Psychometric requirements for behavioural personality tests

Abstract

So-called psychometric personality theories give the basis for quantifying individual differences, where as Ribes´s behavioural personality theory furnishes the elements necessary to quantify within-individual consistency. Both theories suppose coherence in the behavior of the individual over time and in diverse situations. The different arms followed explain differences in the proposed tests for personality assessment. They refer to tests of differentiated characteristics which provide data of a different nature and which are analyzed by different statistical techniques. Our thesis is that, despite these differences, both types of tests must meet the requirements for reliability and validity all psychological tests.
