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. (Author/RD)

The responses of 322 beginning first graders to the six subtests of the Metropolitan Readiness Test were factor analyzed. A single General Readiness factor appeared to best describe the instrument. Implications for use of the Metropolitan Readiness Test are briefly discussed. (Author)

Finds that one factor of the "Preschool Attainment Record" (PAR) accounts for 69 percent of the variance, indicating the need for standardization of the PAR. (RL)

The Wechsler Adult Intelligence Scale (WAIS) and 20 tests from the French Kit were administered to over 100 undergraduates. Analyses revealed ten factors: verbal comprehension, visualization, memory span, syllogistic reasoning, general reasoning, induction, mechanical knowledge, number facility, spatial orientation, and associative memory.…

No meaningful differences were found for four ethnic groups (black, Spanish, Jewish, Caucasian-Gentile) in the factor structures of the CEEB Comparative Guidance and Placement Programs Battery, thus confirming its cross-ethnic factorial validity. Thus it is recommended for use in counseling and placement functions even in institutions having…

Scores on the Career Decision-Making Self-Efficacy Scale for 418 underprepared undergraduates were analyzed to determine component structure. Two distinct components for underprepared students were identified: information gathering and decision making, which accounted for 60% of variance among scale items. (SK)
