The Global Psychotrauma Screen (GPS) is a brief transdiagnostic screener that covers a broad range of trauma-related disorders as well as risk factors known to influence the course of symptoms.
We analyzed data from African war refugees in Australia ( = 70), including the GPS, the Structured Clinical Interview for DSM-5 Disorders (SCID-5), the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), and the Brief Resilience Scale (BRS).
Using the Youden's Index to examine the clinical validity of the GPS subscales measuring PTSD, dissociation, depression, and generalized anxiety disorder (GAD), we found that a PTSD subscale score of 3 or higher, and a depression and dissociation subscale score of 1 or higher, was optimally efficient for detecting a probable diagnosis (Youden's = 0.76, = 0.72, and = 0.90, respectively) with high sensitivity and specificity. We were unable to test the GPS clinical validity for GAD due to the low GAD occurrence. The GPS resilience item was not related to the total score ( = 0.02), indicating low convergent validity for resilience. Risk factors, including current stressors and childhood trauma history, were related to more severe GPS symptom scores, while lack of resilience, social support, and history of mental illness were not.
We conclude that the GPS may be a useful screening tool for PTSD, depression, and the dissociative subtype in refugees.
全球心理创伤筛查量表（GPS）是一种简短的跨诊断筛查工具，涵盖了广泛的创伤相关障碍以及已知会影响症状发展过程的风险因素。
我们分析了澳大利亚的非洲战争难民（n = 70）的数据，包括GPS、《精神疾病诊断与统计手册》第5版障碍的结构化临床访谈（SCID - 5）、《精神疾病诊断与统计手册》第5版临床医生管理的创伤后应激障碍量表（CAPS - 5）和简易复原力量表（BRS）。
使用尤登指数来检验测量创伤后应激障碍、分离症状、抑郁和广泛性焦虑障碍（GAD）的GPS分量表的临床有效性，我们发现创伤后应激障碍分量表得分3或更高，以及抑郁和分离分量表得分1或更高，对于检测可能的诊断具有最佳效率（尤登指数分别为0.76、0.72和0.90），具有高敏感性和特异性。由于广泛性焦虑障碍发生率低，我们无法检验GPS对其的临床有效性。GPS复原力项目与总分无关（r = 0.02），表明复原力的聚合效度较低。风险因素，包括当前应激源和童年创伤史，与更严重的GPS症状得分相关，而缺乏复原力、社会支持和精神病史则不然。
我们得出结论，GPS可能是难民中创伤后应激障碍、抑郁和分离亚型的有用筛查工具。
