Are recent cohorts of college students more narcissistic than their predecessors? To address debates about the so-called "narcissism epidemic," we used data from three cohorts of students (1990s: N = 1,166; 2000s: N = 33,647; 2010s: N = 25,412) to test whether narcissism levels (overall and specific facets) have increased across generations. We also tested whether our measure, the Narcissistic Personality Inventory (NPI), showed measurement equivalence across the three cohorts, a critical analysis that had been overlooked in prior research. We found that several NPI items were not equivalent across cohorts. Models accounting for nonequivalence of these items indicated a small decline in overall narcissism levels from the 1990s to the 2010s ( d = -0.27). At the facet level, leadership ( d = -0.20), vanity ( d = -0.16), and entitlement ( d = -0.28) all showed decreases. Our results contradict the claim that recent cohorts of college students are more narcissistic than earlier generations of college students.
近年来的大学生群体比他们的前辈更自恋吗?为了解决所谓的“自恋流行病”的争论,我们使用了三批学生的数据(1990 年代:N = 1166;2000 年代:N = 33647;2010 年代:N = 25412)来检验自恋水平(总体和具体方面)是否在代际之间有所增加。我们还测试了我们的衡量标准,自恋人格量表(NPI),是否在三个队列中表现出测量等效性,这是之前研究中被忽视的关键分析。我们发现,NPI 的几个项目在不同队列之间并不等效。考虑到这些项目不等效的模型表明,从 1990 年代到 2010 年代,整体自恋水平略有下降(d = -0.27)。在方面层面上,领导力(d = -0.20)、虚荣(d = -0.16)和权利感(d = -0.28)都有所下降。我们的结果与最近的大学生群体比前几代大学生更自恋的说法相矛盾。
