Dyadic associations of psychological resilience, positive coping, and psychological distress among patients with decompensated cirrhosis and their family caregivers: a cross-sectional actor–partner interdependence model study

This cross-sectional study of 265 patient–caregiver dyads with decompensated cirrhosis reveals that psychological resilience and positive coping not only reduce individual distress but also significantly alleviate distress in their partners, highlighting the interdependent nature of psychological well-being within these relationships.

When a person faces a serious, long-term illness, they rarely face it alone. They are usually surrounded by family members who step in to help with daily tasks, manage medications, and offer emotional support. This creates a unique partnership where the health of one person is deeply tied to the health of the other. In the world of medical research, scientists are increasingly interested in how these pairs, known as dyads, influence each other's mental well-being. Two key ideas help explain this connection: resilience and coping. Resilience is the inner strength that helps a person bounce back from stress and keep their balance during hard times. Coping refers to the specific thoughts and actions people use to handle difficult situations, such as solving problems or managing their emotions. While we know that stress can be heavy for both the patient and the helper, it is not always clear how the mental strength of one person affects the other, or how their ability to handle stress works together as a team.

A new study published in October 2026 explores these connections specifically among patients with decompensated cirrhosis and their family caregivers. Decompensated cirrhosis is a severe stage of liver disease where the organ can no longer function properly, leading to complications like fluid buildup, bleeding, and confusion. The condition is unpredictable and often requires frequent hospital visits, placing a heavy burden on both the patient and the family member who cares for them. Researchers wanted to understand if the mental toughness and positive problem-solving skills of the patient and the caregiver were linked, and if these traits helped reduce feelings of anxiety, sadness, or distress for both members of the pair. To do this, they used a statistical approach that treats the patient and caregiver as a single unit of analysis, rather than looking at them as two separate people. This method allows scientists to see how one person's traits might directly influence the other person's feelings.

The researchers recruited 265 pairs of patients and their primary family caregivers from a hospital in Anhui, China. Each pair completed a series of questionnaires designed to measure their psychological distress, their level of resilience, and how often they used positive ways to cope with stress. The results revealed a clear picture of the emotional landscape for these families. The patients reported higher levels of psychological distress than their caregivers, with average scores indicating a significant burden. In contrast, the caregivers showed higher levels of resilience and a greater tendency to use positive coping strategies. This suggests that while the family members are under pressure, the patients are carrying the heaviest emotional load of the disease itself.

Beyond these individual differences, the study found a strong link between the two people in each pair. When a patient felt high levels of distress, their caregiver tended to feel high levels of distress as well. This connection was so strong that the emotional states of the patient and caregiver moved in sync. Furthermore, the study showed that resilience and positive coping acted as protective shields for both members. When either the patient or the caregiver had strong resilience or used positive coping methods, it was associated with lower distress for both of them. This means that the mental strength of one person did not just help themselves; it also seemed to lift the emotional burden of the other person in the relationship.

The researchers also looked at how these protective factors worked together. They found that the patient's own resilience and coping skills were linked to the distress levels of both the patient and the caregiver in a very balanced way. If the patient felt strong and handled stress well, both the patient and the caregiver felt less distressed. However, the pattern was slightly different for the caregivers. While a caregiver's own resilience and coping skills strongly helped reduce their own distress, their influence on the patient's distress was present but less direct. This suggests that while a caregiver's ability to stay calm and solve problems is vital for their own well-being, it does not automatically translate into the same level of relief for the patient. The patient's own ability to cope appears to be the more central force in keeping the emotional balance of the pair steady.

These findings suggest that psychological distress in severe liver disease is not just an individual experience but a shared one. The mental health of the patient and the caregiver are interdependent, meaning that what happens to one affects the other. The study indicates that interventions designed to help these families should look at the pair as a whole unit. Strengthening the resilience and coping skills of the patient may have a ripple effect that benefits the caregiver, while supporting the caregiver's ability to manage stress can also help maintain a stable environment for the patient. By understanding these connections, healthcare providers can better support families navigating the challenges of decompensated cirrhosis, recognizing that helping one person often means helping the other.

Technical Summary: Dyadic Associations of Psychological Resilience, Positive Coping, and Psychological Distress in Decompensated Cirrhosis

Problem Statement
Decompensated cirrhosis presents a complex clinical challenge characterized by ascites, variceal bleeding, hepatic encephalopathy, and frequent hospitalizations, leading to significant symptom burden and prognostic uncertainty. While psychological distress is a critical outcome for nursing assessment in this population, existing research has predominantly treated patients and family caregivers as independent units of analysis. This approach fails to account for the statistical non-independence and psychological interdependence inherent in the caregiving dyad. Furthermore, while psychological resilience and positive coping are known protective factors, their joint roles and specific actor (self-to-self) and partner (self-to-other) associations within patient–caregiver dyads affected by decompensated cirrhosis remain unclear.

Methodology
This study employed a cross-sectional design utilizing the Actor–Partner Interdependence Model (APIM) to analyze dyadic data.

Participants: 265 matched patient–caregiver dyads were recruited via convenience sampling from a tertiary center (Anhui Public Health Clinical Center) between November 2025 and February 2026. Patients met diagnostic criteria for decompensated cirrhosis, were aged ≥18, and had a primary family caregiver.
Measures:
- Psychological Distress: Assessed using the Kessler Psychological Distress Scale (K10).
- Psychological Resilience: Measured via the Connor–Davidson Resilience Scale (CD-RISC).
- Positive Coping: Evaluated using the positive coping dimension of the Simplified Coping Style Questionnaire.
Statistical Analysis:
- Differences between patients and caregivers were analyzed using the Wilcoxon signed-rank test.
- Correlations were examined using Spearman rank correlation analysis.
- APIMs were constructed in R (version 4.4.2) using the lavaan package to estimate actor and partner effects. Two unadjusted saturated models were built: one linking resilience to distress and another linking positive coping to distress.
- Bootstrap resampling (5,000 replications) was used to estimate the ratio of partner effects to actor effects ( $k$ ) to determine dyadic patterns (e.g., couple pattern vs. mixed pattern).

Key Results

Group Differences: Patients reported significantly higher psychological distress ( $27.76 \pm 8.80$ ) compared to caregivers ( $25.15 \pm 7.54$ ), while caregivers exhibited higher scores in psychological resilience ( $44.68 \pm 12.76$ vs. $41.55 \pm 14.31$ ) and positive coping ( $16.14 \pm 5.73$ vs. $14.45 \pm 7.03$ ).
Correlations: A strong positive correlation existed between patient and caregiver psychological distress ( $r = 0.814, P < 0.001$ ). Resilience and positive coping in both members were negatively correlated with distress in both members ( $P < 0.001$ ).
APIM Findings:
- Resilience Model: Both patient and caregiver resilience showed significant negative actor effects (associated with own distress) and negative partner effects (associated with the other's distress).
- Coping Model: Similar negative actor and partner effects were observed for positive coping. Notably, the partner effect of caregiver positive coping on patient distress ( $B = -0.563$ ) was more pronounced than the reverse ( $B = -0.147$ ).
Dyadic Patterns:
- Patient Resources: Both patient resilience and patient positive coping followed a couple pattern ( $k$ values where 95% CI included 1), indicating that patient psychological resources are associated with distress in both members with similar magnitudes.
- Caregiver Resources: Caregiver resilience and positive coping followed a mixed pattern ( $k$ values where 95% CI included 0.5), indicating that while caregiver resources affect both members, the association with their own distress is stronger than the association with the patient's distress.

Key Contributions

Dyadic Framework Application: The study successfully applied the APIM to the decompensated cirrhosis population, moving beyond single-informant analyses to demonstrate that psychological distress and resources are interdependent within the dyad.
Differentiation of Roles: By distinguishing between actor and partner effects, the study reveals that while patient psychological resources function as a shared "couple" resource, caregiver resources primarily buffer their own distress, with a secondary, though significant, impact on the patient.
Identification of Protective Mechanisms: The findings confirm that resilience and positive coping are not merely individual traits but relational protective factors that mitigate distress for both the patient and the caregiver.

Significance and Claims
The authors claim that these findings support a shift in clinical perspective: psychological distress in decompensated cirrhosis should be understood within a dyadic caregiving framework rather than solely at the individual patient level.

Assessment Implications: The study suggests that nurse-led psychosocial assessments should include both patients and primary caregivers to capture the full scope of psychological risk and resources.
Intervention Implications: The identification of "couple" versus "mixed" patterns informs the design of dyadic interventions. Interventions targeting patient resources may yield synchronous benefits for the dyad, whereas interventions targeting caregiver resources must focus on translating those internal resources into observable support behaviors that patients can perceive and accept.
Modesty of Claims: The authors explicitly state that due to the cross-sectional design, causal directions cannot be inferred. They acknowledge limitations regarding the single-center sample, the lack of covariates (e.g., disease severity, social support) in the unadjusted models, and the reliance on self-report data. Consequently, the study positions its findings as a basis for future longitudinal research and the development of nurse-led, dyadic psychosocial interventions rather than definitive proof of causal mechanisms.
