Psychological distress in informal caregivers of patients with dementia in primary care: course and determinants

Older caregivers' depressive symptomatology over time: evidence from the Survey of Health, Ageing and Retirement in Europe

The prevalence of informal caregiving is increasing as populations across the world age. Caregiving has been found to be associated with poor mental health outcomes including depressive symptoms. The purpose of this study is to examine the mean trajectory of depressive symptomatology in older caregivers in a large European sample over an eight-year period, the effects of time-varying and time-invariant covariates on this trajectory, and the mean trajectory of depressive symptomatology according to pattern of caregiving. The results suggest that depressive symptoms in the full sample of caregivers follow a nonlinear trajectory characterized by an initial decrease which decelerates over time. Caregiver status and depressive symptoms were significantly associated such that depressive symptoms increased as a function of caregiver status. The trajectory in caregivers who report intermittent or consecutive occasions of caregiving remained stable over time. Significant associations were found between sociodemographic, health and caregiving characteristics and the initial levels and rates of change of these trajectories. While these results point to the resilience of caregivers, they also highlight the factors that are related to caregivers' adaptation over time. This can help in identifying individuals who may require greater supports and, in turn, ensuring that caregivers preserve their well-being.

Psychological Distress, Multicare Needs and Social Resource Utilisation of Family Caregivers of People With Dementia: A Descriptive-Correlational Study

BACKGROUND

The population of people with dementia increases yearly, imposing a growing burden on family caregivers. Psychological distress impacts the mental health of family caregivers of people with dementia. Caregiver psychological distress can result in increased social resource utilisation and unmet multicare needs.

PURPOSE

The study explored the psychological distress of family caregivers of people with dementia and examined the impact on social resource utilisation and multicare needs.

METHODS

A descriptive-correlational study collected data in Taiwan from a cross-sectional sample of family caregivers of people with dementia using a self-report questionnaire. Data were analysed using linear and logistic regression.

RESULTS

A total of 301 caregivers provided data for analysis. Nearly two-thirds of caregivers were female with a mean age of 57 years old (SD = 12). Over half of the family caregivers of people with dementia experienced mild-to-moderate psychological distress. The greater the psychological distress, the greater the probability of using social resources (1.09 times per 1-point increase, p = 0.002). Psychological distress was positively associated with the number of caregivers' care needs (β = 0.371, p < 0.001).

CONCLUSIONS

Findings of this study can assist healthcare professionals in better understanding the psychological distress and care needs of caregivers. Services designed to meet the needs of family caregivers will improve psychological distress.

Burden and quality of life of family caregivers of Alzheimer's disease patients: the role of forgiveness as a coping strategy

OBJECTIVES

This study aimed to evaluate the variables that  were associated, contributed and moderated quality of life (QoL) and burden in family caregivers.

METHODS

A total of 130 participants were evaluated using the following instruments: Depression, Anxiety and Distress Scale; Index of Family Relations; Heartland Forgiveness Scale; Burden Interview Scale; Short Form Health Survey.

RESULTS

Being a younger caregiver, less distress, better family relationships and greater use of forgiveness were associated with more QoL. Also, family caregivers who chosethe caregiving role, less distress, better family relationships and greater use of forgiveness showed lower levels of burden. Age, distress and forgiveness contributed to QoL. In turn, the choice to become a family caregiver, distress, and forgiveness contributed to burden. Forgiveness played a moderating role in the relationship between family relationships and burden.

CONCLUSION

Based on the results, there is a need to intervene in older family caregivers, particularly those who did not choose to become a caregiver, who report greater distress, have worse family relationships, and display less use of forgiveness, in order to decrease their burden and promote QoL.

Virtual reality-based dementia educational programmes for formal and informal caregivers of people with dementia: A scoping review

AIM

To map evidence of the existing virtual reality-based dementia educational programmes and the effects of these educational programmes on dementia formal and informal caregivers.

DESIGN

A scoping review.

METHODS

A comprehensive search of nine databases was conducted to find studies from the inception of the databases to October 2023. Two authors independently screened the titles and abstracts related to the eligibility criteria. Full texts of potentially relevant studies were read by one author and checked by a second. Data extraction and synthesis using NVivo 12 were undertaken by one author and checked by two other authors.

RESULTS

Nineteen studies published between 2002 and 2022. The four randomised controlled studies and five qualitative studies were of moderate to good methodological quality. The 10 quasi-experimental studies were of weak to moderate quality. Fifteen virtual reality-based educational programmes had a positive influence on formal and informal caregivers, including improving caregivers' perceptions changing attitudes towards people with dementia, while the nursing competence of formal caregivers did not improve in short term. Educational programmes that covered dementia-related information and care strategies better improved the knowledge level of dementia formal and informal caregivers.

CONCLUSIONS

The qualitative and quantitative studies of moderate to good quality included in this study support the idea that virtual reality-based dementia educational programmes may be a safe and effective way and have potential benefits for improving knowledge, perceptions, attitudes and nursing competence.

IMPACT

This scoping review will provide an emerging teaching model for formal and informal caregivers of people with dementia and help them better understand the types and the influence of virtual reality-based dementia educational programmes.

Informal Caregivers of People with Dementia in Germany: Psychosocial Characteristics and Unmet Needs

Background

Caregivers of people with dementia living at home (CPwDh) are likely to be affected by a range of health problems. However, CPwDh are often regarded as accompanying persons and receive less attention in research and care. Little is known about this population and their needs in Germany. However, better knowledge of CPwDH is needed to design effective interventions.

Objective

The objective of this report is to describe the situation of CPwDh and highlight differences based on sex and living situation.

Methods

This was a cross-sectional analysis of the psychosocial characteristics of participants in the GAIN trial, a cluster-randomized, controlled intervention trial investigating the effectiveness of a care management program. A total of n = 192 CPwDh were recruited in GP offices, memory clinics or through public campaigns in the German federal state of Mecklenburg-Western Pomerania. The inclusion criteria were an age of 18 years or above, being a CPwDh, written informed consent. In a comprehensive digital assessment, psychosocial variables, burden, and care needs were assessed.

Results

Partners, women, and people living in the same household represented the majority of caregivers, and their mean number of needs was 8.7. Overall, participants indicated a mild to moderate burden. There are differences in burden based on sex and living situation, with caregivers living with people with dementia showing less burden and different psychosocial demographics.

Conclusions

There is a need for interventions to reduce caregivers' unmet needs in the CPwDh. Such interventions should consider differences in sex and living situation to better address individual caregiver needs.

A Double Whammy? Psychosocial Disadvantages of Dementia Caregivers with Cancer Histories

Guided by the Diathesis-Stress model, this study examined how cancer history interacted with caregiving status to determine the psychosocial functioning of dementia caregivers. This study assessed a set of indicators for psychological health and social connections among 85 spousal caregivers of persons with Alzheimer's disease and 86 age- and gender-matched spouses of healthy controls at study entry and 15-18 months later. Results showed that dementia caregivers with cancer histories reported lower social connections relative to caregivers without cancer histories or non-caregivers with or without cancer histories, and reported lower psychological health relative to non-caregivers with and without cancer histories at two time points. The findings highlight that a history of cancer is a predisposing vulnerability factor for psychosocial dysfunctions among dementia caregivers and address gaps in knowledge about the psychosocial adjustment of cancer survivors as caregivers.

"Better Living with Non-memory-led Dementia": protocol for a feasibility randomised controlled trial of a web-based caregiver educational programme

BACKGROUND

Non-memory-led dementias such as posterior cortical atrophy (PCA), primary progressive aphasia (PPA) and behavioural variant frontotemporal dementia (bvFTD) are low prevalent and often affect individuals under the age of 65. Tailored educational and support resources for caregivers of people living with these dementia phenotypes are scarce and unevenly distributed geographically. Web-based educational programmes are emerging as promising alternatives to improve caregiver self-efficacy and well-being. Here, we present the protocol of a study aiming to assess the feasibility of a co-produced online educational programme for caregivers of people living PCA, PPA and bvFTD: the Better Living with Non-memory-led Dementia programme.

METHODS

A randomised controlled feasibility trial will be conducted on a sample of 30 caregivers of people living with PCA, PPA and bvFTD. Participants will be recruited among members of the support organisation Rare Dementia Support (based at UCL in the UK). The intervention group will be given access to an 8-week co-produced web-based educational programme consisting of 6 modules addressing education about PCA, PPA and bvFTD and support strategies for the person with dementia and for the caregiver. The control group will receive treatment as usual (TAU). Feasibility will be measured through feasibility of recruitment, clinical measurement tools and acceptability. Clinical measures will be used to assess preliminary efficacy and data on completion rates, missing data and variability used to decide on measures to be included in a full-scale trial. Allocation ratio will be 2:1 (intervention:control) stratified by diagnosis. Feasibility of recruitment and acceptability will be assessed. Clinical measures will be administered at baseline and 8-week and 3-month post-randomisation. The control group will be offered access to the intervention at the completion of data collection. Participants will be unblinded, and all measures will be self-reported online.

DISCUSSION

Online-delivered educational programmes show potential for improving care competency of caregivers and may contribute to overcoming geographical inequalities in local provision of support services. This pilot study will inform a fully powered international trial to determine the effectiveness of Better Living with Non-memory-led Dementia.

TRIAL REGISTRATION

This trial has been registered prospectively on the Clinical Trials Registry on 1st September 2022, registration number NCT05525377.

Psychological interventions for symptoms of depression among informal caregivers of older adult populations: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Symptoms of depression are commonly experienced by informal caregivers of older adults, however there is uncertainty concerning effectiveness of psychological interventions targeting symptoms of depression in this population. Further, there is uncertainty concerning important clinical moderators, including intervention type and care recipient health condition. This review examined the effectiveness of psychological interventions targeting symptoms of depression in informal caregivers of older adults.

METHODS

PubMed, CINAHL, Embase, PsycINFO, Cochrane Library and Web of Science were searched. Risk of bias was assessed using the Cochrane Risk of Bias tool version 2.

RESULTS

Fifteen studies were identified and twelve (1270 participants) provided data for the meta-analysis. Interventions included cognitive behavioral therapy (4 studies), problem-solving therapy (4 studies); non-directive supportive therapy (4 studies) and behavioral activation (3 studies). A small effect size favouring the intervention was found for symptoms of depression (g = -0.49, CI = -0.79, -0.19, I² = 83.42 %) and interventions were effective in reducing incidence of major depression (OR = 0.177, CI = 0.08, 0.38), caregiver burden (g = -0.35, CI = -0.55, -0.15) and psychological distress (g = -0.49, CI = -0.70, -0.28). Given high heterogeneity, findings should be interpreted with caution. Overall risk of bias was high.

LIMITATIONS

Studies were limited to those in English or Swedish.

CONCLUSION

Psychological interventions may be effective in reducing symptoms of depression among informal caregivers of older adults. However, evidence is inconclusive due to heterogeneity, high risk of bias, and indirectness of evidence.

Suicide risk in caregivers of people with dementia: a systematic review and meta-analysis

BACKGROUND

Interest in physical and mental health outcomes in caregivers of patients with dementia is increasing. However, there is limited data available on the prevalence of suicidal ideation, suicidal attempts, and suicide rates among caregivers of those with dementia. Therefore, we aimed to systematically review these outcomes to address this gap in the literature and thus provide information to inform future policy and intervention for the benefit of caregivers of dementia patients.

METHODS

We searched several databases from inception to the 10th November 2021, for studies investigating suicidal ideation, suicidal attempts, and suicide rates of caregivers of patients with dementia. We report data regarding suicidal ideation as prevalence, with the 95% confidence intervals (CIs), applying a random-effect model; since less than three studies were available for suicide attempt and suicide, these data are reported descriptively.

RESULTS

Among 194 articles, eight comprising 1,209 informal caregivers of people with dementia (mean age: 63.9 years, 74% females) were included. The prevalence of suicide ideation was 32.32% (95% CI: 16.01-48.64%; I2 = 98.5%, p < 0.0001). The prevalence of suicide ideation varied between studies from 4.69% to 77.78%. Two studies reported the rate of suicidal attempt in caregivers of patients with dementia, with the prevalence ranging from 5.9% to 16.1%. One study reported one in 17 caregivers of patients with dementia died by suicide.

CONCLUSIONS

The prevalence of suicide ideation is high, affecting several caregivers of patients with dementia. These findings suggest intervention and/or policy are urgently needed to address suicidal behavior in this at-risk population.

Effects of App-Based Mobile Interventions for Dementia Family Caregivers: A Systematic Review and Meta-Analysis

BACKGROUND

Dementia was caregivers experience tremendous difficulties both physically and psychologically, leading to high levels of depression and caregiver burden. The advantage of mobile interventions has been recognized due to its freedom from time and space restrictions.

OBJECTIVES

A systematic review and meta-analysis was conducted to evaluate effectiveness of app-based mobile interventions for dementia caregivers.

METHOD

We searched nine different databases including CINAHL, the Cochrane Library, Embase, MEDLINE, PsycINFO, the ACM digital library, IEEE Xplore, KoreaMed, and RISS for publications on app-based mobile interventions targeting dementia caregivers published in English or Korean. Meta-analysis was conducted using Comprehensive Meta-Analysis (CMA) version 3.0. Standard mean difference (SMD) was used to estimate the effectiveness of the intervention on caregiver-related outcomes of caregiver burden, depression, stress, caregiving competency, and quality of life (QoL).

RESULTS

Five studies (three randomized controlled trials and two quasi-experimental studies) with a total of 230 participants were included. Using a mobile device, interventions were used to provide information and feedback, perform monitoring, and conduct skill training. Pooled analysis showed favorable effects of app-based mobile interventions for caregivers on caregiver burden (SMD = -0.315, 95% CI: -0.681 to 0.052), depression (SMD = -0.236, 95% CI: -0.517 to 0.046), stress (SMD = -0.295, 95% CI: -0.708 to 0.118), competency (SMD = 0.434, 95% CI: 0.093-0.775), and QoL (SMD = 0.794, 95% CI: 0.310-1.278).

CONCLUSION

Types of mobile devices, lengths, and contents of interventions varied between included studies. Given that only five studies were included, the current meta-analysis could not confirm the effectiveness of app-based mobile interventions. However, this study suggests that app-based mobile interventions for dementia caregivers might have positive effects on diverse caregiving-related issues such as caregiver burden, depression, stress, competency, and QoL.

Factors associated with the skills of informal caregivers in home care

ABSTRACT Objective: To identify factors associated with cognitive, emotional, psychomotor, and relational skills of informal caregivers in home care. Methods: A cross-sectional study carried out with a sample of 216 informal caregivers residing in a municipality in the state of Paraná. Data collection took place between February and July 2019, with an instrument developed and validated to assess the skills of informal caregivers. Descriptive and inferential analyses were used. Results: The factors associated with a greater competence of informal caregivers were being female, having training in the field, and having more than five years home care experience. The lowest competence was observed in caregivers who had health problems and belonged to the lowest strata of family purchasing power. Participants had lower scores in psychomotor competence and had better results in cognitive competence. Conclusion: It was found that women with experience in care had higher levels of competence to provide quality care at home assistance services.

Informal caregivers and psychosocial support: Analysis of European Dementia Policy documents

Various countries in Europe have different strategies for promoting care solutions for dementia challenges. The different approaches of Austria, Belgium, Czechia, Denmark, Finland, Germany, Gibraltar, Ireland, Israel, Malta, Nederland, Norway, Sweden and the United Kingdom (Scotland and Wales) were investigated. Dementia has a significant social, psychological and economic impact on the individual, family and society. As the disease progresses dementia sufferers become increasingly dependent. As many dementia sufferers are at home during the initial stages, the physical, emotional, and social demands of the dementia sufferers are often covered by informal caregivers. This study, therefore, aims to investigate the integration of psychosocial interventions for comprehensive care pertaining to informal caregivers of people with dementia in Europe. Furthermore, the study will highlight how implementation of technologies might enable psychosocial support of informal caregivers. The data is based on 15 national dementia strategies from various European countries. Data was based on preexisting coding systems with the predefined keywords and analyzed by qualitative content analysis by four of the authors. Our results show that psychosocial support is provided in various modalities and that informal caregivers need to be supported by a psychosocial approach. Due to this need the national dementia strategies should include measures to reduce the emotional burden of informal caregivers. Psychosocial support provided to informal caregivers in a comprehensive and systematic way is likely to enable informal caregivers to handle the emotional, cognitive, and behavioral consequences of the disease and its treatment, while helping to maintain their work-life balance.

The Trajectory of Caregiver Burden and Risk Factors in Dementia Progression: A Systematic Review

Background:

Caring for patients with dementia at home is often a long-term process, in which the independence of the patient declines, and more responsibility and supervision time is required from the informal caregiver.

Objective:

In order to minimize and reduce caregiver burden, it is important to explore its trajectory and the accompanying risk factors as dementia progresses; the objective of this systematic review.

Methods:

PRISMA guidelines were followed in this systematic review. Three databases, PubMed, PsycINFO, and EMbase, were systematically searched in November 2019 using specific keywords.

Results:

1,506 hits emerged during the systematic search but only eleven articles actually met the inclusion criteria for this review. The trajectory of caregiver burden is highly variable and depends on multiple factors. Important risk factors included: patients’ behavioral and neuropsychiatric symptoms, and their decline in functioning in (I)ADL; the caregiver’s age, gender, and physical and mental health; and, within the dyads (patient/caregiver), cohabitation and kinship.

Conclusion:

There is no one-size-fits-all for predicting how caregiver burden will change over time, but specific factors (like being a spouse and increased behavioral impairment and decline in functional status in the patient) may heighten the risk. Other factors, not yet comprehensively included in the published studies, might also prove to be important risk factors. Future research in the field of reducing caregiver burden is recommended to integrate the patient, caregiver, and context characteristics in the trajectory of caregiver burden, and to assess more clearly the phase of the dementia progression and use of external resources.

Assistive technology and telecare to maintain independent living at home for people with dementia: the ATTILA RCT

BACKGROUND

Assistive technology and telecare have been promoted to manage the risks associated with independent living for people with dementia, but there is limited evidence of their effectiveness.

OBJECTIVES

This trial aimed to establish whether or not assistive technology and telecare assessments and interventions extend the time that people with dementia can continue to live independently at home and whether or not they are cost-effective. Caregiver burden, the quality of life of caregivers and of people with dementia and whether or not assistive technology and telecare reduce safety risks were also investigated.

DESIGN

This was a pragmatic, randomised controlled trial. Blinding was not undertaken as it was not feasible to do so. All consenting participants were included in an intention-to-treat analysis.

SETTING

This trial was set in 12 councils in England with adult social services responsibilities.

PARTICIPANTS

Participants were people with dementia living in the community who had an identified need that might benefit from assistive technology and telecare.

INTERVENTIONS

Participants were randomly assigned to receive either assistive technology and telecare recommended by a health or social care professional to meet their assessed needs (a full assistive technology and telecare package) or a pendant alarm, non-monitored smoke and carbon monoxide detectors and a key safe (a basic assistive technology and telecare package).

MAIN OUTCOME MEASURES

The primary outcomes were time to admission to care and cost-effectiveness. Secondary outcomes assessed caregivers using the 10-item Center for Epidemiological Studies Depression Scale, the State-Trait Anxiety Inventory 6-item scale and the Zarit Burden Interview.

RESULTS

Of 495 participants, 248 were randomised to receive full assistive technology and telecare and 247 received the limited control. Comparing the assistive technology and telecare group with the control group, the hazard ratio for institutionalisation was 0.76 (95% confidence interval 0.58 to 1.01; p = 0.054). After adjusting for an imbalance in the baseline activities of daily living score between trial arms, the hazard ratio was 0.84 (95% confidence interval 0.63 to 1.12; p = 0.20). At 104 weeks, there were no significant differences between groups in health and social care resource use costs (intervention group - control group difference: mean -£909, 95% confidence interval -£5336 to £3345) or in societal costs (intervention group - control group difference: mean -£3545; 95% confidence interval -£13,914 to £6581). At 104 weeks, based on quality-adjusted life-years derived from the participant-rated EuroQol-5 Dimensions questionnaire, the intervention group had 0.105 (95% confidence interval -0.204 to -0.007) fewer quality-adjusted life-years than the control group. The number of quality-adjusted life-years derived from the proxy-rated EuroQol-5 Dimensions questionnaire did not differ between groups. Caregiver outcomes did not differ between groups over 24 weeks.

LIMITATIONS

Compliance with the assigned trial arm was variable, as was the quality of assistive technology and telecare needs assessments. Attrition from assessments led to data loss additional to that attributable to care home admission and censoring events.

CONCLUSIONS

A full package of assistive technology and telecare did not increase the length of time that participants with dementia remained in the community, and nor did it decrease caregiver burden, depression or anxiety, relative to a basic package of assistive technology and telecare. Use of the full assistive technology and telecare package did not increase participants' health and social care or societal costs. Quality-adjusted life-years based on participants' EuroQol-5 Dimensions questionnaire responses were reduced in the intervention group compared with the control group; groups did not differ in the number of quality-adjusted life-years based on the proxy-rated EuroQol-5 Dimensions questionnaire.

FUTURE WORK

Future work could examine whether or not improved assessment that is more personalised to an individual is beneficial.

Caffeine Consumption and Behavioral Symptoms in Nursing Home Residents: A Cross-Sectional Analysis

OBJECTIVE

Although behavioral changes are common in nursing home residents with dementia and caffeine is known to influence behavior in healthy adults, the effects of caffeine on the behavior of persons with dementia has received little attention. In this study we assessed the relationship of caffeine and behavioral symptoms in older persons with dementia.

DESIGN

A multicenter sub-cohort study embedded in the Elderly Care Physicians (ECP) training program.

SETTING

Dutch nursing homes associated with the ECP training program.

PARTICIPANTS

A total of 206 individuals with both diabetes and dementia resident in Dutch nursing homes.

MEASUREMENTS

Trainee ECPs collected data on caffeine consumption, cognition and behavioral symptoms using the NPI-NH, MDS-DRS and AES-C. Data on factors known to influence behavior in persons with dementia (e.g. marital status, kidney function, urinary tract infection and medication) were also collected.

RESULTS

Of the 206 participants, 70% showed behavioral symptoms. An increase in caffeine consumption was associated with a decrease in the presence of behavioral symptoms in the NPI-NH cluster affect and NPI-NH item agitation. Caffeine consumption groups also differed on the presence of disinhibition and depression. In addition, the severity of dementia influenced agitation, anxiety and the clusters affect and psychomotor.

CONCLUSION

In a large group of older persons with dementia resident in nursing homes, a low daily consumption of caffeine was associated with greater behavioral symptoms.

Biochemical Profiling and Elucidation of Biological Activities of Beta vulgaris L. Leaves and Roots Extracts

RESEARCH BACKGROUND

Red beet (Beta vulgaris L.) is commercially grown in Punjab and Khyber Pakhtunkhwa (KPK) regions while cultivated as vegetable in Baluchistan and Sindh regions of Pakistan. It is well known for its health-promoting role in several clinical and pathologic outcome due to abundance of betalains and other bioactive compounds. The purpose of study was to interpret bioactivity of of B. vulgaris leaves (BvLM) and roots (BvRM) extracts for finding natural cure of neurodegenerative diseases (NDs).

EXPERIMENTAL APPROACH

BvLM and BvRM extracts were evaluated for phytochemical composition, antioxidant, anti-inflammatory and anticholinesterase potential using standard protocols with modifications.

RESULTS

Phytochemicals analysis of BvLM and BvRM extracts depicted the presence of flavonoids, phenols, alkaloids, saponins and glycosides. The IC50 values for free radical scavenging activity for BvRM and BvLM showed that BvLM (DPPH: 2.20 ± 0.72 μg/mL,H 2 O 2 : 0.0519 ± 1.02 μg/mL) is more significant as compared to BvRM (DPPH: 2.312 ± 0.72 μg/mL,H 2 O 2 : 2.668 ± 0.49 μg/mL). BvLM showed significant protection against heat induced hemolysis of HRBCs and protein denaturation (2.322 ± 0.1 > 2.324 ± 0.06 μg/mL) as compared to BvRM (8.572 ± 0.2 > 50.18 ± 1.0 μg/mL). Both extracts found to exhibit strong inhibitory potential against acetylcholinesterase enzyme.

DISCUSSION/CONCLUSION

Our study highlighted B. vulagris extracts as rich and nutritious source of antioxidants, anti-inflammatory and cholinesterase inhibitors that could be helpful in preventing and treating neurodegenerative disorders (NDs). In consideration of multifactorial and complex etiology of NDs, BvLM and BvRM extracts would be apt candidates for development of therapeutic strategy for management of multiple cognitive disorders.

Protocol for a systematic review on the experience of informal caregivers for people with a moderate to advanced dementia within a domestic home setting

BACKGROUND

The knowledge about the experience of informal caregivers who provide care to people with moderate to advanced dementia in a domestic home setting is limited. A consequence of long hours of caregiving in addition to dealing with normal challenges of daily living is their experience of a poor quality of life. Some of their experiences may be described in terms of a feeling of powerlessness to make changes during care provision. This feeling may also suggest an experience of moral distress. The aim of this systematic review is to synthesise qualitative evidence relating to these experiences.

METHODS

This review adopts a narrative synthesis approach. A search will be conducted for studies written in the English language in the bibliographic databases MEDLINE Complete, CINAHL, EMBASE, PsycINFO, Web of Science and Academic Search Complete covering periods from 1984 to present. Included studies will be qualitative or mixed-methods designs. The search terms will be related to dementia and caregivers, and the process will be focused on dementia at the moderate to the advanced stages within the domestic home setting. Reference lists of included papers will also be searched for additional relevant citations. Search terms and strategies will be checked by two independent reviewers. The identification of abstracts and full texts of studies will be done by the author, while the quality and the risk of bias will also be checked by the two independent reviewers.

DISCUSSION

Psychological distress is cited as an experience reported within informal caregiving. For the caregiver, it is associated with a negative impact on general health. To date, no synthesis exists on the specific experience of informal caregiving for people with moderate to advanced dementia within the domestic home setting. This review considers that variation of accounts contributes to how the informal caregivers' general experience is explored in future research. This may enable gaps in current knowledge to be highlighted within the wider context of caregiving in the domestic home setting.

SYSTEMATIC REVIEW REGISTRATION

This review is registered with PROSPERO ( CRD42020183649 ).

The impact of assistive technology on burden and psychological well-being in informal caregivers of people with dementia (ATTILA Study)

INTRODUCTION

Assistive technology and telecare (ATT) may alleviate psychological burden in informal caregivers of people with dementia. This study assessed the impact of ATT on informal caregivers' burden and psychological well-being.

METHODS

Individuals with dementia and their informal caregivers were recruited to a randomized-controlled trial assessing effectiveness of ATT. Caregivers were allocated to two groups according to their cared-for person's randomization to a full or basic package of ATT and were assessed on caregiver burden, state anxiety, and depression. Caregivers' data from three assessments over 6 months of the trial were analyzed.

RESULTS

No significant between- or within-group differences at any time point on caregivers' burden, anxiety, and depression levels were found.

DISCUSSION

Full ATT for people with dementia did not impact caregivers' psychological outcomes compared to basic ATT. The length of follow up was restricted to 6 months.

Tip of the Iceberg: Assessing the Global Socioeconomic Costs of Alzheimer's Disease and Related Dementias and Strategic Implications for Stakeholders

While it is generally understood that Alzheimer’s disease (AD) and related dementias (ADRD) is one of the costliest diseases to society, there is widespread concern that researchers and policymakers are not comprehensively capturing and describing the full scope and magnitude of the socioeconomic burden of ADRD. This review aimed to 1) catalogue the different types of AD-related socioeconomic costs described in the literature; 2) assess the challenges and gaps of existing approaches to measuring these costs; and 3) analyze and discuss the implications for stakeholders including policymakers, healthcare systems, associations, advocacy groups, clinicians, and researchers looking to improve the ability to generate reliable data that can guide evidence-based decision making. A centrally emergent theme from this review is that it is challenging to gauge the true value of policies, programs, or interventions in the ADRD arena given the long-term, progressive nature of the disease, its insidious socioeconomic impact beyond the patient and the formal healthcare system, and the complexities and current deficiencies (in measures and real-world data) in accurately calculating the full costs to society. There is therefore an urgent need for all stakeholders to establish a common understanding of the challenges in evaluating the full cost of ADRD and define approaches that allow us to measure these costs more accurately, with a view to prioritizing evidence-based solutions to mitigate this looming public health crisis.

Blessings or burdens: an Interpretative Phenomenological Analysis (IPA) study on the motivations and their impact on end-of-life caregiving among Asian family caregivers

BACKGROUND

While the impact of family caregiving has been well-documented, many of such studies center on investigating external factors such as socioeconomic status, accessibility to resources and availability of social support as the primary causation of caregiver wellbeing outcomes. This paper explores the motivations that drive family caregivers in supporting their family members at the end-of-life, and critically examines how internal appraisal processes of such motivations can both positively and negatively impact their wellbeing.

METHODS

This study adopted an interpretative phenomenological analysis (IPA) to investigate the motivations and internal appraisal processes of Asian family caregivers in Singapore who were tending to a dying family member. Qualitative dyadic interview data (N = 20) was drawn from a larger Randomized Controlled Trial for a novel Family Dignity Intervention (FDI) for palliative care patients and their families. The sampling population consisted of participants aged 21 and above who were identified to be the primary caregivers of older palliative care patients with a prognosis of less than 12 months. Data collection was conducted in the homes of patients and family caregivers.

RESULTS

Findings revealed six themes that could either nurture or diminish caregiver wellbeing: 1) Honoring Fidelity (caregivers were motivated to commit to their caregiving roles in order to avoid regret), 2) Alleviating Suffering (caregivers were motivated to relieve their family member's pain), 3) Enduring Attachment (caregivers were motivated to spend time together with their family member), 4) Preserving Gratitude (caregivers were motivated to express their appreciation to their family member by caregiving), 5) Navigating Change (caregivers were motivated to adapt accordingly to changes in the illness trajectory) and 6) Reconciling with Mortality (caregivers were motivated to respond accordingly to their family member's prognosis). The final theme of the Wellbeing Determinant is posited as an indication of self-determination, and is conjectured to influence how caregiving motivations are appraised by the caregiver.

CONCLUSION

Fulfilling and enhancing one's sense of self-determination appears central to infusing one's caregiving motivations with positive meaning, and consequently nurturing one's wellbeing in the end-of-life caregiving journey. These findings are discussed with recommendations for healthcare professionals working with family caregivers of palliative care patients.

Propiedades psicométricas de una escala de resiliencia en cuidadores familiares de adultos mayores

El cuidado de un adulto mayor se ha estudiado no solo como una circunstancia generadora de estrés y deterioro del bienestar para el cuidador, sino también, desde la perspectiva de la psicología positiva, como la disposición de los cuidadores para reaccionar de manera resiliente ante las dificultades experimentadas. El objetivo del presente estudio fue realizar la validación de constructo del Inventario de Resiliencia (IRES) mediante algunos procedimientos exploratorios y confirmatorios. Para ello, se colectaron datos de dos muestras independientes de cuidadores familiares de adultos mayores en la ciudad de Hermosillo, México: la primera con 125 cuidadores de 19 a 73 años (Medad = 47.8, DE = 12) para los análisis factoriales exploratorios; y la segunda con 160 cuidadores de 19 a 82 años (Medad = 48.7, DE = 13) para los análisis factoriales confirmatorios. Los análisis revelaron dos dimensiones claras y robustas estadísticamente en el IRES con 12 ítems: la resiliencia instrumental y la resiliencia emocional. En conclusión, la presente investigación muestra que el IRES es un instrumento válido para la medición de la resiliencia en una población mexicana de cuidadores familiares de adultos mayores.

The effects of bibliotherapy on the mental well-being of informal caregivers of people with neurocognitive disorder: A systematic review and meta-analysis

BACKGROUND

The number of people with neurocognitive disorder is increasing, and the majority of them are cared for by informal caregivers in the community. Mental health problems are common among caregivers, however, professional support for them is often limited. Non-pharmacological self-help interventions, such as bibliotherapy, may improve mental well-being and has the potential for being integrated into clinical or social services.

OBJECTIVES

To explore what types of bibliotherapy have been used for improving the mental well-being of informal caregivers of people with neurocognitive disorders, and the effect on mental well-being outcomes.

DESIGN

A systematic review and meta-analysis.

REVIEW METHODS

Six databases were searched for relevant articles on July 1, 2019. Clinical trial registries and the reference lists of included studies were also searched. Both randomized controlled trials and quasi-experimental studies were included. The Cochrane Collaboration risk of bias tool for randomized controlled trials was used to assess the quality of studies. Review Manager 5.3 was used to analyze data, standardized mean difference (SMD) and 95% confidence interval (CI) were used to estimate the pooled treatment effect. Random effects models were used for meta-analyses. Funnel plot was not performed due to the limited number of studies. This systematic review was registered at PROSPERO (CRD42019129152).

RESULTS

Nine randomized controlled trials with 1036 informal caregivers were included. Most of the included studies had some aspects of bias. Three types of bibliotherapy were used. Bibliotherapy had a significant pooled medium to large effect on reducing depression at Z = 1.99 (SMD = -0.74, 95%CI = -1.47 to -0.01, p = .05), however, the heterogeneity was high (I² = 94%). For the subgroups, only the video-based bibliotherapy significantly reduced depression at Z = 2.78 (I² = 83%, SMD = -2.11, 95%CI = -3.6 to -0.62, p = .005). Bibliotherapy had a significant small to medium effect on caregiver's self-efficacy for dealing with problem behaviours at Z = 2.44 (I² = 0, SMD = 0.36, 95%CI = 0.05 to 0.67, p = .02), however, the effect on self-efficacy for obtaining respite was not significant (I² = 0, SMD =  0.17, 95%CI = -0.16 to 0.49, p = .32). The effect on decreasing state anxiety was significant at Z = 2.30 (I² = 22%, SMD = -0.22, 95% CI = -0.41 to -0.33, p = .02).

CONCLUSIONS

Bibliotherapy showed positive effects on reducing depression, improving self-efficacy for dealing with problem behaviors and reducing anxiety among informal caregivers. The effects on reducing depression should be viewed with caution due to high heterogeneity. The effects on other mental well-being outcomes are inconclusive due to limited number of studies and this underscores the need for further research.

Anxiety in Informal Dementia Carers: A Meta-Analysis of Prevalence

Much of the carer literature has focused on depression and burden as primary outcomes and anxiety appear somewhat neglected. Providing evidence on the prevalence of carer anxiety is critical as it can enhance awareness among professionals, which in turn can lead to improved access to efficacious treatments. This meta-analysis updated the previous review conducted in 2007 to estimate the up-to-date prevalence of anxiety in informal carers for people with dementia. Literature searches were conducted in databases of published and unpublished literature. Events and sample size data were pooled using a random effects model to obtain an overall prevalence percentage. A total of 10 studies were included, resulting in a pooled estimate of anxiety prevalence at 32.1% (95% confidence interval: 20.6%-46.2%, P = .01). Significant heterogeneity was found, which was not reduced following sensitivity analysis. This study suggests anxiety is a prevalent difficulty experienced by dementia carers. Additional research recommendations and clinical implications are discussed.

Electronic cigarette use and psychological distress in the Native Hawaiian and Pacific Islander adults compared with other racial/ethnic groups: Data from the National Health Interview Survey, 2014

Document the prevalence of electronic cigarette (E-cigarette) use among the native Hawaiian and other Pacific Islander (NHPI) adults compared with other racial/ethnic groups, and examine associations between psychological distress and E-cigarette use. 2014 National Health Interview Survey (NHIS) and 2014 NHPI-NHIS were combined for comparisons. Data were analyzed using descriptive statistics, Rao-Scott χ2 test, and multivariable logistic regression. E-cigarette use among NHPI (5.6%) was significantly higher than among Blacks (2.1%), Hispanics (2.2%), and Asians (1.7%; p < .001). NHPI with Kessler 6 (K6) score of 11-24 had greater odds of using E-cigarettes (odds ratio [OR]: 3.90; 95% confidence intervals [CI]: 1.81-8.42) as compared to those with a K6 score of 0. Associations between having a K6 score of 11-24 and using E-cigarettes were also found for Whites (OR: 3.49; CI: 2.44-4.99), Asians (OR: 5.29; CI: 1.29-21.70), and Hispanics (OR: 6.14; CI: 2.72-13.83). E-cigarette use was higher among NHPI relative to other racial/ethnic groups. NHPI with K6 score of 11-24 had greater odds of using E-cigarettes as compared to those with a K6 score of 0. Policies and strategies to reduce E-cigarette use among NHPI should give careful consideration to the associations between E-cigarette use and psychological distress in the NHPI population.

Exploring the usefulness of indicators for referring people with dementia and their informal caregivers to activating interventions: a qualitative analysis of needs assessments

Background

People with dementia (PWDs) and their informal caregivers frequently report difficulties in maintaining their usual activities. We had previously developed a set of indicators to estimate whether dyadic, activating interventions can meet these needs for activity. This study investigates how PWDs and informal caregivers talk about the indicators in interviews for needs assessments, and how professionals identify activity needs and preferences. Our research goal was to explore the usefulness of the indicators for assessing the activity needs of community-dwelling dyads. Such assessments are needed for appropriate referral to activating interventions.

Methods

A dementia case manager assessed the needs of community-dwelling PWDs and their informal caregivers; we carried out secondary analyses on the dataset resulting from the audio-tapes and transcripts. We applied qualitative, deductive content analysis because we wanted to identify both explicit and implicit needs and preferences. We used the indicators that we had developed in previous research as codes.

Results

Both PWDs and informal caregivers do explicitly mention needs, preferences, and characteristics related to the indicators in the needs assessments. Possible implicit needs and preferences were frequently identified in their stories.

Conclusions

Needs-driven care requires high-quality needs assessments. Both PWDs and their informal caregivers need encouragement to express their latent needs and preferences. In addition, latent needs and preferences have to be further explored in needs assessments to find out the real meaning. The outcomes of this study highlight the significance of structured needs assessments for mapping the activity needs of PWDs and their informal caregivers. Many PWDs and informal caregivers reported activity needs, which suggests that activating interventions may be appropriate. The indicators can help professionals identify activity needs so that they can discuss matching activating interventions with the dyad.

The course of neuropsychiatric symptoms in patients with dementia in primary care

BACKGROUND

During the course of dementia, most people develop some type of neuropsychiatric symptoms (NPS), which result in lower quality of life, high caregiver burden, psychotropic drug use and a major risk of institutionalization. Studies on NPS in people with dementia have been mainly conducted in clinical centres or psychiatric services.

OBJECTIVES

To investigate the course of NPS in people with dementia in primary care.

METHODS

Analysis of (cumulative) prevalence and incidence, persistence and resolution based on data collected during an assessment at home of a prospective naturalistic cohort study in primary care in a sample of 117 people with dementia and their informal caregivers. Subsyndromes of NPS were assessed with the Neuropsychiatric Inventory (NPI) and Cohen-Mansfield Agitation Inventory. Multivariate analyses were used to detect determinants for the course of NPS.

RESULTS

The mean age of the people with dementia was 78.6 years, and 52% were female. Mean Mini-Mental State Examination total score was 19.5, mean NPI total score 15.7. The most prevalent clinically relevant subsyndromes of the NPI were hyperactivity and mood/apathy, and the most prevalent individual NPS were aberrant motor behaviour (28%), agitation/aggression (24%) and apathy/indifference (22%). Of the people with dementia, 72.3% had one or more symptoms of the mood/apathy and 75.3% of the hyperactivity subsyndrome.

CONCLUSIONS

GPs should be aware of NPS in people with dementia and should actively identify them when they visit these patients or when informal caregivers consult them. Timely diagnosing facilitates adequate professional care.

Prevalence of depression and burden among informal care-givers of people with dementia: a meta-analysis

This meta-analysis examined the prevalence of depression and burden among informal care-givers of people with dementia (PwD) and compared the prevalence of depression between male and female, and spousal and non-spousal, care-givers. The quality of studies was evaluated and moderator variables explored. A search of six electronic databases (PsycARTICLES, PsycINFO, MEDLINE Complete, SCOPUS, Web of Science and ProQuest) was conducted from the first available date to the 31 October 2017. Inclusion criteria involved observational studies on the prevalence of burden or depression among informal care-givers of PwD. Forty-three studies were examined with a total of 16,911 participants. The adjusted pooled prevalence of depression was 31.24 per cent (95% confidence interval (CI) = 27.70, 35.01) and burden was 49.26 per cent (95% CI = 37.15, 61.46), although heterogeneity among prevalence estimates was high. Depression prevalence estimates differed according to the instrument used and the continent where the study was conducted. The odds of having depression were almost one and a half times higher in female compared to male care-givers. No significant difference was observed between spouses and non-spouses. Most studies had a medium risk of bias. Results suggest a great need within this population for interventions that are effective at reducing burden and depressive symptoms. It therefore appears imperative for dementia services that are not providing such interventions to do so.

Factors related to sense of competence in family caregivers of people living with dementia in the community: a narrative synthesis

ABSTRACTObjectives:Sense of competence defines a caregiver's feeling of being capable to manage the caregiving task and is an important clinical concept in the caregiving literature. The aim of this review was to identify the factors, both positive and negative, associated with a caregiver's perception of their sense of competence.

DESIGN

A systematic review of the literature was conducted, retrieving both quantitative and qualitative papers from databases PsycINFO, CINAHL, EMBASE, and Medline. A quality assessment was conducted using the STROBE and CASP checklists, and the quality rating informed the inclusion of papers ensuring the evidence was robust. Narrative synthesis was employed to synthesize the findings and to generate an updated conceptual model of sense of competence.

RESULTS

Seventeen papers were included in the review, all of which were moderate to high quality. These included 13 quantitative, three mixed-methods and one qualitative study. Factors associated with sense of competence included: behavioral and psychological symptoms of dementia (BPSD), caregiver depression, gratitude, and the ability to find meaning in caregiving.

CONCLUSIONS

The results of this review demonstrate that both positive and negative aspects of caring are associated with caregiver sense of competence. Positive and negative aspects of caregiving act in tandem to influence caregiver perception of their competence. The proposed model of sense of competence aims to guide future research and clinical interventions aimed at improving this domain but requires further testing, as due to the observational nature of the include papers, the direction of causality could not be inferred.

Caffeine and neuropsychiatric symptoms in patients with dementia: A systematic review

BACKGROUND

The consumption of caffeine has well known effects on the behavior and sleep of healthy adults. Behavioral symptoms and sleeping difficulties are common in patients with dementia which may be affected by caffeine consumption. This systematic review examines the association between caffeine intake and neuropsychiatric symptoms in patients with dementia.

METHODS

In January 2019 an extensive search was conducted in Medline (PubMed), Embase, Emcare, Cochrane, PsychInfo, Web of Science and gray literature. Studies were included when they: i) investigated patients diagnosed with dementia, ii) reported neuropsychiatric symptoms, iii) used caffeine or coffee consumption as an intervention, and iv) reported associations between caffeine or coffee consumption and neuropsychiatric symptoms. Studies were excluded when they also included participants without a diagnosis of dementia, or presented a review or expert opinion. Two reviewers independently rated the studies and reached consensus on the appraisal.

RESULTS

Of the seven studies eligible for this review, four reported on sleeping difficulties and five on behavioral symptoms. There was no consistent effect of caffeine administration on neuropsychiatric symptoms: e.g., both high caffeine consumption and eliminating caffeine were associated with less apathy, the total Neuropsychiatric Inventory (Nursing Home) decreased after both coffee therapy and after eliminating caffeine, and both caffeine consumption and eliminating caffeine improved sleep.

CONCLUSION

These findings suggest that caffeine can either induce or reduce neuropsychiatric symptoms in individual patients with dementia. Therefore, in these patients, caffeine consumption requires a prudent individualized approach and further research on the effects of caffeine on individual neuropsychiatric symptoms is required.

Exploring stress, coping, and decision-making considerations of Alzheimer's family caregivers

More than 15 million Americans are providing care for a family member with Alzheimer's disease. Family caregivers are faced with highly stressful experiences, using strong coping skills, and implementing critical decisions with little or no knowledge or information and with virtually no preparation or assistance. The need for research efforts to focus on caregiver stress, coping mechanisms, and informed decision-making skills spearheaded a theoretical framework to study the potential relationships between family caregivers' types of stress, coping skills, and their decision-making efforts. Constructs of life event stress, role strain, self-concept stress, and coping stress were examined relative to 10 priority areas of decision-making identified by the national Alzheimer's Association. A relational non-experimental research design was utilized. Caregivers completed four Likert-scale instruments with data analyzed using descriptive statistics and rank-order correlation procedures. Findings indicated varying levels of stress, strong family self-efficacy and high levels of coping skills contribute to critical decision-making.

A virtual reality intervention to improve the understanding and empathy for people with dementia in informal caregivers: results of a pilot study

OBJECTIVE

Informal caregivers often experience psychological distress due to the changing functioning of the person with dementia they care for. Improved understanding of the person with dementia reduces psychological distress. To enhance understanding and empathy in caregivers, an innovative technology virtual reality intervention Through the D'mentia Lens (TDL) was developed to experience dementia, consisting of a virtual reality simulation movie and e-course. A pilot study of TDL was conducted.

METHODS

A pre-test-post-test design was used. Informal caregivers filled out questionnaires assessing person-centeredness, empathy, perceived pressure from informal care, perceived competence and quality of the relationship. At post-test, additional questions about TDL's feasibility were asked.

RESULTS

Thirty-five caregivers completed the pre-test and post-test. Most participants were satisfied with TDL and stated that TDL gave more insight in the perception of the person with dementia. The simulation movie was graded 8.03 out of 10 and the e-course 7.66. Participants significantly improved in empathy, confidence in caring for the person with dementia, and positive interactions with the person with dementia.

CONCLUSION

TDL is feasible for informal caregivers and seems to lead to understanding of and insight in the experience of people with dementia. Therefore, TDL could support informal caregivers in their caregiving role.

In Vitro Anti-Cholinesterase and Antioxidant Activity of Extracts of Moringa oleifera Plants from Rivers State, Niger Delta, Nigeria

This study evaluated Moringa oleifera extracts from two locations in Niger Delta for in vitro anti-cholinesterase and antioxidant activities. Methanolic, aqueous and ethanolic extracts of Moringa oleifera were evaluated for inhibition of acetylcholinesterase (AChE) activity, antioxidant properties, and total phenolic and flavonoid contents using standard procedures. M. oleifera extracts possessed significant and concentration dependent AChE inhibitory activity for methanolic, aqueous, and ethanolic extracts. For the most potent extracts, the percentage AChE inhibition/IC₅₀ (µg/mL) values were Moringa oleifera root methanolic extracts (MORME): ~80%/0.00845; Moringa oleifera root ethanolic extract 1 (MOREE1): ~90%/0.0563; Moringa oleifera root ethanolic extract 2 (MOREE2): ~70%/0.00175; and Moringa oleifera bark ethanolic extract (MOBEE): ~70%/0.0173. The descending order of AChE inhibitory potency of plant parts were: root > bark > leaf > flowers > seed. All M. oleifera methanolic extracts at a concentration of 1000 µg/mL displayed significant (p < 0.05–0.001) DPPH radical scavenging activity, with values of ~20–50% of that of ascorbic acid. The total phenolic content and total flavonoid content (TPC/TFC) of MORME, Moringa Oju bark methanolic extract (MOBME), MOREE1, MOREE2 and Moringa leaf ethanolic leaf extract (MLEE) were (287/254), (212/113), (223/185), (203/343) and (201/102) mg gallic acid equivalents/g and quercetin equivalents/g, respectively. There was an inverse correlation between plant extract AChE inhibition and total phenolic (p < 0.0001) and total flavonoid contents (p < 0.0012). In summary, this study revealed 5 of 19 extracts of M. oleifera that have potent in vitro anti-cholinesterase and antioxidant activities.

The influence of the individual neuropsychiatric symptoms of people with Alzheimer disease on family caregiver distress-A longitudinal ALSOVA study

OBJECTIVES

Family caregivers (FCs) face a variety of demands while caring for persons with Alzheimer disease (AD). Longitudinal studies identifying the specific AD-related neuropsychiatric symptoms (NPS) that contribute to FC distress are rare. We analyzed which NPS in association with care recipient and caregiver demographic factors are associated with FC psychological distress over a 36-month follow-up period.

DESIGN

This is a longitudinal study with annual follow-up. Participants were people with AD (n = 226) and their FCs (n = 226).

MEASUREMENTS

The Neuropsychiatric Inventory was used to assess NPS, and The General Health Questionnaire was used as a measure of caregiver distress. The effect of NPS on FC psychological distress over time was analyzed using a linear-mixed effect model.

RESULTS

Delusions (P = .003), agitation (P < .001), and sleep disturbance (P = .005) are associated with FC psychological distress. One of four people with AD developed delusions and agitation during the early stages of the disease. Sleep disturbances increased over the follow-up time. A marital relationship was associated with FC distress, while some prevalent symptoms, such as depression, did not affect distress.

CONCLUSIONS

Delusions, agitation, and sleep disturbances may cause distress to the FCs of persons with AD, especially if they live together. Clinicians should meet with FCs regularly and recognize those FCs at risk for a decline in psychosocial health.

Resilience and burden in caregivers of older adults: moderating and mediating effects of perceived social support

BACKGROUND

The burden of caring for an older adult can be a form of stress and influence caregivers' daily lives and health. Previous studies have reported that resilience and social support play an important role in reducing physical and psychological burden in caregivers. Thus, the present study aimed to examine whether perceived social support served as a possible protective factor of burden among caregivers of older adults in Singapore using moderation and mediation effects' models.

METHODS

We conducted a cross-sectional study with 285 caregivers providing care to older adults aged 60 years and above who were diagnosed with physical and/or mental illness in Singapore. The Connor-Davidson Resilience Scale (CD-RISC) was used to measure resilience and burden was measured by the Zarit Burden Interview (ZBI). The Multidimensional Scale of Perceived Social Support (MSPSS) was used to measure perceived social support. Hayes' PROCESS macro was used to test moderation and mediation effects of perceived social support in the relationship between resilience and burden after controlling for sociodemographic variables. Indirect effects were tested using bootstrapped confidence intervals (CI).

RESULTS

The mean scores observed were CD-RISC: 70.8/100 (SD = 15.1), MSPSS: 62.2/84 (SD = 12.2), and ZBI: 23.2/88 (SD = 16.0) respectively. While perceived social support served as a full mediator between resilience and caregiver burden (β = - 0.14, 95% CI -0.224 to - 0.072, p < 0.05), it did not show a significant moderating effect.

CONCLUSIONS

Perceived social support mediates the association between resilience and caregiver burden among caregivers of older adults in Singapore. It is crucial for healthcare professionals, particularly those who interact and deliver services to assist caregivers, to promote and identify supportive family and friends' network that may help to address caregiver burden.

Neuropsychiatric symptoms and psychotropic drug use in patients with dementia in general practices

BACKGROUND

Neuropsychiatric symptoms (NPS) frequently occur in community-dwelling patients with dementia and they are also frequently prescribed psychotropic drugs. The prescription of psychotropic drugs has been found to be associated with the level of NPS. Data on NPS in patients with dementia in general practices are scarce.

OBJECTIVES

The aim of this study was to assess the prevalence rates of NPS and psychotropic drug use (PDU) in patients with dementia in general practices.

METHODS

We analyzed data from the baseline measurement of a prospective cohort study in a sample of (Dutch) patients in general practices. Prevalence rates of NPS and subsyndromes assessed with the Neuropsychiatric Inventory (NPI) and of PDU were calculated. Prevalence rates of individual NPS are presented both as clinically relevant symptoms (NPI symptom score ≥ 4) and as prevalence rates of symptoms with symptom score > 0.

RESULTS

Of the 117 patients, more than 90% had at least one symptom and more than 65% had at least one clinically relevant symptom. The most common NPS were agitation/aggression, dysphoria/depression and irritability/lability. The most common clinically relevant NPS were aberrant motor behaviour, agitation/aggression and apathy/indifference. Only 28.7% of the patients used at least one, 7.0% used at least two different and 1.7% used at least three different types of psychotropic drugs (excluding anti-dementia medication).

CONCLUSIONS

NPS are highly prevalent in patients with dementia in general practices, but PDU is rather low. The most common clinically relevant NPS were aberrant motor behaviour, agitation/aggression and apathy/indifference.

The Impact of Dementia on Family Caregivers: What Is Research Teaching Us?

Dementia family caregiving has been the focus of research for decades. Much has been learned about the negative impact of caregiving as well as characteristics that may be protective. This paper explores themes in caregiving pertinent to clinicians and researchers working with dementia family caregivers: the psychological, subjective, and physical outcomes of caregiving, ways in which dementia alters relationships between the patient and caregiver, and strategies for improving outcomes for caregivers. Suggestions for next steps in research and clinical care are made.

Voices of Spouses Living with Partners with Neuropsychiatric Symptoms Related to Dementia

Persons with dementia, who reside in their own homes, are often cared for by family members. The presence of a family career is said to have a protective effect, postponing admissions to residential care. The majority of persons with dementia develop behavioural and personality changes during the disease trajectory also known as neuropsychiatric symptoms. Quality of life for both the person with neuropsychiatric symptoms and their careers are affected, increasing suffering and risk for hospitalisation and admission to long-term residential care. Family careers to persons with dementia have identified behavioural changes as more distressing than cognitive impairment leading to increased burden of care and admissions to residential care. Knowledge gaps exist regarding how family careers living with persons with dementia experience neuropsychiatric symptoms in a community setting. The aim was to describe spouses' experiences of living with partners who have developed neuropsychiatric symptoms related to dementia in a community setting. Semi-structured interviews were carried out with 14 spouses of partners with dementia. The interviews included completion of the neuropsychiatric inventory. Interview data were analysed using a content analysis approach. The results showed that spouses identified in the neuropsychiatric inventory that partners with dementia had on average five to eight co-existing symptoms. Frequency, severity and distress varied. From the narrative data, the theme living on the edge lacking support and time for self, emerged. The findings of this study suggest that support offered to persons with dementia and their spouses should have a person-centred approach meeting individual needs. Safety and welfare of persons with dementia and their spouses residing in their own homes may be jeopardised in the presence of neuropsychiatric symptoms. A greater awareness is required in the community regarding the well-being of these persons.

Coping strategies and psychological distress in caregivers of patients with Amyotrophic Lateral Sclerosis (ALS)

BACKGROUND

Amyotrophic lateral sclerosis (ALS) causes distress in caregivers. The present study aims to examine the association between coping strategies and psychological distress in caregivers of ALS patients.

METHODS

Coping strategies were assessed in 96 ALS informal caregivers by means of the Coping Inventory for Stressful Situations. Data about caregivers' demographic characteristics, levels of burden, depression and anxiety (psychological distress) were also gathered by standardised questionnaires. Patients' clinical, cognitive and behavioural disturbances were evaluated by ALS specific assessment tools.

RESULTS

Sequential logistic regression analysis showed that emotion-oriented coping strategy was significantly associated with high levels of depressive (p < 0.01) and anxiety (p < 0.05) symptoms and high levels of burden (p < 0.05), after controlling for all other variables. Moreover, a significant relationship of patients' functional dependence levels with burden experienced by caregivers was observed. No relationships were detected between task-oriented and avoidance-oriented coping strategies and caregivers' levels of psychological distress.

CONCLUSIONS

The present study supported the mediating effects of coping strategies on intensity of burden, depression and anxiety experienced by ALS caregivers. These findings suggest that interventions aimed at reducing utilisation of maladaptive coping strategies may improve well-being in ALS caregivers, and, possibly, management of symptoms in ALS patients.
