The present study explored possible connections between neuroleptic do
se and the positive and negative symptoms of schizophrenic patients. Z
ero-order correlations between medication dose as measured in CPZ equi
valent units and standardized assessments of positive (hallucinations,
delusions) and negative (blunted affect, poor rapport) symptoms were
carried out on 28 hospitalized schizophrenics. While dose was positive
ly related to over-all negative symptom scores as well as specific neg
ative symptoms, no relation was found with positive scores. The discus
sion focused on the possibility that negative symptoms might represent
medication-induced side effects and the need for further research.
