Abstract

Background : The Patient Rated Wrist/Hand Evaluation (PRW/HE) is a specific questionnaire designed to measure wrist/hand pain and disabilities. The questionnaire was validated to provide various scales by asking questions regarding wrist-hand injury of a patient. It has also been translated into several languages. Therefore, we translated and adapted the questionnaire into Thai version for hand therapy clinic.Objectives : To translate and to cross-culturally adapt the PRW/HE into Thai (PRW/HEThai) and to evaluate it’s the reliability and validity.Methods : The original version PRW/HE was translated with cross cultural adaptation into Thai (PRW/HE-Thai). A total of 148 outpatients from Occupational therapy (OT) hand therapy clinic were included in the study. They completed questionnaire, PRW/HE-Thai, The Disabilities of the Arm, Shoulder and Hand (DASH-Thai) at first visit and the PRW/HE-Thai again 14 days later. Reliability was measured by determining test - retest reliability (intraclasscorrelation coefficient) and internal consistency (Cronbach’s alpha coefficient). Validity was performed using Pearson’s correlation test.Result : Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) for the test-retest reliability of PRW/HE-Thai were 0.94 and 0.89, respectively. The correlation coefficient between PRW/HE- Thai and DASH-Thai scores was 0.76.Conclusion : Thai-version of the PRW/HE is a short and easily understood selfadministered questionnaire. Our results show that PRW/HE-Thai is a practical, reliable and valid instrument and can be recommended to measure patient-rated pain and disability in Thai patients. In the future, the questionnaire should also be compared to objective measurement.
