| Abstract: | There has been a proliferation of school-based substance abuse prevention programs geared toward reducing or delaying the onset of student use of illegal drugs. But the field has shown a general absence of evaluation dealing with the behavior consequences of these practices. This article fills this gap by using the case of the "I'm Special" Program (ISP) targeted for fourth grade students. Using a quasi-experimental design, a comparison is made between the substance using and other problem behavior of students who have been exposed to the ISP and those who have not during their later school years in grades 5 through 12. At the aggregate level, the proportions of current substance users and the incidence of their related problem behavior were significantly lower among the ISP graduates than those who have not been exposed to the program. In particular, there were consistently lower proportions of current substance users among the ISP recipients than the non-recipients in grades 5-7. However, the impact of the ISP seems to diminish significantly in and around ninth grade. During the senior high level, the pattern revealed is almost random. And, in some drug categories, it has been speculated that the ISP students were trying to "catch up" with what they may have missed out on during earlier grade levels. |
