Teen Talk was a sexuality education program given to 13- to 19-year-olds that provided factual information and three different types of group discussions (values, feelings and emotions, and decision-making and personal responsibility) (Eisen, Zellman & McAlister, 1990). Trained staff led adolescents in the experimental group in 8-12 hours of sessions consisting of lectures, simulations, discussions and role-playing (Eisen et al., 1990). The control group received the regularly scheduled sexuality education curriculum. Findings from an experimental evaluation of the program indicate that results were mixed. Males who were virgins at the beginning of the program who participated in the experimental program were more likely to remain virgins in the next year than virgin males in the control group. Further, after controlling for pre-intervention contraceptive efficiency, males who participated in the experimental group were more likely to have greater contraceptive efficiency during the next year than males who were in the control group. There were no significant differences among females in the experimental and control groups in the percentage who remained abstinent or had greater contraceptive efficiency the following year. However, among females who initiated first sexual intercourse after the program started, those in the experimental group were less likely to use an effective contraceptive method at last intercourse and less likely to use effective contraceptive methods in general than those in the control group.
