[Assessment and Therapy of Adolescent Identity Diffusion].

Assessment and Therapy of Adolescent Identity Diffusion Identity diffusion, one of the main diagnosis criteria for borderline personality disorder (BPD), is characterized by a lack of coherent sense of self and of significant others, paired with a painful sense of incoherence. The revision of the age limit for the diagnosis of personality disorders in DSM-5 has opened the doors to research on diagnosis and treatment of BPD in adolescence. This paper offers a summary of past and present work on the diagnosis and therapy of identity disturbance in adolescent patients.
