目的 编制主动脉夹层术后患者症状群评估量表并进行信效度检验，为相关患者提供客观有效的评估工具。 方法 以症状管理模型为基础，通过文献回顾、半结构访谈构建条目池，经2轮德尔菲专家函询及预调查形成初稿。2023年9月至2024年7月，以便利抽样法选取在南京市某三级甲等医院心脏外科治疗的主动脉夹层术后患者492例为研究对象进行调查，以检验量表信效度。结果 主动脉夹层术后患者症状群评估量表包括5个维度，共27个条目。量表的Cronbach’s α系数为0.940，折半信度为0.826，重测信度为0.917，量表内容效度为0.877。探索性因子分析共提取出5个公因子，累计方差贡献率为71.859%；验证性因子分析显示:卡方自由度比（χ²/df）为2.121，近似误差均方根(root mean square error of approximation,RMSEA)为0.066，非规范拟合指数(Tucker-Lewis index,TLI)为0.923、增量拟合指数(incremental fit index,IFI)为0.931、比较拟合指数(comparative fix index,CFI)为0.931，模型拟合良好。结论 主动脉夹层术后患者症状群评估量表具有良好的信效度，可作为主动脉夹层术后患者症状群评估的有效工具。

Objective To develop and assess the reliability and validity of a symptom cluster assessment scale for postoperative aortic dissection patients，and to provide objective and effective assessment tools for relevant patients.Methods Based on the symptom management model，an item pool was constructed through literature review and semi-structured interviews.After two rounds of Delphi expert inquiries and pre-investigations，the first draft was finally formed.From September 2023 to July 2024，492 patients who had undergone aortic dissection surgery in the Cardiac Surgery Department of a tertiary A hospital in Nanjing were selected by the convenience sampling method and investigated to test the reliability and validity of the scale.Results The symptom cluster assessment scale for postoperative aortic dissection patients consisted of 5 dimensions and 27 items.The Cronbach’s α coefficient of the scale was 0.940，the split-half reliability was 0.826，the test-retest reliability was 0.917，and the content validity of the scale was 0.877.Exploratory factor analysis extracted 5 common factors，and the cumulative variance contribution rate was 71.859%.Confirmatory factor analysis showed that the chi-square ratio of degrees of freedom (χ²/df) was 2.121 and the root mean square error of approximation (RMSEA) was 0.066.The Tucker-Lewis index (TLI) was 0.923，the incremental fit index (IFI) was 0.931，and the comparative fix index (CFI) was 0.931.The model fit well.Conclusions The symptom cluster assessment scale for postoperative aortic dissection patients demonstrates good reliability and validity，which can be used as an effective tool for evaluating symptom clusters in patients after aortic dissection surgery.
