Abstract

Background: In schizophrenia, the relationship between suicide and cognition is unclear. We aimed to assess cognitive functions and insight in schizophrenia patients with and without suicide attempts.

Methods: In our study consisting of 77 patients, 36 of the patients had attempted suicide at least once in their lives and the remaining 41 had never attempted suicide. Sociodemographic data scale, Beck Cognitive Insight Scale, and Cambridge Neurophysiological Assessment Battery were applied.

Results: In this study, patients with schizophrenia who attempted suicide had higher Beck Cognitive Insight Scale self-reflectiveness scores (P = .004), lower Beck Cognitive Insight Scale self-certainty scores (P = .040), and higher Beck Cognitive Insight Scale total score (P = .004). Delay aversion (P = .003) and risk-taking scores (P = .044) of Cambridge Neurophysiological Assessment Battery Cambridge gambling task were higher in patients who attempted suicide. In logistic regression analysis, as independent factors, the number of hospitalizations increased the risk of suicide 1.5 times per hospitalization (P = .021), Cambridge gambling task delay aversion increased the risk of suicide 8.4 times per score (P = .044), and the Beck Cognitive Insight Scale self-certainty score was shown as the factor that decreased the risk of suicide by 0.78 times (P = .024).

Conclusion: The causes of suicide attempts in schizophrenia still preserve its uncertainty. Our results proposed a statistically significant relationship between cognitive insight and increased suicide attempts. This study also sustains that cognitive impulsivity is associated with suicidal behavior in patients with schizophrenia.

精神分裂症患者自杀行为、神经认知功能和洞察力之间的关系。

背景：精神分裂症患者自杀与认知之间的关系尚不明确。我们旨在评估有自杀企图和没有自杀企图的精神分裂症患者的认知功能和洞察力：在我们的研究中，共有 77 名患者，其中 36 人一生中至少自杀未遂过一次，其余 41 人从未尝试过自杀。研究采用了社会人口学数据量表、贝克认知洞察力量表和剑桥神经生理学评估测试：在这项研究中，自杀未遂的精神分裂症患者的贝克认知洞察力量表自我反思性得分较高（P = .004），贝克认知洞察力量表自我确定性得分较低（P = .040），贝克认知洞察力量表总分较高（P = .004）。自杀未遂患者在剑桥神经生理学评估测试（Cambridge Neurophysiological Assessment Battery Cambridge gambling task）中的延迟厌恶（P = .003）和冒险得分（P = .044）更高。在逻辑回归分析中，作为独立因素，住院次数会使每次住院的自杀风险增加1.5倍（P = .021），剑桥赌博任务延迟厌恶会使每次得分的自杀风险增加8.4倍（P = .044），而贝克认知洞察力量表自我确定性得分则会使自杀风险降低0.78倍（P = .024）：结论：精神分裂症患者自杀未遂的原因仍具有不确定性。我们的研究结果表明，认知洞察力与自杀企图增加之间存在统计学意义上的显著关系。本研究还证实，认知冲动与精神分裂症患者的自杀行为有关。

期刊介绍： European Planning Studies provides a forum for ideas and information about spatial development processes and policies in Europe. The journal publishes articles of a theoretical, empirical and policy-relevant nature and is particularly concerned to integrate knowledge of processes with practical policy proposals, implementation and evaluation. Articles of particular interest to the journal focus upon specific spatial development problems, as well as emerging explanations of new urban, regional, national or supranational developmental tendencies. Country-specific, region-specific or locality-specific issues are focused upon, although comparative analysis is of especial value.
