Effects of Episodic Future Thinkingon Impulsivity and Binge Eating Behaviorof College Students Prone to Binge Eating Disorder
Abstract
The purpose of this study was to examine the effect of episodic future thinking on impulsivity, and binge eating behavior of college students prone to binge eating disorder. The screening was conducted based on 18 points or more of the Binge Eating Behavior Scale (BES) and less than 15 points of the purging behavior scale of the K-BULIT-R and the Korean version of the PHQ-9 (Patient Health Questionnaire-9) among 579 adults including male and female participants. The 31 participants were randomly assigned to each to two groups, the episodic future thinking group (treatment group) and the control group. In this study, both groups provided positive images. The treatment group conducted a mentalization process of a positive event that may occur in the future, and the control group conducted a mentalization process of the Pinocchio story in a positive manner. Subsequently, the delay discounting task and the writing task inducing snack intake were conducted, and the manipulation check of the level of required imagination performance was measured at each stage. Results of the analysis showed a significantly higher AUC value for the treatment group compared to the control group, but no significant difference was found between the groups in the snack intake (g). This study confirmed that episodic future thinking (EFT) is effective on impulsive decision-making of college students prone to binge eating disorder, and does not have sufficient effect on binge eating behavior. Finally, the implications and limitations are discussed, and further research is suggested.
