Abstract
Purpose
The purpose of this paper is to develop and validate the Greek version of the Mediterranean Diet Adherence Screener (MEDAS).
Design/methodology/approach
The MEDAS was translated to the Greek language forward and backward, twice and subsequently was administered to 50 healthy adult participants living in Attica, Greece. The participants had to complete the tool twice, within a period of 15 days. Participants also completed the well-recognized Mediterranean Diet Score (MedDietScore), for comparison purposes with the tested tool. Socioeconomic and anthropometric characteristics were also assessed.
Findings
There was a moderate association between the Greek MEDAS (MEDAS-Gr) and the MedDietScore [(Pearson r = 0.50, p < 0.001; Intraclass Correlation Coefficient (ICC)=0.46, p = 0.015)]. The concordance between these two questionnaires varied between the items (Intraclass correlation coefficient of 0.62 for fruit at the highest and −0.09 for alcohol consumption). The Cronbach’s a coefficient of reliability for the Greek MEDAS was good (a = 0.62). The two administrations of the MEDAS-Gr produced similar mean total scores (7.6 vs 7.9, p = 0.090), which were correlated (r = 0.71, p < 0.001; ICC = 0.85, p < 0.001) and agreed substantially [k statistic (k)=0.72, 95% CI 0.54–0.89, p < 0.001)].
Originality/value
The MEDAS-Gr seems to be a valid tool for assessing adherence to the Mediterranean diet in the Greek population.
