Associations Between Anticipatory Grief and Post-Bereavement Depression and Post-Loss Grief of Family Members of Dying Patients With Cancer in Palliative Care Units: A Cohort Study

Abstract

Objectives: Anticipatory grief is associated with post-bereavement grief; however, reports on the influence of pre-loss depression are limited. Therefore, we investigated the association between the anticipatory grief of family members and post-loss and post-depression grief adjusted for pre-loss depression. Methods: This cohort study included the family members of dying patients with cancer. Questionnaires were distributed to them during hospitalization in four inpatient palliative care units from 2016 to 2017. We also administered follow-up questionnaires after their bereavement in 2018. The pre-bereavement questionnaire consisted of three items from the Anticipatory Grief Scale for Families Caring for a Terminally Ill Person for assessing anticipated grief and the Patient Health Questionnaire 9 for assessing depression. The Brief Grief Questionnaire was used to assess post-loss grief. Results: We distributed 181 pre-bereavement questionnaires to the family members; 112 (62%) responded to the pre-bereavement survey, out of which 71 (63%) responded to the post-bereavement survey. Anticipatory grief was significantly associated with pre-loss (ρ = 0.37, ρ < 0.001) and post-loss (ρ = 0.24, P = 0.009) depression and marginally associated with post-loss grief (ρ = 0.15, P = 0.10). Pre-loss depression was also significantly associated with post-loss depression (ρ = 0.50, P < 0.001) and post-loss grief (ρ = 0.41, P < 0.001). However, anticipatory grief was not significantly associated with post-loss depression (P = 0.35) and post-loss grief (P = 0.65) after adjusting for pre-loss depression. Significance of Results: Bereaved families who experienced anticipatory grief had worse post-bereavement depression. However, this association was not statistically significant after adjusting for pre-bereavement depression. Post-bereavement depression may be in a continuum with pre-loss depression, and anticipatory grief does not independently affect post-loss reactions.
