简短炎症性肠病生活质量问卷的信效度评价

背景简短炎症性肠病问卷(the short inflammatory bowel disease questionnaire,SIBDQ)广泛用于评估炎症性肠病(inflammatory bowel disease,IBD)患者的健康相关生活质量.目的引进SIBDQ量表并评估其信效度.方法根据Brislin模型的翻译-回译流程得到中文版SIBDQ(SIBDQ-C).对2020-06/2021-06就诊于广州中医药大学第一附属医院、中山大学第一附属医院IBD患者进行测评;使用克朗巴赫系数、分半信度和重测信度检验量表的信度,使用验证性因子分析评价其结构效度.结果共发放问卷113份,最终回收112份.SIBDQ-C的Cronbach’sα为0.90,折半系数为0.86;量表四个维度间的Spearman相关系数在0.61到0.77之间;验证性因子分析的近似误差方根、非范拟合指数、比较拟合指数、拟合优度指数分别为0.08、0.93、0.97、0.92;不同粪便形态患者的SIBDQ-C总分及各维度得分均有统计学差异(P<0.05).结论SIBDQ-C具有良好的信度及效度,可以用于临床测量我国IBD患者的生活质量.

Reliability and validity of the Chinese version of the short inflammatory bowel disease questionnaire

BACKGROUND The short inflammatory bowel disease questionnaire(SIBDQ)is a widely used assessment tool to measure the health-related quality of life of patients with inflammatory bowel disease(IBD).AIM To translate and validate the SIBDQ in Chinese IBD patients.METHODS A simplified Chinese version of SIBDQ(SIBDQ-C)was obtained according to Brislin’s translation and back-translation procedure.The patients with IBD were measured in the First Affiliated Hospital of Guangzhou University of Chinese Medicine and the First Affiliated Hospital of Sun Yat-Sen University between June 2020 and June 2021.Cronbach’sα,split-half reliability,and intraclass correlation coefficient(ICC)were used to test the reliability of the SIBDQ-C.Confirmatory factor analysis was used to evaluate its structural validity.RESULTS A total of 113 patients with IBD were enrolled,and 112 were eventually included for analysis.Cronbach’sαof the SIBDQ-C was 0.90,and split-half coefficient was 0.86.ICCs of the four dimensions ranged from 0.61 to 0.77.Confirmatory factor analysis showed that root mean square error of approximation,non-normed fit index,comparative fit index,and goodness-of-fit index were 0.08,0.93,0.97,and 0.92,respectively.There were significant differences in the SIBDQ-C score and the scores of four dimensions in patients with different fecal characters(P<0.05).CONCLUSION The SIBDQ-C has good reliability and validity,which can be used to measure the quality of life of patients with IBD in mainland China.
