摘要：Background: Patients with heart failure (HF) experience difficulty performing activities of daily living. As impaired functional status is adversely associated with outcomes, it is important to accurately evaluate patient functional status. The Duke Activity Status Index (DASI) is a 12-item, self-administered questionnaire to measure functional status. However, its psychometric properties have not been determined in patients with HF. The purpose of this study was to examine the psychometric properties of the DASI in patients with HF.
