Participant Flow

Participants were recruited from outpatient clinics at VA Greater Los Angeles Health care system and local mental health facilities. All patients met Diagnostic and Statistical Manual-IV criteria for schizophrenia, schizoaffective disorder, delusional disorder, or psychosis not otherwise specified (not secondary to substance use disorder)

This is not a drug study so there is no wash out or run in. Participants were excluded if they did not meet diagnostic criteria.
