personality traits, PTSD and depression symptoms, among female Israeli veterans. A volunteer sample of female Israeli combat veterans (n = 616) and noncombat veterans (n = 484) responded to self-report questionnaires in a cross-sectional study. Combat veterans reported higher levels of combat exposure and PTSD symptoms, but not depressive symptoms, than noncombat veterans. Combat veterans also reported lower levels of negative affectivity but higher levels of disinhibition than noncombat veterans. All five traits were positive predictors of PTSD and depression symptoms, with psychoticism constituting the strongest predictor. A moderated-mediation analysis indicated four traits (negative affectivity, detachment, disinhibition, and psychoticism) that had a moderating effect on the relationship between combat exposure and PTSD symptoms, and two of the traits (antagonism and disinhibition) that had a moderate effect on the relationship between combat exposure and depressive symptoms. Maladaptive personality traits play an important role in psychological distress following female veterans' combat service. Future prospective research is necessary to determine the temporal associations between preenlistment maladaptive personality traits and postdeployment mental health of veterans.

The relationship between specific auditory hallucinations and acute PTSD vs. complex PTSD following direct and indirect exposure to the October 7 events in Israel

This preliminary study examines the link between war-related auditory (pseudo)hallucinations and symptoms of acute ICD-11 posttraumatic stress disorder (PTSD) and Complex PTSD (CPTSD) amidst ongoing conflict, with a specific focus on CPTSD. The research, which analyzed data from 2028 Israeli residents following the traumatic events of October 7, 2023, investigated the perception of non-existent sirens and their association with acute PTSD and CPTSD symptoms. The findings reveal that (pseudo)hallucinations were more prevalent among individuals with acute CPTSD symptoms compared to those with PTSD symptoms alone. Additionally, auditory (pseudo)hallucinations were significantly associated with a higher likelihood of CPTSD versus PTSD. These results were consistent for those directly and indirectly exposed individuals to the October 7 attack. Despite its cross-sectional nature, the study provides valuable insights into trauma-related auditory (pseudo)hallucinations in wartime contexts.

Internalized stigma and traumatizing effects of psychiatric hospitalization in adolescents: Is there any difference between being hospitalized in adult or adolescent inpatient psychiatric services?

Psychiatric hospitalization serves as a critical treatment modality. However, hospitalization may pose risks of traumatization or stigma. This study primarily examined the internalized stigma and traumatizing effects of psychiatric hospitalization on adolescents. Additionally, the treatment of adolescents within adult inpatient psychiatric services may yield differing stigmatization and posttraumatic stress disorder (PTSD) symptomatology. Hence, the secondary objective was to discern the variance in stigmatization and PTSD symptoms between adolescents treated in adult inpatient psychiatric services (AIPS) and those in child and adolescent inpatient psychiatric services (CAIPS). The cohort consisted of patients from Akdeniz University's Adult Psychiatry Inpatient Service (n = 29) and Uludağ University's Child and Adolescent Psychiatry Inpatient Service (n = 28), matched for age and gender. Assessments using the Child Posttraumatic Stress Disorder-Reaction Index and the Internalized Stigma Scale for Children and Adolescents (ISSCA) were conducted 6 months after discharge. 36.8% and 10.5% of adolescents exhibited "mild" and "very severe" PTSD symptoms, respectively. Adolescents treated in CAIPS had higher Child Posttraumatic Stress Disorder-Reaction Index scores than those in AIPS. However, there was no significant difference between the AIPS and CAIPS groups regarding ISSCA-self and ISSCA-perceived scores. The current findings underscore that psychiatric hospitalization can lead to traumatic experiences in adolescents, especially those treated in CAIPS. Providing informed care and emotional support during hospitalization could bolster resilience and facilitate recovery among these individuals. While adolescents are sometimes placed in AIPS, it is crucial that professionals are adequately trained and supported in managing this vulnerable population.

Behavioral economic analysis of the comorbidity of alcohol problems and posttraumatic stress: Findings from high-risk young adults and general community adults.

A behavioral economic reinforcer pathology model theorizes that alcohol problems are influenced by steep delay discounting, overvaluation of alcohol reinforcement, and low reinforcement from alcohol-free activities. Extending this account to the comorbidity of alcohol problems and posttraumatic stress disorder (PTSD), the present study tested the hypothesis that alcohol problems and PTSD symptom severity would interact and be positively associated with indicators from these three domains. High-risk emerging adults from North America (Study 1, n = 1,311, Mage = 22.13) and general community adults from Canada (Study 2, n = 1,506, Mage = 36.80) completed measures of alcohol problems, PTSD symptoms, delay discounting, alcohol demand, and proportionate alcohol-related reinforcement. Across studies, regression analyses revealed significant main effects of alcohol problems and PTSD symptoms in relation to selected reinforcer pathology indicators, but no significant interactions were present for delay discounting or proportionate alcohol-related reinforcement. Interactions were observed for alcohol consumption at $0 (intensity) and the rate of change in consumption across the demand curve (elasticity; Study 1) and for elasticity and maximum alcohol expenditure (Omax; Study 2), but not in the predicted directions. Higher synergistic severity was associated with lower alcohol reinforcing value in each case. These findings reveal expected relations between reinforcer pathology indicators and both alcohol problems and PTSD symptomatology in general but did not support the hypothesized synergistic relationship. The relation between alcohol problems and PTSD is more complex than predicted by existing extensions of the reinforcer pathology model, warranting further investigation.

Prolonged exposure for posttraumatic stress disorder following spinal cord injury: A randomized controlled trial.

Individuals with a spinal cord injury (SCI) may experience posttraumatic stress disorder (PTSD) at a higher rate, which is associated with worse psychiatric comorbidity, decreased quality of life, and greater disability. Yet, effective PTSD interventions remain understudied for individuals with SCI. We conducted the first randomized controlled trial (RCT) of an evidence-based psychotherapy (prolonged exposure [PE]) with survivors of SCI during acute rehabilitation. We examined the efficacy, feasibility, and secondary outcomes. Participants (n = 29) were adults recruited from 2018 to 2021 1-month postinjury with PTSD randomized into either PE therapy or treatment as usual. The primary outcome was PTSD assessed at baseline, 6, 10, and 32 weeks postenrollment. An overall group-by-time interaction was not statistically significant (p = .102), but effect sizes demonstrated moderate and large improvements in PTSD for the PE group at 6 (-19.4 vs. -9.7) and 10 (-25.8 vs. -5.7), respectively. Similarly, moderate to large effect sizes were observed for depression, maladaptive posttraumatic cognitions, disruptive nocturnal behaviors, SCI-related quality of life, and risky alcohol consumption. Low rates of enrollment (50%) and treatment completion (25%) suggest feasibility challenges; however, treatment completers did report high satisfaction (100%). Results suggest that individuals who received PE had a quicker and clinically meaningful reduction in PTSD symptoms, but delivery during acute rehabilitation is not feasible for many individuals. Future research should examine abbreviated versions of PE for PTSD to enhance the feasibility of treatment in this setting. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Negative global metacognitive biases are associated with depressive and posttraumatic stress disorder symptoms and improve with targeted or game-based cognitive training.

Metacognition is disrupted in several clinical populations. One aspect of metacognition, global metacognitive bias (difference between objective and self-reported abilities), has shown to be particularly relevant to clinical functioning. However, previous studies of global metacognitive biases in populations with elevated depressive/posttraumatic stress disorder (PTSD) symptoms have not measured objective and self-reported abilities relative to normative samples, limiting the quantification of biases. Additionally, few studies have examined whether cognitive interventions can improve metacognitive biases or how this relates to depressive/PTSD symptom severity. A total of 84 participants with mild traumatic brain injury (77% veterans) performed PTSD and depression assessments along with self-reported and objective measures of global cognition. Age-adjusted norm-based z scores were used for self-reported and objective cognition, and bias was calculated by subtracting objective minus self-report scores. Participants then received 13 weeks of targeted cognitive training or entertainment games training (both providing performance feedback). Participants were assessed at baseline, immediately posttraining, and 3 months posttraining. We found large negative metacognitive biases in those with clinically significant severity of depressive symptoms (z score difference = -1.77), PTSD symptoms (-1.47), and depressive + PTSD symptoms (-2.29). Metacognitive biases improved after both targeted and entertainment training and was associated with reductions in depressive/PTSD symptom severity (r = -.41/-.42, respectively), led by the entertainment training group (r = -.54/-.46, respectively). These findings show that clinically significant severity of depressive/PTSD symptoms is associated with substantial negative global metacognitive biases and preliminarily suggests that cognitive training may improve these biases and depressive/PTSD symptom severity.

The mediated model of PTSD between ADHD symptoms and alcohol abuse in a population of college students in Taiwan

PurposeImpulsivity, inattention, childhood trauma, PTSD, and depressive symptoms were the high-risk factors of alcohol abuse in ADHD symptoms. There is a lack of a comprehensive framework of trauma and PTSD in ADHD symptoms with alcohol abuse to explain why ADHD college students become problematic alcohol drinking. Method521 college students were recruited from online platforms (e.g., Facebook, LINE, or Google) after informed consent (females, 67.9%, n = 354; averaged age = 20.34, S.D. = 1.98). All of them completed the questionnaires, which included symptoms of ADHD, inattention and impulsivity, depressive symptoms, childhood trauma, PTSD symptoms, and problematic alcohol drinking. One-way ANOVA and path analysis were applied to examine the significance of eight paths. ResultsOur results supported the mediating effects of childhood trauma and PTSD symptoms in ADHD symptoms with problematic alcohol drinking. DiscussionThe effect of complex PTSD between impulsivity and problematic alcohol drinking is still unclear. In addition to impulsivity and inattention to ADHD symptoms with problematic alcohol drinking, the impact of hyperactivity also needs to be considered. ConclusionsEffective treatment for ADHD symptoms with alcohol abuse could focus on self-control training and emotional regulation in the future.

Protocol for a randomized clinical trial of strength at home parents: A trauma informed parenting intervention for veterans

BackgroundPost-traumatic stress disorder (PTSD) is highly prevalent in veterans and associated with impairments in family functioning, including parenting. There is a bidirectional relationship between PTSD and familial functioning such that impaired functioning is related to increases in trauma-related symptoms, and vice versa. Despite this known bidirectional association, there is currently no trauma-informed parenting intervention available for veterans within the Department of Veterans Affairs (VA). Strength at Home – Parents (SAHP) is an 8-session telehealth delivered psychotherapy group that aims to improve parenting behaviors and overall parent-child and family functioning among U.S. military veterans with PTSD symptoms. This paper describes the methods of an individually randomized group therapy trial to test the efficacy of SAHP compared to a VA treatment as usual control condition.Methods are reported using SPIRIT guidelines. MethodsOne hundred and ninety veterans with elevated PTSD symptoms and parent-child functioning problems will be randomly assigned to the SAHP intervention or a treatment-as-usual control group. Outcomes are measured at 4 timepoints including baseline. The primary outcome is parenting stress. We will also examine changes in parenting behaviors, whether treatment gains are maintained over time, and will conduct an exploratory analysis to examine results separately by gender. Secondary outcomes include symptoms of PTSD and depression, family functioning, and child psychosocial functioning. ConclusionStudy findings will determine the efficacy of SAHP, an intervention developed for ease of use and implementation within the VA to improve parenting stress and parenting behaviors in veterans with elevated PTSD symptoms and parenting difficulties.

Controlled Inhalation of Tetrahydrocannabinol-Predominant Cannabis Flos Mitigates Severity of Post-Traumatic Stress Disorder Symptoms and Improves Quality of Sleep and General Mood in Cannabis-Experienced UK Civilians: A Real-World, Observational Study

Introduction: Approximately 4% of the UK population experiences PTSD. Individuals must exhibit symptoms across four clusters to receive a diagnosis: intrusion, avoidance, altered reactivity, and altered mood. Evidence suggests that cannabinoid agonists such as nabilone and tetrahydrocannabinol (THC) may alleviate PTSD symptoms. We investigated the safety and effectiveness of THC-predominant cannabis flowers for inhalation to manage PTSD symptoms in a real-world setting. Methods: We analysed data from the UK patient registry, T21. Validated questionnaires were used to collect PROMs for health-related quality of life (HRQoL), mood/anxiety, sleep, and PTSD-specific symptoms. Inclusion criteria were (i) a confirmed diagnosis of PTSD, (ii) completed PROMs questionnaires at baseline and at the 3-month follow-up, and (iii) received a prescription for a chemotype 1 (THC-predominant) cannabis flower. Results: Fifty-eight patients were included, 34 of which also had PROMs recorded at 6 months. Most were males (65.5%) with an average age of 39.2 years who had previously used cannabis illicitly (95.6%). At 3 months, participants reported significant improvements in overall health, mood, and sleep quality (p < 0.001) but not in the proxy for HRQoL (p = 0.052). Similarly, participants reported substantial benefits in managing intrusion symptoms (p < 0.001), mood alterations (p < 0.001), and reactivity alterations (p = 0.002), which were sustained or further improved at 6 months. Participants did not report any side effects associated with CBMPs. Conclusions: Inhalation of THC is well tolerated and useful for managing symptoms of PTSD in cannabis-experienced individuals. However, further research is needed to evaluate the long-term safety and outcomes of controlled inhalation of CBMP in patients naïve to cannabis.

Validation of the PCL-5 in Dutch trauma-exposed adults

BackgroundThe PTSD Checklist for DSM-5 (PCL-5) is an internationally widely used self-report questionnaire that can be used to screen for probable diagnosis of posttraumatic stress disorder (PTSD). Information on the psychometric properties of the Dutch PCL-5 is currently lacking.ObjectiveWe aimed to validate the Dutch PCL-5 in a sample of Dutch adults with prior (suspected) serious injury and establish the optimal cut-off for probable PTSD diagnosis herein.MethodsData for the current study were collected as part of a long-term follow-up measurement of the TraumaTIPS cohort, where adults admitted to an emergency department following (suspected) serious injury completed a follow-up measurement 12–15 years post-trauma. Of N = 333 eligible participants, n = 192 (57.7%) consented and completed the PCL-5 alongside self-report instruments measuring depression (QIDS), PTSD (IES-R), and quality of life (WHO-QOL and EQ-6D). In total, n = 185 participants also completed a clinician administered interview for PTSD (CAPS-5). Most participants were men (66%) and on average 54 years old (SD = 12.41). We evaluated the diagnostic utility of the PCL-5 using Youden index and tested reliability and convergent validity.ResultsThe PCL-5 demonstrated excellent diagnostic accuracy with a cut-off point of 16 resulting in an optimal Youden index (0.90) for screening purposes with a high sensitivity (1.00) and specificity (0.90). A cut-off of 22 yielded a slightly lower Youden index (0.84) but better positive predictive value (0.50 instead of 0.33) than the cut-off of 16. A cut-off of 29 resulted in the most accurate prevalence estimates. The PCL-5 showed a high internal consistency (Cronbach’s α = 0.94), excellent inter-item and item-total correlations and good convergent validity (r > .5 for CAPS-5, IES-R and QIDS).ConclusionsThe PCL-5 is a reliable and valid measurement for PTSD symptoms and probable diagnosis and shows excellent screening abilities in Dutch adults with prior (suspected) serious injury, with a lower optimal cut-off compared to previously found in clinical populations. We recommend a cut-off of 22 for screening purposes and a cut-off of 29 for prevalence estimates in Dutch trauma-exposed adults.

Sleep disorder symptoms and suicidal urges among US Marines seeking suicide treatment: Findings from an intensive daily assessment study

BackgroundRates of suicide in United States Marines are among the highest in the military, and sleep disorder symptoms are a known risk factor for suicide in the military. Intensive ecological momentary assessments (EMA) might improve the ability to detect periods that are characterized by increased suicidal ideation. Marines who were at high risk for suicide were intensively assessed for one month on sleep, suicidal urges, posttraumatic stress disorder (PTSD) and depression symptoms. MethodsU.S. Marines (N = 40) who had a past month suicide attempt or suicidal urges with intent were sent EMA for 28 days. Mixed effects models explored associations among daily sleep, suicidal urges, PTSD, and depression symptoms. ResultsWorsened sleep indicators on a given night significantly predicted higher maximum values of suicide urges the following day. Worse sleep quality the prior night was moderately associated with more severe PTSD symptoms and depression symptoms. Greater severity of PTSD symptoms and depression symptoms were strongly associated with both the maximum value and the range of suicide urges. PTSD and depression symptoms mediated the relationship between sleep quality and suicidal urges. Participants reported that 0000–0300 had the greatest elevation in endorsement of highest suicide urges. LimitationsThis study had a small sample size may not generalize beyond active duty Marines. ConclusionsPoor sleep quality and other sleep markers were an important risk factor for suicidal urges among U.S. Marines. This relationship was mediated by exacerbations in PTSD and depression symptoms. Interventions are needed to interrupt suicide risk during and following nights with poor sleep.

One-year predictors of PTSD symptoms, anxiety, and depression in SARS-CoV-2 survivors: psychological flexibility and major life events as main predictive factors.

The COVID-19 pandemic held considerable health-related outcomes worldwide, including mental health challenges, with elevated risk of psychiatric sequelae. This study aimed to test the longitudinal (1 year) predictive role of psychosocial factors on post-traumatic stress disorder (PTSD), anxiety, and depressive symptoms in SARS-CoV-2 survivors (N = 209 at T1; N = 61; attrition rate 70.83%), through Pearson's correlation analyses and longitudinal multiple regression analyses. Participants (age M = 35.4, SD = 10.1) completed online self-report questionnaires of psychosocial variables, PTSD, anxiety, and depression. Depression and anxiety symptoms were increased, and 42% of survivors presented clinically meaningful PTSD symptoms. PTSD symptoms were longitudinally predicted by having children (β = 0.32, p < 0.01), number of recent major life events (β = 0.34, p < 0.01), and psychological flexibility (β = -0.36, p < 0.01). Number of major life events (β = 0.29, p < 0.05) and psychological flexibility (β = -0.29, p < 0.05) predicted anxiety. Number of recent major life events (β = 0.32, p < 0.01) was the sole predictor of depressive symptoms. Psychosocial variables contribute to the long-term harmful effects of the COVID-19 pandemic on psychopathological symptoms. These results suggest that, during the pandemic, mental health was impacted by both socio-contextual factors and individual self-regulatory skills, namely the ability to respond flexibily to contextual cues and guide behavior according to the direct experience. Specifically, results point out the importance of societal incentives to reduce parental burden and socioeconomic losses, as well as to promote adaptive psychological skills such as psychological flexibility.

(Complex) PTSD in Ukrainian refugees: Prevalence and association with acts of war in the Danish refugee cohort (DARECO)

BackgroundThe Russian invasion of Ukraine has driven millions of Ukrainians away from their homes. Among these, the majority have likely experienced war-related potentially traumatic events, and some will experience symptoms of posttraumatic stress disorder (PTSD). The aims of the study are to estimate the prevalence of PTSD and Complex PTSD (CPTSD) in displaced Ukrainians and examine associations between war- and other potentially traumatic exposures and (C)PTSD. MethodsQuestionnaires were distributed to all registered adult Ukrainians (18+) who arrived in Denmark between February 24th 2022 and February 15th 2023 (N = 18,389). We estimate the prevalence of war exposures, other potentially traumatic exposures, and (C)PTSD. In logistic regression analyses, we test if exposure to war and other potentially traumatic events are associated with PTSD and CPTSD. ResultsThe final sample size was 6993 (38.0 %). Responders were more likely to be female and younger than non-responders. Prevalence of PTSD and CPTSD was 15.9 % and 13.5 %, respectively. Female gender, high education, and loss of a relative due to the war were associated with (C)PTSD. Direct and indirect exposure to war and combat was related to PTSD but not CPTSD, while exposure to war prior to the 2022 invasion was related to CPTSD but not PTSD. LimitationsThe study is cross-sectional and based on self-report. ConclusionClose to one third of the sample fulfill the criteria of PTSD or CPTSD. War exposures are differentially related to PTSD and CPTSD. The findings illustrate that trauma-related psychopathology is a pertinent problem in displaced Ukrainians.

Trauma focused-cognitive behavioral therapy training effectiveness in promoting professional development of psychotherapists working with unaccompanied minors in Greece: a non-blinded randomized control trial.

The need to develop psychotherapists' skills to respond to current treatment challenges, such as addressing trauma due to the refugee crisis, is increasing. However, there is a dearth of evidencebased training for psychotherapists who work with refugees, especially in frontline countries. A randomly selected sample of 80 clinicians working with unaccompanied minors (UAMs) in Greek accommodation centers nationwide participated in an intensive trauma-focused cognitive behavioral therapy (TF-CBT) training (n=44) or a control-group (n=36) and completed the Professional Quality of Life Scale, the Work and Meaning Inventory and a questionnaire to assess knowledge and therapeutic skills, in pre-andpost measurements. Clinicians with 1-3 years of experience with refugees reported higher burnout (p=0.012, M=25.78 vs M=22.04) and secondary traumatic stress than those with less than a year (p=0.014, M=22.03 vs M=18.04). Positive meaning at work increased in both groups at post-test (TF-CBT group: p=0.019, M=15 vs M=13.6, and control group: p<0.001, M=15.17 vs M=13.42). The TF-CBT training group outperformed the control group in knowledge and skills (p=0.021, M=10.15 vs M=8.75) and identified a lower number of children with post-traumatic stress disorder symptoms (p=0.009, M=6.94 vs M=4.33) post-training. This study provides preliminary evidence on TF-CBT training effectiveness in equipping psychotherapists to work with UAMs, while their professional quality of life warrants further research.

Developing and testing a community based, online vs. face-to-face peer led intervention to improve mental well-being in Cambodian adults with physical disabilities.

Despite growing international attention, there remains an urgent need to develop mental health services within low and middle income countries. The Khmer Rouge period in Cambodia saw the destruction of all health services infrastructure in the 1970s. Consequently, Cambodia has struggled to rebuild both its economy and healthcare system, with the number of qualified mental health clinicians remaining disproportionately low. Resultantly, there is a pressing need to develop low-cost community based alternatives of mental healthcare. Using a mixed methods design, researchers developed an 8-week peer-led intervention, known as a Friendship Group, for adults with physical disabilities using both face-to-face and online delivery methods. The Wilcoxon Signed-Rank test was used to assess changes in pre-post survey scores and qualitative data was collected in form of five focus groups post intervention. 41 participants were allocated across four Friendship groups - two were online and two face-to-face. Attrition rate was 22% post-intervention (n = 32). ITT analyses showed a statistically significant decrease in psychological distress scores [Z = -3.808, p < .001] from pre [Mdn = 20, IQR = 16.5-25.5] to post [Mdn = 16, IQR = 14-18.5] intervention. A Wilcoxon signed-ranks test also showed a statistically significant decrease in PTSD scores [Z = -2.239, p < .025] from pre [Mdn = 4, IQR = 3-5] to post [Mdn = 3, IQR = 2.75-4] intervention. There was also a statistically significant decrease in worry scores [Z = -3.904, p < .001] from pre [Mdn = 5, IQR = 3.5-6.5] to post [Mdn = 3, IQR = 3-4] intervention. There were no significant group differences between the face to face and online groups. A number of interconnected themes emerged from focus group data (n = 5), these included the mental health benefits of Friendship Groups as conceptualised through knowledge acquisition, skill development and peer support. The Friendship group intervention delivered in both online and face-to-face formats appears feasible and acceptable within the Cambodian context. Initial data revealed positive findings in terms of reduction in psychological distress, worry and PTSD symptoms as well increased feeling as calm.

Clinical benefits of self-guided mindfulness coach mobile app use for veterans with posttraumatic stress disorder: A pilot randomized control trial.

Mindfulness training can relieve posttraumatic stress disorder (PTSD) symptoms in military veterans and others but is inconsistently accessible. Self-guided mobile apps could improve access but their acceptability, feasibility, and benefits for veterans with PTSD have not been established. We conducted a pilot randomized trial of Mindfulness Coach (MC), a free, publicly available, trauma-informed mobile app tailored to veterans. U.S. veterans with PTSD (n = 173) were randomized to self-guided use of MC or waitlist control (WLC) with 8-week follow-up. Clinical outcomes were PTSD symptoms (PTSD Symptom Checklist-5), depression symptoms (Patient Health Questionnaire, nine item), and psychosocial functioning (Brief Inventory of Psychosocial Functioning). Primary analyses were intent-to-treat using linear mixed models with maximum likelihood estimation. App uptake, objective usage, and usability ratings measured acceptance and feasibility. Participants varied in age, gender, and ethnoracial identity; most reported recent mental health care utilization. Although study attrition was high (68.4% overall) due to participant dropout (treatment: 43.0%; control: 43.7%) and technical study issues (23% overall), diagnostic tests showed no evidence of bias due to missingness. Study completers (MC: n = 19; WLC: n = 37) showed medium effects on PTSD symptoms (b = -9.31, d = -0.69) and depression (b = -3.10, d = -0.52). Higher-intensity users showed greater benefits. App engagement trended lower for women and minoritized subpopulations. No changes were observed in psychosocial functioning. Usability and helpfulness ratings were favorable. Transdiagnostic clinical benefits indicate promise for MC as a public health resource for veterans with PTSD. Further study is warranted to confirm these benefits and ensure consistent engagement across subpopulations. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
