CHOOS-PS demonstrated excellent test-retest reliability (ICC = 0.848–0.919) and strong internal consistency (Cronbach's alpha = 0.892).
Correlation analysis reveals CHOOS-PS has strong relationships with OHS (rs = 0.874) and moderate correlations with WOMAC and SF-36.
Using confirmatory factor analysis, CHOOS-PS shows a good fit (RMSEA = 0.050, CFI = 0.995), supporting its construct validity.
The CHOOS-PS scale exhibits good responsiveness in assessing functional outcomes in chronic hip joint disease patients post-THA.
