The diagnostic status of paranoia (renamed simple delusional disorder [SDD]) has been debated since the time of Kraepelin. Three main views have emerged that consider paranoia (1) a subtype of schizophrenia, (2) a subtype of affective illness, or (3) a distinct nosologic entity. The literature pertinent to the diagnostic validity of a SDD is examined. Although the methodology of a number of the studies reviewed would not be considered rigorous by today's standards, certain tentative conclusions can nonetheless be reached. The available data do not suggest that SDD is a subtype of affective illness. The evidence reviewed also does not strongly support the hypothesis that SDD is a subtype of schizophrenia. Although some of the data is consistent with the view that SDD is a "mild" form of schizophrenia, the bulk of the evidence suggests that SDD and schizophrenia are distinct syndromes.
自克雷佩林时代起，偏执狂（现更名为单纯妄想障碍[SDD]）的诊断地位就一直存在争议。出现了三种主要观点，认为偏执狂（1）是精神分裂症的一种亚型，（2）是情感性疾病的一种亚型，或（3）是一种独特的疾病分类实体。本文对与单纯妄想障碍诊断有效性相关的文献进行了研究。尽管按照当今的标准，所综述的一些研究方法并不被认为严谨，但仍可得出某些初步结论。现有数据并不表明单纯妄想障碍是情感性疾病的一种亚型。所综述的证据也并不强烈支持单纯妄想障碍是精神分裂症一种亚型的假说。尽管一些数据与单纯妄想障碍是精神分裂症“轻度”形式的观点一致，但大量证据表明单纯妄想障碍和精神分裂症是不同的综合征。
