The impact of meal consumption on emotion among individuals with eating disorders.
OBJECTIVE
This pilot study sought to determine how meal consumption impacts affective states for treatment-seeking individuals with eating disorders (ED).


METHODS
Participants with heterogeneous ED diagnoses completed the State-Trait Anxiety Inventory, Positive and Negative Affect Schedule, and Profile of Mood States measures before and immediately after meal consumption.


RESULTS
Meal consumption was associated with significant decreases in negative affect and total mood disturbance for individuals with binge eating disorder (BED). Decreases in negative affect across meal time for individuals with BED were significantly different from increases in negative affect for participants with anorexia nervosa (AN) and bulimia nervosa (BN).


CONCLUSIONS
Findings indicate that individuals with BED have significantly different affective responses to eating non-binge meals than individuals with AN or BN. Data suggest changes in negative affect following meal consumption may be specific to certain ED diagnoses. Results provide preliminary evidence consistent with the idea that emotion states may function as maintenance mechanisms for psychopathology among ED diagnoses. Limitations and future directions pertaining to food-mood relationships for individuals with ED are discussed.
