Empirically sufficient symptom sets as a path to validity and utility for HiTOP and RDoC: A commentary on Fisher

This commentary on Fisher (2025) summarises my understanding of the proposal, discusses some strengths and limitations of staying in the DSM framework, and outlines ideas for building on the foundation of the approach. Namely, using Fisher’s approach as a tool for strengthening the validity and utility of other approaches to conceptualising psychopathology, such as the Hierarchical Taxonomy of Psychopathology (HiTOP) model and the Research Domain Criteria (RDoC).
