大量证据表明，创伤后应激障碍（PTSD）症状的频率和强度与女性性别（例如，Kaplow等人，2005）和年龄（例如，Meiser-Stedman等人，2008年）。关于生物学性别和年龄与PTSD潜在因素结构之间的关系，人们知之甚少。该研究系统地检查了性别和年龄作为经验支持的五因素PTSD模型的全部因素结构参数的候选调节因子的作用（Elhai等人，2011年）。样本包括6591创伤暴露的儿童和青少年从国家儿童创伤压力网络的核心数据集。使用不变性检验（Gregorich，2006）和比较拟合指数差值（Cheung和Rensvold，2002）进行的验证性因素分析反映了各年龄组间供试品截距的混合模式。青少年子样本产生较低的残差方差，反映了更少的测量误差比儿童子样本。性别没有显示出强大的调节作用。最后，我们讨论了临床评估，理论建设和未来的研究的影响。(C)2013爱思唯尔爱尔兰有限公司版权所有。
A substantial body of evidence documents that the frequency and intensity of posttraumatic stress disorder (PTSD) symptoms are linked to such demographic variables as female sex (e.g., Kaplow et al., 2005) and age (e.g., Meiser-Stedman et al., 2008). Considerably less is known about relations between biological sex and age with PTSD's latent factor structure. This study systematically examined the roles that sex and age may play as candidate moderators of the full range of factor structure parameters of an empirically supported five-factor PTSD model (Elhai et al., 2011). The sample included 6591 trauma-exposed children and adolescents selected from the National Child Traumatic Stress Network's Core Data Set. Confirmatory factor analysis using invariance testing (Gregorich, 2006) and comparative fit index difference values (Cheung and Rensvold, 2002) reflected a mixed pattern of test item intercepts across age groups. The adolescent subsample produced lower residual error variances, reflecting less measurement error than the child subsample. Sex did not show a robust moderating effect. We conclude by discussing implications for clinical assessment, theory building, and future research. (C) 2013 Elsevier Ireland Ltd. All rights reserved.
