The Centre for Research on Eating Disorders at Oxford (CREDO) is funded by the Wellcome Trust and was founded in 1981.

CREDO has been responsible for the development and evaluation of many of the leading treatments for adults with eating disorders:

  • Cognitive behaviour therapy for bulimia nervosa (CBT-BN) and interpersonal psychotherapy for bulimia nervosa (IPT-BN)
  • Transdiagnostic CBT for eating disorders (CBT-E)
  • Cognitive behavioural self-help for eating disorders (guided and unguided).

In addition, CREDO has developed some of the most widely used measures of eating disorder features and their secondary effects:

  • Eating Disorder Examination interview (EDE)
  • Eating Disorder Examination questionnaire (EDE-Q)
  • Clinical Impairment Assessment questionnaire (CIA)

CREDO is currently engaged in three main lines of research:

  1. The evaluation of transdiagnostic approaches to the treatment of eating disorders, specifically CBT-E and transdiagnostic IPT
  2. The development and testing of scalable and cost-effective methods for training therapists to deliver evidence-based psychological treatments 
  3. The development and evaluation of online psychological interventions and, in particular, a direct-to-user form of CBT-E (CBTe).

CREDO has a research website - - which describes its work in more detail.
