Effectiveness of smoking cessation program for male adolescents in South Korea

The objective of this study was to implement and verify the effectiveness of a smoking cessation program based on a cognitive behavioral model, composed of six sessions. Participants included 80 male middle school students who smoked. They were divided into experimental (n = 35 students) and comparison (n = 45 students) groups, and the smoking cessation program was conducted in the experimental group. Results of self-report scales for smoking behaviors and urinary cotinine and CO levels before and after the program were statistically analyzed with mixed regression including factors for group, time, and a group-by-time interaction. The results indicated that the group effect, time effect, and group-by-time interaction effect were significant for the nicotine dependency. The variation patterns in the two groups became significantly different over time as nicotine dependency drastically decreased in the experimental group, whereas those in the comparison group showed little change from pre-program examination to post-program examination. Significant time effects were observed for smoking cessation efficacy and urinary cotinine levels, reflecting increased smoking cessation efficacy and decreased cotinine levels in both groups across time. The results suggest that this six-week smoking cessation program in male adolescents in South Korea was valid to implement.
