Reliability and Validity Study of the Turkish Version ofthe COVID-19 Peritraumatic Distress Index

Abstract

Objective: The Coronavirus Disease 2019 (COVID-19) pandemic, affecting people world wide, negatively affects the mental health of people. During this situation, accurate andreliable tools are needed to evaluate mental state. The aim of this study was to translatethe COVID-19 Peritraumatic Distress Index (CPDI) into Turkish, and analyze it for validityand reliability. Methods: The original form of the CPDI was translated into Turkish using the back transla tion method. It was then applied to over 400 individuals, randomly selected from patientsand their relatives, between the ages of 18 and 70, who presented to the outpatient clinicsof Mustafa Kemal University Research Hospital. Data were collected with a demographicdata form. Exploratory and confirmatory factor analyses were done. Construct validity,item content validity index, and content validity were analyzed. Cronbach’s alpha vs.Spearman-Brown reliability analyses were done. Results: Cronbach’s alpha coefficient for the CPDI was found to be 0.842, which is quite high.Cronbach’s alpha coefficient for the subscales ranged from 0.670 to 0.780. The Spearman Brown reliability coefficient was 0.730. The confirmatory factor analysis revealed goodfit indices (χ2 /df=1.94; root mean square error of approximation=0.05; Comparative FitIndex=0.93; Adjusted Goodness of Fit Index and Tucker-Lewis Index=0.91). The meantotal score was 27.26 (SD=12.28), while the mean subscale scores ranged from 4.83 to10.26. Conclusion: The Turkish version of the CPDI is valid and reliable, and can be used in stud ies evaluating the COVID-19 peritraumatic stress.
