Background: Psychosis is a significant, yet understudied, risk factor for suicide. There has yet to be a systematic investigation examining the rate and predictors of inclusion of psychotic disorders or symptoms in suicide-focused trials. Aim: Our aim was to conduct a systematic review of inclusion/exclusion of psychosis in studies with suicidal ideation or behavior as a primary endpoint, rate of inclusion across intervention type and other characteristics, and criteria used to exclude psychosis and accompanying rationale. Method: A literature search was conducted using PubMed, Cochrane Library, and PsycInfo to identify relevant articles published between 2000 and 2018. Statements regarding inclusion/exclusion were codified by authors. Results: Out of 122 studies selected, 75 (61.5%) excluded individuals with psychosis. This rate varied by intervention and sample size, but not by year of study or country of origin. Only 9% provided a rationale for psychosis exclusion. Limitations: Minimal reporting of participants' diagnosis in studies disallowed analysis of the rate of inclusion of psychosis in samples. Conclusion: Three out of five trials with suicide-related primary outcomes excluded psychosis; thus, people with psychosis are poorly represented in suicide-specific studies. This disparity could be remedied by either adapting protocols to include people with psychosis or developing new, tailored treatments.

对自杀特定临床试验中纳入精神病患者的系统评价。

背景:精神病是自杀的重要但尚未充分研究的危险因素。尚未有系统的调查来研究以自杀为中心的试验中精神病或症状包括率和预测因素。目的:我们的目的是对以自杀意念或行为为主要终点的研究中精神病的纳入/排除进行系统回顾,涵盖干预类型和其他特征的纳入率,以及排除精神病的标准和伴随的理论依据。方法:使用PubMed,Cochrane Library和PsycInfo进行文献检索,以鉴定2000年至2018年之间发表的相关文章。作者对纳入/排除的陈述进行了编纂。结果:在122项研究中,有75例(61.5%)排除了精神病患者。该比率随干预和样本量的不同而变化,但不受研究年份或原籍国的影响。只有9%的人提供了排除精神病的理由。局限性:在研究中很少报告参与者的诊断,因此无法分析样本中精神病的纳入率。结论:五分之三的与自杀有关的主要结局试验排除了精神病。因此,在专门针对自杀的研究中,精神病患者的代表性很低。可以通过调整方案以包括精神病患者或开发新的,量身定制的治疗方法来纠正这种差距。研究中的诊断无法分析样本中精神病的包含率。结论:五分之三的与自杀有关的主要结局试验排除了精神病。因此,精神病患者在针对自杀的研究中所占的比例很低。可以通过调整方案以包括精神病患者或开发新的,量身定制的治疗方法来纠正这种差距。研究中的诊断无法分析样本中精神病的包含率。结论:五分之三的与自杀有关的主要结局试验排除了精神病。因此,在专门针对自杀的研究中,精神病患者的代表性很低。可以通过调整方案以包括精神病患者或开发新的,量身定制的治疗方法来纠正这种差距。
