How depression affects academic self-efficacy among college students: the mediating effect of professional identity and the moderating effect of belief in a just world

Academic self-efficacy has a significant impact on college students' academic performance and growth and success. To explore the effects of depression on academic self-efficacy and the mediating role of professional identity and the moderating role of belief in a just world among college students. The Depression Scale, Academic Self-Efficacy Scale, Professional Identity Scale, and Belief id a Just World Scale were used to investigate 3270 college students. (1) depression negatively predicts academic self-efficacy among college students; (2) professional identity partially mediates the relationship between depression and academic self-efficacy; (3) belief in a just world positively moderates the pathways of influence of depression and academic self-efficacy. Specifically, the negative predictive effect of depression on academic self-efficacy was weaker among college students with high belief in a just world compared to the group with low belief in a just world. There is a mediating effect between depression and academic self-efficacy interventions. Meanwhile, professional identity is a mediating variable in the relationship, and belief in a just world mitigates the negative effects of depression on academic self-efficacy.
