title: Sinistrality in schizophrenia.
abstract: Sinistrality characterized by an excess of non-right handedness has been reported in schizophrenic patients. Two factors, sex and kind of evaluation of handedness have contributed to major discrepancies across studies.
  
  
  OBJECTIVE
  The hypothesis tested was that schizophrenic patients show a sinistral shift in handedness compared to controls taking into account the sex and using a continuum scoring system for evaluating handedness.
  
  
  METHODS
  Seventy-three (73.1% males) schizophrenic patients (DSMIV) and 81 (64.2% males) controls were evaluated with the Edinburgh Handedness Inventory (EHI [Neuropsychologia, 9 (1971) 97]).
  
  
  RESULTS
  The EHI score mean difference between patients with schizophrenia and control group was not significant when sex was taken into account.
  
  
  CONCLUSIONS
  Schizophrenic patients taken as a whole did not show a sinistral shift in handedness even if the sex and the continuum score for handedness were considered.
