Broad versus narrow personality measures and the prediction of behaviour across cultures

Measures of several personality variables, from both within and beyond the domain of the Big Five personality factors, were used to predict a variety of complex behaviour outcomes of some social and cultural significance (e.g. alcohol consumption and grade point average). Analyses focused on replicated predictions across participants in four countries (Canada, England, Germany, and Finland) and on the relative predictive accuracies of narrow trait predictors versus broad factor predictors. The results indicated substantial consistency in those predictions across cultures for several of the criteria. Furthermore, the narrow traits were able to account for more criterion variance than were the broad factors underlying those traits. Our data contraindicate the increasingly common practice of using only a few personality factor measures to predict complex human behaviours. Copyright (C) 2003 John Wiley Sons, Ltd.
