The Internet has proven to be an effective medium for delivering curative interventions for a range of psychological disorders, including posttraumatic stress disorder (PTSD). For the prevention of PTSD, e-health solutions have so far been scarce, even though the interactivity and accessibility of the Internet medium could be extremely beneficial in offering these types of interventions early after trauma. In this article, we present Trauma TIPS, our interactive e-health intervention for an injured trauma population. Trauma TIPS is aimed at the reduction of acute distress and acute arousal resulting from a traumatic injury, and the prevention of long-term symptoms of PTSD. In the six steps of the program, several cognitive behavioural techniques are presented including: psychoeducation, modeling, relaxation and in vivo exposure, and the use of various audiovisual features. The main emphasis is placed on the patient building resilience after traumatic injury and regaining control over his or her life. Since most single-session interventions that were offered to victims of psychological trauma have shown to be ineffective or are even associated with an increased risk for symptoms of PTSD, we considered that careful testing of this treatment’s efficacy is warranted. Currently, a randomised controlled trial is being carried out to test the efficacy of Trauma TIPS.
