Brief Summary

This study aims to test the utility of a newly developed clinician competence scale for those delivering Cognitive-Behaviour Therapy for Eating Disorders (CBT-ED), specifically assessing the inter-rater reliability of the measure.

Detailed Description

Cognitive-behavioural therapy for eating disorders (CBT-ED) is currently one of the NICE (2017) recommended treatments for anorexia nervosa and the only treatment recommended for bulimia nervosa, binge-eating disorder and other specified feeing and eating disorders. When clinicians adhere to evidence-based CBT-ED treatment manuals, CBT-ED has shown demonstrable levels of effectiveness in a range of eating disorders, comparable to outcomes in controlled research settings. A key component of CBT-ED found so effective in the treatment of eating disorders is a stronger focus on behavioural change tasks which is key for changing biased thinking. However, clinicians often drift from using behavioural change components and instead focus more on the cognitive aspects of therapy, or indeed drift away from treatment manuals substantially. Therefore, a suitable measure that can accurately assess how well a clinician is delivering the therapeutic competences that ensures patients are receiving evidence-based CBT-ED thus providing them with the best chance of reaching maximum recovery is important. Whilst numerous scales have been developed, none have yet been found suitable for eating disorders, as they do not have a strong focus on the key behavioural aspects of CBT-ED. Therefore, a team of clinical researchers developed the Cognitive Behaviour Therapy Scale for Eating Disorders (CBTS-ED). This pilot study will use CBT-ED therapy session audio-recordings, and different expert and non-expert raters to a) assess the inter-rater reliability of the CBTS-ED and b) assess whether the CBTS-ED can accurately detect improvement in competence among clinicians currently undergoing post-graduate diploma training in CBT-ED. The findings from this study will provide information about the reliability of the CBTS-ED scale and its possible future uses in predicting patient outcomes.

GroupInterventionDescription
CBT-ED trainees and therapists.Recording of CBT-ED session.Qualified clinicians delivering CBT-ED throughout a variety of treatment settings, working with adult eating disorder patients. Clinicians will audio-record CBT-ED therapy sessions with their eating disorder patients.
Raters/Judges.Assessment of CBT-ED clinician competence.Either experts or non-experts in the field of CBT-ED. Raters will use the CBTS-ED to assess clinician competence when listening to the therapy session audio-recordings.
Eating Disorder patients.Recording of CBT-ED session.Adult (18+ years) eating disorder patients currently accessing CBT-ED from one of the CBT-ED therapists/trainees stated above. Patients will have one of their therapy sessions audio-recorded.
