It is well understood that mood intolerance is a predictor of eating disorder (ED) symptoms. However, it is unclear whether intolerance of specific emotional experiences predicts ED symptoms. The current study used an ecological momentary assessment design to assess associations between the intensity and intolerance of general and body-related self-conscious emotions and facets of restrictive eating. Participants were 151 female undergraduate students (M = 18.99, SD = 1.30 years) who completed six surveys per day for 10 consecutive days. Participants reported on the intensity and intolerance of general and body-related shame, guilt, envy, and embarrassment and cognitive restraint (thoughts about restrictive eating) and behavioral restriction (act of restrictive eating) facets of restrictive eating. Data were analyzed using multilevel modeling. Based on the between-person findings, participants higher on intensity and intolerance of general and body-related self-conscious emotions experienced higher levels of cognitive restraint and behavioral restriction relative to individuals with lower levels of the emotion intensity and intolerance predictors on average. Based on the within-person findings, experiencing a higher intolerance of body-related self-conscious emotions compared to one's average was particularly important when examining behavioral restriction. Experiencing a higher intolerance of body-related envy was able to predict increased behavioral restriction at the time of the next report. These findings may inform tailored treatment targets for mood intolerance and restrictive eating.
人们普遍认为，情绪不耐受是饮食失调（ED）症状的预测因素。然而，目前尚不清楚特定情绪体验的不耐受是否可以预测 ED 症状。本研究采用生态瞬时评估设计，评估了一般和与身体相关的自我意识情绪的强度和不耐受与限制进食特征之间的关联。参与者为 151 名女性本科生（M=18.99，SD=1.30 岁），他们在连续 10 天内每天完成 6 次调查。参与者报告了一般和与身体相关的羞耻、内疚、嫉妒和尴尬以及认知限制（关于限制进食的想法）和限制进食行为（限制进食行为）特征的强度和不耐受。使用多层模型进行数据分析。基于个体间的发现，与情绪强度和不耐受预测因子平均水平较低的个体相比，一般和与身体相关的自我意识情绪强度和不耐受较高的参与者经历了更高水平的认知限制和行为限制。基于个体内的发现，与自身平均水平相比，经历更高的身体相关自我意识情绪不耐受对于考察行为限制尤为重要。与身体相关的嫉妒情绪不耐受程度较高，能够预测下一次报告时行为限制的增加。这些发现可能为情绪不耐受和限制进食提供有针对性的治疗目标。
