Objective:

To examine the actor-partner interdependence mediation effect of family cohesion and adaptability on self-care ability in patients with chronic heart failure (CHF) and their spouses.

Approach:

Key Findings:

• Family function scores for CHF patients and their spouses were 102.36 ± 18.24 and 98.75 ± 16.83, respectively.
• The total score of HFSPS for patients was 52.71 ± 12.38, and for spouses, the EHFScBS-C score was 64.18 ± 14.79.
• The SCHFI total score for patients was 155.73 ± 43.30, with the management dimension being the weakest at 48.67 ± 13.76.
• In subject effect analysis, family function directly influenced self-care ability (38.5%), with symptom perception (35.3%) and care contribution (26.2%) as indirect paths.
• In object effect analysis, the spouse’s family function directly affected the patient’s self-care ability (40.0%), with symptom perception (32.3%) and care contribution (27.7%) as indirect paths.

Interpretation:

Family cohesion and adaptability are associated with lower symptom burden and greater spousal care contributions, linked to improved self-care ability in CHF patients.

Limitations:

• The study used convenience sampling, which may limit generalizability.
• The cross-sectional design does not allow for causal inferences.

Conclusion:

Clinical interventions should consider the patient-spouse dyad as a whole to enhance self-care ability in CHF patients.
