Poverty is a well-established risk factor for behavior problems, yet our understanding of putative family mediators during early childhood (i.e., before age 5 years) is limited. The present study investigated whether the association between poverty and behavior problems during early childhood is mediated simultaneously by perceived parenting,…

The present longitudinal study aimed to investigate the influence of ADHD symptoms on reading development in elementary schoolchildren. To this end, repeated assessments of ADHD symptoms (teacher ratings of inattention, hyperactivity, and impulsivity) and reading achievement (standardized tests of decoding speed and text comprehension) were…

Objective: To examine externalizing behavior problems and cigarette smoking as predictors of subsequent cannabis use. Method: Dutch adolescents (N = 1,606; 854 girls and 752 boys) from the TRacking Adolescents' Individual Lives Survey (TRAILS) ongoing longitudinal study were examined at baseline (ages 10-12 [T1]) and at two follow-up assessments…

The need to assess Diagnostic and Statistical Manual, Fourth Edition (DSM-IV) disorders in children younger than 7 years of age has intensified as clinical efforts to diagnose and treat this population have increased, and clinical research on psychopathology has advanced. A new diagnostic instrument for young children was created, the Diagnostic…

Objective: This study investigated the association between preschool children's sleep patterns measured by actigraphy and parent-reported hyperactivity symptoms. Many previous studies have reported sleep problems in children with attention deficit hyperactivity disorder (ADHD)-like symptoms. Methods: This study examined a cross-sectional sample of…

The present study examined how vulnerability and protective factors at the individual level (child's disabilities; patterns of attachment), and at the family level (fathers'/mothers' affect), help explain differences in socioemotional and behavioural adjustment among children aged 8-12 years with comorbid learning disability (LD) and attention…

In a prospective study of developmental outcomes in relation to early-life otitis media, behavioral, cognitive, and language measures were administered to a large, diverse sample of children at 2, 3, 4, 6, and 9-11 years of age (N = 741). At 9-11 years of age, 9% of the children were categorized as having attention-deficit/hyperactivity disorder…

Introduction: Most behavior checklists for attention problems or attention deficit/hyperactivity disorder (ADHD) such as the Child Behavior Checklist (CBCL) have a narrow range of scores, focusing on the extent to which problems are present. It has been proposed that measuring attention on a continuum, from positive attention skills to attention…

The Tourette's Disorder Scales (Shytle et al., 2003) are parent- (Tourette's Disorder Scales-Parent Rated; TODS-PR) and clinician-rated (Tourette's Disorder Scales-Clinician Rated; TODS-CR) measures that assess tics, obsessions, compulsions, inattention, hyperactivity, aggression, and emotional disturbances among children with tics. Although the…

The nature of the co-occurrence of chronic tic disorders (CTD) and attention deficit hyperactivity disorder (ADHD) is unclear. Especially in the field of psychopathology, the relationship of CTD and ADHD remains to be clarified. Thus, the aim of the present chart review study was to specify the contribution of CTD and/or ADHD to the…

Inattention/hyperactivity is a childhood outcome of low birth weight. However, the mechanisms by which low birth weight leads to inattention/hyperactivity are unclear. This study examined arousal, activation, motor speed, and motor coordination as possible mechanisms, attending to sex differences. 823 children (400 males) from Detroit and…

Objective: To explore the contributions of genetic and environmental influences to individual variation and covariation of the Child Behavior Checklist (CBCL) DSM-oriented scales (DOS) originally proposed by Achenbach and associates in 2001. Method: A classic twin study of 398 twin pairs ages 8 to 17 years belonging to the population-based Italian…

The fields of child psychology and psychiatry have not yet established the clinical presentation in school of children and adolescents who have been diagnosed as having a depressive disorder. To address this issue, the authors used teacher ratings on scale oriented to the third, revised edition of the "Diagnostic and Statistical Manual of…

The reliability of Attention-Deficit/Hyperactivity Disorder (ADHD) rating scales in children with mental retardation was assessed. Parents, teachers, and teaching assistants completed ADHD rating scales on 48 children aged 5-12 diagnosed with mental retardation. Measures included the Child Behavior Checklist (CBCL), Conners Rating Scales, the…

Background: The appropriateness of the "Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition" (DSM-IV) nosology for classifying preschool mental health disturbances continues to be debated. To inform this debate, we investigate whether preschool psychopathology shows differentiation along diagnostically specific lines…
