The Australian/Canadian Osteoarthritis Hand Index (AUSCAN) is a patient self-reported 15-item questionnaire measuring the severity of hand osteoarthritis symptoms in the respect of pain, stiffness, and function. In this study, we developed a Korean version of the AUSCAN Index (K-AUSCAN) and confirmed its reliability, validity, and responsiveness. The AUSCAN Index was translated into Korean by 3 translators and translated back into English by 3 different translators. In a group of 53 patients with clinical hand osteoarthritis (mean age 58.3 ± 7.6 years), validity was evaluated against other outcome measures, including the Functional Index for Hand Osteoarthritis (FIHOA) and Multidimensional Health Assessment Questionnaire (MDHAQ). Test-retest reliability was assessed at a 2-weeks interval in 51 patients. Internal consistency of K-AUSCAN was evaluated by Cronbach's ±. Responsiveness was measured by standardized response mean (SRM). The test-retest reliability of K-AUSCAN yielded intraclass correlation coefficient of 0.46 for pain, 0.58 for stiffness, and 0.67 for function. The internal consistency of K-AUSCAN was satisfactory with Cronbach's ± of 0.89 for pain and 0.93 for function. The K-AUSCAN index showed good correlation with other measures (r2 was 0.67 for K-AUSCAN pain and MDHAQ pain; r2 was 0.72 for K-AUSCAN function and FIHOA). The pain and function of K-AUSCAN correlated substantially with each other and moderately with stiffness subscale. The average SRM for K-AUSCAN pain, stiffness, and function was -0.92, -0.48, and -0.84, respectively. The Korean version of the AUSCAN Index is a valid, reliable, and responsive tool for the assessment of hand osteoarthritis symptoms.
