Psychometric properties of self-monitoring of eating disorder urges among treatment seeking women: ecological momentary assessment using a daily diary method.

Objectives: The psychometric properties of an ecological momentary assessment (EMA) method used to evaluate eating disorder (ED) urges were examined.

Methods: Participants, 139 women who sought treatment for an ED, completed a daily diary measuring ED urges after each meal for a three week period at the start of treatment, and a measure of ED attitudes and behaviors pre- and post-treatment.

Results: The construct validity of this method was indicated by a two factor solution representing binge eating urges and ED compensatory behavior urges, and by significant differences between ED diagnostic groups on ED urge type.
