Аннотация

BACKGROUND

This study reports a new measure of psychotomimetic states in the context of cannabis and ketamine use. The Psychotomimetic States Inventory (PSI) has sub-scales of Delusory Thinking, Perceptual Distortions, Cognitive Disorganization, Anhedonia, Mania and Paranoia.

METHODS

The PSI was administered in two independent group, repeated measures designs: an experimental study of ketamine and a naturalistic study of cannabis.

RESULTS

Both cannabis and ketamine produced reliable increases in ratings of psychotomimetic state effects across several sub-scales.

CONCLUSIONS

The PSI is a potentially useful measure of the nature and extent of the phenomenological effects of psychotropic drugs in schizophrenia-related research.
