OBJECTIVES: This paper presents results of a study on the Polish adaptation of the Personality Inventory for DSM-5 (PID-5), which was developed to measure pathological traits under a new, dimensional model proposed in Section III of the DSM-5 as part of a hybrid alternative system of personality disorder diagnosis.
METHODS: The study involved a clinical sample (N = 129 individuals with a mean age of M = 32.40; SD = 9.08; 84.5% with a personality disorder diagnosis) and a non-clinical one (N = 1,043 individuals with a mean age of M = 34.98; SD = 15.71). Two questionnaires: the PID-5 and the MMPI-2 (Minnesota MultiphasicPersonality Inventory - 2) were use in the study.
RESULTS: The results showed the Polish adaptation of the PID-5 to be reliable and valid (the internal consistency coefficients for the PID-5 scales and subscales were high in clinical sample and at satisfactory level in non-clinical sample). All scales and almost all subscales of the PID-5 turned out to differentiate between clinical and non-clinical samples. The PID-5 scales and subscales exhibited a consistent pattern of relationships with the Personality Psy-chopathology Five (PSY-5) dimensions and with the clinical scales of the MMPI-2.
CONCLUSIONS: Obtained data demonstrate the PID-5 to be a satisfactory operationalization of the pathological personality trait model, and at the same time corroborate the scientific value of the DSM-5 model itself.
