Group multi-component programme based on cognitive behavioural therapy and positive psychology for family caregivers...

Caregivers of people with dementia frequently experience an elevated level of psychological distress and burden. This study aimed to examine the effectiveness of a group-format multi-component programme which is based on cognitive behavioural therapy and positive psychology.

Family caregivers of dementia were allocated (1:1) to the intervention group and the wait-list control group, stratified by age (<65 years, ≥65 years) and care status (at home or in an institution). The intervention group received a six-session, 10-week, group-format programme. The primary outcome was the Hospital Anxiety Depression Scale (HADS). Secondary outcomes were the short-version of the Zarit Burden Interview (personal strain and role strain), Neuropsychiatric Inventory Questionnaire, Dementia Caregiver Positive Feeling Scale, and Self-Compassionate Reactions Inventory. The evaluations were conducted at baseline, 10 weeks (post-intervention), and 14 weeks (follow-up).

The analyses were performed with 64 registered participants. In the whole sample, no significant effect was observed on HADS. There was medium effect on role strain (P = 0.04, partial η²  = 0.08). Positive feelings of caregiving increased after the intervention but were not maintained at follow-up. In the subgroup analysis of caregivers under 65 years of age, a statistically significant effect was observed for personal strain (P = 0.03, partial η² = 0.16). An interaction effect was also found for the total score of positive feelings of caregiving (P < 0.05, partial η² = 0.02) and the meaning of caregiving (P = 0.02, partial η² = 0.10).

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.
