Rates of Prolonged Grief Disorder: Considering relationship to the person who died and cause of death

Background: Prolonged Grief Disorder (PGD) was recently included in DSM-5-TR. The rate of PGD is known to vary according to a number of factors and little is known about how bereaved individuals view the diagnosis. Methods: This cross-sectional study assessed PGD rates using the Prolonged Grief-13-Revised (PG-13-R) among a large sample (n = 1137) of bereaved individuals, considering the relationship to the deceased and cause of death. It also investigated bereaved individuals' attitudes toward the diagnosis. Results: Overall, 34.3 % of the sample met PGD criteria. Bereaved parents had the highest rate (41.6 %), followed by bereaved spouses/partners (33.7 %) and siblings (29.4 %). According to cause of death, those bereaved by substance overdose had the highest rate (59.1 %), followed by homicide/suicide (46 %) and accidental (36 %). The majority of respondents (65–95.6 %) viewed their responses, as measured by the PG-13-R items, as normal, and 98.1 % agreed that their responses in general were normal. Fewer than 12 % reported that a PGD diagnosis would be helpful to them. Limitations: This study used a self-selecting, non-representative sample that was predominantly female and white. Findings may or may not apply to more diverse groups and cannot be generalized. This study also used a self-report measure rather than a clinical interview. Conclusions: In line with prior research, this study found higher rates of PGD in specific subgroups, including bereaved parents, spouses, and those who lost loved ones to substance overdose, homicide/suicide, or accidents. Bereaved individuals in this sample generally did not view receiving a diagnosis of PGD as helpful.
