Do concordances of social support and relationship quality predict psychological distress and well-being of cancer patients and caregivers?

The Association between Relationship Satisfaction Concordance and Breast Cancer Survivors' Physical and Psychosocial Well-Being

The purpose of this article is to examine the association of relationship satisfaction concordance between breast cancer survivors (BCSs) and their partners with matched controls on physical and psychosocial outcomes. Dyads of BCSs, age-matched controls, and partners were recruited as part of a larger, cross-sectional QOL survey study. Relationship concordance was measured by the ENRICH marital satisfaction score, with each dyad's score equaling the absolute value of the difference in satisfaction between survivor/control and their partner (lower score = greater concordance). Dependent variables for survivors/controls were social constraint, physical function, depression, fatigue, attention function, and sleep disturbance. Relationship satisfaction and concordance were used as the primary independent variables, while controlling for dyad category, race, education, income, and age within multiple linear regression models. The sample consisted of 387 dyads (220 BCSs, 167 controls). Relationship satisfaction concordance ranged from 0 to 53.4 (mean = 10.2). The BCS dyads had significantly worse concordance (11.1) than the controls (9.1) (p = 0.050). Within the multiple regression models, lower concordance was significantly associated with increased social constraint (p = 0.029), increased depression (p = 0.038), and increased fatigue (p = 0.006). Poor relationship satisfaction and concordance were significantly associated with poor physical and psychosocial outcomes. The maintenance of relationships should remain a focus through difficulties of cancer and into survivorship for survivors, partners, and providers.

Better together: Relationship quality and mental health among cardiac patients and spouses

Reductions in marital relationship quality are pervasive post-cardiac event. It is not yet understood how relationship quality is linked to mental health outcomes in couples where one member has established cardiovascular disease (CVD) and the interdependence within dyads is seldom measured. This research is required as psychological distress has been independently linked to CVD incidence, morbidity, and mortality. This study assessed associations of relationship quality with depression and anxiety among patients with CVD and their spouses. Participants completed questionnaires measuring four dimensions of relationship quality and mental health. Data were analyzed using an Actor-Partner Interdependence Model with hierarchical moderation analyses. 181 dyads (N = 362 participants) comprised the study sample. Most patients had coronary artery disease (66.3%) and 25.9% were female. Patients reported higher relationship satisfaction and fewer anxiety symptoms than did spouses. Patients and spouses with high dyadic consensus and affectional expression reported fewer mental health symptoms, but only when the other partner also perceived high levels of consensus and affectional expression in the relationship. Patients and spouses with low dyadic cohesion reported worse mental health symptoms (actor effects), but those effects were no longer significant when both the patient and the spouse appraised the relationship as having high levels of dyadic cohesion. Taken together, relationship quality is linked to mental health symptoms in patients with CVD and their spouses. Longitudinal and experimental studies are now warranted to further substantiate the cross-sectional findings of this study.

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.

Psychological distress among Chinese patients with breast cancer undergoing chemotherapy: Concordance between patient and family caregiver reports

AIMS

To examine patient-caregiver concordances about psychological distress among Chinese patients with breast cancer undergoing chemotherapy and identify factors related to concordance among patients and family caregivers.

DESIGN

Cross-sectional study.

METHODS

From October 2019 to June 2020, 137 patient-caregiver dyads were enrolled. Sociodemographic information, the distress thermometer (including the problem list), the Distress Disclosure Index and the Family Adaptability and Cohesion Evaluation Scale were used to collect data. Data were analysed using intraclass correlation coefficients (ICC), kappa statistics, two related samples test, chi-square tests and/or Fisher's exact tests and binary logistic regression.

RESULTS

Overall, fair agreement was identified between patients' and caregivers' reports (intraclass correlation coefficients [ICC] = .528). Patients reported significantly higher psychological distress scores than paired caregiver reports. Lower psychological distress concordance was found among patients with comorbidities (odds ratio [OR], 0.352; 95% confidence interval [CI], 0.155-0.798) and lower levels of self-disclosure (OR, 0.402; 95% CI, 0.186-0.868).

CONCLUSION

There was relatively low concordance between patients' reports and caregivers' perceptions of psychological distress. Family caregivers tended to underestimate patients' psychological distress. A comorbid condition and lower levels of self-disclosure contributed to this bias.

IMPACT

Having an awareness of the incongruence between patient and caregiver may help healthcare providers better interpret caregiver assessments. Healthcare providers should reinforce patient-caregiver dyadic psychosocial education to improve concordance. More psychological care and substantial emotional support should be provided for Chinese breast cancer patients undergoing chemotherapy by family caregivers and healthcare providers.

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

OBJECTIVE

Caregivers for patients with cancer have an integral role in maintaining patients' health. Although patients and caregivers experience the impact of cancer individually, studies suggest their health is interdependent. The objective of this review was to synthesize the literature on interdependent physical and psychological morbidity in patient-caregiver dyads published since 2016.

METHODS

A search of PubMed, CINAHL, Embase, and PsycInfo databases was performed using Cooper's recommendations and the Preferred Reporting Items for Systematic Reviews And Meta-Analyses Guidelines. Studies were included if they measured individual physical or psychological morbidity in cancer patient-caregiver dyads, evaluated interdependence, and were published in a peer-reviewed journal.

RESULTS

Twenty-three studies met criteria, characterized by mainly spousal dyads. Studies included a variety of cancers and methodologies. Findings were inconsistent, indicating varying interdependence. However, the studies demonstrated a stronger relationship between patients' and caregivers' psychological morbidity than between their physical morbidity.

CONCLUSIONS

This review revealed a need for continued exploration of dyadic health interdependence. Future studies should consider samples of patients with a single type of cancer, testing cultural mediators/moderators, and using longitudinal designs.
