Description

The Dutch Eating Behavior Questionnaire is an internationally widely used instrument assessing different eating styles that may contribute to weight gain and overweight: emotional eating, external eating, and restraint eating. [...] The German version incorporates two important modifications from the original Dutch and the English versions:

  1. three items from the emotional eating subscale were removed resulting in a total number of 30 items [...],

  2. while the items in the Dutch original and English version were formulated as questions, items in the German version were formulated as statements.
