This article presents psychometric characteristics of the UCLA PTSD Reaction Index for DSM IV (PTSD-RI) derived from a large sample of children and adolescents (N = 6,291) evaluated at National Child Traumatic Stress Network centers. Overall mean total PTSD-RI score for girls was significantly higher as compared with boys. Age-related differences were found(More)
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 To examine how parental responses following pediatric injury may influence their child's posttraumatic stress symptoms (PTSS). METHODS Heart rate (HR) from 82 pediatric injury patients was measured during emergency medical services (EMSs) transport and following hospital admission. Twelve-hour urinary cortisol levels were assessed upon(More)
The study objectives were to (a) examine the association between total number of trauma types experienced and child/adolescent behavioral problems and (b) determine whether the number of trauma types experienced predicted youth behavioral problems above and beyond demographic characteristics, using a diverse set of 20 types of trauma. Data came from the(More)
This study examined the relationship between acute cortisol responses to trauma and subsequent PTSD symptoms (PTSS) in children and their biological mothers. Urinary cortisol levels were assessed in 54 children aged 8-18 upon admission to a level-1 trauma center. Six weeks posttrauma, 15-hour urine samples were collected from children and their mothers.(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)
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)
UNLABELLED OBJECTIVE/INTRODUCTION: Secondary pharmacological interventions have shown promise at reducing the development of posttraumatic stress disorder symptoms (PTSS) in preclinical studies. The present study examined the preliminary efficacy of a 10-day low-dose (20 mg bid) course of hydrocortisone at preventing PTSS in traumatic injury victims. (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. The authors propose developmental refinements to the conceptual framework for PTSD(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)
