(a)采用探索性因子分析（EFA）和验证性因子分析（CFA）研究危重病护士康诺-戴维森弹性量表（CD-RISC）的因子结构；(b)评估CD-RISC在危重病护士中的信度和已知组间差异。CD-RISC调查收集了全美国744名重症护理护士。CD-RISC的精简版本用于EFA和CFA。进一步的可靠性和已知的组差异也进行了测试。EFA识别出3个特征值为bbb1.0的因子，解释方差为59%。这些因素被标记为个人能力、毅力和领导力，每个因素都有显著的负荷。三因素CFA对数据拟合良好，χ2 = 243.1, p < .001；Rmsea = .062；CFI = .935，但3个因素之间的相关性较高（.78 ~ .86）。随后对1因素模型进行了测试，但没有产生更好的拟合，模型比较分析支持保留3因素模型。诊断为创伤后应激障碍（PTSD）的重症监护病房（ICU）护士的总心理弹性得分（M = 75.43）显著低于未诊断为创伤后应激障碍的护士（M = 83.21; t = 5.01; p < .001）。目前的调查发现，3因素结构最适合于ICU护士人群中CD-RISC精简版的数据。分析还支持了16项测量的可靠性和已知组差异。需要进一步的研究来检查与这一人群有关的恢复力的特征和能力特征。
(a) To investigate the factor structure of the Connor-Davidson Resilience Scale (CD-RISC) in critical care nurses, using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) and (b) to assess reliability and known group differences of the CD-RISC on critical care nurses. CD-RISC surveys were collected on 744 critical care nurses across the United States. An abridged version of the CD-RISC was used for the EFA and CFA. Further reliability and known group differences were also tested. EFA identified 3 factors with eigenvalues >1.0 and an explained variance of 59%. The factors were labeled personal competence, perseverance, and leadership, and each factor had salient loadings. The 3-factor CFA provided good fit to the data, χ2 = 243.1, p < .001; RMSEA = .062; CFI = .935, although correlations among the 3 factors were high (.78–.86). A 1-factor model was subsequently tested but did not produce a better fit, and model comparison analyses supported retention of the 3-factor model. Known group differences was supported as intensive care unit (ICU) nurses with a diagnosis of posttraumatic stress disorder (PTSD) had significantly lower total resilience scores (M = 75.43) compared to those without a diagnosis of PTSD (M = 83.21; t = 5.01; p < .001). The current investigation found that the 3-factor structure provided the best fit for the data on the abridged version of the CD-RISC in a population of ICU nurses. Analyses also supported the reliability and known group differences of the 16-item measure. Further research is needed to examine trait and capacity features of resilience as it relates to this population.
