Cross-rater agreement on bullying, victimization, and related behaviors of middle school students with and without behavioral disorders (BD) was investigated. Students with BD (n = 11), their peers (n = 90), and general education teachers (n = 10) completed the Peer Relationship Survey (PRS), a non-anonymous measurement scale. The results of…

Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results…

Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

This study investigates the relationship between sensory processing patterns and behavioral patterns in children. The population consisted of all children in Tehran city. Participation included 229 school and 155 preschool children. We collected data using the Sensory Profile School Companion and Conners Teacher Rating Scale. Results showed that…

We investigated autism spectrum disorder (ASD) symptomatology, hyperactivity and affect in seven genetic syndromes; Angelman (AS; n = 104), Cri du Chat (CdCS; 58), Cornelia de Lange (CdLS; 101), Fragile X (FXS; 191), Prader-Willi (PWS; 189), Smith-Magenis (SMS; 42) and Lowe (LS; 56) syndromes (age range 4-51). ASD symptomatology was heightened in…

Over the past 50 years the concept of attention deficit/hyperactivity disorder (ADHD) has developed from the notion of a specific form of brain dysfunction to that of a heterogeneous set of related behaviours. The great advances in genetics, neuroimaging and neuropsychiatry have made it one of the best understood forms of complex mental…

Objective: To compare the morning and afternoon/evening functioning of children with ADHD treated in the community with either atomoxetine or long-acting stimulants and reported to be doing well. Method: 109 8- to 12-year-olds and their mothers participated in one of three groups: stimulants (STIM, N = 26), atomoxetine (ATMX, N = 25), or…

Previous studies suggest that individuals with Williams syndrome (WS), a rare genetically based neurodevelopmental disorder, show specific weaknesses in visual attention and response inhibition within the visuospatial domain. Here we examine the extent to which impairments in attentional control extend to the visuomotor domain using a…

Background: Impaired cognitive control has been frequently observed in children and young people with attention deficit hyperactivity disorder (ADHD) and might underlie the excessive hyperactivity and impulsivity in this population. We investigated behavioural and electrophysiological indices relevant to one domain of cognitive control; namely…

This study examined both the frequency and type of noncompliant behavior in 14 boys with co-occurring Attention-Deficit/Hyperactivity Disorder (ADHD) and oppositional defiant (OD) behavior, 24 boys with only ADHD, and 33 nonproblem boys. Mothers rated boys' noncompliant behavior on the Response Style Questionnaire (RSQ) and observers coded…

Harassment and bullying among 186 students with intellectual disabilities, ages 12 to 21 years, in special education schools were examined. The differences between bullies and victims in terms of social adjustment and social skills were investigated. No prototypes characterizing differences in social skills were found between the three subgroups:…

Despite important clinical and nosological implications, the comorbidity of oppositional defiant disorder (ODD) and generalized anxiety disorder (GAD) has received little attention. A clinic-based sample of 243 boys (ages 6-10 years), their parents, and teachers participated in an evaluation that involved assessments of behavioral, academic, and…

Objective: Children with ADHD experience peer problems that may place them at risk for adverse outcomes. Using a short-term longitudinal design, this study links specific behaviors to peer functioning in groups of previously unfamiliar children with ADHD. Method: The participants were 268 children with ADHD who took part in an intensive summer…

It was found that brain damaged children were more active in structured situations and more distractibile than control group children. These findings pointed to a deficiency in control mechanisms. The correlational data suggested the manner in which these deficiences operate. Sex differences were also discussed. (Author/CG)

Compared child outpatients with diagnoses for both conduct disorder (CD) and attention deficit disorder with hyperactivity (ADD/H) with children with CD but no ADD/H. Children with both CD and ADD/H exhibited more physical aggression and a greater variety and severity of antisocial behaviors despite their younger age at time of referral than did…
