Open Trial of Behavioral Activation and Social Engagement (BASE) for Posttraumatic Stress Disorder (PTSD)

Participants will be asked to attend 6 in-person or phone-mediated therapy sessions lasting approximately 45 minutes per session, to be held in Primary Care settings. Content of therapy sessions includes education about PTSD symptoms, discussion of the role of avoidance in maintaining PTSD symptoms, self-monitoring homework to identify links between activity level and emotions, and homework designed to increase engagement in valued activities, with a focus on increasing social contact and support. If relevant, participants will be instructed in basic communication skills, social skills, and relaxation skills.
