[Psychometric properties of PANSS (Positive and Negative Syndrome Scale) in the French version in a sample of schizophrenic patients]. / Etude des propriétés psychométriques de la PANSS dans sa version française dans une population de patients schizophrènes.

ABSTRACT

Our study focuses on psychometrics properties of the french version of the Positive and Negative Syndrom Scale (PANSS). 85 schizophrenic subjects, in accordance with DSM III-R criteria were included in this study. Our results allow us to discuss the construct validity and the reliability of this scale. The traditional 3 dimensions of the PANSS (positive, negative and general psychopathology) are discuss. We show that expect positive scale and general psychopathology scale average several symptomatic dimensions. We propose a 5 dimensions solution (negative, hostility, positive, disorganization, anxiety), which represent 54% of the total inertie. The internal consistency of this solution is presented.
