Abstract

Objective

Despite substantial research indicating difficulties with emotion regulation across eating disorder presentations, emotion regulation has yet to be studied in adults with avoidant/restrictive food intake disorder (ARFID). We hypothesized that (1) those with ARFID would report greater overall emotion regulation difficulties than nonclinical participants, and (2) those with ARFID would not differ from those with other eating disorders on the level of emotion regulation difficulty.

Methods

One hundred and thirty-seven adults (age 18–30) from an outpatient clinic with ARFID (n = 27), with other primarily restrictive eating disorders (e.g., anorexia nervosa; n = 34), and with binge/purge eating disorders (e.g., bulimia nervosa; n = 51), as well as nonclinical participants (n = 25) recruited via Amazon Mechanical Turk (MTurk) completed the Difficulties in Emotion Regulation Scale (DERS). We compared DERS scores across groups.

Results

In line with expectations, patients with ARFID scored significantly higher than nonclinical participants on the DERS Total (p = 0.01) with a large effect size (d = 0.87). Also as hypothesized, those with ARFID did not differ from those with other primarily restrictive (p = 0.99) or binge/purge disorders (p = 0.29) on DERS Total.

Discussion

Adults with ARFID appear to exhibit emotion regulation difficulties which are greater than nonclinical participants, and commensurate with other eating disorders. These findings highlight the possibility of emotion regulation difficulties as a maintenance mechanism for ARFID.

回避型/限制型食物摄入障碍中的情绪调节困难。

目的：尽管有大量研究表明各种进食障碍表现都存在情绪调节方面的困难，但我们尚未对回避型/限制性食物摄入障碍（ARFID）成人的情绪调节进行研究。我们假设：（1）与非临床参与者相比，ARFID 患者的总体情绪调节困难程度更高；（2）在情绪调节困难程度上，ARFID 患者与其他进食障碍患者没有差异：来自门诊诊所的 137 名成人（18-30 岁）完成了情绪调节困难量表（DERS），他们分别患有 ARFID（n = 27）、其他主要限制性进食障碍（如神经性厌食症；n = 34）和暴饮暴食进食障碍（如神经性贪食症；n = 51），以及通过 Amazon Mechanical Turk（MTurk）招募的非临床参与者（n = 25）。我们比较了各组的 DERS 分数：结果：与预期一致，ARFID 患者在 DERS 总分上的得分明显高于非临床参与者（p = 0.01），且效应大小较大（d = 0.87）。此外，正如假设的那样，在 DERS 总分上，ARFID 患者与患有其他主要限制性障碍（p = 0.99）或暴饮暴食障碍（p = 0.29）的患者没有差异：讨论：患有 ARFID 的成年人似乎比非临床参与者表现出更大的情绪调节困难，这与其他进食障碍是一致的。这些发现突出表明，情绪调节障碍可能是 ARFID 的一种维持机制。

期刊介绍： Articles featured in the journal describe state-of-the-art scientific research on theory, methodology, etiology, clinical practice, and policy related to eating disorders, as well as contributions that facilitate scholarly critique and discussion of science and practice in the field. Theoretical and empirical work on obesity or healthy eating falls within the journal’s scope inasmuch as it facilitates the advancement of efforts to describe and understand, prevent, or treat eating disorders. IJED welcomes submissions from all regions of the world and representing all levels of inquiry (including basic science, clinical trials, implementation research, and dissemination studies), and across a full range of scientific methods, disciplines, and approaches.
