title: Eating disorder beliefs and behaviours across eating disorder diagnoses.
abstract: OBJECTIVE
  To test for differences between diagnostic groups on the severity of eating disorder beliefs and behaviours, evaluate the clinical significance of such differences, and assess the extent to which these beliefs and behaviours may be present at clinically significant levels across eating disorder diagnoses.
  
  
  METHODS
  136 adult women outpatients (aged 18-65, with a BMI over 15) were diagnosed with an eating disorder and completed the Stirling Eating Disorder Scale.
  
  
  RESULTS
  The expected pattern of statistically significant differences was found between diagnostic groups on anorexic dietary beliefs and behaviours and bulimic dietary beliefs and behaviours. A high percentage of participants in each diagnostic group scored above the clinical cut-off on the eating disorder belief and behaviour measures and a very high percentage of participants in each group reported clinically significant levels of restricting beliefs.
  
  
  CONCLUSIONS
  Transdiagnostic or functional analytic approaches to treatment planning may lead to more effective interventions than current, diagnostically-based, care pathways. The high prevalence of restricting beliefs reported suggested that this may need to be a key focus for intervention for the majority of individuals presenting with an eating disorder.
