Group multi-component programme based on cognitive behavioural therapy and positive psychology for family caregivers of people with dementia: a randomised controlled study (3C study).

This programme did not show significant improvement in depression and anxiety of caregivers of dementia; however, it reduced the burden of their role conflict (role strain) and yielded favourable short-term effects on the positive feelings and the meaning of caregiving among the participants. Also, the programme effectively reduced the personal strain of caregivers under 65 years.
