Clinical Global Impressions scale - CGI

 

The Clinical Global Impressions scale - CGI is a 3-item observer-rated scale commonly used to measure symptom severity, global improvement, and therapeutic response. Each component of the CGI is rated separately; it does not yield a global score. Items 1 and 2 are rated on a 7-point scale; item 3 is rated from 0 to 4 (when rating item 3, therapeutic efficacy and treatment-related adverse events should be taken into account).
