Veteran subjects with chronic, combat-related posttraumatic stress disorder (PTSD) are frequently used as research subjects in the study of PTSD. However, questions have consistently been raised regarding PTSD symptom exaggeration in veteran populations due to the relationship between PTSD symptoms and disability payments within the Veterans Affairs (VA) system. We used a variety of standardized forensic instruments frequently utilized in measuring symptom exaggeration - including the MMPI-2, the Structured Interview for Reported Symptoms (SIRS), the Structured Inventory of Malingered Symptomatology (SIMS), and the Miller Forensic Assessment Test (MFAST) - to examine symptom report in a group of veterans presenting for treatment at a VA residential PTSD treatment program. The majority of Vietnam veteran subjects in our study (53%) exhibited clear symptom exaggeration by SIRS criteria. Within the entire subject group, total SIRS scores correlated significantly with reported PTSD symptom severity as measured by the Clinician Administered PTSD Scale (CAPS).
患有与战斗相关的慢性创伤后应激障碍（PTSD）的退伍军人经常被用作PTSD研究的对象。然而，由于PTSD症状与退伍军人事务部（VA）系统内的残疾抚恤金之间的关系，关于退伍军人中PTSD症状夸大的问题一直存在。我们使用了多种常用于测量症状夸大的标准化法医工具——包括明尼苏达多相人格测验第二版（MMPI-2）、报告症状结构化访谈（SIRS）、伪装症状结构化量表（SIMS）和米勒法医评估测试（MFAST）——来检查一组在VA住院PTSD治疗项目中接受治疗的退伍军人的症状报告。我们研究中的大多数越南退伍军人受试者（53%）根据SIRS标准表现出明显的症状夸大。在整个受试者组中，SIRS总分与临床医生管理的PTSD量表（CAPS）测量的报告PTSD症状严重程度显著相关。
