UCLA Posttraumatic Stress Disorder Reaction Index for DSM-5 (PTSD-RI) – Child/Adolescent Version

TF-CBT Cohorts 16-18

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.

UCLA PTSD RI for DSM-5 Subscales: Descriptive Statistics

Repeated Measures:  Repeated measures analyses (paired samples t-tests) were conducted to examine pre-post group mean differences on UCLA PTSD-RI subscales and Total scores.  Analyses showed statistically significant improvement in PTSD symptoms and severity in all domains.

UCLA PTSD RI for DSM-5 Subscales: Pre-post Treatment Mean Scores

UCLA PTSD RI for DSM-5 Total Severity Scores: Pre-post Treatment Mean Scores

Individual Clinically-Significant Change: At pre-treatment, 348 clients had pre-treatment UCLA PTSD-RI Total Severity scores at or above the clinical cut-off score of 35. Of note, 143 clients were missing post-treatment data for the UCLA PTSD-RI Total Severity scores.  Analysis of the clients with post-treatment data showed that the UCLA PTSD-RI Total Severity scores for 155 of 205 (76%) of these clients decreased to non-clinically significant levels at post-treatment.
