Abstract:

Prolonged exposure (PE) is a first-line treatment for posttraumatic stress disorder (PTSD) available in specialty mental health. PE for primary care (PE-PC) is a brief version of PE adapted for primary care mental health integration, composed of four-eight, 30-min sessions. Using retrospective data of PE-PC training cases from 155 Veterans Health Administration (VHA) providers in 99 VHA clinics who participated in a 4- to 6-month PE-PC training and consultation program, we examined patients' PTSD and depression severity across sessions via mixed effects multilevel linear modeling. Additionally, hierarchical logistic regression analysis was conducted to assess predictors of treatment dropout. Among 737 veterans, medium-to-large reductions in PTSD (intent-to-treat, Cohen's = 0.63; completers, Cohen's = 0.79) and small-to-medium reductions in depression (intent-to-treat, Cohen's = 0.40; completers, Cohen's = 0.51) were observed. The modal number of PE-PC sessions was five ( = 1.98). Providers previously trained in both PE and cognitive processing therapy (CPT) were more likely than providers who were not trained in either PE or CPT to have veterans complete PE-PC ( = 1.54). Veterans with military sexual trauma were less likely to complete PE-PC than veterans with combat trauma ( = 0.42). Asian American and Pacific Islander veterans were more likely than White veterans to complete treatment ( = 2.93). Older veterans were more likely than younger veterans to complete treatment ( = 1.11). (PsycInfo Database Record (c) 2023 APA, all rights reserved).
