The current study evaluates the clinical significance and distinctiveness of purging disorder (PD), an eating disorder characterized by recurrent purging in the absence of objective binge episodes (OBE) among normal-weight individuals.
Women with PD (n = 37), bulimia nervosa (BN; n = 39), or no eating disorder (n = 35) completed clinical assessments. Women with PD (n = 23) and BN (n = 25) completed 6-month follow-up assessments.
Compared with controls, both eating-disordered groups reported significantly higher eating, Axis I, and Axis II pathology. Compared with BN, PD was associated with significantly lower eating concerns, disinhibition, and hunger. At 6-month follow-up, rates of remission did not differ significantly between PD and BN, and crossover between disorders was rare.
PD appears to be a clinically significant and potentially distinctive eating disorder.
本研究评估清除障碍（PD）的临床意义及独特性，清除障碍是一种饮食失调症，其特征为正常体重个体在无客观暴饮暴食发作（OBE）的情况下反复清除行为。
患有清除障碍（n = 37）、神经性贪食症（BN；n = 39）或无饮食失调症（n = 35）的女性完成了临床评估。患有清除障碍（n = 23）和神经性贪食症（n = 25）的女性完成了6个月的随访评估。
与对照组相比，两个饮食失调组报告的饮食、轴I和轴II病理学问题均显著更高。与神经性贪食症相比，清除障碍与显著更低的饮食担忧、去抑制和饥饿感相关。在6个月的随访中，清除障碍和神经性贪食症之间的缓解率没有显著差异，且疾病交叉情况罕见。
清除障碍似乎是一种具有临床意义且可能独特的饮食失调症。
