RESUMO
Prolonged exposure therapy (PE) is an evidence-based psychotherapy (EBP) for posttraumatic stress disorder (PTSD) that is underutilized in the military health system. Previous research suggests that postworkshop consultation is important for successful implementation. However, little is known about how consultation may relate to EBP adoption or patient outcomes. The present study addressed these gaps by examining associations between consultation, provider self-efficacy, use of PE, and patient outcomes using a multistep mediation model. This study used data from Foa et al. (2020), a two-armed randomized implementation trial comparing two PE training models: standard training (workshop only) and extended training (workshop + 6-8 months of postworkshop expert consultation) at three U.S. Army sites. Participants were patients with PTSD (N = 242) receiving care from the participating providers (N = 103). Providers who received extended training reported greater PE self-efficacy compared to standard training providers, but self-efficacy was unrelated to their use of PE components or to patient outcomes. Extended training providers used more PE components and had superior patient outcomes than standard training providers, and patient outcomes were mediated by the use of PE components. To our knowledge, this is the first study to demonstrate that EBP consultation leads to improved clinical outcomes for patients through increased use of the EBP. PE adoption (i.e., use of PE components in therapy) was not explained by increases in self-efficacy among providers who received extended training. Therefore, future research should assess how other factors may influence provider behavior in implementing EBPs. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
RESUMO
BACKGROUND: Prolonged exposure therapy (PE) is an evidence-based treatment for posttraumatic stress disorder (PTSD) that is underutilized in the military health system. Standard workshop training in PE may not be sufficient to alter provider behavior, but post-workshop consultation requires significant resources. Therefore, it is important to determine the incremental utility of post-workshop consultation. METHODS: This study used a hybrid type III randomized implementation trial at 3 US Army installations. Providers were randomized to receive a 4-day prolonged exposure workshop (Standard training condition, n = 60), or the prolonged exposure workshop followed by 6-8 months of post-workshop expert case consultation (Extended training condition, n = 43). The effects training condition were examined on provider attitudes (self-efficacy in delivering PE, expectations for patient improvement, and beliefs about PE), use of PE and PE components, and clinical outcomes of patients with PTSD (using the Clinician-Administered PTSD Scale (CAPS-5)). RESULTS: Extended condition providers reported greater improvements in self-efficacy, b = .83, 95% CI [.38, 1.27], t(79) = 3.71, p = .001, and d = .63. A greater proportion of patients in the Extended condition (44%) than in the Standard condition (27%) received at least 1 PE session, b = .76, t(233) = 2.53, p = .012, and OR = 2.13. Extended condition providers used more PE components (M = .9/session) than did Standard condition providers (M = .5/session), b = .54, 95% CI [.15, .93], t(68) = 2.70, p = .007, and d = .68. Finally, decrease in patients' PTSD symptoms was faster for patients of Extended condition providers than for patients of Standard condition providers, b = - 1.81, 95% CI [- 3.57, - .04], t(263) = - 2.02, p = .045, and d = .66, and their symptoms were lower at the second assessment, b = - 5.47, 95% CI [- 9.30, - 1.63], t(210) = - 2.81, p = .005, and d = .66. CONCLUSIONS: Post-workshop consultation improved self-efficacy for delivering PE, greater use of PE, faster PTSD reduction, and lower PTSD severity at the second assessment. To our knowledge, this is the first demonstration that post-workshop case consultation for PE improves patient outcomes. TRIAL REGISTRATION: Clinicaltrials.gov , NCT02982538 .

This randomized trial examines the dissemination and implementation of prolonged exposure (PE) therapy for posttraumatic stress symptoms in U.S. Army medical treatment facilities. The study compares two PE training models: Standard PE training, comprised of a 4-day workshop only, and Extended PE training, comprised of a 4-day workshop plus expert case consultation. Behavioral health providers (N=180) across three medium-to-large Army installations will be randomly assigned to either Standard PE training or Extended PE training. Changes in provider attitudes will be examined across groups. After completing PE training, the use of PE components with patients reporting posttraumatic stress symptoms and clinical outcomes of these participating patients (N=500) will be examined. This article describes the rationale and methods of the study. In addition, a number of methodological issues in conducting a multisite naturalistic study in the U.S. Army are discussed.

Heavy alcohol use in college students is a serious health risk. It is unclear how cultural variables impact alcohol use in Hispanic college populations. Here, the relationships between gender, bicultural identity, familism, and adherence to traditional gender roles with heavy episodic drinking (HED) in a Hispanic college sample are assessed. Participants, 80 males and 80 females, were asked to complete a questionnaire packet, which assessed demographic information, as well as measures designed to rate drinking amount and frequency, bicultural integration, familism, and traditional gender role adherence. Average age of the sample was 19.9 years (SD = 3.05), in which the majority of participants were classified as either Freshmen or Sophomores (88.8%). Overall, 47.5% of participants reported engaging in HED, with 51% of men and 44% of women reporting HED. Univariate analyses along with logistic regression were utilized to assess possible differences and correlates of HED. Neither individual predictors nor the overall model were statistically significant. These findings suggest the need for continued assessment of HED in Hispanic college students using other culturally based constructs, as well as psychosocial factors that are found to predict heavy drinking in other ethnocultural college-aged students.
