Although Erikson (1968) originally conceptualized identity development as a process of becoming at home in one's body, little work has been done linking identity development and research on the body. This study examines how trajectories of the development of body esteem over time are related to young people's sense of identity and psychological functioning in a longitudinal sample from age 10 to 24 (N = 967). Using group-based trajectory modeling, three cubic subgroups were determined for each of the three types of body esteem: appearance, weight, and attribution. These groups demonstrated significant variations in the ways in which body esteem changes over time. These trajectory groups importantly differed in relationship to gender, identity coherence, identity confusion, and psychological functioning. Results are discussed in terms of the need to use a sociocultural perspective to explore the body's relation to identity development and the importance of disaggregating mean-level findings using person-centered approaches to determine high-risk groups.

尽管埃里克森（1968）最初将身份认同的发展概念化为在身体上安家的过程，但很少有研究将身份认同的发展与对身体的研究联系起来。本研究在一个从 10 岁到 24 岁的纵向样本中（N=967），考察了随着时间的推移，身体自尊的发展轨迹与年轻人的身份认同和心理功能之间的关系。使用基于群组的轨迹建模，为三种类型的身体自尊（外貌、体重和归因）中的每一种确定了三个三次亚组。这些组显示了身体自尊随时间变化的方式存在显著差异。这些轨迹组在性别、身份一致性、身份混淆和心理功能方面存在重要差异。研究结果讨论了需要使用社会文化视角来探索身体与身份发展的关系，以及使用以个人为中心的方法对平均水平的发现进行细分以确定高风险群体的重要性。
