Personality at home vs. work: Does framing for work increase predictive validity of the Dark Triad on work outcomes?

In a between subject design 903 people completed a robust Dark Triad and a Big Five trait measure and each group was asked to report their behaviour in two situations: at work or in general. Those individuals that were asked to think of work when reporting their personality reported behaviour that was more Extraverted, Conscientious, more Emotional Stable and less Machiavellian. Unexpectedly, there was no difference for Narcissism and Psychopathy. Gender differences were smaller in the work group than the non-work group suggesting situation may moderate gender differences in personality. Implications and limitations are acknowledged.
