- Number of participants with dissociative events during ketamine infusion as assessed by CADSS (Clinician-Administered Dissociative State Scale) [ Time Frame: up to 1 week ]The CADSS is an instrument for the measurement of dissociative symptoms. The CADSS comprises 23 subjective items and participant's responses are coded on a 5-point scale (0 = Not at all; 4 = Extreme). The higher the number on the CADSS, the more severe the symptoms.
