The 15FQ+ is a normative, trichotomous response, personality test that has been developed as an update to the original 15FQ. The 15FQ is based on 15 of the 16 core personality dimensions that were first developed by Cattell and his colleagues in 1946. The 15FQ applies Cattell’s personality dimensions directly to the workplace. This provides a more occupational orientated personality test as an alternative to the 'Sixteen Personality Factor'* series of tests which are traditionally more clinically based. Since its development in 1991 the 15FQ has been used widely throughout the world and enhances its reputations as one of the most well researched assessments of normal personality available today.
The 15FQ+ incorporates the same 15 core personality factors as in the 15FQ as well as a number of recent psychometric innovations. The 15FQ+ includes the additional measure of Factor B (intelligence) which was originally excluded from the first edition of the 15FQ.
