Detailed Description
This prospective, longitudinal randomized controlled trial will enroll up to 86 active duty service members with major depressive disorder who are seeking surf or hike therapy as part of their standard medical care. Participants will be randomly assigned to receive 6 weeks of either surf or hike therapy. Assessor-administered and self-report measures will be completed at pre- and post-program, as well as three months following program completion. Participants also will complete brief, self-report assessments before and after each program activity session.

Experimental: Surf Therapy Participants receive a physical activity-based intervention, which in this arm is surf therapy. Each service member is paired with a surf instructor who typically works with them each week for the length of the program. |
Behavioral: Physical Activity-based Interventions
Participants will be randomized to one of two physical activity-based interventions, surf or hike therapy.

Active Comparator: Hike Therapy Participants receive a physical activity-based intervention, which in this arm is hike therapy. During hike therapy, service members may hike together or at a self-selected pace. |
Behavioral: Physical Activity-based Interventions
Participants will be randomized to one of two physical activity-based interventions, surf or hike therapy.
