Objective: To evaluate the efficacy of a practical, easily implemented, educational intervention in group format for informal carers of persons with dementia. Methods: Multi-centre, randomised, controlled, single-blind trial involving 292 family caregivers of patients with moderate dementia in Alzheimer's disease. Results: Participants valued program components which had a practical impact on their caring role. The intervention achieved minor effects on the participants' psychological quality of life and did not reduce carer depression.
