An extreme overvalued belief is shared by others in a person's cultural, religious, or subcultural group. The belief is often relished, amplified, and defended by the possessor of the belief and should be differentiated from a delusion or obsession. Over time, the belief grows more dominant, more refined, and more resistant to challenge. The individual has an intense emotional commitment to the belief and may carry out violent behavior in its service. Study participants (n = 109 forensic psychiatrists) were asked to select among three definitions (i.e., obsession, delusion, and extreme overvalued belief) as the motive for the criminal behavior seen in 12 randomized fictional vignettes. Strong interrater agreement (kappa = 0.91 [95% CI 0.83-0.98]) was seen for vignettes representing extreme overvalued belief. Vignettes representing delusion and obsession also had strong reliability (kappa = 0.99 for delusion and 0.98 for obsession). This preliminary report suggests that forensic psychiatrists, given proper definitions, possess a substantial ability to identify delusion, obsession, and extreme overvalued belief. The rich historical foundation of extreme overvalued belief and this small survey study highlight the benefit of inclusion of "extreme overvalued belief" in future glossaries of the Diagnostic and Statistical Manual.

极端高估的信念。

在一个人的文化，宗教或亚文化群体中，其他人也具有极端高估的信念。信念经常被信念的拥有者所津津乐道，扩大和捍卫，应该与妄想或痴迷区分开。随着时间的流逝，信念变得越来越占支配地位，变得更加精致，并且更能抵抗挑战。个人对信念有强烈的情感承诺，并可能在服务中进行暴力行为。研究参与者（n = 109名法医精神科医生）被要求从三个定义（即痴迷，妄想和极端高估的信念）中进行选择，以作为在12个随机的虚构插图中看到的犯罪行为的动机。对于代表极端高估信念的小插曲，人们看到了强烈的跨界一致性（kappa = 0.91 [95％CI 0.83-0.98]）。代表妄想和痴迷的小插图也具有很强的可靠性（错觉的kappa = 0.99，痴迷的kappa = 0.98）。这份初步报告表明，经过适当定义的法医精神科医生具有识别妄想，痴迷和极端高估信念的强大能力。极端高估信念的丰富历史基础和这项小型调查研究突显了在《诊断与统计手册》的未来词汇表中包含“极端高估信念”的好处。
