Abstract
BackgroundYale Food Addiction Scale (YFAS) was established to identify individuals exhibiting signs of addiction towards certain types of food. This study aimed to develop a Turkish version of the Yale Food Addiction Scale and test its psychometric properties.MethodsThe backward translation techniques were used to develop Turkish versions of the YFAS, and its reproducibility was assessed. Turkish version of the YFAS was administered to a total of 1033 participants (439 men and 594 women), aged 19–65 years. Exploratory factor analysis and confirmatory factor analysis were used to examine the factorial structure of the tool. Construct validity was assessed by principal component factor analysis with varimax rotation. Reliabilities were estimated with Cronbach’s alpha coefficient. The criterion-related validity was tested by the administration of Eating Attitude Test-26 (EAT-26) to all participants.ResultsThe primary factor loadings for seven items were ranged between 0.45 and 0.79, and no items cross-loaded onto other factors. The fit indices showed that eight items of the YFAS were a good representation of the item responses and each item loaded significantly on the specified factor (p < 0.001 for each). YFAS subscales had a high internal consistency and test–retest reliability. The criterion-related validity of the tool showed a positive relationship with scales of the EAT-26.ConclusionCurrent study suggested that the Turkish version of the YFAS is a reliable, valid, and useful tool for assessing the signs of food addiction in a non-clinical sample.

Criterion-related validity The Pearson product-moment correlation coefficients were calculated for the YFAS scores and Eating Attitude Test-26 (EAT-26) scores for all participants to test criterion reliability (n = 1033)
The chi-square distribution of participants with normal/abnormal eating behaviors diagnosed by EAT-26 and food addiction/none-food addiction is given at Table 3
Summary
Yale Food Addiction Scale (YFAS) was established to identify individuals exhibiting signs of addiction towards certain types of food. This study aimed to develop a Turkish version of the Yale Food Addiction Scale and test its psychometric properties. The determinative effect of environmental factors such as eating habits and nutrition on the development of obesity has been well established [3,4,5]. A biological basis for food addiction has been shown in several studies [16,17,18]. These studies revealed that food addiction mechanisms exhibited pathways similar to those seen in drug addiction [19]. Hedonic nutrition, which can be described as consumption of food
