The purpose of this study was to determine whether an association exists between neuropsychological deficits and conduct disorder (CD) with and without concurrent attention-deficit-hyperactivity disorder (ADHD). In addition, we explored the differential neuropsychological performance of aggressive and nonaggressive CD adolescents and the combined effect of(More)
Although young children with conduct disorder (CD) are suspected of having verbal and executive function deficits, most studies that investigated this hypothesis did not control for attention deficit hyperactivity disorder (ADHD). Furthermore, relatively little is known about the interaction between cognitive deficits and familial factors in explaining the(More)

Data were drawn from an ongoing longitudinal(More)
Contemporary studies suggest that most of the children who manifest conducts disorder also present personal as well as family problems. This is particularly true for children whose disorder is precocious. The identification of personal characteristics as well as social and family risk and protection factors associated with children with such problems are of(More)
OBJECTIVE Co-occurring oppositional defiant disorder and conduct disorder symptoms are particularly common, which could be related to the greater severity (number and nature of symptoms) of each disorder.
