Résumé : | Background The Shoulder Pain and Disability Index (SPADI) is a widely used patient-reported outcome questionnaire in patients with shoulder diseases; however, the structural validity and the internal consistency of the Turkish SPADI is unclear in rotator cuff disease. Objective To assess the internal structure of the Turkish SPADI in patients with rotator cuff disease. Methods A total of 109 patients with unilateral rotator cuff disease were assessed. The COnsensus-based Standards for the selection of health Measurement INstruments checklist was used for the methodological design of the study. A confirmatory factor analysis was performed, and the model fit was assessed by using the comparative fit index (CFI), the Tucker-Lewis index (TLI), the root mean square error of approximation (RMSEA), and the standardized root mean square residual (SRMR). The factor structure was examined with a principal component analysis. The internal consistency was assessed using Cronbach's alpha. Results The validity of the two subscales was not confirmed. The principal component analysis showed the Turkish SPADI consisted of one factor, and the one-factor model of the Turkish SPADI also was not confirmed. When two items were deleted, the one-factor model of the new version of the Turkish SPADI had a better fit (CFI = 0.978, TLI = 0.971, RMSEA = 0.058, SRMR = 0.043). The internal consistency of the new version of the Turkish SPADI was high (Cronbach's alpha = 0.92, 95% CI = 0.90?0.94). Conclusions We suggest that the modified version of the Turkish SPADI should be used for patients with rotator cuff disease. The total score of the modified version should be considered. |
