Boonard M Objective: To assess the reliability and validity of the Thai version of the Disability of the Arm, Shoulder, and Hand (KKUDASH)questionnaire in patients with brachial plexus injuries.
Material and Method: The Thai KKU-DASH version was performed based on translation/back translation methodology.Thirty-four Thai-speaking patients with brachial plexus injuries completed the KKU-DASH and the 36-item short-form healthsurvey (SF-36) questionnaires preoperatively and then were reassessed for test-retest reliability two months later. Reliabilitywas investigated for reproducibility and internal consistency. The validity was evaluated by using component analysis and thecorrelations coefficients between the KKU-DASH and the SF-36.
Results: The internal consistency of the degree of difficulty, severity of pain, and social activity domains of the KKU-DASHwas good to excellent (Cronbach’s alpha 1.00, 0.75, and 1.00). The intraclass correlation coefficient (ICCs) for the test-retestreliability was 0.52. For the degree of difficulty, severity of pain, social activity, and psychological effect on self-image, the ICCwere 0.5, 0.45, 0.57, and 0.53 respectively. The convergent validity between the KKU-DASH and SF-36 was -0.76. Theconvergent validity of each domain between both instruments ranged from 0.46 to 0.69 and the strongest correlation wasobserved in the social activity domain.
Conclusion: According to the reliability and validity testing, the KKU-DASH questionnaire is suitable for Thai-speakingpatients with brachial plexus injuries.
