Marcia and erikson: The relationships among ego identity status, neuroticism, dogmatism, and purpose in life.

Implicit in James Marcia's writings and in the many studies that have employed his measure of ego identity is the assumption that his four ego identity statuses are developmentally ordered along a continuum from "being identity diffused" to "achieving" an ego identity. In order to assess the validity of this assumption, hypotheses were generated and tested concerning the relationship between the above ordering and Erikson's writings regarding the role played in the process of identity formation by the following three variables: neuroticism, dogmatism, and a sense of purpose in life. If one assumes that Erikson's perspective is valid, then the results of this study fail to support Marcia's continuum assumption. While some of the identity statuses appear to classify persons in a manner consistent with Erikson's writings, not one instance of the postulated ordering of Marcia's four statuses is observed. It is concluded that Marcia's measure is not an adequate operationalization of Erikson's perspective on identity formation.
