本文介绍了心理测量学特征的UCLA创伤后应激障碍反应指数DSM IV（PTSD-RI）来自大样本的儿童和青少年（N = 6,291）在国家儿童创伤压力网络中心进行评估。女孩的PTSD-RI总分总体平均值显著高于男孩。在7-9岁和16-18岁的患者中，PTSD-RI总评分的总体平均值和性别组内的PTSD-RI总评分均较高。不同种族/民族组的平均PTSD-RI总分无显著差异。PTSD-RI总量表在不同年龄范围、性别和种族/民族组中显示出良好至极好的内部一致性可靠性（α = 0.88 - 0.91）。PTSD-RI评分与TSCC-A上PTS子量表评分的相关性为整个样本以及性别、年龄和种族/种族组提供了收敛效度的证据，尽管没有判别效度。在对比以前报道的4因素模型，探索性因素分析显示，3个因素，主要反映了潜在的层面的创伤后应激障碍的DSM IV。PTSD-RI评分与功能/行为问题的比值比增加相关（比值比[OR] = 1-1.80）。鉴于受试者的创伤暴露、年龄和种族/民族范围广泛，这些发现令人震惊。
This article presents psychometric characteristics of the UCLA PTSD Reaction Index for DSM IV (PTSD-RI) derived from a large sample of children and adolescents (N = 6,291) evaluated at National Child Traumatic Stress Network centers. Overall mean total PTSD-RI score for girls was significantly higher as compared with boys. Age-related differences were found in that overall mean total PTSD-RI scores and within sex groups were higher among those aged 7-9 years and 16-18 years. There were no significant differences in mean total PTSD-RI scores across racial/ethnic groups. The PTSD-RI total scale displayed good to excellent internal consistency reliability across age ranges, sex, and racial/ethnic groups (alpha = .88-.91). Correlations of PTSD-RI scores with PTS subscale scores on the TSCC-A for the entire sample and within sex, age, and ethnic/racial groups provided evidence of convergent validity, although not discriminant validity. In contradistinction to previously reported 4-factor models, an exploratory factor analysis revealed 3 factors that mostly reflected the underlying dimensions of PTSD in DSM IV. PTSD-RI scores were associated with increased odds ratios for functional/behavior problems (odds ratio [OR] = 1-1.80). These findings are striking in light of the wide range of trauma exposures, age, and race/ethnicity among subjects.
