Psychometric validation of the consensus five-factor model of the Positive and Negative Syndrome Scale.

Background: The Positive and Negative Syndrome Scale (PANSS) is widely used for clinical assessment of symptoms in schizophrenia. Instead of the traditional pyramidal model, recent literature supports the pentagonal model for the dimensionality of the PANSS.

Aim: The present study aimed to validate the consensus five-factor model of the PANSS and evaluate its convergent validity.
