“…However, variable-centered research often assumes that the association of one domain (e.g., reading skills) and later academic achievement is similar across the entire population of children, regardless of their level of competence in other domains (e.g., social skills). More recently, subgroup approaches that emphasize patterns among variables in the prediction of child development outcomes have become popular (e.g., Bellanti & Bierman, 2000;Farmer, Bierman, & The Conduct Problems Prevention Research Group, 2002;Lanza, Rhoades, Greenberg, Cox, & Family Life Project Key Investigators, 2011;Rhoades, Greenberg, Lanza, & Blair, 2011;Stormshak & Bierman, 1998). These approaches are aimed at identifying particular constellations of characteristics that describe subgroups of children (Bergman & Magnusson, 1997;Lewin, 1931) and thus account for the complex, interactional nature of the multiple factors that contribute to children's development (Laursen & Hoff, 2006).…”
