Enhancing social functioning in older veterans with PTSD: Rationale and design of an intervention and initial RCT.

BACKGROUND: Older Veterans with Posttraumatic Stress Disorder (PTSD) are often socially isolated and have complex comorbid physical health problems. Aging-related stressors can exacerbate PTSD symptoms. These factors contribute to greater impairment in social functioning and decreased quality of life (QoL). Evidence-based psychotherapies for PTSD often address these issues, but not all older Veterans with PTSD seek help for these challenges, some don't want to engage in trauma-focused treatment, some drop out prematurely, and some still have residual symptoms upon completion. Thus, additional interventions that directly target social functioning among older Veterans with PTSD are needed. METHODS: In this paper we describe the development of and feasibility evaluation plan for, "Enhancing Social Functioning for older Veterans with PTSD (ESVP)," a social functioning group intervention for older (>60 years) Veterans with PTSD. This project involved four phases of work: 1) Intervention development, 2) Review of intervention and potential modifications using focus groups, 3) Intervention pilot testing and modification, and 4) A randomized feasibility trial comparing the intervention with a support group control. Intervention modules address interpersonal relationships, effective communication, anger management, social skills, social support/activities, and behavioral activation. CONCLUSION: This project details the iterative process used to develop the ESVP intervention designed to enhance social functioning in older Veterans with PTSD, and to evaluate feasibility. Analyses are underway to examine feasibility of conducting ESVP with a sample of older Veterans with PTSD. Findings from the final project phase, the randomized feasibly trial, will inform the design and implementation of a future trial. CLINICALTRIALS: gov Identifier: NCT02803125.

A systematic review of written exposure therapy for the treatment of posttraumatic stress symptoms.

OBJECTIVE: Written exposure therapy (WET) is a brief treatment for posttraumatic stress disorder (PTSD), with an increasing number of studies published over the past several years. The current study conducted a systematic review to evaluate the current state of evidence for WET as a treatment for PTSD symptom severity. METHOD: Four databases were searched: PsycInfo, PTSDpubs, MEDLINE, and PubMed. Inclusion criteria included a peer-reviewed study of WET, a PTSD treatment outcome measure at pre- and posttreatment, and full-text available in English. RESULTS: Seventeen studies were identified for inclusion, seven of which were randomized controlled trials. Study sample sizes ranged from three to 277, with most studies (88%) examining adults. Five studies used a language translation version of WET, two studies examined a group format, and three studies examined PTSD symptom outcome when WET was delivered via telehealth. Within condition effect sizes for PTSD treatment outcome were moderate to large (d range = 0.48-6.45), and between condition effect sizes were large (d range = 1.05-5.25), except for three studies that included a trauma-focused treatment comparison condition (d range = 0.01-0.31). Dropout rates for WET were generally low, and less when compared with other trauma-focused treatments. CONCLUSIONS: The published studies indicate that WET is an efficacious and effective treatment for PTSD symptoms across a variety of samples, settings, and counties. Future work in this area should include investigation of the implementation and dissemination of WET. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Design of a hybrid implementation effectiveness cluster randomized controlled trial of delivering written exposure therapy for PTSD in underserved primary care settings.

INTRODUCTION: Posttraumatic stress disorder (PTSD) results in substantial costs to society. Prevalence of PTSD among adults is high, especially among those presenting to primary care settings. Evidence-based psychotherapies (EBPs) for PTSD are available but dissemination and implementation within primary care settings is challenging. Building Experience for Treating Trauma and Enhancing Resilience (BETTER) examines the effectiveness of integrating Written Exposure Therapy (WET) within primary care collaborative care management (CoCM). WET is a brief exposure-based treatment that has the potential to address many challenges of delivering PTSD EBPs within primary care settings. METHODS: The study is a hybrid implementation effectiveness cluster-randomized controlled trial in which 12 Federally Qualified Health Centers (FQHCs) will be randomized to either CoCM plus WET (CoCM+WET) or CoCM only with 60 patients within each FQHC. The primary aim is to evaluate the effectiveness of CoCM+WET to improve PTSD and depression symptom severity. Secondary treatment outcomes are mental and physical health functioning. The second study aim is to examine implementation of WET within FQHCs using FQHC process data and staff interviews pre- and post-intervention. Exploratory aims are to examine potential moderators and mediators of the intervention. Assessments occur at baseline, and 3- and 12-month follow-up. CONCLUSION: The study has the potential to impact practice and improve clinical and public health outcomes. By establishing the effectiveness and feasibility of delivering a brief trauma-focused EBP embedded within CoCM in primary care, the study aims to improve PTSD outcomes for underserved patients.

Predictors of dropout in cognitive processing therapy for PTSD: An examination of in-session treatment processes.

Dropout rates for treatments for adult posttraumatic stress disorder (PTSD) are high. Process research can reveal client factors during treatment that predict dropout. An observational coding system was used to code client processes in audio-recorded early sessions of cognitive processing therapy (CPT), a gold-standard treatment for PTSD. Data are from a randomized controlled noninferiority trial of CPT and written exposure therapy (WET), with higher rates of dropout in CPT than WET (39.7% vs. 6.4%). Participants in this study were 53 treatment-seeking adults with PTSD who were in the CPT arm of the trial and completed the CAPS-5 at pretreatment and at least one session. Of these, 15 (28.3%) dropped out of CPT early (completing ≤9 sessions) and 38 (71.7%) completed treatment. Sessions were coded with an observational coding system on a four-point scale (0 = absent to 3 = high) for maladaptive trauma-related responses (overgeneralized beliefs, ruminative processing, avoidance), affective engagement (negative emotions, physiological distress), and adaptive processing (cognitive emotional processing). Binary logistic regressions showed that more physiological distress and cognitive emotional processing predicted lower dropout, whereas more avoidance predicted higher dropout. Negative emotion, ruminative processing, and overgeneralization were not significant predictors. These findings highlight potential early indicators of treatment engagement that could be targeted to reduce dropout and perhaps facilitate further therapeutic change.

An Item Response Theory Analysis of the Clinician-Administered PTSD Scale for DSM-5 Among Veterans.

We used item response theory (IRT) analysis to examine Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) item performance using data from three large samples of veterans (total N = 808) using both binary and ordinal rating methods. Relative to binary ratings, ordinal ratings provided good coverage from well below to well above average within each symptom cluster. However, coverage varied by cluster, and item difficulties were unevenly distributed within each cluster, with numerous instances of redundancy. For both binary and ordinal scores, flashbacks, dissociative amnesia, and self-destructive behavior items showed a pattern of high difficulty but relatively poor discrimination. Results indicate that CAPS-5 ordinal ratings provide good severity coverage and that most items accurately differentiated between participants by severity. Observed uneven distribution and redundancy in item difficulty suggest there is opportunity to create an abbreviated version of the CAPS-5 for determining PTSD symptom severity, but not DSM-5 PTSD diagnosis, without sacrificing precision.

Benchmarking secondary outcomes to posttraumatic stress disorder symptom change in response to cognitive processing and written exposure therapy for posttraumatic stress disorder.

Posttraumatic stress disorder (PTSD) has high comorbidity with other psychiatric conditions, including depression, generalized anxiety, and suicidality. Evidence-based treatments (EBTs) for PTSD are effective at reducing PTSD symptoms. However, evidence on the impact of PTSD EBTs on comorbid conditions is mixed and often uses pre-post analyses, which disregards PTSD symptom response. This study replicated and extended prior work on benchmarking quality of life to PTSD symptom response to a broader range of secondary outcomes using a research-based metric of clinically meaningful PTSD symptom change. Ninety-five active duty military members seeking treatment for PTSD participated in a randomized noninferiority trial examining two cognitive behavioral therapies for PTSD: Written Exposure Therapy and Cognitive Processing Therapy. Participants completed clinician-administered and self-rating assessments at baseline and 10 weeks post-first treatment session and were classified as PTSD treatment responders or nonresponders. Data were analyzed using generalized linear mixed effects models with repeated measures with fixed effects of time and PTSD symptom response category. PTSD treatment responders experienced significant improvements in secondary outcomes; nonresponders demonstrated statistically significant, but not clinically meaningful, comorbid symptom change. Our findings provide evidence that successfully treating PTSD symptoms may also positively impact psychiatric comorbidity.

Written Exposure Therapy vs Prolonged Exposure Therapy in the Treatment of Posttraumatic Stress Disorder: A Randomized Clinical Trial.

Importance: Evidence-based treatments for posttraumatic stress disorder (PTSD) exist, but all require 8 to 15 sessions and thus are less likely to be completed than brief treatments. Written exposure therapy (WET) is a brief and efficacious treatment that has not been directly compared with prolonged exposure therapy (PE), a more time-intensive, exposure-based treatment. Objective: To determine whether WET is noninferior to PE in treating PTSD among veterans. Design, Setting, and Participants: A randomized noninferiority clinical trial was conducted between September 9, 2019, and April 30, 2022. Participants were 178 veterans with PTSD presenting to 1 of 3 Veterans Affairs medical centers. Inclusion criteria consisted of a primary diagnosis of PTSD and stable medication. Exclusion criteria included current psychotherapy for PTSD, high suicide risk, active psychosis, unstable bipolar disorder, and severe cognitive impairment. Independent evaluations were conducted at baseline and 10, 20, and 30 weeks after the first treatment session. Data were analyzed from January 1 to March 31, 2023. Interventions: Participants assigned to WET (n = 88) received five to seven 45- to 60-minute sessions. Participants assigned to PE (n = 90) received eight to fifteen 90-minute sessions. The WET sessions included 30 minutes of writing-based imaginal exposure conducted in session, whereas PE sessions included 40 minutes of in-session imaginal exposure and between-session in vivo exposures. Main Outcomes and Measures: The primary outcome was change in PTSD symptom severity measured with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) from baseline to the 20-week assessment; noninferiority was defined as a less than 10-point difference between the 2 treatment groups. Difference in treatment dropout was also examined. Results: Of the 178 participants, 134 (75.3%) were men, and the mean (SD) age was 44.97 (13.66) years. In terms of race, 37 participants (20.8%) were Black, 112 (62.9%) were White, 11 (6.2%) were more than 1 race, and 18 (10.1%) were of other race (including American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander [some participants did not specify their race when selecting the category "other"]); in terms of ethnicity, 19 participants (10.7%) were Hispanic. Changes in PTSD symptom severity from baseline to all subsequent assessments among individuals randomized to WET were noninferior relative to individuals randomized to PE. The largest difference between treatments was observed at 10 weeks and was in favor of WET (mean difference, 2.42 [95% CI, 0.35-1.46] points). Participants were significantly less likely to drop out of WET compared with PE (11 [12.5%] vs 32 [35.6%]; χ2 = 12.91; Cramer V = 0.27). Conclusions and Relevance: In this study, WET was noninferior to PE in PTSD symptom change and was associated with significantly less attrition. Findings suggest that WET may transcend previously observed barriers to PTSD treatment for both patients and clinicians. Trial Registration: ClinicalTrials.gov Identifier: NCT03962504.

DSM-5 criterion-a-based trauma types in service members and veterans seeking treatment for posttraumatic stress disorder.

OBJECTIVE: In posttraumatic stress disorder (PTSD), the assumption of the equipotentiality of traumas ignores potentially unique contexts and consequences of different traumas. Accordingly, Stein et al. (2012) developed a reliable typing scheme in which assessors categorized descriptions of traumatic events into six "types": life threat to self (LTS), life threat to other, aftermath of violence (AV), traumatic loss, moral injury by self (MIS), and moral injury by other (MIO). We extended this research by validating the typing scheme using participant endorsements of type, rather than assesor-based types. We examined the concordance of participant and assesor types, frequency, and validity of participant-based trauma types by examining associations with baseline mental and behavioral health problems. METHOD: Interviewers enrolled military personnel and veterans (N = 1,443) in clinical trials of PTSD and helped them select the most currently distressing Criterion-A trauma. Participants and, archivally, assessors typed the distressing aspect(s) of this experience. RESULTS: AV was the most frequently participant-endorsed type, but LTS was the most frequently rated worst part of an event. Although participants endorsed MIS and MIO the least frequently, these were associated with worse mental and behavioral health problems. The agreement between participants and assessors regarding the worst part of the event was poor. CONCLUSION: Because of discrepancies between participant and assessor typologies, clinical researchers should use participants' ratings, and these should trump assessor judgment. Differences in pretreatment behavioral and mental health problems across some participant-endorsed trauma types partially support the validity of the participant ratings.

Treatment length and symptom improvement in prolonged exposure and present-centered therapy for posttraumatic stress disorder: Comparing dose-response and good-enough level models in two manualized interventions.

OBJECTIVE: The dose-response model of change in psychotherapy posits that each session of therapy is incrementally beneficial across patients. The contrasting good-enough level model suggests that patients improve at different rates in therapy and discontinue treatment when they are satisfied with their improvement. Support for each theory has been mixed, and many prior studies have relied on samples of patients receiving unstructured treatment approaches. We conducted this study to compare these two theories across two manualized treatments for posttraumatic stress disorder (PTSD). METHOD: Two hundred eighty-four female veterans and military service members with PTSD (Mage = 44.79; 54.6% White non-Hispanic, 6.7% Black non-Hispanic, 37% other) were randomized to receive 10 sessions of prolonged exposure (PE), a trauma-focused therapy, or present-centered therapy (PCT), a non-trauma-focused therapy. Participants completed the PTSD Checklist (PCL) at even-numbered treatment sessions, and the timing of dropout/treatment completion was monitored. RESULTS: The point of highest risk for dropout differed between the treatments, with risk in PE corresponding to the beginning of imaginal exposures. In the PE condition, but not in PCT, a higher number of sessions completed increased the likelihood of achieving reliable clinically significant improvement. Across treatments, the rate of change in PTSD symptoms did not differ according to the number of sessions completed (b = 0.06, p = .687). CONCLUSIONS: Findings support the dose-response model of change in psychotherapy. There were notable differences in dropout across the treatment conditions, including rates, timing, and implications for outcomes. These differences likely reflect differences in content between the protocols. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

A systematic review of literature examining mediators and mechanisms of change in empirically supported treatments for posttraumatic stress disorder.

Despite the availability of empirically supported treatments (ESTs) for posttraumatic stress disorder (PTSD), relatively little is known regarding these treatments' mechanisms of change. This systematic review moves beyond previous reviews by summarizing the findings and reviewing the methodological quality of literature that specifically examined mediators/mechanisms of change in ESTs for PTSD. Studies were included if they were written in English, empirical, peer-reviewed, claimed to study mediators/mechanisms of a recommended PTSD treatment, measured the mediator/mechanism during or before and after treatment, and included a posttreatment PTSD or global outcome (e.g., functioning). PsycINFO and PubMed were searched on October 7, 2022. Two coders screened and coded studies. Sixty-two eligible studies were identified. The most consistent mediator/mechanism was reduction in negative posttraumatic cognitions, followed by between-session extinction and decreased depression. Only 47% of studies measured the mediator/mechanism before the outcome and measured the mediator/mechanism and outcome at least three times, and 32% also used growth curve modeling to establish temporal precedence of change in the mediator/mechanism and outcome. Many of the mediators/mechanisms examined had weak or no empirical support. Results highlight the need for improved methodological rigor in treatment mediator and mechanism research. Implications for clinical care and research are discussed. PROSPERO ID: 248088.

Written exposure therapy for treatment of perinatal PTSD among women with comorbid PTSD and SUD: A pilot study examining feasibility, acceptability, and preliminary effectiveness.

OBJECTIVE: This pilot open trial examined the feasibility, acceptability, and preliminary effectiveness of Written Exposure Therapy (WET), a 5-session evidence-based intervention for posttraumatic stress disorder (PTSD) during pregnancy. Participants were pregnant women with comorbid PTSD and substance use disorder (SUD) receiving prenatal care in a high risk obstetrics-addictions clinic. METHODS: A total of 18 participants with probable PTSD engaged in the intervention, and 10 completed the intervention and were included in outcome analyses. Wilcoxon's Signed-Rank analyses were used to evaluate PTSD and depression symptoms and craving at pre-intervention to post-intervention and pre-intervention to the 6-month postpartum follow-up. Engagement and retention in WET and therapist fidelity to the intervention manual were used to assess feasibility. Quantitative and qualitative measures of patient satisfaction were used to assess acceptability. RESULTS: PTSD symptoms significantly decreased from pre-intervention to post-intervention (S = 26.6, p = 0.006), which sustained at the 6-month postpartum follow-up (S = 10.5, p = 0.031). Participant satisfaction at post-intervention was high. Therapists demonstrated high adherence to the intervention and excellent competence. CONCLUSIONS: WET was a feasible and acceptable treatment for PTSD in this sample. Randomized clinical trial studies with a general group of pregnant women are needed to expand upon these findings and perform a full-scale test of effectiveness of this intervention.

Using Client Narratives to Identify Predictors of Outcome in Written Exposure Therapy and Cognitive Processing Therapy.

Written exposure therapy (WET) is a brief, five-session treatment for posttraumatic stress disorder (PTSD) that aims to improve access to care. WET has been demonstrated to be an efficacious PTSD treatment with lower rates of dropout and noninferior PTSD symptom outcome compared to cognitive processing therapy (CPT), a 12-session, gold-standard treatment. To identify predictors of treatment outcome in both WET and CPT, the current study examined the content of participants' written narratives. Participants were 123 adults with PTSD who were randomly assigned to receive WET (n = 61) or CPT (n = 62). The Change and Growth Experiences Scale (CHANGE) coding system was used to code all available narratives in both treatment conditions for variables hypothesized to be relevant to therapeutic change. Linear regression analyses revealed that in WET, higher average levels of accommodated (healthy, balanced) beliefs and an increase in accommodated beliefs from the first to the final impact statement predicted better PTSD symptom outcome at 12 weeks postrandomization. In CPT, higher average levels of overgeneralized and accommodated beliefs and lower levels of avoidance expressed in the narratives predicted better PTSD outcome. There were no significant predictors of outcome in analyses of change from the first to final impact statement in CPT. These findings add to research identifying predictors of change in WET and CPT by highlighting the importance of low avoidance in CPT and of trauma-related cognitions in both CPT and WET, even though WET is a brief written intervention that does not explicitly target cognitive change.

Predictors of treatment completion in group psychotherapy for male veterans with posttraumatic stress disorder.

Group therapy is a frequently used therapy format for posttraumatic stress disorder (PTSD). However, factors contributing to treatment completion remain understudied. The current study examined predictors of treatment completion, defined as having completed 10 out of 14 sessions within 16 weeks, in veterans with PTSD who engaged in a hybrid efficacy-effectiveness randomized controlled trial of group psychotherapy for PTSD. Veterans (N = 198) were randomly assigned to 14 sessions of either group cognitive behavioral treatment (GBCT; n = 98) or group present-centered treatment (GPCT; n = 100). Four primary domains of predictors were examined, encompassing sociodemographic factors, the severity of PTSD and comorbid conditions, modifiable predictors, and treatment condition. Multilevel binomial logistic regression models following the Fournier analysis approach were used to examine significant predictors within domains, which were then included in a final model. Overall, 70.7% of participants completed treatment (GCBT = 61.6%, GPCT = 79.8%). Participants in the GPCT condition were 2.389 times, 95% CI [1.394, 4.092], more likely to complete treatment than those in the GCBT condition. Older age, a higher income and level of educational attainment, more lifetime and current mental health diagnoses, and higher use of positive reappraisal ER skills predicted treatment completion. Higher levels of depressive symptoms, cumulative trauma burden, and use of positive refocusing ER skills predicted treatment noncompletion. These findings are discussed in the context of current clinical and research practices for examining treatment noncompletion, with attention to the inclusion of translational predictors.

Psychometric Properties of the Self-Injurious Thoughts and Behaviors Interview-Short Form Among U.S. Active Duty Military Service Members and Veterans.

We assessed the interrater reliability, convergent validity, and discriminant validity of the Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF) in a sample of 1,944 active duty service members and veterans seeking services for posttraumatic stress disorder (PTSD) and related conditions. The SITBI-SF demonstrated high interrater reliability and good convergent and discriminant validity. The measurement properties of the SITBI-SF were comparable across service members and veterans. Approximately 8% of participants who denied a history of suicidal ideation on the SITBI-SF reported suicidal ideation on a separate self-report questionnaire (i.e., discordant responders). Discordant responders reported significantly higher levels of PTSD symptoms than those who denied suicidal ideation on both response formats. Findings suggest that the SITBI-SF is a reliable and valid interview-based measure of suicide-related thoughts and behaviors for use with military service members and veterans. Suicide risk assessment might be optimized if the SITBI-SF interview is combined with a self-report measure of related constructs.

Effectiveness of written exposure therapy for posttraumatic stress disorder in the Department of Veterans Affairs Healthcare System.

OBJECTIVE: Written Exposure Therapy (WET) for posttraumatic stress disorder (PTSD) has been shown to be efficacious in clinical trials; however, research is needed to determine WET's effectiveness in clinical practice settings. Additionally, research is needed to understand whether patient characteristics or treatment delivery format moderate outcomes. METHOD: Patient outcomes (n = 277) were assessed as part of a multisite training and implementation program in the Department of Veterans Affairs (VA). During treatment, patients completed self-report measures of PTSD, depression, and functional impairment. Patient characteristics (i.e., demographics, psychiatric comorbidity, trauma type) and treatment delivery format (i.e., telehealth vs. in-person) were assessed as treatment moderators. RESULTS: Intent-to-treat analyses indicated that WET was effective in reducing PTSD symptoms (d = .84), depression symptoms (d = .47), and functional impairment (d = .36) during treatment. Approximately one quarter of patients dropped out of treatment prematurely. No moderators of PTSD treatment outcome were observed; however, telehealth delivery was associated with lower dropout. CONCLUSIONS: WET was an effective approach across a range of patient characteristics in this sample of veterans with PTSD. WET was also effective whether delivered in-person or via telehealth. WET is a promising treatment option for veteran patients in VA clinical care settings. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Delivery of written exposure therapy for PTSD in a university counseling center.

Posttraumatic stress disorder (PTSD) occurs at high rates among college students, and there is an urgent need to develop brief and accessible interventions to help these at-risk students achieve academic and career success. This open-trial pilot study tested the feasibility and effectiveness of Written Exposure Therapy (WET; Sloan & Marx, 2019), a brief, five-session exposure-based treatment, when delivered in a real-world Counseling Services Center. Students who met criteria for probable PTSD were assessed at baseline, posttreatment, and 3-month follow-up using self-report assessments of PTSD and depression. Of 28 eligible college students, 22/28 (78.6%) completed at least one treatment session, and of those students, 14/22 (63.6%) completed the full five sessions, 12 of whom completed both the posttreatment assessment and the 3-month follow-up assessment. Data were analyzed using intent-to-treat (N = 22) and per-protocol (n = 12) samples. As hypothesized, in both samples, PTSD symptoms decreased from baseline to posttreatment (η² = .60-.81; very large effects), and these improvements were maintained at the 3-month follow-up. Similar findings were observed with respect to decreases in self-reported depression, but not with respect to decreases in educational impairment or increases in academic self-efficacy. Qualitative data indicated that both students and therapists found the treatment credible and acceptable. These findings offer preliminary support for the utility of WET for PTSD when delivered in a student counseling services center. Suggestions for adapting WET within a student counseling services environment are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

An examination of individual and organizational theory in a pilot virtual facilitated learning collaborative to implement written exposure therapy.

Participant training alone is typically insufficient to ensure adoption of a new treatment. This study provides preliminary data on a pilot program that implemented written exposure therapy (WET) through a virtual facilitated learning collaborative (VFLC) that combined clinician training with implementation support. Ninety-five mental health clinicians from Veterans Health Administration clinics enrolled in the VFLC. Clinicians received 6 hr of training in WET plus weekly group consultation on training cases for 12-16 weeks. Clinic leaders participated in monthly group calls with facilitators to develop and track implementation plans, address barriers, and share resources. Clinicians completed the Perceived Characteristics of Intervention Scale and Implementation Climate Scale before training and after consultation, and the Intention Scale for providers after the program. Clinicians' positive perceptions of WET increased over time, t(85) = -8.80, p < .001, d = 0.95, and changes were moderated by how much reduction in symptoms their patients experienced, t(151) = -2.13, p = .035. The implementation climate for WET also improved over time, t(85) = -3.55, p < .001, d = 0.36. Consistent with the theory of planned behavior, clinicians' intention to continue using WET after training was influenced by their perceptions and attitudes about WET, subjective norms, and perceived behavioral control. The VFLC model was feasible and associated with increases in clinicians' and leaders' support for using WET. Patient outcomes predicted the amount of change in clinicians' perceptions about WET.

The effect of time since index trauma on trauma-related beliefs.

OBJECTIVE: Greater duration of negative trauma-related beliefs may inhibit improvements in these cognitions during posttraumatic stress disorder (PTSD) treatment. The goal of the current study was to examine the impact of time since trauma on change in negative trauma-related beliefs during PTSD treatment. METHOD: A sample of 126 adults diagnosed with PTSD were randomized to Cognitive Processing Therapy (CPT) or Written Exposure Therapy (WET) and completed the Posttraumatic Cognitions Inventory (PTCI) at pretreatment and 6, 12, 24, 36, and 60 weeks following the first treatment session. RESULTS: Consistent with past findings, negative cognitions related to the self, others, and self-blame decreased during and after trauma-focused therapy. Greater time since the trauma was associated with less improvement in negative trauma-related beliefs about the world and less early improvement in negative trauma-related beliefs about the self and self-blame. The effect of time since trauma on reduction in negative trauma-related beliefs about the world was stronger among participants randomized to CPT. CONCLUSIONS: These results indicate that trauma-focused therapies become less potent in reducing trauma-related beliefs as time progresses since trauma exposure, particularly in CPT, for beliefs about the world. Results indicate PTSD treatment should be provided in closer proximity to trauma exposure before negative trauma-related beliefs become inflexible.
