A taxometric study of borderline personality disorder.
Taxometric methodology was used to determine whether borderline personality disorder (BPD) represents a taxon that is categorically distinct from normal personality or whether it falls on a dimensional continuum with normality. Two taxometric procedures were used with a sample of 1,389 outpatients assessed for BPD symptoms by semistructured interview. The procedures indicated that BPD does not represent a latent category. Implications are drawn for the conceptualization and etiology of BPD, and for the categorical versus dimensional status of personality disorders in general.
