Results showedthattwo factors were generated, indicating two statistically distinct ways of responding. Participants who loaded on factor A were characterized by their structured approach around decision-making, thinking through consequences of actions, and tendency towards planning/organization. In all but one participant, this factor was represented by participants with no history of bulimia nervosa. Participants who loaded on factor B were characterized by pleasure-seeking urges, quick action, lack ofself-control, and difficulty in postponing reward.
