目的：研制脑卒中患者家属对卒中复发应急能力评估量表，并检验其信效度。方法：采用文献回顾法、 半结构访谈法和两轮德尔菲专家函询法构建初始量表，通过对西安市3所三甲医院脑卒中患者家属进行问 卷调查，对量表进行条目筛选、效度和信度检验。结果：最终量表共5个维度35个条目，总的Cronbach's α系 数为0.882，分半信度系数为0.851，量表的内容效度（S-CVI）为0.935。探索性因子分析（EFA）共提取10个 特征值大于 1的公因子，分属于5个维度，累积方差贡献率为63.792%，提取的公因子与预先根据理论框架 设计的结构假设相符，量表各维度与总分的Pearson相关系数为0.455～0.867。结论：该量表研制过程科学 严谨，具有良好的信效度，可有效测评脑卒中患者家属对卒中复发的应急能力。

To develop an assessment scale for the stroke recurrence emergency response ability of family members of stroke patients, and to test its reliability and validity. Methods: The initial draft of the scale was formulated based on literature review, semi-structured interview, and two-round expert consultation using the Delphi technique. By conducting a questionnaire survey on the family members of stroke patients in 3 tertiary hospitals in Xi'an, the item selection, validity, and reliability of the scale were evaluated. Results: The final questionnaire included 35 items in 5 dimensions. The total Cronbach's α coefficient was 0.882, the split-half reliability coefficient was 0.851, and the total content validity (S?CVI) was 0.935. Exploratory factor analysis (EFA) extracted 10 common factors with eigenvalues greater than 1, which belonged to 5 dimensions. The cumulative variance contribution rate was 63.792% , and the 10 factors were consistent with the preliminary design. Pearson's correlation coefficient between all factors and the total scale score was 0.455～0.867. Conclusion: The development process of the scale was scientific and rigorous. The scale exhibits good reliability and validity, and it can effectively evaluate the emergency response ability of stroke patients' family members to stroke recurrence.
