	Vuong Z	AIC Corrected	BIC Corrected	Vuong Z	AIC Corrected	BIC Corrected
Binge Eating	6.03***	5.93***	5.74***	4.22***	3.33***	1.43 (p = .07)
Exercise	10.84***	10.77***	10.64***	5.96***	5.34***	4.05***
Purging	4.84***	4.79***	4.71***	3.47***	2.40**	0.15

Note. Purging includes laxative use and vomiting. Exercise refers to endorsement of driven exercise. Outcome variables measured by the Eating Disorder Examination – Questionnaire (EDE-Q). Stress = Stress related to life events measured by the Daily Stress Inventory. Body Dissatisfaction measured by the EDE-Q. Weight Suppression calculated as the difference between an individual’s highest adult weight and self-reported current weight. NB = negative binomial regression. ZINB Count = count portion of the zero-inflated negative binomial model. ZINB Binomial = Binomial portion of the zero-inflated negative binomial model. Vuong Z = model comparison statistic.
