Note. Estimated marginal means (EMM), standard error (SE), and ANCOVA results are presented in Table 2. When statistically adjusting for depressive symptoms, individuals with BED and general impulsivity (GI+) had significantly greater impulsivity, different numbers of lifetime psychological diagnoses, and greater weight concern than individuals without general impulsivity (GI−). BMI = Body Mass Index; ICS = Impulsivity Control Scale; BDI = Beck Depression Inventory; RSES = Rosenberg Self Esteem Scale; EDE = Eating Disorder Examination; OBE = objective binge episode. Bold indicates significant results.
