A common problem in practical educational research is that of perfect scores which result when latent trait models are used. A simple procedure for managing the perfect and zero response problem encountered in converting test scores into measures is presented. It allows the test user to chose among two or three reasonable finite representations of…

The primary purpose of this study was to provide evidence for or against the construct validity of the Career Skills Assessment Program (CSAP) instrument. A secondary purpose was to present a systematic procedure for carrying out internal construct validity studies in any testing instrument. Construct validation using confirmatory factor analysis…

The usefulness of path analysis as a means of better understanding various linear models is demonstrated. First, two linear models are presented in matrix form using linear structural relations (LISREL) notation. The two models, regression and factor analysis, are shown to be identical although the research question and data matrix to which these…

Factor structure underlying responses to the 373-item MMPI was found to be essentially identical to the factor structure previously defined from analysis of intercorrelations among the first 168 items. (Author)

A factor analysis of the Coleman Report data on Equality of Educational Opportunity is used to suggest several hypotheses about the nature of interactions affecting educational production functions. These hypotheses were used in the specification of a simultaneous equation regression model of the educational process. (Author/EH)

Earlier research based on 81 Occupational Reinforcer Patterns (ORPs) suggested a nine-category classification of occupations. The present research, based on 148 ORPs, investigated the ability of that classificatory system to assimilate new information. (Authors)

The present study is an attempt to explore the possible interaction between self concept and visual perception in relationship to reading disabilities. (Author)

Described is a method for obtaining an oblique simple structure in which primary axes are principal axes of homogeneous subsets of test variables. Examples of its application in R and Q-type analyses are presented. (Author)

The Illinois Test of Pscyholinguistic Abilities was administered to 167 normal intelligence children (mean age 112 months) and then factor analyzed to determine construct validity and the extent to which each subtest measures a discrete combination of the psycholinguistic dimensions of level, process, and channel.

Holland's hexagonal model for six occupational groups was tested with data on estimated occupational rewards. Data on rated occupational reward characteristics were available for 148 occupations. Although the hexagonal shape was distorted, the groups were arrayed in the order postualted by Holland. (Author)

This paper outlines the use of confirmatory factor analytic techniques to assess the reliability of television program checklists as indicators of television exposure, to estimate the stability of television exposure over time, and to detect patterns of television content preference. A causal model incorporating these three properties was…

This longitudinal study of beginning teachers in Kentucky yields a number of characteristics useful in identifying persons most likely to obtain and retain teaching positions in secondary education. The Western Kentucky University Teacher Preparation Evaluation Program (TPEP), begun in 1971, follows careers of elementary and secondary school…

This study determines major dimensions of social stratification for whites and blacks and explores the existence of distinct social classes. It is based on a survey conducted on 225 white and 206 black household heads in Toledo, Ohio, using a highly structured interview that included variables reflecting major theoretical dimensions of…

Factor analysis of responses of funeral directors to work orientation items is interpreted first as specifying major orientational themes and second as to how well the theoretical value components of professionalism and a business orientation hold together empirically. (Author)
