Abstract: Objective To understand the status of work-related rumination and occupational stress in emergency medical dispatchers，explore the relationship between them. Methods From June to September 2021，363 emergency medical dispatchers in cities across China were selected as the research subjects by the convenience sampling method.The general information questionnaire，job content questionnaire and work-related rumination questionnaire were used to conduct a questionnaire survey. Results The average degree of occupational stress（D/C） of 363 emergency medical dispatchers was 1.14±0.17，the score of affective rumination was （15.12±5.24）points，the score of problem-solving rumination was （17.64±4.64）points.The marital statuswas the influencing factor of affective rumination，while age and length of service were the influencing factors of problem-solving rumination. Pearson correlation results showed that there was a negative correlation between the two types of rumination and occupational stress in emergency medical dispatchers（r=-0.155，-0.253，both P<0.01）.The combination of occupational stress and various dimensions predicted affective rumination by 11.4%（F=10.320，P<0.01），and the combination of length of service and social support predicted problem-solving rumination by 16.3%（F=12.716，P<0.01）. Conclusions The occupational stress of emergency medical dispatchers has a significant positive effect on affective rumination，while the occupational stress has no significant effect on problem-solving rumination.The managers can guide employees to form positive rumination and reduce negative rumination by improving work requirements and social support and carrying out mindfulness intervention，so as to maintain their physical and mental health and promote the better development of pre-hospital emergency services.
