Do changes in coping style explain the effectiveness of interventions for psychological morbidity in family carers of people with dementia? A systematic review and meta-analysis

Statistical analysis plan for HOMESIDE: a randomised controlled trial for home-based family caregiver-delivered music and reading interventions for people living with dementia

BACKGROUND

Most people with dementia live in the community, not in residential care. Therefore, quality informal care for them is critical for managing behavioural and psychological symptoms of dementia (BPSD). Music therapy has been shown to reduce BPSD. However, no randomised controlled trial has examined the effects of music interventions delivered by caregivers in home settings. The HOME-based caregiver-delivered music intervention for people living with dementia (HOMESIDE) trial aims to evaluate the effectiveness of a 12-week music intervention in addition to standard care for BPSD. This article describes the statistical analysis plan.

METHODS AND ANALYSIS

HOMESIDE is a large, pragmatic international three-arm parallel-group randomised controlled trial. Dyads (persons with dementia and caregiver) in Australia, Germany, the UK, Poland and Norway were randomised to receive music and standard care, reading and standard care or standard care alone. The primary outcome is BPSD (proxy) of the person living with dementia, measured using the Neuropsychiatric Inventory-Questionnaire (NPI-Q) at 90 and 180 days post-randomisation. Longitudinal analysis will compare NPI-Q severity between music and standard care versus standard care alone. Secondary outcomes include quality of life and depression (both person with dementia and caregiver), cognition (person with dementia only), distress, resilience, competence and caregiver-patient relationship (caregiver only). Treatment effects will be obtained at 90 and 180 days post-randomisation, where applicable. Safety outcomes (adverse events, hospitalisations, deaths) will be summarised.

DISCUSSION

This statistical analysis plan provides a detailed methodology for the analysis of HOMESIDE and will improve the validity of the study and reduce the potential for bias.

Effects of the STress-And-coping suppoRT (START) intervention on depression and coping of Chinese women seeking a first-trimester abortion: A randomized controlled trial

BACKGROUND

Abortion is a stressful life event associated with wide variability in women's perceptions and adjustment. There is scarce evidence on interventions to help women cope with abortion and achieve positive psychological health outcomes. This study tested the effect of a stress and coping theory-formed intervention (START) on depression and coping of Chinese women undergoing a first-trimester abortion.

METHODS

A randomized controlled trial was conducted at a Chinese metropolitan hospital. 110 participants were recruited and randomized to intervention group (START + standard care) or control group (standard care) with a 1:1 allocation ratio. The primary outcome was depression at two-week post-abortion. Surveys were completed by participants when they sought abortion services (baseline), two and six-week post-abortion.

RESULTS

At two-week post-abortion, women allocated to the intervention group compared to the control group, had significantly lower depression scores (aOR -2.81 [-4.12 to -1.50]), higher problem-focused coping (aOR 1.64 [0.36-2.93]), lower dysfunctional coping (aOR -2.29 [-3.69 to -0.89]), higher self-efficacy (aOR 3.17 [-0.42-5.94]), and higher personal growth scores (aOR 4.41 [0.30-8.53]). Lower depression scores at two-weeks were mediated by lower dysfunctional coping (mediated effect 0.96 [0.25, 1.74]; proportion of overall effect 36 % [9 %, 65 %]).

CONCLUSION

Chinese women allocated to receive START had lower depression and better coping at two-week post-abortion. This brief, online intervention contributed to women's self-efficacy and positive perceptions of social support, abortion experience, and personal growth. Maintenance of the effects need further research.

Mindfulness-Based Intervention for Caregivers of Frail Older Chinese Adults: A Study Protocol

Studies have consistently showed that informal caregivers have worse health, more medical consultations, anxiety and depression, and lower quality of life than those who do not provide such care. Positive outcomes of psychoeducation interventions have been found, but many of them are relatively long in duration, making them less cost-effective in implementation. The proposed study is a multi-site, three-arm randomized controlled trial of a mindfulness-based intervention for Chinese family caregivers. Effects of the intervention will be compared with those of an evidence-based psychoeducation program and treatment-as-usual. Two hundred forty cross-generational caregivers of frail older adults with moderate to severe levels of frailty will be recruited and randomly assigned to mindfulness-based intervention, psychoeducation, and treatment-as-usual experimental conditions. Program effectiveness will be analyzed on measures of caregiver burden, depression, anxiety, positive caregiving experience, spirituality, family conflict, and the biomarker of heart rate variability. Measures on coping styles, experiential avoidance, and self-efficacy will be explored to see if they mediate the changes to participant improvements in outcomes. Six-month follow-up will be included to investigate the maintenance effects. This study will provide evidence on mindfulness-based interventions on caregivers of frail older adults and expand the existing models of intergenerational caregiving in Chinese culture.

Components, impacts and costs of dementia home support: a research programme including the DESCANT RCT

Background

Over half of people with dementia live at home. We know little about what home support could be clinically effective or cost-effective in enabling them to live well.

Objectives

We aimed to (1) review evidence for components of home support, identify their presence in the literature and in services in England, and develop an appropriate economic model; (2) develop and test a practical memory support package in early-stage dementia, test the clinical effectiveness and cost-effectiveness of routine home support in later-stage dementia and design a toolkit based on this evidence; and (3) elicit the preferences of staff, carers and people with dementia for home support inputs and packages, and evaluate the cost-effectiveness of these approaches in early- and later-stage dementia.

Design

We undertook (1) an evidence synthesis, national surveys on the NHS and social care and an economic review; (2) a multicentre pragmatic randomised trial [Dementia Early Stage Cognitive Aids New Trial (DESCANT)] to estimate the clinical effectiveness and cost-effectiveness of providing memory aids and guidance to people with early-stage dementia (the DESCANT intervention), alongside process evaluation and qualitative analysis, an observational study of existing care packages in later-stage dementia along with qualitative analysis, and toolkit development to summarise this evidence; and (3) consultation with experts, staff and carers to explore the balance between informal and paid home support using case vignettes, discrete choice experiments to explore the preferences of people with dementia and carers between home support packages in early- and later-stage dementia, and cost–utility analysis building on trial and observational study.

Setting

The national surveys described Community Mental Health Teams, memory clinics and social care services across England. Recruitment to the trial was through memory services in nine NHS trusts in England and one health board in Wales. Recruitment to the observational study was through social services in 17 local authorities in England. Recruitment for the vignette and preference studies was through memory services, community centres and carers’ organisations.

Participants

People aged > 50 years with dementia within 1 year of first attendance at a memory clinic were eligible for the trial. People aged > 60 years with later-stage dementia within 3 months of a review of care needs were eligible for the observational study. We recruited staff, carers and people with dementia for the vignette and preference studies. All participants had to give written informed consent.

Main outcome measures

The trial and observational study used the Bristol Activities of Daily Living Scale as the primary outcome and also measured quality of life, capability, cognition, general psychological health and carers’ sense of competence.

Methods

Owing to the heterogeneity of interventions, methods and outcome measures, our evidence and economic reviews both used narrative synthesis. The main source of economic studies was the NHS Economic Evaluation Database. We analysed the trial and observational study by linear mixed models. We analysed the trial by ‘treatment allocated’ and used propensity scores to minimise confounding in the observational study.

Results

Our reviews and surveys identified several home support approaches of potential benefit. In early-stage dementia, the DESCANT trial had 468 randomised participants (234 intervention participants and 234 control participants), with 347 participants analysed. We found no significant effect at the primary end point of 6 months of the DESCANT intervention on any of several participant outcome measures. The primary outcome was the Bristol Activities of Daily Living Scale, for which scores range from 0 to 60, with higher scores showing greater dependence. After adjustment for differences at baseline, the mean difference was 0.38, slightly but not significantly favouring the comparator group receiving treatment as usual. The 95% confidence interval ran from –0.89 to 1.65 (p = 0.56). There was no evidence that more intensive care packages in later-stage dementia were more effective than basic care. However, formal home care appeared to help keep people at home. Staff recommended informal care that cost 88% of formal care, but for informal carers this ratio was only 62%. People with dementia preferred social and recreational activities, and carers preferred respite care and regular home care. The DESCANT intervention is probably not cost-effective in early-stage dementia, and intensive care packages are probably not cost-effective in later-stage dementia. From the perspective of the third sector, intermediate intensity packages were cheaper but less effective. Certain elements may be driving these results, notably reduced use of carers’ groups.

Limitations

Our chosen outcome measures may not reflect subtle outcomes valued by people with dementia.

Conclusions

Several approaches preferred by people with dementia and their carers have potential. However, memory aids aiming to affect daily living activities in early-stage dementia or intensive packages compared with basic care in later-stage dementia were not clinically effective or cost-effective.

Future work

Further work needs to identify what people with dementia and their carers prefer and develop more sensitive outcome measures.

Interventions to Improve Health and Well-Being Among Family Caregivers of Older Adults With Chronic Illnesses: A Scoping Review

Caregivers of older adults with chronic illnesses often face challenges that harm their health and well-being. Evidence-based strategies are needed to address such outcomes. The current study aims to synthesize interventions designed to improve the health and well-being of caregivers of older adults with chronic illnesses. Search strategies included investigating four databases (e.g., PubMed, CINAHL), as well as conducting bibliographic, hand, and author searches. Eligible studies were randomized controlled trials conducted between 2009 and 2019 that included family caregivers of older adults with chronic illnesses aged ≥65 and that reported care-giver health or well-being outcomes. Data from 24 eligible studies were extracted, analyzed, and narratively synthesized. Although intervention characteristics were diverse (e.g., strategies, interventionists), most improved health and well-being. Thus, providers have an array of interventions available to them to help caregivers. Future caregiver research should examine theory-driven interventions among diverse samples, clearly report intervention dose, and measure physical health.

The Effect of a Nurse-Led Cognitive Behavioral Protocol on Depressive Symptoms and Coping Strategies of Dementia Caregivers

BACKGROUND

Family caregivers of patients with dementia (PWD) often experience depressive symptoms and use poor coping strategies. Cognitive behavioral interventions may enhance positive appraisals of caregiving-related issues and the utilization of active coping strategies among caregivers, which may help prevent caregiver depression. However, there is a shortage of primary, community-based mental health services in China, and little research has been conducted on the effect of nurse-led mental health programs in this population.

PURPOSE

This study explored the effect of a nurse-led cognitive behavioral intervention on depressive symptoms and coping strategies among family caregivers of PWD in China.

METHODS

This randomized controlled trial used data from a sample of 112 caregivers screened from 276 potential participants in a city in southeastern China. The sample was randomly assigned to an intervention group (n = 56) and a control group (n = 56). The intervention group received five monthly in-home, nurse-led cognitive behavioral sessions and telephone consultations after each session. The control group received five monthly, short, general conversations with nurse interventionists at the participants' homes, in the hospital, or via telephone. Depressive symptoms, coping strategies, and the demographics of caregiving dyads were collected at Time 1 (baseline), Time 2 (the end of the 5-month intervention), and Time 3 (2-month follow-up). IBM SPSS Statistics Version 19.0 was used for data analysis.

RESULTS

Eighty-two participants (intervention group: n = 47, control group: n = 35) completed the three evaluations. No significant group differences were found in baseline characteristics between the two groups. The general linear model repeated-measures analysis of variance indicated a significant difference in depressive symptoms and active coping between groups over time, with p < .001 for the interaction between depressive symptoms and groups and p < .01 for the interaction between active coping and groups. A similar result did not occur for passive coping. The t tests further supported a significant interventional effect on participants' depressive symptoms and active coping.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

This nurse-led cognitive behavioral intervention was effective in decreasing depressive symptoms and improving active coping among study participants. The findings suggest the improvement of mental health services and social policies in China to support family caregivers of PWD.

A comprehensive meta-review of systematic reviews and meta-analyses on nonpharmacological interventions for informal dementia caregivers

Background

Many reviews with conflicting findings on dementia caregiver interventions have been published. A meta-review was conducted to synthesize the findings of systematic reviews and meta-analyses.

Methods

MEDLINE, PsycINFO, CINAHL and Cochrane Library were searched to identify reviews published during 2006–2018.

Results

Sixty reviews covering > 500 intervention studies were selected and appraised with Assessment of Multiple Systematic Reviews (AMSTAR) II. The great majority of studies were of low quality according to AMSTAR II, but quality factors appeared unrelated to the conclusions obtained. Depression was most modifiable, with effects found across a spectrum of interventions (psychoeducation, counseling/psychotherapy, occupational therapy, mindfulness-based interventions, multicomponent interventions, etc.). Evidence of intervention effect was also found for quality of life (psychoeducation), mastery (psychoeducation, occupational therapy and multicomponent interventions) and communication skills (communication training). Null or weak results were found for anxiety, social support and burden. Support groups and respite were generally ineffective. There was no evidence that dyadic programs were better than caregiver-only programs, or that programs delivered individually or in groups would differ in their impacts. The evidence also does not support multicomponent interventions to have broader impacts than single-component programs. Methodological issues in the existing reviews (e.g., selective use of studies to serve different research purposes and inconsistent classification of interventions) were noted and taken into account when interpreting findings.

Conclusions

This meta-review clarified variations in review methodology and identified a few potent groups of intervention (most notably psychoeducation, psychotherapy, occupational therapy, and multicomponent interventions), although no intervention type had broad effects on caregiver outcomes. We note that improvements are needed in the reporting of intervention studies and in making the classification of interventions more transparent and consistent. We further recommend fewer and larger-scale reviews and more attention to positive outcomes in order to better inform the field. Developing interventions with broader impacts and packaging them to meet caregivers’ changing needs in the course of dementia should be a priority for researchers and practitioners.

Attempted suicide short intervention program influences coping among patients with a history of attempted suicide

BACKGROUND

The development of individual coping strategies for suicidal crises is essential for suicide prevention. However, the influence of a brief intervention and the effect on coping strategies is largely unknown. This study aimed to investigate the influence of the Attempted Suicide Short Intervention Program on the development of coping strategies, in comparison to a control group.

METHOD

In this secondary analysis of a 24-month follow-up randomised controlled study, 120 patients (55% female; mean age of 36) with a history of suicide attempts were randomly allocated to either the ASSIP group or to a control group, in addition to treatment as usual.

RESULTS

The present study identified 11% less dysfunctional coping in the ASSIP group and 6% more problem-focussed coping compared to the control group after 24-months. The analysis of broader strategies showed a statistically significant group difference regarding self-distraction (after 12-months) and self-blame (after 24-months). In regard to the long-term association between coping strategies and suicidal ideation, active coping and substance use were negatively associated with suicidal ideation in the ASSIP group. Whereas, in the control group, behavioural disengagement and positive reframing were positively and self-distraction was negatively related to suicidal ideation.

LIMITATION

The receipt of a clinical interview and suicide risk assessment in the control group could have potentially had an effect on participants' coping mechanisms.

CONCLUSION

These results indicate that ASSIP may have an impact on the development of problem-focussed coping strategies. Although a reduction in dysfunctional coping seems to be essential in overcoming suicidal crises.

Interventions for reducing levels of burden amongst informal carers of persons with dementia in the community. A systematic review and meta-analysis of randomised controlled trials

Objectives: Caregiver burden can lead to increased stress, depression and health difficulties for caregivers and care-recipients. This systematic review aimed to examine the published evidence, for interventions designed to reduce levels of carer burden, in those caring for a person with dementia. Methods: Three databases were searched (Medline, PsycINFO and CINAHL) for studies reporting on randomised controlled trials of non-pharmacological interventions for dementia-related caregiver burden. Data quality checks were completed for included papers and meta-analysis was performed to estimate the efficacy of individual interventions and different categories of non-pharmacological intervention. Results: Thirty studies were included in the analysis. Seven studies found a significant reduction in carer burden and a pooled effect found that intervening was more effective than treatment as usual (SMD = -0.18, CI = -0.30, -0.05). This result was small, but significant (p = 0.005). Multi-component interventions are more effective than other categories. High heterogeneity means that results should be interpreted with caution. Conclusions: Interventions that significantly reduced levels of burden should be replicated on a larger scale. The relative effectiveness of interventions targeting cognitive appraisals and coping styles suggests that future interventions might be informed by models theorising the role of these processes in carer burden.

HOMESIDE: home-based family caregiver-delivered music and reading interventions for people living with dementia: protocol of a randomised controlled trial

INTRODUCTION

Pharmacological interventions to address behavioural and psychological symptoms of dementia (BPSD) can have undesirable side effects, therefore non-pharmacological approaches to managing symptoms may be preferable. Past studies show that music therapy can reduce BPSD, and other studies have explored how formal caregivers use music in their caring roles. However, no randomised study has examined the effects on BPSD of music interventions delivered by informal caregivers (CGs) in the home setting. Our project aims to address the need for improved informal care by training cohabiting family CGs to implement music interventions that target BPSD, and the quality of life (QoL) and well-being of people with dementia (PwD) and CGs.

METHODS AND ANALYSIS

A large international three-arm parallel-group randomised controlled trial will recruit a sample of 495 dyads from Australia, Germany, UK, Poland and Norway. Dyads will be randomised equally to standard care (SC), a home-based music programme plus SC, or a home-based reading programme plus SC for 12 weeks. The primary outcome is BPSD of PwD (measured using the Neuropsychiatric Inventory-Questionnaire). Secondary outcomes will examine relationship quality between CG and PwD, depression, resilience, competence, QoL for CG and QoL for PwD. Outcomes will be collected at baseline, at the end of the 12-week intervention and at 6 months post randomisation. Resource Utilisation in Dementia will be used to collect economic data across the life of the intervention and at 6-month follow-up. We hypothesise that the music programme plus SC will generate better results than SC alone (primary comparison) and the reading programme plus SC (secondary comparison).

ETHICS AND DISSEMINATION

Ethical approval has been obtained for all countries. Results will be presented at national and international conferences and published in scientific journals and disseminated to consumer and caregiver representatives and the community.

The Role of Mutuality and Coping in a Nurse-Led Cognitive Behavioral Intervention on Depressive Symptoms Among Dementia Caregivers

The current study explored whether mutuality and coping predicted and/or mediated the effect of a nurse-led cognitive behavioral intervention (NLCBI) on depressive symptoms of caregivers of persons with dementia. The intervention group (n = 56) received five monthly in-home nurse-led cognitive behavioral sessions and consultation calls after each session. The control group (n = 56) received five monthly short general conversations with the nurse interventionist. Questionnaires on study variables and demographics were collected at baseline, end of intervention, and 2-month follow up. Improved mutuality (β = -0.75, p = 0.049) and active coping (β = -2.06, p = 0.0001) and decreased passive coping (β = 1.43, p = 0.001) were found to predict the reduction of depressive symptoms among caregivers in the NLCBI. However, none of these variables mediated the interventional effect. Regular mental health nursing interventions are suggested to focus on enhancing mutuality and active coping and decreasing passive coping to maintain caregivers' mental health.

TARGETS

Caregivers of persons with dementia.

INTERVENTION DESCRIPTION

Nurse-led cognitive behavioral sessions and subsequent consultation calls.

MECHANISMS OF ACTION

Impacted caregivers' reappraisals, thus improving their active coping skills and mutuality and decreasing their passive coping, which directly reduced their depressive symptoms.

OUTCOMES

Mutuality, active coping, and passive coping played a predicting, but not mediating, role in the effect of the NLCBI. [Res Gerontol Nurs. 2019; 12(1):44-55.].

Living with a partner with dementia: a systematic review and thematic synthesis of spouses' lived experiences of changes in their everyday lives

OBJECTIVES

Dementia causes dramatic changes in everyday-living for spouses. Occured changes in marital relationship, force spouses to perform more both mentally and physically. Leading to a spousal perceived burden. To improve understanding of spouses' needs, spouses lived experiences is needed. The aim was to identify and synthesise qualitative studies on spouses' lived experiences of living with a partner with dementia.

METHODS

A systematic search was undertaken in January 2017. Six databases (CINAHL, Cochrane Library, Embase, PubMed, PsycINFO and Sociological Abstracts) were searched, using search terms in accordance with PICo. A descriptive synthesis and a thematic synthesis were undertaken.

FINDINGS

Fifteen studies met the inclusion criteria. Three themes derived from the analysis 1) Noticing changes in everyday life 2) Transformation to a new marital relation in everyday life, with corresponding sub-themes; changes in marital relationship, management of the transitioned marital relation in everyday life 3) Planning the future.

CONCLUSION

Findings provide an overview of how spouses notice changes and transform their marital relationships in everyday-life. Findings offer a deeper understanding of changes that occurs over time while the partner is living at home. Findings contribute with knowledge on spouses' experiences of changes in early-stages of dementia. Interventions supporting spouses are needed.

Carer preferences for home support services in later stage dementia

OBJECTIVES

To examine the relative importance of different home support attributes from the perspective of carers of people with later-stage dementia.

METHOD

Preferences from 100 carers, recruited through carers' organisations, were assessed with a Discrete Choice Experiment (DCE) survey, administered online and by paper questionnaire. Attributes were informed by an evidence synthesis and lay consultations. A conditional logit model was used to estimate preference weights for the attributes within a home support 'package'.

RESULTS

The most preferred attributes were 'respite care, available regularly to fit your needs' (coefficient 1.29, p = < 0.001) and 'home care provided regularly for as long as needed' (coefficient 0.93, p = < 0.001). Cost had a significant effect with lower cost packages preferred. Findings were similar regardless of the method of administration, with respite care considered to be the most important attribute for all carers. Carers reported that completing the DCE had been a positive experience; however, feedback was mixed overall.

CONCLUSIONS

These carer preferences concur with emerging evidence on home support interventions for dementia. Respite care, home care and training on managing difficulties provided at home are important components. Carers' preferences revealed the daily challenges of caring for individuals with later stage dementia and the need for tailored and specialised home support.

The self-reported perceptions of the repercussions of the disease and its treatments on daily life for young women with breast cancer and their partners

PURPOSE

This study aimed to compare the self-reported perceptions of the repercussions of the disease and its treatments and emotional distress in young women with breast cancer and their partners.

DESIGN

Cross-sectional study using self-reported questionnaires.

SAMPLE

491 couples in which women were aged <45 years when diagnosed with non-metastatic breast cancer in four different groups of treatment: during chemotherapy with or without Trastuzumab; under Trastuzumab with or without hormone therapy; during hormone therapy; and during the follow-up period.

METHODS

Patients and partners completed a questionnaire assessing their self-reported perceptions of the disease and treatments (Patient YW-BCI and Partner YW-BCI for the partners) and their emotional distress (CESD; STAI).

FINDINGS

Patients reported more difficulties than partners in the management of child(ren) and everyday life, body image and sexuality, negative affectivity about the disease and apprehension about the future, career management, and finances. While the difficulties were generally more marked in the chemotherapy and Trastuzumab groups than in the hormone therapy and follow-up groups, the negative affectivity about the disease and apprehension about the future was high in all four groups, especially in patients. The partners reported more difficulties in sharing with close relatives, and even more in those groups reflecting the latest treatment phases. No difference appeared between patients and partners in couple cohesion and deterioration of relationships with relatives. Partners were less anxious than patients but as depressed as them.

CONCLUSIONS

Difficulties of patients and partners seem particularly severe in the early care pathway, maybe reflecting better adjustment in women under surveillance and their partners. A longitudinal study will substantiate this finding and enable a better identification of some explanatory processes of these differences and similarities in the daily self-reported repercussions of the disease throughout the cancer care pathway. Implications for psychosocial oncology: It seems important to support young women with breast cancer and their partners, as our results evidence distress in both and differences according to the type of treatment the woman is currently receiving. Healthcare providers need consistent methods to identify and respond to couples' distress and reduce significant disparities in support.

People with dementia and carer preferences for home support services in early-stage dementia

OBJECTIVES

To examine people with dementia and carer preferences for home support attributes in early-stage dementia, building on the paucity of evidence in this area.

METHOD

Preferences from 44 people with dementia and 103 carers, recruited through memory clinics and an online questionnaire, were assessed with a Discrete Choice Experiment survey, with attributes informed by an evidence synthesis and lay consultation. A conditional logit model was used to estimate preference weights for the attributes within a home support 'package'.

RESULTS

The most preferred attributes were support with personal feelings and concerns, provided by a trained counsellor at home (coefficient 0.67, p = <0.001) and information on coping with dementia, provided by an experienced worker at home (coefficient 0.59, p = <0.001). However, for people with dementia, opportunities for social and recreational activities were considered the most important (coefficient 0.48, p = <0.001).

CONCLUSIONS

These preferences concur with emerging evidence on psychosocial interventions in dementia. Support with personal feelings, information and social engagement are important components. Additionally, knowledge of preferences of people with dementia and their carers can identify other attributes that may be important to effectiveness in 'living well' but for which there remains limited evidence.

Comparing Crowdsourcing and Friendsourcing: A Social Media-Based Feasibility Study to Support Alzheimer Disease Caregivers

Background

In the United States, over 15 million informal caregivers provide unpaid care to people with Alzheimer disease (AD). Compared with others in their age group, AD caregivers have higher rates of stress, and medical and psychiatric illnesses. Psychosocial interventions improve the health of caregivers. However, constraints of time, distance, and availability inhibit the use of these services. Newer online technologies, such as social media, online groups, friendsourcing, and crowdsourcing, present alternative methods of delivering support. However, limited work has been done in this area with caregivers.

Objective

The primary aims of this study were to determine (1) the feasibility of innovating peer support group work delivered through social media with friendsourcing, (2) whether the intervention provides an acceptable method for AD caregivers to obtain support, and (3) whether caregiver outcomes were affected by the intervention. A Facebook app provided support to AD caregivers through collecting friendsourced answers to caregiver questions from participants’ social networks. The study’s secondary aim was to descriptively compare friendsourced answers versus crowdsourced answers.

Methods

We recruited AD caregivers online to participate in a 6-week-long asynchronous, online, closed group on Facebook, where caregivers received support through moderator prompts, group member interactions, and friendsourced answers to caregiver questions. We surveyed and interviewed participants before and after the online group to assess their needs, views on technology, and experience with the intervention. Caregiver questions were pushed automatically to the participants’ Facebook News Feed, allowing participants’ Facebook friends to see and post answers to the caregiver questions (Friendsourced answers). Of these caregiver questions, 2 were pushed to crowdsource workers through the Amazon Mechanical Turk platform. We descriptively compared characteristics of these crowdsourced answers with the friendsourced answers.

Results

In total, 6 AD caregivers completed the initial online survey and semistructured telephone interview. Of these, 4 AD caregivers agreed to participate in the online Facebook closed group activity portion of the study. Friendsourcing and crowdsourcing answers to caregiver questions had similar rates of acceptability as rated by content experts: 90% (27/30) and 100% (45/45), respectively. Rates of emotional support and informational support for both groups of answers appeared to trend with the type of support emphasized in the caregiver question (emotional vs informational support question). Friendsourced answers included more shared experiences (20/30, 67%) than did crowdsourced answers (4/45, 9%).

Conclusions

We found an asynchronous, online, closed group on Facebook to be generally acceptable as a means to deliver support to caregivers of people with AD. This pilot is too small to make judgments on effectiveness; however, results trended toward an improvement in caregivers’ self-efficacy, sense of support, and perceived stress, but these results were not statistically significant. Both friendsourced and crowdsourced answers may be an acceptable way to provide informational and emotional support to caregivers of people with AD.

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.

Consistency of dementia caregiver intervention classification: an evidence-based synthesis

BACKGROUND

There are many systematic reviews and meta-analyses (SRs) of interventions for family caregivers of persons with Alzheimer's disease or a related dementia. A challenge when synthesizing the efficacy of dementia caregiver interventions is the potential discrepancy in how they are categorized. The objective of this study was to systematically examine inconsistencies in how dementia caregiver interventions are classified.

METHODS

We searched Ovid Medline®, Ovid PsycINFO®, Ovid Embase®, and the Cochrane Library to identify previous SRs published and indexed in bibliographic databases through January 2015. Following a graphical network analysis, open-coding of classification definitions was conducted. A descriptive analysis was then completed to examine classification consistency of individual interventions across SR grouping labels.

RESULTS

Twenty-three SRs were identified. A graphical network analysis revealed a significant amount of overlap in individual studies included across SRs, but stark differences in how reviews labeled or categorized them. The qualitative content analysis identified seven themes; one of these, content of the intervention, was used to compare classification consistency. When subjecting the classification of interventions to descriptive empirical analysis, extensive inconsistency was apparent.

CONCLUSIONS

The substantial inconsistency in how dementia caregiver interventions are classified across SRs has hindered the science and practice of dementia caregiver interventions. Specifically, accurate reporting of intervention components and SRs would allow for more precise assessments of efficacy as well as a fuller determination of how caregiver interventions can best yield benefits for caregivers and persons with dementia.

Caring for relatives with agitation at home: a qualitative study of positive coping strategies

BACKGROUND

Trials of psychological interventions for reducing agitation in people with dementia living at home have been unsuccessful.

AIMS

To inform future interventions by identifying successful strategies of family carers with relatives with dementia and agitation living at home.

METHOD

Qualitative in-depth individual interviews were performed with 18 family carers. We used thematic analysis to identify emerging themes.

RESULTS

Carers described initial surprise and then acceptance that agitation is a dementia symptom and learned to respond flexibly. Their strategies encompassed: prevention of agitation by familiar routine; reduction of agitation by addressing underlying causes and using distraction; prevention of escalation by risk enablement, not arguing; and control of their emotional responses by ensuring their relative's safety then walking away, carving out some time for themselves and using family and services for emotional and practical help.

CONCLUSIONS

These strategies can be manualised and tested in future randomised controlled trials for clinical effectiveness in reducing agitation in people with dementia living at home.

A meta-review of stress, coping and interventions in dementia and dementia caregiving

Background

There has been a substantial number of systematic reviews of stress, coping and interventions for people with dementia and their caregivers. This paper provides a meta-review of this literature 1988-2014.

Method

A meta-review was carried out of systematic reviews of stress, coping and interventions for people with dementia and their caregivers, using SCOPUS, Google Scholar and CINAHL Plus databases and manual searches.

Results

The meta-review identified 45 systematic reviews, of which 15 were meta-analyses. Thirty one reviews addressed the effects of interventions and 14 addressed the results of correlational studies of factors associated with stress and coping. Of the 31 systematic reviews dealing with intervention studies, 22 focused on caregivers, 6 focused on people with dementia and 3 addressed both groups. Overall, benefits in terms of psychological measures of mental health and depression were generally found for the use of problem focused coping strategies and acceptance and social-emotional support coping strategies. Poor outcomes were associated with wishful thinking, denial, and avoidance coping strategies. The interventions addressed in the systematic reviews were extremely varied and encompassed Psychosocial, Psychoeducational, Technical, Therapy, Support Groups and Multicomponent interventions. Specific outcome measures used in the primary sources covered by the systematic reviews were also extremely varied but could be grouped into three dimensions, viz., a broad dimension of “Psychological Well-Being v. Psychological Morbidity” and two narrower dimensions of “Knowledge and Coping” and of “Institutionalisation Delay”.

Conclusions

This meta-review supports the conclusion that being a caregiver for people with dementia is associated with psychological stress and physical ill-health. Benefits in terms of mental health and depression were generally found for caregiver coping strategies involving problem focus, acceptance and social-emotional support. Negative outcomes for caregivers were associated with wishful thinking, denial and avoidance coping strategies. Psychosocial and Psychoeducational interventions were beneficial for caregivers and for people with dementia. Support groups, Multicomponent interventions and Joint Engagements by both caregivers and people with dementia were generally found to be beneficial. It was notable that virtually all reviews addressed very general coping strategies for stress broadly considered, rather than in terms of specific remedies for specific sources of stress. Investigation of specific stressors and remedies would seem to be a useful area for future research.

Burden among male Alzheimer's caregivers: effects of distinct coping strategies

Focusing on the understudied, increasing population of male Alzheimer's disease (AD) caregivers, the purpose of this study was to identify their likelihood of utilizing 3 coping strategies (task focused, emotion focused, and avoidance focused) and to examine the effects of each coping strategy on caregiving burden. Data were collected from 138 male AD caregivers in southern United States, including geographically proportional representation of African Americans in the sample. Stepwise regression revealed effects of each coping strategy on caregiving burden, controlling for demographics. The sample reported high burden. Task focused was the highest reported coping strategy. Yet, regression models indicated no significant effect of task-focused coping on burden outcomes. Emotion-focused and avoidance-focused coping each showed significant proportional effects on burden. Implications suggest that emotion- and avoidance-focused coping among male AD caregivers may be maladaptive, that is, reinforcing burden. Male AD caregivers may benefit from more task-focused coping, such as planning and active problem solving.

Challenges in measuring outcomes for caregivers of people with mental health problems

Patient-reported outcomes (PROs) are increasingly important in health care and mental health research. Furthermore, caregivers become partners in care for patients with mental disorders, and health workers are more attentive to the expectations and needs of caregivers. A number of outcomes for caregivers are measured and used in daily practice in order to promote actions to improve health care systems and progress in research on the impact of mental disorders on their caregivers. This paper proposes an inventory of the different outcomes and different measurement tools used to assess the impact of disorders, raising a number of methodological and conceptual issues that limit the relevance of measurement tools and complicate their use. Finally, we propose some recommendations promoting the development of relevant outcome measures for caregivers and their integration into current systems of care.

Family carers' experiences of attending a multicomponent psychosocial intervention program for carers and persons with dementia

Background

Psychosocial interventions for persons with dementia and their primary family carers are promising approaches to reducing the challenges associated with care, but, obtaining significant outcomes may be difficult. Even though carers in general are satisfied with such interventions, few studies have evaluated the interventions by means of qualitative methods.

Aim

The objective of the study reported here was to investigate family carers’ experiences of a multicomponent psychosocial intervention program, and also to offer advice on how to develop the intervention program.

Methods

Content analyses were taken from individual qualitative interviews conducted in 2012 with 20 carers (aged 50–82 years) who participated in a psychosocial intervention program that included education, individual and family counseling, and parallel group sessions for carers and persons with dementia.

Results

Two main categories emerged: 1) benefits of the intervention program, which sets out the informants’ experiences for the benefits of participation, described in the subcategories “importance of content and group organization” and “importance of social support”; and 2) missing content in the intervention program, which details the informants’ suggestions for future interventions, contained in the subcategories “need for extended content” and “need for new group organization”.

Conclusion

The carers found the interventions useful. The importance of even earlier and more flexible interventions for the family carers, the extended family, and the persons with dementia was underscored.

Personality and dementia caring: a review and commentary

PURPOSE OF REVIEW

Carers of people with dementia are at increased risk of experiencing psychological distress. This article reviews recent findings on the role of personality traits for psychological outcomes for carers of people with dementia.

RECENT FINDINGS

Several studies have now established that personality influences the caregiving experience, carer well-being and outcomes such as coping ability, burden and caregiving style. Several moderators of these associations have also been identified such as the effect of kinship and type of dementia. There is consistent evidence that carer personality characteristics influence the progression of the disease such as cognitive decline and severity. Most of the recent studies identified in this review are cross-sectional.

SUMMARY

Taken together, these results indicate that personality is an important psychological resource for carers. Recent findings indicate that personality traits are associated with and influence both carer and patient outcomes. Future research is necessary to guide interventions and to expand further on our understanding of how personality factors shape adjustment to the caregiving role and how these impact on the progression of the disease.

Coping strategies as mediators of the effect of the START (strategies for RelaTives) intervention on psychological morbidity for family carers of people with dementia in a randomised controlled trial

BACKGROUND

Family carers of people with dementia frequently become depressed or anxious. In observational studies, more emotion-focused and less dysfunctional coping predict fewer psychological symptoms, but no randomised controlled trial (RCT) has directly investigated emotion-focused coping as mediator of effectiveness of a successful psychological intervention. We hypothesised that emotion-focused coping would mediate the START psychological intervention׳s effects in an RCT. We tested whether mediated effects were moderated by severity of baseline symptoms.

METHODS

260 family carers from NHS dementia services were randomised to START (manualised coping skills intervention), or treatment-as-usual (TAU). Blinded raters administered the Hospital Anxiety and Depression Scale (HADS-T) and Brief COPE inventory at baseline, 4 and 8 months. HADS-T improved in the intervention group when compared to TAU at all levels of psychological distress. We tested whether coping was a mediator and for moderated mediation, and (post-hoc) subgroup treatment effects on coping.

RESULTS

Data were available for 187 carers (71.9%) for the mediation analysis. The reduced HADS-T score in the intervention group was mediated by increased emotion-focused coping only among carers with higher (16+) baseline HADS-T scores (mediated effect=-0.63 [-1.11, -0.15]; proportion of overall effect=33% [3%, 64%]).

LIMITATIONS

We did not measure plausible psychosocial treatment mechanisms other than coping.

CONCLUSIONS

START benefited family carers both in preventing and treating psychological morbidity, through different mechanisms of action. The most psychologically distressed carers increased their emotion-focused coping and did not decrease their dysfunctional coping, while others benefited but not through this mechanism.

Caregiver burden and coping strategies in caregivers of patients with Alzheimer's disease

BACKGROUND

Alzheimer's disease (AD) causes considerable distress in caregivers who are continuously required to deal with requests from patients. Coping strategies play a fundamental role in modulating the psychologic impact of the disease, although their role is still debated. The present study aims to evaluate the burden and anxiety experienced by caregivers, the effectiveness of adopted coping strategies, and their relationships with burden and anxiety.

METHODS

Eighty-six caregivers received the Caregiver Burden Inventory (CBI) and the State-Trait Anxiety Inventory (STAI Y-1 and Y-2). The coping strategies were assessed by means of the Coping Inventory for Stressful Situations (CISS), according to the model proposed by Endler and Parker in 1990.

RESULTS

The CBI scores (overall and single sections) were extremely high and correlated with dementia severity. Women, as well as older caregivers, showed higher scores. The trait anxiety (STAI-Y-2) correlated with the CBI overall score. The CISS showed that caregivers mainly adopted task-focused strategies. Women mainly adopted emotion-focused strategies and this style was related to a higher level of distress.

CONCLUSION

AD is associated with high distress among caregivers. The burden strongly correlates with dementia severity and is higher in women and in elderly subjects. Chronic anxiety affects caregivers who mainly rely on emotion-oriented coping strategies. The findings suggest providing support to families of patients with AD through tailored strategies aimed to reshape the dysfunctional coping styles.

Relationship of coping style to mood and anxiety disorders in dementia carers

PURPOSE OF REVIEW

Mood and anxiety disorders are common in family carers of people with dementia, and are associated with poor carer and care recipient outcomes. Caring for someone with dementia is stressful, but how carers cope may be an important determinant of carer psychological morbidity. This review summarizes and integrates the literature on the effect of coping style and its role in effective carer interventions.

RECENT FINDINGS

Two systematic reviews evaluated relationships between coping style and mood/anxiety disorders in observational studies and randomized controlled trials (RCTs), respectively. Several subsequent cross-sectional studies have also investigated these relationships, including in the context of coping as a mediator or moderator. Studies also investigated suicidality and cultural factors underlying coping.

SUMMARY

More dysfunctional, and less emotional support and acceptance-based coping styles are robustly associated with carer depression and anxiety symptoms and caseness in cross-sectional studies. There is also preliminary evidence from longitudinal studies that these coping styles may predict subsequent carer psychological morbidity. Psychological interventions successful in reducing depression counterintuitively increased dysfunctional coping in RCTs, but no RCTs have directly tested whether emotional support and acceptance-based coping mediates the effects of psychological intervention.

The effect of psychosocial support intervention on depression in patients with dementia and their family caregivers: an assessor-blinded randomized controlled trial

Background/Aim

A three-component tailored psychosocial 12-month assessor-blinded randomized controlled trial to reduce depression in people with dementia (PWD) and carers was conducted.

Methods

A total of 230 home-dwelling dyads of PWD and their carers were randomized to usual care or intervention consisting of three components over 12 months. Primary outcomes were the difference between the baseline and 12-month score on the Cornell Scale of Depression in Dementia (CSDD) in the PWD and on the Geriatric Depression Scale (GDS) in the carers.

Results

The intent-to-treat difference between the baseline and 12-month change score was not significant between the intervention and control groups for the CSDD (p = 0.95) or GDS (p = 0.82).

Conclusions

The trial did not show a significant difference between usual care and the intervention on depressive symptoms in PWD or their family caregivers.
