Research in personality trait change has largely relied on mean-level and rank-order change across the lifespan. The current research expanded the literature in several ways: analyzing four types of change and correlated change patterns, obtaining multi-informant reports, including lower-order personality traits, and collecting multiple assessments during a short yet important time for college-attending emerging adults (baseline N = 259, M_age = 18.79). There was little evidence for mean-level change, yet participants showed significant individual differences such that rank-ordering and ipsative profiles were much more dynamic than mean score patterns. Informant-reports from close others demonstrated largely similar patterns: little to no mean-level change, significant increase in rank-ordering, and about half of participants reporting configural change mostly in elevation and scatter rather than in profile shapes. Interestingly, there was no correlated change between self and other-reports. This indicated that close others do not share individuals' perception of their own personality trait change, at least not in the demographic group studied. By examining individual-level, sample-level, and multi-informant perspectives, our thorough investigation provided useful benchmarks for future research to examine the source of variability in change trajectories.

大学期间人格特质变化的四种变化和自我认同：多信息纵向研究

人格特质变化的研究在很大程度上依赖于整个生命周期的平均水平和等级顺序变化。目前的研究在几个方面扩展了文献：分析四种类型的变化和相关的变化模式，获得多信息报告，包括低阶人格特质，并在短暂但重要的时间内为正在上大学的新兴成年人收集多项评估（基线N  = 259，M_年龄 = 18.79）。几乎没有平均水平变化的证据，但参与者表现出显着的个体差异，因此排名顺序和比喻概况比平均得分模式更具动态性。来自亲密其他人的线人报告显示出大致相似的模式：几乎没有或没有平均水平变化，排名顺序显着增加，大约一半的参与者报告配置变化主要是海拔和散射而不是轮廓形状。有趣的是，自我报告和他人报告之间没有相关变化。这表明亲密的人不会分享个人对自己人格特质变化的看法，至少在所研究的人口群体中不会。通过检查个体水平、样本水平和多线人的观点，
