There is a particular need for valid scales to screen for posttraumatic stress disorder (PTSD) among women who seek safe shelter from intimate partner violence. Screening to identify women who are at risk for PTSD can lead to early intervention that reduces the risk for PTSD-related outcomes such as poor decision making, inconsistent parenting, and behavior dysfunction among their children. The gold standard for diagnosing PTSD is the Clinician-Administered PTSD Scale for (5th ed.; ) (CAPS-5). A seven-item PTSD screen has been used for in this population and has a well-established cutoff score but has not been validated against the diagnostic criteria for PTSD. The study purpose was to establish concurrent validity for a seven-item screen for PTSD with the CAPS-5. Participants were 75 women, 18 years or older, who were residents of a 120-bed shelter in the southern United States. They spoke English or Spanish. They reported intimate partner physical or sexual violence within 4 months of their entry into the study. Following informed consent, data were collected in individual interviews, conducted in either English or Spanish. In addition to demographic data, the seven-item PTSD screen and the CAPS-5 were administered. A receiver operating characteristic (ROC) curve analysis was conducted to assess the concurrent validity of the seven-item PTSD screen with the CAPS-5. The seven-item PTSD screen results were significantly correlated with the CAPS-5 results in this sample (area under the curve [AUC] = .640, = 2.670, = .008). Sensitivity was 96.2, and observed specificity was 31.8. The seven-item PTSD screen demonstrates excellent sensitivity (e.g., 96% of true PTSD cases) and acceptable specificity (32% of non-PTSD cases) and can be used to quickly and accurately identify individuals for diagnostic assessment and intervention.
对于那些从亲密伴侣暴力中寻求安全庇护所的女性，特别需要有效的量表来筛查创伤后应激障碍（PTSD）。进行筛查以识别有患PTSD风险的女性，可促成早期干预，从而降低与PTSD相关后果的风险，如决策能力差、育儿方式不一致以及其子女的行为功能障碍。诊断PTSD的金标准是《临床医生管理的创伤后应激障碍量表（第5版）》（CAPS - 5）。一个七项PTSD筛查量表已用于该人群，且有既定的截断分数，但尚未根据PTSD的诊断标准进行验证。该研究的目的是确定一个七项PTSD筛查量表与CAPS - 5的同时效度。参与者为75名18岁及以上的女性，她们是美国南部一家拥有120张床位庇护所的居民。她们说英语或西班牙语。她们报告在进入研究的4个月内遭受过亲密伴侣的身体暴力或性暴力。在获得知情同意后，通过英语或西班牙语进行的个人访谈收集数据。除了人口统计学数据外，还实施了七项PTSD筛查量表和CAPS - 5。进行了受试者工作特征（ROC）曲线分析，以评估七项PTSD筛查量表与CAPS - 5的同时效度。在这个样本中，七项PTSD筛查量表的结果与CAPS - 5的结果显著相关（曲线下面积[AUC] = 0.640，z = 2.670，p = 0.008）。敏感性为96.2，观察到的特异性为31.8。七项PTSD筛查量表显示出极佳的敏感性（例如，96%的真正PTSD病例）和可接受的特异性（32%的非PTSD病例），可用于快速准确地识别个体以进行诊断评估和干预。
