There are conflicting results on the relationship between neuroticism and suicidal ideation in community population. The objectives of this study were to estimate the magnitude and direction of the association between neuroticism and suicide ideation, and to analyze the influence of moderator variables on the effect size.
A systematic review and a meta-analysis were carried out. The search for studies was conducted in PubMed/MEDLINE, IME, Lilacs, CINAHL, and EMBASE, until January 2015. A manual search was also carried out and main researchers were contacted. The inclusion criteria were: (a) studies of the association between neuroticism and suicidal ideation; (b) observational and descriptive studies; (c) studies carried out with community population over 18 years; (d) in any geographic region; and (e) written in English, Spanish, French, Portuguese or Italian. The random-effects model was applied to obtain the mean effect size and to explore moderators.
Thirteen articles focused on the association between neuroticism and suicide ideation were included in the meta-analysis. The mean effect size was r+ = 0.446 (IC 95%: 0.266-0.595). Publication bias was discarded as a threat against the validity of the results. A predictive model was stablished with two moderator variables: gender and type of self-report to measure neuroticism.
Neuroticism can be considered as a risk factor for suicide ideation. This result is important to prevent both suicidal ideation and suicide behavior.
关于社区人群中神经质与自杀意念之间的关系，研究结果存在冲突。本研究的目的是估计神经质与自杀意念之间关联的大小和方向，并分析调节变量对效应量的影响。
进行了一项系统评价和荟萃分析。截至2015年1月，在PubMed/MEDLINE、IME、Lilacs、CINAHL和EMBASE中检索研究。还进行了手动检索并联系了主要研究人员。纳入标准为：(a) 关于神经质与自杀意念之间关联的研究；(b) 观察性和描述性研究；(c) 对18岁以上社区人群开展的研究；(d) 在任何地理区域；以及(e) 用英语、西班牙语、法语、葡萄牙语或意大利语撰写。应用随机效应模型来获得平均效应量并探索调节因素。
荟萃分析纳入了13篇关注神经质与自杀意念之间关联的文章。平均效应量为r+ = 0.446（95%置信区间：0.266 - 0.595）。排除了发表偏倚对结果有效性的威胁。建立了一个预测模型，其中有两个调节变量：性别和测量神经质的自我报告类型。
神经质可被视为自杀意念的一个风险因素。这一结果对于预防自杀意念和自杀行为都很重要。
