Effects of two caregiver-training programs on burden and attitude toward help

Caregiving setting and Baby Boomer caregiver stress processes: Findings from the National Study of Caregiving (NSOC)

The aim of this study was to provide a comprehensive understanding of how the caregiving setting relates to caregiving experience among Baby Boomer caregivers (CGs). Based on a secondary data analysis (the National Study of Caregiving, N = 782), compared with CGs providing care to an older adult living in the community, CGs to older adults in non-NH residential care settings reported better emotional well-being, self-rated health, and relationship quality and less provision of assistance older adults with daily activities. While chronic conditions, relationship quality, and financial strain were associated with the health and well-being for both CG groups, degree of informal support was more consequential for the health of CGs providing care to older adults in the community. Our results provide critical information on the risk factors and areas of intervention for both CG groups.

Predictors of Use of Services Among Dementia Caregivers

Caregivers of persons with dementia do not use community resources until late in the disease process, despite the fact that judicious use of community resources can delay nursing home admission. Data from the National Caregiver Training Project, based on Hall and Buckwalter’s (1987) progressively lowered stress threshold (PLST) model, were used to examine variables related to use of community resources. Spouse and adult child caregivers were divided into two groups based on amount of community resources used per week. Within this geographically diverse sample of caregivers, 64% did not use professional services, 79% did not use respite services, and 65% did not use other services. Being a spouse decreased the odds that the caregiver would use community resources. Resource use was also related to the care recipient’s problems with activities of daily living and the increase in frequency of memory and behavioral problems.

Rural Stroke Caregivers: A Qualitative Study of the Positive and Negative Response to the Caregiver Role

Caregivers are often referred to as the "hidden patients." Rarely has caregiving research focused on the positive aspects of caregiving. The purpose of this study was to investigate the lived experiences of caregivers of stroke survivors who have been in the caregiver role for at least 6 months poststroke. The conceptual framework was based on a combination of Lazarus' stress and coping theory and Weiner's attribution theory. A qualitative cross-sectional design was employed. It involved a sample of 10 caregivers from a rural county in Wyoming. A total of 24 categories were identified and five themes emerged: (1) a sense of loyalty; (2) acceptance; (3) a sense of "feeling good"; (4) satisfaction is associated with helping others; and (5) burden is associated with lifestyle change. Participants in this study reported several positive outcomes as well as some negative outcomes in regard to their role as caregivers.

Functional analysis-based interventions for challenging behaviour in dementia

BACKGROUND

Functional analysis (FA) for the management of challenging behaviour is a promising behavioural intervention that involves exploring the meaning or purpose of an individual's behaviour. It extends the 'ABC' approach of behavioural analysis, to overcome the restriction of having to derive a single explanatory hypothesis for the person's behaviour. It is seen as a first line alternative to traditional pharmacological management for agitation and aggression. FA typically requires the therapist to develop and evaluate hypotheses-driven strategies that aid family and staff caregivers to reduce or resolve a person's distress and its associated behavioural manifestations.

OBJECTIVES

To assess the effects of functional analysis-based interventions for people with dementia (and their caregivers) living in their own home or in other settings.

SEARCH METHODS

We searched ALOIS: the Cochrane Dementia and Cognitive Improvement Group's Specialized Register on 3 March 2011 using the terms: FA, behaviour (intervention, management, modification), BPSD, psychosocial and Dementia.

SELECTION CRITERIA

Randomised controlled trials (RCTs) with reported behavioural outcomes that could be associated with functional analysis for the management of challenging behaviour in dementia.

DATA COLLECTION AND ANALYSIS

Four reviewers selected trials for inclusion. Two reviewers worked independently to extract data and assess trial quality, including bias. Meta-analyses for reported incidence, frequency, severity of care recipient challenging behaviour and mood (primary outcomes) and caregiver reaction, burden and mood were performed. Details of adverse effects were noted.

MAIN RESULTS

Eighteen trials are included in the review. The majority were in family care settings. For fourteen studies, FA was just one aspect of a broad multi-component programme of care. Assessing the effect of FA was compromised by ill-defined protocols for the duration of component parts of these programmes (i.e. frequency of the intervention or actual time spent). Therefore, establishing the real effect of the FA component was not possible.Overall, positive effects were noted at post-intervention for the frequency of reported challenging behaviour (but not for incidence or severity) and for caregiver reaction (but not burden or depression). These effects were not seen at follow-up.

AUTHORS' CONCLUSIONS

The delivery of FA has been incorporated within wide ranging multi-component programmes and study designs have varied according to setting - i.e. family care, care homes and hospital, with surprisingly few studies located in care homes. Our findings suggest potential beneficial effects of multi-component interventions, which utilise FA. Whilst functional analysis for challenging behaviour in dementia care shows promise, it is too early to draw conclusions about its efficacy.

Cognitive reframing for carers of people with dementia

BACKGROUND

The balance of evidence about whether psychosocial interventions for caregivers of people with dementia could reduce carers' psychological morbidity and delay their relatives' institutionalisation is now widely regarded as moderately positive (Brodaty 2003; Spijker 2008). Multi-component, tailor-made psychosocial interventions are considered to be particularly promising (Brodaty 2003; Spijker 2008). These interventions involve multiple mechanisms of action. In this review we focused solely on the effectiveness of one element within psychosocial interventions, cognitive reframing. Cognitive reframing is a component of cognitive behavioral therapy (CBT). In dementia care, cognitive reframing interventions focus on family carers' maladaptive, self-defeating or distressing cognitions about their relatives' behaviors and about their own performance in the caring role.

OBJECTIVES

The objective of this review was to evaluate the effectiveness of cognitive reframing interventions for family carers of people with dementia on their psychological morbidity and stress.

SEARCH METHODS

The trials were identified by searching (5 April 2009) the Cochrane Dementia and Cognitive Improvement Group Specialized Register, which contains records from major healthcare databases: The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL and LILACS, ongoing trial databases and grey literature sources. For more detailed information on what the Group's specialized register contains and to view the search strategies see the Cochrane Dementia and Cognitive Improvement Group methods used in reviews.The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL, LILACS and a number of trial registers and grey literature sources were also searched separately on 5 April 2009.

SELECTION CRITERIA

Randomised controlled trials of cognitive reframing interventions for family carers of people with dementia.

DATA COLLECTION AND ANALYSIS

Three assessors (MVD, ID, JmC) independently judged whether the intervention being studied was documented in a trial; two assessors assessed trial quality.

MAIN RESULTS

Pooled data indicated a beneficial effect of cognitive reframing interventions on carers' psychological morbidity, specifically anxiety (standardised mean difference (SMD) -0.21; 95% confidence interval (CI) -0.39 to -0.04), depression (SMD -0.66; 95% CI -1.27 to -0.05), and subjective stress (SMD -0.23; 95% CI -0.43 to -0.04). No effects were found for carers' coping, appraisal of the burden, reactions to their relatives' behaviors, or institutionalization of the person with dementia.

AUTHORS' CONCLUSIONS

Cognitive reframing for family carers of people with dementia seems to reduce psychological morbidity and subjective stress but without altering appraisals of coping or burden. The results suggest that it may be an effective component of individualised, multi-component interventions for carers. Identifying studies with relevant interventions was a challenge for this review. The impact of cognitive reframing might be higher when used alongside other interventions because this offers better opportunities to tailor cognitive reframing to actual everyday carer problems.

Systematic review of the effect of psychological interventions on family caregivers of people with dementia

BACKGROUND

Caregivers of people with dementia are at high risk of psychological morbidity and associated breakdown in care. Many psychologically based interventions have been designed to help caregivers of people with dementia. More work is needed to identify which, if any, are helpful for such caregivers.

METHOD

We conducted a systematic review of the immediate and long term efficacy of different types of psychological interventions for the psychological health of caregivers of people with dementia, using standardized criteria, to assist clinicians in implementing rational, evidence-based management recommendations. We reviewed studies examining the effects of any therapy derived from a psychological approach that satisfied pre-specified criteria. Using the Oxford Centre for Evidence-Based Medicine criteria we rated the quality of each study, extracted data and gave overall ratings to different types of intervention.

RESULTS

We identified 244 references in our search of which 62 met our inclusion criteria.

LIMITATIONS

Our findings are limited by lack of good quality evidence, with only ten level 1 studies identified.

CONCLUSIONS

We found excellent evidence for the efficacy of six or more sessions of individual behavioral management therapy centered on the care recipient's behavior in alleviating caregiver symptoms both immediately and for up to 32 months. Teaching caregivers coping strategies either individually or in a group also appeared effective in improving caregiver psychological health both immediately and for some months afterwards. Group interventions were less effective than individual interventions. Education about dementia by itself, group behavioral therapy and supportive therapy were not effective caregiver interventions.

Is it beneficial to involve a family member? A meta-analysis of psychosocial interventions for chronic illness

Links between chronic illness and family relationships have led to psychosocial interventions targeted at the patient's closest family member or both patient and family member. The authors conducted a meta-analytic review of randomized studies comparing these interventions with usual medical care (k=70), focusing on patient outcomes (depression, anxiety, relationship satisfaction, disability, and mortality) and family member outcomes (depression, anxiety, relationship satisfaction, and caregiving burden). Among patients, interventions had positive effects on depression when the spouse was included and, in some cases, on mortality. Among family members, positive effects were found for caregiving burden, depression, and anxiety; these effects were strongest for nondementing illnesses and for interventions that targeted only the family member and that addressed relationship issues. Although statistically significant aggregate effects were found, they were generally small in magnitude. These findings provide guidance in developing future interventions in this area.

Guidelines for the Treatment of Alzheimer??s Disease from the Italian Association of Psychogeriatrics

A committee of experts from the Italian Association of Psychogeriatrics compiled the following report, which was then approved by a Steering Committee (comprising 20 specialists in neurology, psychiatry or geriatrics) from the Association and by two Alzheimer associations representing patients and families: the Italian Association for Alzheimer's Disease and the Italian Federation for Alzheimer's Disease. The report is based on a comprehensive review of the scientific literature on the treatment of Alzheimer's disease, discusses methodological aspects of dementia management, and details the limitations of current therapies. These guidelines are, in general, consistent with the principles of evidence-based medicine; however, for some controversial or poorly investigated issues, the guidelines integrate scientific evidence with experience and opinions from experts working in the clinical setting. In particular, the clinical experience of experts has been used to define recommendations for starting and interrupting pharmacotherapy, and to critically review evidence about the efficacy of non-pharmacological interventions. The principal pharmacotherapeutic interventions covered in the guidelines are acetylcholinesterase inhibitors (donepezil, galantamine, rivastigmine, and tacrine) and memantine. The main non-pharmacological interventions reviewed are memory training, reality orientation therapy, and combined non-pharmacological interventions. Other issues covered are opportunities for Alzheimer's disease prevention, various modalities of care, and the treatment of comorbidities.

The Effect of a Structured Intervention on Caregivers of Patients With Dementia and Problem Behaviors

The objective was to assess the effect of a structured intervention on caregiver stress and the institutionalization rate of patients with dementia and problem behaviors. Caregivers contacting the Federazione Alzheimer Italia (AI) to receive help, advice, or information in relation to problem behaviors of outpatients were enrolled. Eligible caregiver-patient dyads were randomized to receive either a structured intervention or the counseling AI usually provides (control group). After basal assessment, families were reassessed at 6 and 12 months. Problem behavior (particularly agitation) was the only variable significantly correlated (P = 0.006) with the baseline caregivers' stress score. Thirty-nine families completed the 12-month follow-up; the mean problem behavior score was significantly lower in the intervention than the control group (p < 0.03); the time needed for care of the patient increased by 0.5 +/- 9.7 hours/day in the control group and decreased by 0.3 +/- 4.1 in the intervention group (p = 0.4, Wilcoxon test). The main determinant of institutionalization seemed to be the level of caregiver stress (p = 0.03). In patients of the intervention group, there was a significant reduction in the frequency of delusions. This pilot study suggests that caregiver stress is relieved by a structured intervention. The number of families lost to follow-up, the relatively short duration of the study, and the ceiling effect due to the severity of the clinical characteristics of patients probably all partly dilute the observed findings.

Meta-analysis of psychosocial interventions for caregivers of people with dementia

OBJECTIVES

To review published reports of interventions for caregivers (CGs) of persons with dementia, excluding respite care, and provide recommendations to clinicians.

DESIGN

Meta-analytical review. Electronic databases and key articles were searched for controlled trials, preferably randomized, published in English from 1985 to 2001 inclusive. Thirty studies were located and scored according to set criteria, and the interventions' research quality and clinical significance were judged.

SETTING

Home or noninstitutional environment.

PARTICIPANTS

Informal CGs-persons providing unpaid care at home or in a noninstitutional setting.

MEASUREMENTS

The primary measures were psychological morbidity and burden. Other varied outcome measures such as CG coping skills and social support were combined with measures of psychological distress and burden to form a main outcome measure.

RESULTS

The quality of research increased over the 17 years. Results from 30 studies (34 interventions) indicated, at most-current follow-up, significant benefits in caregiver psychological distress (random effect size (ES) = 0.31; 95% confidence interval (CI) = 0.13-0.50), caregiver knowledge (ES = 0.51; CI = 0.05-0.98), any main caregiver outcome measure (ES = 0.32; CI = 0.15-0.48), and patient mood (ES = 0.68; CI = 0.30-1.06), but not caregiver burden (ES = 0.09; CI = -0.09-0.26). There was considerable variability in outcome, partly because of differences in methodology and intervention technique. Elements of successful interventions could be identified. Success was more likely if, in addition to CGs, patients were involved. Four of seven studies indicated delayed nursing home admission.

CONCLUSION

Some CG interventions can reduce CG psychological morbidity and help people with dementia stay at home longer. Programs that involve the patients and their families and are more intensive and modified to CGs' needs may be more successful. Future research should try to improve clinicians' abilities to prescribe interventions.

Caregiver education and support: results of a multi-site pilot in an HMO

Caregiver workshops were offered to members by a group practice HMO as part of a larger demonstration of adding community care to HMO services. Of 1,200 members indicating interest at four sites, 532 participated in workshops and 320 completed pre- and post-questionnaires on effectiveness. Analyses showed improvements in caregiving preparedness and reductions in sadness and depression. Engagement in the workshops (completing 3 or more sessions) and improvements were more likely for individuals with more independent lives and social capital. Alternative helping strategies are recommended for caregivers who are less likely to engage in classes due to burden or lack of respite or transportation.

Burden on family members: caring for frail elderly: a meta-analysis of interventions

BACKGROUND

Although multiple interventional approaches to reduce perceived burden among caregivers of the frail elderly have been investigated for over a decade, the effectiveness of those interventions and the benefits of group versus individual interventions are largely unclear.

OBJECTIVES

This meta-analysis was undertaken to (a) assess the effectiveness of group and individual interventions on decreasing burden of caregivers of the frail elderly, and (b) identify factors with potential influence on the magnitude of the effects.

METHOD

Computerized literature searches and manual searches of published true and quasi-experimental studies with control groups were performed. A coding form was developed to record methodological and other study characteristics, including study design, attrition rate, and reliability and validity of the measures.

RESULTS

Eighteen group and eight individual interventional studies published from 1985 to 2000 were included. For group interventions, the sample size for individual studies ranged from 20 to 486, with a total of 1,970. The weighted mean effect size was 0.41 (95% CI: 0.32 to 0.51), indicating a significant positive treatment effect. A significant homogeneity test (Q(17) = 56.37, p <.0001) indicated that there were variations in effect sizes among the studies attributable to study characteristics. The effect size in the 11 true experimental studies was smaller (M: 0.26, 95% CI: 0.15 to 0.37) but still existed. For individual interventions, the sample sizes ranged from 16 to 168, with a total of 472. The weighted effect sizes were homogeneous with a mean of 0.48 (95% CI: 0.30 to 0.67), indicating a positive treatment effect.

DISCUSSION

Available evidence supports the premise that both group and individual interventions reduce perceived burden, however, this evidence is inconclusive. Further studies of large scale and high quality designs are needed.

Problem behaviour, caregiver reactions, and impact among caregivers of persons with Alzheimer's disease

BACKGROUND

Problem behaviours that occur during Alzheimer's disease (AD) can have major impact on caregivers. How caregivers react to these behaviours may determine the total impact experienced from caregiving.

PURPOSE

This study examined the relationships between problematic behaviours and caregiving impact in 30 primary caregivers of persons with AD. The first question explored the relationship between frequency of problem behaviour and impact; the second explored the relationship between caregiver reactions to problem behaviours and impact from caregiving.

METHODS

The frequency of problem behaviour and the caregiver reaction was measured using The Revised Memory and Behaviour Problem Checklist (Teri et al. 1992). The impact from caregiving was operationalized using the Cost of Care Index developed by Kosberg and Cairl (1986).

RESULTS

Significant associations were found for 11 of the 20 subscales that measured the association between the frequency of problem behaviour in the client and the impact from caregiving experienced by the caregiver. In comparison, the association between caregiver's reaction to problem behaviours and impact from caregiving was even more significant in value with 15 subscales of 20 being significant. Female caregivers experienced a greater reaction to disruptive and depressive behaviour when compared with male caregivers even though both genders reported similar frequencies of problem behaviours. In regard to findings about the impact from caregiving, four of the six indicators were higher for women than for men.

CONCLUSIONS

Caregiver reaction to problem behaviours was more highly associated with impact from caregiving than the actual frequency of the behaviours. These findings have great implications for intervention programs. Caregivers, especially females, need to receive individualized, specific education/training on how to understand and manage disruptive and depressive behaviour in persons with AD.

Interventions to reduce the burden of caregiving for an adult with dementia: a meta-analysis

Because of conflicting results, in order to clarify the state of the science it was necessary to do a systematic analysis of the literature on research testing the effect of interventions on the burden of persons caring for family members with dementia. The purpose of this study was to evaluate, using meta-analytic techniques, those intervention strategies (support group, education, psychoeducation, counseling, respite care, and multicomponent) designed to help caregivers cope with the burden of caregiving. Using meta-analytic methods developed by Glass, McGraw, and Smith (1981) and Hedges and Olkin (1985), 24 published research reports testing 27 treatments for caregivers of adults with dementia were synthesized. Overall, the analysis showed that collectively the interventions had no effect on caregiver burden. Only the category of multicomponent interventions significantly reduced caregiver burden. Burden may be too global an outcome to be affected consistently by intervention. Better and more precise measures are needed to evaluate the effects of caregiver interventions properly.

A systematic review of the effectiveness of psychosocial interventions for carers of people with dementia

Historically, there have been many attempts to develop interventions to support the carers of people with dementia. To date the evidence of effectiveness has been limited. However, the success of psychosocial interventions for carers of people with schizophrenia has suggested the possibility of utilizing this approach. A systematic review was undertaken to assess the evidence of effectiveness for psychosocial interventions with carers of people with dementia. Thirty controlled trials that evaluated a psychosocial approach were identified. The overall methodological quality of these studies was poor, particularly with regard to sample size, and methods of random allocation. Individualized interventions that utilized problem solving and behaviour management demonstrated the best evidence of effectiveness. This approach is also closest to the effective model of psychosocial interventions currently in use with other severe and enduring illnesses. This suggests that there is scope for developing interventions, based more specifically on this model, for supporting the carers of people with dementia.

Support for carers of people with Alzheimer's type dementia

BACKGROUND

Research has highlighted the problems for carers of people with dementia. These include the effective loss of companionship and support of a life partner, social isolation and complex financial, legal and social decision making. The burden of caring is financially, emotionally and physically significant. Studies of the effects of ways of supporting carers and reducing the burden of caring often examine a range of outcomes. Probably because of these characteristics, no formal overview of this area of service provision has been undertaken. Moreover, the term 'intervention' in relation to caregivers of people with Alzheimer's disease is open to wide variations in interpretation at the level of service provision. Interventions range from the application of 'hi-tech' computer technology for socialy isolated carers, to the formation of specialist support groups and respite services.

OBJECTIVES

The objective of this review is to provide an assessment of the effectiveness of health and/or social interventions designed to help support the carers of people with Alzheimer's-type dementias.

SEARCH STRATEGY

The Cochrane Controlled Trials Register was searched using the terms 'carer*' and 'caregiv*'. See the Cochrane Dementia & Cognitive Impairment group's details for the full search strategy.

SELECTION CRITERIA

All randomised trials in which primary carers of people with Alzheimer's disease are allocated to either intervention or non-intervention/control groups and where the intervention was provided by healthcare and/or social services.

DATA COLLECTION AND ANALYSIS

Data was extracted by both reviewers and was found to be unsuitable for quantitative synthesis. A qualitative overview is presented and structured according to the comparisons used in the review. Weighted Mean Differences (weighted by sample size) for each outcome and its subcategories are also presented.

MAIN RESULTS

The results of the review are inconclusive. No evidence was found for the following comparison interventions: 1) individualised service assessment and planning versus conventional support 2) technology-based carer networking (via computers or telephones) versus conventional support 3) carer-education/training versus conventional support 4) multi-faceted/dimensional strategies (such as specialised carer assessment and training) versus conventional support Whilst the overview suggests little or no evidence that interventions to support caregivers of people with Alzheimer's disease are of quantifiable benefit, the poor quality and small sample sizes of the studies, as well as the diversity of interventions examined and outcomes reported, mean that this conclusion cannot be put forward without the need for caution, particularly as some of the studies put forward qualitative evidence which contradicts this conclusion.

REVIEWER'S CONCLUSIONS

With the limited nature of the research evidence in mind, it is not possible to recommend either wholesale investment in caregiver support programmes or withdrawal of the same. With the addition of further studies in future updates of this review, expected in early 1999, this presently inconclusive picture may become clearer. A number of conclusions relating to future areas of research can be put forward with more conviction. Specifically, 1) Future trials need to examine interventions included in the existing knowledge base on Alzheimer's carer-supportive interventions. 2) Outcome measures used should mirror those in similar studies. 3) Outcome measures need to be clinically and 'lay' relevant. 4) Trials need to be of longer duration given the 7-10 years median life expectancy of people with Alzheimer's Disease. 5) Sample sizes need to be increased and calculated properly given the likelihood of a moderate intervention effect (if any). 7) Blinding at the outcome assessment stage needs to be a part of future basic trial designs if bias is to be avoided. 8) If reviews are to have their power increased then quality o
