Posttraumatic stress disorder among children clinically diagnosed as borderline personality disorder.

Using the Diagnostic Interview for Children and Adolescents, Revised Version (DICA-C-R), the authors evaluated 19 children ages 7 to 14 who had recently been clinically diagnosed as borderline personality disorder by DSM-III-R criteria. The results reveal that 78.9% of these children reported significant traumatic experiences, with 36.8% fitting DICA-C-R criteria for posttraumatic stress disorder. These findings raise the possibility that a diagnosis of borderline personality in childhood can often represent posttraumatic stress disorder.
