Filter by:The purpose of this study is to examine the effects of glucocorticoid administration following traumatic memory reactivation on psychiatric symptoms in veterans with combat-related PTSD, in addition to examining the effects of glucocorticoid administration following traumatic memory reactivation on physiological responses to veteran's personal combat memories. The following hypotheses will be tested: 1. Subjects who receive an exogenous glucocorticoid after traumatic memory reactivation will demonstrate fewer PTSD and depression symptoms one week later, compared to those who receive a placebo after traumatic memory reactivation. 2. The glucocorticoid reduction effects will be cumulative; that is, reduction will persist, and further post-reactivation glucocorticoid administration will further reduce symptoms 3. Decreases in PTSD and depression symptoms will persist at 1, 3, and 6 months for subjects receiving an exogenous glucocorticoid compared to those subjects receiving placebo 4. Subjects who receive an exogenous glucocorticoid after traumatic memory reactivation will demonstrate decreased physiological responses one week later, compared to those who receive a placebo after traumatic memory reactivation. 5. As with the psychological measures, suppression of the physiological measures will demonstrate both persistence over time and accumulation with subsequent post-reactivation glucocorticoid administration.
This proposal examines trauma and growth responses in the childhood cancer experience. It addresses a number of gaps and unanswered questions in the literature, while integrating several distinct but related lines of research. The rationale for this proposal is outlined briefly as follows: 1. Traumatic stress models focused on pathology dominate pediatric psychosocial oncology research despite empiric evidence of low levels of post-traumatic stress in this population. 2. The assumption of 'cancer as a traumatic event' has biased research designs (including lack of control comparisons) to focus on deficits and pathological outcomes. 3. This deficit-oriented approach has stimulated the development of interventions to treat or prevent PTSD, which may be unnecessary or even harmful. 4. Theoretical and empiric evidence suggests that a more common response to traumatic stress is growth and positive change, but posttraumatic growth phenomenon have been understudied in pediatric populations. 5. Cognitive and personality factors are important determinants of PTSD and positive growth outcomes, and some constructs from positive psychology theory may be particularly relevant in children with cancer. 6. Empirically, parents of children with cancer appear to be at higher risk of PTSD/PTSS, although results are not unequivocal, and the same research biases have applied to parental outcomes. This proposal includes assessment of parental PTSS and PTG, both as an outcome and a predictor of child outcomes.
Sleep impairment is the most often reported of the 17 PTSD symptoms and is considered one of the most refractory to treatment. This study proposes the use of sleep-directed hypnotherapy to address sleep issues as a complementary element to empirically supported Cognitive Processing Therapy (CPT) in treating PTSD in sexual and physical assault survivors. Specifically the study aims to: 1) compare the results of sleep-directed hypnosis plus CPT with CPT only, 2) to assess the relationship between sleep and PTSD symptoms, 3) to examine relationships between sleep improvement, PTSD symptom improvement, and the therapeutic elements (hypnosis, exposure, cognitive therapy) to determine mechanisms of action in the intervention, 4) to assess the relationship between sleep and physical reactivity to trauma-related cues and to other stimuli.
The purpose of this study is to determine whether Dialectical Cognitive Traumatherapy is effective in the treatment of severe and chronic Posttraumatic Stress Disorder (PTSD) following childhood sexual abuse.
