This research examined the effects of a school-based prevention program designed to reduce tobacco and alcohol use. The program was introduced in 6 middle schools over a period of three years. Similar 4 schools in these same local area served as a comparison group. Program effects were measured on students by a longitudinal study (from 11 to 13 years old). Findings indicated that the effects of the program were limited at the first year. During the first year program students reported higher level of quality of relationships with teachers and lower levels of tobacco and alcohol use than comparison students. Implications of these findings for prevention programs are discussed.
