Continuity Between DSM–5 Section II and III Personality Disorders in a Dutch Clinical Sample

The goal of this study was to evaluate the continuity across the Section II personality disorders (PDs) and the proposed Section III model of PDs in the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM–5]; American Psychiatric Association, 2013a American Psychiatric Association. (2013a). Diagnostic and statistical manual of mental disorders (5th ed.). Washington, DC: American Psychiatric Association.[Crossref] , [Google Scholar]). More specifically, we analyzed association between the DSM–5 Section III pathological trait facets and Section II PDs among 110 Dutch adults (M age = 35.8 years, range = 19–60 years) receiving mental health care. We administered the Structured Clinical Interview for DSM–IV Axis II Disorders to all participants. Participants also completed the self-report Personality Inventory for DSM–5 (PID–5) as a measure of pathological trait facets. The distributions underlying the dependent variable were modeled as criterion counts, using negative binomial regression. The results provided some support for the validity of the PID–5 and the DSM–5 Section III Alternative Model, although analyses did not show a perfect match. Both at the trait level and the domain level, analyses showed mixed evidence of significant relationships between the PID–5 trait facets and domains with the traditional DSM–IV PDs.
