Twenty-four (24) caregivers, the identified secondary caregiver, and a care recipient will be randomly assigned into the active intervention or a control condition: 16 triads in the intervention condition, 8 in the control.
For the primary caregivers: Primary caregivers will attend six weekly intervention sessions lasting 2 hours each. Based on previous Randomized Controlled Trials (RCTs) of a successful behavior change (i.e., smoking cessation) intervention in Vietnamese using only 2-3 sessions, six sessions were chosen as a middle ground. In the first 45 minutes, primary caregivers and a secondary caregiver (who the primary caregiver identifies) will participate in family psycho-education delivered by a Master's level trained, bilingual facilitator. Each group will consist of no more than four dyads (4 different groups totaling 16 dyads). The curriculum will be adapted based on what the Alzheimer's Association and REACH II have successfully used as well as what the University of California (UC) Davis Alzheimer's Disease Center (ADC) has implemented. The sessions will cover the following: a clinical model of dementia and helping family members come to a shared understanding of the nature and cause of dementia. The innovative component is a discussion of cultural values typical of individuals in Vietnamese and American cultures and how this can influence perceptions of dementia and caregiving strategies. This is important because it will help family members who disagree on the etiology of dementia and strategies for care to empathize with each other's perspective. Subsequent sessions will help caregivers learn skills and develop self-efficacy in dealing with patient symptoms, accessing resources (e.g., in-home support), and gaining family support in culturally-congruent ways. Facilitating the use of formal and informal support is a critical piece as Vietnamese caregivers may be looking for basic and concrete assistance rather than help in coping with caregiving.
The last part of the intervention is mindful Tai Chi that was chosen for several reasons. In a recent review and meta-analysis, Tai Chi showed beneficial effects on depression, anxiety, stress management, and self-efficacy. Second, Tai Chi is rooted in East Asian traditions and philosophies that promote balance and healing of the mind and body, thus addressing holistic beliefs Vietnamese have about wellness. An RCT of Tai Chi recently was successfully completed in Vietnam, demonstrating its growing acceptance in the Vietnamese population. The protocol will be adapted to meet caregivers' needs and highlight meditation that involves accepting stressful circumstances, thus capitalizing on emotion regulation strategies.
For the care recipients: Care recipients will receive the Montreal Cognitive Assessment (MoCA) measure to assess their mental status at baseline. The purpose of the Quality of Life - Alzheimer's Disease (QoL-AD) measure is to assess the caregiver intervention affects the care recipient's quality of life. The total time to complete these questionnaires is about 30 minutes per session.
Participants not randomized to the active intervention will receive educational materials/pamphlets on dementia and occasional phone-calls by research assistants to maintain contact, as is the standard of care in most caregiver intervention studies. Including a control condition will allow for mirroring of the actual larger trial as closely as possible, and also ascertain the feasibility of randomization.
