Background: Extensive research has identified risk factors for problem behaviour in childhood. However, most of this research has focused on isolated variables, ignoring possible additive influences. The purpose of this study was to examine whether risk factors for problem behaviour act in a cumulative manner, and to investigate whether cumulative…

Background: Twin studies of childhood behavior problems support the conclusion that individual differences in impulsivity, hyperactivity, and inattention are largely due to genetic influences. Non-genetic variation is due to environmental influences that are unique to the individual, and possibly to rater contrast effects. In the present…

In this study, the author examined the relationship between theory-of-mind understanding and preschool-aged children's peer-related social competence. One hundred eleven 3- to 5-year-old children (48 boys, 63 girls) participated in 2 theory-of-mind tasks designed to assess their understanding of false belief. Teachers rated children's peer-related…

Objective: To determine factors influencing the use of outpatient mental health services provided by mental health professionals (OMHS) for children in foster care using a national probability sample in the United States. Method: As part of the National Survey of Child and Adolescent Well-being, detailed survey data were collected on 462 children,…

Discrete trial training (DTT) is a well-established intervention for teaching skills to children with autism; however, few published guidelines are available for determining whether a child's rate of learning a particular skill is satisfactory and, if not, what to do. We assert that progress within 8-10 teaching sessions usually is evidence of…

We explore the neurobiological bases of attention deficit hyperactivity disorder (ADHD) from the viewpoint of the neurochemistry and psychopharmacology of the catecholamine-based behavioural systems. The contributions of dopamine (DA) and noradrenaline (NA) neurotransmission to the motor and cognitive symptoms of ADHD (e.g. hyperactivity, variable…

The aim of the study reported here was to establish whether the behavioural profiles of children with high-functioning autism (HFA) come to approximate the profile of children with Asperger Syndrome (AS) over time. The parents of 21 children with HFA and 19 children with AS, all aged between five and 11 years and matched on chronological and…

Parents and educators around the country are concerned about the amount of time children watch television. Part of this concern stems from the fact that a considerable amount of violence is regularly portrayed on television. In addition, those youngsters who watch an excessive amount of television have little time for developing other interests…

Effective child-behavior management is an important characteristic in facilitating positive parent and child interaction. The current study examines the impact of a behavioral parent-training group methodology on problem behaviors and goals for a single mother and two young boys. Results indicate that the procedures were valuable for enhancing…

This article describes a type of intervention with parents that attempts to stimulate and encourage empathic imagination in relation to their child's difficult behaviour. Some barriers to this process are explored in the context of wider cultural influences, particularly as they pertain to the USA. Basic cultural assumptions about children, their…

Asian and Euro-American parents of preschool-aged children were interviewed concerning their beliefs about the nature and purpose of play; they also completed two questionnaires and a diary of their children's daily activities. The children's teachers were interviewed and provided information about the behaviour of the children in preschool. The…

This study examined teachers' behavioral ratings of young children (ages 5 and 6) with and without attention-deficit/hyperactivity disorder (ADHD). A study group consisting of 30 children with formal diagnoses of ADHD and a comparison group of 30 children without ADHD were developed using randomized matching procedures. Teachers of these children…

Background: Behavioural and emotional problems occur at a high rate in children and adolescents with intellectual disability, often from a young age. Some studies have indicated that children and adolescents with autism present with even higher rates. Less is known about the presentation, development and family impact of these difficulties in…

This longitudinal monozygotic (MZ) twin differences study explored associations between birthweight and early family environment and teacher-rated behaviour problems and academic achievement at age 7. MZ differences in anxiety, hyperactivity, conduct problems, peer problems and academic achievement correlated significantly with MZ differences in…

This study examined whether extremely high life satisfaction was associated with adaptive functioning or maladaptive functioning. Six hundred ninety-eight secondary level students completed the Students' Life Satisfaction Scale [Huebner, 1991a, School Psychology International, 12, pp. 231-240], Youth Self-Report of the Child Behavior Checklist…
