Anna Freud defined defense mechanisms as "unconscious resources used by the ego" to decrease internal stress ultimately. Patients often devise these unconscious mechanisms to decrease conflict within themselves, specifically between the superego and id. Psychodynamic therapy is used by clinicians to help orient patients to their own unconscious processes. By recognizing and identifying these processes, patients improve their self-awareness and gain a new understanding of their own behaviors. This activity defines major defense mechanisms to increase clinician's understanding of their patients during patient encounters and the role of the interprofessional team in the care of these patients. Objectives: Identify and define the common psychological defense mechanisms. Describe the goal of psychodynamic therapy in relation to defense mechanisms. Review the clinical significance of defense mechanisms in relation to psychodynamic therapy. Outline interprofessional team strategies for improving coordination and communication in the care of patients with defense mechanisms. Access free multiple choice questions on this topic.

Sigmund Freud, known as the father of psychoanalysis, began the discussion of defense mechanisms in the nineteenth century in relation to the subconscious defenses of the id, ego, and superego.[1] These initial defense mechanisms were more clearly defined and analyzed by his daughter, Anna Freud, in the twentieth century. She created 10 major defense mechanisms, but the number of mechanisms has since been increased by later psychoanalysts.

Recognition and interpersonal communication about any defense mechanisms the patient is using amongst the psychiatrist, psychologist, social worker, primary care provider, nurse, and family can help to orient the team and enhance patient-centered care. Psychodynamic therapy can involve the patient in their own care by achieving greater awareness of their own patterns of psychological defense mechanisms. Some meta-analysis studies have shown psychodynamic therapy to have equal efficacy compared to cognitive behavioral therapy and pharmacotherapy in the treatment of mild to moderate mood disorders. It is important to recognize that therapeutic treatments based on self-awareness and communication will avoid the possible complications of pharmacotherapy, such as side effects and drug-to-drug interactions, and some patients may be more willing to try these therapies compared to pharmacotherapy.[11]
