Abstract
In this study, the authors investigated whether self-reported physical functioning of patients with chronic obstructive pulmonary disease (COPD) and chronic systolic heart failure (CHF) was primarily explained by illness-specific differences related to diagnosis or whether more generic factors also contributed to their physical functioning. Consecutive patients with COPD (n = 56; mean age = 67.8, SD = 8.5) and CHF (n = 65; mean age = 60.0, SD = 10.2) from the outpatient clinics of a university hospital and a general hospital completed a self-report questionnaire, including the Rand-36 Health Survey, Cantril's ladder the Mastery scale, the Perceived Health Competence Scale, and the Self-efficacy scale. COPD patients scored significantly worse in self-reported physical and psychological functioning and perceived health competence than did patients with CHF. Regression analysis revealed that both the diagnosis and the illness severity contributed to self-reported physical functioning, although self-efficacy ...
