Personality predicts how we interact with others, what partners we have, and how happy and lasting our romantic relationships are. At the same time, our experiences in these relationships may affect our personality. Who experiences specific major relationship events, and how do these events relate to personality development? We examined this issue based on data from a nationally representative household panel study from Germany (N = 49,932). In this study, the occurrence of major relationship events (moving in with a partner, marriage, separation, and divorce) was assessed yearly, and the Big Five personality traits were measured repeatedly in 2005, 2009, 2013, and 2017 with the short version of the Big Five Inventory. We applied multilevel analyses to simultaneously model selection effects as well as different types of personality changes in the years before and after these events in the total sample and separately in women and men. Our findings revealed that less agreeable individuals were more likely to experience each of the examined relationship events. Moreover, each event was associated with personality changes, which only occurred after (not before) these events and considerably varied by event and gender. Individuals who moved in with a partner, got married, or separated from a partner primarily experienced changes in openness in the first year thereafter, and individuals who separated from a partner or got divorced became less emotionally stable in the following years. However, there was little evidence for "maturation" effects, except that individuals who moved in with a partner (especially men) became more conscientious in the following years.

在爱情的过山车上经历起起落落：浪漫关系领域的重大生活事件与大五人格特质之间的关联。

性格预测我们如何与他人互动，我们有哪些伴侣，以及我们的浪漫关系有多幸福和持久。同时，我们在这些关系中的经历可能会影响我们的个性。谁经历了特定的重大关系事件，这些事件与人格发展有何关联？我们根据来自德国（N = 49,932）的具有全国代表性的家庭小组研究的数据研究了这个问题。在这项研究中，每年都会评估重大关系事件（与伴侣同居、结婚、分居和离婚）的发生情况，并在 2005 年、2009 年、2013 年和 2017 年以简短版本重复测量大五人格特质大五清单。我们应用多级分析同时模拟了选择效应以及这些事件前后几年中总样本以及女性和男性中不同类型的人格变化。我们的研究结果表明，不太讨人喜欢的人更有可能经历每一个检查过的关系事件。此外，每个事件都与性格变化有关，这种变化只发生在这些事件之后（而不是之前），并且因事件和性别而异。与伴侣同住、结婚或与伴侣分居的人在此后的第一年主要经历了开放性的变化，而与伴侣分居或离婚的人在接下来的几年中情绪变得不太稳定。然而，几乎没有证据表明“成熟”效应，除了与伴侣（尤其是男性）同住的人在接下来的几年里变得更加认真。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
