Note. N = 575. Belief strength and motivation to comply were measured on a 5-point bipolar scale. n_im_i Ranges from 1 to 25 with higher values indicating supportive referents. Statistics are calculated only if referent was mentioned and participant did not indicate “not applicable.” Values of 3 (neutral midpoint of scales) were imputed for participants who chose “not applicable” in calculations of Σn_im_i.
