Explains factor analysis, discussing its relation to other multivariate techniques and describing characteristics of the data to consider in determining the appropriateness of factor analysis. Reviews considerations in making decisions about communality estimates, factor extraction, the number of factors to rotate, methods of factor rotation,…

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…

Analyzed choices made by researchers concerning factor model, retention criteria, rotation, interpretation of factors and other issues relevant to factor analysis. Results indicate that choices made by researchers have generally been poor and that reporting practices have not allowed for informed review, cumulation of results, or replicability.…

The factor structure of the Revised-Children's Manifest Anxiety Scale was investigated for a sample of 106 children attending public school classes for the learning disabled. Strong support was found for the existence of three original subscale factors and the General Anxiety factor for the LD children. (Author/CL)

A generalized congruence maximization procedure for the case of m matrices is presented. The orthogonal rotation procedure simultaneously maximizes the sums of all coefficients of congruence between corresponding factors of m factor matrices. (NSF)

Beliefs about memories and about the ability to recall memories may affect the individual's recollection of facts and "events." What people believe about memory is investigated using previously analyzed and reported responses to the Beliefs about Memory Survey (BMS). The survey sample (N=1046) was randomly divided for calibration and…

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…

This paper presents an exploratory factor analysis of the Spiritual Well-Being (SWB) Scale, which was developed to examine overall life satisfaction. It is a 20-item, self-report instrument that measures three dimensions: an overall Spiritual Well-Being score, a Religious Well-Being score, and an Existential Well-Being score. The findings show…

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 primary purpose of this study was to compare the performance of three procedures to assess dimensionality that were investigated by R. Nandakumar (1994) at different test conditions to reflect the characteristics of language test data. Procedures investigated were nonlinear factor analysis, the procedure of P. Holland and P. Rosenbaum, and W.…

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)

Analyzed parataxic distortion (low self esteem and attribution of low self-acceptance to the average person), by looking for key qualities of parenting associated with this type of distorted perception. (DP)

In line with the latent trait model, the continuous response level is defined and considered, in contrast to the discrete response levels, which have already been explored by the author. (Editor)

Study was undertaken to assess the factorial validity of the RSAP by comparing the original scales with empirically determined ones. (Authors)

College students were given the 16 Personality Factor Questionnaire, the Guilford Zimmerman Spatial Orientation and Spatial Visualization Tests, and the Bender Gestalt. Analyses revealed that personality characteristics were related to Bender performance and that the Bender was not measuring a unitary dimension of behavior. (Author)
