ABSTRACT
WE have seen, in the previous section, how the questionnaires of Cattell, Eysenck and Guilford line up with respect to one another when each is scored in terms of a number of a priori scales, and the derived scales from the three questionnaires are factored in a single analysis. In this section we describe separate analyses for each of the questionnaires and, in a subsequent section, we will describe an analysis in which factors common to the three questionnaire batteries are determined. This two-stage process enables comparison to be made across questionnaires and requires neither that we factor all 322 questions within a single analysis, (this was not technically feasible at the time the analyses were carried out), or that we define our factors on an a priori basis as in the analysis described above.
