目的是研究未定型精神分裂症的临床表现、特征，在分类中的地位等。方法采用ＣＣＭＤ－２－Ｒ、ＤＳＭ－Ⅳ、ＩＣＤ－１０对１９９５年我院精神科出院的精神分裂症重新诊断、评定分型（一致性＝０．９，Ｋａｐｐａ＝０．８，Ｐ＜０．０１））。结果未定型为２０２例（７９．５％），占同期出院精神分裂症的３５．３％。结论未定型精神分裂症所占比例的增加与精神药物的应用、社会文化等多种因素有关；未定型既有阴性症状，又有阳性症状，具有Ａｎｄｒｅａｓｅｎ混合型精神分裂症的特征。建议在开展对阴、阳性精神分裂症研究的同时，应重视对混合型的研究，将有助于对精神分裂症异质性的探讨。
The purpose is to study the clinical manifestations, characteristics of undifferentiated schizophrenia, the status of the classification and so on. Methods The schizophrenia patients discharged from psychiatric hospital in our hospital in 1995 were re-diagnosed by CCMD-2-R, DSM-Ⅳ and ICD-10, and the typing was evaluated (consistency = 0.9, Kappa = 0.8, P <0 .01)). The results were undetermined 202 cases (79.5%), accounting for 35.3% of schizophrenia discharged during the same period. Conclusion The increasing proportion of unspecific schizophrenia is related to the application of psychotropic drugs, social culture and other factors. Undetermined type has both negative and positive symptoms, and is characterized by Andreasen mixed schizophrenia. It is suggested that in the study of negative and positive schizophrenia, attention should be paid to the study of mixed type, which will be helpful to explore the heterogeneity of schizophrenia.
