Mindfulness Based Stress Reduction
Mindfulness Based Stress Reduction (MBSR) is a group-based intervention in which participants are taught different mindfulness meditation practices, including body scan (focusing attention to different areas of the body in sequence), sitting meditation (focusing attention to one's breathing), and Hatha yoga postures (focusing attention to different body sensations during gentle stretching). Participants also are taught how to practice mindfulness while engaging in ordinary activities including walking, standing, and eating. MBSR consists of 8, two-hour weekly sessions and will be delivered in group format. MBSR groups will be delivered virtually.

Trauma Recovery Education Class
Trauma Recovery Education Class (TREC): TREC is a group based treatment that focuses on providing information on PTSD and traumatic reactions. TREC provides psycho-education to Veterans on PTSD, including common reactions to trauma and the role of avoidance, common problems associated with PTSD, as well as common barriers to care (e.g., stigma, maladaptive beliefs, fear). Additional content focuses on problem identification and goal setting, discussion of current problems and life issues, and treatment planning. TREC consists of 8, one-hour weekly sessions.
