Design outcomes

Primary

MeasureTime frame
Primary outcomes are the possible moderating effects of child genotype on the IY intervention effect (i.e., on the decrease in externalizing problems behavior and/or increase in prosocial behavior of the child). The intervention effect will be assessed with the ECBI, the Matson Evaluation of Social Skills with Youngsters (MESSY), and the Dyadic Parent-Child Interaction Coding System-Revised (DPICS-R).

Secondary

MeasureTime frame
Secondary outcomes will be the observed (changes in) emotional synchronization in parent-child interactions as possible underlying behavioral mechanism to the G×(G)×E interactions.
