Sleep and sleep-wake disturbances in care recipient-caregiver dyads in the context of a chronic illness: a critical review of the literature

Caregiver Experiences With an Internet-Delivered Insomnia Intervention: SHUTi-CARE Trial Primary Qualitative Analysis

BACKGROUND

Digital health interventions show potential to increase caregivers' access to psychosocial care; however, it is unclear to what extent existing interventions may need to be tailored to meet caregivers' unique needs.

PURPOSE

This study aimed to determine whether-and if so, how-an efficacious Internet-delivered insomnia program should be modified for caregivers. The generalizability of these findings beyond the tested program was also examined.

METHODS

Higher-intensity family caregivers (N = 100; age M = 52.82 [SD = 13.10], 75% non-Hispanic White, 66% ≥college degree) received access to an Internet-based cognitive-behavioral therapy for insomnia (CBT-I) program. Participants who completed one or more intervention "Cores" provided open-ended feedback on their experience; nonusers (completed no Cores) shared their barriers.

RESULTS

Most caregivers who used the program (n = 82, 82%) found it feasible, citing its user-friendly, fully automated online format. Many reported that CBT-I strategies were helpful, although some faced challenges in implementing these strategies due to the unpredictability of their caregiving responsibilities. Opinions were divided on the utility of tailoring the program for caregivers. Nonusers (n = 18, 18%) primarily cited concerns about time burden and lifestyle compatibility as usage barriers.

CONCLUSIONS

Delivering fully automated behavioral interventions through the Internet appears suitable for many caregivers. Extensive tailoring may not be required for most caregivers to benefit from an existing online CBT-I program, although additional guidance on integrating CBT-I strategies in the context of challenging sleep schedules and environments may help a subset of caregivers. Future research should explore how such tailoring may enhance digital health intervention uptake and effectiveness for caregivers.

Caregivers' Internet-Delivered Insomnia Intervention Engagement and Benefit: SHUTi-CARE Trial Primary Quantitative Analysis

BACKGROUND

Delivering insomnia treatment by the Internet holds promise for increasing care access to family caregivers, but their ability to adhere to and benefit from such fully-automated programs has not been rigorously tested.

PURPOSE

This fully-powered, single-group trial tested whether characteristics of the caregiving context influence high-intensity caregivers' engagement with and benefit from an empirically validated Internet intervention for insomnia.

METHODS

At baseline, caregivers providing unpaid time- and responsibility-intensive care who reported insomnia (N = 100; age M = 52.82 [SD = 13.10], 75% non-Hispanic white, 66% ≥college degree) completed questionnaires about caregiving context and sleep, then 10 prospectively-collected online daily sleep diaries. Caregivers then received access to SHUTi (Sleep Healthy Using the Internet), which has no caregiver-specific content, for 9 weeks, followed by post-assessment (questionnaires, diaries). Engagement was tracked by the SHUTi delivery system.

RESULTS

Sixty caregivers completed SHUTi, 22 initiated but did not complete SHUTi, and 18 did not initiate SHUTi. Caregivers were more likely to use SHUTi (than not use SHUTi) when their care recipient (CR) had worse functioning, and were more likely to complete SHUTi when supporting more CR activities of daily living (ADL; ps < .03). Higher caregiver guilt, more CR problem behaviors, and being bedpartners with the CR related to more improved sleep outcomes, whereas supporting more CR instrumental ADL related to less improvement (ps < .05).

CONCLUSIONS

Factors associated with greater caregiving burden, including greater CR impairment and caregiving guilt, were generally associated with better engagement and outcomes. Caregivers with substantial burdens can adhere to and benefit from a fully automated insomnia program without caregiver-specific tailoring.

Sleep Deficiency by Caregiving Status: Findings From Nationally Representative Data

OBJECTIVE

Caregiving demands may influence caregivers' sleep duration and quality, which are essential for optimal health. We aimed to examine the association between caregiving status and sleep deficiency (i.e., short sleep duration and/or poor quality) and identify factors associated with sleep deficiency among caregivers.

METHODS

This secondary analysis used data from 3870 adults living in the United States, obtained from the 2019 Health Information National Trends Survey. Multinomial logistic regressions were performed to examine the association between caregiving status (i.e., caregivers vs. non-caregivers) and sleep status (i.e., normal duration-good quality [optimal sleep, reference], short duration-good quality, normal duration-poor quality, and short duration-poor quality), and to identify caregiving-related factors associated with sleep deficiency in the caregiver group.

RESULTS

Compared to non-caregivers, caregivers were more likely to report short sleep duration (<7 hours) with good quality sleep (relative risk ratio [RRR] = 1.566, 95% CI [1.238, 1.980]) or poor quality sleep (RRR = 1.376, 95% CI [1.034, 1.832]) than the optimal sleep status. Caregivers providing care for ≥20 hours per week (vs. <20 hours) and providing care to individuals with dementia (vs. no dementia caregiving) were 2.8 times more likely to report normal sleep duration with poor sleep quality than optimal sleep (RRR = 2.796, 95% CI [1.125, 6.950]; RRR = 2.776, 95% CI [1.154, 6.675], respectively).

CONCLUSION

The findings of a higher risk of sleep deficiency among caregivers suggest that health care providers need to assess both caregivers' sleep duration and quality status. Interventions tailored to the caregiving context are also warranted.

Partner Alliance to Enhance Efficacy and Adherence of CBT-I

Cognitive behavioral therapy for insomnia (CBT-I) is now widely recognized as the first-line management strategy for insomnia, both for insomnia in its "pure" form, and when comorbid with a physical or psychological illness. However, there is a definite need to develop and test both alternative and adjunct interventions to CBT-I, before implementing them into routine practice. The aim of this article is to provide a narrative review of the literature with regard to what is known about the influence of partners on sleep, insomnia, and its management.

The Caregiver Burden Inventory as a Sleep Disturbance Screening Tool for Parents of Children with Autism Spectrum Disorder

PURPOSE

The study was conducted to explore the degree to which caregiver burden is associated with sleep quality in parents of children with autism spectrum disorder, and to determine a statistically valid cutoff score for the Caregiver Burden Inventory (CBI) in order to identify parents of risk of poor sleep quality.

DESIGN AND METHODS

We conducted a cross-sectional analysis. We assessed caregiver burden with the CBI, sleep quality with the Pittsburgh Sleep Quality Index, emotional status with the Hospital Anxiety and Depression Scale, and impact on family with the Impact on Family Scale. Caregiver burden was evaluated with a logistic regression analysis. The best fit model was used in a receiver operating characteristic analysis. Likelihood ratios and post-test probabilities were calculated.

RESULTS

A total of 116 parents were included in this study. Higher caregiver burden was associated with a reduction in sleep quality in the logistic regression analysis (p < 0.001). The area under the curve for the univariate burden test model (best fit) was 76.70 (p < 0.001). The cutoff score for poor sleep quality was caregiver burden ≥26.50. The post-test probability of poor sleep quality increased to 82.02% from a pre-test probability of 76.72%.

CONCLUSIONS

Our findings suggest that caregiver burden is associated with sleep quality among parents of children with autism spectrum disorder. The findings suggest that a CBI cutoff score of 26.50 may help to detect risk of poor sleep quality in parents of children with autism spectrum disorder.

Interventions that Improve Sleep in Caregivers of Adult Care-Recipients: A Systematic Review

The purpose of the present review was to compile and analyze all interventions aimed at improving the sleep-rest pattern of adult caregivers. A database search was performed in PubMed, Embase, Scopus, CINAHL and PsycINFO. Twenty-four papers published between 1998 and 2020 met the inclusion criteria. Informal caregivers can benefit from various types of sleep interventions, including (a) cognitive-behavioral sleep interventions (CBIs), (b) caregiver health interventions (CHIs), and (c) exercise programs. Other types of interventions such as acupressure, back massage, reflexology, music, and heart rate variability biofeedback sessions may have beneficial effects on the sleep of caregivers. Yet, studies on this topic are heterogeneous and often have considerable methodological shortcomings. Few clinical trials have explored sleep problems as a dyadic caregiver-patient relationship. It is necessary to conduct new clinical trials to determine the viability and level of evidence of the various strategies aimed at improving sleep of informal caregivers.

Do emotional distress and functional problems in persons with traumatic brain injury contribute to perceived sleep-related impairment in caregivers?

OBJECTIVE

The goal of this study was to examine the association between characteristics of persons with traumatic brain injury (PwTBI) and perceived sleep-related impairment of the caregivers.

METHOD

Fifty-two dyads (n = 23 civilians, n = 29 service members/veterans [SMVs]) were enrolled. Caregivers completed the Patient-Reported Outcomes Measurement Information System Sleep-Related Impairment computer adaptive test, and PwTBI completed Quality of Life in Neurological Disorders measures of depression, anxiety, anger, cognitive functioning, and upper and lower extremity functioning. Hierarchical linear regression models, stratified by civilian/SMV group, were employed to assess prediction of caregiver-perceived sleep-related impairment from emotional distress of the PwTBI (anxiety, depressed mood, and anger) and perceived functional status of the PwTBI (cognitive, upper extremity, lower extremity functioning).

RESULTS

Compared with caregivers of civilians, caregivers of SMVs reported higher perceived sleep-related impairment. Regression results showed that characteristics of the PwTBI accounted for moderate amounts of variance in the sleep-related impairment of caregivers of both civilians and SMVs. Within-group analyses showed that the strongest predictor of sleep-related impairment of caregivers of civilians was self-reported cognitive function of the PwTBI (β = -0.82, p = .08); the strongest predictor of sleep-related impairment of caregivers of SMVs was self-reported anger of the PwTBI (β = 0.54, p = .07).

CONCLUSIONS

In both caregivers of civilians and SMVs with TBI, characteristics of the PwTBI were related to perceived caregiver sleep-related impairment. These preliminary data can inform future research with larger samples that examine the impact of multiple characteristics of the caregiver and care recipient on caregiver sleep. Findings highlight the potential importance of considering the dynamics of the dyad in rehabilitation programming not only for the PwTBI but for caregivers as well.

Short self-reported sleep duration among caregivers and non-caregivers in 2016

INTRODUCTION

Caregiving, providing regular care or assistance to family members or friends with health problems or disabilities, may affect caregivers' sleep. This study examined self-reported short sleep duration by caregiving status among US adults.

METHODS

Data of 114,496 respondents aged ≥18 years in 19 states, the District of Columbia, and Puerto Rico from the 2016 Behavioral Risk Factor Surveillance System were analyzed. Prevalence of short sleep duration (<7 hours per 24-hour period) by caregiving status was calculated, and adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs) were derived from a multivariable logistic regression model with adjustment for potential covariates.

RESULTS

Nearly 1 of 5 adults reported caregiving within the past month. A higher prevalence of short sleep duration was reported among caregivers (39.5%) than among non-caregivers (34.2%, adjusted PR [95% CI] = 1.12 [1.06-1.19]). Caregivers who reported prolonged caregiving (≥5 years) reported a higher prevalence of short sleep duration than those with <2 years of caregiving. Similarly, caregivers who provided 20-39 hours of caregiving per week reported a higher prevalence of short sleep duration than those with <20 hours caregiving per week.

CONCLUSIONS

Caregivers had a higher prevalence of short sleep duration than noncaregivers. Providing information and community-based resources and supports for caregiving may minimize caregiver stress and improve sleep particularly for those with prolonged or more intense caregiving.

Dyadic effects of distress on sleep duration in advanced cancer patients and spouse caregivers

OBJECTIVE

Short sleep duration is a common problem for both advanced cancer patients and their spouse caregivers. Sleep and distress have been shown to be interdependent in patient-caregiver and spouse dyads, yet virtually, no work has explored the dyadic effects of psychological distress on sleep in advanced cancer patients and spouse caregivers. The goal of the present study was to examine the dyadic impact of anxiety and depression on sleep duration in a sample of advanced cancer patients and their spouse caregivers. It was hypothesized that, for both patients and caregivers, anxiety and depression in individuals would be associated with sleep duration in both themselves (actor effects) and in their spouses (partner effects).

METHOD

Advanced cancer patients and their spouse caregivers (N = 87 dyads) completed cross-sectional questionnaires assessing demographic variables, subjective health, subjective sleep duration, and anxiety and depression symptoms.

RESULTS

Controlling for sex, age, and subjective health, individuals' anxiety was negatively associated with their own and their partner's sleep duration. No significant actor or partner effects were found for depression.

CONCLUSIONS

Results provided partial support for hypotheses. Although past work has demonstrated links between subjective sleep disturbance and anxiety/psychological distress, this is one of the first studies to examine partner effects of distress on sleep disturbance in advanced cancer patients and spouse caregivers.

Factors Associated with Anxiety and Depression among Family Caregivers of Patients Undergoing Palliative Radiotherapy

Objective:

The family caregivers of patients receiving palliative care experience high levels of anxiety and depression. The aim of the present study was to investigate the factors associated with family caregivers’ anxiety and depression when caring for patients with advanced cancer in Greece.

Methods:

The sample consisted of 100 patients undergoing palliative radiotherapy and their respective caregivers. Patients completed the Hospital Anxiety and Depression Scale (HADS) and the MD Anderson Symptom Inventory. Their respective caregivers completed the Oberst Caregiving Burden Scale, the Bakas Caregiving Outcomes Scale, and the HADS. Correlational and multiple regression analyses were conducted to identify potential predictors of anxiety and depression.

Results:

The majority of patients were male (63.0%), whereas the majority of their caregivers were female (76.0%). The mean ages of patients and caregivers were 63.9 ± 10.8 and 53.3 ± 12.6 years, respectively. Caregiving anxiety and depression were associated with patients’ variables, such as gender (P < 0.0005), primary cancer (P = 0.008), and past surgery (P = 0.002), and caregiver's variables, such as gender (P = 0.001), co-residence (P = 0.05), previous care experience (P = 0.04), and means of transport (P = 0.038). In multiple regression analyses, caregiving anxiety and depression were significantly predicted by caregivers’ and patients’ characteristics, in a model that accounted for 48% of the anxiety variance (P < 0.0005) and 39% of the depression variance (P < 0.0005).

Conclusion:

The caregivers who experienced more anxiety and depression shared the following traits: they were women, cared for men with lung cancer, cared for patients not undergoing surgery, lived together, were younger, went to the hospital by private means of transport, had previous care experience, and perceived an increased degree of general burden. Further investigation of the factors that may affect caregivers’ psychological state is required to better identify parameters that may predict it.

Sleep and Caregiving Experiences among Caregivers of Veterans in an Adult Day Health Care Program: A Pilot Study

OBJECTIVES

This pilot study explored caregivers' attitudes toward core elements of a behavioral sleep intervention for managing sleep problems of older veteran care recipients and the caregivers, as an initial step for developing a dyadic sleep intervention program.

METHODS

Five caregivers (all women; age range, 66-75 years) participated in a focus group discussion. Data were collected at one Veterans Affairs, adult day health care program.

RESULTS

Caregivers' poor sleep was not necessarily explained by their caregiving responsibility. Caregivers felt that behavioral recommendations regarding sleep compression scheduling, increased indoor physical activity, and outdoor light exposure would be acceptable sleep interventions for themselves and the care recipients. Some challenges to the sleep recommendation were identified and they included limiting naptime of care recipients and change of their current sleep schedule.

CONCLUSIONS

Caregivers are receptive to some key components of behavioral approaches to improving sleep. Tailored sleep recommendation strategy is needed to address potential challenges.

CLINICAL IMPLICATIONS

If available within clinical care settings or delivered at the patient's home, caregivers of older veterans are likely to engage in behavioral sleep intervention programs.

Alterations and Interdependence in Self-Reported Sleep-Wake Parameters of Patient-Caregiver Dyads During Adjuvant Chemotherapy for Breast Cancer

PURPOSE/OBJECTIVES

To longitudinally explore changes, similarities, differences, and interrelations in the sleep-wake parameters of patient-caregiver dyads throughout adjuvant chemotherapy for breast cancer.
.

DESIGN

Observational, repeated-measures, dyadic study.
.

SETTING

Four ambulatory oncology clinics in Scotland.
.

SAMPLE

48 dyads consisting of patients and their primary informal caregivers.
.

METHODS

Four dyadic, self-reported sleep-wake assessments took place before chemo-therapy (T0), during chemotherapy cycles 1 (T1) and 4 (T2), and after chemotherapy (T3). Dyads completed the Pittsburgh Sleep Quality Index. Multilevel hierarchical linear modeling was used to explore dyadic data.
.

MAIN RESEARCH VARIABLES

Perceived sleep quality, sleep onset latency (SOL), total sleep time, habitual sleep efficiency, wake after sleep onset, daily disturbance, daytime napping duration, overall sleep-wake impairment.
.

FINDINGS

The majority of dyads had at least one poor sleeper throughout the study; 25%-35% were dyads of concurrent poor sleepers. Curvilinear patterns of change were evident for patients' (but not caregivers') sleep-wake parameters, steadily deteriorating from pre- to midtreatment, then leveling off close to baseline. Average trajectories were significantly different between the dyad members but indicative of a trend for concurrent deterioration at T2. Dyad members' perceived sleep quality, SOL, and overall sleep-wake impairment were closely interrelated; wake variables remained uncoupled.
.

CONCLUSIONS

Despite overall differences in magnitude, sleep problems may be concurrently present in both dyad members, covary, and peak midway through chemotherapy. 
.

IMPLICATIONS FOR NURSING

Dyadic sleep assessments can shed light on potential areas of sleep interaction to enable interventions to support care dyads at risk of sleep distress during chemotherapy for breast cancer.

The relationship of health behaviors with sleep and fatigue in transplant caregivers

OBJECTIVE

The burden and psychological impact of providing care to a loved one with cancer is significant and associated with a number of problems including sleep disturbance and fatigue. While engaging in healthy behaviors such as proper nutrition, exercise, and stress reduction may improve sleep and fatigue, few studies have focused on this relationship. The objective of this study is to examine the relationship of health behaviors with sleep quality and fatigue in transplant caregivers.

METHODS

Data were analyzed from a cross-sectional survey of 78 caregivers of patients undergoing allogeneic hematopoietic stem cell transplantation. Measures included: Health-Promoting Lifestyle Profile II (HPLP-II), Brief Symptom Inventory (Distress), Caregiver Reaction Assessment (Caregiver Burden), Pittsburgh Sleep Quality Index, and the Multidimensional Fatigue Symptom Inventory Short-Form.

RESULTS

Controlling for age, gender, BMI, burden and distress, health behaviors predicted sleep quality (B = -0.408, p = 0.021) and fatigue (B = -0.966, p < 0.001). Stress management (B = -0.450, p = 0.001), nutrition (B = -0.249, p = 0.048), and interpersonal relationships (B = -0.319, p = 0.049) were the HPLP-II subscales that significantly predicted sleep quality; nearly every HPLP-II subscale predicted fatigue.

CONCLUSIONS

Despite the burden and distress associated with caregiving, engaging in healthy behaviors may help to improve sleep and fatigue in transplant caregivers. Published 2015. This article is a U.S. Government work and is in the public domain in the USA.

Sleep Quality in Family Caregivers of Individuals With Dementia

Poor sleep quality in family caregivers may impact their health status and cause quality of life to decline. Nurses are conducting an increasing number of studies that use sleep quality or related concepts as a main indicator to assess caregiver’s sleep. Therefore, a clear understanding of sleep quality and how it is different from other relevant sleep domains is essential. This article aimed to analyze the concept of sleep quality using the steps outlined by Walker and Avant. Findings include (a) attributes of sleep quality including subjective perception of sleep, sleep hours, and evaluation of activity after awaking; (b) antecedents of sleep quality including the ability to get naturally into the sleep cycle and status of conscious state; and (c) consequences of sleep quality including bio-psycho-social and global dimensions of health. This article intends to help clinicians and researchers better understand and define sleep quality in dementia caregivers.

Factors related to caregiving for individuals with spinal cord injury compared to caregiving for individuals with other neurologic conditions

CONTEXT/OBJECTIVE

To compare outcomes among caregivers of adults with spinal cord injuries (SCIs) to caregivers of adults with other neurological conditions, and determine if caregiving for SCI is associated with poor health status and chronic conditions.

DESIGN

Secondary data analysis of 2009/2010 Behavioral Risk Factor Surveillance System survey.

PARTICIPANTS

Informal caregivers of adults with neurological conditions.

OUTCOME MEASURES

Sociodemographics, caregiving factors (e.g. role, emotional support, life satisfaction), lifestyle behaviors, chronic conditions, and health status.

RESULTS

Demographics and lifestyle behaviors did not differ in caregivers of adults with SCI vs. caregivers of adults with other neurological conditions (except younger age of SCI caregivers). Greater proportions of caregivers of adults with SCI had coronary heart disease (CHD) (12% vs. 6%, P = 0.06) and were obese (43% vs. 28%, P = 0.03). Frequent physical distress was reported by 20% of caregivers of persons with SCI (vs. 12% of other caregivers, P = 0.09), but mental health did not differ between caregiver groups. A greater proportion of caregivers of adults with SCI experienced insufficient sleep (47% vs. 30%, P = 0.008) and more days without enough sleep (13 vs. 9 days, P = 0.008). Odds of being younger, caregiver of a spouse, having CHD, and being obese were associated with being a caregiver of an adult with SCI.

CONCLUSION

Caregivers of adults with SCI report similar mental health status, but more poor sleep, and have increased odds of CHD and obesity. Interventions to address physical distress, improve sleep, and address CHD and obesity are needed in this cohort.

Sleep disturbances and related factors among family caregivers of patients with advanced cancer

OBJECTIVE

Sleep disturbances among family caregivers (FCs) are common in advanced cancer. The comprehensive factors for sleep disturbances among the FCs of patients with cancer have not been investigated in Taiwan. The purposes of this study were to investigate the sleep disturbances among the FCs of patients with advanced cancer and to determine predictors of sleep disturbance.

METHODS

A descriptive, cross-sectional study was conducted among 172 FCs. Data were collected using the Pittsburgh Sleep Quality Index and wrist actigraphy. A linear regression model was used to identify the predictive factors for sleep quality.

RESULTS

Seventy-six percent of the FCs experienced some sleep disturbances. Female gender, more fatigue, greater depression, more caregiving burden, and spending over 16 h per day on caregiving tasks were risk factors for sleep disturbances in caregivers.

CONCLUSIONS

Sleep disturbances were common among the Taiwanese FCs of patients with advanced cancer. FCs with risk factors for sleep disturbances should be identified and provided assistance.
