Abstract

OBJECTIVE

The purpose of this study was to examine the 2-year longitudinal stability of objective bulimic (binge eating) episodes (OBEs) and subjective bulimic (binge eating) episodes (SBEs) in a multisite eating disorders sample.

METHOD

Participants included 288 females with eating disorder symptoms who were assessed every 6 months using the Eating Disorder Examination.

RESULTS

Markov modeling revealed considerable longitudinal variability between types of binge eating over 6-month time intervals with relatively higher probability estimates for consistency between OBEs and SBEs than specific transitions between types for the overall sample as well as for eating disorder diagnostic groups. Transition patterns examining all five time points indicated notable variability in binge-eating patterns among participants.

DISCUSSION

These findings suggest that although longitudinal patterns of binge types are variable among individuals with eating disorders, consistency in OBEs and SBEs was the most common pattern observed.

摘要

目的

本研究旨在检查多地点进食障碍样本中客观暴食(暴食发作)和主观暴食(暴食发作)的 2 年纵向稳定性。

方法

参与者包括 288 名有进食障碍症状的女性,每 6 个月使用进食障碍检查进行评估。

结果

马尔可夫模型显示,在 6 个月的时间间隔内,暴食的类型之间存在相当大的纵向变异性,暴食发作和暴食发作之间的一致性概率估计相对较高,而总体样本以及进食障碍诊断组之间的特定类型转换则较低。检查所有五个时间点的转换模式表明,参与者的暴食模式存在显著的可变性。

讨论

这些发现表明,尽管进食障碍个体的暴食类型的纵向模式存在差异,但暴食发作和暴食发作之间的一致性是观察到的最常见模式。
