We developed a Korean version of the disabilities of arm, shoulder, and hand outcome questionnaire (K-DASH) by performing cross-cultural adaptation and evaluated the reliability and validity of the K-DASH. The K-DASH, SF-36, and Visual Analog Scale (VAS) for pain were administered to 161 patients with arm, shoulder, and hand problems. The internal consistency of the disability/symptom scores of the K-DASH was high (Cronbach's alpha 0.94). The retest assessed 131 of the 161 patients. The intraclass correlation coefficient was 0.91. The construct validity was evaluated using the correlations between the K-DASH and the SF-36 and VAS. The physical and mental component summary scales of the SF-36 and the VAS at rest and during activity were significantly correlated with the DASH disability/symptom scores. Despite the linguistic and cultural differences, the reliability and validity of the K-DASH were just as excellent as those of the original DASH.
