Abstract

Aim. The aim of this study was to evaluate the internal reliability and validity of the Brazilian–Portuguese version of Duke Anticoagulation Satisfaction Scale (DASS) among cardiovascular patients. Background. Oral anticoagulation is widely used to prevent and treat thromboembolic events in several conditions, especially in cardiovascular diseases; however, this therapy can induce dissatisfaction and reduce the quality of life. Design. Methodological and cross‐sectional research design. Methods. The cultural adaptation of the DASS included the translation and back‐translation, discussions with healthcare professionals and patients to ensure conceptual equivalence, semantic evaluation and instrument pretest. The Brazilian–Portuguese version of the DASS was tested among subjects followed in a university hospital anticoagulation outpatient clinic. The psychometric properties were assessed by construct validity (convergent, known groups and dimensionality) and internal consistency/reliability (Cronbach’s alpha). Results. A total of 180 subjects under oral anticoagulation formed the baseline validation population. DASS total score and SF‐36 domain correlations were moderate for General health (r = −0·47, p
