Abstract
The unprecedented and prolonged coronavirus disease 2019 (COVID-19) pandemic has escalated the gravity of disasters in the field of mental health. Nurses are health care providers who play a pivotal role in all phases of disaster management and psychiatric nurses are required to be prepared and equipped with competencies to respond to such disasters. This cross-sectional study aimed to investigate the effects of mental health nurses’ professional quality of life on disaster nursing competencies. This study adhered to the STROBE checklist for observational research. Data were collected from 196 mental health nurses working in various settings, including hospitals and communities in South Korea. Compassion satisfaction and compassion fatigue were measured using the Korean version of the Professional Quality of Life Scale. Disaster nursing competencies were measured using the Disaster Nursing Preparedness-Response Competencies Scale. Multiple regression analysis showed that compassion satisfaction (β = 0.36, P < 0.001) was the most potent predictor of disaster nursing competencies of mental health nurses, followed by participation in disaster nursing (β = 0.15, P = 0.023) and disaster nursing-related education (β = 0.15, P = 0.026); these factors explained 30.1% of the variance. Education programmes ensuring that mental health nurses are adequately prepared for disaster management should include theoretical content as well as simulation training using virtual situations that resemble actual disasters. Further, supportive leadership and work environments that encourage cohesive teamwork are needed to increase compassion satisfaction of nurses.
