    • 摘要:
      目的 编制适用于我国脑卒中病人的疾病认知问卷并检验其信效度。
      方法 以知信行理论模式为理论框架，结合文献回顾法、半结构访谈法、专家函询和预调查形成初始问卷。采用便利抽样法，选取2022年6—8月就诊的260例脑卒中病人进行项目分析和信效度检验；选取2022年9—10月就诊的200例脑卒中病人进行验证性因子分析。
      结果 问卷具有良好的信效度。问卷总Cronbach's α系数为0.978，各维度Cronbach's α系数为0.866~0.985；总折半信度为0.785，各维度折半信度为0.865~0.974；总重测信度为0.960，各维度重测信度为0.924~0.948；问卷水平的内容效度指数为0.87，各条目水平的内容效度指数为0.80~1.00；KMO值为0.960，Bartlett's球形检验χ2值为17 239.25(P < 0.01)，二次旋转后提取出3个公因子，累计方差贡献率为78.748%；标准化载荷值为0.820~0.943(P < 0.01)；卡方自由度比值为2.457；近似误差均方根为0.086；增值拟合指数为0.903；比较拟合指数为0.903以及非规范拟合指数为0.898。
      结论 编制的脑卒中病人疾病认知问卷具有良好的信效度，可用于评估脑卒中病人的疾病认知水平，为临床评估脑卒中病人疾病认知水平提供科学测评工具。

       

      Abstract:
      Objective To develop a disease cognition questionnaire suitable for stroke patients in China and test its reliability and validity.
      Methods Using the knowledge, attitude, practice model as the theoretical framework, an initial questionnaire was formed by combining literature review, semi-structured interview, expert inquiry, and presurvey.Using convenience sampling method, 260 stroke patients from June to August 2022 were selected for item analysis and reliability and validity test; 200 stroke patients who visited the hospital from September to October 2022 were selected for confirmatory factor analysis.
      Results The questionnaire had good reliability and validity.The Cronbach's α coefficient of the questionnaire was 0.978, and the Cronbach's α coefficient of each dimension was 0.866-0.985;the split-half reliability was 0.785, and the split-half reliability of each dimension was 0.865-0.974;the test-retest reliability was 0.960, and the test-retest reliability of each dimension was 0.924-0.948;the scale-level content validity index (S-CVI) was 0.87, and the item-level content validity index (I-CVI) was 0.80-1.00;KMO value was 0.960, and χ2 value of Bartlett's sphericity test was 17 239.25 (P < 0.01).Three common factors were extracted after the second rotation, and the cumulative variance contribution rate was 78.748%.The standardized load value was 0.820-0.943 (P < 0.01), χ2/df was 2.457, RMSEA was 0.086, IFI was 0.903, CFI was 0.903, TLI was 0.898.
      Conclusions The developed disease cognition questionnaire for stroke patients has good reliability and validity, and can be used to evaluate the disease cognition level of stroke patients, providing a scientific evaluation tool for clinical evaluation of the disease cognition level of stroke patients.
