Abstract
This study investigated the mediating effect of engineering design self-efficacy on the relationship between self-leadership and perceived team creativity. Participants were 110 engineering college students pursuing team projects. Engineering design self-efficacy showed complete mediation effects on the relationships between perceived team creativity and self-reward and evaluating beliefs and assumptions. Partial mediation effect of engineering design self-efficacy was found on the relationship between perceived team creativity and natural reward. Finally, limitations of this study and suggestions for future studies were discussed.
