Feasibility, Acceptability, and Preliminary Efficacy of a Brief Online Sexual Health Program for Adolescents

This study evaluated the feasibility, acceptability, and preliminary efficacy of a 45-minute interactive, online sexual health program for adolescents, called Health Education and Relationship Training (HEART). The program was originally developed and evaluated among adolescent girls (HEART for Girls); the current project describes and evaluates a new version of the program that was adapted for boys and girls. Participants were 226 high school students (mean age = 16.3; 58% girls; 46% White; 79% heterosexual). Students were randomized to HEART or an attention-matched control and assessed at pre-test and immediate post-test. Overall, the program was feasible to administer in a school setting and youth found the program highly acceptable (83% liked the program, 87% learned new things, and 93% would use program content in the future). At post-test, students who completed HEART demonstrated improvements on every outcome we examined: sexual communication intentions, condom use intentions, HIV/STD knowledge, condom attitudes, condom norms, self-efficacy to practice safer sex, and sexual assertiveness compared to control participants (effect size ds = .23 to 1.27). Interactions by gender and sexual orientation revealed the program was equally acceptable and worked equally well for boys and girls and for heterosexual and sexual minority youth. We propose several avenues to further adapt and tailor HEART given its promise in promoting adolescent sexual health.
