This training will provide an overview of attachment theory and infant mental health to help explain why teenagers behave the way they do.  The importance of having healthy early childhood relationships and meeting key developmental tasks is essential in ensuring individuals learn healthy coping skills and create positive relationships throughout their life. But what happens when this is not attainable? In addition, when we consider normative brain development versus trauma affected brain development, we can further hold the framework for understanding adolescent behavior and emotions. By taking a relational and trauma lens, participants will deepen their understanding of the root causes of oppositional, risky, antisocial, or even aggressive behavior.  Interventions that are individualized, and based on providing corrective relational experiences are the key to helping teenagers learn better coping, safer decision making, and overall increase future success.
