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.
