Examining how congruence in and satisfaction with dyadic care type appraisal contribute to quality of life in heart failure care dyads

Dyadic Appraisals of Family Decisions and Health Tasks in Midlife-Older Couples

Shared appraisals and collaboration within couples play important roles in optimizing health. Less is known about concordance regarding collaboration, factors associated with concordance, and implications for health. Data from 2,761 couples from the Health and Retirement Study (2014/2016 and 2016/2018 waves) were examined to determine within-couple concordance in completion of two tasks (family decisions and medical forms). The majority of couples were concordant regarding who makes family decisions (69.7%) and who completes medical forms (64.4%); 62% agreed they make family decisions collaboratively versus 25.5% completing medical forms collaboratively. Concordance was significantly associated with greater marital support and longer marital duration. Concordance was not significantly associated with depressive symptoms 2 years later, but the link between concordance in making major family decisions and self-rated health differed by age and gender. Future research at the intersection of concordance and collaboration may shed important light on how older couples navigate tasks and decisions.

Dyadic relationships between informal caregivers and older adults with chronic heart failure: a systematic review and meta-synthesis

AIMS

To synthesize the qualitative evidence on dyadic relationships between informal caregivers and older adults with chronic heart failure (HF).

METHODS AND RESULTS

A systematic review and meta-synthesis were conducted. Eight databases were searched for English peer-reviewed studies and grey literature published from inception to 27 February 2024. Qualitative and mixed-method studies involving older adults ≥55 years old with chronic HF and discussing patient-caregiver relationships in community settings were included. Data were synthesized using Sandelowski and Barroso's two-step framework. A meta-summary was developed using thematic analysis, and findings were synthesized using the Theory of Dyadic Illness Management. Twenty-four studies from 2008 to 2024 were included (n = 580 participants). The meta-summary consisted of four themes and nine subthemes: (i) Characteristics of dyad relationships, (ii) How both parts of the dyad care for each other, (iii) Chronic HF and dyad relationships, and (iv) Knowledge of managing chronic HF. These were reorganized into the meta-synthesis: dyadic appraisal, dyadic management behaviours, dyadic health, contextual factors affecting dyadic relationships and management behaviours, and illness management as a dyadic phenomenon.

CONCLUSION

Investigating relationship dynamics and their impact on dyads and chronic HF self-care is vital. Where possible, healthcare providers should prioritize dyadic care when caregivers are involved and deliver individualized care to improve patient and caregiver outcomes. Assessing and optimizing dyadic relations, addressing individual perceptions and needs as part of clinical care, and before implementing self-care interventions in research may help ensure that self-care is appropriately tailored and would not be hindered by relationship conflicts.

Psychometric testing of the Care Dependency Scale in patients with heart failure and their caregivers

AIMS

This study aims to (i) test the validity and reliability of the Care Dependency Scale (CDS) for patients with heart failure (HF) and (ii) test the validity and reliability of the proxy version of the CDS assessing informal caregivers' perception of the dependency level of individuals with HF.

METHODS AND RESULTS

Secondary data analysis was conducted of transnational multicentre cross-sectional design study. A convenience sample comprised of HF patients-informal caregivers' dyads in three European countries. The CDS was administered to patients and the proxy version to informal caregivers. Factorial validity was tested for each scale using confirmatory factor analysis. Reliability was evaluated with the composite coefficient and Cronbach's alpha. Construct validity was tested via known group differences. Measurement error was tested to assess responsiveness to changes. A total of 229 patients and 208 caregivers were recruited. Confirmatory factor analysis supported the two-factor structure (Physical Care Dependency and Psychosocial Care Dependency) of the CDS in both HF patients and their caregiver. Reliability estimates were adequate for all reliability coefficients. Construct validity was supported. The measurement error was adequate.

CONCLUSION

The scale shows acceptable validity and reliability and can be useful for care dependency assessment of patients with HF and their informal caregivers. Further research is needed for assessing the validity and reliability in other cross-cultural settings. The use of the CDS has the potential to effectively enable the development of pertinent care plans, taking dependency into consideration including the perspective of both members of the dyad as a whole.

The Context of Caregiving in Heart Failure: A Dyadic, Mixed Methods Analysis

BACKGROUND

Caregiving for persons with heart failure (HF) varies based on the individual, family, and home contexts of the dyad, yet the dyadic context of HF caregiving is poorly understood.

OBJECTIVE

The aim of this study was to explore dyadic perspectives on the context of caregiving for persons with HF.

METHODS

Family caregivers and persons with HF completed surveys and semistructured interviews. Investigators also photographed caregiving areas to complement home environment data. Descriptive qualitative analysis resulted in 7 contextual domains, and each domain was rated as strength, need, or neutral. We grouped dyads by number of challenging domains of context, categorizing dyads as high (≥3 domains), moderate (1-2 domains), or minimal (0 domains) needs. Quantitative instruments included the 36-item Short Form Health Survey, ENRICHD Social Support, HF Symptom Severity, and Zarit Burden Interview. We applied the average score of each quantitative measure to the groups derived from the qualitative analysis to integrate data in a joint display.

RESULTS

The most common strength was the dyadic relationship, and the most challenging domain was caregiving intensity. Every dyad had at least 2 domains of strengths. Of 12 dyads, high-needs dyads (n = 3) had the worst average score for 7 of 10 instruments including caregiver and patient factors. The moderate-needs dyads (n = 6) experienced the lowest caregiver social support and mental health, and the highest burden.

CONCLUSION

Strengths and needs were evident in all patient-caregiver dyads with important distinctions in levels of need based on assessment of multiple contextual domains. Comprehensive dyadic and home assessments may improve understanding of unmet needs and improve intervention tailoring.
