The PTSD Checklist for DSM-5 (PCL-5) is a widely used self-rated measure of DSM-5 PTSD symptoms. The goal of this systematic review was to synthesize research on the psychometric properties of the PCL-5 to guide clinical and research applications. We focused on reliability, validity, factor structure, optimal cutoff scores, and sensitivity to clinical change indices. A systematic review of the literature following PRISMA guidelines was conducted using PubMed, PsycINFO, CINAHL, and PTSDpubs with search terms capturing selected psychometric indices of the PCL-5. The inclusion criteria were: peer-reviewed publication in English; primary focus on the PCL-5 psychometrics; empirical study; and study with adult samples. The search yielded 265 studies; 56 papers (amounting to 64 studies) met inclusion criteria and were reviewed. Findings generally indicated evidence for: acceptable internal consistency and test-retest reliability; construct validity; a 7-factor Hybrid Model; recommended cutoff scores between 31-33; and ability to index sensitivity to clinical change. To further advance knowledge and applications of the PCL-5, we need more research on abbreviated versions of the PCL-5, bifactor modeling as applied to the PCL-5, as well as on PCL-5 item difficulty estimates, discrimination parameters, and clinical change score estimates.

DSM-5 的创伤后应激障碍 (PTSD) 检查表：现有心理测量证据的系统回顾。

DSM-5 的 PTSD 检查表 (PCL-5) 是一种广泛使用的 DSM-5 PTSD 症状自评量度。本系统综述的目的是综合 PCL-5 心理测量特性的研究，以指导临床和研究应用。我们关注可靠性、有效性、因子结构、最佳截止分数以及对临床变化指标的敏感性。使用 PubMed、PsycINFO、CINAHL 和 PTSDpubs 以及捕获 PCL-5 选定心理测量指数的搜索词，对遵循 PRISMA 指南的文献进行了系统回顾。纳入标准是：经过同行评审的英文出版物；主要关注 PCL-5 心理测量学；实证研究; 并用成人样本进行研究。检索产生了 265 项研究；56 篇论文（总计 64 项研究）符合纳入标准并经过审查。研究结果通常表明以下证据：可接受的内部一致性和重测可靠性；构建效度；7 因素混合模型；建议分数线在 31-33 之间；以及对临床变化敏感度的能力。为了进一步推进 PCL-5 的知识和应用，我们需要对 PCL-5 的缩写版本、应用于 PCL-5 的双因子建模以及 PCL-5 项目难度估计、判别参数和临床变化评分估计。
