Background
Depression prevalence in patients with heart failure (HF) is 21% to 42%. Conceptual
illness beliefs that patients have about HF may be associated with depression.
Methods
We examined whether accuracy of illness beliefs was associated with depression. Illness
belief scores were compared with depression severity, and multivariable analyses were
performed to determine factors that were independently associated with depression.
Results
In 219 elderly patients with HF, depression prevalence was 47%. Accuracy of illness
beliefs was associated with depression (r = .224; P = .049), due solely to accuracy of beliefs about consequences of HF (P = .005). Beliefs about how to control HF remained stable as depression severity increased.
After controlling for significant univariable factors, mean illness belief and consequence
scores remained associated with depression.
Conclusion
In this sample, accuracy of beliefs about HF consequences increased but beliefs about
how to control HF remained unchanged as depression severity worsened. This combination
of HF beliefs may influence coping through self-care behaviors.
