Trial of Surf and Hike Therapy for Major Depressive Disorder

A Randomized Controlled Trial of Surf and Hike Therapy for Active-duty Service Members With Major Depressive Disorder

This study uses a randomized controlled trial design to compare the psychological effects of surf therapy to hike therapy in active duty service members who have been diagnosed with major depressive disorder.

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.

• Have medical clearance to participate in these programs;
• Have a current diagnosis of Major Depressive Disorder based on DSM-5 criteria.
