Immediate and Lagged Effects of Daily Stress and Affect on Caregivers' Daily Pain Experience

Physical pain among family caregivers to older adults: A scoping review of the literature

BACKGROUND AND OBJECTIVES

Scholarship on the health of family caregivers to older adults continues to expand. Although existing research suggests that many family caregivers experience pain, which impacts their ability to perform caregiving tasks and is associated with care recipients' unmet needs, the scope of research on family caregivers' pain remains poorly characterized. We conducted a scoping review of research on pain among family caregivers to older adults to characterize existing evidence and identify knowledge gaps.

METHODS

We searched multiple databases spanning from January 2012 to July 2023, identified eligible studies using predefined inclusion/exclusion criteria, and extracted key data (e.g., study design/methodology, pain measurement, caregiver pain type, and major findings).

RESULTS

We identified 46 eligible studies conducted in the United States (n = 19) and internationally (n = 27). Studies often focused on caregivers for older adults with specific health conditions, such as cancer (n = 11), dementia (n = 8), or stroke (n = 3). The most commonly employed pain measure was a single-item dichotomous question about pain (n = 16), followed by a visual numeric or visual analog scale (n = 11). Nine studies (five randomized controlled trials) reported on five caregiver pain management interventions, including yoga/exercise programs and caregiver education programs.

DISCUSSION

Existing research on family caregivers' pain offers an important foundation. However, more robust research designs are necessary. We identify possibilities for future studies in addition to opportunities for systematic investigations to support the family caregivers being relied upon to care for the increasing number of older adults.

Prevalence Estimates of Arthritis and Activity-Limiting Pain Among Family Caregivers to Older Adults

BACKGROUND AND OBJECTIVES

Little is known about the prevalence of physical pain among family caregivers to older adults. We used national survey data to assess the relative prevalence of caregivers' arthritis and activity-limiting bothersome pain by caregiver and care-recipient characteristics to identify which caregivers may be at a higher risk for physical pain.

RESEARCH DESIGN AND METHODS

We analyzed data collected from 1,930 caregivers who participated in the National Study on Caregiving (2017). We utilized modified Poisson models to estimate adjusted associations of caregiver and care-recipient characteristics with the relative prevalence of arthritis and bothersome pain.

RESULTS

Forty percent of caregivers had a lifetime diagnosis of arthritis. Seventy-five percent of caregivers with arthritis reported bothersome pain, nearly 30% of whom endorsed bothersome pain that limited their activities on most or every day of the previous month (i.e., activity-limiting bothersome pain). Regardless of whether they had arthritis, 51% of the sample reported bothersome pain in the previous month, 24% of whom indicated activity-limiting bothersome pain. Caregivers who were older or more highly educated had a higher prevalence of arthritis. Black caregivers had a lower prevalence of arthritis and activity-limiting bothersome pain compared to White caregivers. Caregivers with physical difficulty providing care had a higher prevalence of arthritis and activity-limiting bothersome pain than caregivers without physical difficulty providing care.

DISCUSSION AND IMPLICATIONS

Arthritis and activity-limiting bothersome pain are highly prevalent among caregivers. Given increased prevalence of pain among certain caregivers, it may be efficient to target these groups for pain management interventions.

A scoping review of intensive longitudinal methods in informal caregivers of people with dementia

BACKGROUND

The daily life of informal caregivers assisting individuals with dementia widely varies throughout the day and week. As an answer, an increasing number of researchers have used intensive longitudinal methods (ILMs) such as diary studies, experience sampling methods, or ecological momentary assessment.

OBJECTIVES AND METHODS

The present scoping review aims at synthesizing the use of ILMs in informal dementia caregivers to clarify what is currently done and how, as well as what remains unaddressed.

RESULTS

The screening process identified 48 studies from 22 different datasets. Synthesis of these studies showed the diversity of devices and uses of ILMs in informal care, including the exploration of associations between variables or accompanying an intervention. ILMs showed the important variability of caregiving phenomena, as well as the important association of momentary stress and well-being. Gaps were nevertheless identified, such as transparency in the construction of the tool or the absence of focus on emotions and dyads.

CONCLUSIONS

For now, this field of research remains in its infancy and does not seem to have reached its full potential as it has in other fields. Nevertheless, it appears that ILMs are promising tools for informal dementia caregivers as they contribute to understanding the complexity of their daily life, with changing resources and challenges. Future directions include focusing more on (emotion) regulation, temporal lags, and the use of ILMs in interventional designs.

TRIAL REGISTRATION

The present review was registered on OSF (osf.io/b2qr4).

Perceived role overload and physical symptom experience among caregivers of older adults: The moderating effect of social support

We investigated the association between perceived role overload and physical symptom experience, and the potential moderating effect of social support among caregivers of older adults. We analyzed data of 1,471 caregivers obtained from the 2017 National Study of Caregiving. In the survey, participants were assessed for physical symptoms (pain, limited leg strength, and low energy), symptom-related activity limitations, perceived role overload, and informal/formal support sources. We performed multiple logistic regression analyses with interaction terms. Caregivers who perceived higher role overload were more likely to experience the physical symptoms and frequent limited activities due to the symptoms. The associations of perceived role overload with pain and low energy, respectively, were attenuated among caregivers with high informal support. The moderating effect of formal support appeared to be the opposite in relation to pain. Caregivers who perceived high burden may benefit from their informal support to prevent detrimental effects of caregiving on physical health.

Women's Self-Relevant Goal Pursuit in the Presence of Physical Pain: An Intraindividual Variability Approach

OBJECTIVES

Pursuing personal goals that are relevant to one's sense of self is important for adjusting to age-related changes. Experiences of physical pain, however, are thought to threaten both people's sense of self and their pursuit of personal goals. Although a majority of older women experience physical pain, little is known about their day-to-day regulation of their self-relevant goals in the presence of physical pain. The objectives of this study were to explore associations between physical pain and health goal pursuit on a daily basis for women who identified health as a part of their possible selves.

METHODS

We took an intraindividual variability approach to analyze whether there were within- and between-person differences in associations between daily pain and daily health goal progress among 62 women who provided data over the course of 100 days, yielding 4,150 occasions of data.

RESULTS

At the between-person level, women with higher pain on average had lower health goal pursuit on average. At the within-person level, days of higher-than-average pain were associated with lower same-day health goal progress.

DISCUSSION

Our results suggest that pain interrupts regulation of a self-relevant goal at a within-person-not just between-person-daily level. Future work should consider how these daily, within-person, disruptions affect broader identity processes and overall well-being.

Quality of life in caregivers of patients receiving chimeric antigen receptor T-cell therapy

OBJECTIVE

Informal family caregivers provide critical support for patients receiving chimeric antigen receptor (CAR) T-cell therapy. However, caregivers' experiences are largely unstudied. This study examined quality of life (QOL; physical functioning, pain, fatigue, anxiety, and depression), caregiving burden, and treatment-related distress in caregivers in the first 6 months after CAR T-cell therapy, when caregivers were expected to be most involved in providing care. Relationships between patients' clinical course and caregiver outcomes were also explored.

METHODS

Caregivers completed measures examining QOL and burden before patients' CAR T-cell therapy and at days 90 and 180. Treatment-related distress was assessed at days 90 and 180. Patients' clinical variables were extracted from medical charts. Change in outcomes was assessed using means and 99% confidence intervals. Association of change in outcomes with patient clinical variables was assessed with backward elimination analysis.

RESULTS

A total of 99 caregivers (mean age 59, 73% female) provided data. Regarding QOL, pain was significantly higher than population norms at baseline but improved by day 180 (p < .01). Conversely, anxiety worsened over time (p < .01). Caregiver burden and treatment-related distress did not change over time. Worsening caregiver depression by day 180 was associated with lower patient baseline performance status (p < .01). Worse caregiver treatment-related distress at day 180 was associated with lower performance status, intensive care unit admission, and lack of disease response at day 90 (ps < 0.01).

CONCLUSIONS

Some CAR T-cell therapy caregivers experience pain, anxiety, and burden, which may be associated patients' health status. Further research is warranted regarding the experience of CAR T-cell therapy caregivers.

Agitation in people with dementia: A concept analysis

AIM

This article aims to clarify the concept of agitation in people with dementia (PWD) by identifying its attributes, antecedents, and consequences to propose an operational definition of the concept.

BACKGROUND

Agitation is a recurrent behavior problem for many people with and without dementia, which results in psychosocial distress. The current literature lacks the conceptual clarity of agitation, which limits its effective nursing management.

DATA SOURCES

Several databases search was utilized that comprise computer searches of PsycINFO, MEDLINE (PubMed), the Cumulative Index of Nursing and Allied Health of data between the years 1970 and 2013.

DESIGN

Concept analysis.

REVIEW METHODS

Rodgers' Evolutionary Method of concept analysis (2000) was employed as a guide for analyzing the agitation concept.

RESULTS

Four main attributes were used to describe and propose a definition of agitation in PWD: disruptive behaviors, repetitiveness, inappropriateness, and aggression.

CONCLUSION

This analysis provides an operational definition that will improve knowledge of investigating relevant issues to agitation, which can be used by nurses and family caregivers when managing and preventing agitation in PWD.

Interpersonal Tensions and Pain Among Older Adults: The Mediating Role of Negative Mood

OBJECTIVES

To examine whether (a) negative social encounters and physical pain are linked throughout the day, (b) negative mood mediates these associations, and (c) these associations vary by closeness with social partners.

METHOD

Adults aged 65+ (n = 313) completed ecological momentary assessments and reported their negative social encounters, physical pain, and mood every 3 hr throughout the day for 5-6 days.

RESULTS

Multilevel models revealed that negative social encounters were associated with greater pain at each 3-hr interval and that this association was mediated by negative mood during the same interval. Negative encounters with less close partners were associated with pain, but negative encounters with close partners were not.

DISCUSSION

Regulating older adults' negative emotions may be crucial to improving their daily pain. Further, interventions focusing on negative encounters with less close partners in daily life may help mitigate older adults' experiences of pain throughout the day.

Intra- and interindividual differences in the within-person coupling between daily pain and affect of older adults

The bidirectional interplay between chronic pain and negative affect is well-established in patient samples. However, less is known about the day-to-day relationship between pain and affect of older adults without severe illnesses and to what extent this association differs within and between individuals. A total of 224 participants (M_age = 77.6, SD_age = 6.2) reported their daily experience of pain, impairment by their pain and affect during 21 consecutive days. Multilevel modeling results showed that on days with increased pain individuals also reported less positive affect and more negative affect. Time-lagged results indicated a temporal carry-over from yesterday's pain to today's negative affect but not to today's positive affect. Moreover, on days when individuals reported stronger impairment by their pain, they showed a stronger within-person coupling between daily pain and affect in contrast to days with a weaker experience of daily impairment. Yesterday's pain and today's negative affect were more strongly associated within individuals who reported higher levels of impairment. Interindividual differences in the within-person coupling between daily pain and affect were found with regard to general physical health conditions and general satisfaction with health. This study demonstrated the importance of focusing on within-person couplings between daily pain and affect beyond patient samples in order to better understand the maintenance of emotional stability despite daily hassles in older adults' everyday lives.
