The ICD-11 classification of personality disorders (PDs) has adopted a dimensional approach which includes three levels of severity (mild, moderate and severe) with the option of specifying five trait qualifiers (negative affectivity, detachment, dissociality, disinhibition and anankastia) and one borderline pattern qualifier. This study examined mental health professionals' perceived clinical utility of the ICD-11 PD framework compared with the ICD-10 categorical PD framework.
