It is shown how partial covariance, part and partial correlation, and regression weights can be estimated and tested for significance by means of a factor analytic model. Comparable partial covariance, correlations, and regression weights have identical significance tests. (Author)

An example demonstrates that Joreskog's suggested sufficient conditions for identifying unknown parameters in a confirmatory factor analytic model with correlated factors are not sufficient. Sufficient conditions are presented. (Author/JKS)

Factor analysis of ratings of rehabilitation concepts across semantic differential scales indicated physically disabled adults connotatively structure their worlds along three major dimensions: attractiveness, dynamism, and morality. Potential theoretical implications are discussed. Descriptive information on factors of meaning extracted and…

Discusses differences in results of factor analyses of ten diverse samples which have been studied using the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Concludes that a single common factor structure accounts for the intercorrelations among NBAS items. (Author/BH)

Reports an approach to the development of more effective diffusion strategies, using as a basis the personality variable "change orientation" of educators. An attempt is made to demonstrate that change orientation is a measurable characteristic of teachers. Suggests that the concept holds considerable promise for state-level leaders who…

This article examines the factor structure of two measures of self-concept routinely used with elementary school children: the Coopersmith Self-Esteem Inventory and the Self-Concept and Motivation Inventory. (Author)

Investigates the level of academic alienation in college students and the reliability, validity, and interrelationships between the five academic alienation variables investigated. (Author/IRT)

The construct validity of the Hooper Visual Organization Test (VOT) (H. Hooper, 1983) was studied by comparing it to conceptually similar and dissimilar cognitive abilities in a principal components analysis of results from 240 participants with cognitive impairment. Results suggest that the VOT is best considered a measure of visual-spatial…

The Wechsler Intelligence Scale for Children-Third Edition (WISC-III) was factor analyzed with a sample of 106 deaf and hard-of-hearing children. Two factors emerged, labeled "Language Comprehension" and "Visual-Spatial Orientation." Implications and future directions for the assessment of deaf and hearing-impaired students are…

Presents results of an exploratory factor analysis of the mathematics self-efficacy scale. Results, based on 522 undergraduates from three different colleges, indicate that the scale is a multidimensional measure of math self-efficacy with reliable subscales. Four first-order factors were identified, suggesting that the scale taps different…

Data from the General Social Survey for 1977 (n=1,303) and 1991 (n=430) are used to examine the stability of attitudes toward abortion and women's roles. Findings support the hypothesis that public attitudes toward discretionary abortion and nontraditional sex roles are discrete but correlated sets of attitudes that remained stable from 1977 to…

Investigated interactions between stress level of syllables and articulatory difficulty as influences on children's early words. Subjects were 32 two-year olds asked to imitate nonsense words and syllables that varied in articulatory difficulty. Found that both factors had significant effects on aspects of children's imitations. (MOK)

Examined the relative performance of two commonly used methods of parameter estimation in factor analysis, maximum likelihood (ML) and ordinary least squares (OLS) through simulation. In situations with a moderate amount of error, ML often failed to recover the weak factor while OLS succeeded. Also presented an example using empirical data. (SLD)

States there are good reasons to believe that teachers' views about the nature of science can form part of the hidden curriculum in their science teaching. Explores views captured using case study and survey methodologies. Finds case studies showed depth and subtlety of some teachers' views of science and interviews were consistent with survey…
