Detaljeret beskrivelse
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.
