Suggestions have been made that psychotic‐like experiences (PLEs), such as hallucinatory and delusional experiences, exist on a continuum from healthy individuals to patients with a diagnosis of schizophrenia. We used the screening questions of the Questionnaire for Psychotic Experiences (QPE), an interview that captures the presence and phenomenology of various psychotic experiences separately, to assess PLEs in Norway. Based on data from an online survey in a sample of more than 1,400 participants, we demonstrated that the QPE screening questions show satisfactory psychometric properties. Participants with mental disorders reported more frequent lifetime and current hallucinatory experiences than participants without mental disorders. Childhood experiences were rather low and ranged from 0.7% to 5.2%. We further replicated findings that young age, illegal drug use, lower level of education, and having parents with a mental disorder are associated with higher endorsement rates of PLEs. Finally, a binomial regression revealed that the mere presence of PLEs does not discriminate between individuals with and without a mental disorder. Taken together, the findings of the present study support existing models that both hallucinations and delusions exist on a structural and phenomenological continuum. Moreover, we demonstrated that the QPE screening questions can be used by themselves as a complementary tool to the full QPE interview.

绘制类似精神病的经历:在线调查的结果

有人建议,从健康的个体到诊断为精神分裂症的患者,都存在着类似幻觉的经历(PLEs),例如幻觉和妄想经历。我们使用了《心理经历调查表》(QPE)的筛查问题,该访谈是一次访谈,它分别记录了各种精神病经历的存在和现象,以评估挪威的PLE。基于对来自1400多个参与者的样本进行的在线调查数据,我们证明了QPE筛查问题显示出令人满意的心理测量特性。与没有精神障碍的参与者相比,患有精神障碍的参与者报告了更频繁的一生和当前的幻觉经历。童年经历相当低,介于0.7%至5.2%之间。我们进一步复制了发现,即年轻,非法吸毒,较低的教育水平以及父母患有精神障碍与PLE的认可率较高相关。最后,二项式回归显示,仅存在PLE并不能区分有精神障碍和没有精神障碍的个体。两者合计,本研究的发现支持现有的模型,幻觉和妄想都存在于结构和现象学的连续体上。此外,我们证明了QPE筛选问题本身可以用作完整QPE面试的补充工具。二项式回归表明,仅存在PLE并不能区分有精神障碍和没有精神障碍的个体。两者合计,本研究的发现支持现有的模型,幻觉和妄想都存在于结构和现象学的连续体上。此外,我们证明了QPE筛选问题本身可以用作完整QPE面试的补充工具。二项式回归表明,仅存在PLE并不能区分有精神障碍和没有精神障碍的个体。两者合计,本研究的发现支持现有的模型,幻觉和妄想都存在于结构和现象学的连续体上。此外,我们证明了QPE筛选问题本身可以用作完整QPE面试的补充工具。
