Figure 1.

Plots of hypothetical trajectories for two mother-child dyads where mother’s depression affects the child’s externalizing behaviors. In both figures the change in child’s behavior (solid gray line) is coupled to the change in mother’s depression (solid black line). The figures differ in the initial trajectories of the children (dashed gray lines). Panel A shows a relation where the scores of the mother and child would be highly correlated. In Panel B, whereas the mother’s depression is leading to changes in the child’s trajectory from his/her initial trajectory, the scores of the mother and child would have a correlation near zero.
