Youth perfectionism levels have increased significantly over the last decades. Given the dominance of picture-perfect content, social media are often designated as contributors of this rise. Accordingly, this study examined how exposure to positive social media content might increase adolescents’ perfectionistic dispositions and vice versa. Moreover, it was explored whether upward social comparison and adolescents’ individualism values as well as country play, respectively, a mediating and moderating role. A three-wave panel study was conducted among 1,697 Belgian, French, and Slovenian adolescents ( M age = 15.14, SD age = 1.78, 57.2% girls). At the between-person level, the results showed that higher levels of exposure to positive content are related to higher levels of perfectionism. Higher upward social comparison levels are related to higher levels of exposure to positive content and of socially prescribed perfectionism. A more complex pattern emerged at the within-person level with different results depending on the selected time intervals, countries, and adolescents’ individualistic values.

完美的 Li（f）e：关于积极社交媒体内容和欧洲青少年完美主义的纵向研究

在过去的几十年里，青少年完美主义水平显着增加。鉴于图片完美内容的主导地位，社交媒体通常被认为是这种增长的贡献者。因此，本研究考察了接触积极的社交媒体内容如何增加青少年的完美主义倾向，反之亦然。此外，还探讨了向上的社会比较和青少年的个人主义价值观以及国家是否分别起中介和调节作用。在 1,697 名比利时、法国和斯洛文尼亚青少年中进行了一项三波面板研究（Mage = 15.14，SDage = 1.78,57.2% 女孩）。在人与人之间的层面上，结果表明，对积极内容的接触水平越高，完美主义水平越高。较高的向上社会比较水平与较高的正面内容和社会规定的完美主义接触水平有关。在个人层面出现了更复杂的模式，根据所选的时间间隔、国家和青少年的个人主义价值观，结果会有所不同。
