Questions have been raised about the validity of binge eating disorder (BED) as psycho-pathologically distinct from other forms of overeating. Our purpose was to ascertain whether BED individuals differed in important ways from nonbinging obese adults.
BED adults were recruited from the community as were weight-matched (obese) and normal-weight control (NWC) groups. All groups were equivalent for age and gender distribution, and were assessed on several personality traits and eating behaviors.
BED individuals and obese controls did not differ on the personality traits. Both were more reward sensitive, and had greater anxiousness, impulsivity, and addictive personality traits than NWC. However, BED individuals reported significantly greater hedonic eating compared with the obese, who had higher levels than NWC.
Our findings provided no evidence of a psychological identity unique to obese adults with BED although their eating behaviors are markedly hedonically driven-i.e., more responsive to factors external to physiological needs.
关于暴饮暴食症（BED）在心理病理学上是否与其他形式的暴饮暴食不同存在疑问。我们的目的是确定患有暴饮暴食症的个体与非暴饮暴食的肥胖成年人在重要方面是否存在差异。
从社区招募患有暴饮暴食症的成年人以及体重匹配（肥胖）和正常体重对照（NWC）组。所有组在年龄和性别分布上相当，并对几种人格特质和饮食行为进行评估。
患有暴饮暴食症的个体和肥胖对照组在人格特质上没有差异。两者都对奖励更敏感，并且比正常体重对照组有更高的焦虑、冲动和成瘾人格特质。然而，与肥胖者相比，患有暴饮暴食症的个体报告的享乐性饮食明显更多，而肥胖者的享乐性饮食水平高于正常体重对照组。
我们的研究结果没有提供证据表明患有暴饮暴食症的肥胖成年人具有独特的心理特征，尽管他们的饮食行为明显受享乐驱动，即对生理需求之外的因素反应更强。
