Psychometric Properties of the Arabic Version of Medication Adherence Self-Efficacy Scale-Revised in Hypertension

Research output: Contribution to journalArticlepeer-review


BACKGROUND AND PURPOSE: Cultural adaptation of Medication Adherence Self-Efficacy Scale-Revised is lacking in the Arabs 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.
