Mediating Effect of Firefighters' Resilience and Public Service Motivation Regarding the Influence of Depression on Their Work Engagement During COVID-19

In this study, we aimed to investigate the influence of resilience or public service motivation (PSM) on firefighters' work engagement during the coronavirus disease (COVID-19) pandemic. We conducted an online survey with 304 firefighters assigned to Gyeonggi-do between October 27 and 28, 2022, and collected their demographic information; work-related data; mood, anxiety and insomnia symptoms; and work-related attitudes. The leading causes of firefighters' stress were physical and mental health decline due to heavy workloads (46.4%), verbal abuse and assault from civilians (33.9%), conflict with coworkers (18.4%), and death of colleagues (13.2%). The results of the logistic regression analysis revealed that high levels of resilience (OR = 1.28, p < 0.001), service motivation (OR = 1.17, p < 0.001), and non-exposure to death (OR = 0.33, p = 0.005) led to high work engagement. Mediation analysis showed that resilience and PSM mediated the influence of depression on work engagement. The work engagement of firefighters is influenced by resilience, PSM, and exposure to death.
