Pilot clinic study of Project EX for smoking cessation with Spanish adolescents.

INTRODUCTION: Despite efforts to prevent smoking, the prevalence of smoking in Spanish adolescents remains high. So far, there are no evidence-based smoking cessation programs for adolescents in Spain. METHODS: This study describes the evaluation of Project EX, an eight-session school-based clinic smoking cessation program, with Spanish cigarette smokers 13–19years of age, from 9 schools (four program condition schools and five control condition schools). A group-randomized controlled trial was used. There were 211 smokers at baseline (112 program group, and 99 control group). Evaluation involved an immediate pretest and posttest survey (administered five-weeks later) and six-month follow-up (after the immediate posttest). RESULTS: At immediate posttest, Project EX significantly reduced future nicotine dependence scores (mFTQ; p < .001), and increased intention to quit smoking (p < .001), and led to a higher previous day (prior to assessment) quit rate (p < .03). At the six-month follow-up, the percentage of quitters in the program group was 14.28%, whereas no smokers quit smoking in the control group (p < .04), and Project EX had a significant influence on future smoking expectation (p = .006) and overall level of 30-day smoking. CONCLUSIONS: Results for the Project EX school-based clinic are promising for adolescent smokers in Spain, although difficulties in recruitment and high attrition are of concern. Findings and limitations are discussed and suggestions for future research are suggested. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
