Extant research suggests that individuals with anorexia nervosa (AN) have deficits in emotion regulation across a variety of domains. The current study investigated associations between specific difficulties with emotion regulation and the core symptoms of AN.
Participants were 192 patients with AN presenting to an intensive eating disorder treatment facility. Emotion regulation was assessed using the multidimensional Difficulties in Emotion Regulation Scale, and associations with body mass index (BMI) at admission, eating disorder cognitions, objective binge eating, subjective binge eating, and purging were examined.
Eating disorder cognitions were significantly associated with multiple forms of emotion dysregulation; however, only lack of emotional awareness was independently related to these symptoms. In contrast, impulse control difficulties when upset was the only emotion regulation impairment associated with the presence of recurrent objective binge eating and recurrent purging in AN. No significant relationships between emotion regulation and BMI or subjective binge eating were detected.
Results point to differential associations between specific emotion regulation deficits and core symptoms of AN. These findings suggest that parsing the construct of emotion regulation as well as the AN phenotype can help to identify the unique ways in which eating disorder symptoms may function to regulate emotions.
现有研究表明，神经性厌食症（AN）患者在多个领域的情绪调节能力存在缺陷。本研究探讨了情绪调节特定困难与 AN 的核心症状之间的关系。
参与者为 192 名就诊于强化饮食障碍治疗机构的 AN 患者。使用多维情绪调节困难量表评估情绪调节，同时还评估了入院时的体重指数（BMI）、饮食障碍认知、客观暴食、主观暴食和催吐与情绪调节的关系。
饮食障碍认知与多种形式的情绪失调显著相关；然而，只有缺乏情绪意识与这些症状独立相关。相比之下，当情绪不安时冲动控制困难是唯一与 AN 中反复客观暴食和反复催吐相关的情绪调节损伤。情绪调节与 BMI 或主观暴食之间没有显著关系。
结果表明，特定的情绪调节缺陷与 AN 的核心症状之间存在差异关联。这些发现表明，对情绪调节结构和 AN 表型进行细分，可以帮助确定饮食障碍症状调节情绪的独特方式。
