The term narcissism is often pejorative and associated with the diagnosis of narcissistic personality disorder. However, some degree of narcissism can be viewed as essential when considering the ingredients of a healthy personality. The ego state literature contains references to the maturation of ego states, the creation of helpful ego states, transformation of the function of ego states, and the strengthening of healthy ego states as components of the development of a "harmonious family of self." For an individual to develop healthy narcissism and eventually self-esteem, it's assumed that these ego state interventions are involved and produce changes in internal psychic structure. This article explores theories and therapy regarding the development of healthy narcissism, self-esteem, and a well-functioning sense of entitlement. Case material is summarized to illustrate how ego state therapy can be an important part of this process.
