The study found that the Rust Inventory of Schizotypal Cognitions (RISC) and the Eysenck Personality Questionnaire (EPQ) Psychoticism scale showed minimal correlation. This suggests distinct dimensions within the schizophrenia spectrum, with EPQ measuring personality disorder traits rather than general psychoticism.

Area of Science:

Psychology
Psychiatry

Background:

The schizoid dimension of personality was traditionally viewed as a single entity.
Recent research suggests multiple dimensions may constitute the schizoid spectrum.

Purpose of the Study:

To investigate the dimensional structure of personality within the psychoticism domain.
To differentiate between positive cognitive schizotypal traits and general psychoticism.

Main Methods:

Administered the Rust Inventory of Schizotypal Cognitions (RISC) and the Eysenck Personality Questionnaire (EPQ) P scale.
Collected data from 608 Venezuelan university students.

Main Results:

Found a low correlation (0.12) between the RISC and EPQ P scale.
The EPQ Psychoticism scale demonstrated a weak association with positive cognitive schizotypal dimensions.

Conclusions:

Concluded that at least two distinct dimensions exist within the schizophrenia/normal spectrum.
Suggested the EPQ Psychoticism scale measures a personality disorder dimension, not a general psychoticism factor.
