For the ICD-11, there is a scale of the severity of personality pathology that ranges from “personality difficulty” to “mild,” “moderate,” and “severe” personality disorder, which represent the only personality disorder “diagnoses” in the system. The designation of “personality difficulty” (subthreshold for a personality disorder), as well as the three levels of personality disorder, can all be amplified by these trait specifiers: negative affectivity, detachment, dissociality, disinhibition, or anankastia.
