OBJECTIVE Suicide remains a leading cause of death in the United States, and recent reports have suggested the suicide rate is increasing. One of the most robust predictors of future suicidal behavior is a history of attempting suicide. Despite this, little is known about the factors that reduce the likelihood of reattempting suicide. This study compares theoretically derived suicide risk indicators to determine which factors are most predictive of future suicide attempts. METHOD We used data from a randomized, controlled trial comparing 3 forms of dialectical behavior therapy (DBT; Linehan et al., 2015). Participants (N = 97, mean age = 30.3 years, 100% female, 71% White) met criteria for borderline personality disorder and had repeated and recent self-injurious behavior. Assessments occurred at 4-month intervals throughout 1 year of treatment and 1 year of follow-up. Time-lagged generalized linear mixed models (GLMMs) were used to evaluate relationship satisfaction, emotion dysregulation, and coping styles as predictors of suicide attempts. RESULTS Both univariate and multivariate models suggested that higher between-person variance in problem-focused coping and lack of access to emotion regulation strategies were weakly associated with additional suicide attempts over the 2-year study. Within-person variance in the time-lagged predictors was not associated with subsequent suicide attempts. CONCLUSIONS Among individuals with a recent suicide attempt, problem-focused coping and specific deficits in emotion regulation may differentiate those likely to reattempt from those who stop suicidal behavior during and after psychotherapy. These results suggest that treatments for recent suicide attempters should target increasing problem-focused coping and decreasing maladaptive emotion regulation skills.

对自杀行为周期进行建模：了解边缘性人格障碍患者的自杀尝试和自杀历史。

目的自杀仍然是美国的主要死亡原因，最近的报告表明自杀率正在上升。未来自杀行为最强有力的预测因素之一是自杀未遂的历史。尽管如此，对于减少重新尝试自杀的可能性的因素知之甚少。这项研究比较了理论上得出的自杀风险指标，以确定哪些因素最能预测未来的自杀尝试。方法我们使用来自一项随机对照试验的数据，比较了三种形式的辩证行为疗法（DBT； Linehan等人，2015）。参与者（N = 97，平均年龄= 30.3岁，女性为100％，白人为71％）符合边缘性人格障碍的标准，并且有反复和近期的自残行为。在治疗1年和随访1年中，每4个月进行一次评估。时滞广义线性混合模型（GLMM）用于评估关系满意度，情绪失调和应对方式，作为自杀未遂的预测指标。结果单变量和多变量模型均表明，在为期两年的研究中，针对问题的应对中较高的人际差异和缺乏情绪调节策略的获取与自杀未遂的关联性较弱。时间滞后预测因素的人际差异与随后的自杀未遂无关。结论在最近有自杀企图的个人中，以问题为中心的应对方法和情绪调节方面的特定缺陷可能使那些可能重新尝试的人与那些在心理治疗期间和之后停止自杀行为的人有所区别。这些结果表明，针对近期自杀未遂者的治疗应针对增加以问题为中心的应对方法和降低适应不良的情绪调节技能。（PsycINFO数据库记录（c）2020 APA，保留所有权利）。
