Background and Hypothesis Children who endorse psychotic-like experiences (PLEs) appear to be at a greater risk for suicidal ideation and behavior (SI/SB) compared to their peers who do not endorse PLEs. Despite evidence of differential relations among subtypes of PLEs and SI/SB, the research on which PLE subtypes produce the strongest associations remains mixed. Further, though there is evidence that general psychological distress may help explain the relation between PLEs and SI/SB, no research has investigated the role of distress specific to PLEs in this association. Study Design The present study sought to assess the associations among individual Prodromal Questionnaire-Brief Child Version (PQ-BC) items and SI/SB, as well as to explore the role of distress associated with PLEs as a mediator and/or moderator in a demographically diverse sample of children across the United States (N = 11 875). Study Results Results revealed that individual items of the PQ-BC may be differentially predictive of lifetime SI (ßs = 0.000–0.098) and SB (ßs=0.002–0.059), even when controlling for sociodemographic variables, internalizing symptoms, and traumatic experiences, with particularly strong associations observed among items indexing thought control, auditory hallucinations, suspiciousness, and nihilistic thinking/dissociative experiences. Item 13, nihilistic thinking/dissociative experiences, displayed the strongest effect sizes. Findings from moderation and mediation models provided evidence consistent with distress as both a partial mediator and moderator of the relation between total PLEs and individual PQ-BC items with SI and SB. Conclusions Distress specific to PLEs may be an important modifiable risk factor to target in suicide assessment, prevention, and intervention efforts.

深入研究美国儿童精神病样经历与自杀意念和行为之间的关系

背景和假设 与不认可类似精神病经历 (PLE) 的同龄人相比，认可类似精神病经历 (PLE) 的儿童出现自杀意念和自杀行为 (SI/SB) 的风险更大。尽管有证据表明 PLE 亚型和 SI/SB 之间存在差异关系，但关于哪些 PLE 亚型产生最强关联的研究仍然褒贬不一。此外，尽管有证据表明一般心理困扰可能有助于解释 PLE 和 SI/SB 之间的关系，但没有研究调查 PLE 特有的困扰在这种关联中的作用。研究设计本研究旨在评估个体前驱问卷-简短儿童版 (PQ-BC) 项目与 SI/SB 之间的关联，并探讨与 PLE 相关的痛苦作为中介和/或调节因素的作用。美国各地人口统计多样化的儿童样本 (N = 11 875)。研究结果结果显示，即使在控制社会人口统计学变量、内化症状和创伤经历的情况下，PQ-BC 的各个项目也可能对终生 SI (ßs = 0.000–0.098) 和 SB (ßs=0.002–0.059) 有差异性预测，在索引思想控制、幻听、多疑和虚无主义思维/分离体验的项目之间观察到特别强烈的关联。第 13 项，虚无主义思维/分离体验，显示出最强的效应量。调节和中介模型的研究结果提供了与痛苦相一致的证据，即作为总 PLE 与带有 SI 和 SB 的单个 PQ-BC 项目之间关系的部分中介和调节因素。结论 PLE 特有的痛苦可能是自杀评估、预防和干预工作中一个重要的可改变危险因素。
