Abstract: | Integrating the dynamic self‐regulatory framework with the motivational self‐regulation perspective, we theorize and test how and when creative self‐efficacy increases individual creativity at the within‐person level. Conceptualizing creative process engagement as a self‐regulation effort, we theorize that creative process engagement mediates the within‐person effect of creative self‐efficacy on individual creativity. We further explore how creative self‐efficacy and chronic regulatory focus interact to affect the within‐person mediating effect. A sample of 145 R&D workers provided two monthly reports for their creative activities and experiences over 8 months. The findings provide empirical support for the hypothesized mediating mechanism. At the within‐person level, creative process engagement mediates the relationship between creative self‐efficacy and individual creativity. The results also show that chronic regulatory focus moderated the mediated relationship. Specifically, creative self‐efficacy is positively related to individual creativity for employees with a strong prevention focus and negatively related to individual creativity for employees with a strong promotion focus. |
