背景：自杀行为是一个重要的公共卫生问题，但人们对导致或阻碍行为实施（自杀未遂）的因素知之甚少。目的：利用自杀行为综合动机-意志（IMV）模型（2011），本研究考察了与自杀想法（意念）相关的因素和与自杀实施（企图）相关的因素。在多变量背景下，预测与观念形成相关的因素（动机因素）将不同于那些控制行为表现的因素（意志调节因素）。方法：健康成年人（N = 1, 288）完成了一项匿名自我报告调查。分析比较了三组：自杀未遂者 (n=230)、自杀者 (n=583) 和没有任何自杀史的人 (n=475)。 结果：自杀未遂者与自杀意念者在所有意志因素（对死亡的恐惧、冲动和自杀行为的暴露）上都存在差异，但不适耐受性除外。与想法者相比，尝试者更有可能有自残或企图自杀的家庭成员和亲密朋友，并且更加冲动和对死亡无所畏惧。相反，两个自杀组在与自杀死亡想法的发展相关的任何变量（动机因素）上没有差异。局限性：这是一项基于自我报告措施的横断面研究。结论：区分自杀意念者和自杀企图者的进一步研究工作对于干预和治疗方法的发展至关重要。 (C) 2015 Elsevier B.V. 保留所有权利。
Background: Suicidal behaviour is a significant public health concern, yet little is known about the factors that enable or impede behavioural enactment (engaging in a suicide attempt).Aims: Drawing on the Integrated Motivational-Volitional (IMV) Model of Suicidal Behaviour (2011), this study examined the factors associated with having thoughts of suicide (ideation) versus those associated with suicide enaction (attempts). Within a multivariate context, it was predicted that the factors associated with ideation formation (motivational factors) would be distinct from those factors which governed behavioural enaction (volitional moderators).Method: Healthy adults (N=1, 288) completed an anonymous self-report survey. Analyses compared three groups: suicide attempters (n=230), suicide dleators (n=583), and those without any suicide history (n=475).Results: Suicide attempters differed from suicide ideators on all volitional factors (fearlessness about death, impulsivity, and exposure to suicidal behaviour), with the exception of discomfort tolerance. Compared to ideators, attempters were more likely to have a family member and close friend who had self-injured or attempted suicide, and were more impulsive and fearless about death. Conversely, the two suicide groups did not differ on any of the variables (motivational factors) associated with the development of thoughts of death by suicide.Limitations: This is a cross-sectional study based on self-report measures.Conclusions: Further research efforts to distinguish between suicide ideators and suicide attempters is crucial to inform the development of intervention and treatment approaches.
