Abstract

Abstract : Introduction: Despite increasing numbers of persons living with Alzheimer's disease and Alzheimer's-related dementias (AD/ADRD) in Asia, particularly in low-income countries (LIC) and middle-income countries (MIC), surprisingly little is known about the current state of the evidence for family caregiver interventions. The objectives of this scoping review were to: (1) describe the evidence for efficacy of family dementia-caregiver psychosocial interventions in Asian countries, (2) compare evidence across LIC, MIC, and high-income countries (HIC), and (3) characterise cultural adaptions to interventions developed outside Asia. Methods: The inclusion criteria included: (1) conducted in Asia (2) included an intervention delivered to a family caregiver of a person living with AD/ADRD, (3) reported quantitative outcomes for the family caregiver and (4) published in a peer-reviewed journal with full text available in English. Results: Thirty intervention trials were identified meeting inclusion criteria and all reported statistically significant (p<0.05) improvement in one or more caregiver outcomes. Interventions usually included multiple components. The most frequently reported outcomes (ie, by ≥20% of studies) were caregiver depression, burden, quality of life and self-efficacy. Overall, 26 (87%) of the studies were conducted in HIC in Asia, primarily in Hong Kong SAR—China and Taiwan, and only 4 (13%) in LIC and MIC in Asia. Seven studies (23%) used interventions developed in USA and several described cultural adaptations. Conclusion: This scoping review found substantial evidence, particularly from high-income Asian countries, that a wide range of interventions improve AD/ADRD family caregiver outcomes. However, critical knowledge gaps exist, particularly for LIC and MIC in Asia, where the number of persons with dementia is numerically largest and projected to increase dramatically in coming decades. The field could also benefit from more detailed descriptions of the process and types of cultural adaptations to interventions.
