BACKGROUND Posttraumatic stress disorder (PTSD) is a major public health concern with long-term sequelae. There are no accepted interventions delivered in the immediate aftermath of trauma. This study tested an early intervention aimed at modifying the memory to prevent the development of PTSD before memory consolidation. METHODS Patients (n = 137) were(More)
OBJECTIVE Recent data have supported the use of an early exposure intervention to promote a reduction in acute stress and posttraumatic stress disorder (PTSD) symptoms after trauma exposure. The present study explored a comprehensive predictive model that included history of trauma exposure, dissociation at the time of the trauma and early intervention, and(More)
The high prevalence of trauma exposure and subsequent negative consequences for both survivors and society as a whole emphasize the need for secondary prevention of posttraumatic stress disorder. However, clinicians and relief workers remain limited in their ability to intervene effectively in the aftermath of trauma and alleviate traumatic stress reactions(More)
BACKGROUND Civilian posttraumatic stress disorder (PTSD) and combat PTSD are major public health concerns. Although a number of psychosocial risk factors have been identified related to PTSD risk, there are no accepted, robust biological predictors that identify who will develop PTSD or who will respond to early intervention following trauma. We wished to(More)
Background and aims Limited treatment options are available for trichotillomania (TTM) and most have modest outcomes. Suboptimal treatment results may be due to the failure of existing approaches to address all TTM styles. Methods Thirty-eight DSM-IV TTM participants were randomly assigned across two study sites to Dialectical Behavior Therapy (DBT)(More)
OBJECTIVE This study investigated the impact of avoidant coping on treatment outcome in rape-related posttraumatic stress disorder (PTSD). METHOD Adult women with rape-related PTSD (N = 62) received 9 sessions of prolonged exposure (PE) or eye movement desensitization and reprocessing (EMDR). The mean age for the sample was 34.7 years, and race or(More)
OBJECTIVES To assess gender differences in the proportion of adolescents reporting teen dating violence (TDV) and the frequency of TDV at multiple age points across adolescence in a high-risk sample of youth with previous exposure to violence. METHODS A cross-sectional, high-risk sample of boys and girls (n = 1149) ages 11 to 17 years completed surveys(More)
PURPOSE The goal of the present research was to identify distinct latent classes of adolescents that commit teen dating violence (TDV) and assess differences on demographic, behavioral, and attitudinal correlates. METHODS Boys and girls (N = 1,149; Mage = 14.3; Grades 6-12) with a history of violence exposure completed surveys assessing six indices of TDV(More)
Eleven cloned and uncloned measles virus-specific T cell lines were generated from peripheral blood lymphocytes obtained from a patient with multiple sclerosis and were assayed for measles polypeptide specificity. Three clones reacted specifically with the fusion (F) protein and one recognized the hemagglutinin (HA). Two reacted with whole virus but not(More)
OBJECTIVE This study analyzed predictors of post-traumatic stress disorder (PTSD) in civilian trauma victims to assess how peritraumatic dissociation (PD) relates to PTSD symptom development. We examined PD and PTSD symptoms from a prior trauma simultaneously to better understand the extent to which past and current reactions to a trauma can predict the(More)
