Psychological resilience and perceived stress among Chinese medical students: mediation between optimistic intelligence quotient and adversity quotient.

Background: Chinese medical students face rigorous academic demands and exacting professional challenges, which lead to significant psychological stress. Understanding perceived stress and psychological resilience is key to enhancing emotional regulation and empathy. This study explores the hypothesis that psychological resilience impacts the perceived stress of medical students, with the Optimistic Intelligence Quotient (OQ) and the Adversity Quotient (AQ) acting as serial mediators, thereby promoting students' mental health.
