Reliability and validity of Chinese version of the Medication Adherence Self-efficacy Scale

Objective To translate the English version of the Medication Adherence Self-efficacy Scale (MASES) into Chinese and to test the reliability and validity of the Chinese version of MASES in patients with hypertension. Methods Totally 285 patients with hypertension were recruited and were investigated by the Chinese version of MASES. The results underwent analysis for reliability and validity. Results The retest reliability of MASES was 0.843. The Cronbach α of the Chinese version of MASES was 0.876. The Cronbach α of the four dimensions ranged from 0.794 to 0.905. The average content vality index (CVI) of the scale was 0.946. Factor analysis got four factors, which explained 68.683% of the total variance. The factor loading of each item on its common factor was >0.4. Conclusions The Chinese version of MASES has been proved to be reliable and valid. It can be used as a valid tool for the measurement of the patient compliance in patients with hypertension. Key words: Medication Adherence Self-efficacy Scale; Validity; Reliability
