I just want to add one comment, that it is really important to evaluate any interventions around trauma. We do know that, for example, critical incident stress debriefing, which is a group-based intervention after someone is exposed to trauma, was created to prevent PTSD, but it turned out to actually not be helpful and potentially cause harm. The key thing we've learned in the trauma and PTSD literature is that everyone recovers from trauma differently, and that if someone doesn't want to go in a group and talk about the trauma, we don't force people to do that.
