Predictors of poor psychological functioning of healthcare workers based in Greece during the COVID-19 pandemic.

Background: Poor psychological functioning during the COVID-19 pandemic has been reported in several studies of healthcare workers from around the world. Factors that might predict this have yet to be established.

Objectives: First, to ascertain which factors were associated with poor psychological functioning in a cohort of healthcare workers during the COVID-19 pandemic. Second, to characterize key sociodemographic aspects of this cohort. Third, to determine the degree to which any predictors of poor psychological functioning were associated with each other.

Methods: A questionnaire-based cross-sectional study was conducted of 144 healthcare workers in Patras, Greece, during the COVID-19 pandemic. The questionnaire consisted of: (1) demographic survey questions; (2) the Psychological Consequences Questionnaire scale; (3) the Kessler Psychological Distress scale; and (4) Toulouse's scale for coping strategies. The data were analyzed using general linear modeling.

Results: The statistical model (p < 10^-10) indicated that smoking or taking drugs to calm anxiety, feeling ashamed, and being overwhelmed by one's feelings were all predictors of poor psychological functioning. Conversely, income was a protective factor. A post hoc network analysis showed that smoking or taking drugs to calm anxiety was relatively strongly associated with feeling ashamed; the latter was also associated with feeling overwhelmed. There was a weak negative association between income and feeling ashamed.

Conclusion: This study highlights the critical importance of psychological functioning in shaping the mental well-being of healthcare professionals during pandemics. Prioritizing the mental health of frontline workers is crucial for their well-being and for the overall functioning of healthcare systems.
