The mutual impact and moderating factors of quality of life between advanced cancer patients and their family caregivers

Cancer patient and caregiver communication about economic concerns and the effect on patient and caregiver partners' perceptions of family functioning

PURPOSE

Financial strain and stressful life events can constrain open communication within families. A cancer diagnosis can bring heightened emotional stress and financial strain for most cancer patients and their families. We evaluated how level of comfort and willingness to discuss important but sensitive economic topics affected longitudinal assessments of family relationships, exploring both within-person and between partner effects over 2 years after a cancer diagnosis.

METHODS

A case series of hematological cancer patient-caregiver dyads (n = 171) were recruited from oncology clinics in Virginia and Pennsylvania and followed for 2 years. Multi-level models were developed to examine the associations between comfort discussing economic aspects of cancer care and family functioning.

RESULTS

Broadly, caregivers and patients who were comfortable discussing economic topics reported higher family cohesion and lower family conflict. Dyads' assessments of family functioning were influenced both by their own and their partners level of communication comfort. Overtime, caregiver but not patients perceived a significant decrease in family cohesion.

CONCLUSIONS

Efforts to address financial toxicity in cancer care should include examination of how patients and families communicate as unaddressed difficulties can have detrimental effects on family functioning in the long term. Future studies should also examine whether the prominence of specific economic topics, such as employment status, varies depending on where the patient is in their cancer journey.

IMPLICATIONS FOR CANCER SURVIVORS

In this sample, cancer patients did not perceive the decline in family cohesion that was reported by their family caregiver. This is an important finding for future work that aims to identify the timing and nature to best intervene with caregiver supports to mitigate caregiver burden that may negatively impact long-term patient care and QoL.

Self-efficacy as mediators of the association between dyadic coping and quality of life among spousal caregiver of patients with cervical cancer

Objective

This study aims to explore the influence of dyadic coping (DC) on the quality of life (QoL) of spousal caregivers for patients with cervical cancer and to investigate the mediating role of self-efficacy in this relationship.

Methods

A convenience sample of 206 spouses of cervical cancer patients from five hospitals in Jiangsu Province, China, was included in the study. The participants completed three instruments: the 12-item Short-Form Health Survey, the General Self-Efficacy Scale, and the Dyadic Coping Inventory. Structural Equation Modeling (SEM) was used to analyze the mediating effect of self-efficacy in the DC and QoL relationship.

Results

The study found a positive correlation between self-efficacy and DC. Self-efficacy partially mediated the impact of DC on QoL, accounting for 16% of the total effect. Self-efficacy played a mediating role in facilitating the indirect positive effects of DC on QoL.

Conclusions

Spousal caregivers of cervical cancer patients frequently experience a relatively low QoL. The results suggest that interventions aimed at enhancing DC among spousal caregivers should incorporate strategies to improve self-efficacy, given its mediating role in the positive relationship between DC and QoL.

Mediating effect of social support between caregiver burden and quality of life among family caregivers of cancer patients in palliative care units

PURPOSE

To identify factors influencing the quality of life of family caregivers with terminal cancer in Chinese palliative wards and to test whether social support mediates the relationship between caregiver burden and caregiver quality of life.

METHODS

A cross-sectional study design was used. Sociodemographic data were collected and the Quality of Life Scale, the Caregiver Burden Scale, and the Social Support Rating Scale were administered to Chinese family caregivers from December 2021 to December 2022. The factors influencing quality of life and caregiver burden were examined using the Mann‒Whitney U test and the Kruskal‒Wallis H test. The mediating role of social support was assessed using the bootstrap method.

RESULTS

Family caregivers' quality of life in Chinese terminal cancer palliative units was related to caregivers' daily care time, the caregiver-patient relationship, and patient age. Caregiver quality of life was negatively associated with caregiver burden and positively associated with social support. In addition, social support mediated the relationship between caregiver burden and caregiver quality of life.

CONCLUSION

Social support mediated the impact of caregiver burden on caregiver quality of life. Family, society, and palliative care institutions should be integrated to take actions to reduce family caregiver burden, increase social support, and transfer the positive aspects of specific cultural contexts to the culture of palliative care in general to collaboratively cope with various problems related to end-stage cancer.

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.

Emotional distress, supportive care needs and age in the prediction of quality of life of cancer patients' caregivers: A cross-sectional study

INTRODUCTION

The existing literature shows a significant impact of cancer on caregivers' quality of life (QoL) and divergent results according to associated factors. To better understand the experience of cancer patients' caregivers, the present study aimed at comparing caregivers' QoL according to cancer care pathway and type of cancer, and at identifying the factors associated with their QoL.

METHODS

Caregivers were included in the study either during chemotherapy or follow-up to assess their QoL (CARGOQoL), unmet supportive care needs (SCNS-P&C), and anxiety and depression levels (HADS). CARGOQoL scores were then compared using ANOVA or Mann-Whitney non-parametric tests (objective 1). Based on univariate analyses, a multivariate analysis of covariance or linear regression model was performed for each CARGOQoL dimension (objective 2).

RESULTS

Among 583 participants (57.29% included during the follow-up phase), 523 completed the questionnaires. There was no effect of treatment phase and little effect of cancer site or disease stage on caregivers' QoL. Although significant factors associated with caregivers' QoL varied according to the dimensions assessed, the main associated factors were psychological experience (p < 0.05), satisfaction with the patient's care and supportive care needs (p < 0.01), and age of the patient or caregiver (p < 0.005).

CONCLUSION

This study shows the necessity to support caregivers during both active treatment and follow-up. It highlights the crucial role of emotional distress, supportive care and age in caregivers' QoL, regardless of the patients' oncological status.

The Dyadic Effects of Self-Efficacy on Quality of Life in Advanced Cancer Patient and Family Caregiver Dyads: The Mediating Role of Benefit Finding, Anxiety, and Depression

Objectives. To explore the dyadic interdependence of self-efficacy, benefit finding, anxiety, depression, and QOL in cancer patient (CP) and family caregiver (FC) dyads, and to ascertain the dyadic effects of self-efficacy on quality of life (QOL) in CP-FC dyads. Methods. Conducted from November 2014 to December 2015, participants comprised 772 CP-FC dyads. The study surveyed participant characteristics, self-efficacy, benefit finding, anxiety, depression, and QOL. Data were analyzed using Pearson’s correlation, T-test, and actor-partner interdependence mediation model (APIMeM). Results. CPs’ self-efficacy was positively correlated with both their own and FCs’ benefit finding and mental component summary (MCS), and negatively associated with anxiety and depression (all Ps < 0.01, |r| = 0.144∼0.432). However, CPs’ self-efficacy was only positively correlated with their own physical component summary (PCS) (r = 0.193), but not FCs’ PCS. The same profile was identified in FCs’ self-efficacy (all Ps < 0.01, |r| = 0.100∼0.468). FCs reported higher levels of self-efficacy and PCS compared to CPs (both Ps < 0.001). Significant positive correlations (r = 0.168–0.437) were identified among all paired variables in CP-FC dyads (all Ps < 0.001). To some extent, dyads’ self-efficacy influences dyads’ MCS and PCS through improving positive emotions (benefit finding) and relieving negative emotions (anxiety and depression). Conclusions. Study findings not only support the dyadic interdependence of self-efficacy, benefit finding, anxiety, depression, and QOL in CP-FC dyads but confirm the hypothesis that dyads’ self-efficacy may impact their MCS/PCS via an indirect approach to improve benefit finding and relieve anxiety and/or depression in CP-FC dyads.

Psychometric properties of the Chinese version of quality of life in life-threatening illness-family carer version

Background

The Quality of Life (QOL) in Life-threatening Illness-Family Carer Version (QOLLTI-F) has been proven to be a brief, reliable, and valid instrument for measuring the caregivers' QOL in western cultures. However, whether it is suitable to be used in Chinese culture is unclear. This study aimed to test the reliability and validity of the Chinese version of (QOLLTI-F-CV).

Materials and methods

A total of 202 family caregivers (FCs) of advanced cancer patients from Fujian Provincial hospice care center were investigated using the Chinese version of QOLLTI-F-CV from September 2019 to August 2020. The questionnaire was evaluated using an exploratory structural equation model. Its psychometric properties were examined in terms of factor structure, convergent validity, discriminant validity, internal consistency, and test-retest reliability.

Results

Differently from the seven-domain original QOLLTI-F, its Chinese version had only three domains including caregiver's self-feelings, caregiver's stress, and caregiver's outlooks. The total variance explanation rate for the domains was 55.4%. The Chinese version fitted well with the structure model (χ2 = 153.932, df = 75, P < 0.001); its comparative fit index (CFI) was 0.971; Tucker-Lewis index was 0.954; and the root mean square error of approximation (RMSEA) was 0.072. The success rate of its convergent and discriminant validity calibration test was 100%. Its Cronbach's alpha coefficient of the whole questionnaire and three domains was from 0.650 to 0.874, and test-retest reliability was 0.836.

Conclusion

The 3-domain QOLLTI-F-CV is a valid and reliable instrument for identifying QOL concerns of FCs of advanced cancer patients in China. The refactoring structure optimally matches Chinese culture and value system well.

Systematic Review and Meta-Analysis of Prevalence of Depression Among Caregivers of Cancer Patients

BACKGROUND

Caregivers of cancer patients commonly experience depressive symptoms due to the heavy burden of caregiving responsibility.

OBJECTIVE

This meta-analysis examined the prevalence of depression among caregivers of cancer patients.

METHODS

We included 85 studies covering 23,317 participants published between 2001 and 2021 (25 countries) that reported the prevalence of depression among caregivers of cancer patients. We examined the pooled prevalence of depression and hypothesized moderators, including year, age, sex, geographic regions, percentage of spousal caregivers, depression measures, and cancer stage.

RESULTS

All 85 effect sizes included 6,077 caregivers of patients with depression. The weighted average prevalence of depression was 25.14% (95% CI, 21.42-29.27%) among caregivers. The prevalence rates were moderated by geographic region, patients' cancer stage, and measures for depression. The prevalence rates also varied among the different measures assessing depression. The prevalence rate decreased with the mean age of the caregivers and the percentage of spousal caregivers.

CONCLUSIONS

This study revealed a high prevalence of depression among caregivers of cancer patients. The prevalence rates also varied with the study design, demographics of caregivers, and patients' medical information. These findings highlight that psychological support and intervention may be crucial for patients and their caregivers in clinical practice.

Associations between perceived stress and quality of life in gynaecologic cancer patient-family caregiver dyads

PURPOSE

This study aims to explore the level of stress perceived and quality of life (QOL) by gynaecologic cancer (GC) patients and family caregivers' dyads.

METHODS

In this cross-sectional study, 86 dyads were recruited from the gynaecological oncology department of a general hospital in Taichung City, Taiwan. The patients and family caregivers completed a sociodemographic information sheet, the Perceived Stress Scale, and the Taiwanese version of World Health Organization Quality of Life-BREF questionnaire. Data were analysed using descriptive statistics and Pearson's correlations. This study used the actor-partner interdependence model (APIM) with distinguishable dyads to examine the effect of patients' and caregivers' perceived stress on QOL in patient-caregiver dyads.

RESULTS

GC patients' and caregivers' level of QOL was influenced by their own stress level (actor effect). Caregivers' stress was statistically negatively associated with the patients' QOL (partner effect); however, there were no partner effect from GC patients to caregivers. Both patients and family caregivers with higher perceived stress had poorer QOL. Therefore, we identified that stress has some level of actor and partner effects on QOL in GC patient-family caregiver dyads.

CONCLUSIONS

Family caregivers' stress displayed both actor and partner effects within the first year of the cancer diagnosis; therefore, patient-and caregiver-based interventions, such as stress reduction strategies, should be developed to enhance patients' and caregivers' QOL and stress management ability.

Quality of life in cancer patients with different preferences for nurse spiritual therapeutics: The role of psychological capital

AIM

To explore the status of quality of life and psychological capital and analyse the different effects of psychological capital on the quality of life of cancer patients with different preferences for nurse spiritual therapeutics.

DESIGN

A cross-sectional survey was used.

METHODS

Two hundred and eight cancer patients were recruited using convenience sampling from a tertiary Chinese hospital, between March and July 2019. Data on preferences for nurse spiritual therapeutics (PNST), psychological capital (PsyCap) and quality of life (QoL) were collected using paper questionnaires. Hierarchical multiple regression was employed to investigate the different influences of PsyCap on QoL of cancer patients with various levels of PNST.

RESULTS

Compared with patients having high PNST, patients with mild-moderate PNST experienced lower self-efficacy, hope, optimism, PsyCap and social/family well-being. PsyCap significantly explained the variance on QoL of patients with various levels of PNST. Age, gender, presence of caregiver were significant factors influencing physical, social/family and emotional well-being of patients with high PNST.

CONCLUSION

The present study demonstrates disparities in PsyCap and QoL between cancer patients with mild-moderate and high PNST. It is essential to be aware of the positive influences of PsyCap on QoL and develop effective interventions for patients to improve their QoL, especially for those with mild-moderate PNST.

IMPACT

It is necessary to realize the benefits of PsyCap on QoL of cancer patients with various levels of PNST. Appropriate training for nurses needs to be developed to promote their spiritual care competencies. Moreover, supportive interventions should be developed for cancer patients to improve their PsyCap and QoL.

Study Protocol for the Evaluation of Individual Psychological Interventions for Family Caregivers of Advanced Cancer Patients

Background: Both anxiety and depression in family caregivers (FCs) of advanced cancer patients are common, and they have a negative influence on both the FCs and the patients. Some studies suggested that a variety of interventions could alleviate the psychological symptoms of FCs. However, there is no consensus on much more effective methods for intervention, and relatively high-quality research is blank in psychological problems of these population in China. The validity of mindfulness-based stress reduction (MBSR) and psychological consultation guided by the needs assessment tool (NST) in the psychological status of caregivers will be compared in this study to select a more suitable intervention for the FCs of advanced cancer patients in China.

Methods and Analysis: A randomized N-of-1 trial would be conducted at the Cancer Hospital, Chinese Academy of Medical Sciences. Fifty eligible FCs of advanced cancer patients will be recruited, and all will receive three cycles of psychological intervention treatment, with each cycle including both of MBSR and psychological consultation guided by the NST. MBSR and psychological consultation guided by the NST will be compared with each other in each cycle, and the intervention sequence will be based on the random number table generated after the informed consent has been completed. Each treatment period is 2 weeks, and the interval between different treatment cycles or treatment periods is 1 week. The self-reported scales are measured at the beginning and end of each treatment period, including the Self-Rating Anxiety Scale (SAS), the Self-Rating Depression Scale (SDS), Distress Thermometer (DT), Zarit Burden Interview (ZBI), Chinese version of the Medical Outcomes Study 12-item Short Form (C-SF-12), and Family Carer Satisfaction with Palliative Care scale (FAMCARE-2).

Dissemination: The protocol of the study was approved by the Institutional Review Board of the Ethical Committee of the Cancer Hospital, Chinese Academic of Medical Science. The results will be published in a peer-reviewed medical journal. The study is registered at Chinese Clinical Trials Registry with the trial registration number chiCTR2000033707. This study employs an innovative methodological approach on the effectiveness of MBSR and psychological consultation guided by the NST for psychological status of FCs of advanced cancer patients. The findings of the study will be helpful to provide high-quality evidence-based medical data for psychological intervention of FCs of advanced cancer patients, and guide clinicians on best quality treatment recommendations.

The dyadic relationship of benefit finding and its impact on quality of life in colorectal cancer survivor and spousal caregiver couples

OBJECTIVES

To explore the benefit finding (BF) relationship between colorectal cancer (CRC) survivors and their spousal caregivers, and to discover the dyadic impact of BF on quality of life (QOL) in CRC survivor and spousal caregiver couples.

METHODS

Conducted from May 2018 to December 2018, the study included 286 couples consisting of CRC survivors and their spousal caregivers. The study survey evaluated participants' BF, anxiety, depression, and QOL. Data analysis methods included Pearson's correlation, paired t test, and the actor-partner interdependence mediation model (APIMeM).

RESULTS

CRC survivors and spousal caregivers reported comparable moderate to high BF experience (ranging from 68.9 to 80.8%). Moderate to high correlations were found between CRC survivors and their spousal caregivers in all of the paired BFs (including the overall BF scale and three factors) (all Ps < 0.001, r = 0.461-0.612). We found significant positive correlations of the same measures between dyads of CRC survivors and spousal caregivers (r = 0.331-0.612), including BFS-C (overall BF scale and three subscales), HADS-C (anxiety and depression), PCS, and MCS. To a certain degree, BF exerts an impact on couples' QOL through the mediating effect of psychological distress (anxiety and depression).

CONCLUSIONS

The present study further confirms the dyadic interdependence between BF, anxiety, depression, and QOL in couples coping with CRC. In addition, the APIMeM findings may support the proposed mechanism, in that buffering against negative emotions (psychological distress) is an approach in which BF plays an important role, e.g., improves QOL, in the context of a stressful process.
