Explaining how and why social support groups in hospice day services benefit palliative care patients, for whom, and in what circumstances.

Hospice day services facilitate group settings for reciprocal social support. This research proposes an initial programme theory that can be further developed and tested. It explains how and why, in some contexts, social support increases personal and practical resources to cope with illness and death, leading to changes outside of the hospice (to mood, interpersonal interactions and behaviour) that could improve quality of life.
