Despite evidence of high psychological distress and unmet needs, evaluated interventions for informal caregivers in palliative care are few. This study involved an observational outcome evaluation of attendees, and a comparison group, in specialist home palliative care. The measures included carer psychological status and patient physical status at baseline, 8 weeks, and 20 weeks. Qualitative data were collected regarding content, satisfaction with, and impact of intervention. Process data described the uptake, resources, and group activity.
