The purpose of this study was to develop and test a model of high-lethality suicide attempts (HLSA) in individuals with Borderline Personality Disorder (BPD). An increased number of prior suicide attempts, substance use immediately prior to the attempt, and objective planning were proposed to lead directly to a HLSA, while aggression and impulsivity were hypothesized to lead indirectly to a HLSA through their associations with prior attempts. Path analysis revealed a revised model in which impulsivity was found to be significantly associated with both the lethality of the most recent attempt and the number of prior attempts. These results are discussed in terms of trait and crescendo models of suicidal behavior and their implications for suicide risk assessment among individuals with BPD.
本研究旨在为边缘型人格障碍（BPD）患者建立并检验高致死性自杀尝试（HLSA）模型。研究提出，既往自杀尝试次数较多、尝试前即刻使用物质以及客观计划被假设直接导致 HLSA，而攻击性和冲动性则被假设通过与既往尝试的关联间接导致 HLSA。路径分析显示，修订后的模型发现冲动性与最近一次尝试的致命性和既往尝试次数均显著相关。这些结果将根据自杀行为的特质和渐强模型及其对 BPD 患者自杀风险评估的影响进行讨论。
