The purpose of the study was to evaluate the immediate impact of two new versions of the Project SPORT program, a brief one-on-one tailored consult addressing alcohol use and physical activity for adolescents. One new version was a brief interactive CD-ROM (Study one) and a second was a brief small group consultation (Study two). In study one, high school students were exposed to either an interactive CD-ROM consultation or a non-interactive computer program. In study two, students either participated in a small group consultation or health booklet control. These studies suggest both interventions were highly acceptable to participants, however, the new CD-ROM version of Project SPORT had a greater positive effective on females than males. Suggestions to make the CD-ROM more acceptable and effective for males are presented. The small group version of Project SPORT was largely acceptable and potentially efficacious for both male and female adolescents, with the largest impact seen on participants' images, beliefs, and commitment related to physical activity.
