Interventions to reduce loneliness in caregivers: An integrative review of the literature

Stress and Loneliness Among Family Caregivers of Older Persons With Cognitive Impairment: The Mediating Role of Social Isolation and the Moderating Role of Personal Mastery

OBJECTIVES

Relatively little attention has been paid to the underlying processes and conditions leading to loneliness among caregivers of older persons with cognitive impairment (PCI). Drawing upon the caregiver stress-process model and the social relationship expectations framework, this study examined the mediating role of social isolation and the moderating role of caregiver personal mastery in the association between PCI memory and behavioral problems and caregiver loneliness.

METHODS

Structural equation modeling was applied to cross-sectional data from 266 caregivers in Singapore.

RESULTS

Caregiver-reported PCI memory and behavioral problems were associated with increased levels of caregiver loneliness. Caregiver social isolation partially mediated the association and caregiver personal mastery moderated the association.

DISCUSSION

Caregivers with low mastery were more likely to experience loneliness due in part to social isolation resulting from their PCI's memory and behavioral problems. Tailored interventions should address caregiver social isolation and foster caregiver personal mastery.

The Depression Anxiety Stress Scale 8: investigating its cutoff scores in relevance to loneliness and burnout among dementia family caregivers

The global trend of advanced aging comes at the cost of amplified onset of age-related diseases. Dementia is a common multifactorial age-related neurodegenerative disorder, which manifests with progressive declines in cognitive functioning and ability to perform activities of daily living. As polices discourage institutionalized care, family members act as primary caregivers and endure increased vulnerability to physical and mental health problems secondary to care-related changes in life routine and relationships. Targeting clinically significant distress at earlier stages through valid brief measures may promote caregivers' wellbeing and dementia care continuity/quality. This study aimed to determine the optimal cutoff score of the Depression Anxiety Stress Scale 8-items (DASS-8) in a convenience sample of 571 European caregivers (Mean age = 53 ± 12 years, Italian = 74.4%, Swiss = 25.6%) through three methods. K-means clustering classified the sample into high- and low-distress clusters based on DASS-8 score of 19. Receiver operator curve (ROC) analysis using 48 and 7 cutoffs of the Zarit Burden Interview (ZBI) and the Three-Item University of California, Los Angeles, Loneliness Scale-version 3 (UCLALS3), revealed two DASS-8 cutoffs (12.5 and 14.5, area under the curve (AUC) = 0.85 and 0.92, p values < .001, 95% CI 0.82-0.88 and 0.89 to 0.94, sensitivity = 0.81 and 0.78, specificity = 0.76 and 0.89, Youden index = 0.57 and 0.67, respectively). Decision modeling produced two DASS-8 cutoffs (9.5 and 14.5) for predicting low and high caregiving burden and loneliness, respectively. According to the median of all DASS-8 cutoffs (14.5) the prevalence of mental distress was 50.8%. Distress correlated with key mental problems such as burnout and loneliness-in path analysis, DASS-8 scores were predicted by the ZBI, UCLALS3, care dependency, and receiving help with care, especially among older, female, and spouse caregivers. Further diagnostic workup should follow to confirm psycho-pathogenicity among caregivers with DASS-8 scores above 14.5. Investigations of the DASS-8 in other countries/populations may confirm the validity of this cutoff score.

Loneliness, psychological distress, and the moderating effect of positive aspects of caregiving among cancer caregivers

PURPOSE

Family caregivers of patients with cancer often experience both loneliness and symptoms of psychological distress, such as anxiety and depression. The purpose of this study was to evaluate the associations between loneliness and anxiety and loneliness and depression among family caregivers of patients with cancer and to investigate whether positive aspects of caregiving can have a moderating effect on these relationships.

METHODS

We conducted a cross-sectional exploratory study using baseline data from an ongoing multisite clinical trial. Multiple linear regression models were used to analyze the relationships between loneliness and psychological distress symptoms and the moderating effect of positive aspects of caregiving. Psychological distress outcomes were measured using PROMIS Short Forms (8a) for Anxiety and Depression.

RESULTS

We identified a significant association between loneliness and symptoms of both anxiety and depression. Positive aspects of caregiving did not significantly moderate the relationship between loneliness and depression or loneliness and anxiety.

CONCLUSION

The results of this study shed new light on the relationship between loneliness and symptoms of psychological distress experienced by family caregivers of cancer patients, providing a better understanding of the impact that recognition of positive aspects of caregiving has on the association between loneliness and psychological distress symptoms. Our findings emphasize the importance of targeting family caregiver loneliness in order to reduce psychological distress among family caregivers of cancer patients.

Psychosocial distress among spouses of persons with dementia before and after their partner's death

BACKGROUND

Spouses of persons living with dementia may face heightened psychosocial distress in the years immediately before and after their partner's death. We compared the psychosocial needs of spouses of partners with dementia with spouses of partners with non-impaired cognition nearing and after the end of life, focusing on loneliness, depression, life satisfaction, and social isolation.

METHODS

We used nationally representative Health and Retirement Study married couples data (2006-2018), restricting to spouses 50+ years old. We included 2098 spouses with data on loneliness and depressive symptoms 2 years before and after the partner's death. We additionally examined a subset of spouses (N = 1113) with available data on life satisfaction and social isolation 2 years before their partner's death. Cognitive status of partners was classified as non-impaired cognition, cognitive impairment not dementia (cognitive impairment), and dementia. We used multivariable logistic regression to determine: 1) the change in loneliness and depression for spouses pre- and post-partner's death, and 2) life satisfaction and social isolation 2 years before the partner's death.

RESULTS

Spouses were on average 73 years old (SD: 10), 66% women, 7% Black, 7% Hispanic non-White, 24% married to persons with cognitive impairment, and 19% married to partners with dementia. Before their partner's death, spouses married to partners with dementia experienced more loneliness (non-impaired cognition: 8%, cognitive impairment: 16%, dementia: 21%, p-value = 0.002) and depressive symptoms (non-impaired cognition: 20%, cognitive impairment: 27%, dementia: 31%, p-value < 0.001), and after death a similar prevalence of loneliness and depression across cognitive status. Before their partner's death, spouses of partners with dementia reported less life satisfaction (non-impaired cognition: 74%, cognitive impairment: 68%; dementia: 64%, p-value = 0.02) but were not more socially isolated.

CONCLUSION

Results emphasize a need for clinical and policy approaches to expand support for the psychosocial needs of spouses of partners with dementia in the years before their partner's death rather than only bereavement.

Factors Influencing Social Isolation among Cancer Patients: A Systematic Review

(1) Background: Social isolation, which has numerous adverse effects on health status, is prevalent among cancer patients. This review proposes to identify the influencing factors of social isolation among cancer patients. (2) Methods: Articles published in English or Chinese from six electronic databases before December 2023 were identified via a systematic search. A manual search was also performed. (3) Results: Twenty-eight studies were identified in this systematic review. The factors associated with social isolation can be summarized into the following categories: demographic characteristics, having cancer, health status, coping, social support and social interaction. Despite the heterogeneity, 20 factors were significantly associated with social isolation, including age, gender, comorbidity burden, education level, residence, medical insurance, occupation status, personality, race, smoking status, having children, not living alone, household income level, marital status, the role of primary caregiver, physical health status, mental health status, social health status, coping styles, and the level of social support and social interaction. (4) Conclusions: The systematic review showed that cancer patients' social isolation was influenced by their demographic characteristics, cancer-related factors, physical condition, psychological status, social health status, coping styles, and level of social support and social interaction. In addition, future group intervention could be considered to improve social isolation.

Loneliness and social isolation among informal carers of individuals with dementia: A systematic review and meta-analysis

OBJECTIVES

This systematic review and meta-analysis aimed to determine the prevalence of loneliness and social isolation among informal carers of individuals with dementia and to identify potential influencing factors.

METHODS

We conducted a comprehensive search across 10 electronic databases, including PubMed, Cochrane, Embase, Web of Science, PsycINFO, CINAHL, Scopus, Chinese Biomedical, China National Knowledge Internet, and WANFANG. Our search strategy covered the inception of the databases up to September 16, 2023, with an updated search conducted on March 8, 2024. Prevalence estimates of loneliness and social isolation, presented with 95% confidence intervals, were synthesized through meta-analysis. Subgroup analyses and meta-regression were employed to explore potential moderating variables and heterogeneity.

RESULTS

The study encompassed 27 research papers involving 11,134 informal carers from 17 different countries. The pooled prevalence of loneliness among informal carers of individuals with dementia was 50.8% (95% CI: 41.8%-59.8%), while the pooled prevalence of social isolation was 37.1% (95% CI: 26.7%-47.6%). Subgroup analyses and meta-regression indicated that various factors significantly influenced the prevalence of loneliness and social isolation. These factors included the caregiving setting, study design, the intensity of loneliness, geographical location (continent), data collection time, and the choice of assessment tools.

CONCLUSIONS

This study underscores the substantial prevalence of loneliness and social isolation among informal carers of individuals with dementia. It suggests that policymakers and healthcare providers should prioritize the development of targeted interventions and support systems to alleviate loneliness and social isolation within this vulnerable population.

Examining the Social Networks Types and Their Effects on Caregiving Experience of Family Caregivers for Individuals With Dementia: A Mixed-Methods Study

Background and Objectives

Social networks are crucial to personal health, particularly among caregivers of individuals with dementia; however, different types of social networks among caregivers of those with dementia and how these differences are associated with caregiver burden and positive appraisal, remain underexamined. This study aims to depict dementia caregivers' social network types, related factors, and impact on caregiving experiences.

Research Design and Methods

A questionnaire-based survey was conducted with a total of 237 family caregivers of individuals with dementia nested additional semistructured interviews conducted with 14 caregivers in Chongqing, China. A quantitative study was designed to collect data on personal and situational information, social networks, caregiver burden, and positive aspects of caregiving. Qualitative data were collected via semistructured interviews. Latent class analysis and multivariate regression analyses were applied to quantitative data, and inductive content analysis to qualitative data.

Results

The 3 social network types-family-limited (n = 39, 16.46%), family-dominant (n = 99, 41.77%), and diverse network (n = 99, 41.77%)-differed in age and sex of caregivers and individuals with dementia, stage of dementia, and caregiving intensity. Caregivers in family-dominant networks had a lower caregiver burden (β= -0.299, p = .003) and greater positive aspects of caregiving (β= 0.228, p = .021) than those in family-limited networks. Three themes-accessibility, reciprocity, and reliance-emerged as facilitators and barriers when asking for support. Caregivers frequently cited the perception of economic, practical, and emotional support, yet reported a lack of adequate formal support from healthcare providers.

Discussion and Implication

Family caregivers of individuals with dementia have different social network types that vary considerably among sociocultural contexts and perceive various types of support from social networks. Solid family networks and diverse social networks are contributors to long-term dementia care.

Purpose in life moderates the relationship between loneliness and caregiving stress among family caregivers of people with mental health problems

OBJECTIVE

Providing care to others can exert a profound impact on caregivers' sense of purpose or meaning in life, thereby reciprocally influencing the caregivers' overall health and well-being. This study aims to investigate whether the sense of purpose in life moderates the association between loneliness and caregiving stress among family caregivers of people with mental health problems.

METHODS

A sample of family caregivers of people with mental health problems (N = 468, 57.1 % female) drawn from the 2020 survey of the Caregiving in the U.S. was investigated. Descriptive statistics, correlation analysis, and a multiple regression with an interaction term were performed.

RESULTS

Higher levels of loneliness were associated with enhanced caregiving stress. Moreover, after demographic and care-related factors were controlled for, the association between loneliness and caregiving stress was moderated by purpose in life; namely, as the sense of purpose in life increased, so did the intensity of the relationship between loneliness and caregiving stress.

CONCLUSION

Reducing loneliness or strengthening the sense of purpose helps alleviate caregiving stress, and lonely family caregivers with a strong sense of purpose deserve extra attention.

Behavioral activation for family caregiver connectedness: Adaptation of an evidenced based intervention

Informal caregivers of older adults with chronic illness have unique barriers to social connection. As the older adult population increases, individualized interventions are urgently needed to address the social disconnection experienced across generations of informal caregivers. Adapting an evidenced-based intervention to target social connectedness and leverage technology-mediated communication may be a promising approach. This article describes the adaptation of the Brief Behavioral Activation Treatment for Depression-Revised intervention using elements of the Framework for Reporting Adaptations and Modifications-Enhanced. Facilitating the comprehensive documentation of modifications made, we discuss the (a) rationale for modifications, (b) timing and approach to modifications, (c) nature of context and content modifications, and (d) fidelity in modifications. The Behavioral Activation for Family Caregiver Connectedness intervention addresses unique barriers to caregiver social connection with individualized value-based plans. Modifications to content and delivery reflect the goal of improving intervention fit in the context of social connectedness experienced by informal caregivers.

Feeling Alone Together: Loneliness in Older Adults with Cognitive Impairment and Their Family Caregivers with Low Mastery

INTRODUCTION

Loneliness in older persons with cognitive impairment (PCI) may beget loneliness in their family caregivers, depending on buffering resources caregivers possess. This study examined the association between loneliness in older PCI and loneliness experienced by their family caregivers, and the moderating role of caregiver mastery in this association.

METHODS

Dyadic data from 135 PCI and their family caregivers in Singapore were analyzed using multivariable regression. Loneliness was measured using a three-item UCLA loneliness scale. Mastery was assessed using a seven-item Pearlin instrument.

RESULTS

Multivariable regression showed that PCI loneliness and caregiver loneliness were weakly associated, taking other covariates into account. Notably, a significant interaction between PCI loneliness and caregiver mastery was observed, indicating that PCI loneliness was associated with caregiver loneliness only when caregivers had low mastery.

CONCLUSION

Lonely PCI may share their feelings of loneliness with their caregivers, and this can lead to loneliness among caregivers if they have low mastery. Promoting caregiver mastery may help reduce caregiver loneliness, directly and indirectly as a buffer against PCI loneliness.

Technology-Based Interventions to Address Social Isolation and Loneliness Among Informal Dementia Caregivers: A Scoping Review

OBJECTIVE

Social isolation and loneliness are major public health concerns. Informal dementia caregivers are particularly vulnerable, as many are older adults themselves and at elevated risk of adverse mental and physical health outcomes. Technology-based interventions could offer accessible, affordable, and convenient solutions. A previous review included Internet-based supportive interventions for informal dementia caregivers published up to 2013; however, new publications, technological advances, and targeted outcomes justify conducting this scoping review. Here, we identified and synthesized recent technology-based interventions that addressed social isolation and loneliness among informal dementia caregivers.

DESIGN

Scoping review.

SETTING AND PARTICIPANTS

Informal dementia caregivers in the community.

METHODS

Following Arksey and O'Malley's scoping review framework, we conducted a systematic search of peer-reviewed studies across 6 databases within the last 11 years, including identifying research questions, selecting relevant studies, charting data, and summarizing results.

RESULTS

From the 2937 articles identified, 10 eligible studies were included in this review. The intervention type, format, and duration varied widely. Three categories of interventions to address social isolation and loneliness among informal dementia caregivers included technology-assisted peer support, newly developed Web-based multicomponent psychoeducational programs and platforms, and virtual adaptation and modification of existing programs. Predominantly qualitative evidence suggests that technology-based interventions have the potential to reduce feelings of loneliness and improve caregiver well-being. Quantitative evidence tends to be preliminary and inconclusive.

CONCLUSIONS AND IMPLICATIONS

The findings offer preliminary evidence for technology-based interventions to reduce or prevent social isolation and loneliness in informal dementia caregivers. Technology-based interventions addressing social isolation and loneliness in informal dementia caregivers have the potential to overcome barriers to low uptake of services and withdrawal from interventions and improve the sustainability of the interventions. In the long run, by reducing or preventing social isolation and loneliness in informal dementia caregivers, the transition from home care to facility-based care might be delayed.

Lonely in a Crowd: Social Isolation Profiles and Caregiver Burden Among Family Caregivers of Community-Dwelling Older Adults With Cognitive Impairment

Objectives

This study identified distinct social isolation profiles among caregivers, each formed by varied combinations of social disconnectedness and loneliness, and examined if and how the profiles were associated with caregiver burden.

Methods

Latent class analysis and multivariable regression were applied to data from 266 caregivers of community-dwelling older Singaporeans with cognitive impairment.

Results

Two caregiver social isolation profiles were identified: strongly connected, not lonely (86%), and moderately connected, lonely (14%). Moderately connected and lonely caregivers tended to perceive a higher level of burden than strongly connected and not lonely caregivers. Moderately connected and lonely caregivers were also more likely to be burdened by their care recipients’ poor health than their connected and not lonely counterparts.

Discussion

Caregivers who feel “lonely in a crowd” are vulnerable to caregiving stress and burden. Tailored interventions, such as cognitive behavioral therapy, are needed to reduce the loneliness of moderately connected caregivers.

Interventions and strategies to improve social support for caregivers of children with chronic diseases: An umbrella review

BACKGROUND

Social support is an important approach to improve the psychosocial health status and promote positive coping for caregivers of children with chronic diseases. Such an approach can reduce parenting stress, help resolve parenting difficulties through the use of various social support relationships.

METHODS

We performed an umbrella review methodology using the method of examination, analysis and synthesis of systematic reviews. A PRISMA flow diagram was used to show the search process. The Joanna Briggs Institute was used to appraise the quality of papers and a narrative synthesis was undertaken. Relevant English and Chinese systematic reviews were searched in Embase, PubMed, Web of science, OVID, CNKI, CBM, Wan Fang and Cochrane Library databases, until November 2021, June 2022.

RESULTS

Out of 1,905 records, we included fourteen systematic reviews for a synthesis. Evidence to promote social support for caregivers of children with chronic diseases was identified from four key aspects: (i) Intervention content; (ii) Intervention forms; (iii) Intervention time; and (iv) Sources of support.

CONCLUSIONS

The findings of this review suggest that a combination of differing interventions, especially for early family, including the content of parenting training or education, attitude building and resource provision, which can implement online is recommend. More interventional studies and quantitative evidence syntheses are still needed.

IMPACT

Adequate social support is essential to promote the psychological wellbeing of caregivers of children with chronic diseases. In the early stage of children's diseases, integrating different content and forms of interventions for caregivers' families and actively helping caregivers to identify available support resources can improve social support. The findings from this review can be used to guide caregivers of children with chronic diseases and provide evidence for healthcare professionals and social workers to carry out relevant interventions.
