The mediating role of regulatory emotional self-efficacy on negative emotions during the COVID-19 pandemic: A cross-sectional study.

Nurses exposed to coronavirus disease 2019 (COVID-19) are psychologically stressed. This study examines the characteristics and distribution of negative emotions among Chinese nurses during the COVID-19 pandemic and explores regulatory emotional self-efficacy (RESE) as the underlying mechanism in the relationship between nurses' personalities and negative emotions. A cross-sectional design with convenience sampling was utilized. Three comprehensive tertiary hospitals located in China were selected. Nurses (n = 339) who cared for COVID-19 patients were enrolled. Recruitment was conducted between 14 February 2020 and 1 March 2020. Self-reported questionnaires about personality, RESE, and epidemic-related negative emotions were completed online. A correlation analysis, structural equation modelling, and the bootstrapping method were used to analyse the data. This study identified a 24.9% incidence of negative emotions in nurses. RESE was a significant mediator explaining the effect of personality on epidemic-related negative emotions. RESE mediated the effect of introversion-extroversion on depression (β = -0.151, P = 0.015), neuroticism (β = -0.182, P = 0.007), fear (β = -0.142, P = 0.006), anxiety (β = -0.189, P = 0.015), and hypochondria (β = -0.118, P = 0.010); it also mediated the effect of neuroticism on depression (β = 0.313, P = 0.002), neuroticism (β = 0.394, P = 0.003), fear (β = 0.345, P = 0.005), anxiety (β = 0.384, P = 0.003), and hypochondria (β = 0.259, P = 0.004). Nurses caring for COVID-19 patients displayed negative emotions, particularly emotionally unstable and introverted nurses with a low RESE level. RESE is often essential for interventions because it significantly influences the relationship between personality and negative emotions. In the event of a major outbreak, tailored psychological well-being education, which includes emotional self-efficacy strategies, should be provided by organizations to help nurses manage stress related to the outbreak.
