Parallel process latent growth curve mediation models of the impact of ADHD status on social-cognitive problem solving and (a) Prosocial Behavior, and (b) Aggressive Behavior. All covariates (ethnicity, gender, intervention, ODD problems, peer deviancy, school safety problems, parental monitoring) were regressed on all latent LGM slope and intercept variables, and were allowed to correlate with ADHD status (Table 3; not shown in Figures). ADHD to slope and Intercept to slope pathway estimates reflect the total change over middle schools (B-weight*33 months). I=Intercept, S=Slope. ~, p < .10; *, p < .05; **, p < .01
