神经性贪食症和暴食症（BED）的临床分析研究产生了2种亚型（纯饮食和混合饮食负面影响）。作者旨在（a）用BED复制亚型，（B）考虑亚型的替代方法，（c）测试亚型个体差异的稳定性。对101例患者的聚类分析显示，饮食负性情感亚型（33%）和纯饮食亚型（67%）。饮食负性情感亚型的特点是更大的饮食相关的精神病理学和心理障碍。聚类分析产生了不同的结果，从替代亚型的方法（重性抑郁症或暴饮暴食的频率）。在间隔4周的2个时间点，对73例患者的亚组进行的临床分析亚型分析的数据显示出显著的一致性（kappa = .55）。研究结果表明，适度节食是床的特点，情感障碍发生在一个子集的情况下，代表一个更不安的变种。亚型可能代表合理稳定的个体差异。
Cluster-analytic studies of bulimia nervosa and binge eating disorder (BED) have yielded 2 subtypes (pure dietary and mixed dietary-negative affect). The authors aimed to (a) replicate the subtyping with BED, (b) consider alternative approaches to subtyping, and (c) test the stability in individual differences in the subtyping. Cluster analyses of 101 patients revealed tt dietary-negative affect subtype (33%) and a pure dietary subtype (67%). The dietary-negative affect subtype was characterized by greater eating-related psychopathology and psychological disturbance. Cluster analysis produced different results from alternative subtyping approaches (by major depression or by binge eating frequency). Cluster-analytic subtyping of data at 2 time points 4 weeks apart for a subset of 73 patients demonstrated significant consistency (kappa = .55). Findings suggest that moderate dieting is characteristic of BED and that affective disturbances occur in a subset of cases that represent a more disturbed variant. The subtypes may represent reasonably stable individual differences.
