title: Predictors of psychological outcome in patients with eating disorders: A routine outcome monitoring study.
abstract: Identifying predictors of psychological outcome for patients with eating disorders may improve the effectiveness of treatment. Patients with different pre-treatment characteristics and symptoms may benefit from different therapies. This study aimed to identify potential predictors of treatment outcome in a large naturalistic cohort of patients with an eating disorder.
  
  
  
  The study sample included patients (N = 1153) with all types of eating disorders who were receiving residential, day, or outpatient treatment. Remission was defined by means of four different indicators based on the Eating Disorder Examination-Questionnaire global score: 1. achieving reliable change; 2. showing a 50% reduction in baseline symptom severity; 3. reaching the clinical significance cut-off point; and 4. a combination of indicators 2 and 3. Potential predictor variables were investigated in univariate and multivariate Cox regression models.
  
  
  
  Different predictors were found for the four outcome criteria. Patients with high levels of interpersonal distrust at baseline were less likely to have achieved reliable change in eating disorder psychopathology. Higher self-esteem and less body dissatisfaction at baseline was independently associated with a symptom reduction of more than 50% and/or reaching the clinical significance cut-off point. Contrary to our expectations, no differences in outcome were found between the eating disorder subtypes.
  
  
  
  Clinically, it is important to reduce the risk of poor outcome and to achieve a rapid response in treatment using an intervention designed for this purpose, such as shared decision making or an intervention directed at self-esteem or body image, which may act as a catalyst for change. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:863-873).
