  The epidemic of a disease called COVID-۱۹ in the world caused the treatment staff in all hospitals to gain new experience. A painful and combined experience of rapid spread and lack of awareness about this disease. Working around the clock and facing high mortality caused psychological pressure on the treatment staff. At the forefront of them were the nurses, whose research revealed that high work pressure and caring for a patient with Covid-۱۹ caused them to suffer from a mental disorder called post-traumatic stress disorder. The purpose of this study was to investigate the effectiveness of cognitive behavioral therapy on reducing the symptoms of post-traumatic stress disorder in the nursing staff involved in the care of patients with COVID-۱۹ in Tehran hospitals. The research design is semi-experimental and pre-test and post-test design with a control group. The sample people were selected by available sampling method and were randomly divided into two experimental and control groups. The subjects of the experimental group were assessed using the post-traumatic stress disorder list (PCL-۵) before the intervention and after. It was done virtually. The comparison of the experimental and control groups was done by controlling the effect of the pre-test with the analysis of covariance (ANCOVA) method. The results of calculations showed that cognitive behavioral therapy is generally effective in reducing the symptoms of post-traumatic stress disorder in nursing staff involved in the care of Covid-۱۹ patients. Therefore, it can be said that cognitive behavioral therapy has been able to partially reduce the symptoms associated with negative changes in cognition and the creation of PTSD disorder in nurses involved with covid-۱۹ patients. However, there was no significant difference in the average post-test scores of the subscale of "interference" of the experimental group and the control group (P>۰.۰۵). As a result, cognitive-behavioral therapy is not effective in reducing the disturbing and repetitive symptoms of PTSD.
