Empathy is an important social construct that has been defined in many ways by different authors, resulting in development of several questionnaires. The Interpersonal Reactivity Index (IRI) is one of the most used self-report scales to measure empathy in children, adolescents, and adults. However, studies have reported contradictory results about its factor structure. Therefore, the aim of the current study was to assess the dimensionality of the IRI through a meta-analytic structural equation modeling approach (MASEM). Eleven studies (total n = 9470) were included in the MASEM. The meta-analytic confirmatory factor analyses (CFAs) provided support for four of the tested models. A comparison of these models showed that the four-factor model proposed by Lucas-Molina et al. (2017) had the best fit. Overall, this MASEM suggests that the IRI provides a multidimensional, rather than a unidimensional, measurement of the empathy construct.

同理心是一种重要的社会结构，不同的作者以多种方式定义了它，从而开发了一些调查问卷。人际反应指数 (IRI) 是最常用的自我报告量表之一，用于衡量儿童、青少年和成人的同理心。然而，关于其因素结构的研究报告了相互矛盾的结果。因此，当前研究的目的是通过元分析结构方程建模方法（MASEM）评估 IRI 的维数。MASEM 中纳入了 11 项研究（总计 n = 9470）。荟萃分析验证性因素分析 (CFA) 为四个测试模型提供了支持。这些模型的比较表明 Lucas-Molina 等人提出的四因素模型。(2017) 是最合适的。总体而言，该 MASEM 表明 IRI 提供了多维而非单维的同理心构建测量。
