groups. The intervention and control groups completed questionnaires at baseline, postintervention, and 1 year after the end of the program. Some 62 percent of the original sample completed the 1-year follow-up questionnaire. Investigators measured a variety of personal factors and attitudes (such as perceived probability of pregnancy occurring, feelings about the seriousness of a pregnancy, etc.) and then related these factors to the outcome measures. Males in the intervention group were significantly more likely to remain abstinent than males in the control group (p < 0.05) at the 1-year follow-up. There did not appear to be a similar program effect on women. Among participants who became sexually active following the program, women in the control group were significantly more likely to have used contraception at last intercourse (p < 0.01). Among participants who were sexually active before the program, all groups showed significantly more contraceptive use at the 1-year follow-up; however, men in the intervention group were significantly more likely to use contraception than men in the control group (p < 0.05). The researchers suggest that the program appeared to have the most positive effect on high-risk young men, but was less useful for young women in general and for young women making the transition to sexual intercourse in particular.
