Examining the Effectiveness of an Early Psychological Intervention to Prevent Post-Traumatic Stress Disorder

2014-08-27 03:22:22 | BioPortfolio

Summary

This study will examine the use of prolonged exposure therapy on people who have recently experienced a trauma to prevent them from developing post-traumatic stress disorder.

Description

Post-traumatic stress disorder (PTSD) is a disorder that forms in response to a traumatic event. The symptoms of PTSD, such as hyper-arousal and re-experiencing the traumatic event, are common in all people who have recently experienced a trauma, but those who develop PTSD continue to have these symptoms more than a month after the trauma. Some researchers believe that developing PTSD is the result of a failure to adequately recover from the trauma. This study will determine whether providing a common form of treatment for PTSD, prolonged exposure (PE) therapy, to people who have recently experienced trauma will prevent them from developing PTSD. The study will also seek to identify predictive markers, such as hormone levels and genes, for developing PTSD.

Participation in this study will last 3 months. Participants will first undergo an evaluation session that will include an interview, questionnaires, and a medical chart review for blood pressure and heart rate measurements taken after their trauma. They will then be randomly assigned to receive either PE therapy or assessments only. Participants receiving PE therapy will complete three weekly treatment sessions, with the first occurring immediately after the evaluation session. Treatment will involve reviewing memories of a recent trauma out loud with a therapist and audio-recording these discussions for review at home. All participants will undergo assessments 1 and 3 months after the initial evaluation session. The 1-month assessment will involve an interview and questionnaires similar to the evaluation session, and the 3-month session will involve only a brief phone interview. Some participants will also be asked to complete an optional part of the study in which they provide two saliva samples to researchers: one to measure stress hormones and one to test for genetic bases of trauma response.

Medical and Biotech [MESH] Definitions

A class of traumatic stress disorders that is characterized by the significant dissociative states seen immediately after overwhelming trauma. By definition it cannot last longer than 1 month, if it persists, a diagnosis of post-traumatic stress disorder (STRESS DISORDERS, POST-TRAUMATIC) is more appropriate.

A class of traumatic stress disorders with symptoms that last more than one month. There are various forms of post-traumatic stress disorder, depending on the time of onset and the duration of these stress symptoms. In the acute form, the duration of the symptoms is between 1 to 3 months. In the chronic form, symptoms last more than 3 months. With delayed onset, symptoms develop more than 6 months after the traumatic event.

Anxiety disorders manifested by the development of characteristic symptoms following a psychologically traumatic event that is outside the normal range of usual human experience. Symptoms include re-experiencing the traumatic event, increased arousal, and numbing of responsiveness to or reduced involvement with the external world. Traumatic stress disorders can be further classified by the time of onset and the duration of these symptoms.

Syndromes which feature DYSKINESIAS as a cardinal manifestation of the disease process. Included in this category are degenerative, hereditary, post-infectious, medication-induced, post-inflammatory, and post-traumatic conditions.

A nonspecific term used to describe transient alterations or loss of consciousness following closed head injuries. The duration of UNCONSCIOUSNESS generally lasts a few seconds, but may persist for several hours. Concussions may be classified as mild, intermediate, and severe. Prolonged periods of unconsciousness (often defined as greater than 6 hours in duration) may be referred to as post-traumatic coma (COMA, POST-HEAD INJURY). (From Rowland, Merritt's Textbook of Neurology, 9th ed, p418)
