The oblimax, promax, maxplane, and Harris-Kaiser techniques are compared. (Author)

The usefulness of the Woodcock-Johnson Psycho-Educational Battery (W-J) to assess learning disabled (LD) children was assessed. The W-J factor clusters could not be replicated with this LD sample, and little evidence was found of the validity of either the cognitive factor clusters or the aptitude factor clusters.

Maternal alcohol use in mid-pregnancy was significantly related to poorer habituation and increased low arousal in newborn infants, even after adjusting for smoking and caffeine use by mothers, maternal age and nutrition during pregnancy, sex and age of the infant, and obstetric medication.

Data from the responses of 104 medical and rehabilitation students to the Attitudes toward Disabled Persons Scale-Form B (ATDP-B) were factor analyzed using a principal components solution, with particular attention to the problem of the number of factors to retain. Research supports ATDP-B use as a unidimensional measure. (Author/PN)

Revised the Counselor Rating Form (CRF) creating the Counselor Rating Form-Short version (CRF-S). Tested reliability and validity of the CRF-S. Results indicated reliabilities of CRF-S scales were comparable to those for the CRF. Factor analytic comparison showed three correlated factors corresponding to the attractiveness, expertness, and…

Eight formula-based estimates of population squared cross-validity and nine estimates of factor scores were compared with estimates from the conventional cross-validation procedure. Burket's and Rozeboom's formula-based estimates of population squared cross-validity in combination with a factor score method offer the most for practitioners…

Factor analyzed Wechsler Intelligence Scale for Children-Revised scores of low-IQ youths aged 9-11 and 14-16. Extracted Verbal Comprehension, Perceptual Organization and Freedom From Distractibility dimensions for each group. Coefficients of congruence indicated the two age groups were not similar on the Freedom From Distractibility factor.…

Using three samples of children--a heterogeneous group, a hyperactive group, and a replication sample of hyperactive children--evaluted the Stony Brook Scale (SBS). Results indicated the SBS independently assessed hyperactivity and aggression in samples of hyperactive children. (Author/RC)

Obtained a hierarchical factor solution on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest intercorrelations for the nine age groups included in the standardization sample. Findings support the validity of the WAIS-R as a measure of general intelligence and the validity of maintaining separate Verbal and Performance IQs. (Author)

Leadership repertoires of public school superintendents are analyzed in terms of the Humanistic Leadership Model. Factor analysis was used to uncover four leadership dimensions. (Author/RL)

Evaluated the dyadic adjustment scale by reconsidering the factor structure of the scale and its subscales using a maximum likelihood, confirmatory factor-analysis procedure. Studied a new sample from the same geographical area. High reliability was confirmed for the overall scale. (Author)

This study tests the degree of factor invariance and factor structure replicability of the Family Environment Interview Schedule. Samples of families from different locations were used. Four interpretable factors were derived. Evidence suggests that the four factor solution was invariant across both samples with an identical factor structure.…

Studies on visual, musical, and speech perception abilities were used to construct auditory ability tests. Correlation and factorial analyses indicated separate capacities for auditory verbal comprehension, auditory immediate memory, temporal tracking, auditory cognition of relationships, discrimination among sound patterns, speech perception…

A 30-item measure of self-esteem in social situations was developed. Factor analysis revealed that a single general factor accounted for 39.7 percent of the total variance. Reliability data based on 128 subjects and normative data based on 265 subjects are provided. (Author/BW)

This article summarizes results from studies of the organization and development of cognitive abilities in adults aged 20 to 60 years old. Theories of intelligence stipulating a hierarchy of intellectual functions, with fluid and crystallized intelligence at the top, are supported. Six conclusions on age differences are offered.
