In the current study, we examine components of the "addictive appetite" model of recurrent binge eating. Specifically, we tested the influence of addictive processes and the influence of emotional regulation processes on recurrent binge eating behaviour. We recruited 79 women in total for the current study: 22 with bulimia nervosa, 26 weight-matched lean comparison women, 15 women with binge eating disorder, and 16 weight-matched overweight/obese comparison women. Participants completed questionnaire assessments of food craving and motivations for eating. Compared with weight-matched comparison women, women with binge-type eating disorders endorse significantly greater levels of food craving, eating for purposes of coping, and eating for purposes of reward enhancement. A cluster analysis revealed that these three traits distinguish women with binge-type eating disorders from weight-matched comparison women. These findings provide support for the addictive appetite model of binge eating behaviour and highlight addictive and emotional regulation processes as potential targets for treatment.
在当前的研究中，我们研究了反复发作性暴食的“成瘾性食欲”模型的组成部分。具体来说，我们测试了成瘾过程和情绪调节过程对反复发作性暴食行为的影响。我们总共招募了 79 名女性参与当前的研究：22 名神经性贪食症患者，26 名体重匹配的瘦对照女性，15 名暴食障碍患者，以及 16 名体重匹配的超重/肥胖对照女性。参与者完成了食物渴望和进食动机的问卷评估。与体重匹配的对照组女性相比，患有暴食型饮食障碍的女性表现出更高水平的食物渴望、为应对目的而进食以及为增强奖励而进食的动机。聚类分析显示，这三个特征将暴食型饮食障碍女性与体重匹配的对照组女性区分开来。这些发现为暴食行为的成瘾性食欲模型提供了支持，并强调了成瘾和情绪调节过程可能成为治疗的目标。
