Social networks of older patients with advanced cancer: Potential contributions of an integrated mixed methods network analysis

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.

Marital Status, Living Arrangement, and Survival among Individuals with Advanced Prostate Cancer in the International Registry for Men with Advanced Prostate Cancer

BACKGROUND

Studies have shown improved survival among individuals with cancer with higher levels of social support. Few studies have investigated social support and overall survival (OS) in individuals with advanced prostate cancer in an international cohort. We investigated the associations of marital status and living arrangements with OS among individuals with advanced prostate cancer in the International Registry for Men with Advanced Prostate Cancer (IRONMAN).

METHODS

IRONMAN is enrolling participants diagnosed with advanced prostate cancer (metastatic hormone-sensitive prostate cancer, mHSPC; castration-resistant prostate cancer, CRPC) from 16 countries. Participants in this analysis were recruited between July 2017 and January 2023. Adjusting for demographics and tumor characteristics, the associations were estimated using Cox regression and stratified by disease state (mHSPC, CRPC), age (<70, ≥70 years), and continent of enrollment (North America, Europe, Other).

RESULTS

We included 2,119 participants with advanced prostate cancer, of whom 427 died during up to 5 years of follow-up (median 6 months). Two-thirds had mHSPC. Most were married/in a civil partnership (79%) and 6% were widowed. Very few married participants were living alone (1%), while most unmarried participants were living alone (70%). Married participants had better OS than unmarried participants [adjusted HR: 1.44; 95% confidence interval (CI): 1.02-2.02]. Widowed participants had the worst survival compared with married individuals (adjusted HR: 1.89; 95% CI: 1.22-2.94).

CONCLUSIONS

Among those with advanced prostate cancer, unmarried and widowed participants had worse OS compared with married participants.

IMPACT

This research highlighted the importance of social support in OS within this vulnerable population.

Loneliness in the presence of others: A mixed-method study of social networks of caregivers of patients with severe mental disorders

BACKGROUND

One in four families has at least one member with a mental disorder and families are the main caregivers in most patients in low and middle-income countries. Caregivers experience disruption in their routine lives, increased responsibilities, increased need for support, and changes in their network. The role of personal support networks in the health and burden of the caregivers is complex and depends on the context, cultural and socioeconomical variables. In this study, we aimed to investigate the personal support network of caregivers of patients with severe mental illness in Iran.

METHODS

By using a mixed-methods design, we focused on the structure and composition of caregiver networks, as well as self-perceived caregiver support.

RESULTS

We found that the support network of caregivers was mostly composed of immediate family members whom themselves were selectively chosen as a result of the multidimensional process of interaction between stigma, availability, and the perceived needs of caregivers. The participants mentioned economic and instrumental supports more frequently than emotional support, probably reflecting their unmet basic needs. Advocacy for providing formal systemic supports to caregivers, as well as interventions that expand caregivers personal support network is recommended.

CONCLUSIONS

Most participants of the study were relatively isolated and had a small network of support, mostly composed of immediate family members. Stigma was a serious source of family distress for caregivers and a limiting factor in social relationships.

The role of social networks in prognostic understanding of older adults with advanced cancer

OBJECTIVES

Explore how older patients utilize their social networks to inform prognostic understanding.

METHODS

In a pilot study of adults (≥65 years old) with advanced cancer, 16 patients completed surveys, social network maps, and semi-structured interviews exploring with whom they preferred to communicate about their illness. Interviews were analyzed using open-coding, and codes were categorized into emergent themes. Social network maps and themes were analyzed via mixed-methods social network analysis (MMSNA). Three case examples with diverse network characteristics and communication patterns were selected for further analysis.

RESULTS

Three overarching themes (i.e., prognostic understanding, social support, and therapeutic alliance) revealed that patients' prognostic understanding was strongly influenced by the quality of the social support patients perceived from members of their social networks. Patients demonstrated prognostic understanding when they reported close relationships and open communication with their network members. Case examples revealed some ways that patients sought information and had better sense of their prognosis when they had supportive social networks.

CONCLUSION

Findings illustrate how understanding social networks may provide information on how older adults with cancer seek, share, and process prognostic information.

Responsive social support serves important functions in clinical communication: Translating perspectives from relationship science to improve cancer clinical interactions

Patient-clinician interactions are critical to patient-centered care, including in cancer care contexts which are often defined by multiple patient-clinician interactions over an extended period. Research on these dyadic interactions has been guided by perspectives in clinical communication science, but the study of clinical communication has not been fully integrated with perspectives on interpersonal interactions from relationship science research. An overlapping concept in both fields is the concept of responsive socialsupport. In this article, we discuss responsiveness as a concept that offers opportunities for connections between these two disciplines. Next, we focus on how relationship science can be applied to research in clinical settings. We discuss how three areas of relationship science define responsiveness and have potential for extension to clinical communication: (1) (in)visibility of social support, (2) attachment orientations, and (3) shared meaning systems. We also discuss how social biases can impede responsiveness and suggest research avenues to develop ideas and understand potential challenges in connecting these two fields. Many opportunities exist for interdisciplinary theory development that can generate momentum in understanding interpersonal processes in cancer care.

Facing epistemic and complex uncertainty in serious illness: The role of mindfulness and shared mind

BACKGROUND

Epistemic uncertainty refers to situations in which available evidence is insufficient or unreliable, often accompanied by complexity due to novel contexts, multifactorial causation, and emerging options (the "unknowable unknown"). It stands in contrast to aleatory uncertainty where probabilities are known, and potential benefits and harms can be calculated and presented graphically (the "knowable unknown").

DISCUSSION

Epistemic uncertainty is common, and encompasses uncertainty about the nature of the illness, whom to entrust with one's care, and one's ability to adapt and cope. Communication about the "unknowable unknown" occurs infrequently and ineffectively, and there is little research on improving communication in the face of epistemic and complex uncertainty. Terror Management Theory (TMT) predicts that in encountering serious illness, people engage in "worldview defense" - suppressing death-related thoughts, affiliating with like-minded others, and developing cognitive rigidity and intolerance of information that challenges their worldview. Mindfulness is associated with diminished defensive worldview reactions and cognitive rigidity, and greater tolerance of ambiguity. Shared mind encompasses shared understanding and affective attunement.

CONCLUSION

For clinicians and seriously ill patients facing epistemic uncertainty, psychologically-informed interventions that promote mindfulness and shared mind offer promise in promoting open discussions regarding prognostic uncertainty, advance care planning, and treatment decision-making.
