Based on coping theory, the current research examines how and why COVID-19 phobia affects frontline healthcare professionals’ mental health, as well as their burnout and work-related stress. We focused on the mediating role of burnout and work-related stress in this study. In the current study, we also examined the moderating influence of healthcare professionals’ handwashing behavior using the Hayes Process model. We employed a daily diary approach to collect data from respondents in Pakistan’s frontline healthcare professionals (n = 79, 79 × 10 = 790) who were directly treating COVID-19 patients during the omicron wave. According to the findings of the study, COVID-19 phobia significantly disturbs healthcare professionals’ mental health, as well as significantly strengthens burnout and work-related stress. The findings also demonstrated that burnout significantly negatively influences mental health. The mediation influence of burnout and work-related stress in the association between COVID-19 phobia and mental health has shown to be significant. The moderation analysis revealed that high handwashing behavior significantly buffers the negative impact of COVID-19 phobia, as well as the adverse effect of burnout on healthcare professionals’ mental health. Moreover, our findings have theoretical and managerial implications, as well as new research directions for scholars to understand the adverse impact of daily obstacles on professionals’ (nurses and doctors, etc.) mental health and work performance, as well as issues based on resource conversation philosophy.

The current study investigates the impact of fear related to coronavirus 2019 (COVID-19) disease on situational humor, and also on social networking sites (SNS) usage as a mediator. Furthermore, this study investigates the impact of fear-related COVID-19 disease on situation humor via SNS usage, focusing on the gender perspective of university students. This study also examined the impact of fear related to COVID-19 disease on situational humor in students from various degree programs, such as BS and MS. For this cross-sectional study, data were collected from 24 different Pakistani universities using purposive sampling between December 2020 and May 2021. This study used social media platforms like WhatsApp, Facebook, LinkedIn, and Twitter (and also email) to collect data online. According to the findings of this study, fear related to COVID-19 disease was found to be significantly negatively related to situational humor and SNS usage, whereas SNS usage was positively related to situational humor. The findings also revealed that SNS usage is a key mediator in the relationship between fear related to COVID-19 disease and situational humor. In addition, male university students used more SNS and had a higher situational humor response than female university students, and female university students reported a higher fear related to COVID-19 disease. This study provided useful findings of the impact of fear related to COVID-19 disease on situational humor among students in various academic programs, such as bachelor's program and master's program.
