Background and Objectives：Brief psychosis is not a sharply demarcated and little is known its nosological entity.
Previous studies indicate that 30% to 60% of patients with acute transient psychotic disorder (ATPD) are rediagnosed with bipolar disorder or schizophrenia but there is no way to expect who will be re-diagnosed as other disorder. The aim of this study was to evaluate the diagnostic stability of DSM-IV-TR recurrent brief psychotic disorder (BPD) retrospectively.
Method：We investigated 30 patients who had a first-ever admission as DSM-IVTR BPD and were re-admitted at least once to the psychiatric ward of the Asan Medical Center from 1989 to 2009. An analysis of re-admission pattern of all subjects was conducted.
Results：Only 10 cases retain their diagnosis on subsequent admission and diagnostic stability is 33.3%. The rest, 20 cases are re-diagnosed at the last；11 for bipovlar disorder, 4 for schizophrenia, 4 for schizoaffective disorder and 1 for schizophreniform disorder. No significant demographic, social or clinical predictors were found.
Conclusion：The findings imply the need for validation of the concept of BPD. We suggest that BPD have some similarities with bipolar spectrum disorder.
