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...

The present study examined trajectories of individual Diagnostic and Statistical Manual of Mental Disorders (4th ed.) symptoms of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) across the preschool years in children with ADHD. It also evaluated whether preschool symptoms vary in their ability to discriminate children who later meet criteria for ADHD from...

OBJECTIVE The aim of the current study was to identify which subgroups of children with Attention Deficit Hyperactivity Disorder (ADHD) benefitted the most from playing a Serious Game (SG) intervention shown in a randomized trial to improve behavioral outcomes. METHOD Pre-intervention characteristics [i.e., gender, age, intellectual level of functioning, medication use, computer experience, A...

Parent and teacher ratings of child behaviors are often discrepant, and these discrepancies may be correlated with parenting stress. The present study explored whether various parenting stress factors are associated with discrepancies between parent and teacher ratings of attention-deficit/hyperactivity disorder and oppositional defiant disorder (ODD) as well as internalizing symptoms in presch...

Previous studies examining the covariation among Attention Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD) have yielded inconsistent results. Some studies have concluded that the covariation among these symptoms is due to common genetic influences, whereas others have found a common environmental overlap. The present study investigated the ge...

BACKGROUND Not much is known about low mood and its associates in child psychiatric patients. In this study, we examined the prevalence of low mood, how it associates with disruptive behaviour, and affects clinician-rated global functioning in child psychiatric outpatients. METHODS The study population consisted of 862 5-12 year-old child psychiatric patients. The study sample was a subsample...

Play tasks that use standardized procedures and materials are a practical way to assess parenting skills, child behaviors, and the ways in which parents and children interact. We describe a systematic process for developing the parent-child play task (PCPT) to assess mother-child interactions for a randomized controlled trial of a video-based parenting program. Participants were 307 mothers and...

The Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5) workgroup for disruptive behavior disorders is considering adopting a frequency threshold for symptoms of oppositional defiant disorder (ODD). In the present study, the impact of substituting the term "often" with a specific age-based frequency on impairment and prognosis among preschool children was tested in a l...

BACKGROUND To assess the co-occurrence in deviant trajectories of parent-rated symptoms of conduct disorder (CD), oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) from age 4 to 18 years old in a general population sample of Dutch children. METHODS Developmental trajectories of CD, ODD, and ADHD were estimated in a sample of 1,016 males and 1,060 females....

CONTEXT Most adults with a psychiatric disorder first met diagnostic criteria during childhood and/or adolescence, yet specific homotypic and heterotypic patterns of prediction have not been firmly established. OBJECTIVE To establish which childhood and adolescent psychiatric disorders predict particular young adult disorders when accounting for comorbidities, disaggregating similar disorders...
