Abstract
The goal of this chapter is to define some of the basic principles of psychodynamic psychotherapy and to demonstrate how these therapies are useful in helping people recover from co-occurring addictive and trauma related disorders. In distinguishing psychodynamic psychotherapies from other forms of therapy, I will highlight the importance of the context and meaning of trauma, the therapeutic relationship, and the recovery process. After defining trauma and psychodynamic psychotherapy, I will offer an alternative way to conceptualize some commonly seen ego defenses. Effective interventions for assisting clients who present with co-occurring addictive and trauma related disorders will be offered. Lastly, I will point out commonalities between traditional addictions treatment and a model of psychodynamic psychotherapy.
