家属决策冲突量表在神经内科ICU患者家属中应用的信效度检验

Reliability and Validity of Decisional Conflict Scale in Family of Neurology ICU Patients

目的:编制家属决策冲突量表,并在神经内科ICU患者家属中对其进行信效度检验。方法:基于患者决策冲突量表(DCS),编制家属决策冲突量表,抽取神经内科ICU 191例患者家属进行问卷调查,检验其信效度。结果:家属决策冲突量表共16个条目,因子分析共提取3个公因子,累计贡献率达到68.024%。量表水平的内容效度为0.990,Cronbach’sα系数为0.885,各维度Cronbach’sα系数分别为0.802、0.861、0.924,Guttman折半系数为0.727。结论:家属决策冲突量表具有良好的信效度,适用于评估神经内科ICU患者家属的决策冲突水平。

Objective:To develop the family Decisional Conflict Scale(DCS)and test its reliability and validity in the family of neurology ICU inpatients.Methods:The family Decisional Conflict Scale was developed based on the patient Decisional Conflict Scale.Total 191 family members of neurology ICU inpatients were enrolled to test the reliability and validity.Results:The family-DCS consisted of 16 items.Factor analysis extracted 3 common factors,and the cumulative contribution rate reached 68.024%.The content validity index was 0.990.The Cronbach’sαcoefficients of the total scale was 0.885,and that of the 3 factors were 0.802,0.861,and 0.924,respectively.The Guttman split-half reliability was 0.727.Conclusion:The family DCS has good reliability and validity,which can be useful for assessing decisional conflict level in the family of neurology ICU inpatients.
