Research on personality disorders has revealed that they commonly suffer from excessive co-morbidity, arbitrary diagnostic thresholds, short-term diagnostic instability, and an unusually high occurrence of Personality Disorder Not Otherwise Specified (PDNOS). As of April 10, 2013, the DSM-5 proposes a significant revision in how clinicians assess and diagnose personality disorders which includes the use of a categorical-dimensional model with six specific personality disorder types (antisocial, avoidant, borderline, narcissistic, obsessive-compulsive, and schizotypal) along with a diagnosis of Personality Disorder Trait Specified (PDTS) which replaces PDNOS. The final published DSM-5 conceptualization might he different than what is known at this time. The diagnosis of PDTS will be the only diagnosis in which the dimensional model is fully implemented. Thus, this study explores the validity of the five proposed DSM-5 personality trait domains (negative affect, detachment, antagonism, disinhibition vs compulsivity, and psychoticism) in a dimensional model of personality in a sample of 128 clinical and 119 non-clinical participants who were recruited through internet postings, word of mouth, and through St. John's University's psychology department undergraduate subject pool. A subset of 105 items were selected from a set of 840 items drawn from the Personality Disorder Symptom Checklist (PDSC), Schedule of Nonadaptive Personality (SNAP) and the Revised NEO-Personality Inventory (NEO-PI-R), taking care to ensure that all proposed DSM-5 trait domains and facets were mapped. This item set was subjected to an EFA and a CFA. Overall, the empirically-derived five-factor EFA model was coherent and interpretable, possessed better fit statistics and internal consistency reliability estimates, and was associated in the expected ways with criterion validators when compared to the rationally-derived CFA model. In addition, the five factors identified in the EFA correspond closely with the five proposed DSM-5 trait domains, suggesting that the EFA provides modest support for the five proposed DSM-5 dimensions of personality. Future research should focus on utilizing data from a broader range of personality inventories like the Dimensional Assessment of Personality Pathology -- Basic Questionnaire (DAPP-BQ), the Personality Psychopathology Five (PSY-5), and the Dimensional Personality Symptom Item Pool (DIPSI).
