Systems modeling of behavior change: two illustrations from optimized interventions for improved health outcomes.

Systems science techniques are becoming increasingly important as tools for modeling behavior change and as enablers for delivering more effective tailored interventions [1], [2]. Systems approaches offer a fresh perspective on the understanding of behavior change, providing a means for better capturing complexity, exposing gaps in the existing body of knowledge, enhancing the predictive capability of models, and ultimately enabling optimal decision making in behavioral intervention settings.
