Music-based intervention to reduce aggressive behavior in children and adolescents: A meta-analysis.

BACKGROUND We aimed to evaluate the effect of music-based intervention on the aggressive behavior in children and adolescents, and made a comparison of music medicine and music therapy. METHODS We searched PubMed (MEDLINE), Ovid-Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) to identify relevant studies. Standardized mean differences (SMDs) were estimated with random-effect model. RESULTS We included 10 studies and found a significant decrease of aggressive behavior (SMD = -0.99; 95% CI = -1.42 to -0.56) and a significant increase of self-control (SMD = 0.56; 95% CI: 0.19 to 0.93) in the music-based intervention group compared with the control group. The aggressive behavior was significantly decreased in the music therapy group compared with the control group (SMD = -1.79; 95% CI = -3.23 to -0.35); while, no difference was observed between music medicine group and control group. Sub-group analyses exhibited a more efficacious in reducing aggressive behavior in the children received ≥2 sessions per week, the children with a mean age > 10 years, the children whose behavior were reported by teachers, and the children with aggressive behavior before intervention. Sensitivity analyses yielded similar results. CONCLUSION Music-based intervention seemed to be more efficacious for reducing aggression and increasing self-control in children and adolescents, especially music therapy.
