This study investigates whether modifying the instructions of the Posttraumatic Stress Disorder Checklist (PCL) for military survey research changes posttraumatic stress disorder (PTSD) symptom reporting or prevalence. The sample consisted of 1691 soldiers who were randomly assigned to complete 1 of 3 versions of the PCL, which differed only in the wording of the instructions. Group differences in demographic variables, combat exposure, mean PTSD symptoms, and PTSD prevalence estimates were examined. Results showed that there were no statistically significant differences in the outcomes across the PCL versions. The findings indicate that researchers may make modifications to the PCL instructions to meet research needs without affecting PTSD symptom reporting or prevalence estimates.
本研究调查了在军事调查研究中修改创伤后应激障碍检查表（PCL）的指导语是否会改变创伤后应激障碍（PTSD）症状报告或患病率。样本包括1691名士兵，他们被随机分配完成PCL三个版本中的一个，这三个版本仅在指导语措辞上有所不同。研究人员检查了人口统计学变量、战斗暴露情况、PTSD症状均值以及PTSD患病率估计值的组间差异。结果显示，PCL各版本的结果在统计学上没有显著差异。研究结果表明，研究人员可以修改PCL的指导语以满足研究需求，而不会影响PTSD症状报告或患病率估计。
