The perfectionism model of binge eating (PMOBE) is an integrative model explaining why perfectionism is related to binge eating. This study reformulates and tests the PMOBE, with a focus on addressing limitations observed in the perfectionism and binge-eating literature. In the reformulated PMOBE, concern over mistakes is seen as a destructive aspect of perfectionism contributing to a cycle of binge eating via 4 binge-eating maintenance variables: interpersonal discrepancies, low interpersonal esteem, depressive affect, and dietary restraint. This test of the reformulated PMOBE involved 200 undergraduate women studied using a 3-wave longitudinal design. As hypothesized, concern over mistakes appears to represent a vulnerability factor for binge eating. Bootstrapped tests of mediation suggested concern over mistakes contributes to binge eating through binge-eating maintenance variables, and results supported the incremental validity of the reformulated PMOBE beyond perfectionistic strivings and neuroticism. The reformulated PMOBE also predicted binge eating, but not binge drinking, supporting the specificity of this model. The reformulated PMOBE offers a framework for understanding how key contributors to binge eating work together to generate and to maintain binge eating.
暴食症的完美主义模型（PMOBE）是一个综合模型，用于解释为什么完美主义与暴食症有关。本研究重新制定并测试了 PMOBE，重点解决了完美主义和暴食症文献中观察到的局限性。在重新制定的 PMOBE 中，对错误的关注被视为完美主义的一个破坏性方面，通过 4 个暴食症维持变量：人际差异、低人际尊重、抑郁情绪和饮食抑制，导致暴食循环。对重新制定的 PMOBE 的检验涉及使用 3 波纵向设计研究的 200 名本科女性。正如假设的那样，对错误的关注似乎代表了暴食的脆弱因素。有引导的中介测试表明，对错误的关注通过暴食症维持变量导致暴食，并且结果支持了重新制定的 PMOBE 在完美主义追求和神经质之外具有增量有效性。重新制定的 PMOBE 也预测了暴食，但不预测狂饮，支持了该模型的特异性。重新制定的 PMOBE 为理解暴食的关键因素如何共同作用产生和维持暴食提供了一个框架。
