Background Informal caregivers of persons with dementia (PWD) often suffer adverse impacts on their mental health and require interventions for effective support. As they are often occupied with providing care, web-based interventions could be more convenient and efficient for them. However, there is currently a dearth of evidence-based mobile interventions to enhance the mental well-being of dementia caregivers locally, especially ones that are user-centered and culturally relevant. Hence, having designed an app based on feedback from local dementia caregivers, this study will evaluate the effectiveness of this mobile app in promoting the mental health of informal caregivers of PWD in Singapore. Methods A pilot two-armed randomised controlled trial will be conducted on 60 informal caregivers of PWD recruited via convenience and snowball sampling. Thirty participants will be assigned to the intervention group, while another 30 will be in a waiting-list control group. Questionnaires will be administered at baseline and one month after, with the primary outcome being the difference in the change of depressive symptoms among the two groups. Statistical analysis Primary analyses will follow the intention-to-treat principle and compare changes from baseline to the one-month follow-up time point relative to the control group. A repeated measures ANOVA will be conducted to examine differences between the groups over time. Significance To our knowledge, this is the first study in Singapore that seeks to promote the mental health of informal dementia caregivers through a mobile-based intervention. The findings can inform the development and evaluation of future evidence-based digital interventions for local informal caregivers of PWD to address the gap in availability of such resources for them.

Background Qualitative evidence suggests that caregivers may express a wish for death of persons with severe dementia (PwSD). No study has assessed the extent to which it happens, stability of this wish over time and the factors associated with it. Objectives We examined caregivers’ wish for death of PwSDs overtime and the factors associated with this wish. Methods 215 caregivers of community dwelling PwSDs were surveyed every 4 months for 2 years. Using the mixed-effects multinomial regression model, we assessed the PwSD and caregiver factors associated with caregivers’ wish for PwSDs’ death. Results At baseline, 27% caregivers expressed a wish for PwSDs’ life to end sooner. Overall, 43% of the caregivers expressed a wish for PwSDs’ death at least once during the study period and 11% expressed it consistently. Caregivers’ perception of PwSDs’ lower quality of life (RRR: 1.05, 95% CI: 1.00, 1.10), higher functional dependency (RRR: 1.1, 95% CI: 1.01, 1.21), eating difficulty (RRR: 2.25, 95% CI: 1.26, 4.04) and suffering (RRR: 1.92, 95% CI: 1.05, 3.52) were associated with this wish. Caregivers who were emotionally close to PwSDs were less likely (RRR: 0.25, 95% CI: 0.11, 0.55) while those who understood that dementia is a terminal illness were more likely (RRR: 2.01, 95% CI: 1.03, 3.92) to express this wish. Conclusion Caregivers’ wish for PwSDs’ death changed over time and was primarily driven by their perception of PwSDs’ poor well-being and awareness of their illness being terminal, indicating a need for increased support in this challenging caregiving context.

Aims The Institute of Mental Health is the only tertiary Psychiatric Hospital in Singapore. It has two 29 bedded inpatient wards which provides acute care for the elderly with severe mental health problem. Over the past year there has been a trend of an increasing number of elderly patients who stay for a prolonged period of time as they require long term care placement and this increased length of stay leads to increasing healthcare costs, a reduction in availability of acute beds which in turn leads to elderly patients needing to be lodged in general adult wards. In 2022 the average length of stay for the elderly wards was 46 days as compared to the target of 21 days set by the hospital. Prolonged inpatient stays can lead to physical decompensation including reduced muscle strength, pulmonary capacity and osteoporosis. Methods We conducted a retrospective audit on 30 patients who were admitted between July and December 2022, requiring long term care placements. Our hypotheses were that patients with a diagnosis of dementia, who were frail and with caregiver burnout were more likely to require long term care placement. We subsequently designed a data collection form to collect the latter data and analysed them. Results Out of the 30 patients, 27 (90%) had a diagnosis of dementia, 25 (83.3%) were classified as frail (6 or more on the clinical frailty scale) and 23 (76.6%) had caregiver burnout, 12 (40%) family unable to look after patients in spite of community support and 3 (10%) had no next of kin. Conclusion Patients with dementia and frailty are more likely to require long term care placements. In the inpatient unit, we find that caregivers of these patients are burnt out because of their behaviour problems. We are embarking on an enriched model of care to reduce severe behavioural and psychological symptoms of dementia thereby reducing the need for restraints and its associated complications, and empowering caregivers to manage their behaviour problems. This audit also stressed the importance of addressing issues upstream. Referrals to community facilities like day care which provide exercise and rehabilitation for the elderly will help delay the consequences arising from frailty. We are also partnering primary care to assist with early identification of dementia and providing early interventions to prevent caregiver burnout.

Background Positive aspects of caregiving are important coping resources for informal caregivers of persons with dementia (PWD). However, existing studies mostly focused on caregivers from western societies and less attention was paid to the potential cultural differences. This study aims to explore positive aspects of caregiving in the Asian context. Methods A qualitative methodology with semi-structured interviews was adopted. A total of 29 informal caregivers of PWD in Singapore were interviewed from Apr 2019 to Dec 2020. All the interviews were audio-recorded and transcribed verbatim for the analysis. Inductive thematic analysis was conducted. Results The results revealed a total of three major themes with 11 sub-themes including: 1) positive aspects within self (i.e., better understanding of dementia and caregiving, personal growth, role satisfaction, and improved awareness of self-care); 2) positive aspects between caregiver and PWD (i.e., chance to demonstrate filial piety towards PWD, happiness and positive attitudes of PWD, positive interactions with PWD, and closer relationships with PWD); and 3) positive aspects between caregiver and others (i.e., empathy towards other caregivers, befriending peers, and sharing dementia and caregiving knowledge with others). Discussion Findings from this study improved our understanding on positive aspects of caregiving among informal caregivers of PWD in the Asian context. In addition to similar themes across cultures such as personal growth, our study identified a few unique themes like improved awareness of self-care and chances to demonstrate filial piety. For future studies targeting Asian caregivers, it is necessary to include these cultural-specific positive aspects of caregiving.

Background Informal caregivers of persons with dementia (PWDs) sometimes engage foreign domestic workers (FDWs) to support their caregiving journey. However, there has not been much research to establish if this is really beneficial. The current study aims to investigate whether engaging FDWs specifically for caregiving of PWDs truly moderates caregiver stress and to explore caregivers’ experiences of engaging FDWs. Methods A multi-method study design with a quantitative and qualitative sub-study was adopted. For the quantitative sub-study, 282 informal caregivers of PWDs were recruited. Propensity score matching analysis was used. For the qualitative sub-study, 15 informal caregivers with FDWs were interviewed. Inductive thematic analysis was conducted. Results The quantitative sub-study confirmed that engaging FDWs did moderate the depressive symptoms of informal dementia caregivers (marginal effect = -3.35, p = 0.0497). However, such support did not affect their caregiving burden, self-efficacy, and perceived positive aspects of caregiving. The qualitative sub-study suggested that engaging FDWs is an ambivalent experience, which entails both support and challenges. Conclusions The current study confirmed previous research findings, that engaging FDWs moderated depressive symptoms among caregivers of PWDs, and it could be through their physical support such as in daily caregiving activities. Policy-makers may consider providing more subsidies to caregivers caring for PWDs with mobility issues to hire FDWs. They may also consider providing training to FDWs on dementia caregiving skills and improving the intake of such training as this might be helpful for both FDWs and caregivers during this journey.

Background Informal caregivers of persons with dementia often experience elevated levels of caregiving burden. However, existing studies tend to use a variable-centered approach to explore it. This study aims to understand the caregiving burden of informal caregivers of persons with dementia in Singapore through a combination of variable-centered and person-centered analytical approaches, and explore the correlates of identified factors and latent classes of caregiving burden. Methods Zarit Burden Interview was used to gauge the caregiving burden of 282 primary informal caregivers of persons with dementia recruited through convenience sampling in Singapore. Factor analysis and latent class analysis were conducted to identify the latent factors and the latent classes of Zarit Burden Interview, followed by multiple linear regression and multinomial logistic regression to explore their significant correlates. Results The analyses suggested a 17-item 3-factor structure for Zarit burden interview and three mutually exclusive caregiving burden classes. Regression analyses found that caregiving related variables especially care recipients’ memory and behaviour problems were correlated with both the factors and latent classes of caregiving burden. Conclusions The combination of these two approaches suggests that caregivers experiencing higher burden on one domain are likely to experience higher burden on the other two domains. This further supports the point that more attention should be given to caregivers who experience an overall high burden. Future research could explore the generalizability of our findings among caregivers elsewhere and explore the type of support needed by caregivers, especially those experiencing high burden.

Background: Informal caregivers of persons with dementia (PWD) are often associated with negative health outcomes. Self-efficacy in dementia caregiving has been reported to have protective effects on caregiver's health. This study aims to examine the factors associated with the domains of caregiving self-efficacy among informal caregivers in Singapore, a country with a rapidly aging population and a 10% prevalence of dementia among older adults. Methods: Two hundred eighty-two informal caregivers were recruited and data including participant's caregiving self-efficacy, sociodemographic information, perceived social support, positive aspects of caregiving, knowledge of dementia, as well as behavioral and memory problems of care recipients were collected. A confirmatory factor analysis (CFA) was performed for the 3-factor model of the Revised Scale for Caregiving Self-Efficacy (RSCSE), and multiple linear regressions were conducted using the RSCSE subscales as dependent variables. Results: Our CFA found that the RSCSE 3-factor model proposed by the original scale developer was an acceptable fit among informal caregivers in Singapore. Having established that the 3-factor model of the RSCSE was compatible among our sample, a series of multiple regressions were conducted using each of the factors as a dependent variable. Regressions revealed several factors that were significantly associated with caregiving self-efficacy. Importantly, outlook on life was positively associated to all 3 domains of the RSCSE, while social support was positively associated with self-efficacy in obtaining respite and controlling upsetting thoughts. Conclusion: The 3-factor model of the RSCSE was found to be an appropriate fit for our sample. Findings from this study elucidated important novel insights into the factors that influences caregiving self-efficacy amongst informal caregivers in Singapore. Crucially, caregivers' outlook on life and social support should be improved in order to enhance their caregiving self-efficacy.

Background The present study investigated the factor structure of positive aspects of caregiving (PAC) scale among primary informal caregivers providing care to persons with dementia (PWD) in Singapore. Methods 282 primary informal caregivers of PWD were recruited from the Institute of Mental Health, and Changi General Hospital and administered the 9-item PAC scale. A confirmatory factor analyses (CFA) was conducted to test the model fit of the 9-item PAC proposed by the scale developer and multiple linear regression was used to investigate the significant socio-demographic correlates. Results CFA showed that the 2-factor structure including ‘Self-Affirmation’ and ‘Outlook on Life’ had an acceptable model fit. After controlling for confounding variables, Malay caregivers were associated with higher scores on PAC and ‘Self-Affirmation’ compared to caregivers of other ethnicities. Caregivers with Secondary or below education level had higher PAC and ‘Outlook on Life’ scores. Caregivers who had received formal training scored higher in PAC, ‘Self-Affirmation’ and ‘Outlook on Life’. Discussion The present study confirmed that the 2-factor structure of the 9-item PAC was suitable for informal caregivers of PWD in Singapore. The findings have important implications for locally available interventions to enhance caregiver’s psychological well-being and reduce burden of care.

Background and objectives: Existing studies typically explore the factor structure of coping strategies among dementia caregivers. However, this approach overlooks the fact that caregivers often use different coping strategies simultaneously. This study aims to explore the coping patterns of primary informal dementia caregivers in Singapore, examine their significant correlates, and investigate whether different patterns would affect the depressive symptoms of caregivers. Research design and methods: Two hundred eighty-one primary informal caregivers of persons with dementia were assessed. Coping strategies were measured by the Brief Coping Orientation to Problem Experienced inventory. A latent class analysis was performed to explore caregivers' coping patterns, followed by logistic regressions to identify the significant correlates and the relationships between coping patterns and caregiver depression. Results: The latent class analysis suggested a 3-class solution that was featured by the frequency and variety of coping strategies used by caregivers - high coping (36.3%), medium coping (37.7%), and low coping (26.0%). Factors influencing the coping patterns of our sample were mainly related to caregivers' individual resources such as personal characteristics and caregiving stressors like PWD's problematic behaviours and caregiving burden. Compared to caregivers in the low coping group, those in the medium coping group had significantly higher risks of potential depression. Discussion and implications: The current study confirmed that there are distinct coping patterns among primary informal dementia caregivers, and caregivers with the low coping pattern had fewer depressive symptoms. Future research is needed to explore if coping patterns from our sample are generalizable to dementia caregivers elsewhere.

Although many persons with severe dementia (PWSDs) are cared for at home by their family caregivers, few studies have assessed end of life (EOL) care experiences of PWSDs. We present the protocol for the Pisces study (Panel study Investigating Status of Cognitively impaired Elderly in Singapore) which aims to describe the clinical course, health care utilization, and expenditures for community-dwelling PWSDs; and perceived burden, coping, resilience, anticipatory and prolonged grief among their caregivers. This ongoing multi-center prospective longitudinal study is recruiting primary informal caregivers of 250 PWSDs from major restructured public hospitals, community hospitals, home care foundations, and hospices in Singapore. Caregivers are surveyed every four months for two years or until the PWSD passes away and then at eight weeks and six months post-death to assess the bereavement of the caregiver. Survey questionnaires included validated tools to assess PWSDs' quality of life, suffering, behaviors, functional status, resource utilization; and caregiver's satisfaction with care, awareness of prognosis, care preferences, resilience, coping, perceived burden, distress, positive aspects of caregiving, anticipatory grief, and bereavement adjustment. We also conduct qualitative in-depth interviews with a sub-sample of caregivers. The survey data is being linked with medical and billing records of PWSDs. The study has been approved by an ethics board. Results from the study will be disseminated through publications and presentations targeting researchers, policy makers and clinicians interested in understanding and improving EOL care for PWSDs and their caregivers.
