title: Standardization Study of the Korean Version of the Stages of Change Readiness and Treatment Eagerness Scale for Smoking Cessation (K-SOCRATES-S) and Its Predictive Validity.
abstract: OBJECTIVE
  The purpose of the study was to develop the Korean version of the Stage of Change Readiness and Treatment Eagerness Scale for Smoking Cessation (K-SOCRATES-S) based on the Korean version of the Stages of Readiness for Change and Eagerness for Treatment scale (K-SOCRATES). This paper also demonstrates its reliability and validity among patients with nicotine dependence in South Korea.
  
  
  METHODS
  At seven healthcare promotion centers in Gyeonggi-do, 333 male smokers aged 20 to 70 who visited smoking cessation clinic were recruited for this study and the K-SOCRATES-S was administered. After three months, the number of respondents who successfully stopped smoking was assessed by testing their urine cotinine level. Subsequently, exploratory factor analysis was performed to verify the reliability and validity of the K-SOCRATES-S. Also, a logistic regression analysis was performed to examine the variables that can predict the successful cessation of smoking on subscales of the K-SOCRATES-S.
  
  
  RESULTS
  Exploratory factor analysis of the K-SOCRATES-S showed that the scale consisted of three factors: Taking Steps, Recognition, and Ambivalence. The scales measuring Taking Steps and Recognition in this scale had a significantly positive correlation with the scores observed on Kim's smoking cessation motivation scale. The scales measuring Taking Steps and Recognition had a significantly negative correlation with Ambivalence. Overall, the results indicate that the K-SOCRATES-K scale showed high validity.
  
  
  CONCLUSIONS
  The K-SOCRATES-S developed in the present study is highly reliable and valid for predicting a patient's likelihood of success in quitting smoking among patients who want to cease smoking.
