description

Individuals suffering from prolonged grief disorder (PGD) show severe grief reactions after the death of a significant other, even beyond a period of grieving that is within a person's cultural and religious context. In addition to this core element, PGD can manifest in various ways. Symptoms may include persistent preoccupation, intense emotional pain, or impairment in important life domains. The symptoms, furthermore, have to be of culturally or religiously inappropriate extent or severity, taking into account different norms of grieving. PGD is discussed as a distinct diagnostic category in the revision of the International Classification of Diseases (ICD-11). Nosology of PGD has been highly debated surrounding the suggested inclusion in the DSM-5, which had been declined due to insufficient evidence. This paper addresses the latent nature of PGD. Using a short form of the Inventory of Complicated Grief-Revised (ICG-R), we applied three popular taxometric methods: MAXEIG, MAMBAC and L-Mode. Data stemmed from a subsample of N = 1445 bereaved individuals that participated in a large representative German population survey (N = 2520). The analysis strongly indicated a dimensional latent structure of PGD. Implications of the conceptualization of PGD on a continuum are discussed, regarding measurement, diagnosis, etiology and future research.
