Video intervention to increase perceived self-efficacy for condom use in a randomized controlled trial of female adolescents

Study Objective: To assess the effects of the Seventeen Days interactive video on young women’s perceived self-efficacy for using condoms six months after being offered the intervention, relative to a control. Design: Multisite randomized controlled trial. Setting: Twenty participating health clinics and county health departments in Ohio, Pennsylvania, and West Virginia. Participants: Sexually active females ages 14 to 19: Interventions: Seventeen Days (treatment intervention; sex education) versus Driving Skills for Life (control intervention; driving education). Main Outcome Measures: Perceived self-efficacy for condom use. Results and Conclusions: Participants in the Seventeen Days group reported higher perceived condom acquisition self-efficacy after six months than those in the driving group. This finding held after controlling for baseline self-efficacy scores and other covariates. The Seventeen Days program shows promise to improve perceived self-efficacy to acquire condoms among sexually active female adolescents—an important precursor to behavior change.
