Further evidence is provided for assessing the use of cluster analysis in comparison with other multivariate methods. When appropriately used, cluster analysis is a convenient tool for developing empirically based diagnostic groupings. The frequently stated limitations of the technique should not invalidate the obtained groupings of such cases.…

An empirically based paradigm for assessment and taxonomy of child, adolescent, and young adult behavioral and emotional problems is outlined, and the standardization procedures used to assess problems reported by different informants for large clinical samples are discussed. The application of the paradigm to new cases is considered. (SLD)

This essay notes the complexities inherent in classifying pervasive developmental disorders (PDD), especially when a single classification scheme is to be used for clinical, research, and administrative purposes. The paper considers principles of classification, symptomatology, the neuropsychiatric interface, the value of a multiaxial approach,…

This review of studies of early onset schizophrenia examines the nosological similarity between adult and early onset schizophrenia, differential diagnosis, treatment, and the extent to which children and adolescents diagnosed as having schizophrenia using adult criteria have the characteristic adult correlates. The paper discusses gender…

This paper postulates that cultural and societal factors have exerted a powerful force on the conceptualization and treatment of attention-deficit hyperactivity disorder. A functional assessment approach is presented, along with a model for classifying performance deficits and methods for selecting intervention strategies based on the model.…

Forty parents of children with autism or pervasive developmental disorder completed the Wing Subgroups Questionnaire, developed for subclassifying children into one of L.

Major diagnostic criteria are body temperature and mental status. Management protocol includes fluid and fuel replacement, temperature correction, and leg cramp treatment. (Author/SM)

This article critically analyzes available definitions of learning disability. The general problem of definition is discussed first, followed by a discussion of individual definitions from the earliest to the latest. It is concluded that the definitions fail to provide substantive insight into the nature of the condition. (Contains extensive…

Connections between current and historical autism-specific behavior reported using the Autism Diagnostic Interview-Revised were investigated using 93 subjects showing autistic behaviors. The association was high, although there was a tendency for diagnostic exclusion of adolescents and adults, especially verbal, high-functioning individuals who…

A comparison of 46 language-delayed and 62 normal language onset children examined whether early language delay would predict autistic symptomatology in children diagnosed with autism when young and at an older age. Results found that early language delays predicted more autistic symptomatology when young, but not at an older age. (Author/CR)

School refusal behavior is a common problem seen by mental health professionals and by educators but little consensus is available as to its classification, assessment, and treatment. This study assessed 143 youth with primary school refusal behavior and their parents to examine diagnoses that are most commonly associated with proposed functions…

Methods: A random sample of 211 children from the CCC 2000 was investigated when the children were 1 1/2 years of age. The prevalence and associates of mental health problems and…

An exploratory study of structured and unstructured play was conducted with a small number of severely disturbed and normal children 9 to 13 years of age. Specifically, the investigators characterized psychopathology from a cognitive-developmental perspective by focusing on the Piagetian "scheme" and its manifestation in the play and…
