基于 SEM 模型的慢性胃炎患者报告结局量表测评.

Objective To test the reliability and validity of the Chronic Gastritis Patient Reported Outcomes（PROISCD-CG) scale, and to provide the scientific basis for evaluating the reported outcomes of chronic gastritis patients. Methods A questionnaire survey was conducted on 297 patients with chronic gastritis in the gastroenterology department of two tertiary hospitals in Yunnan Province through convenient sampling. Internal consistency test was performed by calculating Cronbach's α coefficient of each dimension of the common module, the common module, the specific module and the total scale. The correlation of item dimensions was analyzed. Confirmatory factor analysis was used to analyze the construct validity, and the convergent validity, combined reliability and discriminant validity of the revised scale were tested. Results The Cronbach's α of the total scale is 0.86, the Cronbach's α of the common module is 0.82, the Cronbach's α of each dimension of the common module is 0.61 to 0.76，and the Cronbach's α of the specific module is 0.82. The correlation of item dimensions is good, and the correlation coefficients of the PHD, MHD, SHD, and SBD dimension scores with the scores of the common module were 0.78，0.79，0.77 and 0.66 （P < 0.05）. Validation factor analysis indicated that some of the entries of the original scale were of poor quality and had poor structural validity. The CMIN/DF of the revised scale is 2.91，the RMSEA value is 0.08, and the GFI，IFI，TLI，and CFI indices have increased to closer to 0.90，and the difference of each entry for the dimension to which it belonged was statistically significant （P < 0.05）. Convergent validity was moderate, composite reliability was moderate, and discriminant validity was moderate. Conclusion The overall reliability of the PROISCD-CG scale is good, and the dimensions of each item are reasonably divided. The structural validity of the original scale is average, but the structural validity of the revised scale has improved. Some items in the PROISCD-CG scale need to be revised and further validated.
