背景资料：考虑到冲动性和自杀倾向的实质异质性，需要增加研究这些变量之间关系的特异性。自杀倾向的一个方面，可能是特别重要的预测未来的风险在那些最近的自杀企图是自我感知的可能性，使未来的企图（自杀可能性）。目前，人们对冲动性与自杀这一重要方面的关系知之甚少。我们研究了三个不同的冲动方面（即，方法：研究对象包括155名精神科住院患者，他们在最近的自杀企图后到一级创伤医院就诊。结构方程模型（SEM），其中人口统计学和临床的协变量被控制，进行检查是否每个冲动方面将唯一预测自杀likes.Results：缺陷的自杀可能性是唯一强大的预测自杀likes.Results，与协会持续后，占人口统计学和临床的协变量。局限性：研究的局限性在于研究的横断面设计和未知的自杀可能性预测效度。结论：这是一个初步的调查冲动因素与自杀可能性。本研究的临床意义表明，在识别和干预自杀高危患者时，自杀可能性和自杀可能性的缺陷可能是需要考虑的重要因素。
Background: Given the substantial heterogeneity of both impulsivity and suicidality, increased specificity in studying relations between these variables is needed. One aspect of suicidality that may be especially important for predicting future risk among those with a recent suicide attempt is self-perceived likelihood of making a future attempt (suicide likelihood). Presently, little is known about the extent to which impulsivity is related to this important aspect of suicidality. We examined whether three distinct impulsivity facets (i.e., deficits in conscientiousness, negative urgency, and sensation seeking) would differentially predict suicide likelihood.Methods: Participants included 155 psychiatric inpatients who presented to a Level-1 trauma hospital after a recent suicide attempt. Structural Equation Modeling (SEM), in which demographic and clinical covariates were controlled, was conducted to examine whether each impulsivity facet would uniquely predict suicide likelihood.Results: Deficits in conscientiousness was the only robust predictor of suicide likelihood, with an association that persisted after accounting for demographic and clinical covariates.Limitations: The cross-sectional design and unknown predictive validity of suicide likelihood are study limitations.Conclusion: This was a preliminary investigation of impulsivity facets with suicide likelihood. Clinical implications of this study suggest that deficits in conscientiousness and suicide likelihood may be important factors to consider when identifying and intervening with patients at high-risk for suicide.
