This study aimed to evaluate the integrated cognitive-behavioral group therapy and Gestalt empty chair technique on bereaved individuals with COVID-19-caused PGD (prolonged grief disease). Thirty-six patients with PGD resultant from COVID-19 were randomly assigned intervention and control groups. The intervention group underwent 16 90-minute integrated group therapy sessions twice a week. Both groups completed the BDI II depression, NAI anger, and GASP guilt scale before, after, and 2 months after the study’s conclusion. The intervention and control groups significantly differed in the depression, anger, and guilt indices after the therapeutic intervention ( p < .001). This difference remained in the follow-up phase. Integrated group therapy in treating could help with some of the symptoms of PGD resulting from the corona-caused loss of loved ones. This reduction in symptoms was also stable over time.
