Intention of the study is to examine, if the symptomatology of dual diagnosis patients is less severe after a special indication training for reduction of cannabis consumption in comparison to unspecified trainings.
Point of interest is psychopathology and consumerism.
Dual diagnosis patients (psychosis and cannabis abuse) account for more clinical admissions than single diagnosis patients.
Cannabis misuse is a known risk factor for recurrence of psychosis.
A specified intervention on the basis of a manual for schizophrenic substance abusers is administered to inpatients in a specialized unit for young schizophrenic patients in a psychiatric hospital.
The control group, same indication (psychotic disorder and cannabis misuse) receives social competence training (specified for schizophrenic patients as well).
Admission to groups is randomly.
1,655 studies on the registry are indexed under Psychotic Disorders; 298 are open to participants now.
