The present study had several strengths. First, the measurement of externalizing problems was theoretically- and empirically-based on developmentally-relevant constructs. Second, it incorporated measurement of externalizing problems from multiple sources to reduce source bias. Third, it described and predicted developmental profiles from childhood to adulthood with numerous measurement occasions. Fourth, it considered many different domains of risk and developmental time frames. Finally, it applied its predictions to illegal behavior in order to demonstrate the robustness of the model’s predictive utility.
