The role of identity in the DSM-5 classification of personality disorders.

In the revised Diagnostic and Statistical Manual DSM-5 the definition of personality disorder diagnoses has not been changed from that in the DSM-IV-TR.

The differentiation between an identity crisis, a transient phenomenon that usually results (after resolution) in a well-integrated identity with flexible and adaptive functioning, and an identity diffusion that is viewed as a basis for subsequent personality pathology, has a major impact on the selection of a treatment method.

[Treatment of adolescents with identity diffusion: a modification of transference focused psychotherapy].

This paper is an introduction to a treatment for adolescents with identity diffusion that has been modified from a therapy that has been found to be effective in the treatment of adults with significant identity diffusion, namely, Transference Focused Psychotherapy. The central role of differentiating normal Identity Crisis from Identity Diffusion in adolescents, essential to accurately identifying those adolescents appropriate for this treatment, is articulated. The primary modifications of TFP for adolescent treatment described involve changes in frequency and duration of some of the specific techniques (e.
