Abstract
ObjectiveThe Mediterranean Lifestyle Index (MEDLIFE) differs from similar scales in that it concurrently includes diet and lifestyle. The current study translated MEDLIFE into Turkish, and assessed its reliability and validity. MethodsA questionnaire was administered to 300 individuals 19–65 years of age. The questionnaire was subsequently re-administered to 87 research participants. The questionnaire, asking for general information, MEDLIFE, and information regarding anthropometric measurements, was sent to the users of an online platform. The scale was converted into the applicable Turkish form by an expert group. Test-retest reliability was evaluated with the intraclass correlation coefficient (ICC). In addition, kappa coefficients (k) and Bland–Altman graphs were determined for each item to assess reliability. ResultsThe mean scores before and after were 14.5 ± 3.68 and 14.3 ± 3.81, respectively, and the intercorrelation coefficient r was 0.817 for test-re-test reliability. ConclusionThe validity and reliability of the scale in the Turkish language was confirmed. This study is the first to translate MEDLIFE into another language and may aid in assessing the scale's adaptability to other languages. Food consumption record and physical activity record studies must be performed to ensure validity.
