Abstract

AbstractBased on the Conservation of Resources theory, we develop dual mechanisms by which lunchtime recovery activities predict creativity. Specifically, by conceptualizing the quality of lunchtime naps and meals as examples of recovery activities, we expect these recovery activities help individuals replenish their psychological resources in the form of more work engagement (affective process) and less cognitive depletion (cognitive process). Further, individuals are expected to utilize these available psychological resources to generate creative ideas. To test our model, we used a group‐mean centering approach to focus on within‐person effects by recruiting 230 employees working at construction sites in South Korea. Overall, after removing 242 invalid observations (omitting at least two items and not reporting the duration of a nap), we finalized a total of two‐wave 1598 daily questionnaires. A high quality of lunchtime naps and meals helps individuals recover their emotional resources (more work engagement) and cognitive resources (less cognitive depletion), which predict individuals' creativity. Finally, although indirect effects of the two recovery activities on creativity via affective and cognitive processes were generally supported, the indirect effect of lunch nap quality on creativity via work engagement was not significant, suggesting most of the effect is due to meal quality rather than nap quality.
