Previous works concerning emotion regulation in psychosis highlighted the relationship between expressive suppression and negative psychotic symptoms, as well as between expressive suppression and auditory hallucinations. However, a direct association between suppression and delusions has not been observed. In the study we examined whether expressive suppression is associated with psychotic-like experiences and whether it may influence delusion-like experiences by changing the impact of cognitive biases on delusional beliefs.
Two hundred and twenty-one healthy individuals never diagnosed with psychiatric disorders completed self-report questionnaires measuring: delusion-like experiences, hallucinatory-like experiences, cognitive biases and expressive suppression. Regression and moderation analyses were performed.
Regression analyses revealed that the overall level of suppression predicts hallucinatory-like experiences, but not delusion-like experiences. Suppression of anxiety and suppression of sadness were significant predictors of hallucinatory-like experiences, whereas suppression of anxiety predicted delusion-like experiences. A moderation analysis indicated that both the overall level of suppression and suppression of sadness moderate the relationship between belief inflexibility and delusion-like experiences in such a way that belief inflexibility increases delusion-like experiences only among individuals reporting a low level of suppression.
Our findings confirmed that expressive suppression has a direct impact on hallucinatory-like experiences and suggest that the use of suppression may influence delusion-like experiences by moderating the impact of belief inflexibility on delusional thinking.
之前关于精神病患者情绪调节的研究强调了表达抑制与负面精神病症状之间的关系，以及表达抑制与幻听之间的关系。然而，抑制与妄想之间并没有直接的关联。在这项研究中，我们检验了表达抑制是否与类精神病体验有关，以及它是否可以通过改变认知偏差对妄想信念的影响来影响类妄想体验。
221 名从未被诊断为精神障碍的健康个体完成了自我报告问卷，测量：类妄想体验、类幻觉体验、认知偏差和表达抑制。进行了回归和调节分析。
回归分析显示，总体抑制水平预测类幻觉体验，但不预测类妄想体验。焦虑抑制和悲伤抑制是类幻觉体验的显著预测因子，而焦虑抑制则是类妄想体验的预测因子。一项调节分析表明，抑制的总体水平和悲伤抑制都调节了信念灵活性与类妄想体验之间的关系，以至于信念灵活性只在报告低抑制水平的个体中增加类妄想体验。
我们的发现证实了表达抑制对类幻觉体验有直接影响，并表明抑制的使用可能通过调节信念灵活性对妄想思维的影响来影响类妄想体验。
