Rating the severity and character of transient cocaine-induced delusions and hallucinations with a new instrument, the Scale for Assessment of Positive Symptoms for Cocaine-Induced Psychosis (SAPS-CIP)

The results suggest that CIP consists of transient delusional and hallucinatory symptoms, which tend to occur together and co-vary in severity. It appears that rating cocaine-induced paranoia alone (e.g., with the CEQ) can identify most subjects experiencing CIP. However, the SAPS-CIP is useful for quantifying the severity of CIP according to operational criteria. Our data provide additional evidence that CIP is a sensitizing response.
