Validity and reliability of the Turkish version of the Sustainable and Healthy Eating Behaviors Scale

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 eight factors and thirty-four 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 center dot 912, and the intra-class correlation coefficient was found to be good at 0 center dot 832 using the test-retest method. Considering the suitability of the data for factor analysis, the Kaiser-Meier-Olkin coefficient was 0 center dot 859, and the significance level of the Bartlett test of sphericity was less than 0 center dot 05 (chi(2)=3 center dot 803,25; P < 0 center dot 05). As a result of EFA, the items of the scale were found to be distributed in seven factor dimensions. The factor loadings of the items were between 0 center dot 516 and 0 center dot 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 (chi(2)/sd = 2 center dot 593, comparative fit index = 0 center dot 915, Tucker-Lewis index=0 center dot 902, standardised root mean square error = 0 center dot 0754 and root mean square error of approximation = 0 center dot 067). In conclusion, the Turkish version of the SHE Behaviors Scale has credible reliability and construct validity to assess the sustainable and healthy eating behaviours of the Turkish adult population.
