In the current study, we were interested in developing a typology of eating in patients with bulimia nervosa (BN) based on the size of the eating episode, whether the episode was followed by self-induced vomiting, and the degree of loss of control (LOC) self-reported by participants.
Twenty-one women with BN, purging type, were evaluated using the Nutritional Data System for Research, the Eating Disorders Examination, and the Matrix.
The most common type of episode resembled what might be termed "normal" eating, which involved the consumption of <1,000 kcal with no sense of LOC and no vomiting. There was an increase in severity of self-assessed LOC in objectively large eating episodes with vomiting. Self-reported hunger prior to eating episodes did not seem to be predictive of subsequent behavior. Most people were engaged in other behaviors while eating.
The results of this study suggest a typology that included primarily four types of eating episodes. The results also suggest that when LOC is assessed on a Likert-scale rather than as a dichotomous variable, there is considerable variability in self-assessed degree of LOC.
在本研究中，我们有兴趣根据暴食发作的大小、是否随后进行自我诱导呕吐以及参与者自我报告的失控程度，为神经性贪食症患者建立一种饮食类型学。
对 21 名暴食症（伴或不伴呕吐）患者使用营养数据系统研究、饮食障碍检查和矩阵进行评估。
最常见的发作类型类似于“正常”进食，涉及摄入<1000 卡路里，无失控感，无呕吐。在有呕吐的客观大发作中，自我评估的失控程度加重。进食前的饥饿感似乎不能预测随后的行为。大多数人在进食时还从事其他行为。
本研究结果提示存在一种类型学，主要包括四种进食发作类型。结果还表明，当 LOC 在李克特量表上评估而不是作为二分类变量评估时，自我评估的 LOC 程度存在相当大的变异性。
