Description of intervention(s) / exposure
Two ten session face-to-face cognitive behaviour therapies for non-underweight eating disorders delivered over 10 consecutive weeks were compared. The first was Ten-session cognitive behaviour therapy (CBT-T), using the protocol outlined in Waller G, Turner H, Tatham M, Mountford VA, Wade TD. (2019). Brief Cognitive Behavioural Therapy for Non-Underweight Patients: CBT-T for Eating Disorders. Abingdon: Routledge, Taylor & Francis Group. The second was CBT using guided self-help (GSH) based primarily on the self-help books Cooper, P. (2009). Overcoming Bulimia Nervosa and Binge Eating (3rd ed). London, UK: Little, Brown Book Group and Cooper, M., Todd, G., & Wells, A. (2001). Bulimia Nervosa: A Cognitive Therapy Programme for Clients. London, UK: Jessica Kingsley Publisher Ltd. Both were delivered by postgraduate trainee therapists. Both therapies are conducted weekly over 10 weeks (50 minute sessions) and both address eating diaries to promote regular eating and to connect in-session weighing to changes in eating. The CBT-T addresses changes to eating more quickly than GSH and also includes content on body image. The GSH includes several initial sessions on motivation. The number of sessions attended was recorded.
