10.23. Clinical Global Impressions scale (CGI)¶
The CGI rates illness severity, global improvement, and the efficacy/side-effect balance of treatment. The CGI-I is a subset with just the improvement subscale.
10.23.1. History and guide¶

Guy (1976), as above.
A trivial modification has been made: questions are asked about therapeutic effect and side effects separately, and are then combined to give the same score as the original CGI method (which required a simultaneous rating on those two dimensions).
