Convergent and discriminant validity of attenuated psychosis screening tools.
Brief self-report questionnaires that assess attenuated psychotic symptoms have the potential to screen many people who may benefit from clinical monitoring, further evaluation, or early intervention. The extent to which recently developed screening instruments demonstrate sound psychometric properties is an important issue toward the implementation of these measures in clinical practice. This study examines the convergent validity, discriminant validity, and test-retest reliability of four recently developed screening instruments. Screening instruments were included in an assessment battery and administered to a sample of 355 college students. Screening scores support the convergent and discriminant validity and the test-retest reliability of these measures.
