移动技术为实时或接近实时地评估自杀意念和行为提供了新的可能性。目前尚不清楚如何使用密集的纵向数据来识别近端风险并为临床决策提供信息。本研究以青少年精神科住院病人(N=32,年龄13-17岁,75%为女性)为研究对象,通过使用日常日记,我们阐述了三步流程的应用,以识别自杀相关危机的早期迹象。使用受试者工作特征曲线(ROC)分析,我们考虑了12个特征的效用——在出院后的前两周(观察值=360),使用6个危险因素的每日评分的均值和方差来构建——以确定两周后的自杀危机。由单一危险因素导出的模型具有中等的预测精度(ROC曲线下面积[AUC] 0.46-0.80),而几乎所有由危险因素组合导出的模型都具有较高的准确性(AUC 0.80-0.91)。基于这一例证,我们讨论了临床决策和未来研究的意义。
Mobile technology offers new possibilities for assessing suicidal ideation and behavior in real- or near-real-time. It remains unclear how intensive longitudinal data can be used to identify proximal risk and inform clinical decision-making. In this study of adolescent psychiatric inpatients (N=32, ages 13–17, 75% female), we illustrate the application of a 3-step process to identify early signs of suicide-related crises using daily diaries. Using Receiver Operating Characteristic Curve (ROC) analyses, we considered the utility of 12 features—constructed using means and variances of daily ratings for six risk factors over the first two weeks post discharge (observations=360)—in identifying a suicidal crisis two weeks later. Models derived from single risk factors had modest predictive accuracy (Area Under the ROC Curve [AUC] 0.46–0.80) while nearly all models derived from combinations of risk factors produced higher accuracy (AUCs 0.80–0.91). Based on this illustration, we discuss implications for clinical decision-making and future research.
