Dramatic-Erratic Personality Disorder Symptoms: I. Continuity from Early Adolescence into Adulthood

Abstract

This longitudinal study examined dramatic-erratic personality disorder symptoms (histrionic, borderline, and narcissistic symptoms) in a community sample of 407 adolescents to assess whether this diagnostic construct is meaningful in young people. Based on latent variable models and dimensional symptom scales, these so-called Cluster B symptoms were highly stable across an eight-year interval from early adolescence to early adulthood. Furthermore, when compared with internalizing and externalizing symptoms, dramatic-erratic symptoms were more stable over time than these well-established Axis I symptom clusters. Based on high correlations with co-occurring internalizing and externalizing symptoms, Cluster B symptoms clearly reflect emotional distress during adolescence. These analyses reinforce recent efforts to establish personality disorders as a clinically significant and valid diagnostic construct in young people.
