Prevalence of prolonged grief disorder.

BACKGROUND

Prolonged grief is a disorder (PGD) characterized by severe and disabling grief reactions for an extended period of time after the loss of a significant person. ICD-11 and DSM-5-TR differ substantially in individual criteria.

OBJECTIVE

Estimation of the respective prevalence of PGD and PGD and the frequency with which single symptoms of prolonged grief occur in the general population.

METHODS

Out of a representative sample of the German general population (N=2498), n = 914 reported a significant loss and prolonged grief symptoms based on the extended version of the self-reported Prolonged Grief Disorder-13+9 (PG13+9). Sociodemographic and loss-related characteristics were collected.

RESULTS

The probable prevalence of PGD was 1.5% and that of PGD was 1.2% in the general sample. Among bereaved persons (n=914), the prevalence of developing PGD was 4.2% and that of PGD was 3.3%. Diagnostic agreement between the two criteria-sets was very high and did not increase after heightening the accessory symptom threshold for PGD. Difficulties accepting the loss was the most frequent single symptom (14-25%) and grief-related impairment was common (10-16%). Over 60% of participants with a probable PGD diagnosis utilized health care services.

LIMITATIONS

Results are based on self-reported data. The PG13+9 was not designed to assess grief symptoms according to ICD-11 and DSM-5-TR diagnostic criteria.

CONCLUSIONS

Prolonged grief according to ICD-11 and DSM-5-TR is a notable disorder in the general population. Among bereaved persons, single symptoms of prolonged grief are relatively frequent and cause substantial degrees of impairment.
