The validity of the Giotto integrity test

Giotto is a work-based personality questionnaire designed to assess integrity. It contains 101 items and generates scores on seven scales based on the Prudentius model of personality. Because these traits are evaluative in nature, Giotto makes use of an ipsative format in which force choice items are matched for social desirability. The intrinsic non-linearity of the ipsative framework is addressed using neural network programming techniques. Giotto has been standardised on 701 people in a variety of employment positions. Several studies supporting the validity of Giotto are reported.
