There are evidence-based treatments such as Cognitive Behaviour Therapy, and Eye Movement Desensitization Reprocessing Treatment that have shown through multiple outcome studies to be effective. Many persons diagnosed with PTSD are often diagnosed with depression.
A well rounded and skills-based treatment is best advised for those seeking help with symptoms of depression and PTSD. While ‘talk therapy’ is traditional and familiar, the research shows that ‘talk therapy’ alone is not successful in treating moderate to severe depression.
Ultimately, a group that teaches both CBT skills and Containing Anxiety skills is most effective combined with EMDR therapy. Skills groups are lacking. Therefore, mental health treatment should include skills-based groups as part of clinical treatment.
