The association between psychological factors and self-care in patients with heart failure: an integrative review

Aims This integrative review aims to describe the current evidence concerning the relationship between a broad range of psychological factors (depression, depressive symptoms, anxiety, stress, and type-D personality) and self-care in patients with heart failure. Methods and results Six electronic databases were searched and keywords were used to identify potential eligible studies published within the last 10 years. To be eligible, individuals with heart failure aged 18 years or older and who were included in any type of observational study that examined the association between psychological factors and self-care were considered. Twenty articles were included, and 16 of them reported that depression/depressive symptoms were associated with poorer self-care, after controlling for age, sex, education level, cardiac history, or comorbidities. Five studies found that self-care confidence/self-efficacy mediates the relationship between depression/depressive symptoms and self-care. The association between depression/depressive symptoms and self-care varied in assessment methods and statistical approaches. Seven studies showed an inverse association between anxiety and self-care. Four studies found a stronger association between self-care and depression compared with the relationship between self-care and other psychological factors. Stress and type-D personality were both associated with self-care in four studies. Conclusion Depression/depressive symptoms and anxiety were found to be inversely associated with self-care in patients with heart failure. Depression exhibited a stronger impact on self-care than other psychological factors. Limited studies assessed stress and type-D personality; the results should be considered with caution. Further studies are warranted on different psychological factors and their underlying mechanisms in individuals with heart failure.

Automated summary

This integrative review aimed to examine the relationship between psychological factors and self-care in patients with heart failure. The results showed an inverse association between depression/depressive symptoms and self-care, with depression having a stronger impact. Limited studies assessed stress and type-D personality, and further research is needed to explore the underlying mechanisms.
