Translation and Validation of the Finnish Version of the Patient-Rated Wrist Evaluation Questionnaire (PRWE) in Patients with Acute Distal Radius Fracture.
OBJECTIVE
Patient-rated outcome measures have become increasingly important in clinical research. They provide research and clinical tools which can be utilized in the assessment of patient recovery and treatment efficacy. The purpose of our study was to translate and validate the original version of the PRWE form into Finnish.


METHODS
We conducted the translation of the PRWE questionnaire according to standardized guidelines. Patients (N = 119) with an acute distal radius fracture were recruited, and they completed the PRWE and QuickDASH questionnaires at 2 months and 4 months after the wrist injury.


RESULTS
The mean answering times were 52 days (standard deviation [SD] 9.8 days) and 116 days (standard deviation [SD] 14.8 days), respectively. Both the internal consistency (Cronbach's alpha) of 0.976 and the intraclass correlation coefficient (ICC) of 0.992 (95% CI 0.966-0.998) showed excellent reliability for the total PRWE score. The correlation coefficients between the total score, the subscales, and for improvement over time for PRWE and QuickDASH were excellent. The responsiveness was good with an effect size of 0.83 and a standard response mean of 1.22.


CONCLUSIONS
Our study shows that the Finnish version of the PRWE is reliable, valid, and responsive for the evaluation of pain and disability after distal radius fracture.
