Introduction: This study aimed to examine the psychometric properties of the Persian version of the Traumatic Grief Inventory–Self Report (TGI-SR) in a convenience sample of Iranian bereaved individuals.
Methods: The present survey research; included 138 bereaved adults (127 women and 11 men; mean age = 44 years); who had experienced the death of a loved one more than one year prior and were recruited via convenience sampling. Participants completed the Persian TGI-SR along with the Brief Symptom Inventory (BSI-53) and the Oxford Happiness Inventory (OHI). Data were analyzed using CFA, correlation coefficients and reliability indices including Cronbach’s alpha, McDonald’s omega, and composite reliability.
Findings: After model modifications, CFA indicated acceptable model fit; all items except item 15 had factor loadings above 0.40. The AVE was 0.41. Internal consistency was satisfactory, with Cronbach’s alpha = 0.92, McDonald’s omega = 0.91, and CR= 0.90. Correlations with BSI-53 (r = 0.76, p < 0.001) and OHI (r = -0.54, p < 0.001) confirmed convergent and discriminant validity.
Conclusion: The Persian TGI-SR demonstrates adequate reliability and validity; however, revision of item 15 and use of a more diverse sample are recommended to enhance generalizability.
