title: One-Year Effects of Project EX in Spain: A Classroom-Based Smoking Prevention and Cessation Intervention Program.
abstract: BACKGROUND
  Tobacco use prevalence rates are high among Spanish adolescents. Programming to counteract tobacco use is needed.
  
  
  RESULTS
  The current study provides a one-year follow-up outcome evaluation of Project EX, an eight-session classroom-based curriculum. The intervention was tested using a randomized controlled trial with 1,546 Spanish students, involving three program and three control schools. Compared to the control condition, the program condition revealed a greater reduction in nicotine dependence (p < .05) and CO ppm levels (p < .001), and lower consumption of cigarettes at last month (p = .03).
  
  
  CONCLUSIONS
  Long-term outcomes of the Project EX classroom-based program are promising for adolescent prevention and possibly cessation in Spain.
