The use of ecological momentary assessment for family caregivers of adults with chronic conditions: A systematic review

Background

Ecological momentary assessment (EMA) as a real-time data collection method can provide insight into the daily experiences of family caregivers.

Purpose

This systematic review aimed to synthesize studies involving EMA completed by family caregivers of adults with chronic conditions.

Methods

A systematic search was conducted within six databases for articles published from the inception of the database through September 2023. We extracted the characteristics of the included studies and data on EMA-specific methods to determine the quality of the included studies.

Results

A total of 12 studies involving EMA completed by family caregivers of adults with chronic conditions were identified, with almost all studies focused on caregivers of persons with Alzheimer's or dementia-related conditions. The average compliance rate across the included studies was 75%, below the recommended rate. In addition, most of the included studies did not collect the family caregivers' daily activities and care contexts in their responses (i.e., affect, stress, well-being, care demand, and fatigue) to the EMA prompts.

Discussion

This review showed that using EMA to collect information on family caregivers of adults with chronic health conditions appeared feasible and acceptable. However, the methodology or design of using EMA to collect caregiver information in this population is still preliminary. The limited number of existing studies that have used EMA to capture the daily experiences of family caregivers does not provide key information that could improve understanding of caregivers' emotional experiences and well-being in real-life situations. We identified gaps in the literature that warrant additional EMA studies for this population.

The experiences of caring for disabled older adults in long-term: A qualitative study from the perspective of spousal caregivers

OBJECTIVE

To explore the care experiences of spouses as long-term and primary caregivers for disabled older adults in China.

METHODS

A descriptive phenomenological method was used in this study, as well as purposive and convenient sampling. Semi-structured interviews were conducted with 15 spousal caregivers in Guangdong, China, from March to December 2021. Interview audio-recordings were transcribed verbatim and data were analyzed using Colaizzi's phenomenological analysis method.

RESULTS

We identified four themes from the data: spousal care motivation; sacrifices in caregiving; obstacles in caregiving; spousal caregivers' positive experiences.

CONCLUSIONS

Spouses took responsibility for providing care for their disabled partners regardless of their willingness. They had positive experiences while providing care, but negative experiences were dominant, especially for spouses of severely disabled older adults. Spouses are always perfect in caregiving roles, although they may also need medical assistance. To prevent a decline in spousal caregivers' quality of life and relieve their care burdens, health care providers should support them as soon as possible or offer formal care for disabled older adults. It is necessary to intervene considering disabled older adults and their spousal caregivers as a unit to empower their confidence in coping with life together.

The role of care-giver and mental health for older adults with disabilities: a mixed-method study

Because of the exacerbation of population ageing, more family members are involved in the informal care-giving for older adults with disabilities to cater to their long-term care needs. As informal care-givers are associated with the mental health of the care recipient, this study, based on the theoretical framework of the Actor–Partner Effect, utilises a mixed method composed of quantitative and qualitative strategies to identify the relationship among gender and type of both care-giver and care recipient, and mental health of the recipient and explain its internal mechanism. In the quantitative research, ordinary least squares (OLS) regression results based on the basis of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) data corroborate the existence of actor and partner effects within the care-giving dyad. The qualitative analysis further explains the socially constructed differences in gender role, trust relationship and perception towards filial piety of adult care-givers playing their role in the emergence of the Actor–Partner Effect. Finally, this study proposes a developed Actor–Partner Effect analysis framework, advocating to destigmatise disability and construct social support networks for the older adults with disabilities who receive informal care to promote their mental health based on the reflection of socially constructed gender difference.

Spousal concordance in frailty predicting mental and functional health decline: A four-year follow-up study of older couples in urban and rural China

AIMS AND OBJECTIVES

To examine the joint effects of self and spousal frailty status on functional and mental health in Chinese older adults and determine whether such effects vary by urban versus rural residency.

BACKGROUND

Frailty is a clinical syndrome among old adults and would lead to adverse outcomes. However, studies on the interactive patterns of frailty status between spouses and the joint effects of such patterns on health outcomes are scarce.

DESIGN

Data were from the China Health and Retirement Longitudinal Study (CHARLS). A total of 2,581 married seniors who participated both 2011 and 2015 waves of the CHARLS were categorised into four groups: robust self-robust spouse (RR), robust self-frail spouse (RF), frail self-robust spouse (FR) and frail self-frail spouse (FF).

METHODS

Frailty was measured using the physical frailty phenotype scale. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (CESD). Functional health was measured by difficulties in activities of daily living (ADL) and instrumental activities of daily living (IADL). The generalised estimating equation was used to estimate the effects of concordant frailty on mental and functional outcomes, stratified by rural/urban residency. This study followed the STROBE checklist.

RESULTS

The FF group reported higher levels of ADL/IADL difficulties and depressive symptoms at follow-up than the RR group; urban individuals in the RF group reported higher follow-up depression than the RR group; and rural individuals from the FR or RF groups reported more follow-up ADL/IADL difficulties than the RR group.

CONCLUSION

Frailty and subsequent health decline are interdependent in older couples, and the rural/urban context is important for understanding this interdependence in the older Chinese population.

RELEVANCE TO CLINICAL PRACTICE

Couples-based intervention strategies are needed to tackle situations in which one or both spouses are concurrently facing frailty.

Within-couple dissimilarities in functional impairment as determinants of spousal care arrangement among older married couples

Existing research on spousal care focuses on one spouse receiving care from the other, which fails to address the complexity that is created when both spouses experience some impairments. Our study included situations in which one or both spouses have functional impairments when examining the extent to which spouses from the same couple hold a (dis)similar level of functional impairment and whether such within-couple (dis)similarity has an impact on the spousal care arrangement. A subsample of 1170 older married couples was selected from the 2014 Health and Retirement Study. Descriptive statistics were used for describing the level of each spouse's functional impairment regarding the number of limitations in activities (activities of daily living [ADL]) or instrumental ADL (IADL). Logistic regressions were used to examine whether spousal dissimilarity in functional impairment (dissimilar, similarly low, similarly high) was associated with spousal care arrangement. Within couples with one functionally impaired spouse, the impaired spouse was more likely to receive spousal care when reporting a higher level of ADL/IADL impairment. Within couples with two functionally impaired spouses, the more impaired person was more likely to receive spousal care (without giving back) when spouses reported dissimilar level of IADL impairment; spouses were more likely to report mutual care when they had similarly high levels of IADL impairment. By documenting the role of spousal dissimilarities in functioning for determining spousal care arrangement, our study can inform couple-based interventions that capitalize on each spouse's capabilities and resources.

Associations Between Alzheimer's Disease and Related Dementias and Depressive Symptoms of Partner Caregivers

Family members-mainly spouses and partners-are the primary caregivers for individuals with Alzheimer's disease and related dementias (ADRDs), chronic progressive illnesses requiring increasing levels of care. We performed a retrospective observational analysis comparing depressive symptoms of 16,650 older individuals with partners without ADRDs, and those recently (within 2 years) or less recently diagnosed (≥2 years prior), controlling for lagged sociodemographic and health characteristics. The mean number of reported depressive symptoms was 1.2 (SD = 1.8). Compared with respondents with partners with no ADRD, having a partner with any ADRD was associated with a 0.35 increase (95% confidence interval [CI] = [0.30, 0.41]), or 30% increase, in depressive symptoms. A less recent partner diagnosis was associated with a 33% increase, while a recent diagnosis was associated with a 27% increase. Clinically meaningful and longitudinally worsening depressive symptoms amplify the need to prioritize partner health and family-centered care following an ADRD diagnosis.

Latina/o and non-latina/o brain injury and dementia patients’ and caregivers’ health: An actor/partner interdependence model

Background:

The interdependence between patient and caregivers’ health, which is when the patients’ and informal caregivers’ emotion, cognition and/or behavior affects that of the other person is well documented among dyads experiencing cancer and heart disease, but scant research has assessed interdependence among those with brain injuries or dementia and Latina/o populations. This study aimed to assess the interdependence of patient and caregiver depression, patient functional independence and caregiver burden among non-Latina/o and Latina/o and patients with brain injuries and dementia and their caregivers.

Methods:

Patients and caregiver dyads (n = 96) were recruited from a trauma hospital. Participants completed measures on patient and caregiver depression, patient functional independence and caregiver burden. Participants provided written informed consent. Patient inclusion criteria included: (1) diagnosis with a brain injury or dementia, (2) minimum age of 12, (3) community dwelling and (4) ability to verbally communicate and complete study measures. Caregivers were only included if they were informal, unpaid, family or a friend. Nonparametric Spearman’s Rho correlations were conducted to test the study hypotheses.

Discussion:

There was consistently a statistically significant positive relationship between caregiver depression and caregiver burden for all groups. For non-Latina/o patient and caregiver dementia dyads, there were associations between patient depression and caregiver depression. For non-Latina/o dementia dyads, functional ability was only associated with patient depression. For Latina/o patient and caregiver brain injury and dementia dyads, the only statistically significant relationship was between caregiver depression and caregiver burden. Health services should embrace family-focused mental health and respite interventions.

Caring for the informal cancer caregiver

PURPOSE OF REVIEW

Informal cancer caregivers play a vital role in the physical, functional, and emotional well being of cancer patients. However, the majority of informal caregivers are not prepared for their caregiving role. We reviewed and synthesized the recent literature (last 18 months) and focused on research in the following understudied areas: technology-driven interventions for informal caregivers; informal caregivers of older adults with cancer; interrelationship between informal caregiver and dyadic outcomes; and research priorities and guidelines to improve informal caregiver support.

RECENT FINDINGS

Studies focused on technology-driven informal caregiver interventions, with evidence of good feasibility and acceptability with benefits for burden and quality of life (QOL). Studies also focused on QOL for caregivers of older adults with cancer. Finally, research priorities and clinical guidelines were established through Delphi survey studies.

SUMMARY

Despite the substantial evidence on informal cancer caregiving, more research is needed to further characterize caregivers at high risk for burden, explicate interrelationships between caregiver/patient outcomes, and test innovative and scalable interventions. Studies are also needed to understand the specific needs of informal caregivers in cancer surgery, an understudied treatment population.
