The Connor-Davidson Resilience Scale's (CD-RISC) 10 item variant has previously demonstrated acceptable psychometric properties of its test scores using traditional methods (e.g., confirmatory factor analysis), and concurrent validity with resilience-related outcomes, particularly in samples of younger adults. While alternative methods of examining the psychometric properties of the long-form CD-RISC exist in the literature, the short-form measure has unclear evidence of local item independence and a unidimensional structure, which are key assumptions of a polytomous Rasch model approach to examining the measure's psychometric properties. The current study employed a sample of young adult university students (n = 708, xage = 26.43 years (s = 7.77)) on their nursing practicum placements to examine the CD-RISC-10 against the polytomous Rasch measurement model criteria. The analyses suggested a seven-item variant of the CD-RISC-10 performed acceptably, and omitted issues with local item dependence and item misfit. Effect sizes of the standardized parameters estimated for the 7-item and original 10-item versions of the CD-RISC-10, when predicting compassion fatigue and compassion satisfaction, were small (s = -0.24, s = -0.23) and moderate (s = 0.48, s = 0.47) for the respective measures, which suggested similar efficacy when examining the test scores' concurrent validity. The shorter version of the CD-RISC-10 consequently demonstrated generally acceptable psychometric properties for its test scores, and remained a parsimonious approach to examining individual psychological resilience that will benefit from further development.

使用多分 Rasch 模型检查 Connor-Davidson Resilience Scale 10 (CD-RISC-10)。

Connor-Davidson 弹性量表 (CD-RISC) 的 10 项变体先前已使用传统方法（例如验证性因素分析）证明其测试分数具有可接受的心理测量特性，以及与弹性相关结果的同时有效性，尤其是在年轻人样本中. 虽然文献中存在检查长格式 CD-RISC 的心理测量特性的替代方法，但短格式度量没有明确的局部项目独立性和一维结构的证据，这是多分 Rasch 模型方法检查的关键假设测量的心理测量特性。当前的研究采用了年轻的成年大学生样本（n = 708，xage = 26.43 岁（s = 7. 77)) 关于他们的护理实习安排，以根据多分 Rasch 测量模型标准检查 CD-RISC-10。分析表明，CD-RISC-10 的七项变体表现可以接受，并忽略了局部项依赖和项不匹配的问题。在预测同情疲劳和同情满意度时，CD-RISC-10 的 7 项和原始 10 项版本估计的标准化参数的影响大小较小（s = -0.24，s = -0.23）和中等（ s = 0.48, s = 0.47) 用于相应的测量，这表明在检查测试分数的并发有效性时具有相似的功效。因此，较短版本的 CD-RISC-10 的测试分数显示出普遍可接受的心理测量特性，并且仍然是一种简洁的方法来检查将受益于进一步发展的个人心理弹性。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
