FONSECA-PEDRERO, Eduardo et al. ESQUIZO-Q: An Instrument for the Assessment of "Psychometric High Risk" for Psychosis. Clínica y Salud [online]. 2010, vol.21, n.3, pp.255-269. ISSN 2174-0550.

The aim of the "psychometric high risk" paradigm is the detection, by means of self-report measures and based on score profiles, of those individuals with a higher theoretical vulnerability of moving toward a psychotic disorder in the future. The early detection of this type of at-risk individual requires adequate assessment instruments that allow us to make solid and well-founded decisions based on their scores. The main objective of this study was to present the construction and validation of a recently created self-report called ESQUIZO-Q: Cuestionario Oviedo para la Evaluación de la Esquizotipia (The Oviedo Schizotypy Assessment Questionnaire). The analysis of its internal structure revealed a three-factor solution: Distortion of Reality, Anhedonia and Interpersonal Disorganization. The levels of internal consistency for the ESQUIZO-Q subscales ranged from 0.62 to 0.90. No item showed differential functioning as a function of the gender of participants. Likewise, the ESQUIZO-Q subscales correlated moderately with the scales of other selfreports that assess depression, behavioral problems and personality disorder traits. The ESQUIZO-Q is a brief and easy self-report instrument with adequate psychometric properties that can be used as an epidemiological tool and as a psychopathological screening method in the general population. Future investigations should conduct longitudinal studies in order to examine the predictive capacity of the ESQUIZO-Q.
