This study presents the adaptation of the Uncertainty Response Scale (Greco & Roger, Pers. Individ. Differ, 31:519-534, 2001) to Portuguese. This instrument was administered to a non-clinical community sample composed of 1596 students and professionals, allowing a thorough validity and invariance analysis by randomly dividing participants into three subsamples to perform: an exploratory factor analysis (sample one: N = 512); a preliminary confirmatory factor analysis to identify the final solution for the scale (sample two: N = 543); and the confirmatory factor analysis (sample three: N = 541). Samples two and three were also used for multi-group analysis to assess measurement invariance, invariance across gender, sociocultural levels, and students versus active professionals. Results showed the scale reflects the original factorial structure, as well as good internal consistency and overall good psychometric qualities. Invariance results across groups reached structural invariance which provides a confident invariance measurement for this scale, while invariance across gender and sociocultural levels reached metric invariance. Accordingly, differences between these groups were explored, by comparing means with multi-group analysis to establish the scale’s sensitivity toward social vulnerability, by demonstrating the existence of statistically significant differences regarding gender and sociocultural levels on how individuals cope with uncertainty, specifically in terms of emotional strategies, as a self-defeating strategy. Thus, females scored higher on emotional uncertainty, as well as low sociocultural levels, compared with higher ones. Therefore, it is proposed that this scale could be a sound alternative to explore strategies for coping with uncertainty, when considering social, economic, or other environmental circumstances that may affect them.

不确定性反应量表的因式有效性和度量不变性

这项研究提出了不确定性反应量表（Greco和Roger，Pers。Individ。Differ，31：519-534，2001）对葡萄牙语的适应性。该仪器被用于由1596名学生和专业人员组成的非临床社区样本，通过将参与者随机分为三个子样本进行彻底的有效性和不变性分析：探索性因素分析（样本一：N = 512）；初步的验证性因子分析，以确定量表的最终解决方案（样本二：N = 543）；以及确认因子分析（样本三：N = 541）。样本二和样本三也用于多组分析，以评估测量的不变性，性别，社会文化水平以及学生与活跃专业人员之间的不变性。结果显示该量表反映了原始阶乘结构，以及良好的内部一致性和整体良好的心理素质。群体间的不变性结果达到结构不变性，这为该量表提供了一个有信心的不变性度量，而性别和社会文化水平之间的不变性达到了度量不变性。因此，通过比较手段和多组分析以建立量表对社会脆弱性的敏感性，并通过证明在性别和社会文化水平上存在关于个体如何应对不确定性的统计学上显着差异，特别是在不确定性方面，探讨了这些群体之间的差异。情绪策略，作为一种自欺欺人的策略。因此，与较高的女性相比，女性在情绪不确定性和较低的社会文化水平上得分较高。因此，
