Peritraumatic distress, which is regarded as a predictor of post-traumatic stress disorder (PTSD), expresses the feeling of fear and helplessness experienced in the face of a traumatic event. It has been evaluated that the COVID-19 pandemic can lead to peritraumatic reactions and PTSD symptoms. The study aimed to adapt the "COVID -19 Peritraumatic Distress Index (CPDI)", which was developed to determine peritraumatic distress levels during the COVID-19 pandemic, to Turkish culture. The study was conducted with 248 participants. The CPDI scale items were translated into the Turkish language. Confirmatory factor analysis (CFA) was performed to determine the construct validity of the scale. And the Cronbach alpha (a) reliability coefficient was calculated for reliability. As a result of the analyses, the original structure of the scale was confirmed and construct validity was ensured. This measurement tool can be used to assess the peritraumatic distress levels of the Turkish population.
