使用哥伦比亚自杀严重程度评定量表（C-SSRS），我们检查了过去一个月的自杀行为和短期自杀行为的意念在自杀高危青少年中的预测和增量预测效度。该研究于2014年在99名（49.7%）基线受访者中的85名青少年（90.6%为女性）中进行，他们参与了随访（85.9%）。所有的青少年都是从丹麦的一家专门的自杀预防诊所招募的。通过多变量logistic回归分析，我们检查了基线自杀行为是否预测了随后的自杀行为（任何类型的实际企图和自杀行为，包括准备行为、流产、中断和实际企图;平均随访80.8天，SD = 52.4）。此外，我们研究了自杀意念的严重程度和强度是否在基线自杀行为的基础上递增预测随访时的自杀行为。基线时的实际自杀企图强烈预测随访时的自杀企图。基线自杀意念的严重程度和强度并不能显著预测未来超过基线的实际尝试。自杀意念强度项目、威慑因素和持续时间分别是调整基线自杀企图和任何类型自杀行为后后续实际企图的显著预测因素。自杀意念的严重程度和强度，以及强度项目的频率、持续时间和威慑因素，都显著预测了随访时的任何类型的自杀行为，也在校正基线自杀行为后。本研究表明，C-SSRS自杀意念量表对高危青少年中任何类型的短期自杀行为的预测有效性增加。
Using the Columbia-Suicide Severity Rating Scale (C-SSRS), we examined the predictive and incremental predictive validity of past-month suicidal behavior and ideation for short-term suicidal behavior among adolescents at high risk of suicide. The study was conducted in 2014 on a sample of 85 adolescents (90.6% females) who participated at follow-up (85.9%) out of the 99 (49.7%) baseline respondents. All adolescents were recruited from a specialized suicide-prevention clinic in Denmark. Through multivariate logistic regression analyses, we examined whether baseline suicidal behavior predicted subsequent suicidal behavior (actual attempts and suicidal behavior of any type, including preparatory acts, aborted, interrupted and actual attempts; mean follow-up of 80.8 days, SD = 52.4). Furthermore, we examined whether suicidal ideation severity and intensity incrementally predicted suicidal behavior at follow-up over and above suicidal behavior at baseline. Actual suicide attempts at baseline strongly predicted suicide attempts at follow-up. Baseline suicidal ideation severity and intensity did not significantly predict future actual attempts over and above baseline attempts. The suicidal ideation intensity items deterrents and duration were significant predictors of subsequent actual attempts after adjustment for baseline suicide attempts and suicidal behavior of any type, respectively. Suicidal ideation severity and intensity, and the intensity items frequency, duration and deterrents, all significantly predicted any type of suicidal behavior at follow-up, also after adjusting for baseline suicidal behavior. The present study points to an incremental predictive validity of the C-SSRS suicidal ideation scales for short-term suicidal behavior of any type among high-risk adolescents.
