Reliability and Validity of the Korean Version of the Dimensions of Tobacco Dependence Scale for Adolescents.

This study assessed the reliability and validity of the Korean version of the Dimensions of Tobacco Dependence Scale (DTDS) for adolescents in Korea. The DTDS, Modified Fagerström Tolerance Questionnaire (M-FTQ), and urine nicotine test were administered to 360 Korean adolescents. The collected data were analyzed using SPSS 21.0 and AMOS 21.0. The construct validity, criterion validity, test-retest reliability, internal consistency reliability, and the area under the curve (AUC) of the Korean version of the DTDS were evaluated. The 4-subscale model of the DTDS (with social, emotional, physical, and sensory subscales) was validated using confirmatory factor analysis, and criterion validity was demonstrated with the M-FTQ. Furthermore, the AUC of the DTDS was 83.1. The Cronbach's α coefficient for internal consistency was .96, demonstrating sufficient test-retest reliability. The Korean version of the DTDS is a reliable and valid measure of tobacco dependence among Korean adolescents.
