Interdependence of physical and psychological morbidity among patients with cancer and family caregivers: Review of the literature

Overcoming Patient Pain Together: Breast Cancer Patients and Caregivers' Pretreatment Psychosocial Distress Linked to Patients' Pain Interference During the First Year of Treatment

Breast cancer patients experience treatment-related pain from surgery, radiation, chemotherapy, and long-term hormonal treatment, which can lead to poorer outcomes. Patient and family caregivers' psychosocial distress exacerbates patient pain interference, but this has not been directly examined among breast cancer patients in dyadic models longitudinally. Guided by a biopsychosocial framework, the Biobehavioral Family Model, we explore how multiple reports of patient pain interference across the first year of treatment are linked to the patient (N = 55) and caregiver (N = 55) pretreatment psychosocial distress (eg, depression, anxiety, marital satisfaction, family relationship quality). Specifically, we find that breast cancer patients' pain interference increases and then decreases over the first year of treatment. Additionally, caregivers' pretreatment anxiety was associated with increased patient pain interference over time (B = .19, SE = .07, P = .008), while patients' pretreatment psychosocial distress was not associated with a change in their pain interference. Yet, looking at clinically specific times during the first year of treatment, we find that caregiver-reported higher marital satisfaction is associated with lower patient-reported pain interference later in treatment (6 months: B = -.58, SE = .24, P = .017; 12 months: B = -.82, SE = .23, P < .001). We conclude that, per the Biobehavioral Family Model, pretreatment patient and caregiver psychosocial distress is linked to patient pain interference during the first year of breast cancer treatment. Thus, caregivers' psychosocial distress (ie, anxiety and marital satisfaction) may be a particularly important target in future dyadic behavioral intervention strategies to reduce breast cancer patient pain. PERSPECTIVE: This article presents the link between breast cancer patients and family caregiver pretreatment psychosocial distress (anxiety, depression, marital satisfaction, and family quality) on patient pain interference during 1 year of breast cancer treatment. Findings suggest that caregiver anxiety and marital satisfaction may be important targets for future dyadic behavioral pain interventions.

Quality of Life in Patients and Their Spouses and Cohabitating Partners in the Year Following a Cancer Biopsy (the Couples Cope Study): Protocol for a Prospective Observational Study

BACKGROUND

Receiving a diagnosis of cancer is a profound and often very stressful experience. Few studies have prospectively recruited patients prior to receiving a new diagnosis of cancer and included spouses or partners.

OBJECTIVE

The aim of the Couples Cope Study is to understand the impact of undergoing a diagnostic biopsy and receiving a new cancer diagnosis on quality of life (QoL) in both patients and their spouses or partners, as well as on the quality of their relationship. This protocol paper describes the study design and assesses the feasibility of recruitment and retention.

METHODS

Study staff reviewed the schedules of collaborating physicians using specific encounter codes to identify patients scheduled for breast or prostate biopsies. Potential participants were prescreened via the electronic health record and sent a recruitment letter at least 2 to 3 weeks prior to their biopsy procedure. Patients subsequently underwent a phone screening to determine eligibility. Patients who enrolled provided study staff with contact information for their spouses or partners. All consent forms were completed online. Surveys were completed online prior to receiving the biopsy results (baseline), and at 1, 3, 6, and 9 months after the biopsy. Study staff engaged in ongoing, personalized contact with participants and sent assessment completion reminders via phone and email.

RESULTS

A total of 2294 patients undergoing a breast or prostate biopsy were identified and 69% (n=1582) were eligible for phone screening following electronic health record prescreening. Of the 431 patients who underwent phone screening, 75% (n=321) were eligible to participate. Of the eligible patients, 72% (n=231) enrolled and 82% (n=190) of enrolled patients had an accompanying partner or spouse who also enrolled. A total of 77% (34/44) of patients who received a cancer diagnosis and 72% (26/36) of their spouses or partners were retained through 9 months, while 80% (53/66) of patients who received a benign diagnosis and 68% (42/62) of their partners were retained.

CONCLUSIONS

Prospective recruitment of patients undergoing diagnostic biopsy and their partners is feasible and requires both strategic collaboration with providers and concerted prescreening and recruitment efforts by study staff. Importantly, this study was able to conduct all study activities online without disrupting clinical workflow and without requiring patients and their spouses or partners to come into the laboratory. Consideration should be given to the ratio of biopsies to cancer diagnoses, which can vary significantly by cancer type. Prospective studies are needed and can inform our ability to provide effective support earlier to couples facing a possible cancer diagnosis. Future studies should examine other tumor types that have received less attention in QoL studies, include behavioral and neurobiological assessments beyond self-report measures, and follow couples beyond 9 months in order to examine long-term effects on QoL.

Spirituality moderates the relationship between cancer caregiver burden and depression

OBJECTIVES

Cancer has become a chronic disease that requires a considerable amount of informal caregiving, often quite burdensome to family caregivers. However, the influence of spirituality on the caregivers' burden and mental health outcomes has been understudied. This study was to examine how caregiver burden, spirituality, and depression change during cancer treatment and investigate the moderating role of spirituality in the relationship between caregiver burden and depression for a sample of caregivers of persons with cancer.

METHODS

This secondary analysis used a longitudinal design employing 3 waves of data collection (at baseline, 3 months, and 6 months). Family caregivers completed the Caregiver Reaction Assessment, Spiritual Perspective Scale, and the PROMIS® depression measure. Linear mixed model analyses were used, controlling for pertinent covariates.

RESULTS

Spirituality, total caregiver burden, and depression remained stable over 6 months. More than 30% of the caregivers had mild to severe depressive symptoms at 3 time points. There was evidence of overall burden influencing depression. Of note was a protective effect of caregivers' spirituality on the relationship between depression and caregiver burden over time (b = -1.35, p = .015). The lower the spirituality, the stronger the relationship between depression and burden, especially regarding subscales of schedule burden, financial burden, and lack of family support.

SIGNIFICANCE OF RESULTS

Spirituality was a significant resource for coping with caregiving challenges. This study suggests that comprehensive screening and spiritual care for cancer caregivers may improve their cancer caregiving experience and possibly influence the care recipients' health.

Relationship between family resilience and dyadic coping in colorectal cancer patients and their spouses, based on the actor-partner interdependence model

PURPOSE

To explore the relationship between dyadic coping and family resistance in colorectal cancer patients and their spouses.

METHODS

178 pairs of colorectal cancer patients and their spouses hospitalized in a three tertiary hospital in Changsha were selected from July 2021 to March 2022. The Family Resilience Assessment Scale and the Dyadic Coping Inventory were used to investigate, which relationship was analyzed by APIM.

RESULTS

The total score of patients' dyadic coping was 121.51 ± 16.8, and spouses' score was 123.72 ± 16.6. The total score of family resilience was 176.42 ± 16.0, and spouses' score was 182.72 ± 17.03. There was a significant positive relationship between dyadic coping and family resistance of colorectal cancer patients and their spouses (r > 0.7, P < 0.001). The positive dyadic coping of colorectal cancer patients and their spouses had a positive effect on their own and their spouses' family resilience and the effect was the same. The negative dyadic coping of colorectal cancer patients and their spouses had a negative impact on their own family resilience, and the overall model showed a subject pattern.

CONCLUSIONS

The level of family resilience of colorectal cancer patients and their spouses was affected by the level of dyadic coping. Medical workers should regard patients and their spouses as a whole and formulate mutually supportive coping strategies with family as the center, so as to increase positive coping behavior and enhance their family's ability to cope with cancer.

Burden, Depression and Quality of Life in Carers of Newly Diagnosed Advanced Cancer Patients in Egypt

CONTEXT

The goal of palliative care (PC) is to improve the quality of life (QoL) of patients with life-limiting illnesses as well as their families. Ideally, PC is integrated early in the course of life-limiting illnesses. Less attention has been paid to the need for early PC for family caregivers (FCs) in lower-income settings.

OBJECTIVES

This observational cross-sectional study was conducted to explore the burden experienced by FCs of newly diagnosed incurable cancer patients in Egypt and characterize its relation to depression and QoL.

METHODS

Ninety-five adult FCs of adult patients with newly diagnosed incurable cancer completed the 22-item Zarit Burden Interview (ZBI-22), Patient Health Questionnaire (PHQ-9), and Short Form 12 (SF-12) to assess caregiving burden, depression, and QoL among FCs, respectively.

RESULTS

The median (IQR) ZBI-22 score was 17(11-24) and 34% of FCs had significant burden (ZBI-22 score > 20). Assistance with late loss activities of daily living and availability for longer caregiving duration were associated significantly with higher caregiving burdens (P = 0.004 and 0.047, respectively). FCs with significant burden had significantly higher PHQ-9 scores (P = 0.0003). There was a significant negative correlation between ZBI-22 scores and the bodily pain, general health, mental health, physical function, role emotional, and social function subscales/items of SF-12.

CONCLUSIONS

A substantial proportion of Egyptian FCs of incurable cancer patients experience significant burden early in the course of the disease. This burden is associated with depressive symptoms and worse QoL dimensions, physical, psychological, and social. In a lower-income setting, early PC interventions for FCs of incurable cancer patients are needed.

Dyadic Investigation of Posttraumatic Stress Symptoms and Daily Sleep Health in Patients With Cancer and Their Caregivers

OBJECTIVE

Cancer can be a traumatic experience affecting multidimensional aspects of sleep among patients and caregivers. This study examined the differential associations of cancer-related posttraumatic stress symptoms (PTSS) with various sleep markers in this population.

METHODS

Patients newly diagnosed with colorectal cancer ( n = 138, mean age = 56.93 years, 31.88% female, 60.14% Hispanic, 6.53 months after diagnosis) and their sleep-partner caregivers ( n = 138, mean age = 55.32 years, 68.12% female, 57.97% Hispanic) completed questionnaires assessing the four PTSS clusters (intrusion, avoidance, alterations in arousal and reactivity, negative alterations in cognitions and mood). Participants also completed daily sleep diaries for 14 consecutive days, from which sleep onset latency (SOL), wake after sleep onset (WASO), and sleep duration were derived.

RESULTS

Actor-partner interdependence model revealed that caregivers' greater alterations in arousal and reactivity were associated with their own longer SOL ( b = 15.59, p < .001) and their patients' longer sleep duration ( b = 0.61, p = .014), whereas patients' arousal and reactivity were associated with their caregivers' shorter SOL ( b = -8.47, p = .050). Patients' and caregivers' greater negative alterations in cognitions and mood were associated with patients' longer SOL ( b = 9.15, p = .014) and shorter sleep duration ( b = -0.41, p = .050), respectively. Caregivers' greater intrusion was related to their own shorter SOL ( b = -10.14, p = .004).

CONCLUSIONS

The four PTSS clusters, particularly arousal and reactivity and negative cognitions and mood, have distinct associations with sleep markers individually and dyadically in patients and caregivers affected by cancer. Investigations of psychosocial and biobehavioral pathways underlying these relations are warranted. Tailored trauma treatments and sleep interventions may improve the well-being of this population.

Emotional Support from Care Recipients, Caring Relationship Quality, and Caregiving Self-Efficacy among Family Caregivers of Older Adults

We analyzed 756 family caregivers (mean age = 62.3 years), investigating how emotional support from older care recipients was linked to caregivers' self-efficacy through caring relationship qualtiy. Results indicate a significant positive association between emotional support and caregivers' self-efficacy (r = 0.207, p < .01). Caring relationship quality positively correlated with emotional support (r = 0.292, p < .01) and caregivers' self-efficacy (r = 0.141, p < .01). Controlling for socialdemographic and care-related factors, relationship quality partially mediated the association between emotional support from care recipients and caregivers' self-efficacy. This suggests that interventions supporting caregivers' self-efficacy may benefit from considering both care recipients and dyadic relationships.

Supporting the support person: Oncologists' roles in reducing support people's uncertainty and facilitating psychological adjustment

OBJECTIVE

Support people of cancer patients are at significant risk for psychological distress. Additionally, cancer patients' well-being is reciprocally associated with support peoples' psychological well-being. Informed by Uncertainty in Illness Theory, this study tests whether support person psychological well-being is influenced by provider communication and uncertainty reduction.

METHODS

We tested a multiple mediation model to investigate how empathic communication facilitates psychological adjustment in support people of cancer patients and how this process is mediated by support peoples' illness uncertainty and caregiver burden. Support people of cancer patients (N = 121; including spouses, adult children, etc.) completed an online questionnaire about their perceptions of oncologists' empathy, uncertainty about the cancer patients' illness, perceived caregiving burden, and their psychological adjustment to diagnoses.

RESULTS

Path analysis revealed that (1) more perceived oncologist empathy was associated with less illness uncertainty, (2) more illness uncertainty was associated with worse psychological adjustment and more perceived caregiver burden, and (3) more burden was associated with worse adjustment (χ2 (2) = 1.19, p = 0.55; RMSEA < 0.01; CFI = 1.00; SRMR = 0.02).

CONCLUSIONS

Given the reciprocal nature of well-being between cancer patients and their support people, it is critical to understand and bolster support people's psychological well-being. Results demonstrated how empathic provider communication can support psychological well-being for support people of cancer patients. Additionally, this study offers theoretical contributions to understandings of illness uncertainty in caregiver populations.

Effectiveness of dyadic interventions among cancer dyads: An overview of systematic reviews and meta-analyses

AIMS AND OBJECTIVE

To summarize evidence from systematic reviews (SRs)/meta-analyses (MAs) regarding the impact of dyadic interventions delivered to both members of a cancer dyad, including a cancer patient and caregiver (e.g. family caregiver, intimate partner).

DESIGN

This overview of SRs was conducted in accordance with the preferred reporting items for overviews of reviews statement.

METHODS

A comprehensive search of multiple databases, including PubMed, Cochrane Library, Embase, CINAHL, Web of Science, China National Knowledge Infrastructure and Wan Fang. The methodological and reporting quality of SRs and MAs was assessed using the Assessing the Methodological Quality of Systematic Reviews 2. The quality of the included SRs/MAs was evaluated using the Grades of Recommendations, Assessment, Development and Evaluation approach.

RESULTS

Eighteen SRs/MAs undertook quantitative synthesis to assess the impact of dyadic interventions on cancer dyads. Both the credibility of the SRs/MAs and the evidence quality of the outcome measures were below satisfactory standards. Prior SRs/MAs revealed several limitations such as lack of pre-published protocols or research objectives, failure to report excluded studies and insufficient details on funding sources for individual studies.

CONCLUSIONS

Dyadic interventions may prove advantageous for the physical health and dyadic adjustment of cancer dyads. Nevertheless, the reported results of dyadic interventions on the psychological health of patient-caregiver dyads affected by cancer are inconsistent. Thus, rigorous and comprehensive studies are requisite to establish reliable evidence for conclusive determinations.

RELEVANCE TO CLINICAL PRACTICE

The findings of this overview can guide healthcare practitioners when considering the use of dyadic interventions for cancer dyads. Moreover, these findings have the potential to enhance the integration of these approaches into clinical practice.

Our paper presents an overview of systematic reviews, and therefore, such specific details may not be relevant to our study.

Using the Actor-Partner Interdependence Model to explore the psychological impact of COVID-19 on anxiety in dyads of patients with cancer and caregivers

BACKGROUND

Delineating the compound psychological effect of the pandemic on cancer care, and the interdependency across cancer patient-caregiver dyads have yet to be explored. This study examines the levels of psychological impact of COVID-19 on patient-caregiver dyads anxiety, and the interdependent associations between their COVID-19 and cancer concerns, and risk perceptions.

METHOD

There were 352 patients and caregivers (patient-caregiver dyads, N = 176) included in this study (43.2% spousal dyads). Generalized Anxiety Disorder-7 and questionnaires regarding risk perception, perceived confidence in healthcare system, COVID-19, and cancer-related concerns were administered. Actor-Partner Interdependence Model (APIM) analyses were used to determine the interdependent effects. Indirect effects were tested using mediation pathway analyses.

RESULTS

Patients reported significantly higher levels of risk perceptions and anxiety than their caregivers (p < 0.01). Anxiety rates (GAD-7 ≥ 10) were also significantly higher (26.7% vs 18.2%, p < 0.01). Dyads' anxiety, "general COVID-19 concerns," "cancer-related concerns," and risk perceptions were correlated (ps < 0.01). APIM showed only actor effects of general COVID-19 concerns, cancer-related COVID-19 concerns, and risk perceptions on anxiety (βs = 0.19-0.53, ps < 0.01). No partner effects were observed. Similar results were found in the composite APIM. Indirect effects of the patient/caregiver's variables on their partner's anxiety were observed in the mediation analyses.

CONCLUSION

Concerns about COVID-19 and cancer care could be indirectly associated in patient-caregiver dyads and need to be proactively addressed. As pandemic evolves into endemicity, engagement with patients and caregivers should strive to be sensitive to their differential needs and messages should be tailored to the informational needs of each.

Does gender moderate resiliency variables and posttraumatic stress symptoms in informal caregivers of neurocritical care patients? An exploratory study

We examined gender differences between resiliency factors (i.e. mindfulness, self-efficacy, coping, intimate care, and caregiver preparedness) and posttraumatic stress symptoms (PTSS) in informal caregivers of patients in the neuroscience intensive care unit (Neuro-ICU). Ninety-two informal caregivers were enrolled during patients' hospitalization and completed resiliency measures at baseline, and a PTSS measure at baseline, 3 and 6 months. We conducted five ANCOVAs to explore gender and resiliency on PTSS. No significant main effects of gender on PTSS were observed across time points. However, main effects were seen for resiliency on PTSS at baseline for informal caregivers with high (vs. low) mindfulness, coping, and self-efficacy. Gender moderated the association between mindfulness and PTSS (i.e. high mindfulness at baseline was associated with lower PTSS in males compared to females at 3 months) and intimate care and PTSS (high intimate care at baseline was associated with lower PTSS in males than females at 6 months; high intimate care at baseline for females was associated with lower PTSS at 6 months than females with low intimate care). Overall, we observed associations among informal caregivers' gender, resiliency, and PTSS, with males particularly benefitting from mindfulness and intimate care. These findings hold value for future inquiry into gender differences in this population with possible clinical implications.

Distinct dyadic quality of life profiles among patient-caregiver dyads with advanced lung cancer: a latent profile analysis

PURPOSE

This study aimed to identify the heterogeneity of dyadic quality of life (QoL) profiles, determine whether these profiles differ in terms of demographic and medical factors, neuroticism, resilience, and family functioning, and explore the combined effect of patient and caregiver neuroticism, resilience, and family functioning on dyadic QoL profiles.

METHODS

A cross-sectional study was conducted with 304 advanced lung cancer patient-caregiver dyads. Self-report questionnaires were administered to patient-caregiver dyads to assess demographic and medical characteristics, neuroticism, resilience, family functioning, and QoL.

RESULTS

The latent profile analysis identified four subgroups of dyadic QoL: patient-low-caregiver-high profile (38.82%), patient-high-caregiver-high profile (22.37%), patient-high-caregiver-low profile (19.74%), and patient-low-caregiver-low profile (19.08%). Additionally, when both patients and their caregivers had a high level of neuroticism or low level of resilience and low family functioning, compared with only member having them, there was a higher risk of poorer dyadic QoL.

CONCLUSIONS

Our study identified the four heterogeneities of dyadic QoL profiles among advanced lung cancer patient-caregiver dyads. Future dyadic interventions should consider the heterogeneity of dyadic QoL in this population and prioritize patient-caregiver dyads at risk of poor dyadic QoL. Furthermore, when high neuroticism, low resilience, or family functioning coexist between patients and their caregivers, both parties exhibit much lower dyadic QoL.

Underserved head-and-neck and lung cancer patient characteristics are associated with caregiver participation in a clinical trial

Background

Patient-caregiver relationships affect cancer outcomes, yet factors related to joint enrollment in cancer research trials are unclear. This work examined associations between cancer patients' sociodemographic and health factors and their caregivers' trial participation.

Methods

Baseline data were drawn from a parent trial testing psychosocial interventions delivered to medically underserved head-and-neck cancer (HNC) and lung cancer (LC) patients (N = 274) and caregivers (N = 210). Logistic regression evaluated whether patient characteristics were associated with participating alone versus with a caregiver(s) and type of caregiver.

Results

Many patients (65.0%) had a caregiver in the study, which was more common for married (OR = 2.05, p < .01) and retired patients (OR = 1.95, p < .05). Patients who indicated Hispanic (OR = 2.31, p < .05), Medicaid insurance (OR = 4.12, p < .001), monthly income <$4000 (OR = 3.04, p < .01), and smoked (OR = 2.87, p < .01) were more likely to enroll with a non-spouse/partner caregiver versus a spouse/partner. Participation was unrelated to distress.

Conclusions

Patient characteristics highlight caregiver relationships, informing trial design and recruitment for medically underserved cancer populations. Psychosocial interventions targeting underserved patients and their informal caregivers, those most in need of intervention support, should consider the inclusion of non-spousal cancer caregivers. Understanding how patient factors may be associated with caregiver involvement informs recruitment strategies and increases the utility of psychosocial interventions.

Dyadic Effects of Psychological Health on Quality of Life in Patients with Colorectal Cancer and Caregivers: A Systematic Review and Meta-Analysis

OBJECTIVES

This study aimed to review dyadic research on psychological health and health-related quality of life (HRQL) in patients with colorectal cancer (CRC) and caregivers and examine the pooled partner effects and actor effects based on the Actor-Partner Interdependence Model.

DATA SOURCES

A systematic review and meta-analysis were conducted. We registered our review protocol with PROSPERO (CRD42021258482). Six databases were searched until June 2021 using the following keywords: colorectal neoplasms, caregivers, depression, anxiety, stress, and quality of life. Two reviewers independently screened 1,597 studies that included both CRC patients and family caregivers. Meta-analyses were performed of the partner and actor effects of psychological health on HRQL in CRC.

CONCLUSION

Eighteen observational studies involving 2,757 patients with CRC and 2,601 caregivers were included. Regarding partner effects, the distress of patients with CRC affected their family caregivers' distress and burden. There were three types of actor effects among patients with CRC and family caregivers: 1) the social support of patients with CRC affects their level of distress; (2) the distress of patients with CRC affects their HRQL; and (3) caregivers' social support affects their level of distress. This study provides the first comprehensive overview of the dyadic relationships between psychological health and HRQL in patients with CRC and their caregivers.

IMPLICATIONS FOR NURSING PRACTICE

The development of dyadic interventions for improving psychological health is warranted to help both patients with CRC and their family caregivers live with improved HRQL and well-being.

Marital satisfaction, partner communication, and illness acceptance among couples coping with breast cancer: A dyadic approach

OBJECTIVE

Associations between marital satisfaction and illness acceptance are mediated by different factors. This study examines whether partner communication mediates relationships between marital satisfaction and illness acceptance among couples coping with breast cancer within a dyadic approach.

METHODS

One hundred and thirty-six couples were examined: 136 women with a diagnosis of breast cancer and their 136 spouses without a history of cancer. Questionnaires measuring marital satisfaction, partner communication, and illness acceptance were used. SEM analysis was applied to examine mediation effects.

RESULTS

For the patients, marital satisfaction was positively associated with supportive self-communication, supportive partner communication, and illness acceptance. For the spouses, marital satisfaction was positively correlated with supportive self-communication and supportive partner communication, yet, it was negatively correlated with deprecating communication of both self and partner. The associations between marital satisfaction and illness acceptance were mainly mediated by supportive communication (self and partner).

CONCLUSIONS

An examination of partner communication within a dyad is crucial for understanding relationships between marital satisfaction and illness acceptance in breast cancer patients. These relationships predominantly depend on the supportive communication of cognitive and emotional information between the spouses.

Family Caregiver Reports of Their Own and Patient Symptoms in Cancer Home Hospice Approaching End-of-Life

Context: Family caregivers assume the primary responsibility of assessing and managing hospice cancer patient symptoms while simultaneously managing their own wellbeing and symptoms. Objectives: Describe caregivers' assessment of hospice cancer patient and their own symptoms during the last 60 days of patient life, and assess the relationship between patient and caregiver symptoms over time. Methods: Caregiver symptom report of self and cancer home hospice patient symptom data were collected via telephone in the final 60 days of patient life. Descriptive data on symptom severity and prevalence were summarized. Exploratory Factor Analysis was used to group individual symptoms. Factors representing patient symptoms, caregiver symptoms, and caregiver outlook were analyzed using mixed-effects analysis to determine relationships between factors and change in relationship between factors over time. Results: Data from 61 patient-caregiver dyads are presented. At least 1 day of moderate-to-severe symptoms were reported in the majority of dyads. Significant auto-regressive associations were found, namely previous factor scores for an individual positively predicted the next factor scores for that individual. Previous caregiver report of patient symptoms was also positively associated with the next report of caregiver symptoms; previous caregiver report of their own symptoms were negatively associated with their next report of patient symptoms. Patient and caregiver symptoms and caregiver outlook worsened over time and the relationship between patient and caregiver symptoms strengthened closer to death. Conclusion: Our findings may guide hospice care team responses to caregiver and patient symptoms to promote individual level and unit level functioning.

Psychological Burden of Patients with Head and Neck Cancer Undergoing Radiotherapy and Their Family Caregivers: A Cross-Sectional Survey

Background

The consequences of Head and neck cancer (HNC) affect both the person who receives the diagnosis and their family caregivers (FCs).

Objective

To investigate the psychological status of patients and their FCs, and the burden of the FCs during radiotherapy.

Methods

This cross-sectional study was conducted with a questionnaire survey by convenience sampling method. Patients with HNC and their caregivers (both N = 85) from the radiotherapy department of our hospital were recruited between March 2021 and March 2022. The Hospital Anxiety and Depression Scale (HADS), the Chinese version of the Connor and Davidson Resilience Scale (CD-RISC), and the Zarit Burden Interview (ZBI) were used to assess the symptoms of anxiety and depression, psychological resilience, and the impact of care work, emotions and social lives of participants. Pearson's correlation analysis and a Mann-Whitney test were used to analyse the association between the HADS and the CD-RISC scores of the patients.

Results

About half of the patients (56.47%) and the caregivers (62.35%) have had anxiety. The average HADS-Anxiety scores, HADS-Depression scores, and CD-RISC scores of the patients with HNC were 7.4±1.9, 6.4±2.2, and 56.8±12.6. The "Strength" and "Resilience" scores of the patients were inversely related to their HADS anxiety scores (p < 0.05). The "Resilience" and "optimism" scores of them were inversely related to HADS depression scores (p < 0.05). The average ZBI score of the caregivers was 23.8±10.1; HADS anxiety scores and HADS depression scores of the caregivers were positively associated with total ZBI scores and individual burden scores (p < 0.05).

Conclusion

More than half of patients with HNC undergoing radiotherapy have anxiety, and about a third have depression. The anxiety and depression status of the FCs of patients with HNC undergoing radiotherapy is related to caregiver burden, deserving the attention of clinical medical staff.

A prospective study of psychological distress among patients with advanced cancer and their caregivers

BACKGROUND

Cancer can impact the psychological well-being of both patients and their informal caregivers. We investigated the joint trajectories of psychological distress among Singaporean advanced cancer patients-caregiver dyads. We also examined predictors of trajectory group membership.

METHODS

This study utilised data from 299 patients with advanced solid cancer and their caregivers over 33 months (12 times points). Group-based trajectory modelling was used to examine the joint trajectories of patient anxiety, patient depression, caregiver anxiety and caregiver depression scores using the Hospital Anxiety and Depression Scale.

RESULTS

Four joint trajectory groups were found: (1) Patient-caregiver low distress (27%), (2) patient-caregiver increasing distress (28.5%), (3) patient low- caregiver borderline distress (25%), (4) patient-caregiver high distress (19.5%). Dyads where the patient is below 50 years of age were more likely to be in Group 4. Dyads where caregiver-patient emotional closeness was low were more likely to be in Groups 2 or 4 where dyads reported increasing/high distress. Dyads that reported financial inadequacy were more likely to be in Groups 2, 3 and 4, while dyads with caregivers who were employed were more likely to be in group 3.

CONCLUSIONS

A substantial proportion of patients and caregivers reported anxiety and/or depression that lasted or increased throughout the study duration. We found significant heterogeneity in how dyads experienced psychological distress, suggesting that efforts should consider dyadic differences when providing psychological support. Particular focus should be placed on identifying dyads that are at risk and who require additional support.

Psychosocial Experiences, Challenges, and Recommendations for Care Delivery among Partners of Breast Cancer Survivors: A Qualitative Study

For women diagnosed with breast cancer, partners are consistently identified as the primary support person. Despite growing consensus about the psychosocial experience and unmet needs of cancer caregivers, limited evidence exists about strategies to offer partner-centered care across the cancer continuum. This study describes challenges endured by partners of breast cancer survivors (BCS), strategies implemented to manage these experiences, and recommendations for healthcare providers to inform targeted psychosocial care. Using convenience sampling, 22 partners of female BCS were recruited and completed semi-structured interviews. Conventional content analysis was used to code and synthesize findings. Participants described undergoing five experiences in their role as romantic partners: (a) assuming the role of caregiver, (b) becoming healthcare advocates for BCS, (c) connecting emotionally with the partner, (d) managing their own painful emotions, and (e) connecting with others for support. Experience-specific coping strategies and recommendations were identified. Romantic partners face multiple transitions across the cancer care continuum, which warrant investigation to sustain their well-being and active participation in illness management. Psychosocial interventions for this group will benefit from flexible implementation and attention to care delivery, mental health, and supportive/social needs.

Beliefs and interests in physical activity programs of cancer survivors and their romantic partners

PURPOSE

Physical activity is associated with improved health outcomes for cancer survivors and their romantic partners, yet it is unclear if joint exercise programs for survivor-partner dyads are acceptable. This study examined demographic, relationship, exercise, and cancer history correlates of survivors' and their romantic partners' couples-based exercise beliefs and their preferences for program designs.

METHODS

All participants (survivors n=209, partners n=155, couples n=143) completed an online survey. Correlations and linear regression analyses were used to examine correlates of participants' importance of and interest in couples-based exercise and their likelihood of joining a couples-based exercise program. Intraclass correlations estimated shared variance at the couple level.

RESULTS

Most participants believed that couples-based exercise was highly important (51.8%) and were interested in a couples-based exercise program (61.5%), but fewer survivors believed their partner would be interested or would likely join a couples-based program. Across all outcomes, partner support for exercise was most strongly associated with participants' couples-based exercise beliefs (r = 0.19-0.54, p<.05), and couples were significantly aligned in their beliefs (ρ=0.20-0.31, p<.01). Participants were interested in exercise programs involving exercising together (67.3%) as well as exercising separately while sharing activity data on an app or website (48.0%).

CONCLUSIONS

This novel understanding of couples-based exercise beliefs provides a strong foundation upon which future exercise programs may be designed for survivors and their romantic partners.

IMPACT FOR CANCER SURVIVORS

Survivors' adoption and maintenance of exercise may be enhanced by the inclusion of romantic partners in exercise programs, and partners' inclusion is appealing to couples.

Taking Care of Us© (TCU) study protocol: feasibility and acceptability of a dyadic intervention for couples living with heart failure

BACKGROUND

There are more than 1 million hospital admissions and 3 million emergency visits for heart failure in the USA annually. Although spouse/partners make substantial contributions to the management of heart failure and experience poor health and high levels of care strain, they are rarely the focus of heart failure interventions. This protocol describes a pilot randomized controlled trial that tests the feasibility, acceptability, and preliminary change in outcomes of a seven-session couple-based intervention called Taking Care of Us© (TCU). The TCU© intervention is grounded in the theory of dyadic illness management and was developed to promote collaborative illness management and better physical and mental health of adults with heart failure and their partners.

METHODS

A two-arm randomized controlled trial will be conducted. Eligible adults with heart failure and their co-residing spouse/partner will be recruited from a clinical site in the USA and community/social media outreach and randomized to either the TCU© intervention or to a control condition (SUPPORT©) that offers education around heart failure management. The target sample is 60 couples (30 per arm). TCU© couples will receive seven sessions over 2 months via Zoom; SUPPORT© couples will receive three sessions over 2 months via Zoom. All participants will complete self-report measures at baseline (T1), post-treatment (T2), and 3 months post-treatment (T3). Acceptability and feasibility of the intervention will be examined using both closed-ended and open-ended questions as well as enrollment, retention, completion, and satisfaction metrics. Preliminary exploration of change in outcomes of TCU© on dyadic health, dyadic appraisal, and collaborative management will also be conducted.

DISCUSSION

Theoretically driven, evidence-based dyadic interventions are needed to optimize the health of both members of the couple living with heart failure. Results from this study will provide important information about recruitment and retention and benefits and drawbacks of the TCU© program to directly inform any needed refinements of the program and decision to move to a main trial.

Patient-caregiver relationship in cancer fatigue and distress. A dyadic approach

It has been shown that a reciprocal relationship between cancer patients and their family caregivers positively decreases distress in both. In this context we tried to explore the role of relationship reciprocity in the dyad members’ symptoms of fatigue and distress (anxiety and depression). Specifically, we aimed to assess the implications of relationship reciprocity testing the link between the various measurements of patient Quality of Life (QoL) and caregiver burden and the other measures of fatigue, distress, and relationship reciprocity. Moreover we aimed to examine the inter-relatedness of patients’ and caregivers’ relationship reciprocity with their own as well as fatigue and distress of the dyads. A convenience sample of 545 adult cancer patients and their caregivers from 15 cancer centers were examined using a cross-sectional design. Participants were administered dyadic measures (fatigue, distress, relationship reciprocity) and individual measures (patients’ QoL and caregivers’ burden). Patients’ QoL and caregivers’ Burden were associated with fatigue, distress and relationship reciprocity. The Actor-Partner Interdependence Model (APIM) revealed that each person’s relationship reciprocity was associated with their own distress and fatigue (actor effects); only caregivers’ relationship reciprocity was associated with patients’ fatigue and distress (partner effects). These findings suggest that the implication of the caregiving relationship for fatigue symptoms in both - patients and caregivers - appears worth of investigation.

The Impact of Depression on Quality of Life in Caregivers of Cancer Patients: A Moderated Mediation Model of Spousal Relationship and Caring Burden

Family caregivers play an important role in managing and supporting cancer patients. Although depression in family caregivers is known to negatively affect caregiver health, the mechanism by which it affects caregivers is not clear. The purpose of this study was to explore the influence of depression on quality of life (QoL) in family caregivers of patients with cancer. Specifically, this study examined (1) whether caring burden mediates the relationship between depression and QoL, and (2) how this mediating effect varies depending on the caregiver's relationship with the patient. This study performed a secondary analysis on cross-sectional survey data. Ninety-three family caregivers of cancer patients were included in the study. Moderated mediation analyses were conducted using PROCESS macro with the regression bootstrapping method. The moderated mediation models and the indirect effect of caregiver depression on QoL through caring burden were significantly different depending on caregivers' relationships with patients (i.e., spousal or non-spousal). Specifically, the indirect effect of caregiver depression on QoL was greater for the patient's spouse than for other family caregivers. Healthcare providers should focus on identifying caregivers' depression and relationship with the patient and offer tailored support and intervention to mitigate the caring burden and improve the caregivers' QoL.

Relationship quality and psychophysiological distress for underserved breast cancer patients and their caregiver before treatment

OBJECTIVE

Breast cancer patients and caregivers experience biobehavioral reactivity (e.g., depression, anxiety, pain, fatigue) during breast cancer treatment which predicts cancer recurrence and mortality. High quality patient-caregiver relationships can mitigate this distress during treatment, but this association is unclear pre-treatment. Identifying early interventions that target high risk Appalachian patients could impact biobehavioral reactivity.

METHODS

We recruited 55 breast cancer patient-caregiver dyads to complete a self-report survey after diagnosis but before treatment. We used a series of Actor-Partner Interdependence Models to test the hypotheses that both patient and caregiver relationship quality would be linked to their own and their partners' biobehavioral reactivity.

RESULTS

Caregiver reported marital quality lower caregiver anxiety, patient anxiety, caregiver depression, patient depression, caregiver pain, and caregiver fatigue. Interestingly, patient-reported marital quality was linked with higher caregiver anxiety, higher patient anxiety, lower patient depression, and lower patient pain. Patients reported family quality was linked to lower patient and caregiver pain.

CONCLUSIONS

This study demonstrates that pre-treatment marital and family quality levels are directly related to psychophysiological measures in both the caregiver and the patient, though sometimes in unexpected directions. Additionally, our findings potentially reveal an opportunity to intervene at the time of diagnosis to improve relationship quality, impacting patient and caregiver psychophysiological outcomes.

Effectiveness and moderators of cancer patient-caregiver dyad interventions in improving psychological distress: A systematic review and meta-analysis

Objective

As patients and family caregivers are increasingly viewed as a dyadic whole, growing studies have emerged that identify ways to improve the two parties’ emotional distress. However, the specific effectiveness, quality, and optimal intervention details of these studies are unclear. Our objective is to synthesize the effectiveness of existing dyadic interventions for improving the psychological distress of cancer patient-caregiver dyads and identify potential moderators that influence intervention effectiveness.

Methods

PubMed, Cochrane Library, Web of Science, CINHAL, Embase, and Clinical Trials were searched to identify all randomized controlled trials from inception until June 2021. Two reviewers performed the process independently. The Cochrane Risk of Bias tool was used for quality assessment. We calculated effect sizes (Hedges’ adjusted g) by standard mean difference. Potential moderators influencing the intervention effects were explored.

Results

We included 28 articles, of which 12 were available for meta-analysis. In total, 4784 participants were included, who were primarily middle-aged (M ​= ​58 years old), with the highest proportion reporting a diagnosis of “mixed cancer” (30%). Patients’ anxiety (g ​= ​−0.31; 95% CI: ​−0.51 to −0.12; P ​= ​0.001; I² ​= ​17%) and cancer-related distress (g ​= ​−0.32; 95% CI: ​−0.46 to −0.18; P ​< ​0.0001; I² ​= ​0%) were statistically significantly improved from baseline to post-intervention. Interventionist, delivery type, duration, and frequency were potential moderators for psychosocial interventions on negative emotions.

Conclusions

Face-to-face, relatively shorter interventions led by psychologists in moderator analysis seem to have better performance. Cancer dyad-based interventions were efficacious in improving the emotional distress of both parties in the dyad, but the effect was more apparent in patients than in family caregivers. However, the long-term effects were modest for both groups.

Dyadic coping and its association with emotional functioning in couples confronted with advanced cancer: Results of the multicenter observational eQuiPe study

Objective

How patients and their partners cope with advanced cancer as a couple, may impact their emotional functioning (EF). The aim of this study was to assess dyadic coping (DC) of couples confronted with advanced cancer and its association with EF.

Methods

Actor‐partner interdependence models were used to analyze baseline data of 566 couples facing advanced cancer participating in an observational study on quality of care and life. Measures included the DC Inventory and the European Organization for Research and Treatment of Cancer quality of life questionnaire (EOQLQ‐C30).

Results

Negative DC (mean 86–88) was most often used and common DC (both mean 66) was least often used. We found small to moderate interdependence (r = 0.27−0.56) between patients' and partners' DC perceptions. Compared to partners, patients were more satisfied with their DC (p < 0.001). Partners' satisfaction with DC was positively associated with their own (B = 0.40, p < 0.001) and patients' (B = 0.23, p = 0.04) EF. We found positive actor (patients B = 0.37 B = 0.13, p = 0.04) and partner (both B = 0.17, p < 0.05) associations for negative DC in patients and partners. Partners' supportive DC was negatively associated with patients (B = −0.31, p = 0.03) and partners' EF (B = −0.34, p = 0.003).

Conclusions

This study highlight the importance of DC (especially from the partners' perspective) for EF in advanced cancer but also identifies differences in the experience of patients and their partners. Future research is needed to understand the mechanisms of such relations and the common and unique support options that may facilitate adjustment in patients with advanced cancer and their partners.

Dyadic Interdependence in Non-spousal Caregiving Dyads’ Wellbeing: A Systematic Review

Caregiving dyads (i.e., an informal caregiver and a care recipient) work as an interdependent emotional system, whereby it is assumed that what happens to one member of the dyad essentially happens to the other. For example, both members of the dyad are involved in care giving and care receiving experiences and therefore major life events, such as a serious illness affect the dyad and not only the individual. Consequently, informal caregiving may be considered an example of dyadic interdependence, which is “the process by which interacting people influence one another’s experience.” This systematic review aimed to synthesize studies of dyadic interdependence, specifically in non-spousal caregiving dyads (e.g., adult children—parents, siblings, other relatives, or friends). Electronic databases (PsycINFO, Pubmed, and CINAHL) were systematically searched for dyadic studies reporting on interdependence in the emotional and relational wellbeing of non-spousal caregiving dyads. A total of 239 full-text studies were reviewed, of which 14 quantitative and qualitative studies met the inclusion criteria with a majority of dyads consisting of adult daughters caring for their older mothers. A narrative synthesis suggested mutual influences between non-spousal caregiving dyad members based on: (1) associations between intrapersonal (e.g., psychological functioning) and interpersonal (e.g., relationship processes) variables and emotional and relational wellbeing of the dyad; (2) associations between care context variables (e.g., socio-demographics and care tasks) and emotional and relational wellbeing of the dyad; and (3) patterns of covariation between caregivers’ and care recipients’ wellbeing. Evidence supporting dyadic interdependence among non-spousal caregiving dyads shed light on the ways dyad members influence each other’s wellbeing while providing and receiving care (e.g., via the exchange of support). Future studies investigating mutual influences in dyads, should differentiate subsamples of caregivers based on relationship type, and adopt dyadic and longitudinal designs.

Family Caregiver Preparedness: Developing an Educational Intervention for Symptom Management

BACKGROUND

Family caregivers provide complex care for patients with cancer, including management of multiple symptoms associated with the disease and its treatment.

OBJECTIVES

The objective of this pilot project was to develop and conduct feasibility testing of a family caregiver educational intervention for symptom management.

METHODS

The intervention was conducted with 23 family caregivers of patients with lung or gynecologic cancer to evaluate feasibility testing and assessment of caregiver preparedness, quality of life, and psychological distress at baseline and three and seven weeks postintervention.

FINDINGS

Family caregivers were very interested in education related to their role in symptom management, with management of constipation, dyspnea, and diarrhea as the highest priorities. The intervention was feasible and valuable in assisting family caregivers in assessing symptoms and making decisions regarding treatment choices.

Active Engagement, Protective Buffering, and Depressive Symptoms in Young-Midlife Couples Surviving Cancer: The Roles of Age and Sex

OBJECTIVE

Cancer researchers have found midlife couples to have poorer outcomes compared to older couples due to the off-time nature of the illness for them. It is unknown if young couples (aged 18-39), who are under-represented in cancer studies and overlooked for supportive programs, are at further risk. This study explored the moderating roles of survivor age and sex on the associations between active engagement and protective buffering and depressive symptoms in couples surviving cancer.

METHODS

The exploratory study comprised 49 couples (aged 27-58) 1-3 years post-diagnosis. Multilevel modeling was used to explore the moderating roles of survivor age and sex, controlling for interdependent data.

RESULTS

Approximately, 37% of survivors and 27% of partners met clinical criteria for further assessment of depression, with 50% of couples having at least one member meeting the criteria. Survivors and their partners did not significantly differ on depressive symptoms, active engagement, or protective buffering. Male survivors reported significantly higher levels of active engagement by their partners than female survivors and female survivors reported significantly higher levels of protective buffering by their partners than male survivors. We found some evidence to suggest that survivor age and sex may play moderating roles between active engagement and protective buffering and depressive symptoms. Older partners and female survivors appeared to experience more positive effects from engaging in positive dyadic behaviors than younger partners and male survivors.

CONCLUSION

Findings not only confirm the important role of dyadic behaviors for couples surviving cancer together, but also the important roles of survivor age and sex may play in whether such behaviors are associated with lower levels of depressive symptoms. Future research that examines these complex associations over time and across the adult life span in diverse populations is needed.

Financial distress and its associated burden in couples coping with an advanced cancer

PURPOSE

In efforts to understand financial distress (FD) associated with advanced cancer care from the perspective of both patients with incurable disease and their spousal caregivers, we assessed FD in both members of the couple, identified symptom and quality of life (QOL) correlates, and examined the potential role of illness communication.

METHODS

Patients undergoing treatment for stage III/IV lung cancer or a grade III/IV primary brain tumor and their spousal caregivers (n = 76 dyads) completed measures of somatic and affective symptoms including FD, physical and mental QOL, and ease of engaging in illness communication. Patients and caregivers additionally rated their perception of each other's symptoms, including FD.

RESULTS

FD was endorsed by both patients (any FD 62.7%; high FD 24%) and spousal caregivers (any FD 64.7%; high FD 32.3%). Self-reported FD was significantly correlated (partial r = .52, p < .001) within couples. FD was associated with greater symptoms of anxiety (r = .29, p = .01; r = .31, p = .01), depression (r = 29, p = 01; r = .39, p = .001), and poorer physical QOL(r =  - .25, p = .03; r =  - .25, p = .001) for patients and caregivers, respectively. For patients, FD was additionally associated with poorer mental QOL(r =  - .44, p < .001). Caregivers accurately perceived patient FD, yet patients tended to underreport their caregiver's FD by almost an entire point (t = 2.8, p = .007). A 3-way interaction (FD X role X illness communication) revealed (b = .40, p = .041) that illness communication moderated the association between FD and physical QOL for spouses so that spouses who reported less ease of illness communication demonstrated a stronger association between financial distress and physical QOL (b =  - 2.08, p < .001) than those reporting greater ease of engaging in illness communication (b = .49, p = .508).

CONCLUSION

In the advanced cancer setting, FD is prevalent in both patients and their spousal caregivers and associated with psychological distress and poor physical QOL. Results suggest that optimal FD assessment should include patients and spouses, and spouse's ease of engaging with illness communication may be a potential target for future intervention studies.

Feasibility, usability, and acceptability of personalized web-based assessment of social network and daily social support interactions over time

Purpose

The purpose of this study was to test the feasibility, usability, and acceptability of implementing a web-based method for collecting social network and longitudinal daily interaction data from cancer survivors and their caregivers.

Methods

Young adult and sexual/gender minority cancer survivors and their informal caregivers were recruited as dyads. Feasibility data, including enrollment and retention, were captured. Individual social network data were collected at baseline and used to individualize daily electronically delivered surveys assessing characteristics of daily social support-related interactions with identified network members for 14 days. Follow-up questionnaires assessing usability and exit interviews assessing acceptability were completed at the end of the 2-week study period.

Results

Fourteen survivor-caregiver dyads (28 individual participants) were enrolled and completed all baseline and final measures. Participants completed 85.2% of daily diary reports and reported excellent usability ratings. Acceptability was also high. In qualitative interviews, participants reported enjoying the daily reflection on social support facilitated by our methods.

Conclusions

Our method has been shown to be highly feasible, usable, and acceptable.

Implications for Cancer Survivors

Developing better data collection tools can lead to better understanding of the social support cancer survivors and their caregivers receive, and how the social network structure facilitates or creates barriers to accessing this support.

More often than not, we're in sync: patient and caregiver well-being over time in stem cell transplantation

Background

Hematopoietic stem cell transplantation (HSCT) is an aggressive medical procedure which significantly impacts the shared emotional well-being of patients and family caregivers (FC). Prior work has highlighted the significant overlap in well-being among patients and FCs; however, how this interdependence may change over the course of HSCT has received less attention.

Methods

We conducted secondary analyses of a supportive intervention delivered to 154 FCs of HSCT patients and examined relationships at baseline, 6 weeks, 3 and 6 months post-HSCT. Actor Partner Interdependence Modeling examined patient quality of life (QOL) and FC anxiety/depression.

Results

The data did not fit a multigroup approach limiting our ability to test intervention effects; however, bivariate analyses indicated FC depression significantly correlated to patient QOL at baseline (r = − .32), 6 weeks (r = − .22) and 6 months post-HSCT (r = − .34; p’s < .05); whereas FC anxiety was only correlated with patient QOL at the first two timepoints (p’s < .05). There was an unexpected, partner effect such that worse patient QOL at 6-weeks significantly related to lower FC depression at 3-months (B = .193; p = .026) and changed direction with patient QOL at 3-months being related to more FC depression at 6-months (B = − .187; p = .001).

Conclusions

These findings highlight the significant, yet nuanced, interdependence of patient QOL and FC well-being during HSCT. Specifically, greater interdependence was observed between patient QOL and FC depression compared to FC anxiety, suggesting potential treatment targets for patients and their families.

Factors associated with and risk factors for depression in cancer patients - A systematic literature review

Objective

The prevalence of depression in oncological patients is 3, 4-fold compared to the general population. However, the specific risk factors for these prevalence rates are not fully understood.

Methods

A systematic literature review was conducted in nine electronic databases between 2005 and 2020. The quality of the eligible studies was appraised by two persons using the adapted 11-items Downs and Black checklist.

Results

Among 2010 potentially relevant articles, 40 studies were eligible, with 27 studies of high quality and 13 studies of moderate quality. A total of 156 factors associated with depression were identified which were clustered into somatic, psychological, social and sociodemographic factors. Pre-existing depression and personality factors were the most consistent associated factors with depression in cancer patients, while for most somatic and treatment-related factors only modest associations were found.

Conclusions

Grouped as bio-psycho-social associated factors, somatic factors showed a modest influence, whereas social relationship (support) and previous depression are unequivocally significantly associated with depression.

Caring experiences of family caregivers of patients with pancreatic cancer: an integrative literature review

PURPOSE

This review summarizes and synthesizes the available empirical literature on the experiences concerned with the problems and challenges faced by caregivers of patients with pancreatic cancer.

METHODS

An integrative review method was used, and a literature search was conducted using five databases. We searched the terms "pancreatic cancer," "caregiver," and "experience," and used the Boolean operators OR and AND to combine them. The Joanna Briggs Institute critical appraisal tools were used to assess the quality of the included studies.

RESULTS

Four qualitative studies, one mixed method, and three quantitative studies met the selection criteria and were included in the review. Informal family caregivers of patients with pancreatic cancer experienced multifaceted roles, lack of information, difficulties in maintaining emotional well-being, and positive coping. The factors associated with their caring experience included the caregivers' demographics, patients' psychological status, and clinical characteristics.

CONCLUSION

Caregivers of patients with pancreatic cancer have various experiences while providing care. Health care providers should offer opportunities for caregivers to recognize their feelings, provide sufficient information and psychological support, and foster coping strategies to maintain the physical and psychosocial well-being of caregivers.

Psychological and behavioral moderators of physical health among caregivers and non-caregivers

The current study sought to evaluate whether psychological and/or behavioral health moderate the relationship between caregiving and physical health.

MATERIALS AND METHODS

Using data from the Behavioral Risk Factor Surveillance System (BRFSS) survey (2017-2018), separate composite scores were created for psychological and behavioral health. Self-reported physical health was the primary outcome. The sample was 1,387 non-caregivers and 266 caregivers.

RESULTS

The psychological, behavioral, and self-reported physical health did not significantly differ between caregivers and non-caregivers, but psychological and behavioral health were shown to differentially affect self-reported health outcomes among caregivers, compared to non-caregivers. Caregivers with worse psychological health had higher odds of experiencing poor physical health versus non-caregivers, while caregivers with better behavioral health had lower odds of having better general health versus non-caregivers.

DISCUSSION

These data extend our understanding on how to consider the impact of psychological and behavioral health as a caregiver and opportunities to develop targeted interventions.

Experiences of Family Caregivers of People with Dementia during the COVID-19 Pandemic

Although behavioral and psychological symptoms are burdensome for people with dementia and their caregivers, perceptions of family caregivers regarding management of these symptoms are unclear. This study explored the experiences of family caregivers regarding behavioral and psychological symptoms experienced by relatives with dementia, management of these symptoms, and changes in their experiences during the COVID-19 pandemic. A qualitative, exploratory approach using constant comparative methods was used; 21 family caregivers were interviewed virtually. The following 10 major themes emerged: (1) Emotional and psychological experiences of caregiver, (2) emotional, psychological, and behavioral responses of person with dementia, (3) cognition of person with dementia, (4) loss, (5) concerns for the future, (6) reliance, (7) learning to caregive, (8) rewarding aspects of caregiving, (9) caregiver perspectives, and (10) care strategies. Caregivers described many challenges to care before and during the pandemic. Acceptable and effective care strategies are needed to promote the well-being of families living with dementia.

Patient activation and treatment decision-making in the context of cancer: examining the contribution of informal caregivers' involvement

PURPOSE

The present work investigated the relationship between patient activation, treatment decision-making, and adherence to the prescribed treatment regimen. Given the role of informal caregivers in patient-reported outcomes, it was additionally assessed whether caregiver involvement acted as a moderator of this relationship.

METHODS

Survey data collected from 504 cancer survivors were utilized. Structural equation modeling (SEM) controlling for covariates was used to examine the relationship between patient activation measure (PAM), caregiver involvement, and the identified outcomes. Moderator analysis was conducted using multiple group SEM.

RESULTS

Patient activation was significantly associated with treatment planning being reflective of survivors' goals and values (p < 0.001); adherence to treatment (p = 0.011); and satisfaction (p < 0.001). Caregiver's involvement significantly moderated the association between activation and adherence to treatment.

CONCLUSIONS

Patient activation was positively associated with all three selected outcomes. However, for cancer survivors reporting low rates of caregiver's involvement, patient activation was not associated with treatment adherence. Research is needed to test and deliver self-management interventions inclusive of informal caregivers.

IMPLICATIONS FOR CANCER SURVIVORS

Findings supported the need not only to monitor and sustain patient activation across the cancer continuum, but also to assume a dyadic perspective when designing self-management interventions in cancer survivorship.

The Dyadic Cancer Outcomes Framework: A general framework of the effects of cancer on patients and informal caregivers

It is widely acknowledged that cancer affects not only patients but also their friends and family members who provide informal, and typically unpaid, care. Given the dual impact that cancer often has on patients and their informal caregivers (i.e., family members, partners, or friends), an expanded dyadic framework that encompasses a range of health and psychosocial outcomes and includes primary caregivers with a range of relationships to the patients is critically needed. Moreover, an emphasis on the role of social and contextual factors may help the framework resonate with a broader range of patient-caregiver relationships and allow for the development of more effective dyadic interventions. This article describes the development of the Dyadic Cancer Outcomes Framework, which was created to guide future research and intervention development. Using an iterative process, we conducted a conceptual review of currently used dyadic and/or caregiving models and frameworks and developed our own novel dyadic framework. Our novel Dyadic Cancer Outcomes Framework highlights individual- and dyad-level predictors and outcomes, as well as incorporating the disease trajectory and the social context. This framework can be used in conjunction with statistical approaches including the Actor Partner Interdependence Model to evaluate outcomes for different kinds of partner-caregiver dyads. This flexible framework can be used to guide intervention development and evaluation for cancer patients and their primary caregivers, with the ultimate goal of improving health, psychosocial, and relationship outcomes for both patients and caregivers. Future research will provide valuable information about the framework's effectiveness for this purpose.

Health and resource burden of a cancer diagnosis on the caregiver: an analysis of administrative claims data

PURPOSE

Cancer diagnosis is known to affect the family; however, administrative claims data are not commonly used to evaluate the broader impact of cancer diagnosis. This study was designed to evaluate the feasibility of using claims data to explore the impact of cancer diagnosis on the caregiver.

METHODS

IBM Marketscan data were used to identify eligible cancer patients, who were required to have a second adult over the age of 18 (defined as "caregiver" for this study) covered by the same the healthcare policy. Eligible control pairs included any two adults in the same policy with no evidence of cancer; for each pair one adult was randomly assigned to be the "patient control" while their partner was assigned as "caregiver control". Probabilistic stratified sampling was used select control pairs for analysis by matching the relative frequencies within sex and age group strata to those of patient/caregiver pairs. Eligible control pairs were probabilistically sampled without replacement until the stratum with at least 0.5 % relative frequency had been completely sampled. Caregiver and caregiver control healthcare resource utilization (HCRU), new diagnoses, and healthcare costs were compared during the 12-month post-diagnosis period. Subgroup analyses were conducted by cancer subtypes (breast, colorectal, lung, gastric, sarcoma) and by sex of the patient and caregiver.

RESULTS

A total of 62,893 patient/caregiver pairs and 449,177 control pairs were included. Overall, caregivers used slightly fewer healthcare resources and expended less costs during the 12-month period after the cancer diagnosis than controls (physician visits; 85.8 % vs. 95.7 %; hospitalizations 5.4 % vs. 7.0 %; emergency room visits 15.7 % versus 16.2 %, all p ≤ 0.001). This finding was consistent in all subgroup analyses. New diagnoses were lower in the caregiver cohort, except for mental disorders, which were higher than controls (14.3 % vs. 9.9 %, p < 0.0001). Psychotherapeutic/antidepressant utilization occurred among 21.0 % of caregivers versus 17.2 % of caregiver controls during this period.

CONCLUSIONS

It is feasible to use administrative claims data to evaluate the impact of a cancer diagnosis on the caregiver to evaluate outcomes such as HCRU, diagnoses and costs. These findings raise hypotheses about deferment of health care and increased mental distress during the caregiving period.

Challenges experienced and resources identified by young to midlife couples 1-3 years post-cancer diagnosis

OBJECTIVE

The purpose of this study was to explore what young to midlife couples viewed as their strengths as a couple and the greatest challenges in their experience with cancer 1-3 years post-diagnosis.

METHODS

We used qualitative content analysis to extract common themes from open-ended questions from 42 cancer survivors and their partners (aged 27-58). Patterns of themes by age and gender of the survivor were also explored.

RESULTS

Couples described both positive and negative impacts of the cancer experience: (1) strengthened the relationship, bringing couples closer together; (2) brought emotional strain to many areas of life, especially for partners; (3) created positive changes in lifestyle and new priorities for the couple; (4) created strain in the couple's relationship and intimacy; and (5) altered the role of family in supporting the couple. Couples also described four key strengths in dealing with the cancer experience: (1) drawing strength from shared love and mutuality; (2) communicating openly, even about the difficult stuff; (3) working together as a team to support each other; and (4) drawing strength from shared values and goals. Couples reported unmet needs related to the emotional and relational strain of the cancer experience, managing longer term survivor symptoms, fertility and physical intimacy, and lack of support or attention to the partner who often assumed the role of care partner.

CONCLUSIONS

Themes are discussed in light of current dyadic concepts and importance of couple-based interventions.

The Psychosocial Impact of Spouse-Caregiver Chronic Health Conditions and Personal History of Cancer on Well-being in Patients With Advanced Cancer and Their Caregivers

CONTEXT

Caregiving during advanced cancer presents many physical and psychological challenges, especially for caregivers who are coping with their own history of cancer or their own chronic health conditions. There is growing recognition that caregiver health and patient health are interdependent.

OBJECTIVES

The objective of this study was to use quantitative and interview data to examine and explore the impact of a caregiver's personal cancer history and chronic health conditions on the psychosocial well-being of both the caregiver and patient.

METHODS

This was a secondary analysis of data from 88 patients with advanced lung/gastrointestinal cancer and their spouse-caregivers. Participants self-reported subjective health, chronic health conditions (including cancer), anxiety and depression symptoms, and social support and social stress. Caregivers self-reported caregiving burden and preparedness for caregiving. Caregivers also completed semistructured interviews.

RESULTS

Participants were mostly white, non-Hispanic, and in their mid-60s. Caregivers reported 1.40 (SD = 1.14) chronic conditions on average; 11 reported a personal history of cancer ("survivor-caregivers"). The number of caregiver chronic health conditions was positively associated with patient depression symptoms. Patients of survivor-caregivers also reported more depression symptoms than patients of caregivers without cancer (t(85) = -2.35, P = 0.021). Survivor-caregivers reported higher preparedness for caregiving than caregivers without cancer (t(85) = -2.48, P = 0.015). Interview data enriched quantitative findings and identified factors that may drive patient depression, including emotions such as resentment or guilt. Experiencing cancer personally may provide caregivers unique insight into the patient experience.

CONCLUSION

Providers should be aware of caregiver chronic conditions and cancer history, given the potential negative effects on patient psychosocial well-being.

Post-traumatic stress symptoms in long-term disease-free cancer survivors and their family caregivers

Background

The experience of cancer is highly stressful and potentially traumatic. We assessed the presence of Post‐Traumatic Stress Symptoms (PTSS) in long‐term cancer survivors and their caregivers, while examining the association between PTSS and clinical, demographic and psychological variables in the long term.

Methods

In this cross‐sectional study 212 survivor‐family caregiver dyads completed measures of post‐traumatic stress symptoms (PTSS) (Impact of Event Scale), depression and anxiety (Hospital Anxiety Depression Scale). Coping strategies, fatigue, cognitive decline, stressful life events and psychopathological history were also assessed among survivors. Data were analyzed using mixed models, accounting both for individual and dyadic effects.

Results

Cancer survivors and their caregivers were assessed after a mean of 6 years after treatment. Twenty per cent of survivors and 35.5% of caregivers had possible posttraumatic stress disorder (PTSD), while 23 patients (11.0%) and 33 caregivers (15.6%) had probable PTSD. Among cancer patients, the severity of post‐traumatic symptoms was associated with an anxious coping style, previous psychopathology and depression (p < 0.001), whereas among caregivers it was associated with depression and having a closer relationship with patients (p < 0.001). Patients’ depression was associated with caregivers’ intrusion symptoms.

Conclusions

High levels of cancer‐related PTSS were still present several years after treatment in both survivors and caregivers. Psychopathology may derive from complex interactions among coping, previous disorders and between‐person dynamics.

eTRIO trial: study protocol of a randomised controlled trial of online education modules to facilitate effective family caregiver involvement in oncology

OBJECTIVE

Informal family caregivers play a crucial role in cancer care. Effective caregiver involvement in cancer care can improve both patient and caregiver outcomes. Despite this, interventions improving the caregiver involvement are sparse. This protocol describes a randomised controlled trial evaluating the combined effectiveness of novel online caregiver communication education modules for: (1) oncology clinicians (eTRIO) and (2) patients with cancer and caregivers (eTRIO-pc).

METHODS AND ANALYSIS

Thirty medical/radiation/surgical oncology or haematology doctors and nurses will be randomly allocated to either intervention (eTRIO) or control (an Australian State Government Health website on caregivers) education conditions. Following completion of education, each clinician will recruit nine patient-caregiver pairs, who will be allocated to the same condition as their recruiting clinician. Eligibility includes any new adult patient diagnosed with any type/stage cancer attending consultations with a caregiver. Approximately 270 patient-caregiver pairs will be recruited. The primary outcome is caregiver self-efficacy in triadic (clinician-patient-caregiver) communication. Patient and clinician self-efficacy in triadic communication are secondary outcomes. Additional secondary outcomes for clinicians include preferences for caregiver involvement, perceived module usability/acceptability, analysis of module use, satisfaction with the module, knowledge of strategies and feedback interviews. Secondary outcomes for caregivers and patients include preferences for caregiver involvement, satisfaction with clinician communication, distress, quality of life, healthcare expenditure, perceived module usability/acceptability and analysis of module use. A subset of patients and caregivers will complete feedback interviews. Secondary outcomes for caregivers include preparedness for caregiving, patient-caregiver communication and caring experience. Assessments will be conducted at baseline, and 1 week, 12 weeks and 26 weeks post-intervention.

ETHICS AND DISSEMINATION

Ethical approval has been received by the Sydney Local Health District Human Research Ethics Committee (REGIS project ID number: 2019/PID09787), with site-specific approval from each recruitment site. Protocol V.7 (dated 1 September 2020) is currently approved and reported in this manuscript. Findings will be disseminated via presentations and peer-reviewed publications. Engagement with clinicians, media, government, consumers and peak cancer groups will facilitate widespread dissemination and long-term availability of the educational modules.

Dyadic effects of family-functioning and resilience on quality of life in advanced lung cancer patients and caregivers: An actor-partner interdependence mediation model

PURPOSE

Lung cancer as a stressful event profoundly impacts the entire family, especially patients and their family caregivers. This study uses a dyadic analysis approach to explore the dyadic effects of family functioning on the quality of life (QoL), and whether resilience acts as a mediator in advanced lung cancer patient-caregiver dyads.

METHODS

This was a cross-sectional study, and 287 dyads of advanced lung cancer patients and their caregivers were enrolled. Family-functioning, resilience, and QoL were assessed by the General Functioning subscale of the Family Assessment Device (FAD), the 10-item Connor-Davidson Resilience Scale, and the Short Form-8 (SF-8) Health Survey, respectively. Data were analyzed using the actor-partner interdependence mediation model.

RESULTS

This study found that, for patients and caregivers, resilience mediates the actor effects of family-functioning on QoL. That is, family-functioning was positively related to their resilience, which improved QoL. Another important finding is that caregivers' family-functioning had significant indirect effects on patients' QoL through their resilience.

CONCLUSIONS

Positive family functioning perceived by patients and caregivers can improve their QoL by developing their own resilience. Furthermore, family-functioning perceived by caregivers can also improve patients' QoL through their resilience. Medical staff should identify vulnerable patients and caregivers with poorer family-functioning and resilience, and make focused intervention to improve the QoL of both lung cancer patients and their family caregivers.

Symptom distress and quality of life among Black Americans with cancer and their family caregivers

OBJECTIVE

Black Americans are disproportionately affected by cancer and chronic diseases. Black patients with cancer and their family caregivers may concurrently experience symptoms that influence their wellbeing. This study investigates the influence of mental and physical symptom distress on quality of life (QOL) among Black Americans with cancer and their family caregivers from a dyadic perspective.

METHODS

One hundred and fifty-one dyads comprised of a Black American with breast, colorectal, lung or prostate cancer and a Black family caregiver were included in this secondary analysis of pooled baseline data from three studies. Self-reports of problems managing 13 symptoms were used to measure mental and physical symptom distress. Descriptive statistics and the actor-partner interdependence model were used to examine symptom prevalence and the influence of each person's symptom distress on their own and each other's QOL.

RESULTS

Fatigue, sleep problems, pain and mental distress were prevalent. Patients and caregivers reported similar levels of mental distress; however, patients reported higher physical distress. Increased patient mental distress was associated with decreased patient QOL (overall, emotional, social, functional). Increased patient physical distress was associated with decreased patient QOL (overall, physical, emotional, functional) and decreased caregiver emotional wellbeing. Increased caregiver mental distress was associated with decreased caregiver QOL (overall, emotional, social, functional) and decreased patient overall QOL. Increased caregiver physical distress was associated with decreased caregiver QOL (overall, physical, functional), decreased patient emotional wellbeing, and better patient social wellbeing.

CONCLUSIONS

Supporting symptom management in Black patient/caregiver dyads may improve their QOL.

Feasibility and Efficacy of a Resiliency Intervention for the Prevention of Chronic Emotional Distress Among Survivor-Caregiver Dyads Admitted to the Neuroscience Intensive Care Unit: A Randomized Clinical Trial

IMPORTANCE

To our knowledge, there are no evidence-based interventions to prevent chronic emotional distress (ie, depression, anxiety, and posttraumatic stress [PTS]) in critical care survivors and their informal caregivers.

OBJECTIVE

To determine the feasibility and preliminary effect of the novel dyadic resiliency intervention Recovering Together (RT) on reducing symptoms of depression, anxiety, and PTS among hospitalized patients and their informal caregivers.

DESIGN, SETTING, AND PARTICIPANTS

This single-blind, pilot randomized clinical trial of RT vs an educational control was conducted among 58 dyads in which either the survivor or caregiver endorsed clinically significant symptoms of depression, anxiety, or PTS. The study was conducted in the neuroscience intensive care unit at Massachusetts General Hospital. Data were collected from September 2019 to March 2020.

INTERVENTIONS

Both RT and control programs had 6 sessions (2 at bedside and 4 via live video after discharge), and both survivor and caregiver participated together.

MAIN OUTCOMES AND MEASURES

The primary outcomes were feasibility of recruitment and intervention delivery, credibility, and satisfaction. The secondary outcomes included depression and anxiety (measured by the Hospital Depression and Anxiety Scale), PTS (measured by the PTSD Checklist-Civilian Version), and intervention targets (ie, mindfulness, measured by the Cognitive and Affective Mindfulness Scale-Revised; coping, measured by the Measure of Current Status-Part A; and dyadic interpersonal interactions, measured by the Dyadic Relationship Scale). Main outcomes and targets were assessed at baseline, 6 weeks, and 12 weeks.

RESULTS

The 58 dyads were randomized to RT (29 dyads [50.0%]; survivors: mean [SD] age, 49.3 [16.7] years; 9 [31.0%] women; caregivers: mean [SD] age, 52.4 [14.3] years; 22 [75.9%] women) or control (29 dyads [50.0%]; survivors: mean [SD] age, 50.3 [16.4] years; 12 [41.3%] women; caregivers, mean [SD] age, 52.1 [14.9], 17 [58.6%] women). Feasibility (recruitment [76%], randomization [100%], and data collection [83%-100%]), adherence (86%), fidelity (100%; κ = 0.98), satisfaction (RT: 57 of 58 [98%] with scores >6; control: 58 of 58 [100%] with scores >6), credibility (RT: 47 of 58 [81%] with scores >6; control: 46 of 58 [80%] with scores >6), and expectancy (RT: 49 of 58 [85%] with scores >13.5; 51 of 58 [87%] with scores >13.5) exceeded benchmarks set a priori. Participation in RT was associated with statistically and clinically significant improvement between baseline and postintervention in symptoms of depression (among survivors: -4.0 vs -0.6; difference, -3.4; 95% CI, -5.6 to -1.3; P = .002; among caregivers: -3.8 vs 0.6; difference, -4.5; 95% CI, -6.7 to -2.3; P < .001), anxiety (among survivors: -6.0 vs 0.3; difference, -6.3; 95% CI, -8.8 to -3.8; P < .001; among caregivers: -5.0 vs -0.9; difference, -4.1; 95% CI, -6.7 to -1.5, P = .002), and PTS (among survivors: -11.3 vs 1.0; difference, -12.3; 95% CI, -18.1 to -6.5, P < .001; among caregivers, -11.4 vs 5.0; difference, -16.4, 95% CI, -21.8 to -10.9; P < .001). Improvements sustained through the 12-week follow-up visit. We also observed RT-dependent improvement in dyadic interpersonal interactions for survivors (0.2 vs -0.2; difference, 0.4; 95% CI, 0.0 to 0.8; P = .04).

CONCLUSIONS AND RELEVANCE

In this pilot randomized clinical trial, RT was feasible and potentially efficacious in preventing chronic emotional distress in dyads of survivors of the neuroscience intensive care unit and their informal caregivers.
