symptom trajectories

Background: Family caregivers' distinct depressive-symptom trajectories are understudied and have been examined independently during end-of-life (EOL) caregiving or bereavement, making it difficult to validate two competing hypotheses (wear-and-tear vs. relief) of caregiving effects on bereavement. Existing studies may also miss short-term heterogeneity in depressive symptoms during the immediate postloss period due to lengthy delays in the first postloss assessment.

Objective: Grief reactions in bereaved caregivers of cancer patients have been identified individually as distinct prolonged grief disorder (PGD)—and major depressive disorder (MDD)—symptom trajectories, but no research has examined whether the patterns of change (trajectories) for PGD and MDD symptoms synchronize during bereavement.
