Abstract

Background: Project EX is a classroom-based smoking prevention and cessation intervention program that has been well evaluated and designed for assessing the prevention and cessation effects among adolescents in Spain. However, its long-term efficacy is still unknown. This study deals with the outcomes of a 2-year follow-up evaluation of Project EX.

Methods: The intervention was tested using a clustered randomized controlled trial involving 1,546 Spanish students from 3 program schools and 3 control schools. At the end of the 2-year follow-up period, 722 subjects had completed the questionnaires (266 in the control condition and 456 in the program condition) administered to them.

Results: Compared to the control condition, the program condition revealed a greater reduction in nicotine dependence (p = 0.04), smoking intention (p = 0.02), and in the number of cigarettes smoked during the previous month (p = 0.03). The CO monitor repeated assessments revealed a significant decrease of ppm levels in the program group (p < 0.001). Intent-to-treat quit rates were 14.28 and 0%, respectively, for the program and control conditions.

Conclusions: This study provides evidence about the long-term effectiveness of the Project EX classroom-based program for smoking prevention and cessation among adolescents in Spain.
