| Background Perceived discrimination has been identified as a main risk factor for depression in maintenance hemodialysis patients. Chronic Illness Rejection and Discrimination Scale （CIRDS） is a measure for assessing perceived discrimination in individuals with chronic disease. However， the Chinese version of CIRDS for maintenance hemodialysis patients has not yet been established.Objective To translate CIRDS into Chinese version and evaluate its reliability and validity in maintenance hemodialysis patients， so as to provide an effective tool for assessing the perceived discrimination among maintenance hemodialysis patients.Methods The Brislin's model for translation， back-translation， cross-cultural adaptation and pre-experimentation was utilized to develop a Chinese version of CIRDS. A coherent of 250 maintenance hemodialysis patients attending Taihe Hospital Affiliated to Hubei Medical College， from July to October 2023 were selected as the research subjects. The formal scale was refined by employing item analysis， exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated using content validity and construct validity. The reliability of the scale was evaluated using Cronbach's α coefficient， test-retest reliability and split-half reliability.Results The Chinese version of CIRDS consisted of 11 items， including 2 factors （perceived discrimination and perceived rejection）. The scale-level content validity index （S-CVI） value was 0.898 and the item-level content validity index （I-CVI） values ranged from 0.875 to 1.000. Two common factors were extracted by exploratory factor analysis and explained 65.41% of the total variance. Confirmatory factor analysis also indicated that the model provided a good fit for the data. The Cronbach's α coefficient of the scale was 0.910， with Cronbach's α coefficients of 0.835 and 0.912 for the perceived discrimination and perceived rejection， respectively. The split-half reliability of the scale was 0.803， and the test-retest reliability was 0.920.Conclusion The Chinese version of CIRDS has excellent reliability and validity， which can be used to evaluate the perceived discrimination in maintenance hemodialysis patients. |
