Family caregiver grief and post-loss adjustment: A longitudinal cohort study

In order to better understand the different grieving trajectories of the family caregivers (FCs), this study aims to examine the evolution of prolonged grief disorder (PGD) symptoms and the predictive role of the caregiving-related factors in the FCs' grieving trajectory from pre- to post-death.

A prospective cohort study was carried out with advanced cancer FCs evaluated before death (T1) and 6-12 months post-loss (T2).

Participants in T1 (n = 156) were mostly female, adult child, or spouse of the care recipient, with a mean age of 51.78 (SD = 13.29). At T2, 87 FCs participated in the survey. PGD prevalence was higher pre-death (38.6%) than in bereavement (33.7%). Of those who met the PGD criteria before death, most also met these criteria after death (n = 26, 61.9%). Psychological distress and caregiver burden were highly correlated with pre-death grief, which in turn played a critical role in mediating the link between psychological distress and bereavement outcome. Great emotional closeness in the relationship was predictive of PGD symptoms persistence. In contrast, the long-term consequences of caregiver burden were not confirmed.

This study provides evidence for the diversity of individual FC responses and the complex pattern of interactions between caregiving-related factors, relationship quality, and PGD symptoms evolution from pre- to post-death.
