It is important to determine the optimal manner of categorising eating disorder patients so as to aid in the understanding of their specific psychopathological state.
We compared subgroups of eating disorder patients divided according to different sets of factors, using a structured interview which elicits the specific psychopathological features of these illnesses. The patients, comprising 116 consecutive women admitted to two university-affiliated eating disorder clinics, were grouped according to DSM-III-R criteria, clinical presentation (purging, binge eating), nutritional status, and age.
The clearest separation of groups was afforded by the clinical dimension of purging as opposed to not purging. This was superior to DSM-III-R criteria. Other systems, such as presence of binge eating, and various levels of nutritional status and of age, were clearly inferior.
The presence or absence of purging behaviour appears to offer the most heuristic means of categorising eating disorder patients with respect to their specific psychopathological state.
确定对饮食失调患者进行分类的最佳方式，对于帮助理解他们特定的精神病理状态很重要。
我们使用一种能引出这些疾病特定精神病理特征的结构化访谈，比较了根据不同因素集划分的饮食失调患者亚组。这些患者为连续入住两家大学附属医院饮食失调诊所的116名女性，她们根据《精神疾病诊断与统计手册》第三版修订版（DSM-III-R）标准、临床表现（清除行为、暴饮暴食）、营养状况和年龄进行分组。
与未出现清除行为相比，清除行为这一临床维度能最清晰地将各亚组区分开来。这优于DSM-III-R标准。其他分类系统，如是否存在暴饮暴食以及不同水平的营养状况和年龄，明显较差。
就饮食失调患者的特定精神病理状态而言，清除行为的有无似乎为分类提供了最具启发性的方法。
