心理健康专家一直在争论创伤后应激障碍（PTSD）是否可以从创伤事件的正常反应中定性区分。这场争论已经被许多创伤暴露个体的证据部分呈现PTSD与重大损害和寻求帮助的行为有关的迹象所推动。作者研究了创伤后应激障碍的潜在结构在一个大样本的男性退伍军人。三个分类程序MAMBAC，MAXEIG和L模式进行了3个指标集从临床访谈和PTSD的自我报告措施。跨程序的结果，一致性检验，模拟比较数据的分析都收敛在一个维度的解决方案，表明创伤后应激障碍反映了压力反应连续体的上端，而不是一个离散的临床综合征。
Mental health professionals have debated whether posttraumatic stress disorder (PTSD) can be qualitatively distinguished from normal reactions to traumatic events. This debate has been fueled by indications that many trauma-exposed individuals evidence partial presentations of PTSD that are associated with significant impairment and help-seeking behavior. The authors examined the latent structure of PTSD in a large sample of male combat veterans. Three taxometric procedures-MAMBAC, MAXEIG, and L-Mode-were performed with 3 indicator sets drawn from a clinical interview and a self-report measure of PTSD. Results across procedures, consistency tests, and analysis of simulated comparison data all converged on a dimensional solution, suggesting that PTSD reflects the upper end of a stress-response continuum rather than a discrete clinical syndrome.
