Scientific/Clinical ArticleEvaluation of the Chinese version of the Disability of the Arm, Shoulder and Hand (DASH-HKPWH): Cross-cultural adaptation process, internal consistency and reliability study
Section snippets
New calculation for the DASH score
The main section of the DASH includes a 30-item scale according to the degree of difficulty and severity of pain in performing various activities during the week before completing the questionnaire. Items 1–21 and 29 relate to the level of difficulty in performing various physical activities. The severity of symptoms, including pain, tingling, weakness, and stiffness, are included in items 24–28. Items 22 and 23 relate to social activities, and item 30 asks about an individual's psychological
Cross-cultural adaptation
The synthesis of the forward translation of the questionnaire was produced with little difficulty, except when there were several items that required a longer discussion before achieving a consensus, such as item 20 (managing transportation needs) and the first item (using usual techniques) in both the DASH-W and DASH-SP modules. There were some discrepancies between the two back-translations because the two translators had different opinions regarding more colloquial language. For example, in
Discussion
The aim of the present study was to demonstrate the cross-cultural adaptation process and evaluate the face validity, internal consistency, and reliability of the DASH-HKPWH. Our study showed that this new questionnaire maintains the linguistic and cultural elements, as well as the internal consistency and reliability, of the original version.
When developing a scale, it is important to eliminate items that are repetitive or irrelevant to the body part being investigated or studied. Careful
Conclusion
The DASH-HKPWH is a self-administered questionnaire that can be used in clinical settings to subjectively identify any changes in symptoms by patients before commencing treatment. The application of the DASH and other relevant upper-extremity measuring instruments allows clinicians to understand their patients' conditions more clearly. The results suggest that the DASH-HKPWH is a reliable outcome measure for assessing patients with upper extremity disorders. To the best of our knowledge, this
