We conducted a cross-sectional study including a sample of
169 patients recruited from our inpatient unit (n¼133, 78.7%) and
our outpatient clinic (n¼36, 21.3%). Patients were included if they
were clinically stable and had a diagnosis of psychotic disorder.
Psychotic disorders included DSM-IV schizophrenia, schizophreniform
disorder, schizoaffective disorder, affective disorder with a
current episode with psychotic symptoms, brief psychotic disorder,
atypical psychosis and delusional disorder (APA, 1994). Exclusion
criteria were: a clear-cut affective episode without psychotic
symptoms; major sensory or motor disabilities; mental retardation
or any diagnosed brain disorder; and a primary diagnosis, or
clinically dominant secondary diagnosis, of severe substance
abuse. In addition, severely psychotic, aggressive or ‘involuntarily
admitted’ patients were not included in the study
