糖尿病足患者出院准备度量表的编制及信效度检验

Development and reliability and validity of a Discharge Preparation Scale for Diabetic Foot Patients

目的基于信息-知识-信念-行为(Information-Knowledge-Attitude-Practice,IKAP)理论编制符合国情及疾病特点的糖尿病足患者出院准备度量表并检验其信效度。方法依据IKAP理论框架,通过文献分析、质性访谈、专家函询法确立量表条目,经过预调查后,选取2023年6月—2024年2月在江西省3所三级甲等综合医院住院治疗的483例糖尿病足患者作为调查对象,采用项目分析法筛选条目,并进行信效度检验。结果糖尿病足患者出院准备度量表包含4个维度、29个条目。量表总的Cronbach’sα系数为0.934,各维度的Cronbach’sα系数为0.889~0.947;量表总的折半信度为0.966,各维度的折半信度为0.901~0.952。探索性因子分析提取4个公因子,累计方差贡献率为68.074%;验证性因子分析χ^(2)/df值为1.906,模型拟合配适度符合要求。量表水平的内容效度为0.973,条目水平的内容效度为0.875~1.000。结论糖尿病足患者出院准备度量表的信度、效度均较好,可以作为评估糖尿病足患者出院准备度的工具。

Objective Based on the theory of Information-Knowledge-Attitude-Practice(IKAP),the reliability and validity of the discharge preparation scale for patients with diabetic foot(DF)was developed and tested,which is in accordance with the national conditions and disease characteristics of our country.Methods Based on the IKAP theoretical framework,articles were identified through literature analysis,qualitative interviews and Delphi method.After pre-investigation,a total of 483 patients with DF were selected from 3 general hospitals in Jiangxi province from June 2023 to February 2024.The items were screened by item analysis,and the reliability and validity were tested.Results The discharge preparation scale for patients with DF included 4 dimensions and 29 items.The Cronbach’sαcoefficient was 0.934;the scores of each dimension Cronbach’sαcoefficient ranged from 0.889 to 0.947;the overall split-half reliability was 0.966,and the split-half reliability of each dimension ranged from 0.901 to 0.952.A total of 4 common factors were extracted by exploratory factor analysis,and the cumulative contribution rate of variance was 68.074%.Theχ^(2)/df value of confirmatory factor analysis was 1.906.The fitting fit of the model is suitable.The content validity was 0.973 at scale level and 0.875~1.000 at item level.Conclusion The reliability and validity of the discharge preparation scale for patients with DF are good,and it can be used as a tool to evaluate the discharge preparation for patients with DF.
