The purpose of this paper is to develop a preliminary comprehensive model of antisocial development based on dynamic systems principles. The model is built on the foundations of behavioral research on coercion theory. First, we focus on the principles of multistability, feedback and nonlinear causality to reconceptualize real-time parent-child and peer processes. Second, we model the mechanisms by which these real-time processes give rise to negative developmental outcomes that, in turn, feed back to determine real-time interactions. Third, we examine mechanisms of change and stability in early- and late-onset antisocial trajectories. Finally, novel clinical designs and predictions are introduced. Throughout, we highlight new predictions and present recent studies that have tested aspects of the model.
