Prevention of Combat-related PTSD Using Attention Bias Modification (ABM): A Randomized Controlled Trial

PTSD Clinical Trial

Official title: Prevention of Posttraumatic Symptoms in IDF Soldiers Using Attention Bias Modification (ABM): A Randomized Controlled Trial

Status Completed

Clinical Trial Summary

Military deployment to combat zones involves exposure to trauma at a higher than average rate and therefore presents a unique opportunity to study predisposing factors to posttraumatic stress reactions and test strategies designed to prevent and ameliorate posttraumatic symptoms. Decades of scientific research on the origins of resilience and vulnerability to combat-related posttraumatic stress symptoms revealed various predisposing and protective factors. All these factors however, offer limited opportunity for systematic pre-deployment prevention efforts. Considering the magnitude of psychological adjustment difficulties encountered by combat personnel in deployment and the limited access to existing evidence-based therapies for PTSD, the development and testing of a novel evidence-based and theory-driven prevention protocol for these problems is of considerable significance. The current study translates cognitive-neuroscience knowledge and attention bias modification research into a novel computerized training tool that could be easily delivered to soldiers during different stages of the deployment cycle. If proved efficacious in reducing risk for posttraumatic symptoms ABMT could be integrated into the Army's resilience training program. Thus, we propose a longitudinal double-blind randomized controlled study of ABMT in soldiers. We will assess attention bias and symptoms before deployment, will randomly assign soldiers to either 8 ABMT sessions, 4 ABMT sessions, 8 Placebo training sessions, or no training. Following 6 months of deployment to combat zone symptoms will be assessed again.
