title: An attempt to validate the psychoticism scale of the Brief Symptom Inventory.
abstract: This study attempted to validate the psychoticism scale of the Brief Symptom Inventory (BSI) by comparing 31 schizophrenic patients with 98 non-schizophrenic patients. Unexpectedly, the schizophrenics did not exceed the non-schizophrenics on the psychoticism symptom dimension. None of a variety of controls and comparisons provided a basis for dismissing the finding. A rationale was introduced explaining why any attempt to match symptoms with the diagnosis of schizophrenia can at best meet with only qualified success.
