Despite evidence that the reporting of delusion-like or hallucinatory experiences are predictive of the future development of a mental disorder in the spectrum of psychosis, the exact nature of such a kind of unusual subjective experience in the general population is still disputed. We investigated the multidimensionality of these experiences with the Peters et al. Delusions Inventory (PDI) and a modified Italian version of the Launay-Slade Hallucination Scale (LSHS-R) in 250 subjects of both genders drawn from the normal population, using the General Health Questionnaire (GHQ) as a measure of psychic distress of a clinically relevant nature. We found that GHQ scores are positively related to both the PDI and the LSHS-R scores, but the GHQ did not act as a mediator in the links between the 2 psychosis-proneness measures. Conversely, the LSHS-R scores fully mediated the links between GHQ and PDI scores. It can be argued that hallucination proneness and psychosis proneness do not overlap in the nonclinical population but can both cause distress separately.
尽管有证据表明，类似妄想或幻觉体验的报告可预测精神病谱系中精神障碍的未来发展，但这类异常主观体验在普通人群中的确切性质仍存在争议。我们使用彼得斯等人的妄想量表（PDI）和意大利版修改后的劳内 - 斯莱德幻觉量表（LSHS - R），对从正常人群中抽取的250名男女受试者的这些体验的多维性进行了调查，并使用一般健康问卷（GHQ）作为具有临床相关性的心理困扰的衡量标准。我们发现，GHQ得分与PDI和LSHS - R得分均呈正相关，但GHQ在两种精神病易感性测量之间的联系中并未起到中介作用。相反，LSHS - R得分完全介导了GHQ与PDI得分之间的联系。可以认为，在非临床人群中，幻觉易感性和精神病易感性并不重叠，但两者均可分别导致困扰。
