Abstract: Background and Objectives: Many community dementia services such as home-visiting services and center-based activities were suspended during the coronavirus 2019 pandemic. This study investigated the efficacy of a caregiver-delivered cognitive stimulation therapy (CDCST) on people with dementia during the pandemic.
Research Design and Methods: This was a 2-arm randomized controlled trial involving 241 patient–caregiver dyads assigned to a 15-week CDCST or control group (usual care). We hypothesized that CDCST would facilitate significant improvements among people with dementia (cognition, behavioral/psychiatric symptoms, and quality of life) and their caregivers (caregiving appraisal, attitudes, and psychological well-being) at postintervention (T1) and at the 12-week follow-up (T2). Generalized estimating equations evaluated the study outcomes.
Results: A total of 230 dyads completed the study, with good program adherence (93%). Participants in the CDCST showed significant improvements in cognition (p < .001), behavioral and psychiatric symptoms (p =. 027), and quality of life (p =.001) at the 3-month follow-up period. Family caregivers had improved positive aspects of caregiving (p = .008; p = .049) and decreased negative attitudes toward people with dementia (p =. 013; p < .001) at both T1 and T2. There were nonsignificant changes in the caregivers’ perceived burden, distress, and psychological well-being.
Discussion and Implications: Family caregivers could be trained to provide cognitive stimulation at home for people with dementia, which could benefit both parties. CDCST could manage to improve the cognition, neuropsychiatric symptoms, and quality of life of people with dementia, while also improving caregiving appraisal and negative attitudes among family caregivers.
