OBJECTIVE: Depression and prolonged grief disorder (PGD) are related but distinct constructs with different risk factors and treatments. We aimed to determine commonality and differences in factors predicting membership in depressive- and PGD-symptom trajectories to highlight uniqueness of each construct to guide further care and treatments. METHODS: We previously identified four shared trajectories for depressive- and PGD-symptom trajectories (endurance, transient-reaction, resilience, and prolonged-symptomatic) with unique trajectories of chronically distressed and potential recurrence for depressive and PGD symptoms, respectively. This secondary-analysis study examined pre- and postloss factors predisposing 849 bereaved caregivers of cancer patients to membership in depressive- and PGD-symptom trajectories from the integrative framework of predictors for bereavement outcomes by a multinomial logistic regression model (the "endurance" trajectory as reference). RESULTS: Common factors predicted membership in depressive- and PGD-symptom trajectories: higher postloss personal coping capacity protected from more distressing symptom trajectories, spousal relationship with the patient predicted membership in the transient-reaction trajectory, while financial hardship and preloss depressive symptoms predicted for the resilience trajectory. Yet, accurate prognostic awareness protected caregivers from more distressing depressive-symptom trajectories only. Higher preloss subjective caregiving burden protected caregivers from the four more distressing depressive-symptom trajectories but only from the transient-reaction and resilience trajectories for PGD symptoms. CONCLUSION: Commonality and differences in factors predicting membership in PGD- and depressive-symptom trajectories confirm that PGD and depression are related but distinct constructs. Interventions should be tailored to caregivers' unique risk profile for depressive- and PGD-symptom trajectories to reduce the likelihood of suffering both or individual symptom trajectories.
