Résumé
OBJECTIVES: The Nicotine Dependence Syndrome Scale has been reported as valid and useful measure for assessment of the level and the pattern of nicotine dependence. The aim of this study is to prove the validity and reliability of the Korean version of Nicotine Dependence Syndrome Scale and find out its predictive effect on smoking cessation. METHODS: 274 smokers who visited the public health center smoking cessation clinic were enrolled in this study. Fagerstrom test and K-NDSS were administered and the subjects started smoking cessation after basic assessment was done with the aid of bupropion and nicotine patch. Six month later smoking cessation success or failure was assessed through self report. RESULTS: K-NDSS factor structure was very similar to the original version of NDSS and has proved to be valid and reliable. Cronbach's alpha for K-NDSS-Total was .90, and Cronbach's alpha for each sub-factors are ranged from .66 to .85. Sub-factor, continuity and stereotypy can predict the possibility of smoking cessation success or failure. CONCLUSION: K-NDSS was proved to be a valid and a reliable measure of nicotine dependence, and its sub-factor continuity and stereotypy has predictive characteristic on smoking cessation.
