The current study examined the psychometric properties and factor structure of the Multidimensional Anxiety Scale for Children (MASC) among a community sample of 118 African American students (58 females; ages 14-19 years; mean age = 15.79) in an urban, parochial high school. Adolescents completed the MASC and several other self-report measures of…

This paper reviews the basic processes of exploratory factor analysis (EFA) with regard to evaluating test score validity. Construct validity is the focus of the paper. The similarity between the processes of construct validation and EFA is described and the use of EFA as a tool to explore score validity is explored. Factor analysis is a method…

A generalized matrix procedure is developed for computing the proportionate contribution of a factor, either orthogonal or oblique, to the total common variance of a factor solution. (Author)

Correlations between environment measures and mental ability tests scores presented by Marjoribanks were examined for the presence of factors common between the two sets of measures. A single latent common factor was found to account for all but a small portion of the total variance. (Author/SE)

Recently, interest in research measuring stream of consciousness or thought has increased. A study was conducted, based on a previous study by Hurlburt, Lech, and Saltman, in which subjects were randomly interrupted to rate their thoughts and moods on a Likert-type scale. Thought samples were collected from 27 subjects who carried random-tone…

To replicate and extend Grey's (1981, 1985) studies involving junior-high school students, "How Is Your Logic?" (a 26-item, Piagetian-based, group-administered written test of cognitive development) was given to 553 subjects, 10 through 48 years of age. Each item of the test measured either a specific concrete operation or a specific…

The Kaiser Measures of Sampling Adequacy (MSA) were derived for a typical six-concept Semantic Differential. The overall indices indicated that both concept and total correlation matrices would lead to comparable decisions regarding the psychometric quality of the sample data sets. The individual MSA's, however, revealed considerable variability…

The purpose of this research was to study the feasibility of estimating the major CPI factors directly from CPI scale scores and to determine whether such estimates of factor scores could be used to formulate personality types. (Author)
