In my opinion, while CBT has its place, it probably won't deal with issues at a deep enough level to really heal the effects of trauma. CBT is really good for depression and anxiety though, which both usually do go along with trauma.

Some therapies that are specifically indicated for trauma include EMDR, and somatic therapies. There will also be relationship issues that need to be addressed, especially with long-term trauma. Psychodynamic therapy is good for addressing relationship issues. Psychodrama is a good option. If you google "trauma work" you will find lots of inforation. Here's one site that I found - trauma specialists - http://www.traumapsychotherapy.com/ There are many therapists out there who specialize in trauma work.
