ABSTRACT
Purpose: The aim of this study is to examine the levels of intolerance of uncertainty, rumination and resilience among healthcare workers during the COVID-19 pandemic. Materials and Methods: This descriptive and cross-sectional study was conducted with 310 healthcare workers. Data were collected using an Introductory Information Form, the Intolerance of Uncertainty Scale, the Ruminative Thought Style Questionnaire and the Brief Resilience Scale. Results: In this study, it was found that ruminative thinking style was lower in healthcare workers aged 37 years and over and with more experience, and higher in shift workers. As a result of multiple linear regression analysis, it was determined that intolerance to uncertainty and psychological resilience have a significant effect on ruminative thinking style. Intolerance of uncertainty and resilience explained 38.5% of the total variance in rumination, and both variables were identified as significant predictors of rumination. Conclusion: The levels of intolerance of uncertainty and rumination among healthcare workers can be reduced by closely monitoring the working conditions and mental states of the workers and developing programs to protect the workers from potential negative psychological effects and to improve their resilience.
