The resilience construct is considered a personal trait composed of multiple aspects. Connor-Davidson Resilience Scale is a standard tool composed of five factors and 25 items. This study aimed to determine the psychometric properties of this scale.
In this cross-sectional study, after the scale translation, the factorial structural validity was assessed via the confirmatory factor analysis with 70 180 samples. Internal consistency, composite reliability, convergent validity were assessed by calculating Cronbach's alpha, composite reliability, maximum reliability, and Average Variance Extracted. The discriminant validity was assessed using Heterotrait-monotrait ratio of correlations matrix and also, measure invariance was evaluated.
The original five-factor model had good model fit indices but due to low factor loading of item 2 and 20, the model was modified. The Cronbach's alpha and composite reliability for four factors were above 0.7 (except for factor 5). The convergent validity for all five factors were achieved. Between factors 1 with 2 and 4, 2 with 3 and 4 discriminant validity was not established (correlations > 0.9) and the results suggested that there might be a second-order latent construct behind these factors. Therefore, a second-order assessment was performed. The results of the second-order latent construct assessment showed a good goodness-of fit and strong measurement invariance for both men and women.
The 23-item version of Connor-Davidson Resilience Scale is a reliable and valid scale to measure resilience as a complex construct in the Iran context.
弹性结构被认为是由多个方面组成的个人特质。Connor-Davidson 弹性量表是一种由五个因素和 25 个项目组成的标准工具。本研究旨在确定该量表的心理测量特性。
在这项横断面研究中，在对量表进行翻译后，使用 70180 个样本进行验证性因子分析来评估其因子结构的有效性。通过计算 Cronbach's alpha、综合可靠性、最大可靠性和平均方差提取来评估内部一致性、综合可靠性、收敛有效性。使用异质单特质相关矩阵评估判别有效性，并评估度量不变性。
最初的五因素模型具有良好的模型拟合指数，但由于项目 2 和 20 的因子负荷较低，因此对模型进行了修改。四个因素的 Cronbach's alpha 和综合可靠性均高于 0.7（除了第五个因素）。所有五个因素的收敛有效性均得到了实现。在因素 1 与 2 和 4 之间，2 与 3 和 4 之间没有建立判别有效性（相关系数>0.9），结果表明这些因素背后可能存在二阶潜在结构。因此，进行了二阶评估。二阶潜在结构评估的结果表明，对于男性和女性，二阶潜结构评估具有良好的拟合优度和强测量不变性。
23 项 Connor-Davidson 弹性量表是一种可靠且有效的量表，可用于衡量伊朗背景下作为复杂结构的弹性。
