The current study attempted to characterize the natural course of events linking dietary restraint to urges to binge and actual binge episodes.
Using preprogrammed, hand-held computers, 39 women with bulimia-spectrum eating disorders monitored ongoing eating episodes, dietary restraint, and binge cravings over a 7-29-day interval.
Multilevel modeling analyses indicated that restraint was not systematically elevated before binging. However, elevated restraint preceded strong binge cravings.
Results suggest that dietary restraint may contribute to binge cravings, but may not be a direct antecedent to binge episodes. Such findings are consistent with restraint theory, which suggests that dietary restraint potentiates binging, but does not necessarily trigger its occurrence.
当前研究试图描述将饮食节制与暴饮暴食冲动及实际暴饮暴食发作联系起来的自然事件过程。
39名患有贪食症谱系饮食失调的女性使用预编程的手持电脑，在7至29天的时间间隔内监测正在进行的饮食发作、饮食节制和暴饮暴食欲望。
多水平模型分析表明，在暴饮暴食之前，节制并没有系统性地升高。然而，在强烈的暴饮暴食欲望之前，节制有所升高。
结果表明，饮食节制可能会导致暴饮暴食欲望，但不一定是暴饮暴食发作的直接前提。这些发现与节制理论一致，该理论认为饮食节制会增强暴饮暴食，但不一定引发其发生。
