“…We considered several child-specific and peer processes as potential external validators of identified profiles. Specifically, we examined CU behaviors, given that the presence of CU traits with conduct problems may represent a distinct subtype of youth who are at increased risk for a more severe and persistent trajectory of conduct problems and antisocial behavior, higher levels of negative contextual correlates, and less responsiveness to intervention than youth with conduct problems without CU traits (Colins, Fanti, & Andershed, 2020;Fanti & Kimonis, 2013;Frick, 2012;Pardini, Stepp, Hipwell, Stouthamer-Loeber, & Loeber, 2012). More specifically for the present study, the relations among conduct problems and the neurobiological and cognitive factors that we considered often vary based on the presence of CU traits, suggesting that CU traits may indicate differential risk (Blair, 2015;Frick, 2012;Hwang et al, 2016;Lozier et al, 2014;Martin-Key et al, 2018).…”
