Although a history of a suicide attempt is the strongest predictor of future suicide attempts, not all adolescents who make an attempt engage in repetitive suicidal behavior. The present study sought to determine whether certain characteristics of a first suicide attempt (e.g., age of first attempt, method of attempt used, intent seriousness, medical lethality, and receipt of treatment after attempt) can distinguish between adolescents who make single versus multiple suicide attempts. Adolescents (N = 95) who were psychiatrically hospitalized and their guardian completed a diagnostic interview to gather information on all lifetime suicide attempts. A multivariate hierarchical logistic regression was conducted, predicting single attempt versus multiple attempt status. Of the first-attempt characteristics examined, only age of first attempt, OR = 0.33, 95% CI [0.17-0.63], p = .001, and receipt of treatment following attempt, OR = 0.28, 95% CI [0.09-0.88], p = .028, significantly distinguished SA vs. MA status, even after controlling for current age and depression at the time of first attempt. Female and White participants were overrepresented in this sample, which limits generalization to more heterogenous and diverse samples. The cross-sectional nature of data introduces the potential for retrospective recall bias. Younger age of first attempt and lack of receipt of mental health treatment following a first attempt were associated with multiple attempt status. These findings highlight the importance of early mental health screening, parental psychoeducation, and linkage to mental health care after a suicide attempt.
虽然自杀未遂史是未来自杀未遂的最强预测因素,但并非所有尝试自杀的青少年都会重复出现自杀行为。本研究旨在确定首次自杀尝试的某些特征(例如,首次尝试的年龄、尝试使用的方法、意图严重程度、医学致死性以及尝试后接受的治疗)是否可以区分单次和多次自杀尝试的青少年。接受精神科住院治疗的青少年(N=95)及其监护人完成了一项诊断访谈,以收集所有一生中自杀尝试的信息。进行了多变量分层逻辑回归,以预测单次尝试与多次尝试的状态。在所检查的首次尝试特征中,只有首次尝试的年龄,OR=0.33,95%CI [0.17-0.63],p=0.001,以及尝试后接受治疗,OR=0.28,95%CI [0.09-0.88],p=0.028,即使在控制了首次尝试时的当前年龄和抑郁程度后,也能显著区分 SA 与 MA 状态。该样本中女性和白人参与者的代表性过高,这限制了对更多异质和多样化样本的推广。数据的横断面性质引入了回顾性回忆偏倚的可能性。首次尝试的年龄较小和首次尝试后未接受心理健康治疗与多次尝试状态有关。这些发现强调了早期心理健康筛查、父母心理教育以及在自杀尝试后与心理健康护理的联系的重要性。
