Despite the widely held belief that paranoid behavior is associated with good premorbid adjustment, low chronicity, and high current functioning in psychiatric inpatients, inconsistencies in the literature suggest that supportive evidence may be an artifact of the measurement model commonly used to index paranoid status. In a sample of 497 nonorganic inpatients selected from 19 treatment units, paranoid behavior, when measured by a dimensional/cumulative model, was not found to indicate higher functioning and associated relationships, but simply to reflect a narrower class of problem behavior. Only when paranoid status was defined using a traditional model based on the predominance of the defining class of behavior did paranoid subjects demonstrate better premorbid adjustment, lower chronicity, and higher levels of functioning than nonparanoid subjects. Serious problems exist in the use of information obtained from traditional predominance/class models for either theoretical or practical purposes.
尽管人们普遍认为偏执行为与病前良好适应、低慢性病程度以及精神科住院患者的高当前功能有关，但文献中的不一致表明，支持性证据可能是常用于索引偏执状态的测量模型的产物。在从19个治疗单元中选取的497名非器质性住院患者样本中，当通过维度/累积模型测量时，未发现偏执行为表明更高的功能及相关关系，而仅仅反映了一类更狭窄的问题行为。只有当使用基于定义行为类别的优势的传统模型来定义偏执状态时，偏执患者才比非偏执患者表现出更好的病前适应、更低的慢性病程度和更高的功能水平。使用从传统优势/类别模型获得的信息用于理论或实际目的存在严重问题。
