Use of the transtheoretical model to predict stages of smoking cessation in Korean adolescents.
BACKGROUND
Smoking is popular among Korean male high school adolescents, with the prevalence of 20.7% differing markedly with the type of school, being 16.3% and 27.6% in academic and vocational technical high schools, respectively. The purpose of this study was to identify significant variables that predict stages of smoking cessation among Korean high school students using the transtheoretical model (TTM), in order to provide an empirical basis for developing smoking cessation programs.


METHODS
Cross-sectional data were collected in April and May 2004 from 300 male students at 3 vocational technical high schools in Korean metropolitan areas. The survey variables comprised decisional balance, self-efficacy, stages and processes of change, nicotine dependence, and use of smoking cessation aids.


RESULTS
Current and former smokers comprised 26.3% and 22.7% of the cohort, respectively, of which 71.4% had experienced smoking cessation at least once and 55.1% utilized smoking cessation aids to help stop smoking. Nicotine-free tobacco and nicotine gum were the most common smoking cessation aids. Decisional balance, use of behavioral processes, and higher self-efficacy were significant in explaining stages of smoking cessation after controlling for nicotine dependence.


CONCLUSIONS
The study results suggest that smoking cessation programs developed based on the TTM may help adolescents to progress through stages, with it being important to include information regarding the use of smoking cessation aids.
