Cross-cultural adaptation and psychometric testing of the Arabic version of the Patient-Rated Wrist Hand Evaluation (PRWHE-A) in Saudi Arabia

Abstract

Purposes: The purposes of this study was to 1) perform a cross-cultural Arabic translation for the Patient-Rated Wrist and Hand Evaluation (PRWHE-A) using standardized guidelines and, 2) to test the psychometrics properties of the translated measure.

Methods: A total of 48 patients with variety of hand disabilities, a mean age of 47 ± 16 years were recruited and assessed two times. The intraclass correlation coefficient (ICC) was used for assessing test-retest reliability of the PRWHE-A and its subscales while Cronbach's alpha (CA) was used for assessing the internal consistency. Construct validity was assessed by examining the strength of the correlation between the PRWHE-A and the Arabic version of the Disability of the Arm, Shoulder and Hand (DASH-A).

Results: The PRWHE-A demonstrated excellent test-retest reliability (ICC= 0.97) and internal consistency (CA= 0.96). The DASH-A demonstrated moderately to low correlation (r= 0.64) with the PRWHE-A.

Conclusions: The results of this study indicated that PRWHE-A is a reliable and valid assessment tool and can be used in patients with different wrist/hand disabilities whose primary language is Arabic.
