Objective  To investigate the psychological resilience of medical staff participating in nucleic acid sampling outside hospital during the COVID-19 epidemic and its influence factors.

  Methods  A total of 197 medical staff in a general tertiary hospital in Guangzhou, Guangdong were selected by convenience sampling method and survey with the general data questionnaire, the Connor-Davidson Resilience Scale (CD-RISC), the General Self-Efficacy Scale (GSES) and the Simplified Coping Style Questionnaire (SCSQ). Statistical analysis was performed using multiple linear regression analysis.

  Results  The total score of resilience of these staff was (69.95 ± 12.85) points. Correlation analysis showed that there was a positive correlation between psychological resilience and positive response, self-efficacy(P < 0.01). The multiple linear regression analysis showed that: compared with medical staff without professional titles, medical staff with intermediate professional title or above had a high level of psychological flexibility(β = 0.150, 0.145, P < 0.05);compared with medical staff with sampling time less than 4 h, the psychological resilience level of those with sampling time longer than 4 h was lower(β = -0.143, P < 0.05);the medical staff who can respond positively had higher psychological resilience (β = 0.422, P < 0.01); and the medical staff with higher levels of self-efficacy had higher psychological resilience (β = 0.296, P < 0.01).

  Conclusions  Medical staff participating in nucleic acid sampling during the COVID-19 epidemic had low psychological resilience. Managers should improve the emergency management mechanism, strengthen the relevant knowledge training and timely psychological counseling to promote their physical and mental health.
