An experiment was conducted to see how people with eating disorders differ in their need to exert control in different domains. Participants were classified as not having an eating disorder (control), as having anorexia nervosa (anorexic), or as having bulimia nervosa (bulimic). Each participant underwent an experiment that indicated how much they felt the need to exert control in three domains: eating, friendships and the physical world (this final category was a control domain in which the need to have control over things like gravity or the weather was assessed). So all participants gave three responses in the form of a mean reaction time; a low reaction time meant that the person did feel the need to exert control in that domain. The variables have been labelled as group (control,

anorexic, or bulimic) and domain (food, friends, or physical laws). Looking at the output below, what can we conclude about the main effect of the domain variable?





A. People with eating disorders need to exert more control over different domains of their life compared to controls, F(1.55, 41.89) = 8.02, p < .01.

B. There was a significant effect of domain, F(1.55, 41.89) = 8.02, p = .001, on the degree to which people felt the need to exert control.

C. There was a significant effect of domain, F(2, 54) = 8.02, p < .01, on the degree to which people felt the need to exert control.

D. There was not a significant effect of domain, F(2, 54) = 8.02, p < .05, on the degree to which people felt the need to exert control.
