Handwriting execution is based on the cognitive, kinesthetic, motor skills, and manual co-ordination skills of an individual. The deterioration in handwriting quality is a common implication of neurological disorders. Difficulty and degradation in handwriting has been attributed to the sensory motor deficits prevalent in developmental disorders.…

The purpose of this study was to describe the motor, attention and intellectual characteristics of a population-based sample of children first screened for motor impairment and to discuss the recruitment and identification methods employed. A two stage cross-sectional, school-based survey was conducted to screen for children with motor…

As the "Behavioral Assessment System for Children, Second Edition" ("BASC-2") is often used to aid in diagnosis it is important to discern how children and adolescents with Autism Spectrum Disorder (ASD) score on the "BASC-2" compared to typically developing controls. This study compared scores of typically developing…

The aim was to characterize the panorama of developmental disorders in 208 preschool children with a clinical diagnosis of autism spectrum disorder (ASD), referred to a specialized centre, the Autism Centre for Young Children (ACYC), for intervention. At the centre, a research team examined all children according to structured protocols and…

Background: To test whether the retrospective reporting of the age of onset impairment criterion for attention deficit/hyperactivity disorder (ADHD) required in the "Diagnostic and Statistical Manual of Mental Disorders-IV" (DSM-IV) complicates identification of new and known child and adolescent cases later in life. Methods: A birth-records-based…

Classification of arithmetic disorders is predicated on neuropsychological features and associated learning disabilities. Assesses the compatibility of these classifications on a nonreferred, population-based cohort of children (N=139) with developmental dyscalculia. Concludes that children with dyscalculia and disabilities in reading and/or…

The Ozawa Behavioral Rating Scale contains six items related to distractibility and nine items related to impulsivity. This validity study showed that the Scale shows statistically significant relationships with the Wechsler Intelligence Scale for Children--Revised and the Matching Familiar Figures Test and may be appropriate for identifying…

A study investigated the incidence of attention deficit hyperactivity disorder in 86 adults with severe mental retardation. Using the Diagnostic and Statistical Manual of Mental Disorders, 15% of the sample met the diagnostic criteria. This measure was not influenced by chronological age, adaptive age, IQ, or gender. (Author/CR)

A study involving 103 children (ages 5-17) examined the clinical utility of the ADHD Symptom Checklist-4 (ADHD-SC4), a screening measure for attention-deficit/hyperactivity disorder (ADHD). Findings support the internal consistency and validity of the ADHD-SC4 as a screening instrument for ADHD, oppositional defiant disorder, and aggressive…

This paper presents results of analyses of a questionnaire constructed for parents to detect student motivational problems and behavior patterns which may suggest an attention deficit disorder. Cross tabulations and analyses of variance demonstrated the scale's power to identify children with attention deficits. (DB)

A survey of 1 school district found 136 students (out of 14,229) with attention deficit-hyperactivity disorder (ADHD) of which 77 were receiving special education services; 40 were also identified as behavior disordered, 22 as learning disabled, and 7 as mildly mentally retarded. Fifty students were in general education classrooms with resource…

The purposes of this study were to: (1) identify the educational characteristics of children with Attention Deficit Hyperactivity Disorder (ADHD) and Undifferentiated Attention Deficit Disorder (UADD); and (2) to discuss the clinical implications of the current DSM-III-R diagnostic procedures of these disorders. Specifically, the differences in…

Graphomotor output was assessed in children with attentional problems using the Repeated Patterns Test (RPT). Forty-eight subjects, ages 8 to 13, who met standard criteria for Attention Deficit Hyperactivity Disorder (ADHD), participated, of whom 24 had primarily Inattentive Type and 24 had Combined Type ADHD. Both groups had intact visuomotor…

This study examined the prevalence of Attention Deficit Hyperactivity Disorder (ADHD) among school children in Arkansas for the purpose of helping school districts plan appropriate educational interventions. The ADHD Survey was mailed to all 311 school superintendents; 128 surveys were returned. Findings revealed that, overall, 3 percent of…

This paper presents a model of differential diagnosis of attentional problems and reading disability that uses intra-individual differences in performance of tasks that vary in their requirement of sustained attention such as listening comprehension (high attention requirement) and reading comprehension (lower attention requirement). The validity…
