People with psychotic symptoms are reported to have a characteristic reasoning style in which they jump to conclusions (JTC). The aims of this research were threefold. The first was to establish how prevalent this style is in people with first-episode psychosis. The second was to examine the specificity of JTC to delusions. The third was to examine explanatory factors that may account for the JTC style. This was investigated by attempting to replicate, with a large sample, previous studies indicating that JTC is associated with specific psychotic and non-psychotic symptoms and processes.
Seventy-seven service users were recruited from a first-episode service and completed measures of reasoning and psychotic and non-psychotic symptomatologies. A well-established criterion was used to compare the JTC performance of those people with and without JTC.
JTC was present in over 40% of the sample, which is consistent with previous studies of people with long-standing psychotic symptoms. Unlike previous research, no strong associations were found in relation to symptoms and other processes.
JTC is a phenomenon common in many people in first-episode services. In this large cohort sample, no clear associations with symptoms or other psychological processes were evident. Hence, the reason people JTC is still unclear.
有报道称，精神病症状患者具有一种独特的推理风格，即仓促下结论（JTC）。本研究旨在实现三个目标。首先，确定首发精神病患者中这种推理风格的普遍程度。其次，研究 JTC 对妄想的特异性。第三，研究可以解释 JTC 风格的因素。通过尝试复制先前的研究，该研究表明 JTC 与特定的精神病和非精神病症状和过程有关，从而达到了这一目标。
从首发服务中招募了 77 名服务使用者，并对他们的推理能力以及精神病和非精神病症状进行了评估。使用了一个既定的标准来比较有 JTC 和无 JTC 的人的 JTC 表现。
超过 40%的样本存在 JTC，这与以前对长期存在精神病症状的人群的研究一致。与以往的研究不同，在与症状和其他过程的关系上没有发现强烈的关联。
JTC 是首发服务中许多人常见的现象。在这个大型队列样本中，没有明显的症状或其他心理过程的关联。因此，人们仓促下结论的原因仍不清楚。
