This study examined the effects of 2 HIV prevention interventions on condom use and mediators of condom use. College students were randomly assigned to a control condition or an intervention (communication skills or technical skills). Those who received either intervention had greater condom use self-efficacy, more positive condom use attitudes, and stronger intentions to use condoms than did controls. Furthermore, 3-month follow-up data revealed that students in either intervention who were not in a steady dating relationship reported more consistent condom use than did those in the control condition, whereas students who were in either intervention and in a relationship reported somewhat less consistent condom use than did those in the control condition. Analyses suggested that effects of the interventions on condom use were mediated by increased intentions to use condoms.
