Effectiveness of Prosocial Behavior Interventions: A Meta-Analysis

Abstract

Prosocial behavior is a voluntary act intended to help or benefit another individual or group of individuals [1]. Several studies have shown that prosocial behavior inhibits aggressive behavior. Most intervention programs in psychology focus on reducing dysfunctional behavior, but interventions aimed to promote positive behaviors are not as frequent. The objective of this meta-analysis is to examine the effects of prosocial behavior interventions in promoting prosocial behavior and reducing aggressive behavior. We included studies that implemented a prosocial behavior intervention on children and adolescents, that were carried out inside or outside of the school schedule, and were published in Spanish, English or Portuguese. Moreover, it only included studies that utilized a randomized controlled design. The impact of the interventions in promoting prosocial behavior and reducing aggressive behaviors were assessed. Following a thorough selection of studies to include in this meta-analysis, ten (10) were chosen since they met inclusion criteria determined by the protocol. The results indicate that intervention programs promoting prosocial behavior have a moderate effect while for the prevention of aggressive behaviors have high effectiveness levels. These results would be providing empirical evidence on the usefulness and effectiveness of these programs from a positive viewpoint prone to strengthen positive resources.
