Telephone-based behavioral activation intervention for dementia family caregivers: Outcomes and mediation effect of a randomized controlled trial

Positive dementia caregiving in 30 days (PDC30): Study protocol of a randomized controlled trial of a self-guided automated online training program

The Benefit-Finding Intervention, a face-to-face psychoeducation program with a focus on the positive meanings of caregiving, has been found to reduce depressive symptoms and burden in dementia caregivers. The program was revamped into a computer-delivered web-based program to enable 24/7 access without location restriction. This study evaluates the efficacy of this new online program called Positive Dementia Caregiving in 30 Days (PDC30). A 2-arm (PDC30 vs. waitlist control) parallel-group randomized controlled trial will be conducted. Target sample is 200 mildly depressed dementia family caregivers with internet access and fluency in English, who will be recruited globally through a YouTube video promoted on social media and through service agencies. The primary outcome is depressive symptoms whereas secondary outcomes are anxiety symptoms, burden, and positive gains, all collected at baseline and 1, 2, and 3 months. The treatment x time (both linear and quadratic) interaction effects will be examined using mixed-effect regression. Additionally, possible therapeutic mechanisms via strengthened self-efficacy in controlling upsetting thoughts and positive reappraisal coping will be examined in a mediation path model. If positive treatment effects are found, the potential public health benefits, given the ease of access, universal availability, and flexible approach, of this online intervention are considerable.

Effectiveness of Technology-Delivered Psychosocial Interventions for Family Caregivers of Patients With Dementia: A Systematic Review, Meta-Analysis and Meta-Regression

Family caregivers living with patients with dementia (PwD) face psychological challenges due to care burden. Technology-delivered psychosocial interventions (TPIs) have played a promising role in improving health outcomes among family caregivers living with PwD. This review aims to synthesise evidence of the effectiveness of TPIs on primary (burden and depression) and secondary outcomes (self-efficacy, stress and anxiety) for family caregivers living with PwD. Random-effects meta-analyses were performed to determine effect size. Using Cochran's Q and I2 tests, statistical heterogeneity was evaluated. Sensitivity, subgroup analyses and meta-regression were employed to explain statistical heterogeneity. Twenty-eight trials comprising 4160 family caregivers from eight countries were included. Our meta-analysis revealed that TPIs resulted in slight reduction in depression, probably resulted in a slight reduction in burden and anxiety and slight increase in self-efficacy. Subgroup differences were detected in geographical regions (Western Pacific and Southeast Asia) for burden. While there were no significant subgroup differences in other factors, TPIs with preventive function and mobile applications had a more prominent larger effect size. Meta-regression analysis showed that attrition rate was a significant moderator on depression. Results are limited by the high risk of bias of included trials, which may reduce certainty of evidence. This review suggest TPIs are recommended as an adjunct treatment for alleviating burden and depressive outcomes in healthcare institutions. PROSPERO Registration Number: PROSPERO (CRD42023387962).

Impacts and Pathways of Behavioral Activation on Psychological Distress Among Patients Diagnosed With Esophageal and Gastric Cancer in China: A Randomized Controlled Trial

OBJECTIVE

The objective of this study is to investigate the efficacy of behavioral activation (BA), a novel psychological intervention, in ameliorating psychological distress and anxiety symptoms among patients diagnosed with esophageal and gastric cancer, as well as the mediating role of self-efficacy between BA and psychological distress.

METHODS

A total of 139 patients diagnosed with esophageal and gastric cancer were recruited in China from March 2023 to October 2023 and randomly assigned to either the BA plus care as usual group (BA+CAU group) or the care as usual group (CAU group). Pre- and post-intervention questionnaires, including the Psychological Distress Thermometer (DT), Generalized anxiety disorder 7-item (GAD-7) Scale, General Self-Efficacy Scale (GSES) and the activation subscale of Behavioral Activation for Depression Scale (BADS-A), were administered.

RESULTS

Generalized estimating equation analyses revealed that, compared to usual care alone, combining BA with usual care significantly ameliorated psychological distress, anxiety as well as improved self-efficacy and activation. The mediation analysis revealed that self-efficacy served as a mediator in the relationship between activation and psychological distress.

CONCLUSIONS

BA primarily based on telephone or WeChat can not only directly ameliorates psychological distress and anxiety symptoms in patients with esophageal cancer and gastric cancer but also indirectly alleviates psychological distress by enhancing self-efficacy. The study also demonstrates the potential of BA in cancer patients, a skill that can be effectively acquired by primary care workers without specialized training and implemented more flexible.

A Randomized Controlled Trial of a Behavioral Activation Intervention to Increase Engagement with Life and Well-Being in Older Adults

INTRODUCTION

Engagement with life is central to aging well. There is currently a lack of flexible programs for promoting engagement that tailor to the unique interests, capacities, and life circumstances of individuals. We designed and evaluated a new program for promoting engagement with later life based on principles of behavioral activation.

METHODS

A total of 135 adults aged 65 years and older who scored at or below the median on the Life Engagement Test were randomly assigned to either a 6-week behavioral activation program (n = 69) or a 6-week well-being program based on brief positive psychology interventions (the active control; n = 66). Participants completed assessments at baseline, 1-week follow-up, and 3-month follow-up. The primary outcome was engagement with life, and secondary outcome measures included social network characteristics, measures of mental health, well-being, and psychological and self-regulatory resources.

RESULTS

Participants in both conditions showed improvements in engagement with life post-intervention that were sustained at 3 months. Post-intervention improvements in both conditions were observed across most secondary outcomes; however, for several outcomes, participants with more limited functional and cognitive resources benefitted from participation in the positive psychology (active control) condition, but not the treatment condition.

CONCLUSION

Similar levels of improvement in engagement with life and well-being were evident for participants who completed a behavioral activation-focused intervention, compared with participants who completed a positive psychology-focused intervention. The positive psychology approach may confer greater benefits for emotional well-being among those with poorer functional and cognitive abilities.

A meta-analysis of mindfulness-based interventions for improving mental health and burden among caregivers of persons living with dementia

BACKGROUND

Mindfulness-based interventions are becoming increasingly popular and are effective in lowering depressive symptoms and caregiver burden. However, the overall efficacy of therapies in stress and anxiety management is unreported, and no study to date has performed a subgroup analysis to investigate the intervention dose response of outcomes.

AIMS

To quantitatively identify the effectiveness of mindfulness-based interventions for caregivers of persons living with dementia.

METHODS

A comprehensive literature search of six databases was undertaken from the date of inception to June 18, 2023. The DerSimonian-Laird model with random effects was used to examine the overall effect and its heterogeneity in the studies. Version 2 of the risk of bias (RoB 2) tool was employed to analyze the publication bias of each randomized study. Funnel and forest plots were created to represent the findings.

RESULTS

Thirteen randomized trials were included in the meta-analysis. Mindfulness-based interventions significantly reduced stress and anxiety of caregivers of persons living with dementia. In addition, interventions provided for ≥8 weeks were beneficial in reducing depression in caregivers. However, mindfulness-based interventions did not offer significant benefits in reducing depression or caregiver burden immediately after the intervention.

CONCLUSION

Mindfulness-based interventions have the potential to help caregivers of people living with dementia. This study could be used as a model for future research into and implementation of mindfulness-based therapies for caregivers.

LINKING EVIDENCE TO ACTION

Mindfulness-based therapies appear to alleviate stress and anxiety but are ineffective in reducing depression and burden in caregivers of persons living with dementia. Well-designed RCTs with more rigorous methodology and a larger sample size should be conducted to firm the conclusion of the effectiveness of mindfulness-based interventions for caregivers of persons living with dementia.

Strategies and factors to enhance active participation of family caregivers of people with dementia in psychoeducation: A scoping review

Psychoeducation with an active participation component is effective in facilitating family caregivers of people living with dementia to learn about the disease and gain relevant caregiving skills. However, research into the best strategies to promote active participation has received little attention, and the factors hindering active participation are also unknown. Therefore, the nine-stage framework of the Joanna Briggs Institute methodology for scoping reviews was adopted to map and identify information about the active participation of family caregivers of people living with dementia in psychoeducation. The search criteria focused on identifying primary research studies and grey literature relevant to psychoeducation with active participation that had the family caregivers of community dwelling people living with dementia as the target population. Two reviewers independently screened and selected items from the literature. Content analysis was conducted to thematically synthesise strategies mentioned in 29 articles published from 2011 and 2021. Content analysis revealed six strategies that promoted active participation: (1) the involvement of interventionist and qualifications; (2) the teaching and learning methods used to conduct psychoeducation with active participation; (3) tailoring the contents and formats to the experiences, preferences, and resources of the caregivers; (4) collaborating with caregivers; (5) facilitating sharing and support between peers; and (6) providing experiential learning opportunities. Two factors hindering active caregiver participation were negative caregiver emotions and cultural taboos. This review offers ideas for evidence-based practices that can be used by health and social care providers when planning psychoeducation with active participation for the family caregivers of people living with dementia.

Face-to-face versus telephone-based cognitive-behavioral therapy for family caregivers of people with dementia

OBJECTIVE

The objective was to directly compare the effects and acceptability of telephone-based (TEL-CBT) with face-to-face cognitive-behavioral therapy (F2F-CBT) for family caregivers of people with dementia (PwD).

METHOD

Caregivers for whom F2F participation was possible were allocated to F2F-CBT (n = 49). The other participants were randomized to TEL-CBT (n = 139) or CG (n = 134). CBT consisted of 12 sessions over 6 months.

RESULTS

TEL-CBT yielded significantly better physical health (d = 0.27) and coping with daily hassles (d = 0.38) at posttest compared to F2F-CBT. Therapist competence, acceptability, and outcomes at follow-up did not differ between TEL-CBT and F2F-CBT.

CONCLUSIONS

TEL-CBT is a valuable alternative to F2F-CBT for family caregivers of PwD as TEL-CBT has the advantage of higher accessibility while it does not significantly differ from F2F-CBT in effectiveness and caregivers' evaluation of the setting, their experience with the therapist, and their satisfaction.

Sequential multiple assignment randomised controlled trial protocol for developing an adaptive intervention to improve depressive symptoms among family caregivers of people with dementia

OBJECTIVES

Family caregivers of people with dementia (FC-of-PWD) suffer from a high level of stress and depressive symptoms, which usually require different interventions at different stages. Although some standalone interventions such as behavioural activation (BA) and mindfulness practice (MP) have been shown to be potentially effective at reducing depressive symptoms, the best sequence and combination of these interventions for caregivers are unknown. This study aims to develop and identify a two-stage adaptive intervention with prespecified rules guiding whether, how or when to offer different interventions initially/over time to reduce depressive symptoms in FG-of-PWD.

METHODS

A sequential multiple assignment randomised trial design will be adopted. 272 FG-of-PWD with mild to moderate depressive symptoms will be recruited from the community. Four two-stage, embedded adaptive interventions involving BA and MP of different sequences and dosages (eg, 8 weeks of BA followed by booster sessions for responders and 8 weeks of MP for non-responders) will be assigned to the participants following a set of decision rules. The primary outcomes will be depressive symptoms (measured using the Patient Health Questionnaire-9), assessed after the second stage of the intervention. Other outcomes, such as positive aspects of caregiving (measured using the Positive Aspects of Caregiving Scale), sleep quality (measured using the Pittsburgh Sleep Quality Index) and time points will also be assessed. The analyses will follow the intention-to-treat principle. Several process indicators (eg, engagement in meaningful activities and level of mindfulness) will also be assessed. The findings will have strong implications for the further development of psychosocial adaptive interventions to reduce depressive symptoms among FC-of-PWD.

ETHICS AND DISSEMINATION

This study has received ethical approval from the Human Research Ethics Committee at The Hong Kong Polytechnic University (HSEARS20211223001). The findings will be presented at academic conferences and submitted to peer-reviewed journals for publication.

Qualitative Evaluation of Family Caregivers' Experiences Participating in Knowledge and Interpersonal Skills to Develop Exemplary Relationships (KINDER): Web-Based Intervention to Improve Relationship Quality

BACKGROUND

The onset of Alzheimer disease and related dementias (AD/ADRD) can alter relationships between family caregivers and persons living with AD/ADRD, such as through the occurrence of distressful behavioral and psychological symptoms of dementia. Poorly perceived relationship quality by caregivers contributes to negative outcomes for both care partners, such as low-quality caregiving and potential mistreatment of older adults. Knowledge and Interpersonal Skills to Develop Exemplary Relationships (KINDER) is a new, web-based, asynchronous psychoeducational intervention with content informed by focus groups with family caregivers. The program was developed to prevent low-quality caregiving and potential mistreatment of older adults by focusing on building healthy caregiving relationships.

OBJECTIVE

The purpose of this study is to describe caregivers' experiences participating in KINDER to understand intervention acceptability. Of particular interest was learning how comfortable caregivers were viewing content addressing potential mistreatment, as well as whether asynchronous delivery created any barriers to participating in the intervention. Findings will inform future program refinements before efficacy testing.

METHODS

Although 23 caregivers enrolled in the KINDER parent study, only 7 of them completed the 8-week intervention. In-depth, semistructured qualitative interviews were conducted with all participants who completed the program to understand their experiences while attending KINDER and to decipher barriers to participation. We also asked participants about which program elements were most valuable and which were least valuable to them, as well as how the program could be improved. Interview transcripts were analyzed by 2 coders using thematic analysis.

RESULTS

Our findings indicate that caregivers were overall satisfied with KINDER's focus and content. Participants particularly liked how KINDER materials felt authentic and relevant to supporting healthy care relationships (Theme 1). The program's multiple components were found to be valuable, especially story-based video vignettes and readings (Theme 2). Most caregivers were comfortable viewing depictions of mistreatment and understood the importance of this content (Theme 3). Notably, while caregivers appreciated the convenience of participating in an asynchronous web-based intervention, several expressed a desire for more opportunities to speak with other caregivers (Theme 4). Technology challenges, such as a lack of clarity about automated intervention activities, deterred completion.

CONCLUSIONS

Findings from this study suggest an asynchronous web-based intervention covering sensitive topics such as mistreatment is acceptable for at least some AD/ADRD caregivers. Caregivers' comments that materials felt authentic may suggest that the integration of caregiver voices before intervention development enhanced the relevance of content. To make KINDER easier to deliver and participate in, the investigators plan to reduce the use of automation and integrate more group-based programming, as recommended by participants. Further, given the higher-than-expected dropout rate, in future studies, the investigators will collect data to determine the reasons for participants not completing study activities.

The Relationship between Personal and Contextual Factors and Participation Restriction in Mid-Life Caregivers

OBJECTIVES

Mid-life family caregivers (CGs) are at risk for participation restriction, which can worsen quality of care for care recipients (CR) and increase CG burden and poor health. We aimed to identify factors associated with participation restriction in mid-life CGs.

METHODS

This was a cross-sectional study of CGs aged 40-64 years (n = 1100) from the 2015 cohort of the National Study of Caregiving (NSOC)/National Health and Aging Trends Study (NHATS). Multivariate logistic regression was used to evaluate personal and caregiving attributes associated with restricted participation.

RESULTS

Individual items from the negative and Positive aspects of caregiving (PAC) scales were associated with participation restriction. Mid-life caregivers with "frequent changes to caregiving routine" and "no time for self" were more likely to report restricted participation and those feeling "closer to the CR" were less likely to report restricted participation.

DISCUSSION

Interventions to optimize caregiving routines and improve dyadic relationships could decrease participation restriction in mid-life CGs.

Telehealth applications used for self-efficacy levels of family caregivers for individuals with dementia: A systematic review and Meta-analysis

BACKGROUND

The effectiveness of telehealth applications for family caregivers of individuals with dementia remains unclear. The aim of this study is to investigate how telehealth-based interventions applied for family caregivers of individuals with dementia affect their self-efficacy levels, caregiving burden, stress, depression, and quality of life.

MATERIALS AND METHODS

This was a systematic review. Screening took place between April 30 and May 5, 2022, for the scope of the past 10 years (January 2012/May 2022). The related studies were screened over ten (10) databases and search engines both in English and Turkish, including CINAHL, Cochrane Library, MEDLINE, PsycINFO, PubMed and Web of Science, ULAKBIM, Turkish Medline, Türkiye Klinikleri, and YOK National Thesis Center. Keywords included in various medical topic titles identified upon consultation with literature review experts from a library. Methodological quality of the studies was evaluated using Critical Appraisal Checklists developed by the Joanna Briggs Institute for experimental and quasi-experimental studies. The data were synthesized by meta-analysis.

RESULTS

Two hundred and twelve (212) records were accessed in the databases. Of that, 12 studies (covering 1,013 caregivers) were selected for the meta-analysis. Statistically, the self-efficacy mean score was significantly higher in the intervention group than the control group after the intervention (SMD: 1.08, Z= 3.12, p= 0.002). The effectiveness of telehealth-based applications for caregivers' caregiving burden, stress, depression and quality of life -- except for self-efficacy - was evaluated. The results of the intervention and control groups were similar after the intervention (SMD: -0.17, Z= 0.82, p= 0.41; MD: -0.60, Z= 0.49, p= 0.63, SMD: -0.04, Z= 0.13, p= 0.98; SMD: 0.15, Z= 0.47, p= 0.64, respectively).

CONCLUSIONS

This systematic review and meta-analysis showed that telehealth applications were effective in elevating the self-efficacy levels of caregivers of individuals with dementia. However, no statistically significant difference was observed in terms of caregiving burden, stress, depression, or quality of life for caregivers.

Effects of telehealth intervention for people with dementia and their carers: A systematic review and meta-analysis of randomized controlled studies

PURPOSE

Interventions delivered using telehealth modalities are becoming standard practice with patient populations around the world, partly because of innovation necessitated by the COVID-19 pandemic and partly due to improved infrastructure and comfort of providers, patients, and families, through technology. Though increasingly utilized, the effectiveness of telehealth interventions with families with dementia remains unclear. This gives rise to the need for investigation to develop telehealth interventions that are evidence based and not merely convenient tools. This current study is designed to systematically examine the impact and effectiveness of telehealth-delivered psychoeducational and behavioral interventions among persons with dementia and their caregivers.

DESIGN

The design combines systematic review and meta-analysis.

METHODS

A total of eight databases were electronically accessed and searched as of November 16, 2021. Experimental studies identifying the results of telehealth interventions for persons with dementia and associated caregivers published in English have been reviewed in this study. Standardized mean differences (SMD) offering 95% confidence intervals (CI) were developed to pool the effect size using a random effects model (in this case, Stata 16.0). The Revised Cochrane Risk-of-Bias Tool for Randomized Trials (RoB-2) was used to analyze the study's methodological soundness.

FINDINGS

Nineteen cases met the eligibility criteria (including 1379 persons with dementia and 1339 caregivers). Overall, telehealth interventions demonstrated effects in the expected directions on depression (SMD -0.63; 95% degree of confidence intervals (CI) -0.88 to -0.38, p < 0.001); and caregivers' perceived competency (SMD 0.27; 95% CI -0.05 to 0.50, p = 0.02). There were, however, no statistically significant effects observed on cognitive function or multiple aspects of quality of life for subjects.

CONCLUSIONS

Telehealth interventions appear to effect a reduction in depression among persons diagnosed with dementia while improving the perceived competency of caregivers.

CLINICAL RELEVANCE

The study's results could be used as evidence of the effectiveness of using telehealth for persons with dementia and their caregivers, including contextualizing where they are used (i.e., long-term care facilities, private homes, etc.), understanding the mechanisms in play (including intervention delivery and systems), and isolating and identifying mediating influences.

Telephone-Based Behavioral Activation for Improving Sleep Quality in Family Caregivers of People With Dementia: A Pilot Randomized Controlled Trial

Sleep disturbances are common among family caregivers of people with dementia (PWD). Although behavioral activation (BA) shows the potential to improve sleep quality, to date, evidence for this treatment's feasibility and efficacy for family caregivers of PWD is limited. Therefore, this study pilot tested an evidence-based BA protocol for improving sleep quality in Chinese family caregivers of PWD. The BA intervention involved eight weekly individual telephone-based sessions designed to teach caregivers specific BA techniques. Sleep quality and depression were measured using the Chinese versions of the Pittsburgh Sleep Quality Index (PSQI) and Center for Epidemiologic Studies Depression (CES-D) Scale, respectively. This study also measured leisure activity, positive aspect of caregiving, caregiving burden, health status, and relationship satisfaction. All participants were asked to complete the assessments on paper at baseline and immediately after the intervention. After completing the pilot randomized controlled trial, semistructured interviews were conducted to explore participants' experiences participating in the BA intervention. A total of 71 family caregivers of PWD (35 in the intervention group and 36 in the control group) were recruited. The majority of participants were female (n = 53, 74.65%), and their mean age was 54.07 years (SD = 10.95). Compared with controls, caregivers in the intervention group displayed significantly greater improvement in sleep quality, as well as perceptions of positive aspects of caregiving and reduction of depression. Most participants were very satisfied with the intervention. These findings suggest that individual telephone-based BA interventions are feasible, acceptable, and effective in improving sleep quality and psychological health in family caregivers of PWD. These results contribute to the literature by providing evidence for developing effective, accessible, and sustainable BA interventions for family caregivers of PWD.

Family caregivers' perceptions and experiences of participating in the learning skills together intervention to build self-efficacy for providing complex care

The purpose of this study was to describe how an intervention to teach family caregivers of persons living with dementia to provide complex care tasks contributes to their self-efficacy. This qualitative study was embedded in a pilot study evaluating the intervention. Semi-structured interviews were conducted with 15 caregivers who had completed the intervention. Content analysis was used to analyze the data. Themes identified from the interviews were: "helpfulness of the content", "if they can do it, so can I", and "applying what I have learned". Caregivers described the helpfulness of learning from expert healthcare professionals in a supportive environment. They valued the group setting, including interacting with and learning from their peers. Caregivers demonstrated mastery of the content by applying it to their caregiving situations and sharing information with other family members. These findings provide insights into successful elements in a complex care intervention that contributed to building caregiver self-efficacy.

"Am I entitled to take a break in caregiving?": Perceptions of leisure activities of family caregivers of loved ones with dementia in China

Leisure activities are essential for family caregivers of loved ones with dementia living in the community, yet these caregivers tend not to engage in them, especially in China, wherein it may have a negative impact on their physical and psychological health. To date, limited knowledge exists regarding underlying reasons that deter these family caregivers from doing leisure activities. This study aims to explore perceptions of family caregivers of people living with dementia and their engagement in leisure activities. A qualitative descriptive research design was used with semi-structured, face-to-face, individual in-depth interviews. The data were collected in Shijiazhuang, China between October and November 2019. Content analysis was used to develop categories. Results of 20 family caregivers (5 men and 15 women, mean age = 55.6±12.7) reported their perceptions under four main categories: (i) "the condition of leisure life," (ii) "needs for leisure activities," (iii) "reasons for the reluctance to do leisure activities," and (iv) "motivations supporting the implementation of leisure activities." In addition to the heavy caregiving workload and lack of support, traditional Chinese beliefs including filial commitment and "fatalistic voluntarism" were the reasons that prevented Chinese family caregivers of people living with dementia from doing leisure activities. However, engaging their loved ones in leisure activities, like doing exercise together, could motivate family caregivers themselves to participate in leisure activities. These findings encourage healthcare professionals to consider the influence of culture on family caregivers' engagement in leisure activities which is one of the ways to reduce stress. Family caregivers may benefit from the leisure activities by learning how to better cope with and balance caregiving tasks with their leisure pursuits in the community.

Depression among caregivers of patients with dementia: Associative factors and management approaches

As elderly people increasingly come to represent a higher proportion of the world’s population, various forms of dementia are becoming a significant chronic disease burden. The World Health Organization emphasizes dementia care as a public health priority and calls for more support for family caregivers who commonly play a significant, central role in dementia care. Taking care of someone with dementia is a long-term responsibility that can be stressful and may lead to depression among family caregivers. Depression and related behavioral and cognitive changes among caregivers could in turn affect the status and prognosis of the dementia patient. This review article explores depression in dementia caregivers and summarizes proposed mechanisms, associated factors, management and research findings, and proposes future research directions.

An individualized telephone-based care support program for rural family caregivers of people with dementia: study protocol for a cluster randomized controlled trial

Background

There are about 9.5 million people with dementia in China. Up to 99% of them are cared for by their family caregivers. Family caregivers are confronted with considerable difficulties and challenges while providing care. They often experience high levels of emotional, physical, financial, and social burdens. Caregivers in rural areas experience an even higher level of burden compared to their counterparts in urban areas due to fewer health resources for dementia care. However, so far, no intervention study has been conducted to support family caregivers in rural areas of China. The aim of this proposed study is to adapt and evaluate an evidence-based and culturally-tailored individualized telephone-based care support (ITBCS) program for family caregivers of people with dementia in rural China.

Methods

A cluster randomized controlled trial (RCT) will be conducted to evaluate the effectiveness of the ITBCS compared with usual care for Chinese rural family caregivers of people with dementia. A total sample of 168 rural family caregivers will be recruited. The intervention components consist of a 3-month intensive telephone-based care support intervention followed by telephone-based follow-up consultations for 6 months. The control group will receive usual care services available for them. Outcome measures include carers’ subjective burden, depressive symptoms, health-related quality of life, social support, caregiving self-efficacy, and care recipients’ difficult behaviours and competence in activities of daily living at 3, 9 and 15 months after baseline. The potential cost-effectiveness of the ITBCS compared with usual care will be assessed as well.

Discussion

If effective, the ITBCS program can be adapted and used in rural areas of China as a blueprint to improve the quality of home-based care for people with dementia. Findings from the present study are significant for developing evidence-based dementia care policy in rural China.

Remotely delivered information, training and support for informal caregivers of people with dementia

BACKGROUND

Many people with dementia are cared for at home by unpaid informal caregivers, usually family members. Caregivers may experience a range of physical, emotional, financial and social harms, which are often described collectively as caregiver burden. The degree of burden experienced is associated with characteristics of the caregiver, such as gender, and characteristics of the person with dementia, such as dementia stage, and the presence of behavioural problems or neuropsychiatric disturbances. It is a strong predictor of admission to residential care for people with dementia. Psychoeducational interventions might prevent or reduce caregiver burden. Overall, they are intended to improve caregivers' knowledge about the disease and its care; to increase caregivers' sense of competence and their ability to cope with difficult situations; to relieve feelings of isolation and allow caregivers to attend to their own emotional and physical needs. These interventions are heterogeneous, varying in their theoretical framework, components, and delivery formats. Interventions that are delivered remotely, using printed materials, telephone or video technologies, may be particularly suitable for caregivers who have difficulty accessing face-to-face services because of their own health problems, poor access to transport, or absence of substitute care. During the COVID-19 pandemic, containment measures in many countries required people to be isolated in their homes, including people with dementia and their family carers. In such circumstances, there is no alternative to remote delivery of interventions.

OBJECTIVES

To assess the efficacy and acceptability of remotely delivered interventions aiming to reduce burden and improve mood and quality of life of informal caregivers of people with dementia.

SEARCH METHODS

We searched the Specialised Register of the Cochrane Dementia and Cognitive Improvement Group, MEDLINE, Embase and four other databases, as well as two international trials registries, on 10 April 2020. We also examined the bibliographies of relevant review papers and published trials.

SELECTION CRITERIA

We included only randomised controlled trials that assessed the remote delivery of structured interventions for informal caregivers who were providing care for people with dementia living at home. Caregivers had to be unpaid adults (relatives or members of the person's community). The interventions could be delivered using printed materials, the telephone, the Internet or a mixture of these, but could not involve any face-to-face contact with professionals. We categorised intervention components as information, training or support. Information interventions included two key elements: (i) they provided standardised information, and (ii) the caregiver played a passive role. Support interventions promoted interaction with other people (professionals or peers). Training interventions trained caregivers in practical skills to manage care. We excluded interventions that were primarily individual psychotherapy. Our primary outcomes were caregiver burden, mood, health-related quality of life and dropout for any reason. Secondary outcomes were caregiver knowledge and skills, use of health and social care resources, admission of the person with dementia to institutional care, and quality of life of the person with dementia.

DATA COLLECTION AND ANALYSIS

Study selection, data extraction and assessment of the risk of bias in included studies were done independently by two review authors. We used the Template for Intervention Description and Replication (TIDieR) to describe the interventions. We conducted meta-analyses using a random-effects model to derive estimates of effect size. We used GRADE methods to describe our degree of certainty about effect estimates.

MAIN RESULTS

We included 26 studies in this review (2367 participants). We compared (1) interventions involving training, support or both, with or without information (experimental interventions) with usual treatment, waiting list or attention control (12 studies, 944 participants); and (2) the same experimental interventions with provision of information alone (14 studies, 1423 participants). We downgraded evidence for study limitations and, for some outcomes, for inconsistency between studies. There was a frequent risk of bias from self-rating of subjective outcomes by participants who were not blind to the intervention. Randomisation methods were not always well-reported and there was potential for attrition bias in some studies. Therefore, all evidence was of moderate or low certainty. In the comparison of experimental interventions with usual treatment, waiting list or attention control, we found that the experimental interventions probably have little or no effect on caregiver burden (nine studies, 597 participants; standardised mean difference (SMD) -0.06, 95% confidence interval (CI) -0.35 to 0.23); depressive symptoms (eight studies, 638 participants; SMD -0.05, 95% CI -0.22 to 0.12); or health-related quality of life (two studies, 311 participants; SMD 0.10, 95% CI -0.13 to 0.32). The experimental interventions probably result in little or no difference in dropout for any reason (eight studies, 661 participants; risk ratio (RR) 1.15, 95% CI 0.87 to 1.53). In the comparison of experimental interventions with a control condition of information alone, we found that experimental interventions may result in a slight reduction in caregiver burden (nine studies, 650 participants; SMD -0.24, 95% CI -0.51 to 0.04); probably result in a slight improvement in depressive symptoms (11 studies, 1100 participants; SMD -0.25, 95% CI -0.43 to -0.06); may result in little or no difference in caregiver health-related quality of life (two studies, 257 participants; SMD -0.03, 95% CI -0.28 to 0.21); and probably result in an increase in dropouts for any reason (12 studies, 1266 participants; RR 1.51, 95% CI 1.04 to 2.20).

AUTHORS' CONCLUSIONS

Remotely delivered interventions including support, training or both, with or without information, may slightly reduce caregiver burden and improve caregiver depressive symptoms when compared with provision of information alone, but not when compared with usual treatment, waiting list or attention control. They seem to make little or no difference to health-related quality of life. Caregivers receiving training or support were more likely than those receiving information alone to drop out of the studies, which might limit applicability. The efficacy of these interventions may depend on the nature and availability of usual services in the study settings.

Long-Term Effects of a Cognitive Behavioral Conference Call Intervention on Depression in Non-Professional Caregivers

Recent evidence supports the efficacy of conference call cognitive-behavioral interventions in preventing depression in caregivers at post-intervention, but we do not know whether the results are sustained long term. The main objective of this study was to evaluate the long-term efficacy of a cognitive-behavioral intervention administered by telephone conference call in preventing depression in caregivers with elevated depressive symptoms, comparing all components of the intervention versus only the behavioral ones. A randomized controlled trial was conducted using a dismantling strategy. At total of 219 caregivers were randomly assigned to a cognitive-behavioral conference call intervention (CBCC; n = 69), a behavioral-activation conference call intervention (BACC; n = 70), or a usual care control group (CG, n = 80). Information was collected on depressive symptoms and depression at pre-intervention and at 1, 3, 6, 12, and 36 months post-intervention. At 36 months, there was a reduction in depressive symptoms (p < 0.001) and a lower incidence of major depressive episodes in both the CBCC and BACC groups compared to CG (8.7%, 8.6%, and 33.7%, respectively). The results show that a conference call intervention was effective in the long term to prevent depression in caregivers and that the behavioral-activation component was comparable to the complete cognitive-behavioral protocol.

Behavioural activation for family dementia caregivers: A systematic review and meta-analysis

The current study aims to investigate the effectiveness of behavioral activation (BA) for family dementia caregivers. A systematic literature search was conducted through PubMed, Medline, CINAHL, Cochrane, Embase and PsycINFO for studies published from March 1988 to September 2019. Standardized mean differences (SMDs) were combined to synthesize pooled effect measures using random effects. The review was based on ten randomized controlled trials. Depression was significantly reduced after participants received BA (n = 9; 786 participants; SMD = -0.69; 95% CI: -1.12 to -0.25; p = 0.002). BA also has a positive impact on other areas of psychological health (e.g., self-efficacy, anxiety, and distress) and physical health (e.g., interleukin-6) in family dementia caregivers. In conclusion, BA not only has a moderate effect on reducing depression but also has the potential to improve other areas of psychological and cardiovascular health in family caregivers. However, more interventional studies of BA for family dementia caregivers are needed.

Sense of Community Mediating Between Age-Friendly Characteristics and Life Satisfaction of Community-Dwelling Older Adults

The growth of age-friendly community initiatives underscores a paradigmatic shift from the individual to the community, addressing dynamic transactions between people and the environment they are living in. The purpose of the present study is to address the gap in existing research by examining the psycho-social effects of the sense of community in mediating between WHO domains of age-friendliness and the life satisfaction of older adults. Data were obtained from 898 participants in Hong Kong. Path analysis was conducted. Two AFC domains, Social Participation as well as Community Support and Health Services, were found to be associated with life satisfaction. Sense of community was found to mediate between these two domains and life satisfaction. The implications of these findings are discussed with reference to developing opportunities in social participation of older adults and enhancing community/health support services in the context of developing sustainability in the community.
