An exploratory and confirmatory analysis of the oxford hip score: generation of subscales assessing self-reported function and pain

چکیده
Results The proposed number of factors to extract depended on the method employed. Velicer’s Minimum Average Partial test suggested one factor, the Cattell’s scree test and parallel analysis suggested two factors, and the second eigenvalue of 1.04 also suggested two factors. Exploratory factor analysis demonstrated that the 2-factor OHS had most of the items saliently loading either of the two factors. These factors were named ‘Pain’ and ‘Function’ and their respective subscales were created. Cronbach’s alpha was 0.90 for the 12-item summary scale, 0.85 for the 6-item ‘Function’ subscale, and 0.82 for the 6-item ‘Pain’ subscale. Confirmatory factor analysis demonstrated that the 2 factor model of the OHS had somewhat better fit. However, none of the one factor or two factor models was rejected.
