Integrated Theory-Based Health and Development Interventions for Young People: A Global Scoping Review

Abstract

Background Most health and developmental issues affecting young people are interrelated. However, few interventions address multiple behavioral domains simultaneously or are based on theories that encompass a holistic perspective of youth development. Aim The purpose of this scoping review was to identify and describe the range of theory-based, multibehavioral health interventions aimed at improving two or more of the following behavioral youth outcomes: (1) sexual and reproductive health; (2) education and employment; (3) violence; and (4) substance use. Methods Interventions conducted worldwide and published in English or Spanish between January 2000 and July 2020 were identified using four databases: PubMed, PsycINFO, LILACS, and SciELO. Results A total of 11,084 articles were identified, of which 477 were retrieved and assessed for eligibility. Twenty-three articles (evaluating 21 interventions) ultimately met the inclusion criteria. Most interventions were conducted in the United States and addressed two behavioral domains of interest, although seven interventions incorporated three domains, and one incorporated all four. Substance use was the most common domain (16 interventions) but only in the United States/Canada, followed by sexual and reproductive health (14 interventions). All produced significant improvement in at least one outcome or for at least one subgroup of youth. The most common theoretical foundations were positive youth development and social learning theory. Conclusion Integrated interventions that are theory based and evidence informed can support positive development and empower youth to make healthy decisions. Further efforts are needed to address structural and policy issues that affect young people’s developmental opportunities and health outcomes.
