The ASSESS (Awareness, Skills, Self-efficacy/Self-esteem, and Social Support) program was a randomized intervention trial designed to determine if risk assessment and safe-sex education could reduce sexual intercourse and increase condom use among early adolescents (Boekeloo, Schamus, Simmens, Cheng, O'Connor, and D'Angelo, 1999). Study participants were teens aged 12-15 who visited a primary care physician's office for a general health exam. Teens were asked to participate in the study and, if they agreed, were randomly assigned to either the intervention or control group. Those in the intervention group received comprehensive STD prevention information from their physician that included materials about abstinence as well as condom use. The program aimed to increase awareness of sexual risks and to teach teens skills to help them avoid risky sexual situations. It incorporated face-to-face discussions between the physician and adolescent, as well as written materials about proper condom use, self-efficacy, community resources, and effective parent-child communication. Adolescents in the control group did not receive the educational tools. Statistical analyses revealed that, three months after the intervention, the ASSESS program showed a positive impact on attitudes toward and use of condoms, and on STD knowledge and outcomes. While significant impacts on condom use disappeared by 9 months after the intervention, STD outcomes were still significantly lower among teens in the treatment group. No significant decline in sexual intercourse, frequency of sexual activity, number of sexual partners was observed.
