  • Optimism predicting employees' creativity: The mediating role of positive affect and the positivity ratio
    Publication . Rego, Arménio; Sousa, Filipa; Marques, Carla; Pina e Cunha, Miguel
    We examine how optimism predicts creativity both directly and through the mediating role of positive affect and the positivity ratio (the ratio between the frequency of positive and negative affective states). Five hundred and ninety five employees reported their positive and negative affect, as well as their optimism. Their creativity was reported by supervisors. The main findings are the following: (1) optimism predicts creativity both directly and through the mediating role of positive affect and the positivity ratio; (2) the relationship between the positivity ratio and creativity is curvilinear, in such a way that an "excessive" ratio is detrimental to creativity. The findings stress the relevance of optimism both for individuals and organizations, and suggest that examining positivity ratios is fruitful in the creativity domain, as it has been in other domains, and that negative affect should not be viewed simply as an obstacle when studying employees' creativity.

  • Retail employees' self-efficacy and hope predicting their positive affect and creativity
    Publication . Rego, Arménio; Sousa, Filipa; Marques, Carla; Cunha, Miguel Pina E.
    The study shows how retail employees’ self-efficacy and hope predict their creativity, both directly and through the mediating role of positive affect. Five hundred and seven retail employees reported their hope, self-efficacy, and positive affect, their supervisors reporting their creativity. Three main findings are: (1) hope and self-efficacy predict creativity; (2) positive affect also predicts creativity; (3) positive affect partially mediates the relationship between both dimensions of positive psychological capital (self-efficacy and hope), and creativity. The study suggests that retail organizations may foster employees’ creativity by encouraging conditions that cultivate employees’ hope and selfefficacy, as well as their positive affect.
