A qualitative study was conducted with semi-structured interviews to explore the experiences of suffering in 15 palliative care informal caregivers in University Malaya Medical Centre. The data were thematically analyzed. Seven basic themes were generated (1) empathic suffering, (2) anticipatory grief, (3) obsessive-compulsive suffering, (4) helpless-powerless suffering, (5) obligatory suffering, (6) impedimental suffering, and (7) repercussion suffering. A model of compassion suffering was conceptualized from the analysis. This model may serve as a guide in the assessment and management of suffering in palliative care informal caregivers.
