The UCLA PTSD Reaction Index for DSM 5 (UCLA PTSD RI – DSM 5) – Child/Adolescent Version* is a youth self-report measure of their PTSD symptoms (i.e., DSM 5 symptom categories B – E for PTSD diagnosis: re-experiencing, avoidance and numbing, increased arousal, and alterations in arousal and reactivity), dissociative symptoms, and their severity. 

Descriptive Statistics:  Pre- and post-treatment assessment measure means, standard deviations, and standard errors for each subscale of the UCLA PTSD-RI are listed in the table below, as well as the range of possible scores for each subscale.  The UCLA PTSD-RI for DSM 5 is in the process of being validated.  As such, clinical cutoffs are not yet available for analysis of this data.
