Methods The Wisconsin Smoking Withdrawal Scale was translated into Korean and then back-translated into English. The authors reviewed the translation and back-translation and approved the final questionnaire draft. The validity and reliability of the WSWS-K were evaluated based on data collected from 300 participants. Construct validity was evaluated with a confirmatory factor analysis. Criterion-related validity was assessed by examining the relationships between the subscales of the WSWS-K and the matched items of the Korean version of the Minnesota Nicotine Withdrawal Scale (MNWS-K). Results The participants were predominantly male (93.6%) and the mean age was 59.23 ± 15.19 years. The confirmatory factor analysis revealed that fit indices (namely, the goodness-of-fit index, adjusted goodness-of-fit index, comparative fit index, and the normed fit index) exceeded or approached 0.9. Cronbach’s alpha for the entire scale was 0.87. The total score of the WSWS-K had a statistically significant positive correlation with that of the MNWS-K (Pearson’s correlation coefficient, 0.768; p < 0.01). Additionally, we performed linear regression between the WSWS-K and MNWS-K scores after adjusting for age, gender, comorbidity, and smoking history. After this adjustment, the p value of the WSWS- K was < 0.001. Conclusions The WSWS-K had satisfactory validity and reliability. The WSWS- K can be used with acceptable validity and reliability in research and clinical evaluation of Korean smokers.http://www.kjim.org/upload/pdf/kjim-2018-355.pdfsmoking cessationvalidity and reliabilitytranslations
