Evaluación de la propensión a la psicosis con el Esquizo-Q

Schizotypy, also known as psychosis proneness, is a variable that is closely related to schizophrenia. Its interest and study basically resides in its capacity to detect individuals with profiles of risk or vulnerability for psychosis and in the possibility of early detection and prompt intervention through prophylactic treatments. The early identification of these types of at-risk individuals requires us to have adequate measurement instruments that allow us to make solid, well-founded decisions based on their score profiles. To date, there is no measurement instrument specifically designed for the assessment of this construct in Spanish-speaking adolescent populations. The main objective of the present investigation was to analyze the process of construction and validation of a new self-report named ESQUIZO-Q: Cuestionario Oviedo para la Evaluación de la Esquizotipia (The Oviedo Schizotypy Assessment Questionnaire). The results show that the ESQUIZO-Q is a brief and simple measurement instrument with adequate psychometric properties for the assessment of schizotypy that can be used as an epidemiological tool and a psychopathological screening method in the general adolescent population. Future studies should continue to explore the metric quality of the ESQUIZO-Q (e.g., sensitivity and specificity) as well as its relationship with endophenotypes in other types of samples.
