Note: The variance components are raw; they do not sum to 1.00. The proportions of variance sum to 1.00. 95% confidence intervals are given in parentheses. GPA is grade point average; AAB is log-transformed symptoms of DSM Adult Antisocial The variance components and correlations for AAB at each age are given at the mean levels of the moderating variables and at 2 standard deviations above and below their mean levels.
