Abstract
PURPOSE: The current study aimed to examine the relationships between impulsivity, dietary restraint, and binge eating frequency in individuals with binge-spectrum eating disorders. METHODS: Secondary data analysis was conducted on baseline data from three ongoing or recently completed clinical trials. 148 participants diagnosed with a DSM-5 eating disorder characterized by binge eating were administered a clinical interview to assess dietary restraint and binge eating frequency and completed a self-report measure of trait impulsivity. RESULTS: Mediation analyses found that increased dietary restraint mediated the relationship between higher impulsivity, particularly greater positive urgency and sensation-seeking, and more frequent binge eating episodes. CONCLUSION: While more research using momentary assessment methods is necessary to confirm our findings, results from the current study call attention to the potential role of dietary restraint in the impulsivity-binge eating relationship for individuals with binge-spectrum eating disorders. LEVEL OF EVIDENCE: Level V descriptive study.
