• 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 (α = .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.
