Background And ObjectiveTo validate the satisfaction questionnaire Anti-Clot-Treatment Scale (ACTS) in outpatients with nonvalvular atrial fibrillation (NVAF) treated with oral anticoagulants attended in Internal Medicine and Neurology departments in Spain.MethodsIn this cross-sectional and multicentrer study, 1,337 outpatients aged≥18 years, with NVAF, treated with oral anticoagulants≥3 months, attended in Internal Medicine and Neurology departments in Spain were analyzed. The patients completed ACTS, Self-Assessment of Treatment Questionnaire (SAT-Q) and EuroQol-5 dimensions (EQ-5D) questionnaires. ACTS is a satisfaction tool that specifically analyzes burdens (higher score, lesser burden) and benefits (higher score, higher benefit) with anticoagulant treatment. The psychometric properties of the questionnaire were evaluated according to the classical test theory.ResultsThe average time to complete the questionnaire was 8.99±6.06min and 63.70% of patients needed assistance to complete it. There was a high concordance between test and retest scores. Total reliability (Cronbach's alpha) was 0.95 in the ACTS Burdens scale and 0.82 in the ACTS Benefits scale. The factorial model was pertinent. All correlations with the SAT-Q questionnaire were positive, moderate and statistically significant. With regard to the EQ-5D-3L questionnaire, correlations were positive, low and statistically significant. Patient satisfaction was higher in the individuals being treated with new direct oral anticoagulants.ConclusionsIn patients with NVAF treated with oral anticoagulants, the Spanish version of ACTS questionnaire was reliable, valid and feasible.Copyright © 2016 Elsevier España, S.L.U.
