Abstract The study aimed to translate the Eating-Related Eco-Concern Questionnaire (EREC) into Turkish, ensure its cross-cultural adaptation, and evaluate its reliability, validity, and psychometric properties. EREC is a 10-item scale assessing the extent to which adults consider ecological impact when making food choices due to concerns about climate change. The study was conducted between November 2023 and February 2024 in Mersin with 442 adults aged 18 to 65 years, using face-to-face interviews. The Turkish version was adapted using the Translation–Back Translation method, and language validity was ensured. Face validity was evaluated through a pilot study with 40 participants. Construct validity was initially assessed using exploratory factor analysis (EFA) with data from 200 participants, followed by confirmatory factor analysis (CFA) conducted on an independent sample of 242 participants to verify the factor structure. The reliability of the scale was assessed by test-retest analysis with 106 participants from the main sample (n=442) and consistency was measured by intraclass correlation coefficient (ICC). The factor structure and model fit were evaluated using indices such as CFI, GFI, and RMSEA. 68.3% of the participants were female; whereas, 31.7% were male. The group’s median BMI value was 24.3 (21.6-27.1), with 52.9% classified as “normal” according to the BMI classification. Factor 2 had a low score, but it was found to be adequate for other factors and the total scale score. The Turkish adaptation of the Eating-Related Eco-Concern Questionnaire has been found to be a valid and reliable scale, as confirmed by comprehensive evaluations.
