The six personality disorder (PD) types in DSM-5 section III are intended to resemble their DSM-IV/DSM-5 section II PD counterparts, but are now described by the level of personality functioning (criterion A) and an assigned trait profile (criterion B). However, concerns have been raised about the validity of these PD types. The present study examined the continuity between the DSM-IV/DSM-5 section II PDs and the corresponding trait profiles of the six DSM-5 section III PDs in a sample of 350 Dutch psychiatric patients. Facets of the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ) were presumed as representations (proxies) of the DSM-5 section III traits. Correlational patterns between the DAPP-BQ and the six PDs were consistent with previous research between DAPP-BQ and DSM-IV PDs. Moreover, DAPP-BQ proxies were able to predict the six selected PDs. However, the assigned trait profile for each PD didn't fully match the corresponding PD.
