Background: This study aims to identify the main predictive factors that allow for the recognition of adolescents with a higher risk of re-attempting suicide. Method: A longitudinal 12-month follow-up design was carried out in a sample of 533 Spanish adolescents between 12 and 17 years old. The data collection period comprised September 2013 to November 2016, including a one-year follow-up after hospital discharge. Results: A statistically significant regression model was obtained to predict suicide re-attempt at 12-months’ follow-up (χ2 = 34.843; p < 0.001; Nagelkerke R2 = 0.105), including personal history of self-injury (OR = 2.721, p < 0.001, 95% CI [1.706, 4.340]) and age (OR = 0.541, p = 0.009, 95% CI [0.340, 0.860]), correctly classifying 82.6% of the sample. Our results show that having a personal history of self-injury and being younger than 14 years old were predictors of suicide re-attempt during the first year after an adolescent’s first admission to emergency services. Conclusions: Considering these factors could contribute to the design of more tailored and effective interventions to prevent suicidal behavior in adolescents at high risk of re-attempting suicide.
本研究旨在确定能够识别自杀未遂风险较高的青少年的主要预测因素。
对 533 名 12-17 岁的西班牙青少年进行了为期 12 个月的纵向随访设计。数据收集时间为 2013 年 9 月至 2016 年 11 月，包括出院后 1 年的随访。
得出了一个预测自杀再尝试的统计学上显著的回归模型（χ2 = 34.843；p < 0.001；Nagelkerke R2 = 0.105），包括个人自伤史（OR = 2.721，p < 0.001，95%CI [1.706, 4.340]）和年龄（OR = 0.541，p = 0.009，95%CI [0.340, 0.860]），正确分类了 82.6%的样本。结果表明，有个人自伤史和年龄小于 14 岁是青少年首次就诊后第一年自杀再尝试的预测因素。
考虑这些因素有助于设计更有针对性和有效的干预措施，以预防有自杀未遂风险的青少年再次出现自杀行为。
