Objective: Prior investigations suggest the relative equivalence of the DSM-IV and DSM-5 versions of the Posttraumatic Stress Disorders (PTSD) Checklist, yet no investigations have assessed the psychometric properties of the scales in pragmatic trials of acutely injured trauma survivors.

Method: DSM-IV and DSM-5 versions of the PTSD Checklist were included in follow-up interviews of physically injured patients enrolled longitudinally in a pragmatic clinical trial; pragmatic trials aim to efficiently implement research procedures to inform healthcare system policy changes. Psychometric comparisons of the DSM-IV, DSM-5, and a 20-item blended version of the scale included evaluations of internal consistency, correlational assessments, evaluation of item level agreements, and estimation of DSM-5 cutoffs that optimize electronic health record screening protocols.

Results: 128 patients were included in the pragmatic psychometric study. Cronbach’s alphas for the 3 versions of the PTSD Checklist ranged from 0.93 to 0.95. Correlations between the 3 scales ranged from 0.79 to 0.99. All 3 measures demonstrated excellent convergent and discriminant properties. Item level agreement ranged from 70-80%. For the DSM-5 and blended versions of the scale, a score of 30 and 24, respectively, best approximated the DSM-IV cutoff of ≥35 that had previously optimized PTSD detection in conjunction with EHR screening.

Conclusions: Among injured trauma survivors, the psychometric performance of the DSM-IV PTSD Checklist with the addition of the 4 new DSM-5 PTSD Checklist items is nearly equivalent to the DSM-5 PTSD Checklist. The investigation also suggests that pragmatic psychometric methods can catalyze the rapid translation of research findings into real-world practice settings.

目标：先前的调查表明，DSM-IV 和 DSM-5 版本的创伤后应激障碍 (PTSD) 清单相对等效，但没有调查评估过急性创伤幸存者的实用试验中量表的心理测量特性。

方法：将 DSM-IV 和 DSM-5 版本的 PTSD 检查表纳入一项实用临床试验纵向登记的身体受伤患者的后续访谈中；实用试验旨在有效地实施研究程序，以告知医疗保健系统政策的变化。DSM-IV、DSM-5 和 20 项混合版本的量表的心理测量比较包括内部一致性评估、相关性评估、项目水平协议评估以及优化电子健康记录筛查的 DSM-5 临界值的估计协议。

结果： 128 名患者被纳入实用心理测量研究。PTSD 检查表的 3 个版本的 Cronbach alpha 介于 0.93 到 0.95 之间。3 个量表之间的相关性介于 0.79 到 0.99 之间。所有 3 个度量都表现出出色的收敛性和判别性。项目级别的一致性范围为 70-80%。对于 DSM-5 和混合版本的量表，分数分别为 30 和 24，最接近 DSM-IV 临界值 ≥35，该临界值先前已结合 EHR 筛查优化了 PTSD 检测。

结论：在受伤的创伤幸存者中，添加 4 个新 DSM-5 PTSD 检查表项目的 DSM-IV PTSD 检查表的心理测量表现几乎等同于 DSM-5 PTSD 检查表。调查还表明，实用的心理测量方法可以促进将研究结果快速转化为现实世界的实践环境。
