title: Application of the Research Domain Criteria (RDoC) framework to eating disorders: emerging concepts and research.
abstract: The Research Domain Criteria (RDoC) project was initiated by the National Institute of Mental Health as a heuristic for addressing the limitations of categorical, symptom-based psychiatric diagnoses. RDoC is conceptualized as a matrix, with the rows representing dimensional constructs or domains implicated in the expression of psychiatric symptoms and the columns representing units of analysis that can be used to assess dimensional constructs (i.e., genes, molecules, cells, circuits, physiology, behavior, and self-reports). Few studies in eating disorders have adopted an RDoC framework, but accumulating data provide support for the relevance of RDoC dimensions to eating disorder symptoms. Herein, we review findings from RDoC-informed studies across the five domains of functioning included in the RDoC matrix-negative valence systems, positive valence systems, cognitive systems, systems for social processes, and arousal and regulatory systems-and describe directions for future research utilizing RDoC to enhance study design and treatment development in eating disorders.
