Binge eating is a core symptom of eating disorders that often occurs in response to increases in negative affect. Recent data suggest that negative affect arising from interpersonal stressors is particularly potent at triggering binge eating. Given that binge eating is conceptualized as a maladaptive strategy for regulating emotions in individuals who have pre-existing deficits in this domain, training in emotion regulation may help persons susceptible to binge eating to better manage negative affect from interpersonal stress, thereby reducing their vulnerability to binge eating. The current study examined whether use of emotion regulation strategies (i.e., cognitive reappraisal versus expressive suppression) while being ostracized via Cyberball differentially impacts subsequent emotions and eating behaviors during a taste test. Females with binge eating (N = 53) and without binge (N = 51) were recruited and trained on either cognitive reappraisal or expressive suppression. Participants then engaged in a Cyberball paradigm designed to ostracize them, and they were asked to simultaneously implement the learned emotion regulation strategy. Subsequently, all participants completed a taste test, during which they consumed pretzels and chocolate M&Ms. Neither binge eating status nor emotion regulation strategy had a significant main effect on emotions or eating behaviors after Cyberball. Further, no significant interaction effects between binge eating status and emotion regulation strategy were detected. The hypothesis that use of cognitive reappraisal compared to expressive suppression can lead to reduced negative emotions as well as reduced eating behaviors was not supported. Non-significant results may be due to a lack of understanding or compliance with emotion regulation instructions. Participants reported using similar levels of both cognitive reappraisal and expressive suppression strategies during Cyberball despite being trained and instructed to use one of the two strategies. Further investigation of the negative effects of interpersonal stress in persons with binge eating is warranted. Future studies may benefit from examining the use of other emotion regulation strategies, as well as more intensive emotion regulation training.
