Diagnosing Borderline Personality Disorder During Adolescence: A Review of the Published Literature

Borderline personality disorder (BPD) is a debilitating disorder that occurs in approximately 1% to 3% of the general population. BPD is not only relatively prevalent; it is also associated with significant public health and security concerns. The clinical and social burden of adult BPD diagnosis has resulted in the desire for early diagnosis and the implementation of early intervention programs. A qualitative review of the scientific literature suggested that adolescence is a critical point for the early identification and therapeutic treatment of BPD. Although findings are far from conclusive, the inter-rater reliability and internal consistency of the Diagnostic and Statistical Manual of Mental Disorders symptom criteria for BPD during adolescence seem adequate. Recent studies based on a rigorous methodology of BPD assessment and large community samples reported prevalence rates for BPD diagnosis during adolescence that were less suspect than previous findings. A number of research studies addressed the construct validity of BPD in adolescents (i.e., whether a BPD diagnosis during adolescence actually measures what is intending to measure) and reported consistent relationships between BPD and associated areas of dysfunction and distress as evidence of the validity of the BPD diagnosis. Research evidence indicates that there is no single symptom that is predictive of later BPD diagnosis during adolescence; rather, a pattern of two to three selected BPD symptoms that are evident during adolescence seemed to be highly predictive of later BPD diagnosis, particularly when measures that were specifically designed to assess for BPD during adolescence were used as part of the assessment process.
