There is an increasing body of evidence suggesting an association between early adverse events and an increased prevalence of sub-clinical psychotic phenomena. These 'schizotypal' beliefs and experiences have been associated with a history of trauma, and are also recognised as a risk factor for the transition to psychosis. However, previous studies have not investigated the associations between specific types of adverse event and the distinct dimensions of such phenomena.
An internet questionnaire produced three groups of participants who had suffered discrete forms of childhood abuse.
Individuals who had suffered physical or sexual abuse exhibited higher levels of paranoia/suspiciousness and unusual perceptual experiences, but not magical thinking. Individuals who had suffered emotional abuse did not show higher scores within any of these three measures of schizotypy.
The results suggest the need for further research to improve the specificity of the identification of individuals who may be at risk of a transition to psychosis.
越来越多的证据表明早期不良事件与亚临床精神病性现象患病率增加之间存在关联。这些“分裂型”信念和经历与创伤史有关，也被认为是向精神病转变的一个危险因素。然而，以往的研究尚未调查特定类型的不良事件与此类现象的不同维度之间的关联。
通过互联网问卷招募了三组曾遭受不同形式童年虐待的参与者。
遭受身体虐待或性虐待的个体表现出更高水平的偏执/猜疑和异常感知体验，但没有表现出神奇思维。遭受情感虐待的个体在这三种分裂型特质测量中的任何一项上都没有表现出更高的分数。
研究结果表明需要进一步研究，以提高识别可能有向精神病转变风险个体的特异性。
