Growth in externalizing and internalizing problems in childhood: a prospective study of psychopathology across three generations.

Three generations of participants were assessed over approximately 27 years, and intergenerational prediction models of growth in the third generation's (G3) externalizing and internalizing problems across ages 3-9 years were examined. The sample included 103 fathers and mothers (G2), at least 1 parent (G1) for all of the G2 fathers (99 mothers, 72 fathers), and 185 G3 offspring (83 boys, 102 girls) of G2, with prospective data available on the G2 fathers beginning at age 9 years. Behavior of the G2 mother, along with father contact and mother age at birth were included in the models. Intergenerational associations in psychopathology were modest, and much of the transmission occurred via contextual risk within the family of procreation.
