Rationale: This study aims to translate the 'Diet Information Overload' scale, which was developed and validated to assess individuals' perceptions of the dietary information environment, into Turkish and to ensure its cross-cultural adaptation.

Methods: The survey was conducted between November 2023 and June 2024 with 464 voluntary participants aged ≥18 and above in Kayseri. Data were collected via face-to-face interviews. For test–retest reliability, the scale was reapplied to 150 participants after two weeks. Language validity was ensured using the translation–back translation method. Reliability was assessed using ICC and Cronbach’s alpha. Content validity (CVI and CVR) was 1 based on the Davis technique. Construct validity was evaluated using confirmatory factor analysis for three models.

Results: All path coefficients obtained from confirmatory factor analysis (CFA) were statistically significant (p<0.001). When looking at the goodness of fit index (GFI), comparative fit index (CFI), Tucker-Lewis index (TLI), and normed fit index (NFI), it was determined that the statistics were greater than 95%. The root mean square error of approximation (RMSEA) and standardized root mean square residual (SRMR) values (<5%) indicated good fit, confirming model validity. The ICC was adequate for all models (>0.70).  Internal consistency was acceptable for Model 1 (α=0.748) and Model 2 (α=0.722), while Model 3 showed lower reliability (α=0.643) due to fewer items.

Conclusion: These findings indicate high internal consistency and overall integrity of the scale. The analyses yielded statistically significant results consistent with the original version. The Turkish adaptation of the Dietary Information Load Scale is a valid and reliable tool and can be used as a practical measure to assess individuals’ perceptions of the dietary information environment.
