  1. Significant estimates are italic (p < 0.05). Aggression and depression scores were transformed to lower skewness. Time^2 is the quadratic term for time. Age was centered on the grand mean. Sex was binary coded: 0 = female, 1 = male. Group was binary coded: 0 = control group, 1 = clinical group. VAR variance, SD standard deviation, AIC Akaike information criteria, BIC Bayesian information criterion. − 2LL = negative two log likelihood
