Abstract
Background
We developed a simplified Chinese version of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire (shorthand for DASH-CHNPLAGH) by conducting cross-cultural adaptation and evaluating its reliability and validity.
Methods
Both the forward and back translations were performed by language officers and medical professionals from different fields to translate the original DASH version into the DASH-CHNPLAGH version with minimized culture discrepancies. A total of 300 patients with upper extremity disorders were recruited to complete two DASH-CHNPLAGH questionnaires with 3-week test interval time.
Results
The intraclass coefficient (ICC) and Cronbach’s alpha for the 30-item disability/symptom of the DASH-CHNPLAGH was 0.94 and 0.96, respectively, which were relatively high among that reported in previous literatures. DASH-CHNPLAGH showed a positive correlation with a visual analogue scale (VAS) and a negative correlation with SF-36 items.
Conclusion
The simple Chinese version of DASH is a reliable and valid measurement for patients with upper extremity problems.
