Post-traumatic stress disorder (PTSD) is a complex and chronic disorder that causes substantial distress and interferes with social and educational functioning. Consequently, identifying the risk factors that make a child more likely to experience traumatic distress is of academic, clinical and social importance. This meta-analysis estimated the population(More)
OBJECTIVE Increasingly, children are being diagnosed with psychiatric disorders, including preschool-age children. These diagnoses in young children raise questions pertaining to 1) how diagnostic algorithms for individual disorders should be modified for young age groups, 2) how psychopathology is best detected at an early stage, and 3) how to make use of(More)
BACKGROUND Negative trauma-related cognitions have been found to be a significant factor in the maintenance of post-traumatic stress disorder (PTSD) in adults. Initial studies of such appraisals in trauma-exposed children and adolescents suggest that this is an important line of research in youth, yet empirically validated measures for use with younger(More)
Posttraumatic stress disorder in children and adolescents has been studied only for the past 15-20 years and is the subject of a burgeoning corpus of research. Much research has focused on examining whether children and adolescents have the same responses to trauma as those experienced by adults. Many of the research tools used to investigate children's(More)
OBJECTIVE The authors investigated acute stress disorder and later posttraumatic stress disorder (PTSD) in children and adolescents who had been involved in assaults or motor vehicle accidents. METHOD They interviewed 93 patients 10-16 years old who were seen in an emergency department for having been assaulted or involved in a motor vehicle accident(More)
OBJECTIVE To describe the prevalence of acute stress disorder (ASD) symptoms and to examine proposed DSM-5 symptom criteria in relation to concurrent functional impairment in children and adolescents. METHOD From an international archive, datasets were identified that included assessment of acute traumatic stress reactions and concurrent impairment in(More)
The Children's Post-Traumatic Cognitions Inventory (CPTCI) is a self-report questionnaire that measures maladaptive cognitions in children and young people following exposure to trauma. In this study, the psychometric properties of the CPTCI were examined in further detail with the objective of furthering its utility as a clinical tool. Specifically, we(More)
Acute stress disorder (ASD) is a good predictor of posttraumatic stress disorder in adult populations, although the emphasis on dissociation symptoms within the diagnosis has been questioned. Recent studies suggest that ASD may also have application to children and adolescents. The present study examined properties of ASD within youth. A large (N = 367)(More)
BACKGROUND & OBJECTIVES The present study addresses gaps in knowledge regarding the association between trauma memory processes and posttraumatic stress responses in youth. Our primary goal was to explore the relative contribution of perceptions of trauma memory quality versus narrative trauma memory characteristics to explain overall adjustment. METHODS(More)
