The manual outlines a rigorous framework for clinicians to evaluate symptoms, severity, and functional impairment across a spectrum of anxiety-related conditions.

Clinicians and researchers widely recognize this instrument as a foundational tool for standardized diagnostic assessment in mental health settings. Professionals frequently note the high level of clinical rigor required to administer the interview effectively, making it a standard resource for advanced practitioners and academic training programs.
