There is no question that Sigmund Freud, the founder of the theory that underlies ego psychology, was a genius. Freud used observations to develop his theory in the context of his cultural and religious milieu. Over the years, many have discounted his theory as being sexist, homophobic, and biased toward the more affluent.
Yet, given all of these limitations, what he came up with was the first comprehensive theory to explain human behavior. In addition, he developed a concurrent theory of personality development that was integrated into the theory. To this day, there has not been another psychological approach integrating a personality theory that directly connects to the practice of psychotherapy. It is important to understand the history of ego psychology theory and practice as it still seeps into the current practice of clinical social work. Ego psychology terms are still part of our therapeutic vernacular, such as defense mechanisms, ego strengths, and insight. Even active listening, so commonly used in therapy, has its roots in ego psychology. This chapter gives an overview of ego psychology theory and practice, showing its historical and current influence in the practice of clinical social work.
