Social Relationships and Functional Impairment in Aging Cancer Survivors: A Longitudinal Social Network Study

Restricted life-space mobility impacts physical but not mental quality of life in older cancer survivors

BACKGROUND

Older cancer survivors often value quality of life (QOL) over survival. Life-space mobility (LSM), defined as the individual's spatial geographic mobility range, is an important QOL indicator in older adults with chronic illnesses; however, this relationship is unexplored in older cancer survivors.

METHODS

We examined the longitudinal associations and causal relationships between LSM and QOL in 153 older cancer survivors (≥65 years) from the University of Alabama at Birmingham (UAB) Study of Aging. LSM was assessed using the UAB Life-Space Assessment-Composite score (LSA-C), and QOL was assessed by the SF-12 Mental Component Score (MCS12) and Physical Component Score (PCS12) at 0 (study entry), 6, 18, 36, 54, and 72 months. We examined the causal relationship between LSM and QOL using a cross-lagged panel model (CLPM).

RESULTS

The cohort (n = 153) was 76 years old on average and predominantly White (58%), female (58%), and married (55%). Longitudinal analyses found LSM decreased over time (p < 0.0001), and this decrease was associated with decreased QOL (PCS12, p < 0.0001, MCS12, p < 0.0001). In the CLPM causal analysis, lower LSM resulted in worse PCS12 (p < 0.001), but not worse MSC12.

CONCLUSIONS

Restricted LSM resulted in worse physical QOL over 72 months in a sample of 153 older cancer survivors. Developing and evaluating interventions to preserve greater LSM could be a promising approach to improving QOL.

Depression among older adults in an urban slum of Raipur city - a community based cross-sectional study

BACKGROUND

Older adults are at risk of chronic, silent depressive changes and the vulnerability of older adults in urban slums of India is rarely exposed. The objective of this study was to estimate the prevalence of depression among the older adults in the urban slums of India and to study the factors associated with it.

METHODS

This was a community based analytical cross-sectional study conducted in Urban Field Practice Area of a tertiary care teaching hospital in Chhattisgarh, India among older adults more than or equal to 60 years of age selected using two stage, simple random sampling. The data was collected in a sample of 400 older adults by face-to-face interview using self-designed, semi-structured and pretested proforma that included validated Hindi version of Geriatric Depression Scale (GDS-15) and analyzed using SPSS v23.

RESULTS

The prevalence of depression among older adults was 51.5% in the present study; with 27%, 12.8% and 11.8% having mild, moderate and severe depression respectively. Number of family members, living status of spouse, emotional attachment to family members, conflict in family, loneliness, social isolation, marginal friendship ties, functional status, physical exercise, active complains and diastolic BP were independent predictors of depression in older adults.

CONCLUSION

Early identification of depression in older adults using GDS-15 and incorporation of social isolation and functionality assessment routinely by healthcare providers for all older adults attending the outpatient departments is the need of the hour. A holistic approach to care of older adults is vital as healthcare providers seek to understand the impact of multiple, complex, interconnected factors on overall health and well-being of older adults.

Social participation during the COVID-19 pandemic in persons with a high risk for a severe course of COVID-19 - results of a longitudinal, multi-center observational study in Germany

Objective

The COVID-19 pandemic has affected how people go about their daily lives, often in various and substantial ways. This study aims to prospectively evaluate the changes in social participation during the COVID-19 pandemic in persons with a high risk for a severe COVID-19 course in Germany.

Methods

A paper-pencil-based survey was conducted starting at March 2021. Participants filled out questionnaires at four time points based on their COVID-19 vaccination status: before COVID-19 vaccination, one month, six months and twelve months after COVID-19 vaccination. Social participation measures included the Pandemic Social Participation Questionnaire (PSP-Q) and the Index for measuring participation restrictions (IMET). Repeated measures ANOVA and paired t-test were used to test for changes between time-points. Repeated measures correlation was used to assess the relationship between social participation and local COVID-19 incidences.

Results

Data from 245 participants was analyzed before and one month after COVID-19 vaccination. In addition, data from 156 participants was analyzed at time points one, six and twelve months after COVID-19. PSP-Q and IMET scores changed significantly after participants received a COVID-19 vaccination. Between one month and twelve months after vaccination, social participation improved significantly measured by PSP-Q. Social participation was negatively correlated with regional COVID-19 incidences before and after COVID-19 vaccination. Social participation was positively correlated with COVID-19 incidences between one month and twelve months after COVID-19 vaccination.

Conclusions

Social participation improved in persons with a high risk for a severe COVID-19 course during the pandemic. The local COVID-19 incidence showed a negative association with social participation only until the fall of 2021 when it was used as the sole metric to regulate COVID-19 protective measures. Although our data describes the trends in social participation, further studies are needed to identify the influencing factors for the observed increase in social participation.

How effective is peer-to-peer support in cancer patients and survivors? A systematic review

PURPOSE

Core components of peer-to-peer (PTP) support for cancer survivors include informational, emotional, and psychosocial aspects. Previous literature on peer support in cancer includes both professionally and peer-led support. Our objective was to summarize studies on the effects of non-professionally led PTP support in cancer.

METHODS

We performed a systematic research on studies in PTP support of adult cancer survivors with an interventional design, comparing outcomes of PTP support against any control. We included all studies with a precise definition of a PTP support, published from January 2000 up to March 2023 in peer-reviewed journals in English or German.

RESULTS

Out of N = 609 identified publications, we were are able to include n = 18 randomized-controlled trials (RCTs) fulfilling our inclusion criteria. Main settings were dyadic support via telephone, face-to-face (FTF), and web-based online support. Most common outcomes were distress, depressive symptoms, anxiety, and quality of life (QoL). Overall, we found only small effects of PTP support on depression/anxiety, coping, or sexual functioning. Beneficial effects associated with the PTP intervention were apparent in particular in BRCA, in FTF settings, and in assessments of cancer-specific QoL outcomes.

CONCLUSION

This review shows that there are a few RCT investigating the effect of PTP support with short-term effects. Overall, there is a need for more RCTs with high methodological standards to evaluate the effectiveness of PTP support.

The role of community cohesion in elderly people during the COVID-19 epidemic: a cross-sectional study

BACKGROUND

Elderly people were regarded as the most impacted and most vulnerable social group during the COVID-19 epidemic. The community environment is vital for their health. The elderly people had to stay home during the implementation of the management and control of the COVID-19 epidemic. They lack resources and suffer from anxiety. Thus, determining environmental factors beneficial for their physical and mental health is very important.

OBJECTIVE

This study aims to assess the association between community cohesion and physical and mental health among elderly people and to identify the related community service and environmental factors that may promote community cohesion.

METHODS

This community-based cross-sectional study was designed during the COVID-19 epidemic. A multistage sampling method is applied to this study. A total of 2,036 participants aged ≥ 60 years were sampled from 27 locations in China. Data were collected through face-to-face interviews. The neighborhood cohesion instrument consisting of three-dimensional scales was used to assess community cohesion. Self-efficacy and life satisfaction, cognitive function and depression, and community service and environmental factors were also measured using standard instruments. Statistical analyses were restricted to 2,017 participants. Separate logistic regression analysis was conducted to assess the association between community cohesion and physical and mental health factors, as well as related community service and environmental factors, among elderly people.

RESULTS

The results showed that high levels of community cohesion were associated with good self-perceived health status and life satisfaction and high levels of self-efficacy and psychological resilience, and their odds ratios (ORs) were 1.27 (95% CI, 1.01-1.59) and 1.20 (95% CI, 1.15-1.27) and 1.09 (95% CI, 1.05-1.13) and 1.05 (95% CI, 1.03-1.06), respectively. The length of stay in the community and the level of physical activity were positively associated with community cohesion scores, whereas the educational level was negatively associated with the community cohesion scores (P < .05). Community cohesion was also associated with low level of depression and high level of cognitive function. The community cohesion was significantly associated with community services and environmental factors from four dimensions. High levels of community cohesion were associated with transportation service, rental of rehabilitation equipment, high levels of satisfaction for community doctors' technical level and community waste disposal, and their ORs were 3.14 (95% CI, 1.87-5.28), 3.62 (95% CI, 2.38-5.52), 1.37 (95% CI, 1.08-1.73), and 1.23 (95% CI, 1.01-1.50), respectively.

CONCLUSIONS

Community cohesion was associated with the physical and mental health of elderly people. Our research suggests that enhancing community services and environmental management may be an effective strategy to increase community cohesion during the epidemic period of major infectious diseases.

CLINICALTRIAL

Tailored Psychological Interventions to Manage Body Image: An Opinion Study on Breast Cancer Survivors

OBJECTIVE

Oncological care affects the body strongly, even some years after therapies. Body image, as the mental representation of one's own body, is particularly affected by breast cancer, with a high level of dissatisfaction and negative perception. Literature has shown the effectiveness of various psychological interventions to promote body image in breast cancer survivors, dealing with inner sensations and related emotions and thoughts. The present opinion study presents BI issues and personalized psychological interventions to increase a positive BI in breast cancer survivors.

CONCLUSIONS

Implementing specific and personalized psychological interventions tailored on BI, the characteristics of oncological journey and emotional and cognitive issues is fundamental. Directions for clinical practice are given.

Social Relationships and Onset of Functional Limitation among Older Adults with Chronic Conditions: Does gender matter?

Objectives

This study aimed to examine the longitudinal association between social relationships and physical functioning among community-dwelling older adults with chronic conditions.

Methods

Self-reported questionnaires were distributed and collected between 2014 and 2017 from participants ≥65 years old. The Index of Social Interaction was used to evaluate social relationships and the instrumental activities of daily living (IADL) subscale of the Tokyo Metropolitan Institute of Gerontology Index of Competence was used to examine functional status.

Results

A total of 422 participants (190 males and 232 females) were included in the final analysis. High social relationships demonstrated significant adverse effects (odds ratio [OR] = 0.77, 95% confidence interval [CI]: 0.64-0.93) on the decline of IADL in the overall sample, particularly for females (OR = 0.71, 95% CI: 0.55-0.93) but not as much for males (P = 0.131).

Conclusion

This finding suggests that functional limitation was influenced by social relationships among disabled older adults and the influence of social relationships on functional limitation differed based on gender.

Modèle de survie au cancer appliqué aux soins holistiques et à la recherche

Les progrès réalisés dans la lutte contre le cancer ont augmenté les taux de survie, entraînant un tel changement de paradigme que le cancer est maintenant considéré comme une maladie chronique; il nous faut donc évaluer notre connaissance de la survie au cancer (SC). C’est dans cette optique que les auteurs ont procédé à une recension exhaustive des écrits dans les référentiels CINAHL, MEDLINE et PUBMED de 2000 et 2021. En s’appuyant sur les concepts étudiés dans la littérature, ils ont répertorié les principaux facteurs qui influencent la survie au cancer dans l’ensemble des populations atteintes et ont proposé un modèle. Le présent article décrit ce modèle de survie au cancer (MSC). Le MSC prend en compte les facteurs prédisposant à la survie ainsi que les facteurs d’influence en jeu dans les trois phases de survie (aiguë, prolongée et permanente), à savoir le traitement et le traitement d’entretien (soins médicaux et psychosociaux), le bien-être, et d’autres éléments d’influence (expériences entraînant de profonds changements, incertitude, établissement de priorités, gestion du bien-être et conséquences indirectes) de même que les facteurs liés aux relations sociales qui jouent sur le fardeau des symptômes des survivants ainsi que l’expérience globale de la survie (état de santé et qualité de vie). Une étude de cas a d’ailleurs montré l’utilité du MSC. L’application du modèle est prometteuse pour l’avenir, tant pour améliorer la qualité de la survivance que pour guider la recherche et la pratique clinique en vue de favoriser et d’optimiser la bonne santé des survivants à long terme.

The role of social networks in the self-management support for young women recently diagnosed with breast cancer

It is widely acknowledged that social network support plays an important role in the quality of life and illness management of breast cancer survivors. However, the factors and processes that enable and sustain such support are less well understood. This paper reports baseline findings from a prospective UK national cohort of 1,202 women with breast cancer (aged <50 years at diagnosis), recruited before starting treatment, conducted in 2016-2019. Descriptive, univariate and multivariate regression analyses explored associations between the individual, and network member characteristics, and the type of support provided. Social network members provided a substantial level of illness-related, practical and emotional support. Highest contribution was provided by friends, followed by close family members. The social network members of women who did not have a partner provided a higher level of support than those in networks with a partner. Women without higher education were more reliant on close family members than those with higher education, and this was more so for women without a partner. Women with higher education without a partner were more reliant on friends and were overall best supported. Women without higher education who did not have a partner were overall least well supported. They had much smaller networks, were highly reliant on close family members, and on high level contributions from all network members. There is a need to develop network-based interventions to support people with a cancer diagnosis, prioritising support for the groups identified as most at risk. Interventions that support engagement with existing network members during treatment, and those that help extend such networks after treatment, are likely to be of benefit. A network perspective can help to develop tailored support and interventions by recognising the interactions between network and individual level processes.

A cancer survivorship model for holistic cancer care and research

Advancements in cancer have increased survival rates leading to a paradigm shift such that cancer is considered a chronic disease, necessitating an evaluation of our understanding of cancer survivorship (CS). For this purpose, a comprehensive literature search was performed, using CINAHL, MEDLINE, and PUBMED from 2000-2021. Drawing from the concepts in the literature, salient factors that affect CS across cancer populations were identified and a proposed model was developed. This paper describes the Cancer Survivorship Model (CSM). The CSM represents predisposing factors for survivors and survivorship's acute, extended, and long-term phases, influencing factors: treatment and maintenance (medical/ psychosocial care), well-being, influencing aspects (life-changing experience, uncertainty, prioritizing life, wellness management, and collateral damage), and social relationship factors that impact survivors' symptom burdens and overall survivorship experience (health outcomes and quality of life). A case study demonstrates the CSM utility. Future application of the model holds promise for improving the quality of survivorship and informing research and clinical practice to promote and optimize survivors' outcomes throughout the evolving survivorship.

Causal Relationships between Personal Networks and Health: A Comparison of Three Modeling Strategies

Prior research documents associations between personal network characteristics and health, but establishing causation has been a long-standing research priority. To evaluate approaches to causal inference in egocentric network data, this article uses three waves from the University of California Berkeley Social Networks Study (N = 1,159) to investigate connections between nine network variables and two global health outcomes. We compare three modeling strategies: cross-sectional ordinary least squares regression, regression with lagged dependent variables (LDVs), and hybrid fixed and random effects models. Results suggest that cross-sectional and LDV models may overestimate the causal effects of networks on health because hybrid models show that network-health associations operate primarily between individuals, as opposed to network changes causing within-individual changes in health. These findings demonstrate uses of panel data that may advance scholarship on networks and health and suggest that causal effects of network support on health may be more limited than previously thought.

Factors associated with functional disability in older adults with cancer treated at reference outpatient clinics in the state of Mato Grosso, Brazil

OBJECTIVE

To analyze factors associated with functional disability in older adults with cancer treated at reference outpatient clinics in the state of Mato Grosso, Brazil.

METHODS

This is a cross-sectional study of 463 older adults aged 60 years or older. The outcome variable was functional disability, evaluated by Lawton and Brody's Instrumental Activities of Daily Living (IADL) scale. The independent variables were sociodemographic characteristics, lifestyle, social support, and health aspects. We performed bivariate and multivariate analyses and calculated prevalence ratios (PR) using Poisson regression with robust variance.

RESULTS

The prevalence of IADL functional disability was 55.3%. The variables associated with this disability in the multivariate analysis were: not working (PR=1.36; 95% confidence interval - 95%CI 1.03-1.78); low (PR=1.49; 95%CI 1.10-2.03) and moderate (PR=1.30; 95%CI 1.04-1.64) perceived affectionate support; depressive symptoms (PR=1.31; 95%CI 1.10-1.56); malnutrition (PR=1.28; 95%CI 1.03-1.59); having two or more comorbidities (PR=1.30; 95%CI 1.03-1.64), and having a companion to health services (PR=1.39; 95%CI 1.05-1.83).

CONCLUSION

In addition to physical health aspects, comorbidities, and malnutrition, functional disability was associated with emotional, social support, and work issues, reinforcing the importance of comprehensive care and actions to maintain and recover functional capacity, promoting a better quality of life, the independence of older adults with cancer, and a reduced risk of adverse biopsychosocial outcomes.

Identification and Determination of Dimensions of Health-Related Quality of Life for Cancer Patients in Routine Care - A Qualitative Study

Purpose

Continuous patient-reported outcomes (PROs) to identify and address patients’ needs represent an important addition to current routine care. The aim of this study was to identify and determine important dimensions of health-related quality of life (HrQoL) in routine oncological care.

Methods

In a cross-sectional qualitative study, interviews and focus groups were carried out and recorded. The interviewees were asked for their evaluation on HrQoL in general and specifically regarding cancer treatment. The material was transcribed and analyzed using qualitative content analysis based on Mayring. The results were reviewed in an expert discussion.

Results

Interviews with patients (N = 28) and clinicians (N = 4), as well as five focus groups with clinicians (N = 18) were conducted. Initially, nine deductive and two inductive categories on HrQoL were built. Four categories (partnership/sexuality, spirituality/religiousness, health perception, and overall health) were excluded following the qualitative content analysis because they were hardly or not at all mentioned by participants. Following on from the analysis of the expert discussion, one dimension was added (dignity), and two further categories were excluded (mobility and feeling of security in treatment). The resulting system consisted of six dimensions: emotional health, physical ailments, autonomy, social functionality, dignity, and resources.

Conclusion

The identified dimensions of HrQoL in routine oncological care were found to differ from those used in existing HrQoL measurements for (cancer) patients. Further research is needed to test and evaluate the presented structure in a larger sample of cancer patients to further assess its psychometric properties.

New directions in cancer and aging: State of the science and recommendations to improve the quality of evidence on the intersection of aging with cancer control

Background

The global population of older cancer survivors is growing. However, the intersections of aging‐related health risks across the cancer control continuum are poorly understood, limiting the integration of aging into cancer control research and practice. The objective of this study was to review the state of science and provide future directions to improve the quality of evidence in 6 priority research areas in cancer and aging.

Methods

The authors identified priority research areas in cancer and aging through an evidence‐based Research Jam process involving 32 investigators and trainees from multiple disciplines and research centers in aging and cancer; then, they conducted a narrative review of the state of the science and future directions to improve the quality of evidence in these research areas. Priority research areas were defined as those in which gaps in scientific evidence or clinical practice limit the health and well‐being of older adults with cancer.

Results

Six priority research areas were identified: cognitive and physical functional outcomes of older cancer survivors, sampling issues in studies of older cancer survivors, risk and resilience across the lifespan, caregiver support and well‐being, quality of care for older patients with cancer, and health disparities. Evidence in these areas could be improved through the incorporation of bias reduction techniques into longitudinal studies of older cancer survivors, novel data linkage, and improved representation of older adults in cancer research.

Conclusions

The priority research areas and methodologies identified here may be used to guide interdisciplinary research and improve the quality of evidence on cancer and aging.

The population of older cancer survivors is growing, yet the effects of aging‐related health risks across the cancer control continuum remain poorly understood. This article identifies research areas that may be used to guide interdisciplinary research and improve the quality of evidence on cancer and aging.

Fatores associados à incapacidade funcional em idosos com câncer atendidos em ambulatórios de referência no estado de Mato Grosso, Brasil

RESUMO: Objetivo: Analisar os fatores associados à incapacidade funcional em idosos com câncer atendidos em ambulatórios de referência do estado de Mato Grosso, Brasil. Métodos: Estudo transversal, com 463 idosos de 60 anos ou mais. A variável desfecho foi a incapacidade funcional, avaliada por meio da Escala de Atividades Instrumentais de Vida Diária (AIVD) desenvolvida por Lawton e Brody. As variáveis independentes foram características sociodemográficas, estilo de vida, apoio social e condições de saúde. Foram realizadas análises bivariada e múltipla, calculando-se as razões de prevalência (RP), com o uso de regressão de Poisson com variância robusta. Resultados: A prevalência de incapacidade funcional para as AIVD foi de 55,3%. As variáveis que se associaram a essa incapacidade na análise múltipla foram: não trabalhar (RP=1,36, intervalo de confiança — IC95% 1,03–1,78); percepção de apoio afetivo baixo (RP=1,49; IC95% 1,10–2,03) e médio (RP=1,30; IC95% 1,04–1,64); sintomas depressivos (RP=1,31; IC95% 1,10–1,56); desnutrição (RP=1,28; IC95% 1,03–1,59); ter duas ou mais comorbidades (RP=1,30; IC95% 1,03–1,64) e ter acompanhante aos serviços de saúde (RP=1,39; IC95% 1,05–1,83). Conclusão: Além das condições de saúde física, comorbidade e desnutrição, as questões emocionais, de apoio social e trabalho associaram-se à incapacidade funcional, reforçando a importância de uma atenção integral e de ações de manutenção e recuperação da capacidade funcional, promovendo maior qualidade de vida, a independência do idoso com câncer e a redução do risco de desfechos adversos em âmbito biopsicossocial.

Cognitive dysfunction prevalence and associated factors in older breast cancer survivors

OBJECTIVES

The purpose of this study was to examine the prevalence and factors associated with objective and subjective cognitive dysfunction in older breast cancer survivors (BCS).

MATERIALS AND METHODS

This cross-sectional descriptive study leveraged previously collected data from older BCS (n = 335). Separate linear regression models were used to determine relationships between demographic factors (age, education), medical factors (comorbidities), disease factors (time since diagnosis, cancer stage), cancer-related symptoms (depressive symptoms, anxiety, fatigue, sleep disturbance) and cognitive dysfunction measures, including objective learning, delayed recall, attention, executive function-working memory, verbal fluency and subjective attentional function.

RESULTS

Cognitive dysfunction was prevalent with up to 18.6% of older BCS experiencing mild-moderate dysfunction (1.5 standard deviations below mean of non-cancer controls) in at least one cognitive domain. Poor to moderate subjective attentional function was reported by 26% of older BCS. More depressive symptoms were significantly related to poorer cognitive function including learning (p < .01), delayed recall (p < .05), verbal fluency (p < .001), and subjective attentional function (p < .001) but not attention and executive function-working memory. Age, education, anxiety, and fatigue were also negatively associated with cognitive function in some models (p < .05-0.001).

CONCLUSION

Cognitive dysfunction is common among older BCS and depressive symptoms, anxiety, and fatigue are related factors. Importantly, depressive symptoms were not only related to self-report, but also to cognitive performance. Healthcare providers should be aware of and assess for related factors and cognitive dysfunction itself in older BCS even years after diagnosis and treatment thorough geriatric assessment. Future longitudinal research is needed to discern these relationships.

Opioid prescribing and risk of drug-opioid interactions in older discharged patients with polypharmacy in Australia

Background Opioids are commonly prescribed to managing chronic pain in older persons. However, these patients are often at risk of drug-opioid interactions due to polypharmacy. Objectives To identify the prevalence of opioid prescribing and drug-opioid interactions in poly-medicated older patients and factors associated with opioid prescribing. Setting Patients were included if they were admitted to the Royal Adelaide Hospital between September 2015 and August 2016, aged ≥ 75 years and took ≥ 5 medications at discharge. Methods After ethics approval, data of were retrospectively collected from case notes. The Charlson Comorbidity Index and Drug Burden Index were determined and opioids were classified as strong or weak. The association between opioid use and concurrent medications was computed using logistic regression and the results presented as odds ratios (OR) and 95% confidence intervals (95% CI), adjusted for age, sex, Charlson Comorbidity Index, number of prescribed medications and modified-Drug Burden Index. Main outcome measure Association between concurrent medications and opioid prescribing. Results 15,000 geriatric admissions were identified, of which 1192 were included. A total of 283 (23.7%) patients were prescribed opioids, with oxycodone accounting for 56% of these prescriptions. Opioid users were prescribed more medications (11.2 vs. 9.0, P < 0.001) and had higher Drug Burden Index (1.2 vs. 0.14, P < 0.001) compared to non-users. Opioid use was associated with concurrent prescription of antiepileptics (OR = 1.7, 95% CI 1.1-2.6), and negatively associated with Charlson Comorbidity Index (OR = 0.9, 95% CI 0.8-0.98) and concurrent use of antipsychotics (OR = 0.5, 95% CI 0.3-0.9) and beta blocking agents (OR = 0.4, 95% CI 0.3-0.6). Conclusions Strong opioids were prescribed more often than weak opioids and opioid users presented with characteristics and concurrent medications which increased the risk of opioid related adverse drug effects.

"They're in My Heart, Mind, and Cells": What Continuing Bonds Reveal About Social Networks

BACKGROUND AND OBJECTIVES

Research suggests that robust social networks have positive effects on peoples' well-being. An instrumental methodology for studying networks is the social convoy model, a diagram of concentric circles that illustrate network size, structure, and satisfaction. Convoys have been described as dynamic. Specifically, as people age, their convoys become stronger and smaller due to focusing on what matters most and accumulating losses. Therefore, convoys only include meaningful, living persons. The continuing bonds model posits that it is normal for people to maintain connections with the deceased. The objective of the current study was to integrate the social convoy and continuing bonds models in order to examine the presence of deceased loved ones in convoys.

RESEARCH DESIGN AND METHODS

Eighteen individuals (M = 66 years), recruited via fliers and snowball sampling, participated in one semistructured interview regarding the death of a loved one and their convoy. Participants also completed a convoy model, identifying where the deceased fit (if anywhere) when they were alive and at present. Interviews were transcribed, coded, and analyzed for themes.

RESULTS

Three themes emerged: communication (i.e., writing or speaking to the deceased), continuity (i.e., a continuing relationship), and reciprocity (i.e., perceived exchange of support(s)). Eighty-nine percent of participants felt their loved one's death did not change their convoy presence and 88% reported that their positioning in the convoy remained unchanged.

DISCUSSION AND IMPLICATIONS

This research offers a new way to think about convoys and may prompt the development of supportive interventions for bereaved individuals.

Leveraging system sciences methods in clinical trial evaluation: An example concerning African American women diagnosed with breast cancer via the Patient Navigation in Medically Underserved Areas study

Background

Systems science methodologies offer a promising assessment approach for clinical trials by: 1) providing an in-silico laboratory to conduct investigations where purely empirical research may be infeasible or unethical; and, 2) offering a more precise measurement of intervention benefits across individual, network, and population levels. We propose to assess the potential of systems sciences methodologies by quantifying the spillover effects of randomized controlled trial via empirical social network analysis and agent-based models (ABM).

Design/methods

We will evaluate the effects of the Patient Navigation in Medically Underserved Areas (PNMUA) study on adult African American participants diagnosed with breast cancer and their networks through social network analysis and agent-based modeling. First, we will survey 100 original trial participants (50 navigated, 50 non-navigated) and 150 of members of their social networks (75 from navigated, 75 non-navigated) to assess if navigation results in: 1) greater dissemination of breast health information and breast healthcare utilization throughout the trial participants’ networks; and, 2) lower incremental costs, when incorporating navigation effects on trial participants and network members. Second, we will compare cost-effectiveness models, using a provider perspective, incorporating effects on trial participants versus trial participants and network members. Third, we will develop an ABM platform, parameterized using published data sources and PNMUA data, to examine if navigation increases the proportion of early stage breast cancer diagnoses.

Discussion

Our study results will provide promising venues for leveraging systems science methodologies in clinical trial evaluation.
