Autism and ADHD in adult patients with Bulimia Nervosa, Binge Eating Disorder, and/or Obesity: a scoping review protocol

Research output: Other contribution


Background: Autism and ADHD are overrepresented in adult patients with Bulimia Nervosa, Binge Eating Disorder, and Obesity, and have significant clinical implications for the treatment of these disorders. Despite this, there are substantial evidence gaps in the literature regarding prevalence rates; experiences and perspectives; clinical differences and outcomes; and suitable, effective treatments. Identifying these gaps will help inform future research priorities to improve clinical experience and practice.

Objectives: This scoping review aims to map the existing literature on the prevalence of autism and ADHD traits in adult patients with Bulimia Nervosa, Binge Eating Disorder, or Obesity; the lived experiences and perspectives of this group; differences in presentation, comorbidities, and treatment outcomes; and potential treatment adaptations or adjunct therapies.

Methods and Analysis: This scoping review will follow the method outlined in the JBI Manual for Evidence Synthesis (2020) and reporting will follow the PRISMA Extension for Scoping Reviews (2018). The following electronic databases will be searched: Embase, MEDLINE via Ovid, PsychINFO, Web of Science, CENTRAL, and Scopus. Reviews will not be included but reference lists and citations of any reviews or included papers will also be searched. Full text must be available in English, and date range will not be restricted. Two independent reviewers will conduct the title and abstract screening, full-text screening, data charting, and data extraction. Included studies will be represented on an evidence map and data will be extracted and presented in a tabular form summarising relevant findings. A third reviewer will be consulted if discrepancies occur. Critical appraisal of studies was outside the scope of this review.

Ethics and dissemination: Ethics approval is not required for this scoping review. Findings from this research will be shared through conferences, scientific journals, and various media/social media platforms. We will also engage with educational institutions, and our research network, including the PEACE pathway, dedicated to developing autism-friendly approaches to ED treatment. Lastly, we will consult people with lived experience on the findings to incorporate stakeholder’s’ own opinions into future research priorities in this area. This project is funded by the NIHR Maudsley Biomedical Research Centre (BRC).
