Abstract

The focus of mental health research in emerging fields should be driven by the priorities of people with relevant lived experience. Autism and ADHD are childhood-onset neurodevelopmental conditions that are associated with a range of health inequalities, including increased risk for eating disorders. The evidence base for how best to support neurodivergent individuals who experience disordered eating is still in its infancy, but research suggests that existing clinical approaches are not currently fit for purpose. In this Personal View, through community consultation with autistic people and people with ADHD who have experienced disordered eating, we present a comprehensive ranked list of research topics that people with lived experience prioritise. These priorities could be clustered into two areas: improving outcomes and identifying causal mechanisms. Within the theme of improving disordered eating outcomes, priorities are the improvement of treatment, the need for neurodiversity training in clinical services, and the identification and minimisation of unintended adverse effects of psychological intervention. Within the theme of identifying causal mechanisms, priorities are the identification of risk factors and a better understanding of the effect of autistic or ADHD neurocognitive profiles as potential contributors to eating disorder vulnerability. The final top ten research priorities are contextualised in terms of how they compare to the existing literature on the overlap between autism or ADHD and eating disorders, and concrete suggestions are made for how to implement these research priorities as testable hypotheses. Research informed by these priorities will build necessary understanding of the reasons behind the increased risk for eating disorders in neurodivergent people, and how to best support people who are affected by disordered eating to live positive and fulfilling lives.
