Recent advances in research on school-based extracurricular activities and adolescent development

► We review the last 5 years of literature extracurricular activity participation. ► We examine the links between participation and adolescent developmental outcomes. ► We focus on recent advances in participation measurement, mediators and moderators. ► Use of longitudinal data and sophisticated participation measures has increased. ► These new studies demonstrate a more complicated picture of participation and development. Updating a previous systematic review of the literature, this review summarizes the literature over the last 5 years on the relationship between school-based extracurricular activity participation and academic achievement, substance use, sexual activity, psychological adjustment, and delinquency. The review also considers mediators and moderators of these relationships. This review also discusses recent advances in activity research including participation measurement (intensity, breadth, and duration), person-centered approaches, and an exploration of the overscheduling hypothesis. The review reveals a mixed picture of the relationship between activity participation and these adolescent developmental outcomes. A call for continued exploration into measurement issues, analysis approaches, outcome measures, and causal models of activities and adolescent functioning is made.
