This study analyze type and effectiveness of adolescents’ community development programs reduce multiple health risk behaviors among adolescents. Methods: This scoping review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). With a date range of 2015–2021, searches were conducted in PubMed, EBSCO, and ProQuest using keywords (((Life skill education) OR (community development)) AND ((health risk behavior) OR (risk behavior)) AND ((adolescent) OR (adolescence) OR (teenagers) OR (teens) OR (youth))). After title and abstract checking, full-text retrieval, and data extraction, data were synthesized based on the main objectives. The most important data were tabulated. Results: Most studies showed that community development–based interventions effectively reduce adolescents’ health risk behaviors, including risky sexual behaviors, drug and alcohol use. Interventions were carried out in schools, places of worship, and communities, involving adolescents, educational institutions, health professionals, religious leaders, and families. Conclusion: This review can assist community health nurses, policymakers, researchers, and teachers in developing and implementing effective community-development programs that ensure knowledge, attitudes, and skills transfer to reduce health risk behaviors.
