Promising Predictors of Adolescent Sexual Behavior Outcomes: A Systematic Review of Longitudinal Research

Abstract

This review examined research to identify longitudinal predictors of adolescent sexual behavior outcomes. These predictors hold promise as potential outcomes for teen pregnancy prevention program evaluations when measuring sexual behavior outcomes is infeasible or theoretically, methodologically, or developmentally inappropriate. We conducted a systematic review using a prespecified search strategy and processes consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We examined 32 research studies published between 2008 and 2024. Four categories of predictors of sexual behavior during adolescence emerged across the reviewed studies. Variables within the caregiver control, self-regulation, sexting, and substance use categories each predict future sexual behavior outcomes, with findings consistent across 3 or more studies for each category. This systematic review documents the current evidence base for precursors of sexual behavior outcomes among adolescents and specifies which predictors have promising, potentially promising, mixed, and limited evidence. This review is the first step in gathering information that will eventually inform an avenue for teen pregnancy prevention program developers and researchers to highlight the promise of programs when evaluating impacts on sexual behavior outcomes is infeasible or inappropriate.
