While previous studies have examined motivational aspects of self-directed violence, few studies have included specific motivations in predictive models for future suicide attempts. The current study utilized a sample of 160 individuals treated in an acute emergency setting following a suicide attempt who completed an interview battery that included an assessment of functional aspects of the index suicide attempt. A follow-up interview was conducted at 6 months to ascertain subsequent suicide attempts. The functional domains of suicide attempts were labeled as reduction-of-distress, communication, perceived better alternative to living, and self-loathing. Above and beyond other known risk factors, including history and highest lethality of previous self-injury, suicide attempts that served a communication function (OR = 0.18, p = .02, CI = 0.04, 0.73) and higher ratings of clinical dysfunction (OR = 3.41, p = .05, CI = 1.02, 11.36) were associated with a significant reduction in likelihood to engage in a suicide attempt during the 6-month follow-up window. Including the perceived effectiveness of the index suicide attempt in getting one's needs met strengthened the overall model predicting a suicide attempt in the follow-up window and was an independent risk factor above and beyond other variables in the model OR = 1.75, p = .04, CI = 1.02, 3.01). Assessment of functional aspects of suicide attempt is feasible and may improve formulation of risk in a population where typical risk factors for suicide are ubiquitous.
虽然先前的研究已经考察了自我导向暴力的动机方面,但很少有研究将特定动机纳入未来自杀未遂的预测模型中。本研究以160名在自杀未遂后于急性紧急情况下接受治疗的个体为样本,这些个体完成了一系列访谈,其中包括对此次自杀未遂功能性方面的评估。在6个月时进行了一次随访访谈,以确定随后的自杀未遂情况。自杀未遂的功能领域被标记为减轻痛苦、沟通、认为有更好的生存选择以及自我厌恶。除了其他已知的风险因素,包括既往自我伤害的历史和最高致死率外,具有沟通功能的自杀未遂(比值比=0.18,p=0.02,可信区间=0.04,0.73)和更高的临床功能障碍评分(比值比=3.41,p=0.05,可信区间=1.02,11.36)与6个月随访期内自杀未遂可能性的显著降低相关。将此次自杀未遂在满足自身需求方面的感知有效性纳入其中,增强了预测随访期内自杀未遂的整体模型,并且是该模型中除其他变量之外的一个独立风险因素(比值比=1.75,p=0.04,可信区间=1.02,3.01)。对自杀未遂功能性方面的评估是可行的,并且在自杀典型风险因素普遍存在的人群中可能会改善风险评估。
