Psychometric Properties of the TGI-SR in a Sample of Bereaved Individuals from Bali

Abstract

Persistent complex bereavement disorder (PCBD) and prolonged grief disorder (PGD) are diagnostic entities describing disturbed grief following the loss of a loved one. The psychometric properties of measurements for the PCBD and the PGD have been evaluated in the Western culture, but not in the Hindu culture. This paper investigated the psychometric properties of the TGI-SR in a sample of 301 participants from Bali who lost a family member in a car accident. The TGI-SR is an 18-item grief self-measure scale combining the symptoms of PCBD and PGD. The factor analysis extracted three factors for all 17 PCBD items and three factors for the 11 PGD items. Our results indicate that the TGI-SR is a reliable and valid measurement and support the usability in Bali.
