This study reports new evidence for the dimensionality and validity of the Learning Behaviors Scale in samples of Head Start children. A sample of 900 former Head Start children enrolled in public kindergarten and first-grade classrooms was studied using modern techniques to analyze item responses represented as ordered categories. Findings from…

Given the importance of accurately gauging early childhood approaches to learning, this study reports evidence for the dimensionality and utility of the Preschool Learning Behaviors Scale for use with disadvantaged preschool children. Data from a large (N = 1,666) sample representative of urban Head Start classrooms revealed three reliable…

Some researchers have argued that discrepant broad index scores invalidate IQs, but others have questioned the fundamental logic of that argument. To resolve this debate, the present study used a nationally representative sample of children (N = 1,200) who were matched individually for IQ. Children with significantly uneven broad index score…

The present study identified higher order relationships among teacher assessments of approaches to learning and emotional and behavioral adjustment constructs for low-income urban preschool children. It examined the unique contribution of these dimensions to cognitive and social competencies and risk of poor academic outcomes. Analyses of a large…

This study examined the unique protective influence of center-based early care and education experiences on kindergarten outcomes for children entering public school kindergarten. The 3,969 participants were geographically and demographically representative of an entire kindergarten cohort in a large urban school district. Child age, gender,…

The aim of this study was to derive core profiles from the general education subsample from the Comprehensive Test of Nonverbal Intelligence (CTONI) using a three-stage cluster analysis procedure. Findings indicate that level, not shape, differences should be expected from administration of the CTONI to students both with and without learning…

Evaluates the criterion-related validity of unusual subtest profiles from the Differential Ability Scales. Participants were a large cohort stratified in proportion to United States Census data. Children with unusual profiles were identified and matched to controls. Two groups were compared across a variety of criteria. No group differences were…

Reports on empirical studies that assessed continuing claims for utility of subtest analysis. Hierarchical regression and discriminate models were used to determine maximum potential of ability subtests to explain variation in academic achievement, stylistic classroom learning, and test-session behavior. Ipsative subtest scores provide no…

Compares various base-rate procedures with statistical-significance testing approach used by psychologists. Nonlinear multivariate method is used to determine whether children with a learning disability or emotional disturbance are more likely to show unusual subtest patterns than are children from the normative sample of Wechsler Intelligence…

Examines WAIS-R profiles of 194 college students diagnosed with learning disabilities (LD) to assess where they yield unique and interpretable profiles. Results show nearly 94% match profiles found in the WASI-R standardization sample. Also, shapes fail to explain a significant proportion of variation in student academic skills. (Author/JDM)

Syndrome scores for the normative school-age population of the revised Bristol Social Adjustment Guides were grouped according to sequential hierarchical cluster analyses. Sixteen homogeneous syndromic profile types emerged and are described in this article (Author/BW)

Found most representative subtest profiles for 1,200 children comprising standardization sample of Wechsler Preschool and Primary Scale of Intelligence (WPPSI). Grouped scaled scores from WPPSI subtests according to similar level and shape using sequential minimum-variance cluster analysis with independent replications. Obtained final solution of…

Study identifies most representative ability and achievement for the Linking sample (N=824) of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and the Wechsler Individual Achievement Test (WIAT). Primary benefit of core-profile typology is that it provides contrasts for testing multivariate IQ-achievement discrepancies. Two…
