title: The Munich eating and feeding disorder questionnaire (Munich ED-Quest) DSM-5/ICD-10: validity, reliability, sensitivity to change and norms.
abstract: OBJECTIVE
  The aim of the article is to report on the psychometric properties of a newly developed self-rating scale (Munich Eating and Feeding Disorder Questionnaire) for the detailed assessment of eating and feeding disorders on the basis of the DSM-5 criteria. The questionnaire aims at developing a comprehensive assessment of eating disorder symptoms suitable for severity ratings with regard to total scale and subscales, for deriving eating disorder diagnoses according to DSM-5 and ICD-10 and for measuring (intervention induced) changes over time.
  
  
  METHODS
  Items were formulated by clinical experts and entered into factor analysis in two separate samples of eating-disordered inpatients. Additionally, 47 clinical and 547 community control participants were assessed. Internal consistency and sensitivity to change over time are also reported.
  
  
  RESULTS
  Three subscales were identified covering 'preoccupation with figure and weight', 'bingeing and vomiting' and 'inappropriate compensatory behaviour' for current and past state. Test-retest reliability for the three subscales ranged between .95 and .98 (current status). A high sensitivity to change during inpatient treatment from admission to discharge was expressed in high effect sizes; for the total score (current status) for all eating disorders, the effect size was 1.70. Effect sizes for anorexia nervosa were mostly lower than those for bulimia nervosa. Clinical and community controls obtained significantly lower scores compared with eating-disordered patients.
  
  
  CONCLUSIONS
  This new DSM-5 questionnaire shows satisfying psychometric properties and is well suited for the rating of eating disorder severity in clinical practice and research.
