Comments on an article by Bornstein (see record 2018-27549-001). Dr. Bornstein represents well the perspective of a prominent faction within the personality disorder field with regard to the dimensional- categorical debate, but Widiger would respectfully suggest that this perspective may not represent sufficiently well the relevant empirical research. As Dr. Bornstein acknowledges, "In recent years the dimensional approach has been in ascendance" (Bornstein, 2019, p. 199), perhaps precisely because the evidence has been strongly in its favor. In sum, Widiger would suggest that the dimensional trait models do translate naturally into diagnoses (when desired or needed), are easily communicated to other healthcare professionals, and will account well for the intra- and interpersonal dynamics. Scales to assess some of these dynamics have already been constructed. Widiger agrees that the trait and dynamic clinicians should work more collaboratively.
