Background and Purpose: Cultural adaptation of Medication Adherence Self-Efficacy Scale-Revised is lacking in the Arab population. This study tested the psychometric properties of the Arabic version of the Medication Adherence Self-Efficacy Scale-Revised. Methods: The study included 199 Omani hypertensive patients. The scale was translated into Arabic. Reliability and construct and convergent validity were examined. Results: Scale’s reliability was α =.93. One factor was identified and explained about 57.5% of the variance. A new modified model with covariance suggested a better model fit. A significant relationship between the scale and Morisky medication adherence scale was found (r =.53, p <.001). Conclusions: The Arabic version scale is reliable, valid, and could be applied in the clinical settings to improve medication adherence.
