Abstract/OtherAbstract:
Converging research suggests phenomenological and neurobiological similarities between excessive food consumption and addictive behaviour in substance dependence. Recently, the Yale Food Addiction Scale (YFAS) has been proposed for the assessment of addictive eating behaviour. The German version of the YFAS was administered to obese individuals seeking bariatric surgery (N = 96). Factor structure, internal consistency, and item statistics were analysed. Forty participants (41.70%) received a food addiction diagnosis. The one-factorial structure of the YFAS, which has been found in non-clinical samples, could be confirmed. All but three items had factor loadings >.50. Internal consistency was α = .82. Item analysis revealed that items related to unsuccessful attempts to cut down and consumption despite physical and emotional problems were endorsed by the majority of participants. Findings support the use of the YFAS in clinical populations, while applicability of some items differs between clinical and non-clinical samples.
