Objectives: To examine similarities and dissimilarities in patient and family caregiver dyads in their experience of stress, support, and sense of security. Methods: 144 patients and their family caregivers participated. Patients were admitted to six Swedish specialist palliative home care units and diagnosed with a non-curable disease with an expected short survival. We analysed similarity patterns of answers within dyads (correlations) as well as dissimilarities, expressed as the difference between within-dyad responses.
