Abstract
In the domain of measurement of personality by questionnaire, the last decade has been one of integration. At least among the designers of factored scales, if not among others, there have been attempts systematically to discover the common factor space and the relative standing of the various scales therein (Cattell, 1973; Comrey & Duffy, 1968; Derman & Harman, 1973; Eysenck & Eysenck, 1968).
