Although nonsuicidal self-injury (NSSI) is known to be associated with increased risk of death by suicide and suicide attempts, minimal research has focused on comparing recent suicide attempters with and without NSSI on suicide attempt characteristics (frequency and severity of suicide attempts). Understanding how NSSI impacts suicide attempt characteristics can help providers to enhance their assessment and treatment strategies so as to prevent future suicidal behaviors.
The present study investigated the extent to which a history of NSSI was related to the frequency and severity of suicide attempts in a sample of recent suicide attempters.
Participants included 171 adult patients who presented to the hospital within 24 hr of a suicide attempt. Information about their suicide attempts and NSSI was gathered using self-report questionnaires and interviews.
Suicide attempters with a history of NSSI reported significantly more suicide attempts and more suicide attempts requiring medical attention, after controlling for important clinical covariates.
NSSI was uniquely associated with suicide attempt characteristics, highlighting the importance of NSSI in suicide assessment, prevention, and treatment efforts.
尽管已知非自杀性自伤（NSSI）与自杀死亡和自杀未遂风险增加有关，但极少有研究关注比较近期有和没有NSSI的自杀未遂者在自杀未遂特征（自杀未遂的频率和严重程度）方面的差异。了解NSSI如何影响自杀未遂特征有助于医护人员改进评估和治疗策略，从而预防未来的自杀行为。
本研究调查了在近期自杀未遂者样本中，NSSI史与自杀未遂频率和严重程度的相关程度。
参与者包括171名成年患者，他们在自杀未遂后24小时内入院。通过自我报告问卷和访谈收集了他们自杀未遂及NSSI的信息。
在控制了重要的临床协变量后，有NSSI史的自杀未遂者报告的自杀未遂次数显著更多，且需要医疗救治的自杀未遂次数也更多。
NSSI与自杀未遂特征存在独特关联，凸显了NSSI在自杀评估、预防和治疗工作中的重要性。
