The relationship among caregiving characteristics, caregiver strain, and health-related quality of life: evidence from the Survey of the Health of Wisconsin

Factors Associated With Working Caregivers' Well-Being: Comparisons Between Black and White Working Caregivers in the United States

This study investigated stressors and strains, resources, and well-being among Black working caregivers (BWC) and White working caregivers (WWC) who participated in the Midlife in the United States study (Black: n  =  49, White: n  =  250). Comparisons were made between BWC and WWC for primary caregiving stressors, secondary strains, resources, and well-being, and hierarchical regression models tested associations among these factors. BWC reported less negative work-to-family spillover, more perceived control and religious/spiritual coping, and higher positive affect than WWC, complementing existing evidence of greater resilience among BWC. Secondary strains stemming from the workplace had stronger associations with well-being than primary caregiving stressors, confirming that the workplace deserves greater attention in stress research and interventions for working caregivers. Finally, perceived control, optimism, and family support were important resources for well-being for both BWC and WWC, substantiating their valuable role in interventions for working caregivers.

Impact of Residential Segregation on Healthcare Utilization and Perceived Quality of Care Among Informal Caregivers in the United States

This study aimed to investigate the impact of racial residential segregation on healthcare utilization and perceived quality of care among informal caregivers in the US. It further assessed potential variations in the estimated impact across caregivers' race and socioeconomic status. We used data from the Health Information National Trends Survey Data Linkage Project (fielded in 2020) for a sample of 583 self-identified informal caregivers in the US. Fitting a series of regression models with the maximum likelihood estimation, we computed the beta coefficients (β) of interest and their associated Wald 95% confidence limits (CI). Caregivers who resided in areas with higher segregation, compared to those living in lower segregated areas, were less likely to visit a healthcare professional [β =  - 2.08; Wald 95%CI - 2.093, - 2.067] (moderate); [β =  - 2.53; Wald 95%CI - 2.549, - 2.523] (high)]. Further, caregivers residing in moderate [β =  - 0.766; Wald 95%CI - 0.770, - 0.761] and high [β =  - 0.936; Wald 95%CI - 0.941, - 0.932] segregation regions were less likely to perceive a better quality of care compared to those located in low segregation areas. Moreover, as segregation level increased, Black caregivers were less likely to see a health professional, less frequently used healthcare services, and had poorer perceived healthcare quality when compared to Whites. Our findings indicate that higher residential segregation is associated with lower healthcare utilization, such as visiting a healthcare professional, and poorer perceived healthcare quality among informal caregivers. Given the essential role of informal caregivers in the current healthcare system, it is vital to investigate and address challenges associated with access to and quality of essential healthcare services to improve caregivers' health and well-being, specifically for caregivers of minority backgrounds.

The association between loneliness with health service use and quality of life among informal carers in Australia

OBJECTIVE

The demanding nature of caregiving and limited social support can lead to informal carers experiencing loneliness, which can impact their well-being and overall health service use (HSU). The study aims to examine the association between loneliness with HSU and Health state utility values among informal carers in Australia.

METHODS

Data were derived from three waves (2009, 2013, and 2017) of the nationally representative longitudinal Household Income and Labour Dynamics of Australia (HILDA) survey, focusing on adult informal carers. Outcome measures included visits to the General Practitioner, the number of hospital admissions, and the SF-6D score. Generalized Estimating Equations (GEE) analysis was conducted to explore the associations between loneliness and HSU, as well as loneliness and utility values (based on SF-6D) while adjusting for age, sex, education, marital status, income, and physical/mental health conditions.

RESULTS

After controlling for covariates, lonely carers reported lower utility values (IRR = 0.91, 95%CI [0.89, 0.93], p < 0.001) compared to non-lonely carers. Lonely carers reported a higher number of GP visits (IRR = 1.18, 95% CI [1.04, 1.36], p < 0.05) as well as a higher likelihood of visiting specialists (AOR = 1.31, p = 0.046) and hospital doctors (AOR = 1.42, p = 0.013) compared to the non-lonely carers.

CONCLUSIONS

The findings of this study highlight the relationship between loneliness on both healthcare utilization and carers' overall well-being. Addressing loneliness through targeted interventions and social support systems can help improve health outcomes and potentially reduce the overall healthcare costs among informal carers in Australia.

Quality of Life and Incidence of Clinical Signs and Symptoms among Caregivers of Persons with Mental Disorders: A Cross-Sectional Study

BACKGROUND

Caring for individuals with mental disorders poses significant challenges for caregivers, often leading to compromised quality of life and mental health issues such as stress, anxiety, and depression. This study aims to assess the extent of these challenges among caregivers in Greece, identifying which demographic factors influence their well-being.

METHOD

A total of 157 caregivers were surveyed using the SF-12 Health Survey for quality-of-life assessment and the DASS-21 questionnaire for evaluating stress, anxiety, and depression symptoms. t-tests, Kruskal-Wallis tests, Pearson's correlation coefficients, and regression analyses were applied to understand the associations between demographics, quality of life, and mental health outcomes.

RESULTS

The study found that caregivers, especially women and younger individuals, faced high levels of mental health challenges. Marital status, educational level, and employment status also significantly influenced caregivers' well-being. Depression was the most significant factor negatively correlating with the mental component of quality of life. The magnitude of the burden experienced by caregivers highlighted the urgency for targeted social and financial support, as well as strategic treatment programs that consider caregiver well-being.

CONCLUSIONS

Caregivers of individuals with mental disorders endure significant stress, anxiety, and depression, influencing their quality of life. Demographic factors such as age, gender, marital status, education, and employment status have notable impacts. Findings emphasize the need for society-wide recognition of caregivers' roles and the creation of comprehensive support and intervention programs to alleviate their burden, particularly in the context of the COVID-19 pandemic.

Spanish adaptation of the Gender-Related Variables for Health Research (GVHR): Factorial Structure and Relationship with Health Variables

The aim of the present study was to conduct a preliminary study of the Stanford Gender-Related Variables for Health Research (GVHR) adapted to the Spanish population, testing its factor structure, sex factorial invariance and relationship with health variables. Participants were 438 adults between 19-73 years old (M = 31.90, SD = 12.12) who completed the GVHR and measures of health-related quality of life, psychological health, and health-risk behaviors. The confirmatory factorial analysis of the GVHR indicated an acceptable fit to the 7-factor structure as proposed for the North American population. Emotional intelligence and independence factors had low internal consistency, therefore, a five-factor model was tenable in the Spanish population. Sex scalar invariance was tenable, indicating that the factors latent means can be meaningfully compared across sex. Univariate logistic regressions indicated that women reported worse mental and physical health and more health limitations, but this effect dissipated when gender variables were considered. Caregiver and work strain stood out as the variables related to gender that predicted worse health-related quality of life, psychological health, and health-risk behaviors. In conclusion, factorial structure of the GVHR may differ from one culture to another. Additionally, the variables related to gender in the GVHR give a better account of the differences in health compared to biological sex.

Perceptions of people living with dementia regarding patient-centred aspects of their care and caregiver support

OBJECTIVE

This study examined the perceptions of a sample of Australian people living with dementia regarding the person-centred care and support they received from health professionals and family.

METHODS

Community-dwelling people living with dementia were invited to complete a cross-sectional survey.

RESULTS

Seventy-one people participated in the study. More than 90% agreed that health professionals explain who they are, why they are seeing them and listen to what they have to say; 63% agreed that health professionals ask how they would like to be involved in decisions about treatment; 78% agreed health professionals mainly speak to them rather than anyone accompanying them; 76% reported their family 'support you to do tasks by yourself', and 36% indicated that family caregivers 'get frustrated with you'.

CONCLUSIONS

Results suggest that people living with dementia have a positive perception of the care and support they receive. Improvements may be needed in how health professionals speak directly to the person living with dementia when exploring how they would like to be involved in treatment decisions. Family caregivers may benefit from education and support on how they can manage frustrations and assist the person they support to maintain their independence.

Caregiving and Confidence to Avoid Hospitalization for Children with Medical Complexity

OBJECTIVE

To test associations between parent-reported confidence to avoid hospitalization and caregiving strain, activation, and health-related quality of life (HRQOL).

STUDY DESIGN

In this prospective cohort study, enrolled parents of children with medical complexity (n = 75) from 3 complex care programs received text messages (at random times every 2 weeks for 3 months) asking them to rate their confidence to avoid hospitalization in the next month. Low confidence, as measured on a 10-point Likert scale (1 = not confident; 10 = fully confident), was defined as a mean rating <5. Caregiving measures included the Caregiver Strain Questionnaire, Family Caregiver Activation in Transition (FCAT), and caregiver HRQOL (Medical Outcomes Study Short Form 12 [SF12]). Relationships between caregiving and confidence were assessed with a hierarchical logistic regression and classification and regression trees (CART) model.

RESULTS

The parents were mostly mothers (77%) and were linguistically diverse (20% spoke Spanish as their primary language), and 18% had low confidence on average. Demographic and clinical variables had weaker associations with confidence. In regression models, low confidence was associated with higher caregiver strain (aOR, 3.52; 95% CI, 1.45-8.54). Better mental HRQOL was associated with lower likelihood of low confidence (aOR, 0.89; 95% CI, 0.80-0.97). In the CART model, higher strain similarly identified parents with lower confidence. In all models, low confidence was not associated with caregiver activation (FCAT) or physical HRQOL (SF12) scores.

CONCLUSIONS

Parents of children with medical complexity with high strain and low mental HRQOL had low confidence in the range in which intervention to avoid hospitalization would be warranted. Future work could determine how adaptive interventions to improve confidence and prevent hospitalizations should account for strain and low mental HRQOL.

Health-Related Quality of Life and Perceived Burden of Informal Caregivers of Patients with Rare Diseases in Selected European Countries

Most of rare disease (RD) patients are assisted in their homes by their family as informal caregivers, causing a substantial burden among family members devoted to care. The role of informal caregivers has been associated with increased levels of stress, poor physical/mental health and impaired HRQOL. The present study assessed the impact on HRQOL and perceived burden of long-term informal caregiving, as well as the inter-relationships of individuals affected by different RD in six European countries, taking advantage of the data provided by the BURQOL-RD project (France, Germany, Italy, Spain, Sweden and UK). Correlation analysis was used to explore the relation between caregiver HRQOL and caregiver burden (Zarit Burden Interview). Multinomial logistic regression models were used to explore the role of explanatory variables on each domain of caregivers HRQOL measured by EQ-5D. Caregivers' HRQOL is inversely correlated with burden of caring. Mobility dimension of EQ-5D was significantly associated with patients age, time devoted to care by secondary caregivers, patient gender and patient utility index. Patients' age, burden scores and patient utility index significantly predict the capacity of caregivers to perform activities of daily living. Employed caregivers are less likely of reporting 'slight problems' in pain/discomfort dimensions than unemployed caregivers. The EQ-5D instrument is sensitive to measure differences in HRQOL between caregivers with different levels of burden of care.

The Survey of the Health of Wisconsin (SHOW) Program: An Infrastructure for Advancing Population Health

Introduction

The Survey of the Health of Wisconsin (SHOW) was established in 2008 by the University of Wisconsin (UW) School of Medicine and Public Health (SMPH) with the goals of (1) providing a timely and accurate picture of the health of the state residents; and (2) serving as an agile resource infrastructure for ancillary studies. Today, the SHOW program continues to serve as a unique and vital population health research infrastructure for advancing public health.

Methods

SHOW currently includes 5,846 adult and 980 minor participants recruited between 2008 and 2019 in four primary waves. WAVE I (2008–2013) includes annual statewide representative samples of 3,380 adults ages 21 to 74 years. WAVE II (2014–2016) is a triannual statewide sample of 1,957 adults (age ≥18 years) and 645 children (age 0–17). WAVE III (2017) consists of follow-up of 725 adults from the WAVE I and baseline surveys of 222 children in selected households. WAVEs II and III include stool samples collected as part of an ancillary study in a subset of 784 individuals. WAVE IV consists of 517 adults and 113 children recruited from traditionally under-represented populations in biomedical research including African Americans and Hispanics in Milwaukee, Wisconsin.

Evaluating the provision of Further Enabling Care at Home (FECH+) for informal caregivers of older adults discharged home from hospital: protocol for a multicentre randomised controlled trial

INTRODUCTION

There are personal and societal benefits from caregiving; however, caregiving can jeopardise caregivers' health. The Further Enabling Care at Home (FECH+) programme provides structured nurse support, through telephone outreach, to informal caregivers of older adults following discharge from acute hospital care to home. The trial aims to evaluate the efficacy of the FECH+ programme on caregivers' health-related quality of life (HRQOL) after care recipients' hospital discharge.

METHODS AND ANALYSIS

A multisite, parallel-group, randomised controlled trial with blinded baseline and outcome assessment and intention-to-treat analysis, adhering to Consolidated Standards of Reporting Trials guidelines will be conducted. Participants (N=925 dyads) comprising informal home caregiver (18 years or older) and care recipient (70 years or older) will be recruited when the care recipient is discharged from hospital. Caregivers of patients discharged from wards in three hospitals in Australia (one in Western Australia and two in Queensland) are eligible for inclusion. Participants will be randomly assigned to one of the two groups. The intervention group receive the FECH+ programme, which provides structured support and problem-solving for the caregiver after the care recipient's discharge, in addition to usual care. The control group receives usual care. The programme is delivered by a registered nurse and comprises six 30-45 min telephone support sessions over 6 months. The primary outcome is caregivers' HRQOL measured using the Assessment of Quality of Life-eight dimensions. Secondary outcomes include caregiver preparedness, strain and distress and use of healthcare services. Changes in HRQOL between groups will be compared using a mixed regression model that accounts for the correlation between repeated measurements.

ETHICS AND DISSEMINATION

Participants will provide written informed consent. Ethics approvals have been obtained from Sir Charles Gairdner and Osborne Park Health Care Group, Curtin University, Griffith University, Gold Coast Health Service and government health data linkage services. Findings will be disseminated through presentations, peer-reviewed journals and conferences.

ARTICLE SUMMARY

Strengths and limitations: The Survey of the Health of Wisconsin (SHOW) is an infrastructure to advance population health sciences including biological sample collection and broader data on individual and neighborhood social and environmental determinants of health.The extensive data from diverse urban and rural populations offers a unique study sample to compare how socio-economic gradients shape health outcomes in different contexts.The objective health data supports novel interdisciplinary research initiatives and is especially suited for research in causes and consequences of environmental exposures (physical, chemical, social) across the life course on cardiometabolic health, immunity, and aging related conditions.The extensive biorepository supports novel omics research into common biological mechanisms underlying numerous complex chronic conditions including inflammation, oxidative stress, metabolomics, and epigenetic modulation.Ancillary studies, such as the Wisconsin Microbiome Study, have expanded the utility of the study to examine human susceptibility to environmental exposures and opportunities for investigations of the role of microbiome in health and disease.Long-standing partnerships and recent participation among traditionally under-represented populations in biomedical research offer numerous opportunities to support community-driven health equity work.No biological samples were collected among children.The statewide sampling frame may limit generalizability to other regions in the United States.

Caregiving Intensity and Mortality in Older Women, Accounting for Time-Varying and Lagged Caregiver Status: The Caregiver-Study of Osteoporotic Fractures Study

BACKGROUND AND OBJECTIVES

Caregiving is associated with reduced mortality in recent studies. Investigations of caregiving intensity may reveal an underlying mechanism. However, studies of caregiving intensity and mortality have mixed results, perhaps due to imprecise measurement of caregiving intensity, not accounting for healthier persons likely having greater caregiving involvement, or temporal changes in intensity. We examined the relationship between caregiving intensity (based on tasks performed) and mortality, treating intensity and health status as time-varying, and lagging exposure.

RESEARCH DESIGN AND METHODS

Caregiving tasks among 1,069 women in the Caregiver-Study of Osteoporotic Fractures study (35% caregivers) were assessed at 5 interviews conducted between 1999 and 2009. Caregivers were categorized as high intensity if they assisted a person with dressing, transferring, bathing, or toileting; or as low intensity if they assisted with other instrumental or basic activities of daily living (I/ADLs). Alternatively, high intensity was defined as assisting with more than the median number of I/ADL tasks (median-based measure). Mortality was assessed through 2011. Cox proportional hazards models estimated adjusted hazard ratios (aHR) and 95% confidence intervals based on concurrent intensity, and lagging exposure 2 years.

RESULTS

High-intensity caregivers had significantly lower mortality using the median-based measure after lagging exposure (aHR = 0.55, 0.34-0.89). Similar, but not statistically significant associations were observed in non-lagged analyses (aHR = 0.54, 0.29-1.04) and task-specific intensity (aHRs were 0.61 and 0.51). Low-intensity caregivers had similar mortality rates to noncaregivers in all analyses.

DISCUSSION AND IMPLICATIONS

Among older women, high-intensity caregivers had lower mortality rates than noncaregivers. Whether this association extends to other populations merits investigation.

Intensive Mothers, Cautionary Tale Fathers: Adult Children's Perceptions of Parental Influence on Health

Parents strongly influence children's health, yet how parents continue to shape the health of midlife adult children remains unknown. Moreover, while most adults are married by midlife, research has failed to identify the effects of parent-in-law relationships on midlife adult wellbeing. Using interviews with 90 individuals in 45 marriages, we investigate how midlife adults perceive the influence of parents and parents-in-law on adult child health. Findings reveal that particularly mothers and mothers-in-law positively influence child's health via support during, or in anticipation of, illness and injury. The health experiences of parents and in-laws, particularly fathers/in-law, become cautionary tales preparing adult children for future health issues. Yet, parents/in-law also have negative influence on adult children during midlife due to parents' compounding health needs. We use family systems theory to show how parents/in-laws are intertwined in ways that influence health during children's midlife that has ramifications into later life.

The Modified Caregiver Strain Index: Portuguese version

The Modified Caregiver Strain Index is a widely used tool to screen for caregiver strain in family caregivers. This study presents the Portuguese version of the Modified Caregiver Strain Index and explores its psychometric properties in a sample of 347 informal caregivers of older dependent individuals. Factor analysis revealed a two-factor structure and indicated satisfactory internal consistency. Criterion-related validity was supported by positive significant correlations with the emotional health of the caregiver (psychological distress). The findings show evidence of reliability and validity of the Portuguese version of the Modified Caregiver Strain Index encouraging its use in clinical and research fields.

Strain Among Caregivers of Older Adults Diagnosed With Breast Cancer

OBJECTIVES

To illustrate the predictors of strain among caregivers of older adults diagnosed with breast cancer.

SAMPLE & SETTING

This study involved 39 women diagnosed with breast cancer who were aged 69 years or older, receiving any type of treatment, and seeking an initial assessment in a geriatric oncology program at a large cancer center in the midwestern United States and their caregivers.

METHODS & VARIABLES

This cross-sectional study evaluated relationships among the variables of caregiver strain, age, employment status, patient characteristics, and patient scores on the comprehensive geriatric assessment. Bivariate statistics and logistic regression models were used.

RESULTS

Increasing age of the caregiver was associated with less caregiver strain. Caregivers employed part-time experienced greater strain than those employed full-time.

IMPLICATIONS FOR NURSING

Nurses must assess for strain in caregivers of individuals diagnosed with cancer, particularly if they are younger and employed part-time. Caregivers of depressed patients should be assessed for strain and offered support.

The Relationship of Caregiving to Work Conflict and Supervisor Disclosure With Emotional, Physical, and Financial Strain in Employed Family Caregivers

Objective: To determine whether employed family caregiver reports of caregiving to work conflict (CWC) are associated with emotional, physical, and financial strain, and whether organizational factors, including supervisor disclosure and caregiver-friendly workplace policies, attenuate these effects. Method: We examined 369 full-time employed caregivers of adults aged 50 years and above from the 2015 AARP and National Alliance for Caregiving population-based study, Caregiving in the United States, using ordinary least squares hierarchical regression and moderation analyses. Results: Regression analyses showed that caregiver reports of more CWC, in addition to disclosure of caregiving, were associated with greater emotional, physical, and financial strain after controlling for demographics and caregiving stressors, and workplace policies did not attenuate strain. Neither disclosure nor policies moderated the impact of CWC on caregiver strain. Discussion: Results suggest the importance of workplace strain in the caregiving stress process and suggest that disclosing caregiving responsibilities to supervisors should be closely examined.

Population Characteristics and Needs of Informal Caregivers Associated With the Risk of Perceiving a High Burden: A Cross-Sectional Study

This study explored the population characteristics and needs of informal caregivers reporting a low or high burden. A cross-sectional study was conducted in the Netherlands to explore the associations between the characteristics and needs of informal caregivers and the burden they perceive and to assess the variance in perceived burdens that is explained by these variables. Three thousand sixty-seven adult informal caregivers and 1936 senior informal caregivers participated, almost 15% of whom perceived a high burden. Particularly caregivers in the 40 to 54 age group perceived a high burden, while caregivers with an intermediate educational level reported a low burden. Higher burden was also reported by caregivers who spent more time on the care provision tasks, had a high level of depressive symptoms, or reported loneliness. The explored variables seem to be important to explain caregiver burden. Longitudinal research is warranted to establish the causal directions of these associations.

The Relationship Between Mutuality and Health-Related Quality of Life in Adult Child Caregivers in China

The strain inherent in caregiving relationships between adult children and aging parents is a prominent issue in contemporary China due to a combination of demographic and socioeconomic changes. The purpose of this study was to explore how mutuality, a positive quality of caregiving relationships, contributes to the physical health and mental health (health-related quality of life [HRQoL]) of adult child caregivers [ACCs] of parent stroke survivors. A cross-sectional correlational study was conducted on a nonproportional quota sample of 126 ACCs, using questionnaires of demographics, the 15-item Mutuality Scale, and the Second Version of the Standard 12-Item Health Survey (SF-12v2). Higher mutuality was found to be correlated with better caregiver physical health and mental health. However, after adjusting for the covariates, mutuality significantly explained 4.6% of the variance of caregiver physical health (β = .22, ΔR² = .046, p < .01) but it did not significantly explain the variance of caregiver mental health. Although multiple factors correlate with Chinese family caregivers' HRQoL, this was the first study exploring the impact of caregiver-care receiver dyadic relationships on caregiver HRQoL in mainland China by using a mutuality scale with SF-12v2. Despite the fact that the Chinese tradition of filial piety can facilitate mutuality, socioeconomic changes and legislation that require adult children to care for aging parents appear to create high stress among family caregivers. Higher levels of mutuality contribute to better physical health in Chinese family caregivers. Therefore, culturally appropriate family nursing strategies and social policies in China could enhance caregiver mutuality and potentially promote their HRQoL, in particular physical health.

Impact of caregiver activities and social supports on multidimensional caregiver burden: analyses from nationally-representative surveys of cancer patients and their caregivers

PURPOSE

Informal caregivers of individuals with cancer may experience substantial burdens. To develop interventions to support these caregivers, it is crucial to quantify and understand the domains of burdens potentially experienced by caregivers and factors contributing to each domain.

METHODS

Using data from two national surveys, the National Survey of Caregiving (NSOC) linked to the National Health and Aging Trends Survey (NHATS), we identified all participants in the NHATS diagnosed with cancer who had a caregiver participating in the NSOC. Guided by a theoretical model, twenty-two items in the NSOC related to caregiver health, mood and outlook were included in factor analysis to develop scales capturing domains of burden. Multivariable regression analyses examined whether activities performed by caregivers and supports for caregivers were associated with these burden scales.

RESULTS

Analysis of responses from 373 caregivers of cancer patients identified three scales: emotional burden; psychological burden; and relationship with the patient. Providing assistance managing medical care was associated with increased emotional and psychological burden, while assistance with non-medical issues increased psychological burden and worsened relationships with patients. Caregiver provision of direct patient care activities was also associated with increased burden but improved relationships with patients. Use of caregiver supports showed mixed associations with burden.

CONCLUSIONS

Using a nationally-representative sample of cancer patients and their caregivers and brief publicly-available survey questions, we present three scales addressing different aspects of caregiver burden that are responsive to caregiver activities and social supports. This may assist in developing and evaluating intervention to decrease caregiver burden.
