title: The hierarchical structure of the Dimensional Assessment of Personality Pathology (DAPP-BQ).
abstract: Hierarchical personality models have the potential to identify common and specific components of DSM-IV personality disorders (PDs), and may offer a solution for the re-tooling of personality pathology in future versions of the DSM. In this paper, we examined the hierarchical structure of the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ; Livesley & Jackson, 2009) and the capacity of various trait components at different levels to predict DSM-IV PD symptoms. Participants were 275 psychiatric outpatients and 365 undergraduate students. Goldberg's (2006) bass-ackwards method was used to investigate the hierarchical structure of the DAPP-BQ. The predictive capacity of hierarchy components was assessed. We found that Level 5 of the hierarchy enhanced the capacity of the DAPP-BQ for predicting DSM PD symptoms beyond a four-factor structure, particularly for borderline PD.
