Double Burdens and Double Resilience: Dynamic Interactions in Older Couples Living With Multimorbidity

To explore the lived experiences and daily interactions of older couples living with multimorbidity.

A descriptive-interpretive qualitative study based on a generic interpretive description framework.

A total of 20 dyads were recruited using a purposive sampling strategy, and 24 semi-structured in-depth interviews were conducted between May 2023 and January 2025. Reflexive thematic analysis was used to analyse data.

Four overarching themes were generated: (1) dynamic relationship structures; (2) diverse interaction patterns; (3) double burdens; and (4) double resilience. Dynamic relationship structures occurred in dyadic and triadic forms. Diverse interaction patterns involved independence, interdependence and dependence. Double burdens manifested as physical toll, financial hardship, emotional contagion and perceptual misalignment, whereas double resilience was reflected in the nudge effect, emotional resonance and promotion of family ownership of health.

This study adopted a dyadic perspective to explore the experiences and interactions of older couples living with multimorbidity. The caring dynamics and blurred roles of patient and care partner deviate from the traditional unidirectional, linear model of 'one person caring for the other'. Formal or informal caregiving support from third parties, as well as the nudge effect and emotional resonance between spouses, may help orient older couples as they navigate the challenges associated with multimorbidity.

Our findings indicate that community nurses can play a proactive role in identifying older couples living with multimorbidity through routine care attendance and assessments, enabling early recognition of health management needs. Geriatric nurses can leverage insights into couples' interaction patterns to tailor more effective care plans at different stages of illness, monitor emerging risks and identify optimal timing for third-party support. By facilitating a responsive triadic network, nurses can help ensure continuous and sustainable health care.
