The Mediator Role of Meaning in Life in the Life Quality of Patients With Chronic Heart Failure
Abstract
Summary: Purpose: Heart failure (HF) is a highly recurrent disease with a high sudden death rate and a substantial influence on disease-related quality of life (QOL). Social support, symptom distress, care needs, and meaning in life all have significant impacts on QOL. We hypothesized that meaning in life plays a mediating role in the relationship of social support, symptom distress, and care needs with QOL among patients with chronic HF. Methods: Based on cross-sectional analysis, we recruited 186 HF outpatients who completed structured questionnaires for social support, symptom distress, care needs, meaning in life, and QOL. Structural equation modeling was used to analyze the mediating role of meaning in life in the relationship of social support, symptom distress, and care needs with QOL. Results: The final model showed good model fit. Meaning in life was associated with global QOL (β = 0.18, p = .032). Although symptom distress (β = −0.26, p = .005) and care needs (β = −0.36, p = .021) were negatively associated with global QOL, meaning in life played a partial mediating role between symptom distress and global QOL (β = −0.02, p = .023) and between care needs and global QOL (β = −0.07, p = .030). However, meaning in life played a complete mediating role between social support and global QOL (β = 0.08, p = .047). The model showed that meaning in life, symptom distress, and care needs explained 50% of global QOL. Conclusions: In patients with chronic HF, meaning in life played a mediating role in the relationship of social support, symptom distress, and care needs with QOL. Implementing an intervention to enrich meaning in life may help patients manage the issues caused by symptoms and alleviate their unmet needs.
