Objective: Eating disorder symptomatology generally develops during adolescence and emerging adulthood. Previous research has focused on the role of identity formation or body image in the development of eating disorder symptomatology, but integrative work is lacking. For this reason, the present cross-sectional study examined the mediating role of body dissatisfaction in the relation between identity formation and eating disorder symptomatology. Method: The sample comprised 659 participants between 15 and 30 years old (68.9% females; Mage = 19.44; SDage = 3.99). All participants completed self-report measures on identity (Self-concept and Identity Measure), body dissatisfaction (the Body Image Feelings and Attitudes subscale of the Body Investment Scale and the Body Dissatisfaction subscale of the Eating Disorder Inventory-3), and eating disorder symptomatology (Eating Disorder Inventory-3). Latent variable modeling from a structural equation modeling approach was used. Results: First, identity formation significantly predicted eating disorder symptomatology. Additionally, indirect effects were found linking identity formation to eating disorder symptomatology through the mechanism of body dissatisfaction. No significant differences between males and females or between adolescents and emerging adults on direct or indirect effects were found. Conclusion: The present study indicated that body dissatisfaction mediated the relationship between identity formation and eating disorder symptomatology during mid-to-late adolescence and emerging adulthood. Provided that the present findings can be replicated in a future longitudinal study, they demonstrate that both identity formation and body dissatisfaction should be taken into account in prevention and intervention programs targeting eating disorder symptomatology.

身体不满意作为青少年和新兴成年人身份形成与饮食失调症状学之间的中介

目的：进食障碍症状学通常发生在青春期和成年期。以前的研究集中在身份形成或身体形象在饮食失调症状发展中的作用，但缺乏综合工作。出于这个原因，目前的横断面研究检查了身体不满意在身份形成与饮食失调症状学之间的关系中的中介作用。方法：样本包括 659 名 15 至 30 岁的参与者（68.9% 为女性；Mage = 19.44；SDage = 3.99）。所有参与者完成了关于身份的自我报告测量（自我概念和身份测量），身体不满意（身体投资量表的身体形象感觉和态度子量表和饮食失调量表的身体不满意子量表-3），和饮食失调症状学（饮食失调清单-3）。使用了来自结构方程建模方法的潜变量建模。结果：首先，身份形成显着预测饮食失调症状。此外，发现通过身体不满意的机制将身份形成与饮食失调症状联系起来的间接影响。在直接或间接影响方面，男性和女性之间或青少年和新兴成年人之间没有显着差异。结论：本研究表明，在青春期中后期和成年期，身体不满意在身份形成与进食障碍症状之间起中介作用。如果目前的研究结果可以在未来的纵向研究中复制，
