Figure 1. Cortisol reactivity mediates the association between PDE status and behavioral problems.

Figure 1

Note: Unadjusted mediation analyses without covariates; * indicates 0.05<=p<0.10, **indicates p<0.05; The 95% bootstrap confidence intervals for the indirect effect are 0.04-4.28 for aggression scores, 0.03-4.50 for externalizing problems scores and 0.001-0.54 for drug experimentation. Probit regression for the mediator (cortisol reactivity) and weighted least squares estimation were used for all the models. Probit regression was also conducted for the categorical dependent variable (drug experimentation).
