This study aimed to adapt the Gratitude for Food Scale (GFS) into Turkish and evaluate the psychometric properties of the GFS for adults (GFS-A), considering the need for culturally sensitive and reliable tools. The study was conducted web-based with 421 adults (41.8 % male, 58.2 % female). Translation-back translation method was applied in language validity and pilot test (n = 50) was performed to evaluate the clarity of the items. Then, construct (exploratory factor analysis (EFA; n = 208) and confirmatory factor analysis (CFA; n = 213)) validity and convergent validity were tested. In reliability analysis, Cronbach's α coefficient was calculated for internal consistency and test–retest method was applied. As a result of EFA, factor loadings of items in single factor structure were between 0.729 and 0.893 (variance explained = 68.88 %). According to CFA, fit indices (χ2/sd = 1.866, RMSEA = 0.045, TLI = 0.992, CFI = 0.996, GFI = 0.992, AGFI = 0.975) were acceptable. Average variance extracted (AVE = 0.689) and composite reliability (CR = 0.917) were found to be sufficient for convergent validity. Cronbach's α coefficient (0.856) was highly reliable. According to test-retest analysis, intraclass correlation coefficient was found to be 0.613 (p < 0.01). The Turkish version of GFS-A, with 5 items and one factor, is a valid and reliable tool to measure gratitude for food in Turkish adults.
