There has been recent interest in the possibility of dividing bulimia nervosa into two subtypes based on the method of weight prevention utilized by the individual. In an attempt to see if such a division is justified, this study compared 54 purging bulimics with 69 nonpurging bulimics ascertained from a population-based register of Virginia female twins. A bulimic was defined as a "purger" if she engaged in vomiting or laxative abuse. These two groups were examined on a variety of demographic, weight, and personality measures after controlling for the presence of obesity. No significant differences were found between the two groups on any of the variables examined.
最近，人们对根据个体所采用的体重控制方法将神经性贪食症分为两种亚型的可能性产生了兴趣。为了探究这种分类是否合理，本研究对从弗吉尼亚女性双胞胎的人群登记册中确定的54名清除型贪食症患者和69名非清除型贪食症患者进行了比较。如果一名贪食症患者有呕吐或滥用泻药行为，则被定义为“清除型”。在控制了肥胖因素后，对这两组患者进行了各种人口统计学、体重和性格方面的测量。在所检查的任何变量上，两组之间均未发现显著差异。
