Borderline personality disorder features and utilization of treatment over two years.

This study assessed the relationship between borderline personality disorder (BPD) features and treatment utilization over a 2-year time period. Participants included 349 18-year-old nonclinical young adults, approximately one-half of whom endorsed significant borderline features. The laboratory phase of the study involved the administration of self-report and interview-based assessments of BPD psychopathology at Wave 1, as well as interviews targeting Axis I psychopathology and treatment utilization history at Wave 2 (2 years later). Results indicated that borderline features prospectively predicted utilization of psychopharmacological treatment above and beyond what was accounted for by gender, lifetime Axis I psychopathology, and nonBPD Axis II psychopathology. The borderline feature most strongly associated with treatment. utilization was affective instability.
