Psychometric properties of the Persian version of the pandemic grief scale

This study evaluated the psychometric properties of a Persian version of the pandemic grief scale (PGS) using a sample of 473 people who had experienced the death of a loved one to coronavirus (Covid-19). The results of this study demonstrated that this version of the PGS has internal consistency reliability (omega coefficient of 0.86) and test-retest reliability with an interval of three weeks (intraclass correlation coefficient of 0.89) scores in the highly reliable ranges. Confirmatory factor analysis results of a uni-dimensional model support the construct validity of this version of the PGS, while convergent and divergent validity was shown with significant correlations between the PGS and measures of depression, anxiety, functional impairment, and hope. Overall, the Persian version of the PGS showed good psychometric properties in the Iranian population.
