title: Development of the eating disorder recovery self-efficacy questionnaire.
abstract: OBJECTIVE
  The purpose of the current investigation was to develop and validate the Eating Disorder Recovery Self-Efficacy Questionnaire (EDRSQ), a self-report measure of self-efficacy to recover from an eating disorder.
  
  
  METHODS
  Participants were 116 female patients with anorexia nervosa, bulimia nervosa, or a subthreshold eating disorder treated at an eating disorder clinic. Patients completed the EDRSQ and measures of eating disorder symptoms and depression.
  
  
  RESULTS
  The EDRSQ contains two internally consistent factors, Normative Eating Self-Efficacy and Body Image Self-Efficacy. Moderate to large correlations between EDRSQ subscales and measures of eating disorder pathology support the convergent validity of the EDRSQ. The EDRSQ demonstrates theoretically consistent relations with constructs that are related to but distinct from self-efficacy. Discriminant validity is reflected in small correlations between EDRSQ subscales and measures of general psychological correlates of disordered eating.
  
  
  CONCLUSIONS
  The EDRSQ is a psychometrically sound measure to assess self-efficacy in patients with a range of eating disorder diagnoses.
