Efficacy of Adjunctive Exercise for the Behavioral Treatment of Major Depression
Abstract
Major depressive disorder (MDD) is the leading cause of disability in the developed world and is associated with lost productivity, increased health care utilization, and mortality. Several empirically supported treatments, such as antidepressant medication and cognitive behavioral therapy, exist for the treatment of MDD; however, studies have shown that as many as 34% of individuals do not respond to these treatments. Exercise and stretching interventions represent alternative strategies associated with strong effect sizes in past studies. Additionally, exercise has been shown to enhance cognitive functioning, especially attention and memory. This study aims to investigate the effect of a combined aerobic exercise and behavioral activation treatment (BA) for MDD. Behavioral activation treatment involves completing both pleasant and mastery-based activities with the goal of enhancing mood. The current study will recruit 32 MDD patients for an active treatment phase of nine 60-90 minute sessions (6 weekly sessions and 3 biweekly sessions) of either BA plus exercise (BA+EX) or BA plus stretching (BA+STR). The purpose of this study is to identify if adding aerobic exercise to a brief psychosocial treatment can improve mood above and beyond an active control condition.
Conditions: Major Depressive Disorder.
Primary outcome: Montgomery-Asberg Depression Rating Scale (MADRS).
Enrollment: 38 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 38 participants or records.
