Psychometric Properties of the Korean Version of the Revised Prolonged Grief Disorder Scale for Bereaved Adults.

This study aims to validate the Korean version of the Revised Prolonged Grief Disorder scale (PG-13-R-K) by exploring the psychometric properties of the revised Prolonged Grief Disorder scale in bereaved South Korean adults. A total of 694 bereaved individuals who had experienced the loss of a close person for a duration ranging from 12 to 24 months were included in this study and randomly divided into two separate datasets to conduct factor analyses. The results of both EFA and CFA revealed a single-factor structure for the PG-13-R-K. Moreover, the results of reliability and validity tests showed adequate internal consistency and concurrent validity. These findings suggest that the PG-13-R-K is a reliable and valid tool for assessing PGD symptoms among bereaved Korean adults. The limitations and implications of this study are thoroughly examined and discussed.
