A. The body shape questionnaire correlated with neural responses in the Self – Friend cluster from the adult study. Adolescents that scored high on the body shape questionnaire, both AN-A and HC-A, had more activation of the MPFC-dACC cluster when considering their friend than when considering themselves. Regression lines for AN-A (dashed black, r = -0.46, p = 0.02), HC-A (dashed gray, r = -0.43, p = 0.08), and the entire group (solid, r = -0.44, p = 0.004) are shown. B. Participants in the AN-A group reporting higher levels of anxiety activated the MPFC-Cing cluster more when disagreeing with statements about themselves than when agreeing with statements. Regression lines for AN-A (dashed black, r = -0.51, p = 0.01), HC-A (dashed gray, r = -0.51, p = 0.03), and the entire group (solid, r = -0.37, p = 0.13) are shown.
