Brief summary

This study will provide a course of schema therapy to adults with eating disorders featuring binge-eating. The treatment will be tailored to certain aspects of personality: early maladaptive schemas, perceived parenting style and temperament. The aim of the study is to determine whether this treatment reduces eating disorder symptoms and behaviours and whether there is a relationship between change in early maladaptive schemas and eating disorder symptoms. People aged 18 or older with eating disorders featuring binge eating (e.g., bulimia nervosa, binge eating disorder) will be eligible to participate in the study. The study will be conducted at multiple sites, including two eating disorder services in the UK and three private practice centres in Australia. The treatment includes 25 x 1-hour sessions over approximately 30 weeks. Participants will complete questionnaire measures before starting treatment, halfway through treatment, at the end of treatment and at 3- and 6-months after treatment is complete. To understand participants' perspective of the treatment, an optional qualitative interview will be conducted after treatment is complete.

This study will provide 25-session course of schema therapy to adults with eating disorders featuring binge-eating. The treatment will be tailored to each participants' unique combination of symptoms early maladaptive schemas, perceived parenting style and temperament. The 25 treatment sessions will be divided into a number of phases: initial assessment session, psychoeducation and orientation to treatment, implementing eating interventions, reflecting on childhood experiences and temperament, in-depth exploration of coping modes, implementing behavioural experiments before preparing for discharge from therapy and planning to prevent relapse. The 25 treatment sessions will occur over approximate 30 weeks and consist of 23 x 1-hour weekly sessions followed by 2 x 1-hour fortnightly sessions. The intervention will be administered through one-on-one face-to-face sessions conducted by experienced psychologists trained in using schema therapy for eating disorders. These sessions will be held in two NHS eating disorder services in the UK and three private practice centres in Australia.
