RESUMEN
Perfectionism is linked to a range of psychopathology, including binge eating. Our study enhanced understanding of the role maternal perfectionistic concerns play in the maintenance of binge eating in emerging adult daughters. A sample of 73 mother-daughter dyads (mean age = 49.51 years for mothers and 19.89 years for daughters) reported on perfectionistic concerns (composite of doubt about actions and concern over mistakes), binge eating, and binge drinking (composite of frequency, severity, and perceptions). Using actor-partner interdependence modelling, mothers' and daughters' perfectionistic concerns were positively associated with their own binge eating (actor effects). Mothers' perfectionistic concerns were positively associated with daughters' binge eating (partner effect), but not vice versa. Perfectionistic concerns did not show significant actor or partner associations with binge drinking, supporting the specificity of our model. Findings suggest binge eating has characterological and interpersonal antecedents.
