Sexual trauma survivors are reluctant to disclose such a history due to stigma. This is likely the case when estimating the prevalence of sexual trauma experienced in the military. The Veterans Health Administration has a program by which all former US military service members (Veterans) are screened for military sexual trauma (MST) using a questionnaire. Administrative data on MST screens and a change of status from an initial negative answer to positive and natural language processing (NLP) on electronic medical notes to extract concepts related to MST were used to refine initial estimates of MST among a random sample of 20,000 Veterans. The initial MST positive screen of 15.4% among women was revised upward to 21.8% using administrative data and further to 24.5% by adding NLP results. The overall estimate of MST status in women and men in this sample was revised from 8.1% to 13.1% using both data elements.
由于耻辱感，性创伤幸存者不愿透露这样的经历。在估计军队中性创伤的发生率时，情况可能就是如此。退伍军人健康管理局有一个项目，通过问卷调查对所有美国前军人（退伍军人）进行军事性创伤（MST）筛查。利用MST筛查的行政数据以及从最初的否定回答变为肯定回答的状态变化，以及电子病历上的自然语言处理（NLP）来提取与MST相关的概念，对20000名退伍军人的随机样本中的MST初始估计进行细化。女性最初的MST阳性筛查率为15.4%，使用行政数据后上调至21.8%，加上NLP结果后进一步上调至24.5%。使用这两个数据元素，该样本中女性和男性MST状态的总体估计从8.1%修订为13.1%。
