目的：在社区样本中进行的研究表明，精神病样经历在普通人群中很常见；有人认为，这种经历要么是正常人格的变异，要么是精神障碍易感性的不同表现。本研究的目的是确定是否可以在社区青少年和年轻人样本中识别不同的PLE亚型，并调查特定的PLE亚型是否比其他亚型更容易与心理社会困难(即苦恼、抑郁和功能低下)相关。方法：1882名来自高中和大学的学生参加了一项横断面多点调查，使用社区心理体验评估(CAPE)的积极量表测量PLE，II)使用CAPE抑郁和苦恼子量表测量抑郁和苦恼，以及III)使用一般健康问卷-12测量功能。结果：PLE分为4种亚型：离奇经历(BE)、知觉异常(PA)、受迫害念头(PI)和浮夸(GR)。间歇性的、不常见的精神病经历是常见的，而频繁的经历则不常见。BE和PI与痛苦、抑郁和功能低下密切相关。PA和GR与这些变量的相关性较小。结论：在这个大样本中发现了不同的PLE亚型，证实了我们以前的研究结果。这些亚型似乎具有不同的精神病理学意义，因此可能表明患严重精神障碍的风险水平不同，这表明将PLE定义为同质实体具有误导性。(C)2010 Elsevier B.V.保留所有权利，
Objective: Studies conducted in community samples indicate that psychotic-like experiences (PLEs) are common in the general population; it has been suggested that such experiences are either variations in normal personality or different expressions of vulnerability to psychotic disorders. The aim of this study was to determine whether different subtypes of PLEs could be identified in a community sample of adolescents and young adults, and to investigate whether particular subtypes of PLEs were more likely to be associated with psychosocial difficulties, i.e. distress, depression and poor functioning, than other subtypes.Method: 1882 students from high schools and universities participated in a cross-sectional multisite survey that measured i) PLEs using the Positive Scale of the Community Assessment of Psychic Experiences (CAPE), ii) depression and distress using the CAPE Depression and Distress Subscales, and iii) functioning using the General Health Questionnaire-12. Factor analysis was conducted to identify any subtypes of PLEs.Results: Four subtypes of PLEs were identified: bizarre experiences (BE), perceptual abnormalities (PA), persecutory ideas (PI) and grandiosity (GR). Intermittent, infrequent psychotic experiences were common, whereas frequent experiences were not. BE and PI were strongly associated with distress, depression and poor functioning. PA and GR were associated with these variables to a lesser degree.Conclusions: Different subtypes of PLEs were identified in this large sample, confirming the findings of our previous studies. These subtypes seem to have different psychopathological meaning and may therefore indicate different levels of risk of severe psychiatric disorders, which suggests it is misleading to define PLEs as a homogenous entity.
