Results were quite similar for each of the factor analytic procedures, an indication of a strong underlying structure of the WPPSI tests. Regardless of the factor analytic technique used, two factors appeared--one clearly verbal and the other clearly performance--at each of the three age levels. (Authors)

The present study was designed to examine the construct validity, reliability, item difficulties, discrimination indices, effectiveness and efficiency of the CCAT test. (Author)

The factorial validity of the Iowa Tests of Basic Skills was investigated. Hierarchical factor analysis was performed with a subset of the standardization data to explore the presence of second-order group factors. Results supported the construct validity of Language and Mathematics subscales. Verbal and Visual Information group factors were…

Purpose of this study was to determine the reproduciblity of the RSAP factor structure in college samples. (Authors)

Aims of this study were to determine whether the factor structure produced in earlier research by Kear-Colwell (1973, 1977) on the Wechsler Memory Scale could be replicated in a non-patient population (most research uses patient populations) and also to examine the effects of age, sex, and social class on the performance of normal adults on this…

The attitudes of 600 second year and fifth year grammar school pupils towards their school subjects were investigated using a repertory grid developed specifically for this purpose. (Editor)

Results of the battery of verbal divergent thinking tests differed markedly between the sexes and the test battery showed superior validity among girls. (Author/CB)

Results of the investigation suggest that the facet-factorial approach can be an effective technique for the construction of rating scales to measure complex behavior such as music performance. (Author)
