The aim of this study was to determine optimally efficient cutoff scores on the Posttraumatic Stress Disorder Checklist (PCL) for identifying full posttraumatic stress disorder (PTSD) and partial PTSD (P-PTSD) in active-duty Marines and Sailors. Participants were 1,016 Marines and Sailors who were administered the PCL and Clinician-Administered PTSD Scale (CAPS) 3 months after returning from Operations Iraqi and Enduring Freedom. PCL cutoffs were tested against three CAPS-based classifications: full PTSD, stringent P-PTSD, and lenient P-PTSD. A PCL score of 39 was found to be optimally efficient for identifying full PTSD. Scores of 38 and 33 were found to be optimally efficient for identifying stringent and lenient P-PTSD, respectively. Findings suggest that the PCL cutoff that is optimally efficient for detecting PTSD in active-duty Marines and Sailors is substantially lower than the score of 50 commonly used by researchers. In addition, findings provide scores useful for identifying P-PTSD in returning service members.
本研究的目的是确定创伤后应激障碍检查表（PCL）上的最佳有效临界分数，以识别现役海军陆战队队员和水兵中的完全创伤后应激障碍（PTSD）和部分创伤后应激障碍（P-PTSD）。研究对象为1016名海军陆战队队员和水兵，他们在从伊拉克行动和持久自由行动返回3个月后接受了PCL和临床医生管理的PTSD量表（CAPS）测试。根据基于CAPS的三种分类对PCL临界分数进行了测试：完全PTSD、严格P-PTSD和宽松P-PTSD。结果发现，PCL分数为39时对于识别完全PTSD具有最佳效率。分数为38和33时分别对于识别严格P-PTSD和宽松P-PTSD具有最佳效率。研究结果表明，在现役海军陆战队队员和水兵中检测PTSD的最佳有效PCL临界分数远低于研究人员常用的50分。此外，研究结果提供了有助于识别归国服役人员中P-PTSD的分数。
