Abstract

The purpose of this study was to determine the reliability and validity of the UCLA PTSD Reaction Index for DSM-5 (PTSD-RI-5) among Japanese youth. This is the first study to explore psychometrics of the DSM-5 version of the PTSD-RI-5, as well as the first multisite study of an Asian population. This article presents psychometric characteristics of the PTSD-RI-5 derived from a sample of Japanese children and adolescents (N = 318). The PTSD-RI-5 total scale displayed good internal consistency reliability (α = 0.85). Correlations of PTSD-RI scores with the posttraumatic stress scores on the TSCC-A for the entire sample provided evidence of convergent validity. The four-factor structure of the PTSD-RI-5 was supported through confirmatory factor analysis in this sample. In conclusion, a DSM-5 version of the PTSD-RI-5 can be regarded as an adequate instrument for clinical and research purposes in Japan.
