越来越多的研究表明，偏执狂在普通人群中很常见。我们报告了三项研究，检验囚徒困境博弈（PDG）作为非临床偏执评估的范例。 PDG 抓住了偏执狂的三个关键品质：人际交往、威胁以及他人对自我意图的感知。研究 1 (n=175) 发现状态偏执与竞争性 PDG 选择呈正相关。研究 2 (n=111) 发现，只有当参与者相信他们正在与另一个人玩 PDG 时，这种关联才显着，而在与计算机玩时则不显着。这一发现强调了偏执狂的人际本质以及在人际背景下研究偏执狂的必要性。在研究 3（n=152）中，我们评估了特质和状态偏执，并区分了基于不信任和贪婪的竞争。特质和状态偏执都与基于不信任的竞争呈正相关（但与基于贪婪的竞争无关）。至关重要的是，我们发现特质偏执和基于不信任的竞争之间的关联完全是由国家偏执调节的。 PDG 是研究非临床偏执狂的一个有前途的范例。
A growing body of research shows that paranoia is common in the general population. We report three studies that examined the Prisoner's Dilemma Game (PDG) as a paradigm for evaluation of non-clinical paranoia. The PDG captures three key qualities that are at the heart of paranoiait is interpersonal, it concerns threat, and it concerns the perception of others' intentions towards the self. Study 1 (n=175) found that state paranoia was positively associated with selection of the competitive PDG choice. Study 2 (n=111) found that this association was significant only when participants believed they were playing the PDG against another person, and not when playing against a computer. This finding underscores the interpersonal nature of paranoia and the concomitant necessity of studying paranoia in interpersonal context. In Study 3 (n=152), we assessed both trait and state paranoia, and differentiated between distrust- and greed-based competition. Both trait and state paranoia were positively associated with distrust-based competition (but not with greed-based competition). Crucially, we found that the association between trait paranoia and distrust-based competition was fully mediated by state paranoia. The PDG is a promising paradigm for the study of non-clinical paranoia.
