The Additive Value of Positive Psychological Capital in Predicting Work Attitudes and Behaviors

Conventional wisdom and recent research have supported the importance of employee positivity. However, empirical analysis has not yet demonstrated potential added value of recently recognized psychological capital over the more established positive traits in predicting work attitudes and behaviors. This study found that psychological capital was positively related to extrarole organizational citizenship behaviors (OCBs) and negatively to organizational cynicism, intentions to quit, and counterproductive workplace behaviors. With one exception, psychological capital also predicted unique variance in these outcomes beyond demographics, self-evaluation, personality, and person—organization and person—job fit. The article concludes with implications for future research and practical application.
