Abstract
PURPOSE: The co-morbidity of binge eating and heavy drinking (BE + HD) is a serious concern due to the high prevalence rates and associated elevated severity. Clarifying the momentary factors that increase risk for binge eating and heavy drinking among BE + HD is important for expanding theoretical models of BE + HD and informing treatment recommendations. The current study used ecological momentary assessment (EMA) to compare the momentary processes maintaining binge eating between BE + HD and individuals with binge eating only (BE-only) and to identify the momentary risk factors for binge eating episodes and heavy drinking episodes among BE + HD. METHODS: Participants (BE + HD: N = 14; BE-only: N = 37) were adults with clinically significant binge eating who completed between 7 and 14 days of EMA prior to treatment. RESULTS: The presence of food and within-day dietary restraint predicted higher odds of binge eating for both groups. Among BE + HD, the presence of alcohol and dietary restraint increased risk for subsequent binge eating and subsequent heavy drinking, and the absence of food increased risk for subsequent heavy drinking. CONCLUSION: These results offer preliminary support for treatment interventions for BE + HD that focus on reducing dietary restraint and teaching strategies for urge management in situations with palatable food or alcohol. Future research should study the maintenance mechanisms of BE + HD with larger, more diverse samples and using study design approaches with more experimenter control (i.e., laboratory experiments). LEVEL OF EVIDENCE: Level IV, multiple time series without intervention.
