A comparison of four personality inventories

The equivalence of personality constructs measured by four rationally devised inventories watested by means of a factor analytic approach. The tests were administered to large high school and college samples. Separate analysis of each inventory were followed by analysis of pooled scales representing each factor found in any inventory. Twelve dimensions were found to be common to two or more inventories and consistent across the two samples. The results indicate a convergence on a set of basic personality constructs measurable and equivalent in several inventories.
