Note. Initial analyses controlled for the effect of the other hormone (i.e., progesterone in correlations between estradiol and disordered eating, estradiol in correlations between progesterone and disordered eating). Partial analyses controlled for the effect of the other hormone, negative affect, and emotional eating. EDI = Eating Disorder Inventory. TFEQ = Three Factor Eating Questionnaire.
