Abstract: Objective  AntiClot Treatment Scale (ACTS) is an effective tool to evaluate patients' satisfaction with anticoagulant treatment. The scale is divided into two dimensions: burden and benefit.  The reliability and validity of the Chinese version of ACTS were evaluated. Methods  ACTS were tested for atrial fibrillation patients that had been on oral anticoagulants (OACs) therapy for more than 4 weeks by multistage sampling method. The reliability and validity of the scale were evaluated by structure validity,  internal consistency and testretest reliability. Results  ACTS data were collected in 1 379  patients. Four common factors were extracted by principal component analysis,  and the total　cumulative variance contribution rate of common factors was 67.164%. Internal consistency analysis showed that Cronbach's coefficient  α  of  ACTS  Burdens scale (13 items) and Benefits scale (4 items) were 0.823 and 0.968,  respectively. The testretest reliability analysis suggested that the intergroup correlation coefficients for ACTS Burdens and Benefits were 0.783 and 0.674,  respectively (P<0.01). Conclusion  Chinese version of ACTS has good validity and reliability,  providing a scientific assessment tool for patientreported treatment satisfaction with OACs in selftest.
