This paper summarizes an evaluation of a three-year school-based abstinence education program that was taught in 21 public schools to eighth- and 10th grade students in Southeastern Alabama between 2003 and 2005. The abstinence education curricula utilized with the students were "Choosing the Best" and "Navigator" programs. A 76-item testing instrument, the Abstinence in Motion (AIM) Assessment Survey, was developed to evaluate changes in participants' attitudes prior to and after the intervention. The research design utilized for this study was a pretest-posttest control group design with three schools serving as the control group. Results indicated that age, gender, family structure and socioeconomic status had a significant effect on changes in attitudes towards abstinence. Implications for school counselors are discussed.
