Regarding conduct disorder (CD) Marsee and Frick (2005) wrote:

Research on the development of conduct problems has uncovered a large number of risk factors associated with CD. These risk factors include dispositional characteristics located within the child (e.g. biological abnormalities, predisposing personality traits, cognitive deficits), as well as factors involving the child's social context (e.g. dysfunctional parenting practices, peer rejection, impoverished living conditions). Research suggests that risk factors have a cumulative effect on the development of problem behavior, with risk increasing in a linear manner from the presence of no risk factors to the presence of six or more risk factors (p. 292).
