Figure.
Diagnostic stability of initial DSM-IV diagnoses (with prevalences [%]) among 500 first-episode psychotic disorder patients at first-lifetime hospitalization, ranked by diagnostic stability for the same subjects at two-years follow-up (% remaining unchanged). One case initially and finally diagnosed as schizoaffective disorder is omitted. Note that diagnostic stability ranged from 96.5% for bipolar I disorder (best for pure mania) to only 10.5% for schizophreniform disorder.
