The aim of this study was translating and adapting the SFLQ to Turkish and evaluating the validity and reliability for adults in Turkey. In accordance with the purpose of the study, a 2-part questionnaire was prepared. The first part focused on the sociodemographic characteristics, including age, sex, and questions that determine food label reading habits. The second part consisted of the Newest Vital Sign (NVS) test, Turkey Health Literacy SCALE-32 (TSOY-32) and Short Food Literacy Questionnaire (SFLQ). The construct validity of the SLFQ was assessed using factor analysis. The Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy was 0.811. Bartlett's test of sphericity was significant (X2=841.958, df=66; p<0.001). A Scree plot and eigenvalues determined that one factor should be retained, which accounted for 32.01% of the variance. The questionnaire factor loadings varied between 0.43 and 0.64. Internal consistency was assessed by calculating Cronbach alfa, and the value was 0.803. There was a positive relationship between SLFQ, TSOY-32 and NVS (r=0.531, p<0.001; r=0.294, p<0.001). As a results of this study, it can be said that SLFQ is a valid and reliable measurement tool, therefore it can be used to describing food literacy among Turkish adults.
