Individuals with schizophrenia are at increased risk for suicide. However, much less is known about suicide risk among individuals with schizotypic features. To address this gap in the literature, the current report examines the relationship between positive schizotypy and suicide risk using five distinct samples. Each of these five studies addresses unique, but complementary, questions regarding the relationship between positive schizotypy and suicide risk. Studies 1 and 2 investigate the cross-sectional relationship between perceptual aberrations and suicidal ideation. Study 3 examines the relationship between suicidal ideation and multiple positive schizotypic features (perceptual aberrations, magical thinking, paranoia, and referential thinking). Study 4 investigates the long-term relationship between perceptual aberrations and suicide risk through a 17-year follow-up. Finally, Study 5 examines the specificity of our findings using a psychiatric control group. Results across all five studies support a relationship between suicide risk and positive schizotypy. Specifically, perceptual aberrations were associated with suicide risk both cross-sectionally and longitudinally. Results also suggest that individuals with positive schizotypic features have rates of suicidal ideation that are comparable to those with high negative affect and are significantly greater than healthy controls. Taken together, these findings establish an empirical connection between positive schizotypy and suicide risk, thus expanding the purview of the suicide risk construct.

使用五个不同的样本检查阳性精神分裂与自杀风险之间的关系。

精神分裂症患者自杀的风险增加。然而，人们对具有精神分裂特征的个体的自杀风险知之甚少。为了解决文献中的这一空白，本报告使用五个不同的样本研究了阳性精神分裂与自杀风险之间的关系。这五项研究中的每一项都解决了有关阳性精神分裂与自杀风险之间关系的独特但互补的问题。研究 1 和研究 2 调查了知觉失常与自杀意念之间的横向关系。研究 3 探讨了自杀意念与多种积极的精神分裂特征（知觉失常、魔法思维、偏执和参照思维）之间的关系。研究 4 通过 17 年的随访调查了知觉失常与自杀风险之间的长期关系。最后，研究 5 使用精神病学对照组检验了我们研究结果的特异性。所有五项研究的结果都支持自杀风险与阳性精神分裂之间的关系。具体来说，知觉失常在横向和纵向上都与自杀风险相关。结果还表明，具有阳性精神分裂特征的个体的自杀意念发生率与具有高负面影响的个体相当，并且显着高于健康对照。总而言之，这些发现在阳性精神分裂和自杀风险之间建立了实证联系，从而扩大了自杀风险构建的范围。（PsycInfo 数据库记录 (c) 2023 APA，
