This study investigated the effects of the bias known as jumping to conclusions (JTC) on objective functional outcomes as well as subjective assessments of quality of life (QoL) and personal recovery among a sample of patients diagnosed with schizophrenia. Specifically, this study assessed the variables of JTC, psychiatric symptoms, neurocognitive functioning, objective interpersonal and daily activities, vocational domains, subjective QoL, and personal recovery among 94 participants. Results showed that those in the JTC group had significantly lower neurocognitive and functional outcomes (moderate effect sizes); however, subjective measures such as QoL and personal recovery did not differ significantly according to JTC (small effect sizes). After adjusting for attributes, there were no statistically significant differences, but the JTC group demonstrated lower overall functional outcomes and higher individual recovery, each with a moderate effect size. This 'trade-off' is not evidence-guaranteed, and further research is recommended to examine the relationship between social functioning and personal recovery in people with JTC bias.
本研究调查了被称为“急于下结论”（JTC）的偏差对确诊为精神分裂症患者样本的客观功能结局以及生活质量（QoL）主观评估和个人康复的影响。具体而言，本研究评估了94名参与者的JTC、精神症状、神经认知功能、客观人际和日常活动、职业领域、主观QoL和个人康复等变量。结果显示，JTC组的神经认知和功能结局显著更低（效应量中等）；然而，QoL和个人康复等主观指标根据JTC并无显著差异（效应量小）。在对属性进行调整后，没有统计学上的显著差异，但JTC组的总体功能结局更低，个人康复程度更高，各有中等效应量。这种“权衡”并无证据保证，建议进一步研究以检验存在JTC偏差的人群中社会功能与个人康复之间的关系。
