About this study

Official title: 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.

Read the 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.

Study groupRoleWhat they receive
Surf TherapyExperimentalParticipants 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Montgomery-Asberg Depression Rating Scale (MADRS)

    The MADRS is a widely used, semi-structured, clinical-interview assessment of depression symptom severity that is intended to be sensitive to change following an intervention.

    Measured: 5 months

Secondary outcomes (6)
  1. PTSD Checklist (PCL-5)

    The PCL-5 is a self-report instrument assessing PTSD symptom severity.

    Measured: 5 months

  2. Generalized Anxiety Disorder (GAD-7)

    The GAD-7 is a self-report instrument that assesses the presence and severity of generalized anxiety disorder.

    Measured: 5 months

  3. Short Form Health Survey - 36 Item, Version 2 (SF-36)

    The SF-36 is a widely used questionnaire that assesses functioning physical and mental health based on eight summary measures.

    Measured: 5 months

  4. Positive and Negative Affect scales (PANAS)

    PANAS is a self-report instrument that measures the extent of 20 feelings and emotions experienced within the past few hours.

    Measured: 5 months

  5. Insomnia Severity Index (ISI)

    The ISI is a 7-item self-report measure that assesses the nature, severity, and impact of insomnia.

    Measured: 5 months
