The impact of care-recipient relationship type on health-related quality of life in community-dwelling older adults with dementia and their informal caregivers.

To assess whether there was an association between care-recipient relationship type and health-related quality of life (HRQL) of older persons living with dementia (PLWD) and their informal caregivers, and whether this association was affected by PLWD' dementia severity. This was a secondary data analysis study. PLWD (n = 1230) and caregivers (n = 1871) were identified from participants in the National Health and Aging Trends Study (NHATS) Round 5 and the National Study of Caregiving (NSOC) II, respectively. A series of bivariate and multivariable regression models examined the associations among relationship type and HRQL in PLWD and caregivers, adjusted for socio-demographic variables and dementia severity. PLWD and caregivers' HRQL outcomes varied by relationship type. PLWD cared for by an adult-child caregiver, or multiple caregivers experienced higher functional limitations than those cared for by a spousal caregiver (β = .79, CI [.39, 1.19]; β = .50, CI [.17, .82], respectively). "Other" caregivers, such as extended family members or friends, had lower odds of experiencing negative emotional burden and social strain than spousal caregivers (β = .79, CI [.39, 1.19]; β = .50, CI [.17, .82], respectively). Lower odds of experiencing negative emotional burden were also found with multiple caregivers. The effect of an adult-child caregiver on social strain was no longer significant when the dementia severity of PLWD was included in the analysis. The type of care-recipient relationship impacts the HRQL in both PLWD and their informal caregivers. Dementia severity of the PLWD appears to affect this association.

Impact of care-recipient relationship type on quality of life in caregivers of older adults with dementia over time.

Dementia caregiving is a dynamic and multidimensional process. To gain a comprehensive understanding of informal caregiving for people living with dementia (PLWD), it is pivotal to assess the quality of life (QoL) of informal caregivers. To evaluate whether the care-recipient relationship type predicts changes in the QoL of informal caregivers of PLWD over a two-year period. This was a secondary analysis of longitudinal data. The data were drawn from two waves of linked data from the National Health and Aging Trends Study (NHATS) and the National Study of Caregiving (NSOC) (2015: NHATS R5 & NSOC II; 2017: NHATS R7 & NSOC III). Caregivers were categorized into spousal, adult-child, "other" caregiver and "multiple" caregivers. QoL was assessed through negative emotional burden (NEB), positive emotional benefits and social strain (SS). Generalized estimating equation modelling was used to examine changes in caregivers' QoL outcomes across types of relationship over time. About, 882 caregivers were included who linked to 601 PLWD. After adjusting caregivers' socio-demographics, "other" caregivers had lower risk of NEB and SS than spousal caregivers (OR = 0.34, P = 0.003, 95%CI [0.17, 0.70]; OR = 0.37, P = 0.019, 95%CI 0.16, 0.85], respectively), and PLWD's dementia status would not change these significance (OR = 0.33, P = 0.003, 95%CI [0.16, 0.68]; OR = 0.31, P = 0.005, 95%CI [0.14, 0.71], respectively). The study demonstrates that spousal caregivers face a higher risk of NEB and SS over time, underscoring the pressing need to offer accessible and effective support for informal caregivers of PLWD, especially those caring for their spouses.

How both positive and burdensome caregiver experiences are associated with care recipient cognitive performance: Evidence from the National Health and Aging Trends Study and National Study of Caregiving.

Being an informal caregiver to a person with chronic disease, including persons living with dementia (PLWD), is a big role to take on and many caregivers experience both substantial burden and emotional reward related to caregiving. Care recipient factors (e.g., behavioral symptoms) are associated with caregiver experience. However, the relationship between caregiver and care recipient is bidirectional, so it is likely that caregiver factors impact the care recipient, though few studies have investigated this. In the 2017 round of the National Health and Aging Trends Study (NHATS) and National Study of Caregiving (NSOC), we studied 1,210 care dyads--170 PLWD dyads and 1,040 without dementia dyads. Care recipients completed immediate and delayed word list memory tasks, the Clock Drawing Test, and a self-rated memory rating, while caregivers were interviewed about their caregiving experiences using a 34-item questionnaire. Using principal component analysis, we created a caregiver experience score with three components-Practical Care Burden, Positive Care Experiences, and Emotional Care Burden. We then investigated the cross-sectional association between caregiver experience components and care recipient cognitive test performance using linear regression models adjusted for age, sex, education, race, and depressive and anxiety symptoms. Among PLWD dyads, a higher caregiver Positive Care Experiences score was associated with better care recipient performance on the delayed word recall (B = 0.20, 95% CI 0.05, 0.36) and Clock Draw (B = 0.12, 95% CI 0.01, 0.24) tests while higher Emotional Care Burden score was associated with worse self-rated memory score (B = -0.19, 95% CI -0.39, -0.003). Among participants without dementia, higher Practical Care Burden score was associated with poorer care recipient performance on the immediate (B = -0.07, 95% CI -0.12, -0.01) and delayed (B = -0.10, 95% CI -0.16, -0.05) word recall tests. These findings support the concept that caregiving is bidirectional within the dyad and that positive variables can positively impact both members of the dyad. This suggests that caregiving interventions should target the caregiver and recipient both individually and as a unit, with the goal of holistically improving outcomes for both.

Social support, positive caregiving experience, and caregiver burden in informal caregivers of older adults with dementia.

Dementia is currently one of the major causes of disability and dependency among older adults worldwide. Cognitive dysfunction, neuropsychiatric symptoms, somatic complaints, and functional impairment fundamentally affect not only a person living with dementia (PLwD), but also his/her informal caregiver(s), often resulting in a high caregiver burden. A number of variables, including the caregiver's sociodemographic characteristics, the clinical characteristics of PLwD, social support, and the caregiver's personal resources determine the caregiver's burden. The aim of this study was to investigate the associations of caregiver burden in informal caregivers of PLwD with perceived social support, positive caregiving experience, and applying therapeutic communication methods. The data were collected from September 2021 to February 2022 among 115 "PLwD-informal caregiver" dyads in the community settings in Slovakia. Measures included the Zarit Burden Interview (ZBI-12), the Oslo Social Support Scale (OSSS-3), the Positive Aspects of Caregiving Scale (PACS), and two questions on applying therapeutic communication methods-reminiscence and validation according to Naomi Feil. The Short IQCODE was used for assessing cognitive decline in PLwD. Pearson's and Spearman's correlations, t-tests, Chi-square, ANOVA, and linear multiple regression analyses were used to analyze the data (IBM SPSS 27). The mean age of informal caregivers was 54 ± 12.4 years (81.7% of women) and the mean caregiving duration was 4.8 ± 4.8 years. The mean age of PLwD was 80.5 ± 8.3 years (73.0% of women) and their Short IQCODE mean score was 4.1 ± 1.0. Lower caregiving burden was significantly associated with higher perceived social support (β = 0.33, p < 0.01), with higher positive caregiving experience (β = 0.33, p < 0.01), and higher caregiving intensity (β = 0.24, p < 0.05) among informal caregivers of PLwD. The associations between caregiver burden and applying two therapeutic communication methods were not significant. Implementing psycho-social and educational public health interventions focused on strengthening social support and maintaining positive perceptions of caregiving can help reduce the increased risk of caregiver burden in informal caregivers of older adults with dementia.
