Objective To describe the test construction procedure and evaluate the internal consistency, criterion-referenced validity, and diagnostic accuracy of the Child/Adolescent Self-Report Version of the UCLA PTSD Reaction Index for DSM-5 (RI-5) across 2 independent samples. Method Study 1 examined the clarity, developmental appropriateness, acceptability of individual RI-5 items, and internal consistency and criterion-referenced validity of the full test. The study 1 sample included 486 youth recruited from 2 major US cities who completed the RI-5 and a measure of depression. Study 2 evaluated the reliability and diagnostic accuracy of the RI-5 in 41 treatment-seeking youth who completed the RI-5 and a “gold standard” structured diagnostic interview, the Clinician-Administered PTSD Scale for DSM-5—Child/Adolescent Version. Results RI-5 total scale scores showed excellent internal consistency in the 2 samples. Study 1 provided evidence of criterion-referenced validity, in that total scale scores correlated positively with depressive symptoms. Study 2 provided evidence of diagnostic accuracy (including discriminant-groups validity). RI-5 total scores discriminated youth with from youth without PTSD as benchmarked against the structured diagnostic interview. Further, receiver operating characteristic analyses using a total score of 35 provided excellent diagnostic classification accuracy (area under the curve 0.94). Conclusion The developmental appropriateness and diagnostic accuracy of the RI-5 support its utility for clinical assessment, case conceptualization, and treatment planning in different child-serving systems, including schools, juvenile justice, child welfare, and mental health.

UCLA PTSD reaction index for DSM-5 (PTSD-RI-5): a psychometric study of adolescents sampled from communities in eleven countries

Objective Children and adolescents who experience potentially traumatic events are at risk for developing posttraumatic stress disorder (PTSD). Although psychometrically sound measures are now available to assess these youths, brief tools are currently needed for screening purposes. Two studies were conducted to develop and validate the UCLA PTSD Reaction Index for DSM-5–Brief Form (RI-5-BF). Method Study 1 used item response theory models to derive the RI-5-BF from the UCLA PTSD Reaction Index for DSM-5 and assess its internal consistency using a sample of 486 trauma-exposed youths (mean age = 13.32 years, SD = 2.90) recruited through a practice research network. Study 2 used receiver operating characteristic analyses and diagnostic efficiency statistics to assess the discriminant-groups validity and clinical utility of the RI-5-BF in identifying children at different levels of PTSD risk using a sample of 41 treatment-seeking youths (mean age = 12.44 years, SD = 2.99). Results In study 1, item response theory models identified the 11 most informative items across their respective subscales. The RI-5-BF exhibited excellent internal consistency in both studies (α > .93). In study 2, receiver operating characteristic analyses indicated that an RI-5-BF score of 21 maximized sensitivity and specificity. Moreover, diagnostic likelihood ratios across multiple levels of scores provided support for the measure’s clinical utility in identifying different levels of PTSD risk. Conclusion These findings provide support for both the psychometric properties of the RI-5-BF as a brief screening measure for PTSD in children and adolescents and its utility for identifying youths meriting further assessment and consideration for treatment.

Screening for psychotrauma related symptoms: Japanese translation and pilot testing of the Global Psychotrauma Screen.

Background
Trauma-focused cognitive behavioral therapy is used to treat children who have experienced traumatic events and suffer from trauma-related disorders. Its effectiveness has been demonstrated in several randomized controlled studies. However, most of these studies have been performed in the United States, with few studies conducted in Asian countries. Therefore, we aimed to evaluate the feasibility of trauma-focused cognitive behavioral therapy in children who have experienced traumatic events and who suffer from trauma-related disorders in Japan.
