In Phase 1, we will enroll 10 participants at each recruitment site (n=20). The purpose of Phase 1 (MOST Preparation Phase) is to allow us to establish and refine procedures at these new sites and document aspects of feasibility, including our ability to a) recruit participants; b) train yoga teachers to fidelity; c) randomize participants to intervention components and correctly administer these components; d) run classes; and e) collect follow-up assessments. Enrollment period for this phase will last approximately 4 months.
