The study was extended for an additional three years to add to the three year, junior high, design a two arm comparison between high schools either receiving or not receiving a school-wide, community, intervention. The new high school intervention responded to both recent evidence of long term decay in junior high program effectiveness, and a trend toward greater high school smoking onset most notably among females. Secondary objectives for this Demonstration and Education research included (a) a test of the hypothesis that higher levels of implementation were associated with better outcomes; (b) preparation for diffusion of a complete set of curriculum, provider training, program implementation, and evaluation methods and materials; and (c) study of the effects of school environment on program effectiveness.
