State and trait food craving in people with bulimic eating disorders

In two studies, we examined trait and state food craving levels in people with a bulimic disorder (BD) (bulimia nervosa and related disorders) and healthy controls (HC) using multidimensional self-report assessments. In study 1, trait food craving was assessed in 70 people with a BD and 69 HC using the Food Craving Questionnaire — Trait. Participants also completed the Eating Disorder Examination — Questionnaire (EDE-Q). In study 2, 45 people with a BD and 29 HC completed the Food Craving Questionnaire — State and the EDE-Q following exposure to visual and real high-caloric food cues. The results showed that both trait and state food cravings were significantly higher in people with a BD, compared to HC. Trait food craving was associated with eating disorder symptomatology in both the HC and BD groups. State food craving was associated with eating disorder psychopathology, but only in the BD group. This research underscores the importance of food craving in the study and conceptualization of BD.

► Food craving is a prominent trait in people with bulimic eating disorders.
► The presence of food results in high state craving in people with bulimic disorders.
► Craving levels are associated with eating disorder psychopathology.
► Food craving should be incorporated in models for bulimic disorders.
