“…Research indicates that patterns of disruptive behaviour are fairly stable over time, with continuity between disruptive and aggressive behaviour in early childhood and in later childhood (Broidy et al, 2003;Snyder, Prichard, Schrepferman, Patrick, & Stoolmiller, 2004). Additionally, children whose behaviour styles show the highest levels of aggression may be the most likely to show stability of these maladaptive behaviours (Majdandžić & van den Boom, 2007). Studies on the longitudinal trajectories of internalizing behaviours indicate that these behaviours are less stable, with variation found according to the rater and risk factors accounted for (Keiley, Bates, Dodge, & Petit, 2000;Sterba, Prinstein, & Cox, 2007).…”
