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’s α系数为 0.885，各维度 Cronbach’s α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。

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’s α coefficients 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.
