WHAT THE TEST MEASURES

About This Assessment

Panic Disorder Screener (PHQ-PD) Test - Symptoms and Signs

panic disorder psychopathology

This self-report screening measure is used to identify symptoms consistent with panic attacks and possible panic disorder. The Panic Disorder Screener (PHQ-PD) is typically administered as an initial step to support clinical decision-making and determine whether further diagnostic assessment is indicated.

It consists of 15 items and generally takes about 3 minutes to complete. Items query the presence and associated features of panic episodes and related distress, supporting a structured review of symptoms in primary care and behavioral health settings. The Panic Disorder Screener (PHQ-PD) was developed by K. Kroenke, R. L. Spitzer, and J. B. W. Williams and should be interpreted in the context of clinical interview and other relevant information.
