Studies of person perception (people's impressions and beliefs about others) have developed important concepts and methods that can be used to help improve the assessment of personality disorders. They may also inspire advances in our knowledge of the nature and origins of these conditions. Information collected from peers and other types of informants is reliable and provides a perspective that often differs substantially from that obtained using questionnaires and interviews. For some purposes, this information is quite useful. Much remains to be learned about the incremental validity (and potential biases) associated with data from various kinds of informants.
对人物感知（人们对他人的印象和信念）的研究已经形成了重要的概念和方法，可用于帮助改进人格障碍的评估。它们还可能激发我们对这些病症的本质和起源的认识取得进展。从同伴和其他类型的信息提供者那里收集到的信息是可靠的，并且提供了一种视角，这种视角通常与通过问卷调查和访谈获得的视角有很大不同。出于某些目的，这些信息非常有用。关于与各类信息提供者的数据相关的增量效度（以及潜在偏差），仍有许多有待了解。
