The CGI-I scale is a clinician-rated scale to assess illness improvement. The CGI-I scale includes one item scored from 1 (Very much less anxious) to 7 (Very much more anxious) with 4 being no change. Subjects are considered CGI-I responders with scores of 1 (Very much less anxious) or 2 (Much less anxious).
