Abstract

Background

Although the Oxford Hip Score has been translated and validated in several languages, there is currently no Chinese version of the outcomes measurement. Our study aims to crossculturally adapt and validate the Oxford Hip Score into a simplified Chinese version.

Questions/purposes

We tested the (1) reliability; (2) validity; and (3) responsiveness of the Chinese version of the Oxford Hip Score.

Methods

First we translated the Oxford Hip Score into simplified Chinese, then back into English, then held a consensus meeting to achieve the final simplified Chinese version. Then we evaluated the psychometric properties of Chinese version of the Oxford Hip Score in patients undergoing total hip arthroplasty (THA). All patients undergoing THA between July and December 2012 were invited to participate in this study; a total of 108 (79% of 136 invited) did so. To assess the test-retest validity, all participants completed the Chinese version of the Oxford Hip Score again with a 2-week interval. Pearson correlation coefficient was used to evaluate the construct validity between the Chinese version of the Oxford Hip Score and visual analog scale (VAS), Harris hip score, and eight individual domains of the SF-36. Responsiveness was demonstrated by comparing the pre- and postoperative scores of the Chinese version of the Oxford Hip Score.

Results

The test-retest reliability with intraclass correlation coefficient (0.937) and internal consistency with Cronbach’s alpha (0.91) were excellent. The Chinese version of the Oxford Hip Score correlated with the Harris hip score (0.89, p < 0.01), VAS (−0.79, p < 0.01), and Physical Functioning (0.79, p < 0.01) and Bodily Pain (0.70, p < 0.01) domains of SF-36, which suggested construct validity. No floor or ceiling effects were found. The effect size and standardized response mean values were 3.52 and 3.31, respectively, indicating good responsiveness.

Conclusions

The Chinese version of the Oxford Hip Score showed good reliability, validity, and responsiveness in evaluating standard Chinese-speaking patients with hip osteoarthritis undergoing THA. It can be used by clinical surgeons as a complement to the traditional outcome measures.
