There is growing consensus that diagnostic labels are insufficient to describe the individual child’s psychiatric profile, much less inform the precise combination of interventions that will minimize the impact of risk and/or bolster protective factors over the course of a particular child’s development. Moreover, investigations of neurobiological and genetic mechanisms associated with psychopathology have revealed considerable cross-diagnostic overlap, undermining the validity of models that propose a 1:1 relationship between risk and psychiatric disorder. Accordingly, recent publications have advocated for neurodevelopmental models that utilize trait-based measurement, as well as increased emphasis on integration of biological and experiential mechanisms. Despite an expanding body of literature supporting this conceptual shift, the practical implications remain unclear. In this special issue, we compile a collection of novel empirical research papers and reviews that build on the trans-diagnostic principles of the RDoC framework.
