最近的饮食失调模型强调了反刍思维在不健康饮食行为发生中的重要性。因此，本研究的目的是检查的影响，诱导反刍和分心的愿望，从事在厌食症（AN）和神经性贪食症（BN）的进食相关症状。在悲伤诱导后，鼓励AN（n = 38），BN（n = 37）和非进食障碍对照组（CG; n = 36）的女性进行沉思或分心的情绪调节方式。在基线和情绪调节诱导后，评估悲伤感、戒食欲望（DTA）和暴饮暴食欲望（DTB）。主要结果表明，反刍导致显着增加的DTA在AN组和BN患者的DTB。在对照组中，牵张后DTA显著降低。虽然有显着增加主观悲伤的反刍条件下，没有发现分心条件的变化。结果表明，悲伤时的反刍对饮食失调症中与进食相关的症状有不利影响。
Recent models of eating disorders emphasize the importance of ruminative thinking in the occurrence of unhealthy eating behavior. Hence, the aim of the current study was to examine the influence of induced rumination and distraction on the desire to engage in eating-related symptoms in anorexia (AN) and bulimia nervosa (BN). After a sadness induction, either a ruminative or distractive emotion regulation style was encouraged in women with AN (n = 38), BN (n = 37), and non-eating disordered controls (CG; n = 36). At baseline and after the emotion regulation induction feelings of sadness, desire to abstain from eating (DTA) and desire to binge (DTB) were assessed. Main results reveal that rumination led to a significant increase of DTA in the AN group and of DTB in patients with BN. In the CG, DTA significantly decreased after distraction. Although there were significant increases in subjective sadness in the rumination condition, no changes were found in the distraction condition. The results suggest that rumination in response to sadness has a detrimental effect on eating-related symptoms in eating disorders.
