In this study, 322 college students were investigated with the Self-Regulation Fatigue Scale,
the General Self-Efficacy Scale, and the Pro-Social Behavior Scale to explore the effects of self depletion
on prosocial behavior and the mediating role of self-efficacy. The results showed that: (1) Self depletion
significantly negatively predict prosocial behavior, controlling for variables such as gender, age, place of
birth and whether or not the student was an only child; (2) Self depletion also indirectly predicts prosocial
behavior through the mediating effect of self-efficacy. The present study reveals the relationship between
self depletion and prosocial behavior and its underlying mechanisms, which enriches the research related
to self-efficacy.
