Effectiveness of Adolescent Peer Education Programs on Reducing HIV/STI Risk: An Integrated Review

There is empirical evidence suggesting that peer education is efficacious in changing adolescent sexual risk behaviors; however, it is unclear if there are similarities in outcomes across studies. Thus, the purpose of this review was to synthesize published research on peer-led HIV/STI intervention programs for adolescents in an effort to determine the efficacy of peer education on knowledge, attitudes, normative beliefs, and sexual behavior. Data collection included online searches of published research from Index Medicus (Medline), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Educational Resources Information Center (ERIC), Educational Index, and PsycINFO (including PsycARTICLES) from 2000 to 2016. Twenty-four quantitative and six qualitative studies were included in the review. There appears to be evidence of the effectiveness of adolescent peer-led HIV education programs on knowledge, attitudes, normative beliefs, and self-efficacy. However, the studies reviewed were equivocal on changes in sexual behavior. The findings of the qualitative/process studies demonstrated perceived program efficacy among staff and peer educators. Peer educators and students placed a high value on peer-led programs. Mediators and/or covariates such as culture, gender, sexual experience, and age may impact findings of adolescent peer intervention studies; therefore, these factors need to be considered when implementing and evaluating peer education programs. Peer education should also focus on variables that were gleaned from qualitative studies, such as the role of the community and altruistic roles.
