The Military tailored RR training program will consist of six weekly small group sessions which involve group presentations, in-group skill building exercises, and at-home assignments. Groups will contain 5-8 participants who are active-duty Soldiers enrolled in either Respect-MIL or the Interdisciplinary Pain Management Center (IPMC).

Participants randomized to the control group will receive standard care through their providers at Respect-MIL or at the IPMC. Participants randomized to the control group will remain on the wait list for further standard care. After the collection of the final data point, these participants will also have the option to participate in an abbreviated, two-hour version of the RR training.

Behavioral Relaxation Response Training (Benson-Henry Institute Relaxation Response Training) Participants randomized to the intervention group will participate in the six weekly RR sessions. Examples of in-group skill building exercises are mini relaxations, diaphragmatic breathing, introduction to imagery, and eliciting RR through Yoga. Presentations topics include Introduction to Mind/Body Medicine, Introduction to the RR, Experiential RR Sessions, and Introduction to Cognitive Restructuring. Home skill building assignments include relaxation focus practice, an appreciation journal, self-monitoring with Biodots (biosensor technology that helps participants to monitor and regulate their psycho-emotional state), physical activity, balanced nutrition, and progress notes.

Sleep will be measured pre and post intervention. Sleep will be measured by the Pittsburgh Sleep Quality Index (PSQI). The PSQI assesses sleep quality and disturbances during the past month based on seven component scores for sleep quality, latency, duration, efficiency, disturbance, medication use, and daytime dysfunction that sum to a global score. A Sleep Diary will also be used to measure sleep and related factors.
