We investigated by means of a simulation study how well methods for factor rotation can identify a two-facet simple structure. Samples were generated from orthogonal and oblique two-facet population factor models with 4 (2 factors per facet) to 12 factors (6 factors per facet). Samples drawn from orthogonal populations were submitted to factor…

Multisample confirmatory factor analysis (MCFA) and latent mean structures analysis (LMS) were used to test measurement invariance and latent mean differences on the Kaufman Adolescent and Adult Intelligence Scale[TM] (KAIT) across males and females in the standardization sample. MCFA found that the parameters of the KAIT two-factor model were…

Confirmatory factor analysis was used to reanalyze correlational data from selected variables in Guilford's Aptitudes Research Project. Results indicated Guilford's model reproduced the original correlation matrix more closely than other models. Most of Guilford's tests indicated high loadings on their hypothesized factors. (GDC)

Although some research has examined the factorial nature of the Multidimensional Aptitude Battery (MAB), none has tested hypotheses relevant to both oblique and orthogonal models via confirmatory factor analysis. Thus, in this investigation, a series of models was tested, which compared the model fit of both oblique/higher order models against a…

Studied the constructs underlying the Ball Aptitude Battery (Ball Foundation; BAB) in 3 studies involving 329 and 365 adults and 175 ninth graders and in a reanalysis (study 4) of previous BAB data. Results show that "g" plays a significant but not dominant role in the BAB, which measures abilities needed for assessing person-job fit.…

Whether the one- or two-factor Wechsler or weighted sum scores (WSS) structural models adequately fit the Wechsler Intelligence Scale for Children III (WISC-III) covariance matrices was studied with samples of 2200 and 1118 children from previous studies. Both the WSS and supplemented models provided better fit than Wechsler's model but still…

The Universal Nonverbal Intelligence Test (UNIT) is an individually administered, nonverbal intelligence test designed for use with non-English-speaking, limited English proficient, or deaf children. The aim of this study was to assess the factor structure invariance of the UNIT across deaf and standardization samples through the use of…

Several confirmatory factor analyses were conducted on the Armed Services Vocational Aptitude Battery (ASVAB) with a nationally representative sample of 11,078 subjects. Based on fit indexes, simple structure, and parsimony in parameter estimation, a three-factor hierarchical model was chosen. Two factors resemble those of P. E. Vernon (1969).…

Whether the measurement of intelligence by the Wechsler Intelligence Scale for Children III (WISC-III) differs for children who exhibit inappropriate test-taking behavior was studied empirically with 247 inappropriate behavior and 515 appropriate behavior children. Results suggest that the factor index and full-scale IQ may have different meanings…

Through use of confirmatory maximum likelihood factor analysis in conjunction with the LISREL V computer program, an evaluation was made of the validity of higher-order ability constructs in structure-of-intellect tests all containing semantic content and operations of cognition or evaluation.

Spearman's general intelligence, or "g" factor, was investigated in a sample of 189 Black, 184 Hispanic, and 187 White children aged 6-11. The magnitude and loadings of factors on the Wechsler Intelligence Scale for Children (Revised) were similar for all three groups. (Author/GDC)

Factor-analyzed data are reported from the Kaufman Adolescent and Adult Intelligence Test for 1,535 whites, 226 African Americans, and 140 Hispanics. Factor structures yielded Fluid and Crystallized dimensions that were congruent across race and ethnic groups and provided construct validity for each subsample. (SLD)

Empirical validation of the first-order and higher-order factor structures of the structure-of-intellect (SOI) model was provided by reanalysis of a database of 39 measures administered to 178 Coast Guard Cadets. Results suggest that SOI could be reconceptualized as a pyramid-like hierarchical theory of intelligence. (SLD)
