The BPRS in assessing symptom correlates of cerebral ventricular enlargement in acute and chronic schizophrenia.
The present study was an attempt to investigate hypotheses about the interrelationship of brain dysfunction and symptoms of schizophrenia using the Brief Psychiatric Rating Scale (BPRS) and a measure of cerebral ventricular size. The ventricular brain ratio (VBR) was correlated with admission and discharge scores on the BPRS in 46 schizophrenic patients. A significant relationship was found between VBR and discharge BPRS scores. In general, the results were partially supportive of relationships found between neuropsychological data and the BPRS in a previous study, but shed little light on the relationships between brain damage and negative and positive symptoms. Limitations of using the BPRS, as well as possible sampling variations, are discussed.
