Benefits and limitations of structural equation models for multivariate experiments with incomplete data are presented. Examples from studies of latent variable path models of cognitive performance illustrate analyses with latent variables, omitted variables, randomly missing data, and nonrandomly missing data. (SLD)

Describes exploratory and confirmatory analyses of verbal-performance procedures to illustrate concepts and procedures for analysis of correlated factors. Argues that, based on convergent and discriminant validity criteria, factors should have higher correlations with variables that they purport to measure than with other variables. Discusses…

Offers alternative analyses and interpretations of Macmann and Barnett's research data and results. Contends that intelligence is complex and that intelligence testing is important component of school psychological practice. Discusses relation and frequent inconsistency between research and practice. (CRR)

Tested one-, two-, three-, and four-factor models within normal and psychiatric adolescent inpatient groups to confirm the factor structure for the Wechsler Intelligence Scale for Children-Revised (WISC-R). For both samples, the Kaufman three-factor solution had the best overall fit of the WISC-R subtest covariance structure. Other models were…

A modification of Horn's parallel analysis is introduced that is based on the Monte Carlo simulation of the null distributions of the eigenvalues generated from a population correlation identity matrix. This modification reduces the tendency of the parallel analysis procedure to overextract or to extract poorly defined factors. (SLD)

The concordance and factor structures of the Beck Depression Inventory and the Hamilton Rating Scale for Depression were evaluated with 259 outpatients being treated for depression. The two scales were significantly correlated and assessed similar rates of improvement at multiple assessment points, but emphasized different dimensions of…

Data from the Family Needs Survey, provided by 53 mothers of young children with disabilities, were subject to both classical test theory analyses and factor analysis. Results suggest that the Family Needs Survey yields reasonably valid data regarding family needs. (Author/JDD)

A factor analysis was conducted for a sample of 200 white and Hispanic children (ages 6-11) using the Wechsler Intelligence Scale for Children-Revised. Results indicated that the two-factor solution was similar for the two groups, but there were notable differences for the three-factor solution, relative measures of "g," and subtest…

Dimensional measures of aspects of personality disorders (PD) were developed. Convergence of these measures with the "Big Five" personality factors was studied in 300 general population subjects. Results suggest substantial similarity between the five factors and PD measures, though the latter cannot be entirely subsumed by the Big Five…

Several methods for the analysis of three-way data (data classified three ways) are described and shown to be variants of principal components analysis of the two-way supermatrix in which each two-way slice is strung out into a column vector. Direct fitting and fitting derived data are considered. (SLD)

Administered Expectations About Counseling-Brief Form (EAC-B) to 153 college students to examine instrument's factorial validity. Students also completed Developing Purpose section of the Student Development Task Inventory, second edition; the Counseling Readiness Scale; and the Career Counseling Diagnostic Inventory. Results support the factorial…

Compares coverage of five subjects in eight daily newspapers, employing both factor analysis and Pearson correlations. Computes correlation coefficients among newspapers by using (1) size of individual stories as items; and (2) space measurements by categories. Finds that different ways of coding the same raw data produced different results. (SR)

Teacher morale in Singapore is explored by means of a questionnaire administered to 415 teachers in 10 secondary schools, and, 4 months later, to 305 teachers in 6 other secondary schools. Analysis suggests that items cluster around three factors: (1) leadership synergy; (2) cohesive pride; and (3) personal challenge. (10 references) (MLF)

The fundamental mathematical model of L. L. Thurstone's common factor analysis is reviewed, and basic covariance matrices of maximum likelihood factor analysis and alpha factor analysis are presented. The methods are compared in terms of computational and scaling contrasts. Weighting and the appropriate number of common factors are considered.…

Intervention strategies for use with students with mild learning and behavior problems were rated by 232 teachers and were factor analyzed, resulting in 5 factors for intervention use (principal involvement, teacher intervention, special education, teacher consultation, and parent involvement) and 5 for reasonability (teacher intervention,…
