Validation Study of Kim's Smoking Cessation Motivation Scale and Its Predictive Implications for Smoking Cessation.
OBJECTIVE
The purpose of this study was to develop a scale to measure motivation for smoking cessation. Motivation is known to be important for success of smoking cessation. The reliability of the scale was assessed and its predictive validity for smoking cessation was evaluated.


METHODS
We recruited 333 men aged 20 to 70 that visited smoking cessation clinics at seven public health centers. The demographic characteristics were recorded and the Korean version of Stages of Readiness for Change and Eagerness for Treatment Scale for Smoking (K-SO-CRATES-S) performed. A smoking cessation motivation scale was developed with 10 questions based on the theory of motivation enhancement therapy.


RESULTS
The motivation scale was composed of four subscales based on the factor analysis; each subscale had an adequate degree of internal consistency. In addition, the newly developed scale had a high degree of validity based on its significant correlation with the smoking version of SOCRATES. Moreover, the precontemplation level of motivation was found to significantly predict the success of smoking cessation. And one of the subscales of the Korean Nicotine Dependence Syndrome Scale (K-NDSS), stereotypy which also significantly predicted the success of smoking cessation, significantly correlated with the preparation 1 and 2 level of motivation.


CONCLUSIONS
The smoking cessation motivation scale with 10 questions that was developed in this study was a highly reliable and valid scale for the prediction of success for smoking cessation for those who wanted to stop smoking.
