'The Youth AIDS Prevention Project (YAPP) targeted adolescents in junior high schools in 15 school districts that were considered to be high risk for HIV infection (Levy, Perhats, Weeks, Handler, Zhu & Flay, 1995). School districts received the YAPP intervention or a delayed treatment/control. Students in control school districts continued to receive the same state-required AIDS education that was already in place. Students in the experimental groups received ten 1-hour sessions over a two week period in which active learning and skills-building techniques (e.g., role playing, educational competitions and small group exercises) were used to educate and influence students on HIV/AIDS and pregnancy and STD prevention and decision making skills (Levy et al., 1995). Students in the experimental condition were required to do homework (half of the students were required to complete their assignments with their parents). Originally, the experimental groups were divided into two groups with one group having a parent-interaction component. However, because participation was low, the two groups were combined for comparison purposes. Results indicate that among students who became sexually active between the start of the intervention and the follow-up, students in the experimental group did not differ significantly from students in the control group in frequency of sexual intercourse, number of sexual partners, or use of condoms. However, students in the experimental group were more likely to use condoms with foam than students in the control group.
