Validation of the Spanish version of the Cardiff Anomalous Perceptions Scale in the general population

Abstract

Introduction. Interest in the existence of anomalous perceptions in the general population has increased greatly over recent years. Because of this, it has been possible to extend the knowledge regarding the theory of psychosis as a dimensional model. This study has aimed to validate the Spanish version of the Cardiff Anomalous Perceptions Scale (CAPS) the general population.

Method. A descriptive, controlled and cross-sectional study was performed. It evaluated 324 participants from the general population with the Spanish translation of the CAPS, the 21-item Peter et al Delusions Inventory, the Revised Launay-Slade Hallucinations Scale and the reduced Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE).

Results. The results indicate that the Spanish version of the CAPS has good internal consistency and test-retest reliability. Analysis of the relationship with other scales indicates evidence of good convergent and divergent validity and the exploratory and confirmatory factor analysis of the CAPS showed a structure with three consistent factors.

Conclusions. The Spanish version of the CAPS is a valid and reliable psychometric measure of the anomalous perceptual experiences in the general population.
