Research On The Influence Mechanism Of Work Stress On Mental Health Of Wuhan Police Under The Normal Prevention And Control Of Covid-19

【Purpose】 With the normalization of the prevention and control of COVD-19,the current state of mental health of frontline health care workers in the normalization of epidemic prevention and control has been focused on in the past,neglecting the group of public security civilian police who also have the task of prevention and control.Therefore,the purpose of this study was to investigate the effect of work stress on the mental health level of public security civilian police during the new coronary pneumonia epidemic,especially the differences in mental health level by different demographic information.Also,this study explored the boundary conditions of the effect of work stress on mental health,i.e.,the moderating role of civilian police officers’ perceptions of the risk of the epidemic.【Method】 Based on the interactive stress theory,this study surveyed 358 grassroots civilian police officers in Wuhan by means of an online questionnaire and invited them to fill out the Work Stress Scale,SCL-90 Scale,and Epidemic Risk Perception Scale,and collected the corresponding demographic information of the public security police officers,obtaining a total of 302 valid samples.This study further revealed the sample profile through descriptive statistical analysis,and revealed the differences in mental health(SCL-90),work stress,and epidemic risk perception scores by different demographic characteristics through ANOVA.The association between work stress,mental health(SCL-90)and epidemic risk perceptions was explored by correlation analysis.The effect of work stress on mental health(SCL-90 total score and sub-dimensions)was further validated by regression analysis.Finally,this study verified the moderating effect of epidemic risk perceptions in public security police through moderating analysis.【Results】(1)37.75% of public security police had a total score of 160 and above,26.82% had a total mean score of 2 and above,38.74% had a number of positive items of43 and above,and the overall mental health level of the police was not satisfactory.(2)Different demographic characteristics of public security police officers had significant differences in SCL-90 scores,work stress scores,and epidemic risk perception scores(P<0.05).(3)The work stress and epidemic risk perception scores of public security police officers were significantly and positively correlated with the total SCL-90 score and each dimension score(P<0.001).(4)Work stress during the epidemic had a significant positive impact on the SCL-90 total scores of the police(β=0.540,P<0.001),and the higher the work stress,the worse the psychological health of the police.(5)The perception of epidemic risk among public security civilian police moderated the negative impact of work stress on mental health.The main manifestation was that the higher the work stress,the higher the civilian police scored on the three SCL-90 subdimensions of somatization(t=2.199,P<0.05),terror(t=2.01,P<0.05),and paranoia(t=2.04,P<0.05)in the context of high risk perceptions of the epidemic.【Conclusions】 This study shows that the higher the work stress of civilian police,the greater the negative impact on mental health,while establishing a reasonable risk perception can help moderate the negative impact of work stress on mental health.
