Objective: To determine predictors of treatment outcomes in patients with Bulimic Eating Disorders treated with Interpersonal Psychotherapy (IPT). Design: Following initial assessment, 80 patients with diagnoses of Bulimia Nervosa or Eating Disorders Not Otherwise Specified (EDNOS), entered treatment in the form of 16 sessions of IPT. Patients were assessed using a validated semi-structure interview (Clinical Eating Disorders Rating Instrument-CEDRIC) and completed measures of self-esteem (Rosenberg Self-esteem Scale-RSE), eating psychopathology (Eating Disorders Examination Questionnaire-EDE-Q), interpersonal functioning (Inventory of Interpersonal Functioning- IIP-32), and depression (Beck Depression Inventory-BDI). Method: Remission and recovery after 16 sessions of IPT were the two outcomes of interest. Univariate analysis and a series of backwards stepping logistic regressions were performed to determine the variables associated with remission and recovery. Result: Low self-esteem and less interpersonal problems were the main predictors of poor outcome. Conclusion: As patients with Bulimic Disorders with low levels of interpersonal problems and high levels of low self-esteem are likely to do less well with IPT, different type of treatment should be offered to them. A randomized controlled trial could explore this hypothesis in more detail.
