Moral outrage (MO) is an emotional experience that arises in situations where a moral standard is violated. Despite its relevance, there are few psychometric studies in the Latin American context, characterized by inequality and social problems. This highlights the need for specific assessment instruments for this construct. The purpose of this study was to analyze the psychometric properties of an MO scale in the Peruvian population.
The sample consisted of 881 Peruvians (57.2% women, M = 24.5 years, SD = 9.07 years). The moral outrage scale was administered to participants. To analyze the data, two models were tested: a structural equation model (SEM) and an exploratory structural equation model (ESEM).
The CFA confirmed a two-factor model (emotional and cognitive), with satisfactory fit indices and standardized factor loadings greater than 0.70. The ESEM model also showed improved fit indices. Measurement invariance across sex was established, and convergent validity was demonstrated between the dimensions of MO and authoritarianism, as well as other sociodemographic variables such as sex, age, and socioeconomic level.
The MO scale tested in this study is a reliable, valid, and invariant instrument, suitable for assessing moral outrage in both men and women within the Peruvian context.
道德愤怒（MO）是一种在道德标准被违反的情况下产生的情绪体验。尽管它具有相关性，但在拉丁美洲背景下，这种情绪体验的心理测量研究很少，该地区的特点是不平等和社会问题。这突出了需要为这一结构制定特定的评估工具。本研究的目的是分析秘鲁人群中 MO 量表的心理测量特性。
样本由 881 名秘鲁人（57.2%女性，M=24.5 岁，SD=9.07 岁）组成。向参与者发放道德愤怒量表。为了分析数据，测试了两种模型：结构方程模型（SEM）和探索性结构方程模型（ESEM）。
验证性因素分析（CFA）证实了一个两因素模型（情绪和认知），具有令人满意的拟合指数和大于 0.70 的标准化因子负荷。ESEM 模型也显示出了改进的拟合指数。跨性别的测量不变性得到了确立，MO 的维度与威权主义以及其他社会人口变量（如性别、年龄和社会经济水平）之间表现出了良好的收敛效度。
本研究中测试的 MO 量表是一种可靠、有效的、不变的工具，适合在秘鲁的男女中评估道德愤怒。
