Cultural Adaptation of the Reducing Disability in Alzheimer's Disease (RDAD) Protocol for an Intervention to Reduce Behavioral and Psychological Symptoms of Dementia in Thailand.

BACKGROUND: The Reducing Disability in Alzheimer's Disease (RDAD) program is an evidence-based intervention found to be feasible for implementation in community settings in the United States, and effective in reducing depression, one of the major behavioral and psychological symptoms of dementia (BPSD). OBJECTIVE: The goal of the study is to culturally adapt the RDAD for persons with dementia living in community settings of Thailand. METHODS: Key adaptation steps included: 1) assess the community, 2) understand/select the intervention, 3) consult with experts/stakeholders, 4) decide what needs to be adapted, 5) adapt the original program, 6) train staff, and 7) pilot test the adapted materials. RESULTS: Modifications to the original RDAD protocol included changes in number of sessions, mode of delivery, and the specific pleasant activities targeted. The pilot test demonstrated the feasibility and acceptance of the adapted RDAD intervention protocol. Implementers were able to comprehend and implement the core components of the intervention, while family members demonstrated ability to follow instructions, gain knowledge about dementia, and improve skills for setting up realistic goals. CONCLUSION: Following the key adaptation steps outlined above, we were able to successfully modify the RDAD for the Thai cultural context, maintaining core components of the original protocol. Program implementers demonstrated their ability to supervise family caregivers and help them gain the knowledge and skills needed to provide care for older adults with dementia. Findings from the pilot studies were incorporated into final training and intervention protocols currently being implemented and evaluated in a randomized implementation trial in Thailand.

Implementation Science in Thailand: Design and Methods of a Geriatric Mental Health Cluster-Randomized Trial.

BACKGROUND: Thailand has a rapidly aging population yet lacks evidence for effective and scalable evidence-based psychosocial interventions to support persons living with dementia and their family caregivers. In this study of a culturally adapted and evidence-based clinical program (Reducing Disabilities in Alzheimer's Disease [RDAD]), designed to reduce behavioral and psychological symptoms of dementia in older adults, the authors test the hypothesis that an implementation support strategy, Getting To Outcomes (GTO), would produce better implementation and clinical outcomes compared with usual implementation of RDAD in Thailand. METHODS: The study uses a hybrid type III cluster-randomized design to compare eight geographical districts that receive training on both implementing the RDAD clinical intervention and on GTO implementation support strategies (intervention arm) with eight other districts that receive the same RDAD training but without training in GTO implementation support strategies (control arm). GTO is an evidence-based intervention designed to support implementers to better plan, implement, and evaluate innovative intervention programs in a novel setting. Primary outcomes, including implementation and clinical outcomes, will be assessed at baseline, month 3 (posttreatment), and month 6 (3-month follow-up). RESULTS: The research team anticipates that there will be significantly more improvements in the delivery of the RDAD intervention program in the experimental group than in the control group. NEXT STEPS: If clinical trial findings are positive, the authors plan to replicate and scale up the proposed implementation science approach across Thailand to enhance and expand mental health services for older adults with dementia.
