Does food use disorder exist? Item response theory analyses of a food use disorder adapted from the DSM-5 substance use disorder criteria in a treatment seeking clinical sample.

This study reports, for the first time, the validity of a potential Food Use Disorder (derived from the 11 DSM-5 SUD criteria adapted to food) in a sample of treatment seeking adults. This has great implications both at the clinical level and in terms of public health policy in the context of the global obesity epidemic.
