Examining trait-like factors as predictors of state-level responses to food intake in women with bulimia nervosa, purging disorder, and controls.

In the present study, individual differences in weight/shape concerns at baseline predicted greater increases in state weight/shape concerns following eating. These effects were maintained when considering possible differences related to presence and type of eating disorder. Results suggest that targeting weight/shape concerns earlier in treatment may be important for reducing maladaptive responses to eating across eating disorders.
