OBJECTIVE: To culturally translate the cardiff acne disability index(CADI) into Korean, and to examine its relationship with clinical acne severity,pathological patterns, and general quality of life(Qo L).METHODS: The CADI was culturally and lin-guistically translated into Korean via translation,back-translation, and face validity test process. Two hundred and fifty-four Korean adolescents were asked to complete the Korean version of the CADI(K-CADI), the Phlegm Pattern, the Cold-Heat Pattern, and the Korean version of the General Health Questionnaires. A clinician estimated acne severity for the adolescents, using the Korean Acne Grading System. Finally, reliability and validity of the K-CADI was examined, and the relationships between acne severity, Phlegm, Cold, and Heat patterns, and Qo L level were examined via pathway ***: The K-CADI had satisfactory internal consistency(α = 0.827). The examination of construct validity indicated that the K-CADI had one factor(explaining 59.6% of the total variance). Pathway analysis showed satisfactory model fit(normal fit index = 0.960 and comparative fit index = 0.983),and acne-related Qo L was determinant to Phlegm,Heat, and Cold patterns(0.13-0.27 of β), and Phlegm and Heat patterns lowered one's Qo L level(0.17-0.34 of β).CONCLUSION: The K-CADI is a valid and reliable instrument. Phlegm and Heat patterns should be managed when treating acne since they have a moderating effect on general Qo L aggravation.
