[Meta-analysis of effects on adolescent smoking cessation programs in Korea].

Purpose: Meta-analysis of this study was to analyze the character of adolescent smoking cessation programs, to calculate the effect size according to variables and to compare the weighted mean effect sizes on adolescent smoking cessation programs in Korea.

Methods: Twenty two studies for meta-analysis were selected from dissertations, theses, articles and research papers that had been published from 1995 to 2003. The selected studies had a randomized or nonequivalent control group in a pretest-post test design and had reported statistical value to calculate the effect size.

Results: The mean number of sessions was 6.5. The education time per each session varied from 40 to 150 min and the most applied theories were Bandura's social-cognitive theory and the cognitive-behavioral theory. Smoking-knowledge, smoking-attitudes and smoking-amount showed high effects on the first post test after mediating adolescent smoking cessation programs according to the criteria of Cohen. The effect size of urine-cotinine found no homogeneity on the first post test, but it was significantly effective on the second post test.

Conclusion: Adolescent smoking cessation programs analyzed in this study were relatively effective in smoking abstinence.
