Structure of genetic and environmental risk factors for symptoms of DSM-IV borderline personality disorder.

ABSTRACT:

Importance

Previous studies have indicated that the psychopathological dimensions of borderline personality disorder (BPD) are influenced by a unitary liability factor. However, to our knowledge, the underlying etiological nature of the individual criteria for BPD as defined by the DSM-IV has not been explored.

Design, setting, and participants

Multivariate twin study with BPD criteria assessed by personal interview within a general community setting. Participants included 2794 young adults from the Norwegian Institute of Public Health Twin Panel.

Main outcomes and measures

The 9 criteria for BPD assessed by the Structured Interview for DSM-IV Personality.
