Abstract:
Objective:To test the reliability and validity of the Chinese version of the Demoralization Scale-Ⅱ (DS-Ⅱ) in maintenance hemodialysis (MHD) patients.Methods:This was a cross-sectional study. From October 2021 to February 2022, 989 patients who received MHD in 16 hospitals in Xiangyang City, Hubei Province, were selected by convenience sampling as the study subject. The patients were investigated with the General Information Questionnaire, DS-Ⅱ, Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) . The correlation coefficient and critical ratio were used for project analysis. The reliability of the total scale and sub-scale were tested by Cronbach 's α coefficient, split half reliability coefficient, retest reliability coefficient. The exploratory factor analysis was used to determine item pool dimension and scale structure, and the confirmatory factor analysis was used to test the structural validity of the scale. We tested the correlation among the scores of SAS, SDS and Chinese version of DS-Ⅱ. A total of 989 questionnaires were distributed, and 920 valid questionnaires were recovered, with a valid recovery rate of 93.02% (920/989) . Results:The correlation coefficient among each item score and the total score of the scale was 0.679 to 0.777 ( P<0.05) . The critical ratio of each item in high score group and low score group was 21.637 to 30.719 ( P<0.05) . The total content validity coefficient of the scale was 0.984, and the content validity coefficient of each item was 0.875 to 1.000. Two common factors were extracted after exploratory factor analysis, and the cumulative variance contribution rate was 59.844%. The confirmatory factor analysis showed that the model fitted well, and the correlation coefficients among items and dimensions were 0.687 to 0.803. The total score of DS-Ⅱ and each factor score were positively correlated with scores of SAS and SDS ( P<0.05) . Cronbach 's α coefficient of the total scale was 0.944, and the split half reliability Guttman 's coefficient was 0.884, and the retest reliability coefficient was 0.909. Conclusions:The Chinese version of DS-Ⅱ has good reliability and validity in MHD patients.
