Abstract

BACKGROUND: The patient-rated wrist evaluation (PRWE) score is one of the most common clinical instruments used as an outcome measurement tool for distal radius fractures and other upper extremity conditions. The purpose of this study was to translate the PRWE into its Persian version and to evaluate its validity and reliability in patients with upper extremity conditions.

METHODS: One hundred and fourthly one adult patients with upper extremity conditions participated in this ethical board approved study from August 2015 to May 2016. After translating the original version of the PRWE into Persian, all patients filled out the PRWE in addition to the VAS (Visual analogue scale) and DASH questionnaires. For evaluating reliability, after three days the researchers called back some of the patients who did not receive treatment or any changes in symptoms and asked them to complete the PRWE retest (104 patients).

RESULTS: Cronbach's alpha was calculated as high as 0.934, implying very reliable internal consistency. After each item deletion, the Cronbach's alpha was still constant (range: 0.926 to 0.936). Intraclass correlation coefficient was 0.952 and this showed excellent test-retest reliability. The correlation coefficient between the PRWE and DASH scores was strong. Multivariable analysis showed an association between the PRWE and years educated.

CONCLUSION: Our study has shown that the Persian version of the PRWE is valid and reliable for patients with upper extremity conditions.
