Brief Summary

In the realm of dementia care, the imperative to intervene at the earliest stages of cognitive decline is paramount. Recognizing this pivotal moment, the development of innovative and effective interventions becomes imperative in delaying dementia progression.

Rooted in the Roy Adaptation Model and Zimmer's Theory of Psychological Empowerment, the investigator team has developed the empowerment-based dyadic strength-based intervention, which integrates strength-based and empowerment methodologies. Emphasizing a shift from deficits to capabilities, the strength-based approach fosters awareness of collective strengths within care dyads, facilitating coping mechanisms and resilience in the face of cognitive afflictions.

Detailed Description

In the realm of dementia care, the imperative to intervene at the earliest stages of cognitive decline is paramount. Recognizing this pivotal moment, the development of innovative and effective interventions becomes imperative in delaying dementia progression.

Rooted in the Roy Adaptation Model and Zimmer's Theory of Psychological Empowerment, the investigator team has developed the empowerment-based dyadic strength-based intervention, which integrates strength-based and empowerment methodologies. Emphasizing a shift from deficits to capabilities, the strength-based approach fosters awareness of collective strengths within care dyads, facilitating coping mechanisms and resilience in the face of cognitive afflictions.

The objective of this study is:

1. To study the effectiveness of ambassador-led strength-based intervention for patient-participants with dementia living in the community and residential units to enhance their quality of life;

2. To compare how the involvement of young-old volunteers in the strength-based intervention enhance service effectiveness

After obtained the consent baseline data collection will be done. The participants will be randomized to receive either the ambassador-led strength-based intervention of usual care group. The post-test data collection will take place upon the completion of the program (9th week) and at 3-month thereafter.

The Strength-based intervention incorporates 8-week Ambassador-led strength-based intervention including:

1. a strength-based assessment to the patient-participant and caregiver done by the Social Worker,

2. Ambassador-assisted preparation of the strength-based biography,

3. four Ambassador-led workshops, the workshop will be delivered in group of 6-8 participants by at least 2 Ambassadors, and

4. one Social Worker-led zoom video conference delivered to the caregivers.

Primary Outcome Measures

Name	Time	Method
A battery of cognitive assessments (CAB)	3 months after the posttest (T2)	evaluate the global cognition sore by the Alzheimer's Disease Assessment Scale -Cognitive Subscale (ADAS-Cog), the digit span-forward and backward test for attention and working memory, the list learning delayed recall test for episodic memory, 5-min Montreal Cognitive Assessment and Trail-Making Test for complex attention, executive function and task switching. The higher score indicates poor cognitive function
Quality of Life-Alzheimer's Disease (QoL-AD)	3 months after the posttest (T2)	evaluate the health-related quality of life (HRQL) covering physical, functional, psychosocial, interpersonal, and environmental status of the patient with dementia, scales 13 to 52, with higher score indicating better HRQL
the 10-item Center for Epidemiologic Studies Depression Scale (CES-D)	3 months after the posttest (T2)	evaluate the changes in participant's mood status. The response set is a 4-point Likert scale, scale from 0-30, with a higher score indicating a higher level of depression.
Dyadic Relationship Scale - Patient version (DRS-patient)	3 months after the posttest (T2)	evaluate the quality of interpersonal relationships in the caregiving dyad, in the care recipient perspective. It measures aspects such as communication, support, and satisfaction within the dyad, providing insight into the dynamics of caregiving relationships in dementia care settings. It scale from 0-30 with a higher score indicating a better dyadic relationship.
Dyadic Relationship Scale - Caregiver version (DRS-caregiver)	3 months after the posttest (T2)	evaluate the quality of interpersonal relationships in the caregiving dyad, in the caregiver perspective. It measures aspects such as communication, support, and satisfaction within the dyad, providing insight into the dynamics of caregiving relationships in dementia care settings. It scale from 0-33 with a higher score indicating a better dyadic relationship.
The Revised Scale for Caregiving Self-Efficacy (RSCSE)	3 months after the posttest (T2)	evaluate the perceived self-efficacy in caregiving, to measure the caregivers' perceived self-efficacy in handling the symptoms of the persons with mild cognitive impairment and to control their own emotions. It scale from 0-100 with a higher score indicating a higher caregiving self-efficacy.
The Neuro-psychiatric Inventory (NPI)	3 months after the posttest (T2)	evaluate the neuro-psychiatric symptoms of the patient with dementia reported by the caregiver, scales from 12 to 96 with higher scores indicating higher severity
the Patient-Reported Mild Behavioral Impairment Scale	3 months after the posttest (T2)	evaluate the behavioral changes associated with cognitive decline for those with mild cognitive impairment, which enables patients to self-report symptoms, aiding in early detection and intervention for mild behavioral impairment, a potential precursor to dementia. It scale from 0-102 with a higher score indicating a higher risk of behavioral changes associated with cognitive decline.
