Eating style: a validation study of the Dutch Eating Behaviour Questionnaire in normal subjects and women with eating disorders.

This study is a validation of the Dutch Eating Behaviour Questionnaire (DEBQ). Results from normal men and women confirmed the presence of three robust factors of restraint, emotional eating and external eating. Data from women attending 'weightwatchers', and patients with diagnoses of anorexia nervosa and bulimia indicated that the DEBQ was largely successful in identifying the eating styles which are thought to characterise these three client groups. The results were also evaluated in the light of predictions from restraint theory which suggest that chronic restraint is causally related to higher levels of externality and emotional eating.
