OBJECTIVE To describe the test construction procedure and evaluate the internal consistency, criterion-referenced validity, and diagnostic accuracy of the Child/Adolescent Self-Report Version of the UCLA PTSD Reaction Index for DSM-5 (RI-5) across 2 independent samples. METHOD Study 1 examined the clarity, developmental appropriateness, acceptability of individual RI-5 items, and internal consistency and criterion-referenced validity of the full test. The study 1 sample included 486 youth recruited from 2 major US cities who completed the RI-5 and a measure of depression. Study 2 evaluated the reliability and diagnostic accuracy of the RI-5 in 41 treatment-seeking youth who completed the RI-5 and a "gold standard" structured diagnostic interview, the Clinician-Administered PTSD Scale for DSM-5-Child/Adolescent Version. RESULTS RI-5 total scale scores showed excellent internal consistency in the 2 samples. Study 1 provided evidence of criterion-referenced validity, in that total scale scores correlated positively with depressive symptoms. Study 2 provided evidence of diagnostic accuracy (including discriminant-groups validity). RI-5 total scores discriminated youth with from youth without PTSD as benchmarked against the structured diagnostic interview. Further, receiver operating characteristic analyses using a total score of 35 provided excellent diagnostic classification accuracy (area under the curve 0.94). CONCLUSION The developmental appropriateness and diagnostic accuracy of the RI-5 support its utility for clinical assessment, case conceptualization, and treatment planning in different child-serving systems, including schools, juvenile justice, child welfare, and mental health.

验证DSM-5的UCLA PTSD反应指数：青少年的知情评估工具。

目的描述两个独立样本中DSM-5（RI-5）的UCLA PTSD反应指数的儿童/青少年自我报告版本的内部一致性，标准参考的有效性和诊断准确性，以描述测试的构建程序。方法研究1检验了RI-5单个项目的清晰度，发展适当性，可接受性以及完整测试的内部一致性和标准参考的有效性。研究1样本包括从美国2个主要城市招募的486名年轻人，他们完成了RI-5和抑郁程度。研究2评估了RI-5在41位完成RI-5治疗的寻求治疗的青年中的可靠性和诊断准确性，并进行了“金标准”结构化诊断访谈，这是由临床医生管理的DSM-5-儿童/青少年版PTSD量表。 。结果RI-5总分评分在2个样品中显示出极好的内部一致性。研究1提供了标准参照效度的证据，因为总分评分与抑郁症状呈正相关。研究2提供了诊断准确性（包括判别组有效性）的证据。RI-5总分将青少年与未患有PTSD的青少年区别开来，以结构化诊断性访谈为基准。此外，使用总分35的接收器工作特性分析提供了出色的诊断分类精度（曲线下面积0.94）。结论RI-5的发展适当性和诊断准确性支持其在不同的儿童服务系统（包括学校，少年司法，
