The objective of this study was to adapt the COVID-19-Impact on Quality of Life (COV19-QoL) scale for Turkish individuals and to determine its validity and reliability.

Materials and Methods. This methodological study was conducted between December 25, 2020 and January 10, 2021. The research was conducted online and included 485 participants who completed a socio-demographic questionnaire, the COV19-QoL scale and the Duke Health Profile (DUKE) on Google Forms. Back translation was used for the Turkish version of the COV19-QoL scale. Language and content validity of the scale were found to be acceptable.

Results. Ten experts were consulted regarding content validity of the scale. The results, item content validity of 0.95 and scale content validity of 0.95, indicated excellent content validity. Explanatory factor analysis found one principal structure with a total variance of 59.449%. The Cronbach’s alpha internal consistency coefficient was 0.86 for the scale. A statistically significant moderate negative correlation was found between the participants’ COV19-QoL scale score and their general health score on the DUKE (r = − 0.384; p < 0.01).

Conclusions. This study found that the Turkish version of the COV19-QoL scale is a valid and reliable instrument for assessing the effects of the COVID-19 pandemic on the Turkish population’s quality of life.
