目的：本研究旨在比较神经性贪食症（BN）、暴饮暴食症（BED）和净化障碍（PD）在临床显著变量上的差异，并检查每周一次与每周两次的诊断阈值对进食行为紊乱的实用性。方法：234名BN、BED、或PD通过在线调查的自我报告措施确定，并根据每周一次或两次进行分类-结果：BN比BED和PD更严重。三组在自我报告的抑制和去抑制方面存在显着差异，BN和BED组报告的抑郁水平高于PD组。对于BN，那些每周两次与每周一次的行为更symptomatic.Discussion：BN，BED和PD组在临床上有意义的方式不同。未来的研究需要阐明情绪障碍与饮食行为之间的关系。降低BN的每周两次行为阈值将捕获具有临床显著饮食失调的个体，尽管每周两次阈值可以提供关于BN和BED的失调严重程度的重要信息。(C)出版社：Wiley Periodicals，Inc.
Objective: This study aimed to compare bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD) on clinically significant variables and examine the utility of once versus twice-weekly diagnostic thresholds for disturbed eating behaviors.Method: 234 women with BN, BED, or PD were identified through self-report measures via an online survey and categorized based on either once-weekly or twice-weekly disturbed eating behaviors.Results: BN emerged as a more severe disorder than BED and PD. The three groups differed significantly in self-reported restraint and disinhibition and the BN and BED groups reported higher levels of depression than PD. For BN, those engaging in behaviors twice-weekly versus once-weekly were more symptomatic.Discussion: The BN, BED, and PD groups differed in clinically meaningful ways. Future research need to clarify the relationship between mood disturbances and eating behaviors. Reducing the twice-weekly behavior threshold for BN would capture individuals with clinically significant eating disorders, though the twice-weekly threshold may provide important information about disorder severity for both BN and BED.
