Validity varied extensively and there was a widespread lack of information regarding measurement of change over time and patient burden .
According to the evaluation criteria , there was adequate support for two tools .
The present study aims to identify the range of  eating behavior self- assessment tools reported in the adult bariatric surgery literature and evaluate the measurement properties of these tools using pre-established criteria .
Preliminary validation of the Yale Food Addiction Scale
Previous research has found similarities between addiction to psychoactive substances and excessive food consumption . Further exploration is needed to evaluate the concept of " food addiction , " as there is currently a lack of psychometrically vali date d measurement tools in this area . The current study represents a preliminary exploration of the Yale Food Addiction Scale ( YFAS ) , design ed to identify those exhibiting signs of addiction towards certain types of foods ( e.g. , high fat and high sugar ) . Survey data were collected from 353 respondents from a stratified r and om sample of young adults . In addition to the YFAS , the survey assessed eating pathology , alcohol consumption and other health behaviors . The YFAS exhibited adequate internal reliability , and showed good convergent validity with measures of similar constructs and good discriminant validity relative to related but dissimilar constructs . Additionally , the YFAS predicted binge-eating behavior above and beyond existing measures of eating pathology , demonstrating incremental validity . The YFAS is a sound tool for identifying eating patterns that are similar to behaviors seen in classic areas of addiction . Further evaluation of the scale is needed , especially due to a low response rate of 24.5 % and a non- clinical sample , but confirmation of the reliability and validity of the scale has the potential to facilitate empirical research on the concept of " food addiction "
