Abstract: Objective To explore the impact of perceived social support on employment anxiety in medical students,as well as the mediating role of self-efficacy and the moderating role of parental involvement. Methods From March to May 2024,a cluster sampling method was used to select 1 134 medical students studying at a medical college in Ningxia as the survey subjects. The survey was conducted using the perceived social support scale,employment anxiety questionnaire,and general self-efficacy scale,and the data were analyzed. Results The total score of perceived social support,self-efficacy and employment anxiety among 1 134 medical students was （62.32±11.99）,（26.36±6.11） and （76.56±17.53）points,respectively. The perceived social support significantly negatively predicted employment anxiety of medical students（β=-0.333,t=-7.300,P<0.01）,and self-efficacy played a partial mediating role between the two,with a mediating effect value of -0.144,accounting for 30.25% of the total effect. The parental involvement moderated the first half of the mediation model（β=0.025,t=2.336,P<0.05）. Conclusion There is a moderated mediator between perceived social support and employment anxiety among medical students,with self-efficacy as the mediating variable,and parental involvement can enhance the impact of perceived social support on self-efficacy.
