Attention-deficit/hyperactivity disorder (ADHD) is characterized by high levels of inattention, hyperactivity, and impulsivity; however, these symptoms can result from a variety of reasons. To obtain a comprehensive understanding of the various difficulties of individuals with ADHD, especially when co-occurrence difficulties are present, it is…

Reading disability (RD) and math disability (MD) frequently co-occur, but the etiology of this comorbidity is not well understood. Groups with RD only (N = 241), MD only (N = 183), and RD + MD (N = 188) and a control group with neither disorder (N = 411) completed a battery of measures of internalizing and externalizing psychopathology, social and…

Evaluation of 357 students with either learning disability (LD), serious emotional disturbance (SED), or both (SED/LD), ages 6 to 18, found that children with LD differed from those with SED mainly in terms of severity of problem, not type of problem. Results suggest that students with both LD and SED are under-identified and underserved. (DB)

Evaluation of the relationship between hyperactivity and learning difficulties in 1,593 Australian elementary students indicated twice as many males as females with learning difficulties; 11% of the sample were hyperactive; 41% of the subjects with learning difficulties were also hyperactive; and 3.2% of all subjects had both hyperactivity and…

This study examined consequences of the comorbidity of developmental coordination disorder (DCD) and learning disability (LD) for the severity and pattern of perceptual-motor dysfunction. Compared to children with only DCD, those with DCD and LD had poorer perceptual-motor ability, with particular difficulty performing manual dexterity and balance…

The use of standardized psychoeducational diagnostic instruments to identify learning disabilities was evaluated with 19 students (ages 7 to 13) with sensorineural hearing impairments. Students with hearing impairment were found to demonstrate learning disabilities with a frequency similar to that found in students with normal hearing, suggesting…

This article criticizes the term "comorbidity" used to describe the overlap of developmental syndromes or disorders. Data from 179 school-age children are evaluated for criteria of seven disorders. Since fully 50 percent of the sample met the criteria for at least two diagnoses, the premise that these disorders are discrete categories on…

Clinical and psychoeducational data were analyzed for 119 children (ages 8-16) referred for learning and/or behavior problems. A learning disability was present in 70 percent of children with attention-deficit/hyperactivity disorder. A learning disability in written expression was two times more common than a learning disability in reading, math,…

Noting a high incidence of learning disabilities among students with visual impairments, this article compares definitions of the two conditions. Common assessment approaches are discussed and those inappropriate for students with low vision or blindness are identified. Suggested intervention approaches include adaptation of the environment,…

This article examines issues in the assessment of secondary and postsecondary students who are both learning disabled and hearing impaired. It notes origins of the gap between deaf education and the field of learning disabilities; considers who should evaluate these students; and discusses formal assessments, informal assessments, and use of…

The prevalence of communication disorders in a population of 242 children with learning disabilities between 8 and 12 years of age was determined. A speech, language, or hearing problem was exhibited by 96.2 percent of the children. Only six percent of the children were considered to be receiving appropriate services. (Author/DB)

A discussion of language disorders that often occur with learning disabilities focuses on definitions, characteristics, alternative assessment methods, and service delivery models and interventions. Use of standardized test batteries, curriculum-based language assessment, and portfolio assessment is reviewed. Principles and methods to enhance…

The study investigated the temporal stability and estimated the standard error of measurement for subtests of the Peabody Individual Achievement Test (PIAT) with 60 learning disabled and emotionally handicapped children (9 to 13 years old). (Author/SBH)

The study with 51 boys (ages 7 to 9 years) found that subjects classified as having both attention deficit disorder/hyperactivity and learning disabilities demonstrated the most external locus of control with subjects classified as only learning-disabled intermediate and subjects classified as only having attention deficit disorder/hyperactivity…

Offers a conceptual model for students who manifest symptoms of both learning disabilities and emotional/behavior disorders. The model is based on six functional domains: cognitive processing, social/emotional adjustment, behavioral functioning, academic performance, language functioning, and executive functioning. The model is applied to critical…
