Assessing self-reported clinical high risk symptoms in community-derived adolescents: A psychometric evaluation of the prodromal questionnaire-brief

The reliable early identification of individuals at risk for psychosis requires well-validated screening measures. To date, there is little information about the psychometric properties of the screening measures for psychosis risk in nonclinical adolescents. The main purpose of the present study was to validate the Prodromal Questionnaire-Brief (PQ-B) in a community sample of non-clinical Spanish adolescents. We also analyzed the prevalence, factorial validity, and reliability of the PQ-B scores as well as the relationship between self-reported clinical high risk symptoms and schizotypal traits.
