Are the correlates for girls with early-onset conduct problems necessarily the same as for boys? It has been shown that externalizing symptoms such as disruptive, impulsive, hyperactive, inattentive, and overtly aggressive behaviors are important risk factors for boys’ continuing development of ODD and CD, whereas internalizing symptoms are not. In the absence of evidence, one cannot assume that this is equally true for girls.
