Nostalgia, a sentimental longing or wistful affection for the past, confers self‐oriented, existential, and social benefits. We examined whether nostalgic engagement is less beneficial for individuals who are high in neuroticism (i.e. emotionally unstable and prone to negative affect). Specifically, we tested whether the benefits of experimentally induced nostalgia are moderated by trait‐level neuroticism. To address this issue, we conducted a high‐powered individual participant data meta‐analysis (N = 3556, k = 19). We found that the benefits of nostalgia were not significantly moderated by neuroticism, as they emerged for both high and low neurotics. This finding upheld when the self‐oriented, existential, and social benefits of nostalgia were analysed jointly and when they were analysed separately. Taken together, individuals high and low in neuroticism are equally likely to benefit psychologically from engagement in nostalgic reverie. © 2020 The Authors.

神经质会破坏怀旧的心理益处吗？荟萃分析测试

怀旧，一种对过去的情感渴望或渴望，赋予了自我导向，存在和社会利益。我们研究了怀旧的参与是否对神经质较高的人（即情绪不稳定且易于产生负面影响）的益处较小。具体来说，我们测试了特质水平的神经质是否减轻了实验性怀旧的益处。为了解决这个问题，我们进行了功能强大的个人参与者数据荟萃分析（N  = 3556，k = 19）。我们发现，怀旧的好处并没有因神经质而明显减弱，因为它们出现在高级和低级神经病中。当对怀旧的自我导向的，存在的和社会的利益进行联合分析以及对它们分别进行分析时，这一发现将得到支持。综上所述，神经质高低的人同样有可能从参与怀旧遐想的心理上受益。©2020作者。John Wiley＆Sons Ltd代表欧洲人格心理学协会出版的《欧洲人格杂志》
