Is schizophrenic symptomatology independent of the phase of the illness?

The difference in symptomatology between the acute and post-acute phase of schizophrenia was examined in the present study using prospective and longitudinal assessment of 86 newly admitted schizophrenic patients. In the acute phase of illness, four symptom components emerged (negative symptoms, excited, delusional/hallucinatory, and thought disorder) and three components were evident (negative symptoms, mixed symptoms, and thought disorder) in the post-acute phase. The negative component in the post-acute phase had the same composition as that in the acute phase.
