Screening for psychosis risk among adolescents in Child and Adolescent Mental Health Services: a description of the first step with the 16‐item version of the Prodromal Questionnaire (PQ‐16)

Abstract

The PQ-16 is easy to implement in routine assessment and can be useful to bring up potential psychotic symptoms for further exploration in an early stage, especially in adolescents with low Global Assessment of Functioning scores. The PQ-16 total scores were not confounded by differences in age, gender or disorder. Future research should investigate the true nature of PQ-16 items and whether the item scores and cut-off scores of the PQ-16 in adolescence have any predictive value regarding the development of an ultra high-risk status, a psychotic disorder or other mental disorders.
