Korean Version of the Prolonged Grief Disorder Scale (PG-13-K): A Validation Study

Abstract

This study aims to examine the validity and reliability of the Korean version of the Prolonged Grief Disorder Scale (PG-13-K). For this study, an online survey was conducted with 706 Korean adults who have lost a loved one. Results were as follows: First, principal factor analysis identified a two-factor structure: ‘Traumatic distress’ and ‘Separation distress’ accounted for 66.45% of the total variance. Second, high internal consistencies were found for PG-13-K. Third, confirmatory factor analysis supported the two factors structure of the PG-13-K. Fourth, the PG-13-K had positive correlations with both the IES-R-K (PTSD) and BSI-18 (depression, anxiety). The mean score of the PG-13-K was significantly higher in participants experiencing grief due to traumatic death vs. natural death. Overall, the PG-13-K is a valid measurement tool for prolonged grief within the Korean population. Implications and limitations are discussed.
