WHAT THE TEST MEASURES
About This Assessment
Brief Prodromal Questionnaire, PQ-B Test

Prodromal Questionnaire–Brief Version (PQ-B) Test - Symptoms and Signs

psychopathology
schizophrenia

This brief self-report screener is used to identify possible early signs associated with emerging psychosis. The Prodromal Questionnaire-Brief Version (PQ-B) is intended to support initial risk detection and guide decisions about whether further assessment is warranted.

Respondents answer 21 items regarding recent experiences and perceptions, typically requiring about 4 minutes to complete. It is commonly used in clinical or counseling settings as part of an initial screening process and should not be interpreted as a standalone diagnostic tool. When indicated, elevated scores may prompt more comprehensive evaluation.

The Prodromal Questionnaire-Brief Version (PQ-B) is generally administered alongside other clinical information to inform referral and next-step assessment planning.
