英文版腕关节功能患者自评量表的汉化及其信度研究

目的 研究中文版腕关节患者自行评估量表(PRWE)在桡骨远端骨折患者功能评定中的重测信度和内部的一致性。方法 运用中文版和英文版的PRWE分别对5l例桡骨远端骨折患者进行量表的重测信度和内在一致性对比观察。用Intra-class Correlation Coefficient(ICC)来表示量表的重测可信度；用Cron-bach Alpha来表示量表的内部一致性。结果 中文版的PRWE信度良好，ICC范围为0．88～0．92；内部一致性也较高，Cronbach Alpha值介于0．87-0．97之间，均大于0．70。结论 中文版PRWE具有良好的重测信度和内部一致性．可以作为桡骨远端骨折华人患者的主观功能评定量表。

The chinese version of the patient rated wrist evaluation (PRWE): cross-culture adaptation and reliability test

Objective To evaluate the test-retest reliability and internal consistency of a Chinese version ofthe PRWE in a group of patients with distal radius fracture and to compare it with the original PRWE. MethodsThe original PRWE was translated into Chinese. Test-retest reliability was obtained by repeating the PRWE to thesame subjects in one week interval and presented by intra-class correlation coefficient (ICC), internal consistencywas measured by Cronbachs coefficient alpha. Results The Chinese PRWE has good test-retest reliability and in-ternal consistency which are equivalent to the results from the English PRWE. The ICC for the Chinese PRWE rangedfrom 0. 88 to 0. 92. and Cronbach Alpha for the Chinese PRWE ranged from 0. 87 to 0. 97. Conclusion The Chi-nese version of PRWE is equivalent to the original PRWE with acceptable level of reliability and internal consistency.It is a good functional assessment tool for patients with distal radius fractures.
