Abstract

Impulsivity has been conceptualized as influencing the expression of suicidal behavior. Adolescence is a developmental period characterized both by a relatively high rate of suicide attempts and a high level of impulsivity. The current study examined two behavioral measures (delay reward and disinhibition) and one self-report measure of impulsivity among girls with suicide attempt histories. Girls with multiple suicide attempts performed more impulsively on measures of delayed reward, and had higher self-ratings of depression and aggression than girls with either one or no suicide attempts. The multiple attempter girls' preference for immediate gratification may directly increase vulnerability to suicidal acts in the context of distressing states or indirectly increase risk by creating poor life experience over time.

摘要

冲动性被认为会影响自杀行为的表现。青春期是一个发展阶段,其特点是自杀未遂率相对较高,冲动水平也很高。本研究在有自杀未遂史的女孩中检查了两种行为测量方法(延迟奖励和抑制解除)和一种冲动的自我报告测量方法。有多次自杀尝试的女孩在延迟奖励测量中表现出更冲动的行为,并且自我报告的抑郁和攻击性评分高于只有一次或没有自杀尝试的女孩。多次尝试自杀的女孩对即时满足的偏好可能会直接增加在痛苦状态下自杀行为的脆弱性,或者通过随着时间的推移创造较差的生活体验间接增加风险。
