Factor structures of student ratings of instruction resulting from total group, between group, and within group analyses were compared. Six factors obtained from responses by students to 31 items were used to approximate the between group covariance matrix based on 437 classroom means and the pooled within classroom covariance matrix.

The effect of perceptual speed on performance and paper-and-pencil measures of spatial ability is examined. Perceptual speed is defined as speed in comparing figures or symbols, scanning to find figures or symbols, or carrying out other very simple tasks involving visual perception. It was hypothesized that perceptual speed would have more…

A classification of factors that go into the complex process of reading or learning to read is presented. These factors are listed in outline format under the following sections: (1) sensory input, (2) mediating activity, (3) response, (4) reward and/or motivation, (5) knowledge of results, (6) reward variations, (7) rate of reading, (8) practice…

Personality dimensions in the Jesness Inventory among black male delinquents were identified. A principal components factor analysis with a varimax rotation identified three factors: (1) Self-Estrangement, (2) Social Isolation, and (3) Immaturity. The results suggest that the factors might be a part of a larger alienation construct in black…

A factor replication procedure (FACTOREP) was evaluated using four psychometrically equivalent synthetic correlation matrices containing an imposed three-subscale structure. Comparisons of the structure revealed by two, three, four, and nine-factor rotations using the FACTOREP showed that only the three factor solutions were replicable across all…

This study analyzed the internal consistency and factorial composition of the Job Stress Questionnaire (JSQ) and compared its factor structure across three occupational groups as well. The results indicated acceptable reliabilities for three of four subscales while factor analysis revealed limited support for the factorial validity of the…

Investigated the factor structure of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) for incarcerated individuals (N=234). Coefficients of congruence between the current factors and those of the WAIS-R standardization sample indicated a high degree of correspondence. (Author/BL)

Pattern and level of performance on the WAIS-R (Wechsler Adult Intelligence Scale Revised) and the Luria-Nebraska's Intelligence, Memory, and Motor Scales were examined for 93 neurologically impaired adults. Each set of procedures evidently is indexing the same theoretical constructs. (Author/ABB)

Analyses were performed by sex on four waves of panel data from high school and college-age cohorts, using adolescent/college-age data as well as data from young adulthood, and on multiple subsamples of adolescents who participated in the 1978 National Study of Adolescent Drinking. Results showed one common factor, unconventionality, accounts for…

Investigated higher-order factors in the Interpersonal Style Inventory in male (N=144) and female (N=173) high school students. Analysis of the 15 scale intercorrelations disclosed five dimensions in each sample. The advantage of higher level factors lies in their greater generality and generally higher predictive validities.

A study was conducted to examine how principal components analysis (PCA) and Profile Analysis via Multidimensional Scaling (PAMS) can be used to diagnose individuals observed score profiles in terms of core profile patterns identified by each method. The standardization sample from the Wechsler Intelligence Scale for Children, Third Edition…

Real world data often fail to meet the underlying assumption of population normality. The Rank Transformation (RT) procedure has been recommended as an alternative to the parametric factorial analysis of Covariance (ANCOVA). The purpose of this study was to compare the Type I error and power properties of the RT ANCOVA to the parametric procedures…

The first purpose of this study was to analyze the results of the confirmatory factor analyses, via EQS, with regard to the latent structures of the Learning and Study Strategies Inventory (LASSI) (C. Weinstein, D. Palmer, and A. Schulte, 1987) as proposed by S. Olejnik and S. Nist (1992), A. Olivarez and M. Tallent-Runnels (1994), B. Olaussen and…

The Children's Personality Questionnaire was used to classify 10-12-year-old children into high-and-low stable groups. Factor analysis for the two groups revealed separate factor structures. (ST)

Purpose of this paper is to advance the use of measures of association patterned after omega squared in factorial and repeated analysis of variance designs by simplifying the computational procedure through use of a set of generalized rules. (Authors)
