We examined the underlying factor structure of the UCLA PTSD Reaction Index (PTSD-RI) using data from 6,591 children/adolescents exposed to trauma, presenting for treatment at any of 54 National Child Traumatic Stress Network (NCTSN) centers. Using confirmatory factor analysis, we tested the 3-factor DSM-IV PTSD model, 2 separate 4-factor models (Dysphoria(More)
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) should ensure systematic attention to age-specific manifestations and selective modifications of the diagnostic criteria for posttraumatic stress disorder (PTSD) among children and adolescents.

OBJECTIVE To longitudinally examine the impact of maternal posttraumatic stress disorder symptoms (PTSS) on child adjustment following a child's traumatic injury, focusing on child gender differences. METHODS Forty-one child traumatic injury victims aged 8-18 years and their biological mothers were interviewed over two follow-ups (6 weeks and 7 months).(More)
OBJECTIVE The present study prospectively examined the development of child PTSD symptoms (PTSS) and the impact of caregiver PTSS on child PTSS following injury. METHODS One hundred and eighteen ED patients and their caregivers were interviewed in-hospital and 2- and 6-weeks posttrauma. Structural equation modeling and hierarchical linear regressions(More)
Peritraumatic dissociation consistently predicts posttraumatic stress disorder (PTSD). Avoidant coping may serve as a mechanism through which peritraumatic dissociation contributes to PTSD symptoms. Path analysis was used to examine whether avoidant coping assessed 6 weeks following a motor vehicle accident mediated the relationship between in-hospital(More)
A substantial body of evidence documents that the frequency and intensity of posttraumatic stress disorder (PTSD) symptoms are linked to such demographic variables as female sex (e.g., Kaplow et al., 2005) and age (e.g., Meiser-Stedman et al., 2008). Considerably less is known about relations between biological sex and age with PTSD's latent factor(More)
