Objectives:
This study aimed to evaluate the psychometric properties of the Persian version of the International ICD-11 Prolonged Grief Disorder Scale (IPGDS).
Methods:
A total of 554 participants (18 years and older, 326 women) completed the Persian IPGDS along with other measures. Participants were recruited through convenience sampling. The study assessed confirmatory factor analysis (CFA), convergent validity, and reliability of the Persian IPGDS.
Results:
CFA supported a 4-dimensional model, indicating good structural validity of the Persian IPGDS. Convergent validity was established through correlations with measures of depression, anxiety, and PTSD.
Significance Of Results:
These findings suggest that the Persian IPGDS exhibits satisfactory psychometric properties, making it a valid tool for measuring Prolonged Grief Disorder (PGD) in Persian-speaking Iranian adults.
