Abstract: Objective To examine job burnout status and to explore the impacts of family-work conflict and work-family enrichment on job-burnout among police.Methods Stratified cluster sampling was adopted to choose 2 500 police for the study.Self-administered questionnaires were used to assess job burnout,work-family conflict,family-work conflict and work-family enrichment.Hierarchical linear regression was employed to analyze the relationships between job burnout and personal characteristics,work-family conflict,family-work conflict,and work-family enrichment.Results The indexes of three dimensions of job burnout were emotional exhaustion(17.46±7.54),depersonalization(9.98±5.62),reduced personal accomplishment(16.09±7.26),with a total score of 43.54±13.57.The overall detection rate of burnout was 69.21%.The detection rate of mild,moderate,and severe job-burnout were 38.83%,24.77%,and 5.61%,respectively.The detection rates of emotional exhaustion,depersonalization,reduced personal accomplishment and job-burnout were 17.27%,28.84%,and 45.89%,respectively.Work-family conflict,family-work conflict and work-family enrichment could affect emotional exhaustion,depersonalization,and reduced personal accomplishment,which accounted for 11.7%,14.1%,16.3%,and 23.8%of the increased total variance.Gender,age and job title could stably predict emotional exhaustion.Gender had a negatively stable predictive power for depersonalization.Education and income could stably predict the reduced personal accomplishment.Age,education and job title could stably predict job burnout.Conclusion Work-family facilitation,family-work conflict and work-family enrichment can effectively predict job burnout.
