这项研究的目的是比较PC-PTSD和GHQ-12在初级保健患者中发现新的PTSD病例方面的差异。从11,230名VA初级保健患者的临床数据库中提取关于PC-PTSD、GHQ-12和精神诊断的数据。信号检测分析和似然比被用来比较屏幕。用Logistic回归分析来检验PC-PTSD在控制GHQ后对PTSD的预测作用。PC-PTSD的阳性预测值高于GHQ(41%对31%)。结合两种筛查的阳性结果，预测PTSD的似然比最高(LR=17.3)，而仅PC-PTSD的阳性结果(LR=8.3)或GHQ的阳性结果(LR=4.6)。PC-PTSD的表现略好于GHQ，并在识别PTSD方面提供了独特的信息，这表明在初级保健环境中使用障碍特定筛查是重要的。爱思唯尔有限公司出版。
The aim of this study was to compare the PC-PTSD and GHQ-12 in detecting new cases of PTSD among primary care patients. Data on the PC-PTSD, GHQ-12 and psychiatric diagnoses was extracted from clinical databases for 11,230 VA primary care patients. Signal detection analyses and likelihood ratios were used to compare screens. Logistic regression analysis was used to examine the prediction of PTSD by the PC-PTSD after controlling for the GHQ. The PC-PTSD had a higher positive predictive value than the GHQ (41 percent vs. 31 percent). Combining positive results on the two screens in predicting PTSD yielded the highest likelihood ratio (LR = 17.3) compared to a positive result on the PC-PTSD only (LR = 8.3) or the GHQ only (LR = 4.6). The PC-PTSD performed slightly better than the GHQ and provided unique information in identifying PTSD, suggesting that disorder specific screens are important to use in primary care settings.
