Perceived social support and distress in carers of people with lung cancer: The serial mediation of resilience and positive aspects of caregiving

Mediating and moderating roles of individual resilience, caring ability and social support: a cross-sectional study on the association between family resilience and caregiving burden among primary family caregivers of cancer patients in China

OBJECTIVES

This study aimed to evaluate the caregiving burden among primary caregivers of cancer patients, clarify the relationship between family resilience and caregiving burden, and explore the mediation and moderation effects.

DESIGN

A cross-sectional study design was used.

SETTING

The study was conducted at a specialised tumour hospital in Harbin, China.

PARTICIPANTS

The study included a sample of 402 primary family caregivers of patients with cancer. Ultimately, 367 participants completed valid questionnaires, yielding a response rate of 91.2%.

OUTCOME MEASURES

Participants completed scales evaluating caregiving burden, caring abilities, individual resilience, family resilience and social support. We performed structural equation modelling to analyse mediation and moderation effects.

RESULTS

Out of 367 responses, approximately 50% of primary family caregivers reported moderate to severe caregiving burden. Family resilience was found to reduce caregiving burden (β=-0.386, p=0.005), while individual resilience fully mediated the relationship between family resilience and caregiving burden (95% CI -0.659 to -0.161). Caring ability moderated both the first and second halves of the mediating path. Furthermore, social support doubly moderated the moderating role of caring ability in both the first and second halves of the mediating path.

CONCLUSIONS

This study demonstrated the mediating role of individual resilience and the moderating roles of caring ability and social support in the relationship between family resilience and caregiving burden. We suggest that medical institutions should enhance caregiving training and psychological counselling services. Additionally, the government should collaborate with medical institutions and social organisations to improve social welfare policies and the medical insurance system.

A Latent Class Analysis of Resilience and Its Relationship With Care Burden and Psychological Distress in Family Caregivers of Older Adults With Disability

Given the challenging circumstances of aging with disability, family caregivers (FGs) face significant strain. Resilience, however, is a crucial protective factor against adverse caregiving outcomes. The study thus aimed to determine the latent classes of resilience among FGs and examine how these classes are related to care burden and psychological distress. This was a cross-sectional descriptive study that included 248 FGs in China. Latent class analysis was conducted to determine the classes of resilience exhibited by FGs. The study revealed four distinct classes of resilience: the high resilience class, high tenacity but moderate strength-optimism class, moderate resilience but low autonomy class, and low resilience class. FGs with secondary caregivers and those who were older were more likely to be part of the high resilience class. Furthermore, caregivers in the high resilience class had significantly lower burdens, less psychological distress, and greater resilience. Therefore, family caregivers' resilience can be classified according to characteristics; more attention should be given to caregivers who are younger and lack the support of secondary caregivers; and targeted interventions should be developed based on resilience classification characteristics.

Moderators of interdependent psychological distress in cancer survivor-caregiver dyads

BACKGROUND

The purpose of this study was to test dyadic interdependence in psychological distress (anxiety and depressive symptoms) and explore moderators of interdependence among cancer survivors in treatment and their informal caregivers.

METHODS

Cancer survivors and their caregivers completed measures of anxiety and depressive symptoms, social support, social isolation, and burden of other symptoms, at three points in time over the course of 17 weeks.

RESULTS

In 315 dyads, depressive symptoms and anxiety were transmitted from caregivers to survivors. Survivors with high symptom burden or low social support were especially influenced by caregivers' depressive symptoms. Caregivers who had high social isolation or low social support were most likely to be influenced by survivors' depressive symptoms.

CONCLUSION

Psychological distress is transmitted within dyads during cancer treatment. Dyadic interdependence was most pronounced from caregivers to survivors. Symptom burden, social isolation, and low social support enhanced this dyadic interdependence.

Nurses' Sleep Quality and Its Influencing Factors During the First Explosive COVID-19 Outbreak in Zhejiang, China, After the Relaxation of Epidemic Prevention and Control Measures: A Multicentre Cross-Sectional Study

AIM

To investigate the sleep quality and its influencing factors among nurses in hospitals in Zhejiang, China, during the first explosive COVID-19 outbreak following the relaxation of prevention and control measures.

DESIGN

A multicentre cross-sectional study.

METHODS

Between 10 January and 20 January 2023-approximately 1 month after the policy was loosened-a total of 573 nurses from tertiary and community hospitals in Zhejiang participated in an online, self-administered survey. The participants were recruited using convenience sampling, and the survey was distributed via the WeChat platform. The survey included a general information form; the Self-Rating Scale of Sleep (SRSS); the Depression, Anxiety, and Stress Scale-21 (DASS-21); the Perceived Social Support Scale (PSSS); and the Brief Resilience Scale (BRS). Data analysis was conducted using SPSS version 26.0. Statistical methods employed included t-tests, one-way analysis of variance (ANOVA), chi-square tests and Mann-Whitney U-tests for comparisons between groups. Pearson correlation coefficients were calculated to analyse the relationship between the SRSS score and the DASS-21, PSSS and BRS scores. A multiple linear stepwise regression analysis was conducted to determine the independent influencing factors of sleep quality.

RESULTS

More than 90% of the nurses were infected with COVID-19, and 60.6% had sleep disorders. The regression analysis revealed that anxiety, the BRS score, comorbidities, hospital grade, clinical front-line, age and COVID-19 infection independently predicted sleep quality. The scores for several SRSS items were higher than the Chinese norm, especially for the nurses in tertiary hospitals.

Social Support, Depression and Anxiety in Cancer Patient-Relative Dyads in Early Survivorship: An Actor-Partner Interdependence Modeling Approach

OBJECTIVE

Cancer places a psychological burden on both patients and their relatives. Perceived social support influences the extent of psychological distress. Our aim was to investigate associations between positive support, detrimental interactions, depression and anxiety in patient-relative dyads in the initial period after diagnosis.

METHODS

Patients with a solid tumor and their relatives participated in this prospective, multicenter observational study. Participants answered validated measures including the Illness-specific Social Support Scale (SSUK-8), the Patient Health Questionnaire (PHQ-9) and the General Anxiety Disorder Scale (GAD-7). We analyzed cross-sectional data from the initial time following diagnosis with paired t-tests and actor-partner interdependence models.

RESULTS

A total of 347 dyads of patients (mean age 59.9 years) and their relatives (mean age 56.7 years) participated. Compared to their relatives, patients reported significantly higher levels of depression (patients: M = 6.31, SD = 4.94; relatives: M = 5.44, SD = 4.77) and lower levels of anxiety (patients: M = 4.40, SD = 4.10; relatives: M = 4.98, SD = 4.47) as well as more positive support (patients: M = 14.31, SD = 2.07; relatives: M = 12.46, SD = 3.29) and a lower frequency of detrimental interactions (patients: M = 3.21, SD = 2.97; relatives: M = 3.66, SD = 2.93). Intrapersonal effects: Positive support was associated with lower distress only for relatives, whereas detrimental interactions were associated with higher distress for both patients and relatives (all p < 0.05). Interpersonal effects: More positive support and fewer detrimental interactions experienced by relatives were associated with lower patient distress (all p < 0.05).

CONCLUSIONS

Better support for relatives may not only reduce their own distress, but also patients' distress. Relatives experience similar levels of distress and poorer social support than patients.

Influence of Health System Affiliation and Pain Manifestation on Advanced Oral Cavity Squamous Cell Carcinoma Risk: A Retrospective Cohort Study in a Latin American Population

Background/Objectives: Oral cavity cancer, a subtype of head and neck cancer, is one of the most common malignancies globally. This study assessed the influence of health system affiliation and pain manifestation on the risk of advanced oral cavity squamous cell carcinoma (OCSCC) in a Latin American population. Methods: In this retrospective cohort study, we analyzed medical records from 2015 to 2016, including data from the past 19 years, of 233 patients with OCSCC treated at a public hospital in Medellín, Colombia. Sociodemographic and clinical variables were evaluated, and multivariate regression models incorporated variables significant in bivariate analysis. Results: Among 233 patients, 196 (84.1%) had advanced OCSCC. The sample had a mean age of 63 ± 13 years, 53.6% were male, and 64% came from urban areas with predominantly low socioeconomic levels. Men showed a threefold increased risk of advanced OCSCC (95% CI: 1.3-6.8), while patients referred to pain clinics exhibited a 19.5 times higher risk (95% CI: 2.3-159.5). Patients in the subsidized health system or without health insurance had 2.6 (95% CI: 1.07-6.3) and 2.7 times (95% CI: 1.17-6.4) higher risks, respectively. Conclusions: This study found that male patients, referrals to pain clinics, and subsidized or no health system affiliation significantly increased the risk of advanced OCSCC.

Does Family Functioning Matter? Understanding the Relationship Between Family Interactions and Depressive Symptoms for Caregivers of Cancer Patients

BACKGROUND

Caregivers of cancer patients are at increased risk of depression and other health challenges. There is limited understanding of the role of the caregiver's own family members in promoting or discouraging mental wellbeing. Family functioning conceptualizes how family members interact to promote a positive family environment and has the potential to impact caregiver mental health. The purpose of this study is to assess the association between family interactions and depressive symptoms among family caregivers of cancer patients.

METHODS

Secondary analysis of baseline data from an NIH-funded randomized control trial of family caregivers of cancer patients recruited from academic palliative care clinics at three sites (2 Midwest, 1 East). We tested for an association between caregiver responses to the Family Quality of Life in Dementia-Family Interactions Subscale and Patient-Reported Outcomes Measurement Information System Depression Short Form 8A using a block-wise approach to linear modeling.

RESULTS

A total of 246 caregivers were included in analysis; caregivers were mostly White (82%), not Hispanic or Latina/o (96%), and female (65%), with an average age of 55 years. Overall, participants had high family interactions (mean 57.7, sd 11.7) and an average depressive symptom burden (t-score 52.4, SD 8.57). Family interactions was significantly negatively associated with depressive symptoms (b = -.163, se = .057) when accounting for relevant covariates.

CONCLUSION

Family caregivers with more positive family interactions are likely to have fewer depressive symptoms, suggesting family functioning may play a key role in bolstering family caregiver mental health and wellbeing.

A chain mediation model reveals the association between family sense of coherence and quality of life in caregivers of advanced cancer patients

Caregivers of advanced cancer patients face challenges impacting their quality of life (QoL). While evidence suggests that family sense of coherence (FSOC) can enhance individual psychological well-being and reduce distress symptoms, the precise mechanism through which FSOC improves caregivers' QoL remains unclear. This study aimed to explore the relationships among FSOC, psychological resilience, psychological distress, and QoL in primary caregivers of advanced cancer patients. A cross-sectional observational study was undertaken from June 2020 to March 2021 across five tertiary hospitals in China. Instruments included a general characteristic questionnaire, the Family Sense of Coherence Scale, the Patient Health Questionnaire-4, the 10-item Connor-Davidson Resilience Scale, and the 8-item SF-8 health survey. Pearson's correlation and chain mediation analyses were performed using IBM SPSS (version 21) and PROCESS macro (version 3.4). Out of 290 valid questionnaires, results demonstrated that FSOC directly and positively influences caregivers' QoL. Psychological distress partially mediated the FSOC-QoL association, with paths "FSOC-psychological distress-QoL" and "FSOC-psychological resilience-psychological distress-QoL" contributing 43.08% and 6.72% of the total effect, respectively. Furthermore, this study distinguished physical and mental aspects of QoL, confirming both conform to the chain mediation model. FSOC impacts caregivers' QoL directly and indirectly through the mediation of psychological distress and the chain mediation effect of "psychological resilience-psychological distress". These insights enhance our understanding of the complex interplay between FSOC and QoL, underscoring the potential benefits of bolstering FSOC to strengthen caregiver resilience, alleviate distress, and ultimately elevate their QoL.

Disparities in lung cancer short- and long-term outcomes after surgery: Analysis from the national cancer database

INTRODUCTION

Social determinants of health are particularly important in lung cancer epidemiology. Previous studies have primarily associated social determinants with long-term outcomes, such as survival, but fail to include short-term outcomes after surgery. The National Cancer Database (NCDB) was used to draw associations between social factors of patients with lung cancer and short-term post-surgical outcomes, while comparing them to prognostic factors, including stage at diagnosis and survival.

METHODS

The 2004-17 NCDB was queried for patients with primary epithelial tumor, squamous cell carcinoma, or adenocarcinoma of the lung treated with curative intent. Linear, binary logistic, Kaplan-Meier, and Cox proportional hazards regression models were utilized.

RESULTS

On logistic regression modeling, male gender, low income, lacking insurance, and facility in the central United States were associated with poor short-term outcomes (<0.05). Increased age, White race, and Black race were associated with increased length of hospital stay and mortality, but negatively correlated with readmission rates (<0.05). Medicare and Medicaid were associated with increased length of stay and mortality, respectively (<0.05). Similar patterns were observed for higher stage at diagnosis (<0.05). Hazard ratios were elevated with increased age, male gender, White race, lacking insurance, Medicaid, and facility in the central United States (<0.05).

CONCLUSION

Many social factors previously associated with poor prognosis after lung cancer diagnosis are also associated with poor short-term outcomes after surgery. This study implies that healthcare providers treating lung cancer should proceed with care while aware that patients with the discussed social factors are predisposed to complicated recoveries.

Dyadic effects of social support, illness uncertainty on anxiety and depression among lung cancer patients and their caregivers: a cross-sectional study

OBJECTIVES

To explore the dyadic relationships between perceived social support, illness uncertainty, anxiety, and depression among lung cancer patients and their family caregivers. To examine the potential mediating role of illness uncertainty and the moderating role of disease stage in lung cancer patient-caregiver dyads.

METHODS

A total of 308 pairs of lung cancer patients and their family caregivers from a tertiary hospital in Wuxi, China, from January 2022 to June 2022 were included. Participants' perceived social support, illness uncertainty, anxiety, and depression were assessed by corresponding questionnaires. To test for dyadic relationships between the variables, we employed the actor-partner interdependence mediation model.

RESULTS

There were actor and partner effects of both patient and caregiver perceived social support on anxiety and depression, and illness uncertainty mediated the effect of perceived social support on anxiety and depression. Lung cancer stage plays a moderating role in lung cancer patient-caregiver dyads. There is an indirect positive partner effect of perceived social support from family caregivers on anxiety and depression in patients with early lung cancer; there is a direct or indirect negative partner effect of social support from family caregivers on anxiety and depression in patients with advanced lung cancer.

CONCLUSIONS

This study confirmed the dyadic interdependence between perceived social support, illness uncertainty, anxiety, and depression among lung cancer patients and family caregivers. Furthermore, studies on differences between different lung cancer stages may provide a theoretical basis for different dyadic supportive interventions based on lung cancer stages.

The Effects of Laughter Yoga on Perceived Stress, Positive Psychological Capital, and Exercise Capacity in Lung Cancer Chemotherapy Patients: A Pilot Randomized Trial

BACKGROUND

Lung cancer is the malignant tumor with the highest morbidity and mortality rate in China. Although chemotherapy is effective in improving clinical symptoms, it causes a variety of acute and chronic side effects, seriously aggravating the psychological stress of patients. Laughter Yoga as a new type of aerobic exercise can effectively reduce stress levels and increase positive mood in patients. This study aimed to examine the effects of laughter yoga on perceived stress, positive psychological capital, and exercise capacity in lung cancer patients.

METHODS

This study was a randomized, single-blind, parallel-group trial. The study enrolled 84 lung cancer chemotherapy patients from a general hospital in central China. These patients were randomly allocated to control and intervention groups (n = 42 per group) after baseline assessments. Patients in the control group received routine care and those in the intervention group received laughter yoga intervention. Perceived stress, positive psychological capital, and exercise capacity were assessed at baseline, immediately post-intervention.

RESULTS

During the implementation of the study, there were 2 dropouts in each of the intervention and control groups. Ultimately, 80 patients in the control and intervention groups completed the trial. Patients who received laughter yoga intervention had significantly higher scores in positive psychological capital (P < .01, Cohen's d = 0.692) and exercise capacity (P < .01, Cohen's d = 0.659). Discernible differences were also observed in perceived stress (P < .01, Cohen's d = 1.087) between the 2 groups.

CONCLUSIONS

The results of this study suggest that laughter yoga is an effective way and may produce beneficial effects on perceived stress, positive psychological capital and exercise capacity.

A qualitative meta-synthesis of the caregiving experiences of adult children providing care for cancer patients in China: Implications for multidisciplinary healthcare teams

Qualitative meta-synthesis is a coherent approach to answering an overarching research question by synthesising past qualitative studies so as to create new meanings from their results. We conducted a qualitative meta-synthesis to systematically evaluate and integrate the caregiving experiences of adult children providing care for an elderly parent with cancer. The search was conducted in the databases Web of Science, PubMed, Embase, MEDLINE, Cochrane Library, Grew Literature in the Health Sciences, CNKI, WanFang Data, VIP, SINOMED and China Academic Journals as well as Chinese grey literature databases (China Academic Conference Literature Database/, National Science and Technology Library) from inception to June 9, 2021. Thirteen studies were included in the final synthesis. The caregiver experiences they describe are synthesised into three primary themes: care needs, care burden and care gains, with numerous secondary themes. Besides our findings that seem to align with those from studies focused on other cultures, we have highlighted three main discoveries from the synthesis that stand out in the Chinese context: (1) many sub-themes related to specific caregiving skills; (2) a strong expectation for health professionals to improve their communication skills with family caregivers; (3) the negative and positive influences of filial piety in caregiving experiences. Our findings can help multidisciplinary healthcare teams in China support adult children as caregivers in their emphasis on improving caregiver education and training, ways of making the most of potential care gains, and ways of easing care burdens.
