Özet

This paper established the Turkish validity and reliability of the Reward-based Eating Drive Scale (RED-13). This methodological study was conducted between January and June 2022. The study population consisted of all patients admitted to the dietary polyclinic of a hospital. The sample consisted of 500 participants. Data were collected using a personal information form and the Reward-Based Eating Drive Scale (RED-13). The data were analyzed using numbers, percentages, arithmetic means, standard deviations, correlation tests, t-tests, exploratory and confirmatory factor analyses, and Cronbach’s α reliability coefficients. The scale consists of 13 items and three subscales, explaining 66.1% of the total variance. The confirmatory factor analysis shows that x²/sd= 2.47, indicating an acceptable model. The goodness of fit indices are also acceptable (GFI = 0.99, AGFI = 0.99, CFI= 1.00, RMSEA = 0.08, and SRMR = 0.05). The total scale has a Cronbach’s α of 0.91. The first and second halves have Cronbach’s α values of 0.86 and 0.83, respectively. The scale has a Spearman-Brown coefficient of 0.85 and a Guttman Split-Half coefficient of 0.83. The scale has good internal consistency (reliability). The results indicate that the Reward-Based Eating Drive Scale (RED-13) is valid and reliable for the Turkish population.
