The Suicide Risk Assessment and Management Decision Tree (DT) is a clinician-administered assessment that leads to risk categorizations that correspond with actionable strata. This study investigated the construct validity and test-retest reliability of the DT risk categories across two time points.
Outpatients (N = 731) completed a battery of self-report measures. Spearman's correlations were used to examine the relationships between DT suicide risk level and suicidal symptoms, theory-based risk factors, psychiatric correlates, and DT suicide risk level at Timepoint 2. Correlations were analyzed for significant differences to examine the divergent validity of the DT.
Results, overall, were in line with hypotheses, with the exception of depression and thwarted belongingness.
Findings provide evidence for the reliability, convergent validity, and discriminant validity of the DT. This clinician-administered suicide risk assessment may be useful for standardization of the assessment and management of suicide risk in outpatient clinical settings.
自杀风险评估和管理决策树（DT）是一种由临床医生管理的评估方法，可将风险分类与可操作的层次相对应。本研究在两个时间点上调查了 DT 风险类别的结构有效性和重测信度。
门诊患者（N=731）完成了一系列的自我报告测量。使用 Spearman 相关系数来检验 DT 自杀风险水平与自杀症状、基于理论的风险因素、精神科相关性以及时间点 2 时的 DT 自杀风险水平之间的关系。分析相关性是否存在显著差异，以检验 DT 的区别效度。
总体结果与假设一致，但抑郁和归属感受挫除外。
这些发现为 DT 的可靠性、聚合效度和区分效度提供了证据。这种由临床医生管理的自杀风险评估可能有助于在门诊临床环境中标准化评估和管理自杀风险。
