한국어판 Cigarette Dependence Scale-12(CDS-12)의 신뢰도와 타당도 연구

The Reliability and Validity of the Korean Version of the Cigarette Dependence Scale-12(CDS-12)

Objectives：This study aimed to assess the reliability and val-idity of the Korean version of the Cigarette Dependence Scale-12 (CDS-12). Methods：Participants were 189 male and 8 female smokers from a public health center. We administered the Korean Version of the Fagerström Test for Nicotine Dependence (FTND), the CDS-12, and two shorter versions of the same measures [the CDS-5 and the Heavy Smoking Index (HIS)] to the participants, who started smoking cessation attempts after this initial assessment. At their first visit, we measured the participants’ carbon monoxide (CO), and participants revealed their cessation state through self-report at four weeks, six weeks, and six months. Results：Cronbach’s alpha, which indicates internal reliability, was 0.889 for the CDS-12 and 0.741 for the CDS-5. Split-half reliability was 0.882 for the CDS-12 and 0.650 for the CDS-5. The Pearson correlation coefficients, indicating the relationships between the FTND and either the CDS-12 or the CDS-5, were 0.675 and 0.746, respectively. The Pearson correlation coefficients between the HSI and the CDS-12 or the CDS-5 were 0.662 and 0.756, respectively. The CDS-12 score at baseline predicted smoking cessation after 4 weeks. Conclusion：The CDS-12 is a valid and reliable measure of nicotine dependence.
