Summary

The stability of symptomatology and of eleven schizophrenic diagnostic systems was studied in patients initially in an acute phase (group 1) compared to patients in a residual phase (group 2). The patients were evaluated over a period of 1 year with a standardized checklist and PANSS in both groups. The number of patients included by the Carpenter, Calego, 1CD9, New-Haven, Schneider and Vienne systems decreased significantly between admission and discharge in group 1, whereas no variation was observed in group 1 between discharge and one year later, or in group 2 over a period of 1 year. The instability of schizophrenic diagnostic systems such as New-Haven, Schneider and Vienne could be due to the variation of positive or general symptomatology. The number of patients included by Feighner or Langfeldt did not vary significantly between admission and discbarge in group 1, in spite of a significant decrease in symptomatology, probably because certain criteria, such as duration of illness, hindered the systems from changing. The results showed the importance of specifying in every study on schizophrenia the time of inclusion (admission, discharge) or the phase of illness (acute or residual phase).
