Adherence to Physical Activity Interventions in Major Depressive Disorder: A Systematic Review and Meta-Analysis

Participants with MDD demonstrate lower protocol adherence to PA interventions than to interventions without a PA component. This result was based on a paucity of studies. Rates of intervention receipt, retention, and attendance were comparable in PA and non-PA interventions. Studies could benefit from including individuals with greater depressive symptom severity and supervised activity. With replication, findings could improve the design of, and increase adherence to, PA interventions in MDD.
