Doctoral students' academic performance: The mediating role of academic motivation, academic buoyancy, and academic self-efficacy

Understanding influential factors for the academic performance of doctoral students is crucial for supporting their exploration of academic research opportunities and aiding their pursuit of careers in academic research. This study surveyed 659 doctoral students in China, utilizing scales to assess academic motivation, buoyancy, self-efficacy, self-concept, and performance. Based on a partial least squares structural equation modeling (PLS-SEM) analysis, a direct correlation between self-concept and performance was identified. Moreover, motivation, buoyancy, and selfefficacy were significant mediators in the relationship between self-concept and performance. To significantly enhance self-concept's impact on doctoral students' academic performance, educators should endeavor to enhance students' motivation, buoyancy, and self-efficacy. This endeavor will contribute to the discourse on academic performance and its underlying psychological mechanisms.
