ABSTRACT

Although the association between post-traumatic stress disorder (PTSD) and social support is well documented, few studies have tested the causal pathways explaining this association at several points in the acute post-trauma recovery period or examined whether the association varies for different sources of social support. To address these gaps, 151 community individuals (mean age = 37.20 years, 69.5% women) exposed to trauma within the previous 6 months were recruited to complete measures of PTSD and social support from intimate partners, friends, and relatives four times in 1 year. In line with recent recommendations for research on social support and PTSD symptoms, random intercept cross-lagged panel modeling (RI-CLPM) was used to examine dynamic changes between PTSD severity and social support over time. The pattern of RI-CLPM cross-lagged coefficients indicated that positive deviations from one's expected stable level of total social support (across all sources) sped up the recovery of PTSD symptoms at the end of the post-trauma year, and more severe PTSD symptoms than expected based on one's expected stable level of PTSD started eroding social support midway through the assessment year. When specific sources of social support were analyzed separately, the association between within-person increases in social support from friends at any given time point accelerated the recovery from PTSD across the entire year. Among participants with intimate partners (n = 53), intimate partner support did not predict PTSD symptoms, but more severe PTSD symptoms at any given time point predicted less support at the following time point. Results from this longitudinal study provide additional support for the bidirectional relationship between PTSD and social support over time and suggest that perceived social support from friends may be especially helpful during trauma recovery.

ABSTRACT

Objective: Suicidal ideation (SI) is highly prevalent among college students. Research has shown that college students are also more likely to experience low distress tolerance, affect lability, and experiential avoidance, which have been linked to SI. There is a critical need to examine the mechanisms that increase the risk of SI among college students. It is hypothesized that distress tolerance will be a strong predictor of SI, and affect lability as well as experiential avoidance will mediate this relationship. Participants and Methods: Participants (n = 820) from a Southeastern University completed an online survey, inquiring about demographic information, affect lability, SI, experiential avoidance, and distress tolerance. Data were analyzed utilizing structural equation modeling. Results: Distress tolerance was not directly related to SI. However, affect lability and experiential avoidance were found to mediate this relationship. Conclusions: Affect lability and experiential avoidance may be important predictors of SI among college students.

ABSTRACT

OBJECTIVE: Veterans seeking treatment for posttraumatic stress disorder (PTSD) commonly report general and veteran-specific barriers to treatment such as stigma and challenges with navigating the Veterans Health Affairs (VHA) system. This study aimed to characterize barriers endorsed by a national sample of veterans seeking care in VHA PTSD specialty outpatient clinics, as well as to examine the impact of demographics on endorsed barriers. METHODS: This study included 17,069 veterans referred to PTSD specialty outpatient clinics in the VHA during Fiscal Year 2019. Barriers to care, demographics, clinical concerns, and PTSD symptom severity (PCL-5) were assessed at intake. RESULTS: Veterans (mean age=47.6 years, 83.3% male) endorsed an average of 2.39 barriers. The most commonly endorsed barriers included difficulty interacting with others (37.9%), difficulty being in public (33.8%), work (30.3%), concern for finances (20%), and difficulty getting out of bed (19.5%). A significant minority of veterans (22%) endorsed no barriers. Male sex (23.1%) and White race (23.6%) were associated with a greater likelihood of reporting no barriers. CONCLUSIONS: These findings indicate the need for a comprehensive approach to addressing multi-faceted barriers for veterans seeking treatment in PTSD specialty clinics. Findings also highlight the potential importance of tailoring strategies to reduce barriers based on demographic and clinical characteristics such as race, sex, and degree of avoidance. Future research should seek to longitudinally examine the impact of barriers on treatment engagement.

ABSTRACT

Interpersonal functioning is a common concern for people with postttraumatic stress disorder (PTSD) but is not a key target of most trauma-focused psychotherapies (TFPs). We preregistered and undertook a systematic review and meta-analysis of randomized clinical trials (RCTs) examining the efficacy of TFPs for improving interpersonal functioning. Studies were identified through the PTSD Trials Standardized Data Repository, scholarly databases, and the solicitation of unpublished data from the PTSD research community following current PRISMA guidelines. We used random effects meta-analysis to estimate within-group change (i.e., pre- to posttreatment) in interpersonal functioning. Meta-analytic findings yielded a medium total effect of TFP on interpersonal functioning, g = 0.54, 95% CI [0.37, 0.72], with high between-study heterogeneity. Sensitivity analyses yielded substantively equivalent point estimates when outliers were excluded, g = 0.55, and when only the most well-established individual TFPs were included, g = 0.57. In contrast, allocation to a control condition was associated with little average change in interpersonal functioning, g = 0.04 [-0.12, 0.21]. Formal tests did not yield clear evidence of publication bias. Bias-corrected estimates varied but centered around a medium effect, gs = 0.41-1.11. There was a medium-to-large association between change in interpersonal functioning and change in PTSD symptoms, rs = -.35--.44. The extant literature on TFPs and interpersonal functioning is small and heterogeneous, indicating the need for more focused attention on this outcome. Results suggest that, on average, TFPs are moderately efficacious for improving interpersonal functioning; however, additional treatment may be needed to meet the desired level of improvement.

ABSTRACT

OBJECTIVE: Implementation of evidence-based suicide prevention is critical to prevent death by suicide. Contrary to previously held beliefs, interventions including contracting for safety, no-harm contracts, and no-suicide contracts are not best practices and are considered contraindicated. Little is known about the current use of best practices and contraindicated interventions for suicide prevention in community settings. METHODS: Data were collected from 771 individuals enrolled in a suicide prevention training. Both mental health clinicians (n = 613) and mental health allies (e.g., teachers, first responders) (n = 158) reported which best practices (i.e., safety plan, crisis response plan) and contraindicated interventions (i.e., contracting for safety, no-harm contract, no-suicide contract) they use with individuals who presents with risk for suicide. RESULTS: The majority of both mental health clinicians (89.7%) and mental health allies (67.1%) endorsed using at least one evidence-based practice. However, of those who endorsed using evidence-based interventions, ∼40% of both mental health clinicians and allies endorsed using contraindicated interventions as well. CONCLUSION: Contraindicated interventions are being used at high rates and suicide prevention trainings for evidence-based interventions should include a focus on de-implementation of contraindicated interventions. This study examined only a snapshot of what clinicians and allies endorsed using. Additional in depth information about each intervention and when it is used would provide helpful information and should be considered in future studies. Future research is needed to ensure only evidence-based interventions are being used to help prevent death by suicide.Highlights:The majority of both mental health clinicians and mental health allies use evidence-based practices for suicide prevention. This indicates good implementation rates of evidence-based interventions for suicide prevention.Approximately 40% of both mental health clinicians and mental health allies who endorsed using evidence-based practices for suicide preventions also endorsed using contraindicated interventions.A focus on de-implementation of contraindicated suicide interventions is warranted and should be part of the focus on suicide prevention efforts.

ABSTRACT

Preliminary data suggest cognitive processing therapy (CPT) significantly reduces posttraumatic stress disorder (PTSD) symptom severity among military personnel and veterans when delivered over 12 days and combined with daily recreational activities (Bryan et al., 2018). The present study aimed to examine how therapy pace (i.e., daily vs. weekly sessions) and setting (i.e., clinic vs. recreational) impacts change in PTSD symptom severity. Forty-five military personnel and veterans diagnosed with PTSD chose to receive CPT (a) daily at a recreational facility with recreational programming, (b) daily on a university campus without recreational programming, and (c) weekly on a university campus without recreational programming. PTSD symptom severity was assessed with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) and the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5). Reductions in CAPS-5 and PCL-5 scores were large and statistically significant across all three settings (Cohen's ds > 2.1). As compared to reductions in CAPS-5 and PCL-5 scores in daily therapy at a recreational facility (CAPS-5: d = 1.63-2.40; PCL-5: d = 1.99-2.17), reductions in CAPS-5 and PCL-5 scores were significantly larger in daily therapy on campus, CAPS-5: t(80) = -2.9, p = .005, d = 2.23-2.69; PCL-5: t(78) = 2.6, p = .010, d = 2.54-4.43, but not weekly therapy on campus, CAPS-5: t(80) = 0.2, p = .883, d = 1.04-2.47; PCL-5: t(78) = 1.0, p = .310, d = 1.77-3.44. Participants receiving daily therapy on campus and weekly therapy on campus also had higher rates of clinically significant improvement and good end-state functioning. Results support the effectiveness of CPT across multiple treatment settings and formats and suggest that daily CPT may be less effective when delivered in combination with recreational activities.

ABSTRACT

Posttraumatic stress disorder (PTSD) is a significant mental health issue among military service members and veterans. Although the U.S. Department of Veterans Affairs (VA) provides crucial resources for behavioral health care, many veterans seek mental health services through community clinics. Previous research illustrates that military and veteran patients benefit less from evidence-based treatments (EBTs) for PTSD than civilians. However, most PTSD treatment outcome research on military and veteran populations is conducted in VA or military settings. Little is known about outcomes among military-affiliated patients in community settings. The primary aim of this study was to directly compare civilian versus military-affiliated patient outcomes on PTSD and depression symptoms using the PTSD Checklist for DSM-5 (PCL-5) and the nine-item Patient Health Questionnaire (PHQ-9) in a community setting. Participants (N = 502) included military-affiliated (veteran, Guard/Reservist, active duty) and civilian patients who engaged in cognitive processing therapy (CPT) or prolonged exposure (PE) for PTSD in community clinics. Both groups demonstrated significant reductions on the PCL-5, military-affiliated: d = -0.91, civilian: d = -1.18; and PHQ-9, military-affiliated: d = -0.65, civilian: d = -0.88, following treatment. However, military-affiliated patients demonstrated smaller posttreatment reductions on the PCL-5, Mdiff = 5.75, p = .003, and PHQ-9, Mdiff = 1.71, p = .011, compared to civilians. Results demonstrate that military-affiliated patients benefit from EBTs for PTSD, albeit to a lesser degree than civilians, even in community settings. These findings also highlight the importance of future research on improving EBTs for military personnel with PTSD.

ABSTRACT

Posttraumatic stress disorder (PTSD) is a well-established risk factor for suicidal thoughts and behaviors. Historically, guidelines for treating PTSD have recommended against the use of trauma-focused therapies for patients who are at high risk for suicide, likely due to concerns about potential suicide-related iatrogenesis, specifically the "triggering" of suicidal behaviors. This systematic review examined evidence of the impact of treatments specifically designed to treat PTSD or suicide on both PTSD- and suicide-related outcomes. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and a total of 33 articles met the full inclusion criteria: 23 examining PTSD treatments, four examining suicide-focused treatments, and six examining combined treatments. PTSD and combined treatments reduced both PTSD- and suicide-related outcomes, with most studies focusing on cognitive processing therapy or prolonged exposure. Suicide-focused treatments (e.g., cognitive therapies for suicide prevention) also reduced suicide-related outcomes, but the findings were mixed for their impact on PTSD-related outcomes. Overall, PTSD treatments had the most support, primarily due to a larger number of studies examining their outcomes. This supports current clinical guidelines, which suggest utilizing PTSD treatments for individuals who have PTSD and are at risk for suicide. Suicide-focused and combined treatments also appeared to be promising formats, although additional research is needed. Future research should seek to compare the effectiveness of the approaches to the treatment of PTSD and suicidal thoughts and behaviors concurrently as well as to inform guidelines aimed at supporting decisions about the selection of an appropriate treatment approach.

ABSTRACT

OBJECTIVES: Previous research has found that many incarcerated individuals have mental health conditions and that incarcerated women may be at elevated risk. These individuals have been shown to experience mental health concerns shortly after their release, but little is known about their mental health later in life. This study compared depressive symptoms in older adults with and without a history of incarceration and examined the impact of gender on this relationship. METHOD: Data from 160 pairs of adults aged 65 or older (82.5% male, mean age = 73.4 years) who participated in the 2012 wave of the Health and Retirement Study (HRS) was utilized. Older adults with a history of incarceration were matched to those without based on age, gender, race, and education level. Depressive symptoms (CES-D) of older adults with and without a history of incarceration were compared using a repeated-measures ANOVA. RESULTS: The main effect of incarceration history (p=.001, partial eta2=.07) and the interaction between incarceration history and gender (p=.01, partial eta2=.04) were significant. Follow-up analyses revealed that the difference between depressive symptoms for older women with and without a history of incarceration was significant (p=.02, d = 0.69), whereas the difference for older men was not significant (p=.19, d = 0.16). CONCLUSIONS: Findings suggest older adults with a history of incarceration report more depressive symptoms than those without and that the effect is seen among older women. Negative effects of incarceration on mental health may therefore persist into later life, highlighting the importance of pre- and post-release mental health services.

ABSTRACT

OBJECTIVE: Racial disparities across various domains of health care are a long-standing public health issue that affect a variety of clinical services and health outcomes. Mental health research has shown that prevalence rates of posttraumatic stress disorder (PTSD) are high for Black veterans compared with White veterans, and some studies suggest poorer clinical outcomes for Black veterans with PTSD. The aim of this study was to examine the impact of racial disparities longitudinally in the U.S. Department of Veterans Affairs (VA) residential rehabilitation treatment programs (RRTPs). METHODS: Participants included 2,870 veterans treated nationally in VA PTSD RRTPs in fiscal year 2017. Veterans provided demographic data upon admission to the program. Symptoms of PTSD and depression were collected at admission, discharge, and 4-month follow-up. Hierarchical linear modeling was used to examine symptom change throughout and after treatment. RESULTS: Black veterans experienced attenuated PTSD symptom reduction during treatment as well as greater depression symptom recurrence 4 months after discharge, relative to White veterans. CONCLUSIONS: This study adds to the body of literature that has documented poorer treatment outcomes for Black compared with White veterans with PTSD. Although both Black and White veterans had an overall reduction in symptoms, future research should focus on understanding the causes, mechanisms, and potential solutions to reduce racial disparities in mental health treatment.

ABSTRACT

In June 2021, a condominium in Florida collapsed, with the loss of 98 lives. Search and rescue teams spent 2 weeks, recovering the victims. This study's objective was to assess the presence of psychological symptoms that might emerge in the following months, using the PTSD Checklist for DSM-5 (PCL-5), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder - 7 (GAD-7), Suicide Cognitions Scale-Short (SCS-S), and the Insomnia Severity Index (ISI). A monthly survey conducted for 3 months found that overall, mean scores on these measures did not indicate significant emotional distress. We then compared the scores when the group was divided into responders who recovered human remains and those who did not. Scores were significantly higher among the subgroup that recovered human remains. Fifty-three percent (53%) of this sub-group met the cut-off score for a provisional diagnosis of PTSD, depressive disorder or generalized anxiety disorder-15% met the cut-off score criteria on the PCL-5 for probable PTSD, 36.8% for probable depressive disorder on the PHQ-9, and 26.3% for probable generalized anxiety disorder on the GAD-7. The results are consistent with other investigations examining mental health after mass disasters. Specifically, not all first responders will develop emotional distress but certain recovery activities may put some responders at higher risk, with a percentage displaying psychological distress. The results emphasize the need to assess the impact of these events on the mental health of first responders and to consider strategies to prevent or mitigate the development of impairing psychopathology.

ABSTRACT

BACKGROUND: Identifying and enhancing protective beliefs is essential in reducing suicide risk among military-affiliated individuals. The goal of this study was to examine if specific reasons for living impact the relationship between PTSD and suicidal cognitions among military-affiliated individuals in primary care settings. METHODS: Participants included 2,685 U.S. military personnel and their adult beneficiaries recruited from primary care clinics. Participants completed the Primary Care Posttraumatic Stress Disorder Screen, Suicide Cognitions Scale, and Brief Reasons for Living Inventory. RESULTS: Responsibility to family and survival and coping beliefs-were related to suicidal cognitions with higher levels associated with less suicidal cognitions and a weaker relationship between PTSD and suicidal cognitions. By contrast, fear of suicide and fear of social disapproval were associated with more suicidal cognitions, and the link between positive PTSD screen and suicidal cognitions was stronger for individuals with higher levels of fear of social disapproval. Moral objection did not predict suicidal cognitions and did not moderate the relationship between PTSD and suicidal cognitions. LIMITATIONS: The limitations of the study include that measures were done in primary care and brief screeners were often used. Additionally, the study is cross-sectional in nature, whereas some of the symptoms and outcome variables likely fluctuate over time. CONCLUSIONS: Findings suggest not all reasons for living are not equally influential and, among military-affiliated individuals with a positive PTSD screen, bolstering reasons for living related to responsibility to family and survival and coping skills could be particularly impactful in reducing suicide cognitions.

ABSTRACT

Background: It has been suggested that current frontline posttraumatic stress disorder (PTSD) treatments are not effective for the treatment of moral injury and that individuals who have experienced morally injurious events may respond differently to treatment than those who have not. However, these claims have yet to be empirically tested. Objective: This study evaluated the rates of morally injurious event exposure and morally injurious index trauma and their impact on PTSD (PCL-5) and depression symptom (PHQ-9) reductions during intensive PTSD treatment. Method: Data from 161 USA military combat service members and veterans (91.3% male; mean age = 39.94 years) who participated in a 3-week Cognitive Processing Therapy (CPT)-based intensive PTSD treatment programme (ITP) was utilized. Morally injurious event exposure was established via the Moral Injury Event Scale (MIES). Index traumas were also coded by the treating clinician. Linear mixed effects regression analyses were conducted to examine if differences in average effects or trends over the course of treatment existed between veterans with morally injurious event exposure or index trauma and those without. Results: Rates of morally injurious event exposure in this treatment sample were high (59.0%-75.2%). Morally injurious event exposure and the type of index trauma did not predict changes in symptom outcomes from the ITP and veterans reported large reductions in PTSD (d = 1.35-1.96) and depression symptoms (d = 0.95-1.24) from pre- to post-treatment. Non-inferiority analyses also demonstrated equivalence across those with and without morally injurious event exposure and index events. There were no significant gender differences. Conclusions: The present study suggests that PTSD and depression in military veterans with morally injurious event exposure histories may be successfully treated via a 3-week CPT-based ITP.


Antecedentes: Se ha sugerido que los tratamientos actuales de primera línea para el trastorno de estrés postraumático (TEPT) no son efectivos para el tratamiento del daño moral y que las personas que han experimentado eventos moralmente dañinos pueden responder de manera diferente al tratamiento que las que no lo han hecho. Sin embargo, estas afirmaciones aún no se han probado empíricamente.Objetivo: Este estudio evaluó las tasas de exposición a eventos moralmente dañinos y trauma índice moralmente dañino y su impacto en las reducciones de síntomas del TEPT (PCL-5) y de depresión (PHQ-9) durante el tratamiento intensivo para TEPT.Método: Se utilizaron datos de 161 miembros y veteranos del servicio militar de combate de los Estados Unidos (91,3% hombres; edad promedio = 39,94 años) que participaron en un programa de tratamiento intensivo de TEPT (ITP en su sigla en inglés) basado en la Terapia de procesamiento cognitivo (CPT en su sigla en inglés) durante 3 semanas. La exposición a eventos moralmente dañinos se estableció mediante la Escala de eventos de daño moral (MIES en su sigla en inglés). Los traumas índice también fueron codificados por el médico tratante. Se llevaron a cabo análisis de regresión de efectos mixtos lineales para examinar si existían diferencias en los efectos promedio o las tendencias durante el curso de tratamiento en los veteranos con exposición a eventos moralmente perjudiciales o trauma índice y los que no.Resultados: Las tasas de exposición a eventos moralmente dañinos en esta muestra de tratamiento fueron altas (59,0% −75,2%). La exposición a eventos moralmente dañinos y el tipo de trauma índice no predijeron cambios en los resultados de los síntomas de la ITP y los veteranos reportaron grandes reducciones en los síntomas de TEPT (d = 1.35-1.96) y de depresión (d = 0.95-1.24) entre el pre- y post- tratamiento. Los análisis de no inferioridad también demostraron equivalencia entre aquellos con y sin exposición a eventos moralmente dañinos y eventos índice. No hubo diferencias de género significativas.Conclusiones: El presente estudio sugiere que el TEPT y la depresión en los veteranos militares con antecedentes de exposición a eventos moralmente dañinos pueden tratarse con éxito mediante un IPT basado en CPT de 3 semanas.

ABSTRACT

Intrataxonomic differences in terms of angiosperm suitability for herbivorous insects stem from variables such as plant structure, palatability, and chemistry. It has not yet been elucidated whether these differences also occur in terms of the bryophyte's suitability to bryophages. Hypnum cupressiforme Hedw. is a morphologically variable moss species frequently inhabited or fed by insects. In this investigation, we offered five morphotypes of H. cupressiforme to two bryophagous species of Byrrhidae (Coleoptera) to reveal whether the intrataxonomic variability affects beetles' preferences. The morphotypes were offered with preserved and removed spatial structures. There were no significant differences in morphotype preferences when spatial structures were preserved, although during the daytime, the beetles moved from the flat morphotype to the usual and turgid morphotypes. The beetles preferred the turgid morphotype when the spatial structures were removed. The results suggest that the spatial structure variations in the H. cupressiforme complex are accompanied by different chemical, physiological, or microscopic morphological profiles that are recognized by the bryophagous insects. Phylogenetic and epigenetic analyses can reveal multiple differences within the H. cupressiforme complex. Their interconnection with information about the preferences of bryophagous insects can help us to elucidate which of these differences are ecologically relevant.

ABSTRACT

OBJECTIVES: Duration, frequency, and intensity of nature exposure link to different physical and psychological benefits. The present study aimed to determine how time outdoors affected military veterans' posttraumatic stress disorder (PTSD) symptomology during PTSD treatment. METHOD: Hypotheses regarding time outdoors and the effect of program duration on PTSD symptoms were examined using multilevel models. The authors hypothesized that hours outdoors, both within- and between-persons, would predict reduced PTSD symptomology, program duration would predict reduced PTSD symptomology, and that hours outdoors and program duration would be significant when accounting for the other. RESULTS: The present study found that time outdoors correlated with participants' decreased PTSD symptomology: the more time participants spent outdoors, the greater the reduction in their PTSD symptoms. CONCLUSION: The effect of time outdoors was significant within-person, not between persons, suggesting that nature exposure may be used as an adjunct to traditional mental health treatment where exposure or dosage should be person-specific.

ABSTRACT

Suicides within the U.S. Armed Forces remain elevated. Brief cognitive behavioral therapy for suicide prevention (BCBT) has demonstrated preliminary efficacy as a psychotherapeutic intervention that reduces suicide attempts among U.S. Army Soldiers. The generalizability of BCBT's effects in other military groups and its underlying mechanisms of action remain unknown, however. The Marine Suicide Prevention and Intervention REsearch (M-SPIRE) study is designed to test the efficacy of BCBT for the prevention of suicide attempts among active duty U.S. Marines with recent suicidal ideation or attempts and to identify potential mechanisms of change contributing to BCBT's effects. In this protocol paper, we describe M-SPIRE's rationale and methods with a particular emphasis on measuring treatment fidelity and BCBT's hypothesized mechanisms of action.

ABSTRACT

Individuals with posttraumatic stress disorder (PTSD) are at increased risk for suicidal thoughts and behaviors; however, clinicians often report apprehension about recommending trauma-focused therapy to patients with an increased risk of suicide. The present study aimed to evaluate the safety, tolerability, and response to cognitive processing therapy (CPT) among a sample of military veterans with PTSD and increased suicide risk. A secondary aim was to provide a clinically useful definition of high suicide risk. Chart review was used to classify the suicide risk level of 290 veterans who participated in CPT at a Veterans Affairs clinic. Treatment outcomes in veterans with different suicide risk levels were also gathered and compared. Over 50% (n = 155) of the sample demonstrated increased suicide risk, and 1.0% (n = 3) engaged in suicidal behavior after initiating treatment. To date, hospital records show no suicide deaths since 2016 among clinic patients who received CPT. Suicide risk level was not associated with CPT tolerability, and PTSD symptom change was equivalent across groups, ps = .085-.976. Veterans across groups reported clinically significant reductions in PTSD symptoms. The tested suicide risk categorization schemes performed similarly in differentiating the odds of CPT completion and PTSD symptom reduction. These results suggest that veterans with PTSD and an increased risk of suicide, including those with previous suicide attempts and current ideation, can tolerate and benefit from CPT. Additional variables must be considered to truly determine the acute and imminent suicide risk that would deem CPT to be contraindicated.

ABSTRACT

OBJECTIVE: India accounts for 36.6% of suicide-related deaths among women worldwide. One social determinant of suicide in India is gender-based violence (GBV), and it disproportionately affects women from poorer socioeconomic classes. Although Indian women from slums are at high risk of GBV, the direct and indirect relationships between types of GBV and suicidal ideation (SI) for Indian women remain unexplored. This study examined: (a) the direct associations between types of GBV and SI and (b) indirect associations between GBV and risk for SI through depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms. METHOD: Trauma-exposed Indian women were recruited (N = 112); 98 completed a trauma screen, PHQ-9, GAD-7, and PCL-5 in Hindi. Traumatic events were categorized as GBV overlapping with Criterion A trauma (CA-GBV), emotional/economic GBV without Criterion A (E-GBV), and Criterion A without GBV (CA). The relation between trauma types and SI was examined through the indirect role of depression, anxiety, and PTSD symptoms. RESULTS: Logistic regression analyses revealed that CA-GBV was associated with higher odds of SI than other trauma types. This relationship was explained through the indirect role of depression symptom severity after accounting for other trauma types, anxiety, and PTSD symptoms. CONCLUSION: Results align with research showing that CA-GBV is particularly pernicious and affects SI. While anxiety and PTSD symptoms are related to CA-GBV, results suggest the relative importance of depression severity in the relation between CA-GBV and SI. Screening for SI among GBV survivors and treating depression symptoms may reduce the risk of suicide. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

ABSTRACT

Background: Posttraumatic stress disorder (PTSD) is a significant problem. Clinical practice guidelines recommend evidence-based treatments (EBTs) including cognitive processing therapy (CPT) and prolonged exposure (PE) as first-line treatments. Training in EBTs for PTSD has often been limited to large-scale systems (e.g., U.S. Department of Veterans Affairs). Research has shown that veteran-serving community-based mental health providers have low rates of training and supervision in EBTs for PTSD, suggesting that training initiatives for these community providers are critical to increase accessibility. This study aimed to examine the reach of education about EBTs for PTSD and the initiation of EBT for PTSD treatment among veteran-serving community-based providers participating in a large-scale training initiative. Methods: Participants (N = 280) were community-based, licensed mental health providers who received training in CPT (67%) or PE (33%). Provider attitudes toward EBTs were measured with the Perceived Characteristics of Intervention Scale. Reach was calculated from provider self-reported follow-up survey data, including caseload total number of patients with PTSD, number of patients provided education on EBTs for PTSD, and patient initiation of EBT for PTSD. Reach was calculated for both education and EBT initiation. Results: Providers reported positive attitudes toward CPT and PE. Rates of education reach for EBTs for PTSD ranged from 30% to 76%, and rates of EBTs for PTSD initiation ranged from 11% to 35% over the 5-month follow-up period. CPT providers had higher rates of education and initiation earlier in the follow-up period, although differences in initiation rates diminished after 3 months posttraining. Conclusion: Overall, this study examined how large-scale, training programs can be used to increase the education reach and initiation reach of EBTs for PTSD among veteran-serving community-based providers. Future work should examine how best to augment these training programs to reduce the gap between education and implementation of EBTs for PTSD. Plain Language Summary: Posttraumatic stress disorder (PTSD) is a significant problem among veterans. Although there are effective treatments for PTSD, mental health providers in community settings rarely have access to training in these treatments. Training programs are designed to offer providers the necessary training and support to deliver the most effective therapies to their clients. In evaluating these programs, it is important to determine whether they increase the likelihood that providers will deliver the interventions in which they were trained. Valuable outcomes include the percentage of patients who were educated on the specific intervention and who began to receive it. The (STRONG STAR) Training stron Initiative is a large-scale, community-based program that specializes in training providers in two leading PTSD therapies: cognitive processing therapy and prolonged exposure. Participants received a 2-day workshop, online resources, and weekly consultation calls to aid in the delivery of the intervention in which they were trained. Consequently, a large number of clients on provider caseloads are now aware of these PTSD treatments, and many have chosen to receive them. It is clear that the components within the (STRONG STAR) Training Initiative increase providers' competency in delivering therapies that have been widely studied. Therefore, more community members with PTSD will have access to gold-standard care. More funding should be devoted toward competency-based training programs to increase the number of people who receive education about and who engage in delivering effective therapies. This approach will ensure high-quality care and increased quality of life for those seeking treatment from community providers.

ABSTRACT

COVID-19 presents significant social, economic, and medical challenges. Because COVID-19 has already begun to precipitate huge increases in mental health problems, clinical psychological science must assert a leadership role in guiding a national response to this secondary crisis. In this article, COVID-19 is conceptualized as a unique, compounding, multidimensional stressor that will create a vast need for intervention and necessitate new paradigms for mental health service delivery and training. Urgent challenge areas across developmental periods are discussed, followed by a review of psychological symptoms that likely will increase in prevalence and require innovative solutions in both science and practice. Implications for new research directions, clinical approaches, and policy issues are discussed to highlight the opportunities for clinical psychological science to emerge as an updated, contemporary field capable of addressing the burden of mental illness and distress in the wake of COVID-19 and beyond.
