The ICD-11 has a new diagnostic system for personality disorder, which includes five optional trait specifiers to characterize the diagnosed pathology. The current study evaluated the internal structure and construct validity of the Personality Assessment Questionnaire for ICD-11 (PAQ-11) personality trait domains in a US population-representative community sample. An exploratory factor analysis revealed the support for a four-factor model underlying the 17 PAQ-11 items, reflecting four of the five ICD-11 trait domains (Negative Affectivity, Detachment, Disinhibition and Anankastia). Moreover, correlation analyses revealed that the PAQ-11 domain scale scores were associated, as expected, with their counterparts from two other ICD-11 trait domain measures, as well as with traditional personality disorder scores. More broadly, the results raised questions about the structural integrity of the Dissociality domain scale, and the discriminant validity of the Disinhibition and Anankastia scales. The overall conclusion was nevertheless promising with respect to the PAQ-11 serving as a brief screening measure for the ICD-11 trait domains.
