Perfectionism is associated with several mental disorders, including depression, anxiety, and eating disorders. The goal of this study was to test the specificity of the associations between perfectionism facets and eating disorder behaviors, by examining whether neuroticism and conscientiousness mediated or moderated associations between these variables. Participants from a representative community sample (N = 407; 47% female) completed questionnaires assessing perfectionism, neuroticism, conscientiousness, and eating disorder behaviors. Neuroticism partially mediated associations between binge eating, restraint, body dissatisfaction, and maladaptive perfectionism facets. Neuroticism did not mediate associations between restriction and achievement striving perfectionism facets. Conscientiousness did not mediate any associations between perfectionism facets and eating disorder behaviors, yet Doubts about Actions interacted with conscientiousness to predict body dissatisfaction. Results indicate that neuroticism is key for understanding general risk factors that lead to myriad internalizing disorders, whereas maladaptive perfectionism has limited usefulness as a specific risk factor for eating disorder behaviors. Nevertheless, there is a unique association between dietary restraint and achievement striving dimensions of perfectionism that cannot be explained by higher-order personality traits.
完美主义与多种精神障碍有关，包括抑郁、焦虑和饮食失调。本研究的目的是通过检验神经质和尽责性是否在这些变量之间的关联中起中介或调节作用，来测试完美主义各维度与饮食失调行为之间关联的特异性。来自代表性社区样本的参与者（N=407；47%为女性）完成了评估完美主义、神经质、尽责性和饮食失调行为的问卷。神经质部分中介了暴食、节食、身体不满和适应不良的完美主义维度之间的关联。神经质不能中介限制和成就追求完美主义维度之间的关联。尽责性不能中介完美主义各维度与饮食失调行为之间的任何关联，但行动疑虑与尽责性相互作用来预测身体不满。结果表明，神经质是理解导致多种内在障碍的一般风险因素的关键，而适应不良的完美主义作为饮食失调行为的特定风险因素的作用有限。然而，饮食限制和成就追求维度的完美主义之间存在独特的关联，不能用高阶人格特质来解释。
