炎症性肠病病人自我管理行为量表的编制及信效度检验

Development and reliability and validity test of self-management behavior scale for patients with inflammatory bowel disease

[目的]编制可客观评价炎症性肠病病人自我管理行为的量表,并进行信效度检验。[方法]通过文献回顾、半结构式访谈、专家咨询及小样本预调查形成炎症性肠病病人自我管理行为量表初稿。选取江苏省3所三级甲等医院160例炎症性肠病病人进行调查,并进行信效度检验,形成最终量表。[结果]最终确定的炎症性肠病病人自我管理行为量表包括用药管理、饮食管理、疾病监测、情绪管理、运动管理、日常生活管理、资源利用7个维度,共36个条目,量表的总体Cronbach's α系数为0.945,各维度Cronbach's α系数分别为0.788,0.864,0.722,0.872,0.804,0.805,0.741,折半信度为0.810,重测信度为0.929,各维度重测信度为0.722~0.891;总量表的内容效度指数为0.926;校标关联效度为0.689;探索性因子分析提取7个公因子,累计贡献率为62.809%。[结论]构建的炎症性肠病病人自我管理行为量表信效度良好,可作为临床评估炎症性肠病病人自我管理行为的有效工具。

Objective:To develop a self-management behavior scale for patients with inflammatory bowel disease (IBD) and test its reliability and validity.Methods:Literature review,semi-structured interviews,expert consultations,and small sample pretest were used to identify the draft of the scale.A total of 160 IBD patients were investigated in three Tertiary Grade A hospitals in Jiangsu province.And the reliability and validity of scale were tested,then the final scale was developed.Results:The final self-administered behavior scale for patients with IBD included 36 items in 7 dimensions: medication management,diet management,disease monitoring,emotion management,exercise management,daily life management,and resource utilization.The total scale's Cronbach's α coefficient was 0.945,and each dimension's Cronbach's α coefficient was 0.788,0.864,0.722,0.872,0.804,0.805,and 0.741.The split-half coefficient was 0.810. The total scale's test-retest coefficient was 0.929,and each dimension's test-retest coefficient ranged from 0.722 to 0.891.The content validity index was 0.926 and the criterion validity coefficient was 0.689.The exploratory factor analysis extracted 7 common factors,and the cumulative contribution rate was 62.809%.Conclusion:The self-management behavior scale was proved to be reliable and valid, and it could be used as an effective tool for clinical evaluation of self-management behavior of IBD patients.
