The clinical significance of two major aspects of perfectionism, perfectionistic strivings (PS) and perfectionistic concerns (PC), in eating disorders (EDs) symptoms was well‐established among adults. However, no systematic review has assessed evidence examining associations between both unidimensional and multidimensional perfectionism and EDs in early and middle adolescence. For this aim, three online databases (PsycINFO, Medline and PsycArticle) were searched for articles published until January 2019, and observational studies were considered. Study quality was systematically appraised, and results were summarized using a narrative synthesis approach. Fifty‐one cross‐sectional and 28 longitudinal studies were included. Most studies supported the relationship between perfectionism and EDs, with the majority adopting a unidimensional approach for assessing perfectionism. Among studies that employed multidimensional measures of perfectionism, the majority (n = 11) of evidence supported the relationship between eating symptoms and PC, while fewer (n = 5) studies provided significant unique associations with PS. These findings are consistent with the body of research suggesting the strength of the relationship between PC and EDs was greater than between PS and EDs. It was recommended that preventive interventions should be primarily focused on reducing self‐critical perfectionism, since it resulted to be the most relevant perfectionistic dimension in the development of eating symptoms in adolescents.

青少年完美主义与饮食相关症状的关系：系统评价

完美主义的两个主要方面，完美主义努力 (PS) 和完美主义关注 (PC)，在饮食失调 (ED) 症状中的临床意义在成人中已得到公认。然而，没有系统评价评估检查单维和多维完美主义与青春期早期和中期 ED 之间关联的证据。为此，在三个在线数据库（PsycINFO、Medline 和 PsycArticle）中搜索了 2019 年 1 月之前发表的文章，并考虑了观察性研究。系统评估研究质量，并使用叙述综合方法总结结果。包括 51 项横断面研究和 28 项纵向研究。大多数研究支持完美主义和 ED 之间的关系，大多数人采用一维方法来评估完美主义。在采用多维完美主义衡量标准的研究中，大多数（n = 11) 的证据支持饮食症状与 PC 之间的关系，而较少 ( n = 5) 研究提供了与 PS 显着的独特关联。这些发现与研究主体一致，表明 PC 和 ED 之间的关系强度大于 PS 和 ED 之间的关系。建议预防干预应主要侧重于减少自我批评的完美主义，因为它是青少年饮食症状发展中最相关的完美主义维度。
