This article investigates longitudinal variations in grief, self-rated health, and symptoms of anxiety and depression among family caregivers in palliative care. Data were taken from a randomized psycho-educational intervention trial and were collected at four time-points; at baseline, upon completion, 2 months later, and 6 months after the patient's death. In total, 117 family caregivers completed all questionnaires. The participants' grief was stable across the measurements, while anxiety, depression, and health varied significantly (p < 0.05). No significant differences were found between the intervention or control group. In conclusion, grief emerged as a constant phenomenon, distinct from symptoms of anxiety and depression.
