The eating disorder examination questionnaire (EDE-Q) Global score is a self-report measure of global eating disorder (ED) psychopathology. This study used ecological momentary assessment (EMA) to evaluate the ecological validity of EDE-Q Global scores among obese adults. Fifty obese adults completed the EDE-Q and 2 weeks of EMA ratings prior to initiating eating episodes and subsequently after eating episodes. EMA items assessed behavioral symptoms [i.e., loss of control (LOC) eating and overeating] and cognitive symptoms (i.e., weight/shape concerns, eating concerns, and restraint). EDE-Q Global was associated with increased EMA weight/shape concerns and fear of LOC at pre-eating recordings. EDE-Q Global was associated with increased EMA post-episode weight/shape concerns, eating concerns, LOC eating, and overeating. There was no association between EDE-Q Global and EMA restraint. Results generally supported the ecological validity of EDE-Q Global scores. Future studies of ED psychopathology in obese adults may benefit from considering EDE-Q Restraint separately.
