ObjectiveSeveral recent accounts have failed to replicate the so‐called Narcissism Epidemic, suggesting potential influences of the Global Financial Crisis (GFC) in 2008 as a reason for narcissism trend reversals. Here, we provide evidence for narcissism test score changes from 1982 to 2023.MethodsWe investigated self‐report data on the Narcissistic Personality Inventory (NPI) from 1105 studies (k = 1621, N = 546,225) using precision‐weighted cross‐temporal meta‐analysis.ResultsData collection years were meaningfully negatively associated with narcissism scores in virtually all analyses (bs: −0.409 to −0.008; partial eta square's: < 0.001 to 0.118; ps: < 0.001 to 0.174), thus indicating cross‐temporally decreasing narcissism self‐report scores. Examination of regression segments pre‐ and post‐dating the GFC and segmented line regressions indicated mostly stable narcissism scores during the 1980s and 1990s that subsequently showed negative slopes with somewhat differing decreases onsets according to analytical subsets.ConclusionsHere, we provide evidence for negative cross‐temporal changes in narcissism from 1982 to 2023 globally, thus contrasting the idea of a Narcissism Epidemic having taken place at any point during the past four decades. Changes appear to generalize across different regions and participant sex, although mean scores were differentiated, yielding higher narcissism values for North American and younger samples.

告别自恋流行病？全球 NPI 分数的跨时间荟萃分析 （1982-2023）


目标最近的几个账户未能复制所谓的自恋流行病，这表明 2008 年全球金融危机 （GFC） 的潜在影响是自恋趋势逆转的原因。在这里，我们提供了 1982 年至 2023 年自恋测试分数变化的证据.方法我们使用精密加权跨时间荟萃分析调查了 1105 项研究（k = 1621，N = 546,225）中关于自恋人格量表 （NPI） 的自我报告数据。结果在几乎所有分析中，数据收集年份都与自恋分数有意义地呈负相关（bs：-0.409 至 -0.008;部分 eta 平方：< 0.001 至 0.118;ps：< 0.001 至 0.174），因此表明自恋自我报告分数跨时间递减。对 GFC 前后回归片段的检查和分段线回归表明，在 1980 年代和 1990 年代，自恋分数大多稳定，随后显示负斜率，根据分析子集，开始的减少程度略有不同。结论在这里，我们为 1982 年至 2023 年全球自恋的负面跨时间变化提供了证据，从而对比了过去四十年中任何时候发生的自恋流行病的想法。变化似乎在不同地区和参与者性别之间普遍存在，尽管平均分数存在差异，因此北美和年轻样本的自恋值更高。
