Extant research has shown that grandiose narcissism predicts a wide range of work-related
outcomes. However, despite differentiating in the social-personality literature besides grandiose
narcissism also its vulnerable form, there is little organizational research that would
include both expressions of narcissism, in particular with regard to positive organizational
behaviors, including strengths use and deficit correction in the workplace. In addition, the
role of dark-side personality traits, such as narcissism, in predicting strengths use and deficit
correction in the workplace, in particular in regard to motivational factors, seems understudied.
Accordingly, this study adds to the literature on narcissism in the organizational context
by investigating the direct effects of grandiose and vulnerable narcissism and motivational
orientation in the form of regulatory focus at work on strengths use and deficit correction in
the workplace. Based on a sample of 446 working adults from the Polish population, it was
found that grandiose narcissism positively predicted both strengths use and deficit correction.
In turn, vulnerable narcissism was unrelated to strengths use and deficit correction.
Furthermore, drawing on the distal-proximal model of work-specific regulatory focus, it also
tested whether regulatory focus at work has the incremental validity over grandiose and vulnerable
narcissism in predicting strengths use and deficit correction. The hierarchical
regression analyses indicated that both promotion and prevention focus were positively
associated with strengths use and deficit correction, predicting them beyond grandiose and
vulnerable narcissism. The theoretical and practical implications of this study in the context
of narcissism in the workplace and positive organizational scholarship are discussed.
