A construct validation of the Objective-Analytic Test Battery (OATB)

The scales of Cattell's Objective–Analytic Test Battery (OATB) and the factors derived from the factor analysis of the subtests of the OATB were located with respect to a wide range of ability and personality variables, including the 16PF and Cattell's Comprehensive Ability Battery. The expected relationships between the OATB scales and the personality measures did not emerge. However, it was found that many of the OATB scales were highly correlated with ability factors. It is concluded that in Britain, and in its present form, the OATB is not a viable instrument for measuring personality traits.
