The theory that the paranoid process is gradual and insidious was tested quantitatively by means of LISREL, a computer program designed to trace causal pathways between latent variables. The results clearly confirmed Lorr's simplex model which depicts a progressive sequence of six stages, beginning with hostile attitude and ending with delusions of influence. The model suggests that it is artificial to distinguish paranoid personality, paranoia and paranoid schizophrenia as separate diagnostic entities. Instead, paranoid schizophrenia should be regarded as a more severe form of paranoia which in turn is a more severe form of paranoid personality. The implications of this model for prognosis are also discussed.
偏执过程是渐进且隐匿的这一理论，通过LISREL进行了定量检验，LISREL是一个旨在追踪潜在变量之间因果路径的计算机程序。结果明确证实了洛尔的单维模型，该模型描绘了一个从敌对态度开始、以被控制妄想结束的六个阶段的递进序列。该模型表明，将偏执型人格、偏执狂和偏执型精神分裂症区分为不同的诊断实体是人为的。相反，偏执型精神分裂症应被视为偏执狂的一种更严重形式，而偏执狂又是偏执型人格的一种更严重形式。还讨论了该模型对预后的影响。
