A caregiver support group was initiated at the Schizophrenia Research Foundation, Chennai, India. The study aimed to evaluate this service for 100 caregivers of persons with dementia, identify the needs met and explore the facilitating factors and barriers for participation. The support group met the information, emotional and counselling needs of caregivers. Trust between members was a key facilitating factor. Lack of help at home to support the person with dementia, distance from the venue and work commitments were barriers to caregiver participation. The study found that support groups fulfil an important need for caregivers by providing information and peer support.
