Using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework to evaluate the written exposure therapy training program in the Veterans Health Administration.

The Veterans Health Administration (VHA) has rolled out evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD); however, reach has remained low, and there is a need for briefer interventions. The National Center for PTSD conducted a facilitated learning collaborative to train clinicians and support VHA PTSD teams in their adoption of an emerging best practice, written exposure therapy (WET). Guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) evaluation framework, the present study utilized longitudinal data from 178 clinicians and 556 patients across seven training cohorts to evaluate key clinical and implementation outcomes and whether clinic (i.e., implementation climate) or clinician factors (i.e., treatment attitudes) were associated with effectiveness and implementation. Intent-to-treat analyses indicated WET was effective in reducing PTSD (
