About this trial

The global cost of dementia is over 818 billion, and a further rise is expected in the next decade. While family caregiving is the backbone of the formal care service, promoting "living well with dementia" needs to extend to a dyadic perspective to address the needs of persons with dementia (PwD) and their caregivers. Unique to dementia caregiving, imbalanced exchange in the assistance, interaction, relationship and autonomy between the partners in a care dyad always challenges their social interaction and relationships. Such eroding dyadic dynamics not only worsens the mental health of caregivers, but also compromises the quality of caregiving, fosters more dementia deterioration, and eventually complicates the caregiving process. Nevertheless, least attention is directed to dyadic dynamics in promoting living well with dementia. Partner exercise is designed in a way which requires collaboration of two members to enable the workout of each other. In addition to the benefits of exercise on dementia symptom control and caregiver's stress management, partner exercise provides a meaningful encounter to encourage reciprocity, collaboration and relationship closeness within the care dyad.

This is a sequential mixed-method study including a multicenter RCT to evaluate the effects of the 16-week enhanced BUDPA and a descriptive qualitative study to explore the care dyad's overall engagement experience and perceptions. The study will be conducted in 8 elderly community centres operated by four NGOs.

The primary aim of the study investigates the effects of a 16-week enhanced BUDPA program on the health and dyadic dynamic of the persons with dementia and their family caregivers (Objective 1-3). The secondary aim explores dyads' overall experience in program engagement, particularly in terms of perceived benefits, challenges, and experience in self-directed practice (Objective 4). The primary outcomes include PwD's cognitive function and caregivers' mood status.

We hypothesize that the 16-week enhanced BUDPA program will be more effective than usual care immediately post-test (T1: week 16) and 3 months (T2: week 29) and 6 months thereafter (T3: week 42) in:

1. improving cognitive function, NPS and HRQL of persons with mild to early-moderate dementia. 2. improving the affect, positive aspects of caregiving, and HRQL of family caregivers. 3. improving the dyadic dynamic between the person with dementia and family caregiver in a dyad.

Treatments tested in this trial

  • Buddy-Up Dyadic Physical Activity (BUDPA) program

    Other intervention

    BUDPA program is an overall 16-week training which comprises three phases: the conditioning, consolidating and habituating phases. i) Conditioning Phase (1st - 4th week) is the preparatory phase to introduce exercise movements in group training. ii) Consolidating Phase (5th -12th week) is the training phase for group-based exercise. Each exercise training session will be followed by a 20-min debriefing and goal-setting session. Self-practice will be recorded on a simple logbook. iii) Habituating phase (13th-16th week) aims at supporting the care dyad to integrate the partner exercises into their daily lifestyle. A video call meeting with the care dyad in week 13 and week 15 will be scheduled to offer the support.

  • Usual care with waitlist control

    Other intervention

    The usual care such as dementia or caregiver support services, will be provided by the elderly community centres with a waitlist execute after the last assessment time point T3

Secondary outcomes

1

Medical Outcomes Study Short Form Health Survey (SF-12)

evaluates the health-related quality of life (HRQL) of the family caregiver, scales from 12 to 60, with higher score indicating better HRQL

Time frame
baseline (T0), immediately post-test (T1: week 16) and 3 months (T2: week 29) and 6 months thereafter (T3: week 42)
2

baseline (T0), immediately post-test (T1: week 16) and 3 months (T2: week 29) and 6 months thereafter (T3: week 42)
3

Positive Aspect of Caregiving Scale (PAC)

evaluate caregiver\'s gain in terms of self -affirmation and outlook on life, scales from 0 to 44, with higher scores indicating more positive caregiving gain
