Objectives: To translate the Medication Adherence Scale (MAS) into Chinese and evaluate the psychometric properties of the Chinese version of MAS (C-MAS).
Methods: The study used a cross-sectional design. The performance of C-MAS was assessed among 170 older patients with coronary heart disease (CHD). The psychometric properties of C-MAS, including content validity, factor structure, hypothesized validity, and internal consistency, were tested.
Results: The content validity index of the C-MAS was 0.90. Three factors were identified using the principal component analysis. The Cronbach's α was 0.868 for the total scale and ranged from 0.703 to 0.941 for the three subscales of C-MAS. In addition, the construct validity of the C-MAS was confirmed to test the hypothesis.
Conclusions: The three-factor C-MAS has good validity and internal consistency in older Chinese patients with CHD. The C-MAS can be used to assess the knowledge, attitudes, and barriers related to medication adherence among this population.
