Redeveloping a Digital Sexual Health Intervention for Adolescents to Allow for Broader Dissemination: Implications for HIV and STD Prevention

HIV/STDs and unintended pregnancy persist among adolescents in the United States; thus, effective sexual health interventions that can be broadly disseminated are necessary. Digital health interventions are highly promising because they allow for customization and widespread reach. The current project involved redeveloping and expanding HEART (Health Education and Relationship Training)—a brief, digital sexual health intervention efficacious at improving safer sex knowledge, self-efficacy, and behavior—onto an open-source platform to allow for greater interactivity and accessibility while reducing long-term program costs. The authors describe the process of adapting, reprogramming, and evaluating the new program, which may serve as a guide for investigators seeking to adapt behavioral interventions onto digital platforms. The final product is an open-source intervention that can be easily adapted for new populations. Among 233 adolescents (M age = 15.06; 64% girls), HEART was highly acceptable and generally feasible to administer, with no differences in acceptability by gender or sexual identity.
