With the continuous improvement of medical quality, people's awareness of health has gradually increased. They have put forward higher requirements for medical quality, nursing service quality, and medical care safety. Under the influence of these conditions, the workload and work pressure of clinical nurses continue to increase, and mental health problems become increasingly prominent. According to relevant data, the detection rate of occupational stress among nurses was 100%, and the proportion of nurses who perceived considerable stress was 60.9%, which seriously affected their work efficiency and quality of life. However, the physical and mental health of the frontline nurses working in psychiatric hospitals is not optimistic.
