Youth AIDS Prevention Project (YAPP)

Originally designed for high-risk youth, including African-Americans, YAPP aims to prevent STDs, HIV/AIDS and substance abuse among high-risk junior high school students. Guiding the program is social cognitive theory, which targets teens' knowledge, attitudes, self-efficacy, intentions and behaviors regarding high-risk activities. The intervention includes ten sessions for 7th grade students, delivered in regularly scheduled health or science classes, and a five-part booster session offered one year later, when the teens have entered 8th grade. Classes cover transmission and prevention of STDs and HIV/AIDS, the importance of using condoms for those who choose to have sex, and the development of decision-making and resistance/negotiation skills. In addition to lectures and class discussions, active learning is emphasized, with opportunities for students to participate in small group exercises and role plays. There are also homework activities and opportunities for parental involvement. A field study of the intervention was conducted in fifteen high-risk school districts in Chicago. Research focused on the group of students who first became sexually active during the study period. Following the booster session, these students were more likely than a control group of peers to report using condoms with foam; they also expressed greater intention to use condoms with foam in the future.


This intervention is most suitable for 7th grade classrooms, with the five session booster program offered in 8th grade classrooms one year later. The intervention could also be used in community-based organizations serving teens between the ages of 12 and 14 years.


Age, Gender
The original sample included 1,459 7th grade students, of whom 48% were male. The booster program for 8th grade students involved 1,001 teens.

58% African-American, 16% Latino, 21% White, 5% other.


During the first year of the program, ten class sessions are offered, one per day over a two week period. A one week, five session booster program should be held one year later.


Ideally the program should be led by a professional, master's level health educator who has received special training in HIVAIDS; one instructor is required per classroom. However, YAPP was designed for regular classroom teachers (with modest training) to deliver YAPP to their classes. The additional training is recommended to familiarize instructors with the YAPP curriculum.
