Clinical Report: Efficacy and Safety of Exergaming for Depression
Overview
This systematic review and meta-analysis of 58 controlled trials involving 3614 participants found that exergaming interventions significantly reduce depressive symptoms with a moderate effect size. Exergaming demonstrated high adherence, a favorable safety profile, and reasonable cost-effectiveness, particularly when conducted more than three times per week and compared to no intervention or usual care.
Background
Depression affects approximately 350 million people worldwide and is a leading cause of disability. Traditional treatments include pharmacotherapy and psychotherapy, but novel interventions such as exergaming—which combines physical exercise with interactive video gaming—have emerged as potential therapeutic options. Prior evidence on exergaming's effectiveness for depression has been inconsistent, necessitating comprehensive evaluation. This review aimed to assess the efficacy, safety, acceptability, adherence, and cost-effectiveness of exergaming for depressive symptoms.

Key Findings
Exergaming significantly reduces depressive symptoms with a moderate effect size (g = −0.40).
Intervention frequency moderates efficacy; sessions more than three times per week yield larger benefits.
Greater symptom improvement observed when compared to no intervention or usual care controls.
Older adults (≥60 years) show a trend toward enhanced response to exergaming.
High adherence rates indicate good acceptability among participants.
Exergaming interventions have a favorable safety profile and reasonable cost-effectiveness.
Clinical Implications
Exergaming represents a promising adjunct or alternative intervention for patients with depression, especially for those who may benefit from engaging, physical activity-based therapies. Clinicians should consider recommending exergaming programs with a frequency exceeding three sessions per week to optimize therapeutic outcomes. Given its safety and acceptability, exergaming could be integrated into treatment plans, particularly for older adults or those with barriers to traditional exercise.
Conclusion
Exergaming is an effective, safe, and acceptable intervention that moderately reduces depressive symptoms, with enhanced benefits at higher frequencies and in older populations. Further large-scale randomized trials with long-term follow-up are warranted to confirm these findings and assess sustainability.
