Suicide attempt is a risk factor for suicide. To investigate trait impulsivity among suicide attempters, 93 attempters admitted to an emergency department and 113 healthy controls were evaluated using the Japanese version of the Barratt Impulsiveness Scale (BIS-11J). Impulsivity was analyzed in relation to clinical data in the attempters. Total BIS-11J, attention impulsiveness, and motor impulsiveness scores were significantly higher in the attempters than in the controls. Both total BIS-11J and non-planning impulsiveness scores were significantly higher in attempters with schizophrenia and other psychotic disorders among the diagnostic groups. Control of impulsivity should be considered as one of the targets for suicide prevention.
自杀企图是自杀的一个风险因素。为了调查自杀者的特质冲动性，我们使用巴瑞特冲动量表（BIS-11J）的日文版评估了 93 名到急诊科就诊的自杀未遂者和 113 名健康对照者。在这些未遂者中，冲动性与临床数据相关进行了分析。在所有诊断组中，与对照组相比，未遂者的 BIS-11J 总分、注意力冲动性和运动冲动性得分显著更高。在诊断为精神分裂症和其他精神病障碍的患者中，BIS-11J 总分和非计划性冲动性得分均显著更高。控制冲动性应被视为预防自杀的目标之一。
