下肢外周动脉疾病患者自我管理量表的编制及信效度检验

Compilation of Self-management Scale for Patients with Lower Extremity Peripheral Artery Disease and its reliability and validity test

目的:基于慢性病自我管理项目(CDSMP)编制下肢外周动脉疾病患者自我管理量表,并检验其信效度。方法:以CDSMP为理论框架,通过文献回顾、课题组讨论、半结构式访谈、德尔菲专家函询形成量表。采用便利抽样法,于2021年10月—2022年3月选取华中科技大学同济医学院附属协和医院血管外科病房的200例下肢外周动脉疾病患者进行调查,以检验量表的信效度。共发放200份调查问卷,回收有效问卷183份,问卷有效回收率为91.50%。结果:量表总体的Cronbach'sα系数为0.935;量表条目水平的内容效度指数为0.825~1.000,量表水平的内容效度指数为0.964;未限定因子个数进行第1次探索性因子分析,得到5个公因子,累积方差贡献率为82.330%,根据碎石图限定提取4个公因子,进行第2次探索性因子分析,累积方差贡献率为78.856%。经过筛选最终形成的正式量表包含4个维度、26个条目。结论:下肢外周动脉疾病患者自我管理量表具有较好的信效度,可作为护理人员调查下肢外周动脉疾病患者自我管理水平的工具。

Objective To develop the Self-management Scale for Patients with Lower Extremity Peripheral Artery Disease based on Chronic Disease Self-Management Program(CDSMP)and test its reliability and validity.Methods Using CDSMP as the theoretical framework,a scale was formed through literature review,research group discussions,semi-structured interviews and Delphi expert inquiries.From October 2021 to March 2022,a total of 200 patients with lower extremity peripheral artery disease in the ward of Department of the Vascular Surgery,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology were investigated by the convenient sampling to test the reliability and validity of the scale.A total of 200 questionnaires were distributed,and 183 valid questionnaires were recovered,with an effective recovery rate of 91.50%.Results Cronbach'sαcoefficient of the overall scale was 0.935;the content validity indexes at the item level of the scale were 0.825-1.000,the content validity index at the scale level was 0.964.The first exploratory factor analysis was conducted without limiting the number of factors,and 5 common factors were obtained,with a cumulative variance contribution rate of 82.330%.According to the gravel map,4 common factors were limited and extracted from the second exploratory factor analysis,with a cumulative variance contribution rate of 78.856%.The formal scale formed after screening included 4 dimensions and 26 items.Conclusions The Self-management Scale for Patients with Lower Extremity Peripheral Artery Disease has good reliability and validity,which can be used as a tool for nursing staff to investigate the self-management level of patients with lower extremity peripheral arterial disease.
