创伤受害者的创伤后应激障碍（PTSD）的因素分析研究提供了关于如何概念化PTSD到症状类别的相互矛盾的假设。本研究使用了来自雨果飓风的5，664名儿童和青少年受害者自我报告的PTSD维度的验证性因素分析，比较了10种PTSD维度模型。PTSD最好由2阶PTSD因子表示，该因子表现为3个症状群（侵入/主动回避，麻木/被动回避和唤醒）。该模型在3个年龄组（儿童晚期、青春期早期和青春期晚期）上进行了交叉验证，结果表明各组之间存在因子不变性。创伤后应激障碍的症状变化的相对中心的创伤后应激障碍的基本尺寸，不同的关系与焦虑和创伤暴露的程度。分类标准和经验支持的PTSD理论的影响进行了讨论。
Factor analytic studies of trauma victims' posttraumatic stress disorder(PTSD) have offered conflicting hypotheses about how to conceptualize PTSD into symptom categories. The present study used confirmatory factor analyses of self-reported PTSD symptomatology from 5,664 child and adolescent victims of Hurricane Hugo to compare 10 models of PTSD dimensionality. PTSD was best represented by a 2nd-order PTSD factor that manifests in 3 symptom clusters (Intrusion/Active Avoidance, Numbing/Passive Avoidance, and Arousal). This model was cross-validated on 3 age groups (late childhood, early adolescence, and late adolescence), and results indicated factorial invariance across groups. PTSD symptoms varied in relative centrality to the underlying dimensions of PTSD, which differed in their relations with anxiety and degree of traumatic exposure. Implications for classification criteria and an empirically supported theory of PTSD are discussed.
