Mediation of the association between ACC responsiveness and DBD subgroup membership by YPI II traits. Significant mediation of the association between neural responses in the ACC during fear condition and DBD subgroup membership, i.e. [(DBD-p and DBD-d) vs HC], by YPI II traits was ascertained by bootstrapping. Paths represent associations between (a) IV and M, (b) M and DV, (c) total effect of IV on DV, (c′) direct effect of IV on DV, i.e. correcting for M. ACC, anterior cingulate cortex; YPI, Youth Psychopathic Traits Inventory; IV, independent variable; M, mediator; DV, dependent variable.
