The present work investigates differences in psychiatric symptoms and self-injurious behaviors among different forms of purging behavior in eating disorders (ED).
The sample was composed of 398 subjects consecutively referred to an outpatient ED unit.
Both in anorexia nervosa (AN) and bulimia nervosa (BN), psychiatric symptoms were significantly more serious in purging compared to nonpurging groups, while no significant difference emerged among divergent forms of purging behaviors. The presence of multiple methods to control weight appeared to be a predictor of impulsive behaviors, as subjects who used both vomiting and laxatives reported significantly higher frequency of self-injurious behaviors. In BN, the self-injury was often a suicide attempt.
The impact of purging behavior on the prognosis of AN and BN should be further studied since our research has shown a trend towards more frequent self-damaging behaviors in subjects who resort to multiple forms of purging behavior.
本研究调查饮食失调（ED）中不同形式的清除行为在精神症状和自我伤害行为方面的差异。
样本由398名连续转诊至门诊ED科室的受试者组成。
在神经性厌食症（AN）和神经性贪食症（BN）中，与非清除组相比，清除行为组的精神症状明显更严重，而不同形式的清除行为之间未出现显著差异。多种控制体重方法的存在似乎是冲动行为的一个预测因素，因为同时使用呕吐和泻药的受试者报告的自我伤害行为频率显著更高。在BN中，自我伤害行为通常是自杀未遂。
清除行为对AN和BN预后的影响应进一步研究，因为我们的研究表明，采用多种形式清除行为的受试者中自我伤害行为更频繁的趋势。
