a Best fitting model for genetic and environmental influences on three ODD dimensions and inattention. A, additive genetic influences; C, shared environmental influences; E, nonshared environmental influences; IN, inattention; Genl, general factor; Irr, irritability factor; Def, defiant behavior factor. Path coefficients for the genetic and environmental influences on the ODD factors and on inattention are squared standardized regression coefficients (i.e., variance components) with their 95% confidence intervals shown underneath. Decimal points are omitted to save space. b Best fitting model for genetic and environmental influences on three ODD dimensions and hyperactivity−impulsivity. A, additive genetic influences; C, shared environmental influences; E, nonshared environmental influences; HI, hyperactivity−impulsivity; Genl, general factor; Irr, irritability factor; Def, defiant behavior factor. Path coefficients for the genetic and environmental influences on the ODD factors and on hyperactivity−impulsivity are squared standardized regression coefficients (i.e., variance components) with their 95% confidence intervals shown underneath. Decimal points are omitted to save space. c Best fitting model for genetic and environmental influences on 3 ODD dimensions and CD. A, additive genetic influences; C, shared environmental influences; E, nonshared environmental influences; CD, conduct disorder; Genl, general factor, Irr, irritability factor, Def, defiant behavior factor. Path coefficients for the genetic and environmental influences on the ODD factors and on CD are squared standardized regression coefficients (i.e., variance components) with their 95% confidence intervals shown underneath. Decimal points are omitted to save space. d Best fitting model for genetic and environmental influences on three ODD dimensions and depression. A, additive genetic influences; C, shared environmental influences; E, nonshared environmental influences; Dep, depression; Genl, general factor; Irr, irritability factor; Def, defiant behavior factor. Path coefficients for the genetic and environmental influences on the ODD factors and on depression are squared standardized regression coefficients (i.e., variance components) with their 95% confidence intervals shown underneath. Decimal points are omitted to save space. e Best fitting model for genetic and environmental influences on three ODD dimensions and GAD. A, additive genetic influences; C, shared environmental influences; E, nonshared environmental influences; GAD, generalized anxiety disorder; Genl, general factor; Irr, irritability factor; Def, defiant behavior factor. Path coefficients for the genetic and environmental influences on the ODD factors and on GAD are squared standardized regression coefficients (i.e., variance components) with their 95% confidence intervals shown underneath. Decimal points are omitted to save space. Dashed lines indicate paths that are not significantly greater than 0
