aEffects of teaching intervention (pretest vs. posttest), treatment (live bed bugs vs. picture), and gender (male vs. female) on stigma: self-perception; stigma: social perception; disgust; and psychological distance. The teaching intervention significantly affected stigma related to self-perception (β = −0.027, SE = 0.04) but not stigma related to social perception (not explained by any of the independent variables in the model). The significant effect of the treatment × teaching intervention for disgust (β = 0.11, SE = 0.02) explained that disgust was reduced in the experimental group with live bed bugs but not in the control group with pictures. The significant effect of teaching intervention × gender on psychological distance (β = −0.08, SE = 0.04) indicated that for females, the intervention decreased psychological distance more strongly than for males.
