About this study
Official title: Effects of a Home Based, Dyadic Multisensory and Cognitive Stimulation (MCS) Program for the People With Dementia and Their Family Caregivers: a Pilot Quasi-experimental Study
Although multisensory and cognitive stimulation therapy was shown as an effective intervention in improving cognition and behavioral symptoms of people with dementia (PWD), it is not commonly found as an element in the previous dyadic interventions. It was believed that the involvement of the family caregivers in multisensory and cognitive stimulation therapy could produce additional benefits to both PWD and caregivers by enhancing their interactions. Therefore, we will conduct a pilot study which aims to explore the feasibility and the effects of a home based dyadic multisensory and cognitive stimulation (MCS) program for the PWD and their family caregivers followed by a randomized controlled trial (RCT). In the RCT, the intervention group will attend the home-based dyadic MCS group, while the control group will receive the usual care. The outcomes measurements of caregivers (positive caregiving experience, perceived stress, caregiver burden, and quality of life) and PWD (cognitive function and behavioral symptoms) will be assessed at baseline, immediately post intervention, and 3 month-follow up. To understand the therapeutic components and identify the strengths, limitations and difficulties of the home based dyadic MCS program, process evaluation will be conducted through semi-structured focus group interviews with 15 participants from the MCS group. It is hypothesized that the MCS group will have a significant improvement on positive caregiving experience, perceived stress, caregiver burden, and quality of life of caregivers and cognitive function and behavioral symptoms of PWD.

Background:
Dementia becomes a major issue of worldwide concern. According to the World Alzheimer Report, the number of patients with dementia (PWD) worldwide was estimated at 46.8 million and it will be triply projected to 131.5 million in 2050. Similarly, dementia is also a prominent problem in Hong Kong. One in every three local seniors who are over 895 years of age suffered from dementia. The prevalence of PWD in Hong Kong will have a triple increase from 100,000 cases in 2009 to 300,000 cases in 2039.As the disease progresses, PWD will gradually lose their self-care ability and their cognitive function. In addition, behavioral symptoms such as agitation, delusion, and anxiety will appear on the sufferers. The caring burden and the uncertainty about the disease progress result in high levels of caring stress and negative emotion on family caregivers.
Nowadays, different psychosocial interventions have been designed for the PWD and their family caregivers to promote their psychological well-being. The dyadic intervention is deemed as one of the effective approach due to its mutual influence between the PWD and their family caregivers. A systematic review with 40 clinical trials found that dyadic approach can be integrated into different interventions such as psycho-education, and caring skills training . Although cognitive stimulation and multisensory stimulation therapy are regarded as an effective intervention for the cognition and the behavioral symptoms of the PWD, it is not commonly found as an element in the previous dyadic interventions. Involving family caregivers in a cognitive training can have some potential benefits for both caregivers and the PWD (e.g. cognitive function of the PWD and the quality of life) . The involvement of the family caregivers in the cognitive and multisensory stimulation therapy could promote the interactions between the PWD and caregivers which may produce additional benefits for both caregivers and the PWD, compared with the traditional cognitive stimulation therapy.
Objective:
The study aims to investigate the effects of the home based dyadic Multisensory and cognitive stimulation (MCS) intervention for the family caregivers of PWD in improving their positive aspects of caregiving, stress, depression, quality of life, and burden; and the cognitive function and behavioral symptoms of the PWD immediate post-intervention (T1) and, 3-month follow-up (T2), compared with the control group.
Methods:
A two- arm randomized controlled trial will be adopted to achieve the research objectives. After considering the number of group size and previous studies about the sample size, a total of 60 subjects (120 pairs of dyads-PWD and caregivers) will be recruited from four elderly community centers in Hong Kong with convenience sampling.
Participants from the Intervention group will attend the home-based dyadic MCS group, while the control group will receive the usual care. The outcomes measurements of caregivers (positive caregiving experience, perceived stress, caregiver burden, and quality of life) and PWD (cognitive function and behavioral symptoms) will be assessed by a blinded assessor at baseline (T0), immediately post intervention (T1) , and 3 month-follow up (T2). To understand the therapeutic components and identify the strengths, limitations and difficulties of the home based dyadic MCS program, process evaluation will be conducted through focus group interviews with 15 MCS participants after the intervention. In order to obtain a broad spectrum of views about the intervention, participants will be purposely selected for interview based on their level of stress reduction after the intervention.
IBM SPSS 23.0 will be used for the data analyses. Mixed multi-variate modeling or MANOVA test will be performed to investigate the between-group effect, the within-group effect (Times: T0, T1, and T2) and the interaction effect (Group x Time) on all of the outcomes variables. The last observation carried forward method will be adopted to replace the missing data if the missing value is in a small amount (<20%) and randomly distributed (Gray, Grove, \& Burns, 2013; Hamer \& Simpson, 2009). For the qualitative data, content analysis approach will be used to analyze all the transcribed interview verbatim.
Significance and Value:
The clinical project addresses the limitations of the previous psychosocial interventions and provides the PWD and their caregivers with an opportunity to improve the cognitive function of the PWD and promote the positive caregiving experience in the family caregivers which can reduce the caregivers' level of stress and improve the quality of life of the both family caregivers and the PWD. The findings from this projects can also inform the future direction in supporting the PWD and their family members and strengthen the nursing role in the community care.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dyadic MCS programBehavioural
In the first 4 weeks, the dyads will attend the center-based FTF sessions. Each session will last for 1.5 hours. In the first 60 minutes, MCS activities (e.g. reality orientation, calculation and drawing) will be led by an occupational therapist. Skills in delivering the MCS activities will also be taught to equip CG with skills in leading the home-based sessions later. CG will leave in the last 30 minutes to attend a psychoeducation group on caregiving (led by social workers) and the PWD will continue the session.
From week 5 onwards, The home based session (Week 5-15) will be delivered by the CG 3 times weekly at home (30 - 45min/ session).The sessions will be supplemented with weekly telephone follow-up and two FTF sharing sessions held on the 8th and 12th week over the period.
| Study group | Role | What they receive |
|---|---|---|
| Dyadic MCS program | Experimental | Participants from the experimental group will receive a dyadic multisensory and cognitive stimulation (MCS) programme.
The MCS program is a 15- week program. In the first 4 weeks, participants will attend the center-based Face-to-face (FTF) session twice a week (8 sessions), while in the remaining week (5th-15th Week), home-based sessions will be delivered by the caregivers with the PWD at home and was suggested to deliver the intervention 3 times/week at home. The home-based sessions will be supplemented with weekly telephone follow-up and two FTF sharing sessions over the intervention period. Receives: Behavioral: Dyadic MCS program |

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in positive caregiving experience before and after the intervention
The Change in caregivers' positive caregiving experience will be measured with the Chinese version of Positive Aspect of Caregiving scale (PAC). The PAC contains 11 items with 5-point Likert scale for all items responses. Scores for each items will be summed to compute a total score which ranges from 11 to 55, with higher scores indicating a more positive self-perceptions of caregiving.
Measured: T0 (baseline) and (T1) immediately post-intervention
Change in stress before and after the intervention
The change in caregivers' stress will be measured with the Chinese version of Perceived Stress Scale (PSS). The PSS contains 10 items with 5-point Likert-type scale rating from 0 (never) to 4 (very often). Scores for each items will be summed up to create a total score. The total score is ranged from 0-40, with higher score representing a higher level of perceived stress.
Measured: T0 (baseline) and (T1) immediately post-intervention
Change in caregivers' burden before and after the intervention
The change of caregiver's burden (only on caregivers) will be measured with the Chinese version of Zarit Burden Interview (ZBI). The scale comprises of 22 items including factors most frequently mentioned by caregivers as problem areas (e.g. caregivers' health, psychological well-being, finances, and social life). Caregivers will be asked to indicate the level of distress caused by each item, ranging from "not at all" to "extremely distressing," on a scale of 0 to 4. A total burden score will be obtained by adding up the scores for each response, with a possible total score ranging from 0 to 88. A higher score indicates greater caregiver distress.
Measured: T0 (baseline) and (T1) immediately post-intervention
Change in quality of life before and after the intervention
The World Health Organization Quality of Life (WHOQOL-OLD) short form will be used to assess the changes of caregivers' quality of life (QOL). The WHOQOL-OLD short form comprises of 6 old aged-specific quality of life items and each item is rated on a 5-point Likert-type scale that ranged from 1 (very dissatisfied) to 5 (very satisfied). Scores for each responses will be summed up to create a total score ranged from 6 to 30. A higher score indicates a better quality of life.
Measured: T0 (baseline) and (T1) immediately post-intervention
Change in depressive symptoms before and after the intervention
Depressive mood changes of caregivers will be measured with the Chinese version of Center for Epidemiological Studies Depression scale (CESD), which is a self-reported measurement on depression containing 20 items. Ratings were based on a 4-point Likert scale ranging from 0 (rarely or none of the time) to 3 (most or all of the time). Items for each responses will be summed up to create a total score ranging from 0 to 60. A higher CESD score indicates a higher level of depression.
Measured: T0 (baseline) and (T1) immediately post-intervention
Secondary outcomes (2)
Change in cognitive functions of the PWD before and after the interventions
Montreal Cognitive Assessment 5-min protocol (MoCA-5-min) will be used to assess changes on PWD' cognitive function over the telephone. The MoCA 5-min protocol consists of four subtests examining five cognitive domains, including attention, verbal learning and memory, executive functions/language, and orientation. Total score of the MoCA 5-min protocol range between 0 and 30, with higher score representing a higher level of cognitive functioning.
Measured: T0 (baseline) and (T1) immediately post-intervention
Change in behavioral and psychological symptoms of the PWD before and after the intervention
Change in behavioural and psychological symptoms of PWD will be measured by the Chinese version of the Neuropsychiatric Inventory-Questionnaire (NPI-Q). NPI-Q is an informant-based instrument that measures the presence and severity of 12 Neuropsychiatric Symptoms (NPS) in patients with dementia and caregivers distress. The caregivers will be asked to identify whether the symptoms of the PWD had been present in the past week, and rate the severity of the symptoms (from a Likert scale ranged from 1 to 3) and the corresponding distress to them (from a Likert scale ranged from 1 to 5). The NPI-Q provides two subscores- total Severity of symptoms and total distress scores. Higher score on these two subscales represent a higher level of symptoms severity of PWD and distress.
Measured: T0 (baseline) and (T1) immediately post-intervention

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Although multisensory and cognitive stimulation therapy was shown as an effective intervention in improving cognition and behavioral symptoms of people with dementia (PWD), it is not commonly found as an element in the previous dyadic interventions. It was believed that the involvement of the family caregivers in multisensory and cognitive stimulation therapy could produce additional benefits to both PWD and caregivers by enhancing their interactions. Therefore, we will conduct a pilot study which aims to explore the feasibility and the effects of a home based dyadic multisensory and cognitive stimulation (MCS) program for the PWD and their family caregivers followed by a randomized controlled trial (RCT). In the RCT, the intervention group will attend the home-based dyadic MCS group, while the control group will receive the usual care. The outcomes measurements of caregivers (positive caregiving experience, perceived stress, caregiver burden, and quality of life) and PWD (cognitive function and behavioral symptoms) will be assessed at baseline, immediately post intervention, and 3 month-follow up. To understand the therapeutic components and identify the strengths, limitations and difficulties of the home based dyadic MCS program, process evaluation will be conducted through semi-structured focus group interviews with 15 participants from the MCS group. It is hypothesized that the MCS group will have a significant improvement on positive caregiving experience, perceived stress, caregiver burden, and quality of life of caregivers and cognitive function and behavioral symptoms of PWD.

| Dyadic MCS programIn the first 4 weeks, the dyads will attend the center-based FTF sessions. Each session will last for 1.5 hours. In the first 60 minutes, MCS activities (e.g. reality orientation, calculation and drawing) will be led by an occupational therapist. Skills in delivering the MCS activities will also be taught to equip CG with skills in leading the home-based sessions later. CG will leave in the last 30 minutes to attend a psychoeducation group on caregiving (led by social workers) and the PWD will continue the session. From week 5 onwards, The home based session (Week 5-15) will be delivered by the CG 3 times weekly at home (30 - 45min/ session).The sessions will be supplemented with weekly telephone follow-up and two FTF sharing sessions held on the 8th and 12th week over the period. | Behavioural | Dyadic MCS program |
Primary outcome
Change in positive caregiving experience before and after the intervention
Time frame: T0 (baseline) and (T1) immediately post-intervention
The Change in caregivers' positive caregiving experience will be measured with the Chinese version of Positive Aspect of Caregiving scale (PAC). The PAC contains 11 items with 5-point Likert scale for all items responses. Scores for each items will be summed to compute a total score which ranges from 11 to 55, with higher scores indicating a more positive self-perceptions of caregiving.
Change in stress before and after the intervention
Time frame: T0 (baseline) and (T1) immediately post-intervention
The change in caregivers' stress will be measured with the Chinese version of Perceived Stress Scale (PSS). The PSS contains 10 items with 5-point Likert-type scale rating from 0 (never) to 4 (very often). Scores for each items will be summed up to create a total score. The total score is ranged from 0-40, with higher score representing a higher level of perceived stress.
Change in caregivers' burden before and after the intervention
Time frame: T0 (baseline) and (T1) immediately post-intervention
The change of caregiver's burden (only on caregivers) will be measured with the Chinese version of Zarit Burden Interview (ZBI). The scale comprises of 22 items including factors most frequently mentioned by caregivers as problem areas (e.g. caregivers' health, psychological well-being, finances, and social life). Caregivers will be asked to indicate the level of distress caused by each item, ranging from "not at all" to "extremely distressing," on a scale of 0 to 4. A total burden score will be obtained by adding up the scores for each response, with a possible total score ranging from 0 to 88. A higher score indicates greater caregiver distress.
Change in quality of life before and after the intervention
Time frame: T0 (baseline) and (T1) immediately post-intervention
The World Health Organization Quality of Life (WHOQOL-OLD) short form will be used to assess the changes of caregivers' quality of life (QOL). The WHOQOL-OLD short form comprises of 6 old aged-specific quality of life items and each item is rated on a 5-point Likert-type scale that ranged from 1 (very dissatisfied) to 5 (very satisfied). Scores for each responses will be summed up to create a total score ranged from 6 to 30. A higher score indicates a better quality of life.
Change in depressive symptoms before and after the intervention
Time frame: T0 (baseline) and (T1) immediately post-intervention
Depressive mood changes of caregivers will be measured with the Chinese version of Center for Epidemiological Studies Depression scale (CESD), which is a self-reported measurement on depression containing 20 items. Ratings were based on a 4-point Likert scale ranging from 0 (rarely or none of the time) to 3 (most or all of the time). Items for each responses will be summed up to create a total score ranging from 0 to 60. A higher CESD score indicates a higher level of depression.
2 secondary outcomes
Change in cognitive functions of the PWD before and after the interventions
Time frame: T0 (baseline) and (T1) immediately post-intervention
Change in behavioral and psychological symptoms of the PWD before and after the intervention
Time frame: T0 (baseline) and (T1) immediately post-intervention
