【摘要】 目的 对心脏介入专科护士核心能力自评问卷进行信效度检验。方法 应用心脏介入专科护士核心能力自评问卷，于2022年11月，在全国范围内对534名心脏介入专科护士进行测评，并分析问卷的信效度。结果 心脏介入专科护士核心能力自评问卷包括5个维度45个条目。探索性因子分析累计方差贡献率为71.447%，各条目在所属维度上的因子载荷为0.538～0.856。验证性因子分析显示，修正后卡方/自由度为2.683，比较拟合指数为0.901，非规准适配度指数为0.889。问卷总的Cronbach’s α系数为0.973，折半信度为0.922；各维度的Cronbach’s α系数为0.844～0.964，折半信度为0.780～0.946，重测信度为0.789～1.000。结论 心脏介入专科护士核心能力自评问卷具有较好的信效度，可用于心脏介入专科护士核心能力的自评，并为护理管理者进行人力资源配置提供参考。更多还原

【Abstract】 Objective To test the reliability and validity of a self-rating core competence questionnaire for cardiac intervention nurses. Methods In November 2022, 534 cardiac intervention nurses nationwide were assessed with the self-rating core competence questionnaire, and subsequent analysis was conducted to test the reliability and validity of the questionnaire.Results The self-rating core competence questionnaire for cardiac intervention nurses was composed of 45 items in 5 dimensions.Exploratory factor analysis revealed that the cumulative variance contribution rate was 71.447% and the factor loading of each item in the corresponding dimension was 0.538-0.856. Confirmatory factor analysis showed that the modified ratio of chi-square/degree of freedom was 2.683, the comparative fit index was 0.901 and the non-normed fit index was 0.889. For the questionnaire as a whole, the Cronbach’s alpha was 0.973 and the split-half reliability was 0.922; for each dimension, the Cronbach’s alpha was 0.844-0.964, the split-half reliability was 0.780-0.946 and the test-retest reliability was 0.681-1.000.Conclusion The self-rating core competence questionnaire for cardiac intervention nurses exhibits robust reliability and validity. It is suitable for the self-rating of core competence in cardiac intervention nurses and serves as a valuable tool for nurse administrators in optimizing human resource allocation.更多还原
