A, additive genetic effects; C, shared environmental effects; E, non-shared environmental effects.

D, parental death; S, parental separation.

CI, confidence intervals; MD, major epression; GAD, generalized anxiety disorder.

INT, internalizing disorders including MD, GAD, phobia, and panic disorder.

EXT, externalizing disorders including alcohhol dependence and drug abuse/dependence.

The values for age are not shown because it accounted for less than 0.1% of the variance.
