[The Dutch Personality Inventory for DSM-5 (PID-5-NL): psychometric properties and clinical application]

The Dutch Personality Inventory for DSM-5 (PID-5-NL) is the APA recommended questionnaire to assess maladaptive personality traits as defined in the Alternative DSM-5 model of personality disorders.

To describe of the psychometric qualities of the PID-5-NL, present of normative data and apply the PID-5-NL in clinical practice.

The PID-5-NL was administered in a sample of adults from the general population in Flanders (Belgium) and in a sample of patients with a personality disorder in mental health care in the Netherlands. Scores on the PID-5 of a patient with borderline personality disorder are illustrated in a case vignette.

Reliability and validity of the PID-5-NL were satisfactory to good, and comparable with results from international research on the PID-5. It was remarkable that in the current research group, patients scored as low as or even lower than the group from the general population on a number of trait facets.

The PID-5-NL questionnaire is a useful tool to gain insight in a straightforward way into a wide range of relevant personality traits for diagnosis and treatment planning; provisional reference groups for the clinical practice in regular mental health care are made available on the basis of this study. Further refinement of the reference groups and further research within patients with externalizing personality problems is recommended.
