Abstract: INTRODUCTION:The aim of study was to assess the reliability and validity of the14-point Mediterranean Diet Adherence Screener (MEDAS) among Iranian high risk population. METHODS:Study was conducted in north of Iran a country with a Shiite majority with religious constraints, so we modified the MEDAS in the Farsi version. We applied reliability analysis using the Kuder – Richardson 20 and the alpha coefficient of Cronbach, with SPSS to interpret the effects of each item of MEDAS in its internal consistency. RESULTS:After correcting the item scores, coefficients of Kuder-Richardson-20 was calculated 0.559. The mean±SD of 13 items MEDAS was 5.73±1.88. None of Corrected Item-Total Correlation coefficients were negative. 43%, 53% and 4% participants had low, medium and high adherence to a Mediterranean diet respectively. CONCLUSION:In spite of making a few changes in questions, the coefficients of Kuder-Richardson-20 did not decrease in reliability analysis. The MEDAS was translated for the first time into Farsi. Administering this tool in future researches will help to understand how Iranian adhere to the mediterranean diet, aiming at improving cardiovascular health.
