This six-session program for high school students is delivered by regular classroom teachers. Combining principles of the health belief model with social psychology, the curriculum aims to improve students' knowledge, beliefs, self-efficacy, and risk behaviors concerning HIV/AIDS. The first two classes provide general information about the transmission and prevention of HIV/AIDS and teach students how to appraise their own risk behaviors. During the next two sessions, myths about peers' sexual behaviors are corrected, values clarification is introduced, and students use role play and negotiation skills to practice delaying sexual intercourse. The final lessons involve discussions of purchasing and using condoms. A field study of the program was conducted with a predominantly African-American and Hispanic sample of students attending four New York City public high schools. Compared with a comparison group of peers, program participants scored significantly higher on measures of knowledge, beliefs about the benefits of risk reduction, and beliefs about one's own ability to effect positive change (e.g., self-efficacy). At the three-month follow-up assessment, the program was found to be particularly effective in reducing sexually active participants' number of total sex partners and number of sex acts with high-risk partners, and in increasing the use of condoms.
