What this trial studies

This randomized controlled trial will enroll 100 adults with DSM-5 major depressive disorder and randomize them to eight weekly CBT sessions preceded either by moderate aerobic exercise ('ActiveCBT') or by quiet rest watching a nature documentary ('CalmCBT'). Primary outcomes are participant-rated working alliance and change in behavioral activation averaged across the eight sessions, with post-intervention Hamilton Depression Rating Scale scores as a secondary outcome. Suicide risk will be monitored with the Columbia-Suicide Severity Rating Scale for safety, and eligibility requires being CBT‑naïve and medically cleared for exercise. The trial tests whether intentional sequencing of exercise immediately before therapy increases engagement with CBT targets and yields larger symptom reductions than rest before therapy.

Who should consider this trial

Good fit: Adults with DSM‑5 major depressive disorder who have at least mild symptoms (GRID‑HAMD ≥8), are CBT‑naïve, medically able to perform moderate aerobic exercise, and are either not receiving other mental health treatment or are on a stable regimen for at least 8 weeks.

Not a fit: People who are pregnant, nursing, planning pregnancy, have medical contraindications to exercise, or have previously completed structured CBT are excluded and thus would not be expected to benefit from this specific protocol.

Why it matters

Potential benefit: If successful, adding brief aerobic exercise before CBT could strengthen the therapeutic relationship and behavioral activation, making CBT more effective or faster at reducing depressive symptoms.

How similar studies have performed: Exercise alone has established antidepressant effects, but the specific approach of priming CBT with immediate pre-session aerobic exercise is relatively novel and has limited prior randomized trial evidence.
