Current measures of disordered eating are either very narrow in scope (e.g., assess only one aspect of disordered eating, such as disinhibited eating) or have serious limitations, like gender biases, inconsistent factor structures and poor discriminant validity. To address this problem, we developed the EPSI (Eating Pathology Symptoms Inventory; pronounced 'ep-see') measure, which has demonstrated strong evidence for test-retest reliability, internal consistency, and convergent/discriminant validity.
The measure has been tested in over 2,000 subjects and results have been very promising. For example, the EPSI has less gender and weight category bias, a more replicable factor structure, and stronger criterion validity for distinguishing among individuals with different types of eating disorders compared to other established measures of eating pathology.
In the future, we would like to validate the Excessive Exercise, Restricting and Binge Eating cales with the 24-HR (an online dietary recall measure) and a wearable device to track energy expenditure.
