Cognitive-behavioral models of paranoia have emphasized the potential role of perseverative thinking styles, such as rumination or worry, in the development, maintenance and exacerbation of paranoid beliefs. This study aimed to experimentally test the hypothesis that rumination may play a role in the maintenance or exacerbation of state paranoid ideation. Following a paranoia induction, 37 nonclinical participants were randomly assigned to either a rumination task or a distraction control condition. In accord with main hypothesis, rumination was associated with maintained levels of paranoia, whereas distraction was associated with a decrease in levels of paranoia. These findings suggest that perseverative thinking may play a role in the maintenance of paranoid ideas, which may have implications for our understanding of the maintenance of paranoia and persecutory delusions in the clinical population. Furthermore, the study used a novel experimental paradigm for inducing paranoia, which may prove valuable for future research aiming to elicit paranoid thoughts and feelings in vivo.
偏执认知-行为模型强调了持续思维模式（如反刍或担忧）在偏执信念的发展、维持和加剧中的潜在作用。本研究旨在通过实验测试反刍是否可能在维持或加剧状态偏执观念中起作用的假设。在偏执观念诱发后，37 名非临床参与者被随机分配到反刍任务或分心控制条件中。与主要假设一致，反刍与偏执观念的维持水平相关，而分心与偏执观念水平的降低相关。这些发现表明，持续思维可能在维持偏执观念中起作用，这可能对我们理解临床人群中偏执和被害妄想的维持具有重要意义。此外，该研究使用了一种新颖的实验范式来诱发偏执，这可能对未来旨在在体内引发偏执思想和感觉的研究具有重要价值。
