A history of multiple suicide attempts conveys greater risk for suicide than a single attempt. Impulsivity may partially explain the association between multiple attempts and increased risk. We examined trait impulsivity, ability to engage in goal-directed behaviors, and impulse control among psychiatrically hospitalized United States military personnel and their dependents. Individuals with a history of multiple versus single attempts had significantly higher motor impulsivity, indicating spur of the moment action. Providers are encouraged to directly assess and treat motor impulsivity among suicidal individuals. Further research should explore whether motor impulsivity is a mechanism of change in psychosocial suicide prevention interventions.
有多次自杀企图的病史比单次自杀企图传达出更大的自杀风险。冲动性可能部分解释了多次尝试与风险增加之间的关联。我们在美国军事人员及其家属中检查了特质冲动性、从事目标导向行为的能力和冲动控制。与单次尝试相比，有多次尝试病史的个体表现出更高的运动冲动性，表明瞬间的行动。鼓励提供者在自杀个体中直接评估和治疗运动冲动性。进一步的研究应该探索运动冲动性是否是心理社会自杀预防干预措施改变的机制。
