Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Consenting active duty service members with major depressive disorder will be randomized to receive 6 weeks of either surf or hike therapy. Participants will be allowed to receive the other intervention (i.e., the condition that they were not originally randomized to) if interested after the initial intervention period.

Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors

The assessor will be blinded to participants' intervention condition.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Physical Activity-based Interventions

Intervention Type BEHAVIORAL

Participants will be randomized to one of two physical activity-based interventions, surf or hike therapy.

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.

Group Type ACTIVE_COMPARATOR

Physical Activity-based Interventions

Intervention Type BEHAVIORAL

Participants will be randomized to one of two physical activity-based interventions, surf or hike therapy.
