ABSTRACT
Youth with intellectual and/or developmental disabilities (IDD) often struggle with depression and anxiety, which adversely impacts transition to adulthood. Integrated behavioral health care coordination, wherein care coordinators and behavioral health specialists collaborate to provide systematic, cost-effective, patient-centered care, is a promising strategy to improve access to behavioral health services and address factors that impact transition to adulthood, including depression/anxiety symptoms. Current care coordination models (e.g., Title V Maternal and Child Health Bureau [MCHB]) do not include behavioral health services. The CHECK (Coordinated HealthCarE for Complex Kids) mental health model, hereby refined and renamed BEhavioral Health Stratified Treatment (B.E.S.T.), is a behavioral health intervention delivery program designed for integration into care coordination programs. This study aims to determine whether an integrated behavioral health care coordination strategy (i.e., MCHB care coordination plus B.E.S.T.) would be more acceptable and lead to better youth health and transition outcomes, relative to standard care coordination (i.e., MCHB care coordination alone). Results would guide future investment in improving outcomes for youth with IDD. This study is a two-arm randomized clinical trial of 780 transition-aged youth with IDD (13-20 years) to evaluate the comparable efficacy of MCHB Care Coordination alone vs. MCHB Care Coordination plus B.E.S.T. on the following outcomes: 1) decreased symptoms and episodes of depression and anxiety over time; 2) improved health behaviors, adaptive functioning and health related quality of life; 3) increased health care transition (HCT) readiness; and 4) improved engagement and satisfaction with care coordination among stakeholders.

With as many as 13% of adolescents diagnosed with depressive disorders each year, prevention of depressive disorders has become a key priority for the National Institute of Mental Health (NIMH). Currently, we have no widely available interventions to prevent these disorders. To address this need, we developed a multi-health system collaboration to develop and evaluate the primary care based technology "behavioral vaccine," Competent Adulthood Transition with Cognitive-Behavioral Humanistic and Interpersonal Therapy (CATCH-IT). The full CATCH-IT program demonstrated evidence of efficacy in prevention of depressive episodes in clinical trials. However, CATCH-IT became larger and more complex across trials, creating issues with adherence and scalability. We will use a multiphase optimization strategy approach to optimize CATCH-IT. The theoretically grounded components of CATCH-IT include: behavioral activation, cognitive-behavioral therapy, interpersonal psychotherapy, and parent program. We will use a 4-factor (2x2x2x2) fully crossed factorial design with N = 16 cells (25 per cell, after allowing 15% dropout) to evaluate the contribution of each component. Eligible at-risk youth will be high school students 13 through 18 years old, with subsyndromal symptoms of depression. The study design will enable us to eliminate non-contributing components while preserving efficacy and to optimize CATCH-IT by strengthening tolerability and scalability by reducing resource use. By reducing resource use, we anticipate satisfaction and acceptability will also increase, preparing the way for an implementation trial.

Obstetric fistula is a serious complication that affects thousands of women in low-income countries. Women who suffer from obstetric fistulae are at risk of developing mental health problems, but to date most interventions have focused on repairing the physical consequences of fistulae through surgery. The goal of the current study is to develop an evidence-based intervention targeting symptoms of depression, anxiety, and trauma in women recovering from fistula repair surgery. First, hospital staff and patients awaiting surgery at a fistula hospital in Ethiopia participated in qualitative interviews to provide information on the mental health needs of women with fistulae, how the hospital tends to these women's psychological needs, and the training needs of staff members. Data from these interviews were used to develop the COFFEE intervention (CBT with Obstetric Fistula for Education and Empowerment). COFFEE is a modular, group intervention that teaches psycho-education, behavioral activation, relaxation, problem solving, cognitive restructuring, and includes a trauma narrative. Patients then participated in an open trial of the COFFEE intervention at the University of Gondar Hospital. Five separate groups were conducted with 24 women who were enrolled post-fistula repair surgery. Women completed pre-treatment self-report questionnaires, participated in group sessions conducted by nurses (with 8 sessions delivered across 10-14 days), and were assessed post-treatment and at 3-month follow-up. Results indicate a significant reduction on depression and anxiety symptoms scores across the three time points [F(2, 40) = 68.45, p < 0.001 partial η2 = 0.774]. Additionally, there was a significant decrease in traumatic stress scores from baseline to post-treatment [F(1.10, 21.98) = 100.51, p < 0.001 partial η2 = 0.834]. Feedback forms completed by nurses and patients suggest the intervention was well-received. Results of this open-trial suggest the COFFEE intervention is feasible, acceptable, and clinically beneficial to treat symptoms of depression, anxiety, and traumatic stress in women post-fistula repair surgery in a hospital setting.

The majority of mental, emotional, and behavioral (MEB) disorders have an initial onset before age 24, with 20% annual incidence, and with major depressive disorder (MDD) being the most common MEB. Health systems may be able to reduce costs by transitioning from the current treatment-focused model for MDD to a prevention model. However, evidence is needed for (1) the comparative effectiveness of a "scalable intervention" and (2) an implementation model for such a scalable intervention in the primary care setting. This paper describes a comparative effectiveness trial evaluating the efficacy of two evidence-based cognitive-behavioral prevention (CBP) programs: Teens Achieving Mastery over Stress (TEAMS), the "gold standard," group therapy model, and Competent Adulthood Transition with Cognitive Behavioral, Humanistic and Interpersonal Training (CATCH-IT), a scalable, self-directed, technology-based model. Eligible adolescents, age 13-19, are offered one of these two depression prevention programs across five health systems (30 clinics) in urban and suburban Chicago, IL, rural Western IL, and Louisville, KY. We are comprehensively evaluating patient-centered outcomes and stakeholder-valued moderators of effect versus baseline at two, six, 12, and 18-month assessment points. Using a hybrid clinical trial design that simultaneously examines the implementation process, the study is also assessing adolescents', parents', and providers' experiences (e.g., efficacy, time commitment, cultural acceptability) within each intervention approach.

Adolescents who experience negative life events may be at risk for depression, particularly those with psychosocial vulnerabilities. We investigate longitudinally the impact of vulnerability/protective factors on the relation between a large-scale negative life event, the COVID-19 pandemic, and depressive symptoms. Adolescents (N = 228, Mage = 14.5 years, 53% female, 73% white) self-reported depressive symptoms 2-4 months before the pandemic (Time 1), and again 2 months following stay-at-home orders (Time 2). At T2, adolescents also completed measures of vulnerability, protective factors, and COVID-19-related distress. Depressive symptoms increased at T2, and COVID-19 distress interacted with resilience and negative cognitive style in predicting increases in T2 depression. Focusing on vulnerability and protective factors in adolescents distressed by large scale negative life events appears crucial.

OBJECTIVE: Advances in implementation science have encouraged novel methods for disseminating and implementing evidence-based treatments. Mental health services offered to trauma-exposed students on college campuses are characterized by unique contextual, developmental, and cultural factors that must be considered to effectively disseminate and implement trauma-focused, evidence-based treatments (TF-EBTs). Informed by novel implementation designs, this project utilized a strategic stakeholder engagement method of creating a learning community to identify and adapt a TF-EBT for use in university counseling centers (UCCs). METHOD: Project leads convened campus and community stakeholders included UCC clinicians, administrators, student life professionals, and students, to join researchers in a reciprocal collaboration to work toward dissemination and implementation. These stakeholders participated in a learning community that reviewed, selected, and adapted a TF-EBT and other tools for dissemination and implementation to UCCs and other campus professionals. RESULTS: There were a number of benefits and challenges of using the learning community as a method of dissemination and implementation. Benefits included context-specific knowledge sharing, clarification of the scope of trauma among college students, creation of helpful tools, emphasis on cultural competence in TF-EBTs, and facilitating connections between professionals. Challenges included balancing flexibility with progress toward project goals and recruitment and retention of stakeholders. CONCLUSIONS: Stakeholder engagement is an integral component of dissemination and implementation efforts. The learning community method allowed for stakeholders to take an active part in adapting a TF-EBT for UCCs and can be utilized in other settings to aid in adoption and utilization of evidence-based treatments.

Approximately 20% of people will experience a depressive episode by adulthood, making adolescence an important developmental target for prevention. CATCH-IT (Competent Adulthood Transition with Cognitive-behavioral, Humanistic, and Interpersonal Training), an online depression prevention intervention, has demonstrated efficacy in preventing depressive episodes among adolescents reporting elevated symptoms. Our study examines the effects of CATCH-IT compared to online health education (HE) on internalizing symptoms in adolescents at risk for depression. Participants, ages 13-18, were recruited across eight US health systems and were randomly assigned to CATCH-IT or HE. Assessments were completed at baseline, 2, 6, 12, 18, and 24 months. There were no significant differences between groups in change in depressive symptoms (b = -0.31 for CATCH-IT, b = -0.27 for HE, p = 0.80) or anxiety (b = -0.13 for CATCH-IT, b = -0.11 for HE, p = 0.79). Improvement in depressive symptoms was statistically significant (p < 0.05) for both groups (p = 0.004 for CATCH-IT, p = 0.009 for HE); improvement in anxiety was significant for CATCH-IT (p = 0.04) but not HE (p = 0.07). Parental depression and positive relationships with primary care physicians (PRPC) moderated the anxiety findings, and adolescents' externalizing symptoms and PRPC moderated the depression findings. This study demonstrates the long-term positive effects of both online programs on depressive symptoms and suggests that CATCH-IT demonstrates cross-over effects for anxiety as well.

OBJECTIVE: In accordance with Veterans Affairs (VA) policy, VA posttraumatic stress disorder (PTSD) clinics offer evidence-based treatments including cognitive processing therapy (CPT). To facilitate access to care, CPT is offered in both group and individual formats in many VA PTSD clinics. Group and individual delivery of CPT have been directly compared in active duty samples, but these findings have not been extended to VA populations. The present article directly compares the effectiveness of group and individual CPT with a written trauma account (CPT+A) across two VA PTSD clinics. METHOD: Veterans (N = 465) completed initial evaluations and enrolled in either group CPT+A (N = 146) or individual CPT+A (N = 319). Self-report measures of PTSD and depression symptoms were collected at pre-, mid-, and posttreatment; combined across treatment sites; and analyzed using hierarchical linear modeling. RESULTS: PTSD and depression symptoms reduced significantly over the course of group and individual CPT+A. Medium treatment effects were found for group CPT+A (d = .66 for PTSD, d = .68 for depression), and large treatment effects were found for individual CPT+A (d = .96 for PTSD, d = .79 for depression). CONCLUSION: Individual CPT+A led to significantly greater PTSD and depression symptom reduction than group CPT+A, indicating that in VA outpatient PTSD clinic settings, individual CPT+A may be a more effective approach than group CPT-A. In addition, PTSD symptoms reduced significantly more for Caucasian veterans than for African American veterans during CPT+A, indicating the importance of providing culturally competent trauma-focused care.

OBJECTIVE: Violence is a salient concern among veterans, yet relationships between psychiatric comorbidity, social networks, and aggression are poorly understood. We examined associations between biopsychosocial factors (substance use, posttraumatic stress disorder [PTSD], and social network behaviors) with aggression. METHOD: We recruited veterans endorsing past-year aggression and substance use (N = 180) from Department of Veterans Affairs outpatient treatment clinics. Main and interaction effects between probable PTSD, substance use, social network violence and substance use, and veteran violence were examined with negative binomial regressions-specifically, physical aggression toward a relationship partner (PA-P), physical injury of a partner (PI-P), physical aggression toward nonpartners (PA-NP), and physical injury of nonpartners (PI-NP). RESULTS: Alcohol use yielded consistent main effects. PTSD and social network violence demonstrated main effects for PA-NP and PI-NP. PTSD and social network violence interacted to predict PA-P such that social network violence appeared salient only in the context of PTSD. PTSD was associated with PI-P, PA-NP, and PI-NP in social network substance use models. In the PA-P model including social network substance use, veterans with PTSD reported greater PA-P in the context of greater social network substance use, whereas veterans without PTSD endorsed PA-P concurrent with greater alcohol frequency. For PI-P, PTSD interacted with alcohol to predict a greater likelihood of partner injury in the context of social network substance use. CONCLUSIONS: Investigated variables demonstrated unique associations within the context of specific relationships and the severity of behaviors. Overall, the findings underscore the importance of biopsychosocial models for understanding veteran violence. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

OBJECTIVE: Universities have demonstrated growing awareness of students impacted by interpersonal violence (e.g., sexual and physical assault) and veterans/service-members with combat-related trauma because of their sizable presence on campuses and unique vulnerabilities. This study sought to describe impacts of these two forms of trauma exposure on students' mental health and academic functioning and to compare mental health service utilization among students based on their experiences of trauma exposure. METHOD: To acquire a large, national sample of college students, we examined archival data from the Fall 2015 American College Health Association National College Health Assessment, a yearly, web-based survey which represented a sample of 19,861 students from 40 institutions. RESULTS: Twenty percent of the students had experienced interpersonal victimization in the last 12 months, combat exposure, or both. Compared with other groups, interpersonal violence survivors reported the most negative impacts on mental health and interference with academic performance. Service utilization rates among trauma-exposed students ranged from 52% to 84%, and students who had experienced recent interpersonal violence were the most likely to have received services. CONCLUSIONS: With a national sample, this study confirms that trauma-exposed students report poor mental health. Service utilization is high among this population, but campus-based mental health services appear to remain underutilized. Outreach efforts by student life professionals and campus clinicians targeting demographic subgroups could enhance utilization and accessibility of campus resources.

OBJECTIVE: This study sought to identify patient characteristics and care processes related to reengagement in VA psychotherapy. METHODS: Using national VA data, a retrospective cohort was constructed (N=24,492) of veterans who received a new PTSD diagnosis in FY08/FY09 and attended only one to five PTSD psychotherapy sessions. A nested case-control study was conducted comparing veterans who reengaged in psychotherapy (n=9649) in a 1:5 ratio with those who did not reengage by the end of FY12. Conditional logistic regression models were run to examine differences in sociodemographic, mental health, and service utilization factors between cases and controls. RESULTS: Among veterans in the study cohort, 39.4% reengaged in psychotherapy. In adjusted analyses, all measured types of health system encounters (primary care [OR=1.61], primary care mental health [OR=1.61], non-PTSD psychotherapy [OR=1.76], other non-PTSD mental health care [OR=1.43], other non-psychotherapy PTSD care [OR=3.31], emergency room [OR=1.14], and psychiatric hospitalization [OR=1.56]) were related to greater odds of reengagement in PTSD psychotherapy. CONCLUSIONS: Veterans' receipt of a broad range of care services may play an important role in reengagement in PCT psychotherapy, suggesting providers across care settings should be knowledgeable in how to support a Veteran's return to psychotherapy for PTSD.

Trauma history and increased exposure to combat and sexual trauma may account for heightened rates of PTSD among military populations. This study assessed trauma type and exposure history, diagnostic impressions, and PTSD severity in a large clinical dataset (n = 2463) of veterans presenting for PTSD evaluation at a Midwestern VA Medical Center between the years 2006 and 2013. The degree of lifetime trauma exposure was pronounced, with approximately 76% of the sample reporting exposure to at least four traumatic events. Higher numbers of lifetime trauma and higher levels of combat exposure were associated with more severe PTSD symptoms. Sexual trauma and combat trauma were more predictive of PTSD than other trauma types. Sexual trauma was associated with more severe PTSD than combat and other trauma.

BACKGROUND: Risk factors of violence perpetration in veterans include substance use and posttraumatic stress disorder (PTSD); however, it is unknown whether these factors are associated with greater risk for partner or non-partner violence. This study investigated the associations between probable PTSD, heavy drinking, marijuana use, cocaine use, and partner and non-partner violence perpetration. METHODS: Self-report questionnaires assessing past-year partner and non-partner aggression (CTS2) as well as past-month substance use (SAOM), probable PTSD (PCL-C), and probable depression (PHQ-9) were administered to 810 substance using veterans entering VA mental health treatment. RESULTS: In bivariate analyses, probable PTSD in substance using veterans was associated with violence perpetration (partner physical, χ2=11.46, p=0.001, φ=0.12; non-partner physical, χ2=50.64, p<0.001, φ=0.25; partner injury, χ2=6.41, p=0.011, φ=0.09; non-partner injury, χ2=42.71, p<0.001, φ=0.23). In multiple logistic regression analyses that adjusted for sociodemographic characteristics, probable PTSD was independently associated with non-partner physical (odds ratio [OR], 2.82; 95% confidence interval [CI], 1.97-4.05) and injury aggression (OR, 3.96; CI, 2.56-6.13). Cocaine and heavy drinking were independently associated with non-partner physical and injury aggression and non-partner injury aggression respectively. CONCLUSIONS: The results provide evidence that probable PTSD, heavy drinking, and cocaine use are associated with increased risk of non-partner violence perpetration in substance using veterans. These results underscore the importance of screening for PTSD symptoms and violence perpetration towards non-partners in substance using veterans presenting for treatment.

Rumination, defined as repetitive, negative, self-focused thinking, is hypothesized to be a transdiagnostic factor that is associated with depression, anxiety, and posttraumatic stress disorder (PTSD). Theory has suggested that in individuals with PTSD, rumination serves as a cognitive avoidance factor that contributes to the maintenance of symptoms by inhibiting the cognitive and emotional processing of the traumatic event, subsequently interfering with treatment engagement and outcome. Little is known about the neural correlates of rumination in women with PTSD. The current study utilized functional magnetic resonance imaging (fMRI) to examine neural correlates during an emotion interference task of self-reported rumination in women with PTSD. Women with PTSD (39 participants) were recruited at a university-based trauma clinic and completed a clinical evaluation that included measures of PTSD symptoms, rumination, and depressive symptoms, as well as a neuroimaging session in which the participants were administered an emotion interference task. There was a significant relationship between self-reported rumination and activity in the right orbital frontal cortex, BA 11; t(37) = 5.62, p = .004, k = 46 during the task. This finding suggested that women with PTSD, who had higher levels of rumination, may experience greater difficulty inhibiting negative emotional stimuli compared to women with lower levels of rumination.

Interpersonal trauma (IPT) against women can have dire psychological consequences including persistent maladaptive changes in the subjective experience of affect. Contemporary literature has firmly established heightened negative affect (NA) as a risk and maintenance factor for posttraumatic stress disorder (PTSD). However, the relationship between NA and PTSD symptoms is not well understood within IPT survivors, the majority of whom are female, as much of this research has focused on combat veterans. In addition, the connection between positive affect (PA) and PTSD symptoms has yet to be examined. With increased emphasis on "negative alterations in cognitions and mood . . ." as an independent symptom cluster of PTSD in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5), understanding the relationship between self-reported affectivity and the classic PTSD symptom clusters may be increasingly useful in differentiating symptom presentations of trauma-related psychopathology. The current study directly compared self-reported trait NA and PA with total severity and frequency cluster scores from the Clinician-Administered PTSD Scale (CAPS) in 54 female survivors of IPT who met criteria for PTSD. Results identify NA (but not PA) as a consistent predictor of total PTSD symptoms and, specifically, re-experiencing symptoms.

BACKGROUND: Post-Traumatic Stress Disorder (PTSD) is characterized by distinct behavioral and physiological changes. Given the significant impairments related to PTSD, examination of the biological underpinnings is crucial to the development of theoretical models and improved treatments of PTSD. METHODS: We used an attentional interference task using emotional distracters to test for top-down versus bottom-up dysfunction in the interaction of cognitive-control circuitry and emotion-processing circuitry. A total of 32 women with PTSD (based on an interpersonal trauma) and 21 matched controls were tested. Event-related functional magnetic resonance imaging was carried out as participants directly attended to, or attempted to ignore, fear-related stimuli. RESULTS: Compared to controls, patients with PTSD showed hyperactivity in several brain regions, including the amygdala, insula, as well as dorsal lateral and ventral PFC regions. CONCLUSIONS: These results are consistent with previous studies that have higher amygdala and insular activation in PTSD subjects. However, inhibition of suppression of PFC regions is inconsistent with the fear circuitry model hypothesized by prior research. We suggest that the specific emotional conflict task used appears to target implicit or automatic emotional regulation instead of explicit or effortful emotional regulation. This is particularly relevant as it posited that emotional regulatory difficulties in anxiety disorders such as PTSD appear to occur in implicit forms of emotion regulation.
ABSTRACT
This study examined posttraumatic growth in 30 male veterans captured and held as prisoners of war during the Vietnam War. Participants were assessed with structured diagnostic interviews administered by trained clinicians as well as with the Posttraumatic Growth Inventory (PTGI) and other questionnaires measuring dispositional optimism, religious coping, social supports, and purpose in life. Mean age (standard deviation-SD) of participants was 66.7 (6.0) years. Mean total PTGI score (SD) was 66.3 (17.5), indicating a moderate degree of posttraumatic growth. The most strongly endorsed items corresponded to the Appreciation of Life and Personal Strength factors. The group as a whole was optimistic and reported moderate use of positive religious coping. Posttraumatic growth did not significantly differ in repatriates with and without psychopathology, but it was significantly positively correlated with dispositional optimism. In the final regression model, length of captivity and optimism were significant predictors of posttraumatic growth. Our findings confirm that it is possible to achieve long-lasting personal growth even in the face of prolonged extreme adversity. Prospective studies are needed to further evaluate whether pre-existing traits such as optimism can predict growth after trauma.
