OBJECTIVE Recent studies indicate that many preschoolers meet diagnostic criteria for psychiatric disorders. However, data on the continuity of these diagnoses are limited, particularly from studies examining a broad range of disorders in community samples. Such studies are necessary to elucidate the validity and clinical significance of psychiatric diagnoses in young children. The authors exam...

OBJECTIVES To describe actigraphically detected and parent-reported sleep problems in nonmedicated children with attention-deficit/hyperactivity disorder (ADHD); to clarify whether or not comorbid oppositional defiant disorder contributes to sleep difficulties; and to compare objectively measured sleep with the parents' observations of sleep. DESIGN Case-control study. SETTING A child and a...

OBJECTIVES The Collaborative Life Skills (CLS) program is a school-home intervention for students with attention-deficit/hyperactivity disorder (ADHD) symptoms and impairment. CLS integrates school, parent, and student treatments followed by booster sessions during a maintenance period into the subsequent school year. The program is delivered by school-based mental health providers. Beneficial ...

Oppositional defiant disorder (ODD) is a common clinical problem in children and adolescents. Oppositionality and associated types of aggressive behavior are among the most common referral problems in child psychiatry. Grouped among the disruptive behavior disorders, ODD is frequently comorbid with other psychiatric conditions and often precedes the development of conduct disorder (CD), substan...

A population-based, randomized universal classroom intervention trial for the prevention of disruptive behavior (i.e., attention-deficit/hyperactivity problems, oppositional defiant problems, and conduct problems) is described. Impact on developmental trajectories in young elementary schoolchildren was studied. Three trajectories were identified in children with high, intermediate, or low level...

BACKGROUND Childhood aggressive antisocial behavior (CD) is one of the strongest predictors of mental health problems and criminal behavior in adulthood. The aims of this study were to describe personality profiles in children with CD, and to determine the strength of association between defined neurodevelopmental symptoms, dimensions of character maturity and CD. METHODS A sample of 1886 chi...

Objective: While DSM-IV Attention-deficit/hyperactivity disorder (ADHD) comorbid with antisocial behaviours identified by DSM-IV conduct disorder (CD) has been claimed as a ‘distinct subtype’, there is less information about the validity of a subtype based on the more prevalent comorbidity of oppositional defiant disorder (ODD). The present study investigated the associations of past ODD with p...

253 A central premise in the “catecholamine hypothesis” of attention-deficit/hyperactivity disorder (ADHD) is that dopamine (DA) dysfunction leads to clinical symptoms. The hypothesis arises, in part, from the clinical efficacy of methylphenidate, as well as evidence from brain imaging studies that suggest reduced activity in frontal-striatal regions. The theory, however, overlooks the phenotyp...
