The need to grow: Developmental considerations and challenges for modern psychiatric taxonomies.

Recently proposed psychiatric taxonomies and classification systems, Research Domain Criteria (RDoC) and the Hierarchical Taxonomy of Psychopathology (HiTOP), aim to structure symptoms of psychopathology along a common set of dimensions. Hierarchical dimensional models of psychopathology are empirically supported and facilitate more productive research on disorder etiology and course. Lacking in these modern approaches, however, is a thoughtful integration of developmental context and considerations. In this brief commentary, we argue for (a) the importance of structural models of personality and psychopathology to advance an understanding of psychopathology development and etiology, (b) important considerations for measurement and assessment from a developmental perspective, and (c) the importance of taking more seriously the hard work of developmental taxonomic research.
