PROJECT SUMMARY Posttraumatic stress disorder (PTSD) results in substantial costs to society is highly prevalent among adults. Importantly, the prevalence PTSD within primary care settings is even higher than the general population as primary care is the setting to which individuals with PTSD most often present. Evidence-based psychotherapies (EBPs) for PTSD are available but dissemination within real world settings is fraught with challenges because these therapies require 10-15, lengthy treatment sessions and extensive therapist training to implement, and these treatments are not feasible within primary care settings given the limited time resources. Consequently, there are multiple barriers to accessing EBPs for PTSD. Efforts to integrate mental health services within primary care for PTSD though collaborative care management (CoCM) interventions are rapidly expanding and have been shown to be effective in the treatment of depression and anxiety. However, the evidence for PTSD is limited due to the time intensive nature of the PTSD therapy approaches that have been examined. An efficient PTSD treatment approach is needed to address the treatment needs of individuals with PTSD presenting to primary care. Written exposure therapy (WET) is a brief EBP that provides an alternative to more intensive EBPs. Recent studies of WET have yielded positive outcomes and have shown it to be non-inferior when directly compared to more time intensive PTSD EBPs, but WET has not yet been examined within the primary care environment. The primary aims of the proposed study are to evaluate the effectiveness and implementation of delivering WET into CoCM to improve the management of PTSD among underserved primary care patients in Federally Qualified Health Centers (FQHCs). The pragmatic cluster- randomized study will use a hybrid effectiveness-implementation design. Twelve FQHCs will be randomized to either CoCM plus WET (CoCM+WET) or CoCM alone and 60 patients within each FQHC will be screened for eligibility. We will use the RE-AIM framework (for Reach, Efficacy/Effectiveness, Adoption, Implementation, & Maintenance) to evaluate the effectiveness and implementation process of the CoCM+WET intervention using mixed methods. To examine effectiveness and potential mediators and moderators of the intervention, we will administer assessments at baseline, 3- and 6-month follow-up. To assess implementation, we will use clinic process data and clinic staff interviews pre- and post-intervention. This study has the potential to substantially impact practice and public health by validating the effectiveness and feasibility of delivering a brief trauma- focused EBP embedded within CoCM in primary care to improve PTSD outcomes for underserved patients.
