The PDSS is a 7-item measure that assesses the severity of symptoms for those diagnosed with panic disorder. This is the self-report version; the original scale is normally completed by clinicians, and used for monitoring purposes.
Created by Dr. M. Katherine Shear and colleagues. The scale has been published by the authors and widely distributed, though Dr. Shear retains copyright. It may be used by clinicians in their practice and for researchers in non-industry studies.
Self-report scales are for screening purposes only, and must be interpreted by a qualified health professional in conjunction with clinical assessment. They cannot be used alone for diagnostic or treatment purposes.
