Personality and identity formation are intricately linked in adolescent development. The personality disposition of perfectionism has been associated with identity processes, but their longitudinal interplay in adolescence has not yet been investigated. This four-wave study, with 5- to 6-month intervals between each wave (N = 744 Caucasian adolescents, M_age = 15.2 years, 55% girls), examined associations between perfectionism (self-oriented and socially prescribed) and identity processes in the domain of future plans. Self-oriented perfectionism predicted increases in commitment making, identification with commitment, and exploration in depth. Socially prescribed perfectionism showed bidirectional positive relations with ruminative exploration. Exploration in depth predicted increases in socially prescribed perfectionism. Findings suggest that perfectionism is an important personality disposition in adolescent identity formation unfolding over time.

最好的我：青春期完美主义和身份认同过程的纵向关联

人格和身份的形成在青少年发展中有着错综复杂的联系。完美主义的人格倾向与身份过程有关，但尚未研究它们在青春期的纵向相互作用。这项四波研究，每波之间有 5 到 6 个月的时间间隔（N  = 744 名白人青少年，M_年龄 = 15.2 岁，55% 女孩），研究了完美主义（自我导向和社会规定）与未来计划领域的身份过程之间的关联。以自我为导向的完美主义预示着做出承诺、认同承诺和深入探索的增加。社会规定的完美主义与沉思探索呈双向正向关系。深入探索预测社会规定的完美主义会增加。研究结果表明，完美主义是青少年身份形成过程中一种重要的人格倾向，随着时间的推移而展开。
