Examining the Turkish Validity and Reliability of the Sustainable Food Choice Questionnaire in University Students: A Methodological Study

Objective: This study aimed to determine the validity and reliability of the Turkish version of the Sustainable Food Choice Questionnaire (SUS-FCQ) among university students. Material and Methods: The validity and reliability of the Turkish SUS-FCQ scale were tested. This study was conducted with 439 Turkish university students. Confirmatory factor analysis (CFA), fit indices, and descriptive statistics were used to evaluate the data. The study used the most commonly used fit indices, χ²/df, Incremental Fit Index, Comparative Fit Index, root mean square error of approximation, and standardized root mean square residual, to assess the model-data fit. The reliability coefficient of the scale was evaluated as having reliability above 0.60, between 0.61-0.80 as having an acceptable medium level of reliability, and between 0.81-1.00 as having a very high level of reliability. Results: Cronbach's alpha coefficient of the scale was determined to be 0.976 (excellent). According to the CFA findings, all scale items were statistically significantly grouped under 2 dimensions (p
