Unusual subjective experiences are relatively common in the general population and have been associated with an increased level of vulnerability to psychosis. The current study aimed to a) determine the distribution of hallucination-like experiences (HLEs) in a community sample of young adults, b) investigate their dimensional subtypes, and c) test the association of HLEs with indicators of poor mental health. Four hundred thirty-seven participants (men, 41%) completed a battery of questionnaires including the 16-item Launay-Slade Hallucination Scale (LSHS), the 12-item General Health Questionnaire (GHQ-12) and the 21-item Peters et al. Delusions Inventory (PDI). The LSHS correlated significantly with GHQ-12 and PDI. Individuals with higher levels of psychological distress were found to report higher frequencies of the HLEs compared with those in the reference range. Exploratory factor analysis of LSHS produced a four-factor solution: a) "auditory and visual HLEs," b) "multisensory HLEs," c) "intrusive thoughts," and d) "vivid daydreams." The current results provide further support for the multidimensional nature of hallucination proneness in the general population and indicate that some HLEs (particularly those related to intrusiveness of thought) are associated with a lower level of perceived well-being.
异常主观体验在普通人群中相对常见，且与患精神病的易感性增加有关。本研究旨在：a）确定年轻成年人社区样本中幻觉样体验（HLEs）的分布情况；b）调查其维度亚型；c）测试HLEs与心理健康不良指标之间的关联。437名参与者（男性占41%）完成了一系列问卷，包括16项的劳内-斯莱德幻觉量表（LSHS）、12项的一般健康问卷（GHQ - 12）以及21项的彼得斯等人的妄想量表（PDI）。LSHS与GHQ - 12和PDI显著相关。与处于参考范围的个体相比，心理困扰程度较高的个体报告的HLEs频率更高。对LSHS进行探索性因素分析得出了一个四因素解决方案：a）“听觉和视觉HLEs”；b）“多感官HLEs”；c）“侵入性思维”；d）“生动的白日梦”。当前结果为普通人群中幻觉易感性的多维性质提供了进一步支持，并表明一些HLEs（特别是那些与思维侵入性相关的）与较低的幸福感水平相关。
