Objective  To investigate the mental health risk factors of nursing professional interns, in order to improve the risk control ability and psychological literacy of nursing professional interns, and then propose effective methods for identifying the mental health risks of nursing professional interns.

  Methods  Totally 200 nursing interns from a university in Shangluo City were studied and their mental health risk was surveyed with self-designed questionnaire based on literature and field research. The data was analyzed with factor analysis method, and the weight of each index of mental health risk was obtained after normalization. The mental health risk was comprehensively assessed with the risk rating form set by the experts. Finally, the corresponding psychological interventions was carried out, a group by precise psychological intervention and another group by routine psychological care.

  Results  Finally 183 valid questionnaires were collected with response rate of 91.04%. A total of 13 representative indicators were extracted from five dimensions: risk cognition (weight 0.436), risk psychology (weight 0.206), epidemic prevention and risk avoidance ability (weight 0.174), emotion regulation(weight 0.121) and safety tendency(weight 0.063). The comprehensive risk assessment score of 183 nursing interns was 0.64, and specifically risk cognition 0.41, emotion regulation 0.61, safety tendency 0.62, risk psychology 0.74 and epidemic prevention and risk avoidance ability 0.76. Based on the risk rating level, these nursing interns were assessed as 2 people with level 1, 21 people with level 2, 37 people with level 3, 75 people with level 4, 44 people with level 5, 3 people with level 6 and 1 person with level 7. After the psychological intervention, the control ability and psychological quality of the two groups were improved, but the effect in precise psychological intervention group was significantly higher.

  Conclusion  The nursing intern had great mental health risk. In view of the high-risk factors, we should carefully conduct the psychological assessment of high-risk students to improve the refined level of mental health education. In the future, we should monitor psychological risk data dynamically, and focus on the training and guidance of risk psychology and epidemic prevention and avoidance capabilities to further improve effectiveness of mental health risk prevention and control.
