Introduction

Compensatory eating disorder (CED) is a newly proposed ‘other specified feeding and eating disorder’ characterized by recurrent non-purging compensatory behaviors (e.g., compulsive exercise and/or food restriction), overvaluation of weight/shape, the absence of objective binge-eating episodes, and the absence of low weight or recent significant weight loss. This study compared individuals with CED to individuals with anorexia nervosa (AN), bulimia nervosa (BN), or binge-eating disorder (BED) on measures of psychiatric impairment, eating-disorder (ED) symptomatology, and comorbid internalizing disorders.

Method

Adults (N = 187) with CED, AN, BN, or BED completed measures of ED-related-psychiatric impairment and ED symptomatology. Structured clinical interviews were administered to assess ED and internalizing-disorder diagnoses.

Results

Linear regression models were fit to compare the CED group to full-threshold ED groups on psychiatric impairment, body dissatisfaction, cognitive restraint, negative attitudes towards obesity, and weight suppression. A chi-square difference test examined group differences on internalizing-disorder prevalence. Results indicated that the CED group had high levels of psychiatric impairment, yet psychiatric impairment was significantly lower in the CED group compared to other groups. The AN group had significantly lower body dissatisfaction than the CED group. Individuals with CED had similar cognitive restraint, negative attitudes towards obesity, internalizing psychopathology, and weight suppression compared to other ED groups.

Conclusion

Individuals with CED had substantial ED psychopathology and internalizing-disorder prevalence, comparable to individuals with full-threshold EDs. Individuals with CED had high levels of psychiatric impairment, but their impairment was lower than individuals with full-threshold EDs. Our results indicate that CED is a clinically significant disorder.

补偿性饮食失调和全阈值 DSM 饮食失调：饮食失调相关精神障碍和症状的比较

介绍

补偿性饮食失调（CED）是一种新提出的“其他特定的喂养和饮食失调”，其特征是反复出现的非清除性补偿行为（例如强迫性运动和/或食物限制）、对体重/体型的高估、缺乏客观的暴饮暴食。饮食发作，并且没有低体重或最近体重明显减轻。这项研究将 CED 患者与神经性厌食症 (AN)、神经性贪食症 (BN) 或暴食症 (BED) 患者的精神障碍、饮食失调 (ED) 症状和共病内化障碍进行了比较。

方法

患有 CED、AN、BN 或 BED 的成人（N  = 187）完成了 ED 相关精神障碍和 ED 症状的测量。进行结构化临床访谈以评估 ED 和内化障碍诊断。

结果

线性回归模型适合比较 CED 组与全阈值 ED 组在精神障碍、身体不满意、认知克制、对肥胖的消极态度和体重抑制方面的情况。卡方差异检验检查了内化障碍患病率的群体差异。结果表明，CED 组的精神障碍水平较高，但与其他组相比，CED 组的精神障碍明显较低。AN组的身体不满意程度显着低于CED组。与其他 ED 群体相比，CED 患者具有相似的认知克制、对肥胖的消极态度、内化精神病理学和体重抑制。

结论

与患有全阈值 ED 的个体相比，患有 CED 的个体具有显着的 ED 精神病理学和内化障碍患病率。患有 CED 的个体精神障碍程度较高，但其损伤程度低于患有全阈值 ED 的个体。我们的结果表明 CED 是一种具有临床意义的疾病。
