实验室研究表明，有和没有暴饮暴食症（BED）的参与者的饮食行为，特别是暴饮暴食行为之间存在相当大的差异。然而，这些发现并没有复制在两个现场实验采用生态瞬时评估（EMA），其中肥胖的床和肥胖的非床参与者报告了可比的暴饮暴食行为。在目前的研究中，我们研究了暴饮暴食的差异与创新的评估方案，采用EMA和标准化的基于计算机的饮食回忆程序，以避免过去的实验室和现场研究的一些局限性。肥胖的BED，肥胖的非BED和非肥胖的对照组参与者报告了饮食模式，失控，暴饮暴食和暴食行为的显着差异。特别重要的是，BED参与者比非BED参与者有更多的暴饮暴食和暴食事件。这些研究结果表明，使用EMA结合饮食回忆可能是一个相对客观和有用的方法来评估暴饮暴食行为。研究结果进一步表明，患有卧床不起的人与没有这种疾病的人有明显不同，这可能对DSM-V中的饮食失调诊断产生影响。（C）2009 Elsevier Ltd.保留所有权利。
Laboratory studies have shown considerable differences between the eating behavior, particularly binge eating behavior, of participants with and without binge eating disorder (BED). However, these findings were not replicated in two field experiments employing ecological momentary assessment (EMA) in which obese BED and obese non-BED participants reported comparable binge eating behavior. In the current study, we examined differences in binge eating with an innovative assessment scheme employing both EMA and a standardized computer-based dietary recall program to avoid some of the limitations of past laboratory and field research. Obese BED, obese non-BED, and non-obese control participants reported significant differences in eating patterns, loss of control, overeating, and binge eating behavior. Of particular importance was the finding that BED participants engaged in more overeating and more binge eating episodes than non-BED participants. These findings suggest that the use of EMA in combination with dietary recall may be a relatively objective and useful approach to assessing binge eating behavior. The findings further suggest that individuals with BED are observably different from those without the disorder, which may have implications for eating disorder diagnoses in DSM-V.
