- Brief Summary
The purpose of this study is to develop and implement a culturally-appropriate intervention to reduce stress in Vietnamese dementia caregivers. A pilot intervention will be done to test the feasibility and acceptability of the intervention in a community setting. This will be done by randomly assigning a family triad (primary caregiver, secondary caregiver, and their care recipient) into an active intervention or a control condition and monitoring findings at baseline, post-intervention, and at three months.The intervention will consist of multiple components -enhanced psycho-education that includes discussion of Alzheimer's Disease (AD) and cultural impacts on beliefs about dementia and caregiving, management of problem behaviors, facilitation of support seeking, and mindful Tai Chi. A secondary caregiver who the primary caregiver identifies as providing him/her with the most support will be invited to join all components, but the intervention will be flexible depending on caregivers' needs/preferences. The care recipient is not required to join the sessions but will be able to if he/she or the family wishes. During the intervention, community partners will provide respite care for the care recipient.
- Detailed Description
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.

- Primary Outcome Measures
Name Time Method Caregiver Intervention Adherence assessed at end of study, once all 3-month follow-ups are complete % of dyads engaging in the initial session, % completing at least 3 sessions, and % completing all sessions
Administration of Study Measures assessed at end of study, once all 3-month follow-ups are complete % of baseline, post-, and 3-month assessments completed (considering length of assessments and completeness of collected data
Acceptability 2 years Assessed through a questionnaire and interview assessing the perceptions of the intervention by primary and secondary caregivers, CBO staff/administrators, and interventionists.
Treatment Fidelity assessed once all 3-month follow-ups are complete Extent to which the facilitator adheres to the intervention protocol, as measured by a self-report checklist, with a goal of 85% adherence to key elements
Randomization assessed once all 3-month follow-ups are complete % of eligible dyads who agree to randomization
Retention assessed once all 3-month follow-ups are complete Retention in both arms of the study; Note: no formal assessment tool will be used - this will be assessed via number of participants retained
- Secondary Outcome Measures
Name Time Method Zarit Burden Inventory (ZBI) Baseline, 6-weeks (Post-intervention), 3 months post-intervention This is a caregiver self-report measure that contains 22 items. Each item on the interview is a statement which the caregiver is asked to endorse using a 5-point scale. Response options range from 0 (Never) to 4 (Nearly Always).
Quality of Life - Alzheimer's Disease (QoL-AD) Baseline, 6-weeks (Post-intervention), 3 months post-intervention The QOL-AD is a brief, 13-item measure designed specifically to obtain a rating of the patient's Quality of Life from both the patient and the caregiver. It was developed for individuals with dementia, based on patient, caregiver, and expert input, to maximize construct validity, and to ensure that the measure focuses on quality of life domains thought to be important in cognitively impaired older adults. It uses simple and straightforward language and responses \& includes assessments of the individual's relationships with friends and family, concerns about finances, physical condition, mood, and an overall assessment of life quality.
Center for Epidemiological Studies Depression (CES-D) scale Baseline, 6-weeks (Post-intervention), 3 months post-intervention This is a self-report depression scale that asks how many times during the past week a person has felt symptoms of depression. There are 20 items.
Perceived Stress Scale Baseline, 6-weeks (Post-intervention), 3 months post-intervention This scale asks subjects about how often they have felt or thought about 10 items during the past month.
Caregiver Self-Efficacy Baseline, 6-weeks (Post-intervention), 3 months post-intervention Asks the caregiver about how confident in their ability to keep up their own activities and also respond to caregiving situations. The Scale includes 10 items, and asks caregivers to rate their confidence in handling situations on a scale from 1 to 10.
Alzheimer's Disease Knowledge Scale (ADKS) Baseline, 6-weeks (Post-intervention), 3 months post-intervention This scale assesses knowledge about AD. The scale has 30 statements. Subjects are asked to rate each statement as True or False.
