Binge eating episodes occur in a significant proportion of the non-clinical population, although only a small proportion of these individuals progress to developing disabling eating disorders. The purpose of this research was to examine the nature of binge eating episodes verses non-binge eating episodes and the nature of subjective binge eating episodes and objective binge eating episodes as they occur in a non-clinical population. This study consisted of 113 undergraduate psychology students who completed a range of self-report measures including the Eating Disorder Inventory-2 (EDI-2), demographics questionnaire and binge diary. Sixty-seven percent reported that they had experienced a binge-eating episode in the previous 12 months, whilst only 40% had experienced a binge-eating episode as measured by DSM-IV criteria. The results indicate that the Bulimia, Body Dissatisfaction and Interoceptive Awareness subscales of the EDI-2 differentiate between binge eating episodes and non-binge eating episodes. Furthermore these results replicate findings that there is no difference between a subjective and objective binge-eating episode. These findings have important implications for the cognitive-behavioural treatment of binge eating.
