Analyzing the mental health status of prison police officers,including burnout,anxiety,and depression,and exploring the reasons behind it.Through offline questionnaire surveys with police officers from 12 prisons across 6 provinces,we collected 612 valid responses using burnout scale,anxiety scale,depression scale,and work stress scale,and conducted univariate and correlation analyses,using multiple linear regression analysis for influencing factors.The survey shows that female prison police officers experience more severe depression compared to their male counterparts.Rest conditions,night shift arrangements,and frequency of physical exercise have significant impacts on feelings of burnout,anxiety levels,depression,and stress perceptions.Significant changes were observed in various dimensions before and after 10 years of service.Multiple regression analysis indicates that work stress levels and anxiety levels are the main factors affecting emotional exhaustion among prison police officers.Anxiety levels are the primary factor influencing denationalization among prison police officers,while depressive state is the main factor affecting their sense of achievement.The study suggests adopting scientific scheduling,leveraging technology for police work,providing psychological support,and optimizing management to reduce anxiety and depression,and prevent job burnout.Special attention should be paid to the mental health of female officers and prison officers with over 10 years of service.
