Emotion intolerance and perfectionism are two maintaining mechanisms to eating disorder symptomology. However, it is unclear how these mechanisms relate to one another. This study explored whether perfectionism is a vulnerability factor for facets of restrictive eating in the context of body-related emotions.
Female undergraduate students (N = 148) completed questionnaires assessing baseline levels of self-critical perfectionism and personal standards perfectionism. Participants then engaged in an ecological momentary assessment protocol where body-related emotion intolerance and restrictive eating facets (cognitive restraint and behavioral restriction) were assessed over 10 consecutive days. Multilevel modeling and simple slopes analysis were used to explore these moderated relationships. Within-person (Level 1 body-related emotion intolerance) and between-person (Level 2 perfectionism dimensions) relationships were examined.
Based on the analyses, both self-critical and personal standards perfectionism dimensions interacted with body-related emotion intolerance to predict increases in restrictive eating facets.
These findings indicate that personal standards perfectionism, though conceptualized as the less maladaptive dimension of perfectionism, should not be ignored when conceptualizing and intervening with restrictive eating. Recommendations are provided on how to refine treatment targets to be more attuned with situations that elicit body-related emotion intolerance.
情绪不耐受和完美主义是饮食失调症状的两种维持机制。然而，尚不清楚这些机制之间是如何相互关联的。本研究探讨了在与身体相关的情绪背景下，完美主义是否是限制饮食各方面的一个脆弱因素。
148名本科女生完成了评估自我批判完美主义和个人标准完美主义基线水平的问卷。参与者随后参与了一个生态瞬时评估方案，在连续10天内评估与身体相关的情绪不耐受和限制饮食各方面（认知抑制和行为限制）。采用多层次建模和简单斜率分析来探究这些调节关系。研究了个体内部（第1层与身体相关的情绪不耐受）和个体之间（第2层完美主义维度）的关系。
基于分析，自我批判和个人标准完美主义维度均与与身体相关的情绪不耐受相互作用，以预测限制饮食各方面的增加。
这些发现表明，个人标准完美主义虽然被概念化为完美主义中适应性较差的维度，但在对限制饮食进行概念化和干预时不应被忽视。针对如何完善治疗目标以更好地适应引发与身体相关情绪不耐受的情况提供了建议。
