Primary care physicians who treat attention-deficit/hyperactivity disorder (ADHD) may expect to encounter oppositional defiant disorder (ODD) in about half of patients with ADHD. Up to 20% of patients with ADHD may meet criteria for conduct disorder (CD), and a higher percentage will exhibit aggressiveness or other symptoms of CD without meeting full diagnostic criteria. Primary care physicians...

The efficacy of the Incredible Years parent and child training programs is established in children diagnosed with oppositional defiant disorder but not among young children whose primary diagnosis is attention-deficit/hyperactivity disorder (ADHD). We conducted a randomized control trial evaluating the combined parent and child program interventions among 99 children diagnosed with ADHD (ages 4...

This study tested whether proactive and reactive aggression were differently predictive of later externalizing problems such as delinquency and DSM-related disruptive behaviors (i.e. oppositional defiant and conduct disorders). It also tested whether these two subtypes of aggressive behaviors interacted in predicting externalizing problems. A community sample of low SES boys participated in the...

To assess the effects of postnatal parental smoking on subsequent parent and teacher ratings of DSM-IV attention deficit hyperactivity disorder (ADHD) symptoms and oppositional behaviors in children diagnosed with ADHD and their siblings. Children between 5 and 12 years of age with ADHD and their siblings were included. DSM-IV ADHD symptom subscales (Inattentive and hyperactive-impulsive), and ...

OBJECTIVE We wished to ascertain if there is an association between symptoms of attention-deficit/hyperactivity disorder (ADHD) and home environment in children with ADHD and non-ADHD siblings, controlling for other environmental measures. METHODS 96 children with ADHD combined type (ADHD-CT) and their siblings participated in the study. Parent and teacher Conners' rating scales were complete...

BACKGROUND The concept of differential susceptibility has challenged the potential meaning of personal traits such as poor ability to regulate emotions. Under the traditional model of diathesis/stress, personal characteristics such as liability to angry outbursts are seen as essentially disadvantageous, emerging under duress in a way that is maladaptive. In contrast, with differential susceptib...

Background: We have limited knowledge of the impact of attention-deficit/hyperactivity disorder (ADHD) symptoms on the daily functioning of young preschool children. Objective: This study investigated the level of impairment related to symptoms of ADHD in different functional domains. It also addressed how impairment caused by ADHD was related to ADHD subtype, symptom load, gender, and the cooc...

Measurement invariance (metric/scalar) of oppositional defiant disorder (ODD) dimensions (negative affect, oppositional behaviour, and antagonistic behaviour) across sex and informants is tested. Parents and teachers of 622 preschool children from the general population answered a dimensional measure of ODD. ODD dimensions function similarly in boys and girls. Some differences were found by inf...
