Factor Structure, Convergent, and Divergent Validity of the Prodromal Questionnaire-Negative Symptom Subscale.

ABSTRACT: Negative symptoms such as anhedonia are associated with psychosis risk and poorer outcomes. The Prodromal Questionnaire (PQ) is a self-report questionnaire used to screen for psychosis spectrum symptoms. However, the convergent and divergent validity and underlying factor structure of the PQ-negative symptom subscale (PQ-N) have yet to be examined.
