Recurrent depressive symptomatology and physical health: a 10-year study of informal caregivers of persons with dementia

Positive aspects of caregiving attenuate the relationship between behavioral bother and anxiety and depressive symptoms in dementia family caregivers

AIM

To examine the protective role of positive aspects of caregiving (PAC) in terms of whether it dampens the relationship between behavioral bother and anxiety/depressive symptoms.

METHODS

The baseline data of the Resources for Enhancing Alzheimer's Caregiver Health I trial were used. US dementia family caregivers (N = 1222) responded to standard self-report measures of PAC, behavioral bother, depression, anxiety, challenging behaviors, and functional impairment. The buffering effect of PAC was tested using moderational regression.

RESULTS

Controlling for caregivers' age, sex and behavioral bother, and care-recipients' challenging behaviors and functional impairment, PAC was mildly inversely related to depressive and anxiety symptoms. Moreover, a significant PAC × behavioral bother interaction effect was found such that the relationship between behavioral bother, on the one hand, and depression and anxiety, on the other, became weaker with higher PAC. In particular, when behavioral bother was low, depressive and anxiety symptoms were similar regardless of levels of PAC. But when behavioral bother was high, caregivers who reported higher levels of PAC were less depressed and anxious than those with lower levels, with their standardized mean differences being small to moderate.

CONCLUSIONS

PAC was found to be associated with less mood symptoms partly directly and partly through modifying the effect of behavioral bother on depression and anxiety. Caregivers who were highly troubled by the relative's challenging behaviors, but who found higher levels of PAC at the same time, experienced better emotional well-being. Having PAC may make the burden of caregiving more tolerable, thereby alleviating caregiver distress down the road. Geriatr Gerontol Int 2023; 23: 366-370.

Are Care-Recipient Outcomes Attributable to Improved Caregiver Well-Being? A Cluster-Randomized Controlled Trial of Benefit-Finding Intervention

OBJECTIVES

The benefit-finding therapeutic (BFT) intervention, training cognitive reappraisal, and alternative thinking to construct positive aspects of caregiving have been found to reduce caregiver depression. This study examines BFT effects on care-recipient outcomes via reduced caregiver depression.

DESIGN

Cluster-randomized double-blind controlled trial.

SETTING

Social centers and clinics.

PARTICIPANTS

A total of 129 caregivers. Inclusion criteria were 1) primary caregiver aged 18+, 2) without cognitive impairment, 3) providing ≥14 care hours weekly to a relative with mild-to-moderate Alzheimer's disease, and 4) scoring ≥3 on the Hamilton Depression Rating Scale. Exclusion criterion was care-recipient having Parkinsonism or other forms of dementia.

INTERVENTIONS

BFT was evaluated against two forms of psychoeducation-standard and simplified (lectures only) psychoeducation.

MEASUREMENTS

Care-recipient outcomes included neuropsychiatric symptoms (NPS), functional impairment, and global dementia severity (Clinical Dementia Rating sum-of-box), measured at baseline, postintervention, and 4- and 10-month follow up.

RESULTS

Mixed-effects regressions showed a significant effect on NPS when compared with simplified psychoeducation only, with BFT participants reporting fewer NPS (especially mood symptoms) at 4-month follow-up (d = -0.52). Furthermore, longitudinal path analysis (using changes in caregiver depression scores at postintervention to predict changes in care-recipient NPS at follow-up) found that this effect was mediated by improved caregiver depression. No other intervention or mediation effects were found or were consistent across analyses.

CONCLUSIONS

Less depressed caregivers may be able to provide better care and more positive interactions, leading to reduced NPS in care-recipients. However, this benefit of BFT was limited to the comparison with simplified psychoeducation only.

Depression But Not Inflammatory Markers Are Increased in Family Versus Nonfamily Caregivers of Persons With Dementia

We investigated quality of life (WHOQoL-BREF), perceived stress (PSS-10), anxiety and depression (HADS-M), life satisfaction (SWLS), and serum levels of interleukin-6 (IL-6), C-reactive protein (CRP), and cortisol in family caregivers (n = 94) and professional caregivers (n = 48) of demented patients, as well as among noncaregivers (n = 30). Compared with professional caregivers, family caregivers had higher scores in HADS-M depression (P = .003) and anxiety (P = .033), lower life satisfaction (P = .04), and lower quality of life in psychological (P = .02) and social relationship (P = .03) domains. There were no differences in serum levels of IL-6, CRP, or cortisol between caregivers and control participants. In multivariable analysis, when family relationship was considered together with the time period of caregiving and results of the Mini-Mental State Examination test in care recipients (n = 118, 12.49 ± 7.99), only family relationship influenced scores in HADS-M depression (P = .004), SWLS scores (P = .011), and WHOQoL-BREF scores in psychological (P = .011) and social relationship (P = .008) domains. In conclusion, family caregivers are more stressed and have deeper depressive and anxiety disorders, lower life satisfaction, and lower quality of life than professional caregivers.

What is an older husband's experience of caring for his wife who has dementia?

A significant number of informal carers look after people who have dementia. Women's caring experiences are well documented. However, a substantially smaller amount of research exists specifically investigating the male carer perspective. This literature review explores older husbands' experiences of caring for their wives who have dementia. The findings suggest that husbands are committed to their caring role but can feel socially isolated. The caring role of older men has altered the dynamic in the marriage. Husbands continue to show commitment towards their spouses but feel that male-only support groups could offer some respite from their responsibilities. Nurses need to take time to listen to husbands' experiences, offering emotional support and signposting them to other services. Further research on the long-term effects and support needs of older male carers is needed.

Quality of life of family carers of persons with young-onset dementia: A Nordic two-year observational multicenter study

OBJECTIVES

To identify factors associated with QOL in carers of persons with young-onset Alzheimer's (AD) and frontotemporal dementia (FTD) and explore development in QOL over a two-year period.

METHODS

Eighty-eight family carers of community-dwelling people with young-onset AD (n = 50) and FTD (n = 38) recruited from Nordic memory clinics. Carer QOL was assessed using the Quality of Life-Alzheimer's Disease questionnaire. Carer burden was assessed by the Relatives' Stress scale and depressive symptoms by the Montgomery-Åsberg Depression Rating Scale. Factors associated with QOL in YOD and development in QOL over time were explored with growth mixture model trajectories and mixed model analyses.

RESULTS

We identified two carer groups of persons with YOD following trajectories with better (n = 53) versus poorer (n = 30) QOL. Carers who reported more burden at baseline had greater odds of belonging to the poorer QOL group (OR 1.1 (1.0-1.2), p = 0.004). Analyses of the development in QOL showed a significant decline in QOL-AD scores among the AD-carers from baseline to two-year follow-up (p = 0.044), while the score remained stable among the FTD-carers. The FTD-carer group had significantly higher mean QOL-AD scores at one- and two-year follow-up (p = 0.022 and 0.045, respectively). However, the difference between the two groups regarding time trend was non-significant. Poorer QOL was associated with increased carer burden (p = 0.01), more depressive symptoms (p = 0.024), and being male carer (p = 0.038).

CONCLUSION

Higher care burden, more depressive symptoms, and being a male carer was associated with poorer QOL in family carers for persons with YOD. Carers of persons with AD may experience greater challenges in preserving QOL compared to carers of persons with FTD.

Caregiving in Dementia and its Impact on Psychological Functioning and Health-Related Quality of Life: Findings from a Colombian Sample

Existing published studies about health-related quality of life (HRQOL) in caregivers of dementia patients living in Latin American countries are very limited. However, cultural aspects, personal values, and social structure may affect the way caregivers experience their role in different societies. The current study investigated the relationship between HRQOL and psychological factors using a cross-sectional design. The sample consisted of 102 informal caregivers of patients with dementia from Bogotá, Colombia, South America. Measures included the Patient Health Questionnaire (PHQ-9) for depression, the Satisfaction with Life Scale (SWLS), the Zarit Burden Interview, and the Short Health Questionnaire (SF36) for HRQOL. Canonical correlations revealed that there was a significant relationship between caregivers' mental health and HRQOL, such that caregivers with better satisfaction with life and less symptoms of depression had more vitality and better general health. There is a strong relationship between mental health and health-related quality of life in Colombian caregivers of dementia patients living in their country of origin. Specific aspects of mental health, including satisfaction with life and depression, need to be addressed in order to improve caregivers' quality of life. Given that mental health care resources may be scarce in Latin American countries, culturally appropriate interventions should focus on preventing/treating depression and promote life satisfaction, as a way to improve their quality of life.

Effectiveness of a psychoeducational intervention group program in the reduction of the burden experienced by caregivers of patients with dementia: the EDUCA-II randomized trial

We conducted a multicenter, prospective, evaluator-blinded, 2-arm parallel randomized trial to compare the effectiveness of a group psychoeducational intervention (PIP) with that of standard care in dementia caregivers. The primary outcome was the burden experience evaluated by the Zarit Burden Interview. Secondary outcomes were psychological distress evaluated with the scaled General Health Questionnaire-28 items, and quality of life evaluated with the Short-Form Health Survey 12. Effectiveness endpoint was at 4 months since inception. Statistical analyses used complete case and intention-to-treat analysis (ITT). The trial recruited 238 caregivers from 22 research sites (115 randomized to PIP, 123 randomized to standard care). No differences were found in the Zarit Burden Interview scores (complete case analysis: mean difference=-1.02, 95% confidence interval=-4.41 to 2.37; ITT analysis: MD=-0.55, 95% confidence interval=-3.64 to 2.55), the Short-Form Health Survey 12 domain scores (all P>0.05), and total General Health Questionnaire-28 items scores and some of its subscales (all P>0.05) except the anxiety and insomnia subscale for the ITT analysis (P=0.03). In summary, PIP in modality of group intervention was not better than standard care to reduce caregiver burden and overall psychological distress or to improve quality-of-life domains.

Applying Risk Society Theory to findings of a scoping review on caregiver safety

Chronic Illness represents a growing concern in the western world and individuals living with chronic illness are primarily managed at home by family caregivers. A scoping review of the home-care literature (2004-2009; updated with review articles from 2010 to January 2013) on the topic of the caregiver revealed that this group experiences the following safety-related concerns: caregivers are conscripted to the role, experience economic hardship, risk being abused as well as abusing, and may well become patients themselves. Methodology and methods used in the scoping review are presented as well as a brief overview of the findings. The concepts of risk and safety are defined. Risk Society Theory is introduced and used as a lens to view the findings, and to contribute to an understanding of the construction of risk in contemporary health-care.

Effect of the Act on Promotion of Personal Autonomy and Care for dependent persons on their family caregivers

Background

The need of home care services is becoming an increasingly common scenario. These cares are mainly provided by the dependents’ relatives specifically, by the women part of the family. This situation might take years, decreasing the physical and psychological health of the caregiver. In Spain, the Act of Promotion of Personal Autonomy and Care for dependent persons, guarantees those dependent persons and their caregivers to have access to social services or to financial grants. The aim of this study is to Know the possible effects of the benefits provided by this Act in regards to the mental health, the quality of life and use of health services by the family caregivers assisting their relatives in situation of dependency.

Methods and design

A longitudinal descriptive study following-up a cohort of patients and caregivers. The study shall be carried out in Andalusia. It shall include the baseline assessment of the variables in those caregivers free from the exposure factor (reception of assistance pursuant to the Act). Following, once the benefits have been received, this cohort shall be followed-up.

The study shall take three years, and the starting date for its development as well as its funding is January 2011.

Discussion

The longitudinal assessment of the rate of change of the variables studied shall allow us to know the implications which might be potentially generated as well as the natural evolution of those.

Predictors of dementia caregiver depressive symptoms in a population: the Cache County dementia progression study

OBJECTIVES

Previous research has consistently reported elevated rates of depressive symptoms in dementia caregivers, but mostly with convenience samples. This study examined rates and correlates of depression at the baseline visit of a population sample of dementia caregivers (N = 256).

METHOD

Using a modified version of Williams (Williams, I. C. [2005]. Emotional health of black and white dementia caregivers: A contextual examination. The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences, 60, P287-P295) ecological contextual model, we examined 5 contexts that have contributed to dementia caregiver depression. A series of linear regressions were performed to determine correlates of depression.

RESULTS

Rates of depressive symptoms were lower than those reported in most convenience studies. We found fewer depressive symptoms in caregivers with higher levels of education and larger social support networks, fewer health problems, greater likelihood of using problem-focused coping, and less likelihood of wishful thinking and with fewer behavioral disturbances in the persons with dementia.

DISCUSSION

These results suggest that depression may be less prevalent in populations of dementia caregivers than in clinic-based samples, but that the correlates of depression are similar for both population and convenience samples. Interventions targeting individuals with small support networks, emotion-focused coping styles, poorer health, low quality of life, and those caring for persons with higher numbers of behavioral problems need development and testing.

Canadian Alzheimer's disease caregiver survey: baby-boomer caregivers and burden of care

OBJECTIVE

Alzheimer's disease (AD) burdens not only the person, but also the person's caregiver(s). This burden has been linked to negative health effects for caregivers. To that end, a survey of Canadian caregivers of persons with AD/other dementias was conducted to investigate the social, physical, psychological and financial impact of AD and/or dementia-related conditions on caregivers' quality of life.

METHODS

A web-based survey, the Canadian Alzheimer's Disease Caregiver survey, was made available through the Canadian Alzheimer's Society website and 50plus.com, an internet portal for baby boomers (BB) (people aged 50 years or older), as well as through HarrisDecima Research's e-Vox panel. A total of 398 individuals completed the survey between 15 September and 5 November 2006.

RESULTS

Of the 398 total respondents, 221 were identified as baby boomers who provided care to an individual with AD/dementia. Respondents identified several areas of burden of care. These included negative effects on emotional health (such as increased depression, more stress and greater fatigue), financial costs and a need to change a working situation (e.g. by retiring early, reducing work hours or refusing a promotion).

CONCLUSION

Caregivers of persons with AD/related dementia face important social, physical, psychological and financial pressures. These negatively affect the quality of life of caregivers with a significant increased burden being placed on live-in caregivers versus caregivers who do not co-reside with their care recipients. Interventions that address these pressures will not only improve the health and well-being of caregivers, but likely also the care of persons with AD/dementia.

Effectiveness of a nurse-led case management home care model in Primary Health Care. A quasi-experimental, controlled, multi-centre study

Background

Demand for home care services has increased considerably, along with the growing complexity of cases and variability among resources and providers. Designing services that guarantee co-ordination and integration for providers and levels of care is of paramount importance. The aim of this study is to determine the effectiveness of a new case-management based, home care delivery model which has been implemented in Andalusia (Spain).

Methods

Quasi-experimental, controlled, non-randomised, multi-centre study on the population receiving home care services comparing the outcomes of the new model, which included nurse-led case management, versus the conventional one. Primary endpoints: functional status, satisfaction and use of healthcare resources. Secondary endpoints: recruitment and caregiver burden, mortality, institutionalisation, quality of life and family function. Analyses were performed at base-line, and at two, six and twelve months. A bivariate analysis was conducted with the Student's t-test, Mann-Whitney's U, and the chi squared test. Kaplan-Meier and log-rank tests were performed to compare survival and institutionalisation. A multivariate analysis was performed to pinpoint factors that impact on improvement of functional ability.

Results

Base-line differences in functional capacity – significantly lower in the intervention group (RR: 1.52 95%CI: 1.05–2.21; p = 0.0016) – disappeared at six months (RR: 1.31 95%CI: 0.87–1.98; p = 0.178). At six months, caregiver burden showed a slight reduction in the intervention group, whereas it increased notably in the control group (base-line Zarit Test: 57.06 95%CI: 54.77–59.34 vs. 60.50 95%CI: 53.63–67.37; p = 0.264), (Zarit Test at six months: 53.79 95%CI: 49.67–57.92 vs. 66.26 95%CI: 60.66–71.86 p = 0.002). Patients in the intervention group received more physiotherapy (7.92 CI95%: 5.22–10.62 vs. 3.24 95%CI: 1.37–5.310; p = 0.0001) and, on average, required fewer home care visits (9.40 95%CI: 7.89–10.92 vs.11.30 95%CI: 9.10–14.54). No differences were found in terms of frequency of visits to A&E or hospital re-admissions. Furthermore, patients in the control group perceived higher levels of satisfaction (16.88; 95%CI: 16.32–17.43; range: 0–21, vs. 14.65 95%CI: 13.61–15.68; p = 0,001).

Conclusion

A home care service model that includes nurse-led case management streamlines access to healthcare services and resources, while impacting positively on patients' functional ability and caregiver burden, with increased levels of satisfaction.
