Background : The Cigarette Dependence Scale (CDS-5) was developed by Etter et al. to measure the degree of a smoker's dependence. This may improve the weakness of the Fagerstrom Test for Nicotine Dependence (FTND). In Korea, there has not been any study to verify the validity of CDS-5. Methods : We administered the FTND and the CDS-5 at one health checkup hospital. Urine cotinine was measured to test its correlation with each test. In addition, the internal consistency of each test was confirmed by Cronbach's alpha coefficient. We analysed the distribution of the items in CDS-5 and conducted factorial analysis of the questionnaire. We also did a stratified analysis according to age groups and smoking amount. Results : Of the 245 subjects, 237 were male and 8 were female. The mean±standard deviation scores for FTND and CDS-5 were 4.2±2.4 and 18.0±3.4, respectively. The internal consistency (Cronbach's alpha) of CDS-5 was 0.720, which was higher than that of FTND (0.633). The correlation with urine cotinine was also higher for CDS-5 (r=0.461) than for FTND (r=0.422). While the Cronbach's alpha of FTND was merely 0.53 in the 50 and older age group, that of CDS-5 was about 0.7, irrespective of age. Conclusions : The internal consistency and correlation with urine cotinine were better for CDS-5 than for FTND. Therefore, there is a greater need to use and to study the CDS-5. (
