Reliability and validity of the German version of "the Patient-rated Wrist Evaluation (PRWE)" as an outcome measure of wrist pain and disability in patients with acute distal radius fractures.

The aim was to test the reliability and validity of the German version of the Patient-rated Wrist Evaluation (PRWE) for patients with acute distal radius fractures. To estimate the reliability and construct validity, 44 patients completed a questionnaire booklet containing the German PRWE, the Short Form-36 (SF-36), and the Disability of the Arm, Shoulder, and Hand (DASH) four to six weeks after the fracture, and the PRWE again seven days later. For reliability, the intraclass correlation coefficient (ICC) was 0.94 for the PRWE total score. ⋯ The PRWE total score showed a moderate correlation with the DASH (0.62) and the SF-36 subscale bodily pain (0.58). Low correlations were found with other scales of the SF-36. Based on our results the German PRWE is a practical, reliable, and valid instrument and can be recommended to measure patient-rated pain and disability in German-speaking patients with acute distal radius fracture.

AbstractThe aim was to test the reliability and validity of the German version of the Patient-rated Wrist Evaluation (PRWE) for patients with acute distal radius fractures. To estimate the reliability and construct validity, 44 patients completed a questionnaire booklet containing the German PRWE, the Short Form-36 (SF-36), and the Disability of the Arm, Shoulder, and Hand (DASH) four to six weeks after the fracture, and the PRWE again seven days later. For reliability, the intraclass correlation coefficient (ICC) was 0.94 for the PRWE total score. Its internal consistency was 0.89 (Cronbach's alpha). The PRWE total score showed a moderate correlation with the DASH (0.62) and the SF-36 subscale bodily pain (0.58). Low correlations were found with other scales of the SF-36. Based on our results the German PRWE is a practical, reliable, and valid instrument and can be recommended to measure patient-rated pain and disability in German-speaking patients with acute distal radius fracture.
