Abstract

The study aims to identify psychopathologic variables in
cannabis-induced psychosis and recent-onset primary psychoses using the
Symptom Checklist-90-R and the Psychiatric Research Interview for
Substance and Mental Disorders. A sample of 181 subjects with psychotic
symptoms and cannabis use referred to the psychiatry inpatient units of 3
university general hospitals were assessed. The final sample included
50 subjects with a diagnosis of cannabis-induced psychotic disorder
(CIPD) and 104 subjects with primary psychotic disorders. Using receiver
operating characteristic curves, the most efficient psychopathologic
variables for classifying CIPD were interpersonal sensitivity,
"depression," phobic anxiety, and Scale to Assess Unawareness of Mental
Disorders subscales. The area under the receiver operating
characteristic curve of the model including depression and
"misattribution" scores was 96.78% (95% confidence interval,
94.43-99.13). Depressive symptoms could be used to distinguish CIPD from
other primary psychotic disorders. Clinical variables related to
"neurotic" symptoms could be involved in the susceptibility to
cannabis-induced psychosis.
