RESUMO
BACKGROUND: The role of interpersonal relationship functioning in trauma recovery is well-established. However, much of this research has been done with cross-sectional samples, often years after trauma exposure, using self-report methodology only, and is focused on intimate relationship adjustment. METHODS: The current study investigated the longitudinal associations between interpersonal (intimate and non-intimate) relationship functioning and clinician- and self-reported posttraumatic stress disorder (PTSD) symptoms in 151 recently (within the past 6 months) traumatized individuals. Participants were assessed at four time points over 1 year. RESULTS: Approximately 53% of the sample was diagnosed with PTSD at initial assessment, with declining rates of diagnostic status over time to 16%. Latent difference score (LDS) modeling revealed nonlinear declines in both clinician-assessed and self-reported PTSD symptom severity, with faster declines in earlier periods. Likewise, LDS models revealed nonlinear declines in negative (conflict) aspects of interpersonal relationship functioning, but linear declines in positive (support, depth) aspects. The relationship between PTSD and relationship functioning differed for clinician- and self-reported PTSD. Bivariate LDS modeling revealed significant cross-lagged effects from relationship conflict to clinician-assessed PTSD, and significant cross-lagged effects from self-reported PTSD to relationship conflict over time. CONCLUSIONS: These results highlight that the variability in prior results may be related to the method of assessing PTSD symptomatology and different relational constructs. Implications for theory and early intervention are discussed.

OBJECTIVE: Theoretical and conceptual models of posttraumatic stress disorder (PTSD) symptom progression in youth have identified social functioning as having a central influence. Yet a dearth of research has examined the bidirectional temporal associations between PTSD symptoms and social functioning. METHOD: This study is the first to investigate these temporal dynamics in a sample of adolescents in trauma-informed residential treatment (N= 453; M age = 15.77 [range = 12.12-18.95], SD = 1.55; 57.2% female). The UCLA PTSD Reaction Index for DSM-5 was analyzed as a measure of youth-reported PTSD symptoms and the Interpersonal Problems subscale of the Children's Depression Inventory, 2nd edition was analyzed as a measure of youth-reported social functioning issues. The Social Problems subscale from the Child Behavior Checklist was analyzed as a measure of clinician-reported social functioning difficulties. Measures were completed at baseline and then approximately every three months for the duration of treatment. Multivariate lagged analyses were used to examine the temporal, bidirectional associations between PTSD symptoms and social functioning. RESULTS: Results indicated that while controlling for length of stay, trauma exposure, age, and gender, reductions in PTSD symptoms predicted subsequent reductions in social functioning problems across both measures (prs = .12-.16), and that improvement in interpersonal relationships predicted subsequent decreases in PTSD symptoms (pr = .12). CONCLUSIONS: Taken together, these findings highlight the importance of healthy social relationships for decreasing adolescent's psychological distress. Treatments that include components that target social functioning in addition to symptom reduction may maximally benefit youth with trauma-related psychopathology.

BACKGROUND: The unified protocol (UP) is a promising transdisgnostic treatment for emotional disorders; limited data exists with trauma-exposed populations. This study compared effectiveness of the UP, presented centered therapy (PCT), and treatment as usual (TAU) in trauma-exposed veterans presenting to routine care. METHOD: Trauma-exposed veterans with one or more emotional disorder diagnoses participated in a pilot hybrid-1 effectiveness/preimplementation study. Thirty-seven male and female veterans were randomized to one of three conditions. RESULTS: Multilevel growth curve modeling demonstrated improvement over time across conditions with large effect sizes (range: -2.15 to -3.32), with the UP demonstrating the greatest change. The between group effect sizes for reductions in number of comorbid diagnoses were medium to small and statistically significant (TAU and UP, d = 0.49, p = .056; TAU and PCT d = 0.18, p = .166, UP and PCT d = 0.31, p = .229). Only the UP led to a decrease in the number of comorbid diagnoses (d = -0.71). Psychosocial functioning varied by group, with slight increases in impairment in PCT and TAU, and medium effect size reduction in the UP. Only the UP exhibited significant decreases in self-reported anxiety and depression. Between group differences for UP and PCT were medium to large and statistically significant for depression across two measures (d = -0.72 to d = -1.40). CONCLUSIONS: This represents the first trial examining effectiveness of the UP, PCT, and TAU in trauma-exposed veterans. Despite a small sample, large effect size differences demonstrated promising advantages for the UP. Trial Registration Number: NCT02944994.

OBJECTIVES: Recent initiatives have highlighted the importance of investigating clinically relevant variations in social processes that contribute to mental illness. Surprisingly little research has examined the associations between socially and clinically relevant transdiagnostic factors, such as social anxity (SA) and rejection sensitvity (RS), on theory of mind (ToM) decoding ability. METHODS: The Reading the Mind in the Eyes Task and self-report measures of SA and RS were completed by 199 adult participants. RESULTS: Linear regression analyses suggest a specific difficulty decoding positive emotion associated with SA and global decrements in ToM associated with RS that may reflect a negative interpretation bias. CONCLUSIONS: These findings may have important implications for understanding how those with SA and RS perceive and navigate social interactions, which may contribute to the maintenance of symptoms and decreased psychosocial functioning.

The primary method of training for individual licensed mental health professionals is continuing education (CE). Despite the promise of CE as a vehicle for training clinicians in evidence-based practices, only a handful of studies have examined the efficacy of trainings delivered in the CE context. Moreover, these studies have focused on a few very specific therapeutic approaches. There is a growing body of evidence supporting Acceptance-based Behavior Therapy (ABBT) as a treatment for generalized anxiety disorder (GAD) and related disorders. Training workshops aimed at disseminating ABBT are regularly conducted across and outside the United States, yet the effectiveness of these trainings is unknown. The goal of this study was to examine learning outcomes among licensed mental health professionals following a six-hour CE training in ABBT. Data were collected at baseline, post-training, and at three-month follow-up. Participants demonstrated a statistically significant increase in learning on an ABBT Knowledge Questionnaire and in their coded responses to client scenarios from baseline to follow-up, although there was a significant decline in knowledge between post and follow-up. Beyond baseline ABBT knowledge, attitude towards evidence-based practice was the only predictor of change in knowledge over time.

Effective interventions for generalized anxiety exist, but barriers to treatment prevent their broad dissemination. Commercially available self-help materials may help bridge this gap, but few have been empirically evaluated. This study compared self-reported change in generalized anxiety symptomology and associated problems between community members with excessive worry who were randomly assigned to receive the Worry Less, Live More: The Mindful Way through Anxiety Workbook (n = 35) and those in a delayed condition (n = 29). Participants in the workbook condition reported significantly greater reductions between baseline and 11-week follow-up in self-reported worry (η2 =.15), general anxiety/tension (η2 =.13), and anxiety (η2 =.24) than those in the delayed condition, although no statistically significant differences across condition on changes in depression, functional impairment or acceptance were detected. This pilot study provides support for continued research examining the efficacy of acceptance-based behavioral therapy delivered in a self-help format.

Risk for traumatic sequelae is conveyed directly by risk factors (i.e., exposure to trauma), and via the disruption of developmental competencies. Exposure to caregiver trauma is an especially salient risk factor, as its early and pervasive nature is likely to undermine multiple facets of development, most notably the emergence of cognitive controls (i.e., executive function [EF]). Deficits in EF have been observed among youth exposed to multiple types of trauma and are associated with a range of functional impairments, posttraumatic stress symptoms (PTSS), and behavioral disorders; they represent a mechanism by which the negative impact of caregiver trauma is conveyed. This study included 672 youth in residential placement, and examined the associations between both caregiver and noncaregiver trauma, measured by the Trauma History Profile (THP); executive dysfunction, measured by the Behavioral Inventory of Executive Function (BRIEF); PTSS, measured by the UCLA Posttraumatic Stress Disorder (PTSD) Reaction Index (PTSD-RI); and externalizing and internalizing problems, measured by the Child Behavior Checklist (CBCL). A structural equation model demonstrated direct associations between caregiver trauma and PTSS, ß = .15; noncaregiver trauma and externalizing problems, ß = .14; gender and PTSS, ß = .26, externalizing problems, ß = .12, and internalizing problems, ß = .26; and age and externalizing problems, ß = -.11. We observed indirect effects via deficits in EF between caregiver trauma and PTSS, ß = .04 and externalizing problems, ß = .19. Results indicate for screening for executive dysfunction among trauma-impacted youth is needed, as it represents a critical therapeutic target.

EEG Biofeedback (also known as neurofeedback) has been in use as a clinical intervention for well over 30 years; however, it has made very little impact on clinical care. One reason for this has been the difficulty in designing research to measure clinical change in the real world. While substantial evidence exists for its efficacy in treating attention deficit/hyperactivity disorder, relatively little evidence exists for its utility in other disorders including posttraumatic stress disorder (PTSD). The current study represents a "proof-of-concept" pilot for the use of neurofeedback with multiply-traumatized individuals with treatment-resistant PTSD. Participants completed 40 sessions of neurofeedback training two times per week with sensors randomly assigned (by the study coordinator, who was not blind to condition) to sensor placements of either T4-P4 or T3-T4. We found that neurofeedback significantly reduced PTSD symptoms (Davidson Trauma Scale scores averaged 69.14 at baseline to 49.26 at termination), and preceded gains in affect regulation (Inventory of Altered Self-Capacities-Affect Dysregulation scores averaged 23.63 at baseline to 17.20 at termination). We discuss a roadmap for future research.

OBJECTIVE: Both executive dysfunction (ED), measured by performance-based tasks, and dysexecutive behavior (DB), measured by behavioral rating scales, contribute to late-life depression and comorbid disability. There is a modest positive association of ED and DB, but less is known about their relative contributions to core aspects of neuropsychiatric conditions and whether they provide unique or redundant information. METHODS: Latent variable analyses were applied to ED, DB, depression, and disability data from 220 older patients with major depression and ED who had been enrolled in a psychosocial treatment study of depression. ED measures included the Trail Making Test, part B, Stroop Color Word Interference Test, and Hopkins Verbal Learning Test-Trail 1. The ED scale from the Frontal Systems Behavior Scale, self and other-rated, served as the ratings-based measure of DB. RESULTS: The measurement model, with all four latent variables related to one another, demonstrated good fit (RMSEA=0.06). In the structural models, DB was associated with both depression (ß=0.61) and disability (ß=0.42), whereas ED was associated with depression (ß=0.43) but not disability (ß=0.16). Social problem-solving accounted for 49% of the influence of DB on late-life depression, whereas ED was not related to social problem-solving. CONCLUSION: ED and the lesser studied DB measures offer unique and complementary information. DB was robustly associated with late-life depression and disability. Patients with depression and ED may be more likely to develop disability when they exhibit DB and social problem-solving difficulties.

This study examined the effect of child sexual or physical abuse on brief cognitive-behavioral therapy treatments with adults with posttraumatic stress disorder (PTSD). We analyzed secondary data from two randomized controlled trials (Resick, Nishith, Weaver, Astin, & Feuer, 2002; Resick et al., 2008) that included women with PTSD who did or did not have child sexual abuse (CSA) or child physical abuse (CPA) histories to determine whether childhood abuse impacted dropout rate or reduction in PTSD symptoms. In Study 1, presence, duration, or severity of CSA was not associated with dropout; however, frequency of CSA significantly predicted dropout (OR = 1.23). A significant CPA Severity × Treatment Group interaction emerged such that CPA severity was associated with greater dropout for prolonged exposure (PE; OR = 1.45), but not cognitive processing therapy (CPT; OR = 0.90). Study 2 found no differences in dropout. Study 1, comparing CPT and PE among women who experienced at least 1 rape found no differences in outcome based on childhood abuse history (rp (2) s = .000-.009). Study 2, a dismantling study of CPT with women seeking treatment for adult or child sexual or physical abuse found that for those with no childhood abuse, CPT-C, the cognitive-only version of CPT, had an advantage, whereas both forms of CPT worked best for those with higher frequency of childhood abuse; the effect size was small.

This study examined the relationship between change in posttraumatic stress disorder (PTSD) symptoms over the course of PTSD treatment and the association with changes in general physical health symptoms. Both positive health habits (e.g., exercise) and negative (e.g., smoking), were examined to determine if they accounted for the association between changes in PTSD severity over time and changes in physical health. Participants were 150 women seeking treatment for PTSD. Latent growth curve modeling indicated a substantial relationship (R (2) = 34%) between changes in PTSD and changes in physical health that occurred during and shortly following treatment for PTSD. However, there was no evidence to suggest that changes in health behaviors accounted for this relationship. Thus, PTSD treatment can have beneficial effects on self-reported physical health symptoms, even without direct treatment focus on health per se, and is not accounted for by shifts in health behavior.

BACKGROUND: Suicide is a significant public health problem. Although various studies have found evidence of posttraumatic stress disorder (PTSD) as a risk factor for suicidal behaviors, no study has examined whether or not PTSD treatment decreases suicidal thoughts. This study aims to fill this gap in the literature by examining changes in suicidal ideation over the course of a randomized clinical trial, which compared two widely used treatments for PTSD-cognitive processing therapy (CPT) and prolonged exposure (PE). METHODS: Data from 163 trial participants over five time points (pre- and posttreatment, 3 and 9 months posttreatment, and 5-10 years posttreatment) were examined using multilevel growth curve analyses to determine if reductions in PTSD symptoms during treatment were associated with reductions in suicidal ideation. Major depression diagnosis and hopelessness were controlled. RESULTS: Suicidal ideation decreased sharply during treatment with continued, but more subtle decreases, during the follow-up period. These decreases were associated with decreases in PTSD symptoms over the course of treatment. These associations were not accounted for by depression diagnoses at the start of the study or changes in hopelessness over the course of treatment. CONCLUSIONS: Two widely used, effective treatments for PTSD reduce suicidal ideation. CPT exhibited a larger influence on suicidal ideation than PE, although the magnitude of the difference was small in size. Inclusion of PTSD screening and treatment could enhance suicide prevention efforts.

The mediating role of posttraumatic stress symptomatology (PSS) on the association between warzone exposure and physical health symptoms in 7 bodily systems (cardiovascular, dermatological, gastrointestinal, genitourinary, musculoskeletal, neurological, and pulmonary) was examined. We also examined if mediation effects varied as a function of sex. A sample of 317 U.S. Gulf war veterans was assessed for warzone exposure, PSS, and physical health symptoms 10 years after deployment. PSS was significantly associated with postdeployment physical health in all symptom categories when accounting for predeployment health (with effect sizes ranging from a 1.27-1.64 increase in the likelihood of postdeployment physical health symptoms with a 1 standard deviation increase in the PSS symptoms). PSS severity mediated the relationship between warzone exposure and postdeployment symptoms in all physical health domains (with percent mediation ranging 44%-75%). A significant Warzone Exposure × PSS interaction emerged for 5 outcomes such that the effect of PSS on physical health was stronger for veterans reporting lower warzone exposure. No significant interactions with sex emerged. These findings suggest the important influence of PSS on physical health symptoms for both men and women.

Psychological distress and coping strategies following intimate partner violence (IPV) victimization may impact survivors' risk for future IPV. The current study prospectively examined the impact of distinct posttraumatic stress disorder (PTSD) symptom clusters (reexperiencing, avoidance, numbing, and hyperarousal), dissociation, and coping strategies (engagement and disengagement coping) on IPV revictimization among recently abused women. Women (N = 69) who were seeking services for IPV and experienced their most recent episode of physical IPV between 2 weeks and 6 months prior to study enrollment completed measures of physical IPV, psychological distress, and coping strategies at baseline and at 6-month follow-up. The women averaged 36 years of age and 67% of the sample was African American. Separate Poisson regression analyses revealed that PTSD hyperarousal symptoms, dissociation, engagement coping, and disengagement coping each significantly predicted physical IPV revictimization at the 6-month follow-up (with effect sizes ranging from a 1.20-1.34 increase in the likelihood of Time 2 physical IPV with a 1 SD increase in the predictor). When these significant predictors were examined together in a single Poisson regression model, only engagement and disengagement coping were found to predict physical IPV revictimization such that disengagement coping was associated with higher revictimization risk (1.29 increase in the likelihood of Time 2 physical IPV with one SD increase in disengagement coping) and engagement coping was associated with lower revictimization risk (1.30 decrease in the likelihood of Time 2 physical IPV with one SD increase in engagement coping). The current findings suggest that coping strategies are important and potentially malleable predictors of physical IPV revictimization.

IMPORTANCE: Alcohol dependence comorbid with posttraumatic stress disorder (PTSD) has been found to be resistant to treatment. In addition, there is a concern that prolonged exposure therapy for PTSD may exacerbate alcohol use. OBJECTIVE: To compare the efficacy of an evidence-based treatment for alcohol dependence (naltrexone) plus an evidence-based treatment for PTSD (prolonged exposure therapy), their combination, and supportive counseling. DESIGN, SETTING, AND PARTICIPANTS: A single-blind, randomized clinical trial of 165 participants with PTSD and alcohol dependence conducted at the University of Pennsylvania and the Philadelphia Veterans Administration. Participant enrollment began on February 8, 2001, and ended on June 25, 2009. Data collection was completed on August 12, 2010. INTERVENTIONS: Participants were randomly assigned to (1) prolonged exposure therapy plus naltrexone (100 mg/d), (2) prolonged exposure therapy plus pill placebo, (3) supportive counseling plus naltrexone (100 mg/d), or (4) supportive counseling plus pill placebo. Prolonged exposure therapy was composed of 12 weekly 90-minute sessions followed by 6 biweekly sessions. All participants received supportive counseling. MAIN OUTCOMES AND MEASURES: The Timeline Follow-Back Interview and the PTSD Symptom Severity Interview were used to assess the percentage of days drinking alcohol and PTSD severity, respectively, and the Penn Alcohol Craving Scale was used to assess alcohol craving. Independent evaluations occurred prior to treatment (week 0), at posttreatment (week 24), and at 6 months after treatment discontinuation (week 52). RESULTS: Participants in all 4 treatment groups had large reductions in the percentage of days drinking (mean change, -63.9% [95% CI, -73.6% to -54.2%] for prolonged exposure therapy plus naltrexone; -63.9% [95% CI, -73.9% to -53.8%] for prolonged exposure therapy plus placebo; -69.9% [95% CI, -78.7% to -61.2%] for supportive counseling plus naltrexone; and -61.0% [95% CI, -68.9% to -53.0%] for supportive counseling plus placebo). However, those who received naltrexone had lower percentages of days drinking than those who received placebo (mean difference, 7.93%; P = .008). There was also a reduction in PTSD symptoms in all 4 groups, but the main effect of prolonged exposure therapy was not statistically significant. Six months after the end of treatment, participants in all 4 groups had increases in percentage of days drinking. However, those in the prolonged exposure therapy plus naltrexone group had the smallest increases. CONCLUSIONS AND RELEVANCE: In this study of patients with alcohol dependence and PTSD, naltrexone treatment resulted in a decrease in the percentage of days drinking. Prolonged exposure therapy was not associated with an exacerbation of alcohol use disorder. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00006489.

OBJECTIVE: A confirmatory factor analysis (CFA) of the Adolescent Dissociative Experiences Scale (A-DES) that found a best-fitting three-factor model for a trauma-exposed sample was recently replicated; however, a post hoc bifactor CFA model fit the data better and identified a strong general factor. Only the general factor was associated with cumulative trauma exposure, but this association was small. METHOD: Structural equation modeling (SEM) and regression analyses were applied to the best-fitting three-factor bifactor model of dissociation found in the same sample of 1,157 treatment-seeking adolescents, most with high levels of trauma exposure, to further elucidate dissociation's construct validity and dimensionality. RESULTS: The general factor was positively yet differentially associated with psychosocial outcomes. A dissociation by age interaction emerged for internalizing problems, demonstrating that the positive association was stronger for older participants. Also, an age of trauma exposure onset by dissociation interaction emerged predicting depression, such that later trauma onset produced a stronger association between dissociation and depression. CONCLUSIONS: Traumas occurring in later adolescence may confer greater risk of dissociation. Differential psychosocial outcomes also reinforce why approaching dissociation from a developmental psychopathology lens is important, enhancing the model's generalizability.

OBJECTIVE: Research examining the factor structure of the Adolescent Dissociative Experiences Scale (A-DES) has yielded mixed findings. This study sought to further clarify the factor structure of the A-DES among youth with histories of exposure to multiple traumas and adversities. METHOD: We conducted a factor analysis of the A-DES using data from 1,157 treatment-seeking adolescents with histories of trauma exposure in order to expand understanding of dissociation's construct validity and provide the first attempt at post hoc analysis of trauma-impacted adolescents. RESULTS: A bifactor CFA model fit the data best and identified a strong general factor, supporting a unidimensional latent structure. Only the general dissociation factor was associated with cumulative trauma exposure, operationalized as the number of different types of exposure endorsed on the Trauma History Profile (THP), but this association was small. CONCLUSIONS: The study findings point toward a unidimensional conceptualization of dissociation. A developmental psychopathology framework is recommended for future research, allowing a nuanced and integrated approach to understanding dissociation and increasing generalizability across adolescents.

BACKGROUND: Trauma-informed residential care is an intensive intervention setting for youth, but research on its effectiveness is limited and yields mixed findings. OBJECTIVES: The study aims were to; 1) evaluate change over time of mental health (MH) symptoms over 21 months of trauma-informed residential care, and 2) examine the influence of demographic and risk factor variables (e.g. age, gender, trauma and placement history) on baseline symptoms and treatment response. PARTICIPANTS: A sample of 547 youth ages 12 to18 in trauma-informed residential care (M age = 15.84 (SD = 1.56), 43.2 % male) were examined, with notable attrition over the study period. METHOD: Latent curve analysis (LCA) was used to estimate MH symptom severity at intake and change during 21 months (8 assessments total, intake and every 3 months) of care. RESULTS: Trauma-informed residential care was associated with significant reductions in symptoms of PTSD (d = -0.76), depression (d = -0.59), dissociation (d = -0.60), psychological dysregulation (d = -0.94), and externalizing (d = -0.31), but not internalizing (d = 0.01) problems. Females had greater symptoms at intake across multiple indicators and showed equivalent or greater treatment response than males, although both groups improved. Neither cumulative trauma nor previous placement were associated with attenuated treatment response, but trauma history was positively associated with severity of multiple clinical measures at intake. CONCLUSIONS: Trauma-informed residential treatment can lead to reductions in clinical symptoms, even among multiply trauma-impacted youth. The extent of youth's trauma history did not negatively influence treatment response.

BACKGROUND: This secondary analysis of data from a randomized controlled trial of cognitive processing therapy (CPT) and its constituent components investigated whether dissociation decreased over the course of treatment primarily targeting symptoms of posttraumatic stress disorder (PTSD) and explored whether levels of dissociation predicted treatment outcome differentially by treatment condition. METHODS: An intention to treat sample of 150 women were randomized to CPT, cognitive therapy only (CPT-C) or written trauma accounts only (WA). Dissociation was measured by the dissociation subscale of the Traumatic Stress Inventory and the Multiscale Dissociation Inventory. RESULTS: Multilevel regression analyses revealed significant decreases in dissociation that did not vary as a function of treatment condition. Growth curve modeling revealed significant treatment condition by dissociation interactions such that the impact of pretreatment levels of dissociation impacted the treatment conditions differently. CONCLUSIONS: Women who endorsed low pretreatment levels of dissociation responded most efficiently to CPT-C, whereas women with the highest levels of dissociation, in particular high levels of depersonalization, responded better to CPT.

Complex posttraumatic stress disorder (CPTSD) has been proposed as a diagnosis for capturing the diverse clusters of symptoms observed in survivors of prolonged trauma that are outside the current definition of PTSD. Introducing a new diagnosis requires a high standard of evidence, including a clear definition of the disorder, reliable and valid assessment measures, support for convergent and discriminant validity, and incremental validity with respect to implications for treatment planning and outcome. In this article, the extant literature on CPTSD is reviewed within the framework of construct validity to evaluate the proposed diagnosis on these criteria. Although the efforts in support of CPTSD have brought much needed attention to limitations in the trauma literature, we conclude that available evidence does not support a new diagnostic category at this time. Some directions for future research are suggested.
