Research on decreasing safety behaviors in therapy has been restricted to treatments for
other anxiety disorders and has not included PTSD. In order to address this gap and to
develop a widely accessible, cost-effective prevention, an internet-based, three-arm
randomized secondary PTSD prevention trial is proposed. Self-help psychoeducation on common
reactions to trauma and eliminating safety behaviors will be employed for participants who
have recently experienced a traumatic event. Participants will be randomized to receive (a)
psychoeducation on trauma symptoms only, (b) combined psychoeducation on trauma symptoms and
eliminating safety behaviors, or (c) monitoring only control. All participants will monitor
safety behaviors and trauma symptoms weekly for eight weeks. Psychoeducation materials will
be handouts and videos administered online via REDCap.
It is hypothesized that participants in both psychoeducation conditions will have a lower
incidence of PTSD, threat appraisal, and safety behaviors than participants in the
monitoring-only control. It is also hypothesized that participants who receive combined
psychoeducation on trauma symptoms and fading safety behaviors will have a lower incidence of
PTSD, threat appraisal, and safety behaviors at Weeks 4 and 8 than will participants who
receive psychoeducation on trauma symptoms only or participants in the monitoring-only
control. It is further hypothesized that the effects of combined psychoeducation on
preventing PTSD and threat appraisal will be mediated by decreased use of safety behaviors.
Finally, it is hypothesized that combined psychoeducation on trauma symptoms and fading
safety behaviors will be more effective in preventing PTSD for participants with higher
levels of safety behaviors or threat appraisal at baseline. If effective, this secondary
prevention program could be distributed widely to people who have recently experienced a
trauma to prevent their development of PTSD.
