Differential correlates of prolonged grief and depression after bereavement in a population-based sample

Bereavement can lead to prolonged grief disorder (PGD) as well as episodes of major depression. Studies on the prevalence of PGD and its differences from postbereavement depression have not been conclusive. This study compared the correlates of depression and prolonged grief (PG) symptoms in a population-based random sample (N = 535) using the Beck Depression Inventory, Inventory of Complicated Grief-Revised, Anxiety Sensitivity Index (ASI), and Adult Separation Anxiety Questionnaire (ASAQ). Correlates of PG and depressive symptoms were examined using linear regression in 328 bereaved respondents. The prevalence of probable PGD based on PGD-2009 criteria was 3.0% among bereaved respondents and 1.9% in the total sample. PG was related to bereavement-related features including sex of the deceased, β = - .110, p = .026; time since loss, β = - .179, p = .001; the number of lifetime losses experienced, β = .157, p = .016; and perceived closeness with the deceased, β = .214, p < .001. Only lower income of the bereaved predicted depression, β = - .139, p = .018. In women, but not in men, the loss of a male family member (i.e., brother or son) was a significant predictor of PG symptoms, β = - .180, p = .006. The results confirm the qualitative distinction between depression and PG in a nonclinical sample and show that PG is mainly related to the intrinsic and extrinsic characteristics of the deceased or of death, whereas depression relates only to the characteristics of the bereaved person.
