Abstract

Objective: This study evaluated the efficacy of a version of Project EX that was adapted for implementation in the classroom context (Project EX-4). This paper reports the program outcomes based on pretest, six-month, and one-year follow-up surveys.

Methods: An 8 session classroom-based curriculum was tested with a clustered randomized controlled trial that involved a total of 1097 students in 6 program and 6 control alternative high schools. Weekly and monthly smoking was assessed at the three time points. Outcome effects were analyzed with multi-level random coefficients models.

Results: Students in the program condition experienced a greater reduction in weekly smoking and monthly smoking, at 6-and-12-month follow-ups. The net change varied between -5.1% and -7.6%, comparing the program condition to the control condition.

Conclusions: The implementation of Project EX in a classroom setting produced decreases in smoking among students in the program, relative to those in the standard care control condition. It is likely that a classroom-based smoking prevention/cessation program can lead to lower overall smoking prevalence than a cessation program that is implemented in a school-based smoking cessation clinic format.
