Student engagement of Undergraduate Psychology students in Statistics Courses tends to be low due to the complexity of the topic and the students' negative perception. Internal factors such as perceptions of lecturer behavior and academic self-efficacy can influence student engagement. This study aims to determine the role of academic self-efficacy as a mediator in the relationship between perceived creativity fostering teacher behavior and student engagement among Undergraduate Psychology students in the Statistics Course. The research instruments used were the University Student Engagement Inventory, the Perceived Creativity Fostering Index, and the College Academic Self-Efficacy Scale, which were filled out by a total of 460 respondents. The results showed that academic self-efficacy has a role as a mediator in the relationship between perceived creativity fostering teacher behavior and student engagement. These findings suggest that creativity fostering teacher behavior and academic self-efficacy should be the primary focus for lecturers and the university to improve student engagement among undergraduate Psychology students, especially in the Statistics Course.
