The world is currently experiencing a pandemic of an infectious disease called COVID-19 which has drawn global intensive attention. While global attention is largely focusing on the effects of the coronavirus on physical health, the impacts of the coronavirus on psychological health cannot be overlooked. Therefore, this study aims to adapt the Fear of COVID-19 Scale into Turkish and investigate the relationships between fear of COVID-19, psychological distress, and life satisfaction. Data were collected by convenience sampling method, which allowed us to reach total 1304 participants, aged between 18 and 64 years, from 75 cities in Turkey. In the adaptation process of the Fear of COVID-19 Scale, confirmatory factor analysis, Item Response Theory, convergent validity, and reliability (Cronbach's alpha, McDonald's omega, Guttmann's lambda 6, and composite reliability) analyses were performed. Additionally, the mediating role of psychological distress on the relationship between fear of COVID-19 and life satisfaction was tested. The uni-dimensionality of the 7-item scale was confirmed on a Turkish sample. Item Response Theory revealed that all items were coherent and fit with the model. The results indicated that the Turkish version of the scale had satisfactory reliability coefficients. The fear of COVID-19 was found to be associated with psychological distress and life satisfaction. Results indicated that the Turkish version of the Fear of COVID-19 Scale had strong psychometric properties. This scale will allow mental health professionals to do research on the psychological impacts of COVID-19 in Turkey.
