Five- and six-year follow-up results from four seventh-grade smoking prevention strategies.

Seven thousand one hundred twenty-four members of the Classes of 1985 and 1986 who had participated as seventh graders in one of several smoking prevention programs were tracked and surveyed for smoking habits at 5- and 6-year follow-up: participation exceeded 90% in both cohorts. These data indicated that participants who received seventh-grade interventions based on the social influences model had similar smoking patterns compared to participants in other conditions. This finding supports the call for booster sessions after the initial seventh-grade intervention program. Future follow-up studies will assess whether the earlier benefits associated with the social influences model will translate into measurable differences in adult smoking patterns.
