Editorial: Roads Less Traveled: New Directions for Novel Outcomes in Youth Irritability Research

Abstract

Road metaphors are ubiquitous in youth mental health. Developmental psychopathology research is described in terms of pathways, trajectories, cascades, and transitions. Children's behavioral concerns are discussed as warning signs and rough spots. Although these metaphors have long been useful abstractions, modern quantitative methods and large-scale longitudinal studies have made it possible to empirically investigate the "roads" traveled by individuals across development. One goal here is to chart the paths most often followed by different subgroups of youth. Another goal involves surveying variables that nudge children toward (or away from) psychopathology and other key outcomes. These 2 goals-finding trajectories and predictors thereof-have important implications for research, intervention, and policy; and some of the most important studies, in our view, accomplish both.
