In this study, we asked people from two samples (a clinical one, consisting of patients with schizophrenia, and a non-clinical one, including university students) to complete the Revised Hallucination Scale (RHS) as a self-questionnaire. When the participants responded positively to an item, they were encouraged to provide further detailed descriptions (i.e., examples of their own experiences) concerning that item. We found that the kinds of descriptions provided by the two groups were very different. We suggest that it is not advisable to explore the presence of hallucinations in non-clinical samples using research protocols based exclusively on yes-or-no answers to questionnaires like the RHS. Hallucinatory or hallucinatory-like experiences cannot be reliably and validly assessed without a precise characterization of the phenomenal quality of the experience.
在这项研究中，我们要求来自两个样本（一个是临床样本，包括精神分裂症患者，另一个是非临床样本，包括大学生）的人完成修订后的幻觉量表（RHS）作为自我问卷。当参与者对一个项目做出肯定回答时，他们被鼓励提供关于该项目的进一步详细描述（即，他们自己经历的例子）。我们发现，这两组提供的描述非常不同。我们认为，使用仅基于 RHS 等问卷的是或否回答的研究方案来探索非临床样本中幻觉的存在是不可取的。如果没有对体验的现象质量进行精确描述，就无法可靠和有效地评估幻觉或类似幻觉的体验。
