Subthreshold posttraumatic stress disorder (SPTSD), a condition that meets the full symptomatic criteria of posttraumatic stress disorder (PTSD) without subjective functional impairment, has yet to be fully investigated. In this study, we aimed to determine the prevalence and characteristics of SPTSD.
The web-based survey including psychiatric diagnosis and experience of human error was conducted in actively working train drivers in South Korea.
Of the 4,634 subjects, 103 (2.23%) were categorized as full PTSD and 322 (6.96%) were categorized as having SPTSD. Individuals with full PTSD showed higher impulsivity and anxiety compared to those with SPTSD and those without PTSD, while those with SPTSD had more frequent clinically meaningful depression, posttraumatic stress, and alcohol and nicotine dependence and significant human error.
Despite not qualifying as a subjective functional disability, SPTSD still had significant psychiatric symptoms. More clinical attentions need to be given to the diagnosis and treatment of SPTSD.
阈下创伤后应激障碍（SPTSD）是一种符合创伤后应激障碍（PTSD）全部症状标准但无主观功能损害的病症，尚未得到充分研究。在本研究中，我们旨在确定SPTSD的患病率和特征。
对韩国在职火车司机进行了包括精神科诊断和人为失误经历的网络调查。
在4634名受试者中，103人（2.23%）被归类为完全PTSD，322人（6.96%）被归类为患有SPTSD。与患有SPTSD和未患PTSD的个体相比，完全PTSD个体表现出更高的冲动性和焦虑，而患有SPTSD的个体临床上有更频繁的有意义的抑郁、创伤后应激以及酒精和尼古丁依赖，且有显著的人为失误。
尽管未被认定为主观功能残疾，但SPTSD仍有显著的精神症状。需要对SPTSD的诊断和治疗给予更多临床关注。
