An investigation was conducted of the displayed biobehavioral states of 5 students (ages 8-20) with profound mental retardation. Results indicated that state level can be reliably specified and that overall state characteristics can be used to classify subjects according to profile groups. (Author/JDD)

The validity of intuitive classifications of experienced diagnosticians was examined for 10 experienced diagnosticians evaluating child behavior problems. Results showed that intuitive prototypes corresponded poorly with empirical core syndromes in the assessment system of T. M. Achenbach and others. Reasons for differences are discussed. (SLD)

Relative prevalence of stereotyped behaviors was studied with 246 children and adults with developmental disabilities. Two staff members completed a 54-item checklist assessing stereotyped behaviors, abnormal focused affections, compulsions, rigidity, savant skills, and defensiveness. Factor analyses produced weak evidence for a general stereotypy…

This document presents Part I of a two-part study which sought to ascertain the relationship of grade level, achievement level, sex, and method of presentation to the various bases by which children classify geometric concepts. Two tasks, administered consecutively to 96 subjects in grades five, eight and eleven, consisted of the sequential…

This document, Part II of a two-part study, is the summary chapter of a report which sought to ascertain the relationship of grade level, achievement level, sex, and method of presentation to the various bases by which children classify geometric concepts. Two tasks, administered consecutively to 96 subjects in grades five, eight, and eleven,…

An empirical typology of behavior styles was developed to define distinct variations of healthy, marginal, at-risk, and maladjusted behavior using a stratified national sample of 1,400 youths aged 5 to 17 years. Results are compared with recent epidemiological studies, and application of the typology is demonstrated. (SLD)

A study attempted to replicate a previous study that presented reliability data from recordings of behavior state using a 13-category coding system. Replication was unsuccessful. Obtained mean percentage agreement on occurrence for individual behavior state and participants (n=34) ranged across observer pairs from 0 to 58 percent. (Contains 13…

Assessed was the degree to which classification of mental retardation levels based upon a measure of adaptive behavior (the Vineland Social Maturity Scale) differed from the classification based upon IQ for Negro and Caucasian children, 4 to 17 years of age. (Author)

Evaluated was the extent to which psychologists and physicians made use of a measure of adaptive behavior in the classification of 100 mentally retarded children (5 to 16 years of age) during a 10 year period. (Author/MC)

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)

A cluster analytic study was conducted to derive behaviorally homogeneous subtypes of pervasive developmental disorders (PDD) based on a range of behavioral symptoms that characterize autism. Analysis of data on 34 children with PDD, 27 of whom met criteria for autism, indicated 4 distinct groups differing on independent measures of social,…

Developed a brief behavior rating scale consisting of 28 items divided into seven categories for use in a school setting. Test validity was based upon the successful discrimination between neurologically impaired, socially maladjusted, emotionally handicapped, and normal children. (Author)

A sorting-recall procedure was used to examine the relationship between study and recall organization in reflective and impulsive children at the first and fourth grade levels. Data regarding sorting latencies per trial and the number of trials required to achieve stable sorts were provided by two indirect measures of the deliberateness and ease…

Psychopathology in outpatient children was explored using two classification systems. Clinically derived Diagnostic and Statistical Manual of Mental Disorders (Third Edition, Revised) (DSM-III R) diagnoses in three high frequency diagnostic groups were compared to empirically derived Child Behavior Checklist (CBCL) scores for an overall sample of…
