The objectives of this study are to explore the feasibility of a multicomponent intervention programme and to evaluate its impacts on behavioural and psychological symptoms of dementia (BPSD) and psychological health of caregivers.
Fifty-six community-dwelling people with dementia (PWD) and knee osteoarthritis (OA) and their caregivers were recruited and randomized into the intervention group (IG) or comparison group (CG). Each participant in both groups received an individual physiotherapy session (personalized home exercises and care education) and underwent 8 weeks of a 1-hour-structured group exercise session weekly at a day care centre. They were instructed to follow the prescribed home exercise. The IG received a multicomponent programme, combining knee OA-specific therapeutic exercise with self-management support, while the CG attended the routine group exercise programme. The attendance rate and reasons for non-attendance were recorded for evaluating the feasibility. The Chinese versions of the Revised Scale for Caregiving Self-Efficacy (RSCSE) and the Neuropsychiatric Inventory Questionnaire (NPI-Q) were measured at the baseline and postintervention.
Fifty-four dyads completed the programme with high attendance rate (94.4%). Compared with the CG, caregivers in the IG significantly improved in three domains of RSCSE scores (P ≤ .005) and caregivers' distress (P = .004) after the intervention. However, no effects were observed in terms of BPSD severity in PWD. No adverse events or falls were reported.
This multicomponent programme is feasible and safe for dementia caregivers and older people with mild-to-moderate dementia and knee OA. The programme has beneficial effects on caregiving self-efficacy and distress of dementia caregivers.
