Abstract

BackgroundThere is a need for outcome measurement instruments for evaluation of disability after trauma. The Patient-Rated Wrist Evaluation (PRWE) is a self-administered region-specific outcome measuring instrument developed for use in evaluating disability and pain of the wrist. The aim of this study is to translate and to cross-culturally adapt the PRWE for use in a Swedish patient population. Moreover, we aim at investigating the PRWE in terms of validity, reliability and responsiveness.MethodsWe performed a translation and cross-cultural adaptation of the PRWE to Swedish (PRWE-Swe), utilising the process recommended by the American Association of Orthopedic Surgeons. A total of 124 patients with an injury to the wrist were included in the study. They filled in the PRWE and the DASH questionnaires at two separate occasions.ResultsReliability of the PRWE in terms of internal consistency (Cronbach's alpha 0.97) and test-retest stability (intraclass correlation coefficient 0.93) were excellent. Face validity and content validity were judged as good. Criterion validity assessed as the correlation between the PRWE and the DASH was also good (Spearman's rho = 0.9). Responsiveness measured by the standardized response mean (SRM) was good with an SRMPRWE of 1.29.ConclusionThis Swedish version of the PRWE is a short and easily understood self-administered questionnaire with good validity, reliability, and responsiveness. Our results confirm that the PRWE is a valuable tool in evaluating the results after treatment of a wrist injury.

Highlights

There is a need for outcome measurement instruments for evaluation of disability after trauma
On analyzing all the complete DASH questionnaires in the chronic group, we found an intraclass coefficient of 0.93, which confirms that the Patient-Rated Wrist Evaluation (PRWE) is as reliable a tool for wrist evaluation as the DASH
Analysis of missing values A total of 248 PRWE and 248 DASH questionnaires from 124 patients were returned; 121 patients filled out Discussion Our results showed that the PRWE is a self-administered questionnaire with good validity, reliability, as well as responsiveness and is helpful in evaluating the results after treatment of a wrist injury or disease of the wrist

Summary

Introduction

There is a need for outcome measurement instruments for evaluation of disability after trauma. The outcome after treatment of musculo-skeletal injuries and diseases has traditionally been measured by the range of motion, muscle strength, radiographic appearance, as well as the subjective judgement of the examiner. In the field of upper limb injuries and diseases, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire has evolved as one of the most important self-reported instruments [2,3,4,5]. It has been adapted and validated for use in Swedish language [5]. One study claims that the PRWE should be preferred over the DASH when assessing wrist function, since it contains fewer items than the DASH and is quicker and easier for the patient to fill out [9]
