Erikson's psychosocial stage model posits that identity formation is a key developmental task for adolescents, and that successfully resolving the identity versus role confusion crisis at this time of life has important impacts on psychosocial development through adulthood. However, little empirical work has tested the consequences of early-life identity development for progression through the subsequent psychosocial stages in Erikson's model. The purpose of the present study was to test whether identity resolution measured during emerging adulthood predicted later developmental trajectories of intimacy, generativity, and integrity across adulthood. We used data from four cohorts of participants in the Rochester Adult Longitudinal Study (RALS; N = 1,224), with up to five assessments spanning the twenties through the sixties. Latent growth curve modeling was used to estimate developmental trajectories for intimacy, generativity, and integrity, and to test the association between emerging adulthood identity resolution and growth parameters for each psychosocial outcome. Findings suggested that individuals with higher emerging adulthood identity resolution also experienced high levels of intimacy, generativity, and integrity in emerging adulthood, and these levels remained consistently high across adulthood. In contrast, those with lower identity resolution in emerging adulthood experienced lower initial levels of intimacy, generativity, and integrity, but faster growth over time. As a result, these trajectories appeared to nearly converge by the time participants were in their sixties, suggesting that one's emerging adulthood identity has less importance over time, and that individuals who struggled more with identity formation in adolescence and emerging adulthood are able to make up for it later in life.

身份解析在成年期对整个成年期的亲密感、生殖力和完整性的影响。

埃里克森的心理社会阶段模型认为，身份形成是青少年的一项关键发展任务，成功解决人生这个时期的身份与角色混淆危机对成年后的心理社会发展具有重要影响。然而，很少有实证研究测试了早期身份发展对埃里克森模型中后续社会心理阶段进展的影响。本研究的目的是测试在成年期测量的身份分辨是否能预测成年后的亲密、生殖和完整性的发展轨迹。我们使用了来自罗彻斯特成人纵向研究 (RALS；N = 1,224) 的四组参与者的数据，在 20 到 60 年代进行了多达五次评估。潜在生长曲线模型用于估计亲密性、生殖力和完整性的发展轨迹，并测试新兴成年身份分辨率与每个心理社会结果的生长参数之间的关联。研究结果表明，具有较高新兴成年身份分辨率的个体在成年后也经历了高水平的亲密性、生殖力和完整性，并且这些水平在整个成年期始终保持较高水平。相比之下，那些在成年后身份分辨率较低的人的初始亲密度、创造力和完整性水平较低，但随着时间的推移增长速度更快。结果，这些轨迹似乎在参与者 60 岁时几乎收敛，这表明随着时间的推移，一个人的成年身份变得不那么重要了，并且那些在青春期和成年期更难以形成身份认同的人能够在以后的生活中弥补这一点。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
