摘要：

目的编制科学、规范的炎症性肠病患者症状群评估量表,并进行信效度检验。方法以症状经历模型为指导,通过文献回顾、德尔菲专家函询形成量表初稿;对条目进行描述性定义后进行小样本预调查,根据患者反馈完善量表。便利选取2019年6月—9月在江苏省4所三级甲等综合医院消化科门诊就诊或住院的150例炎症性肠病患者进行问卷调查。运用SPSS 20.0对数据进行项目分析,测定量表的信效度。结果最终形成的炎症性肠病患者症状群评估量表包括18个条目,量表的内容效度指数为0.850,各条目的内容效度指数为0.941~1.000。探索性因子分析提取出5个公因子,累计方差贡献率为77.390%。各因子与总量表间呈正相关,相关系数为0.580~0.857,总量表与炎症性肠病生活质量问卷的相关系数为0.925。总量表的Cronbach’s α系数为0.900,重测信度为0.856。结论炎症性肠病患者症状群评估量表具有良好的信效度,可引导医护人员精准、针对性地评估患者,为患者制订个性化的症状管理措施提供依据。

Abstract:

Objective We developed a scientific and standardized symptom clusters assessment scale for patients with inflammatory bowel disease and performed a reliability and validity test. Methods Guided by the Symptoms Experience Model,our research group developed the first draft of the scale through literature review and Delphi expert consultation. After descriptive defining of the items,we conducted pilot experiment with a small sample size and refined the scale based on patient feedback. 150 patients with inflammatory bowel disease admitted to the Department of Gastroenterology in 4 tertiary hospitals in Jiangsu Province from June to September 2019 were conveniently selected and investigated. The data was analyzed by SPSS 20.0 to determine the reliability and validity of the scale. Results The final Symptom Cluster Scale for Inflammatory Bowel Disease consisted of 18 items. The content validity index of the scale was 0.850,and the content validity index of each item was 0.941~1.000. Exploratory factor analysis extracted 5 common factors,and the cumulative variance contribution rate was 77.390%. There was a positive correlation between each factor and the total scale,the correlation coefficient was 0.580~0.857;the correlation coefficient between the total scale and the Inflammatory Bowel Disease Questionnaire was 0.925. The Cronbach’s alpha coefficient of the total scale was 0.900,and the test-retest reliability was 0.856. Conclusion The Symptom Cluster Scale for Inflammatory Bowel Disease has good reliability and validity,which can guide medical staff to comprehensively and accurately evaluate patients and provide evidence to develop individualized symptom management measures for patients with inflammatory bowel disease.
