This study was conducted to determine the validity and reliability of the Turkish version of the Sustainable and Healthy Eating (SHE) Behaviors Scale. The original scale included 8 factors and 34 items related to the SHE behaviors of adults. The research was carried out in three stages with a total of 586 participants aged 19 to 50 years. The Cronbach alpha coefficient was used to evaluate internal consistency reliability and the test-retest method was applied. Exploratory factor analysis (EFA) was performed to determine the factor structure. The model obtained with EFA was evaluated with confirmatory factor analysis (CFA). The Cronbach alpha coefficient of the scale was found to be excellent at 0.912, and the intra-class correlation coefficient was found to be good at 0.832 using the test-retest method. Considering the suitability of the data for factor analysis, the KMO coefficient was 0.859, and the significance level of the Bartlett test of sphericity was less than 0.05 (χ2=3.803,25; p<0.05). As a result of EFA, the items of the scale were found to be distributed in 7 factor dimensions. The factor loadings of the items were between 0.516 and 0.890, and the factors explained 67% of the variance. Considering the fit indices obtained as a result of the analysis of this model with CFA, it was seen that the model had an acceptable fit (χ2/sd=2.593, CFI=0.915, Tucker-Lewis index=0.902, SRMR=0.0754, and RMSEA=0.067). In conclusion, the Turkish version of the SHE Behaviors Scale has credible reliability and construct validity to assess the sustainable and healthy eating behaviors of the Turkish adult population.
