After the necessary explanations and obtaining informed written consent, the questionnaires were completed by the clients. Finally, the data were analyzed using SPSS V.22 software and statistical tests. Values greater than 0.05 were also considered significant.Results: In this study, 29.2% were male and 68.8% were female, and corona-related anxiety was more common in women and married people.
