CBT is widely used for OCD and other anxiety disorders. Experts in OCD, in fact, will tell you it is THE only treatment (if it includes exposure and response prevention) for OCD. In a literature review of 27 published articles that researched CBT for anxiety, the authors found that indeed, CBT demonstrated efficacy over placebos that lasted after termination of treatment.

CBT for PTSD. The Department of Veteran Affairs reports that CBT results in 60-80% reduction in PTSD symptoms in civilian populations (esp. survivors of rape). As for pyschodynamic approaches, the Department states: "Research on the use of psychodynamic therapy is difficult to conduct because psychodynamic techniques do not focus on symptom reduction. Instead, they focus on more fluid intra- and interpersonal processes. To date, there has been only one randomized clinical trial on the efficacy of psychodynamic treatment in reducing PTSD symptoms. In this trial, 18 sessions of Brief Psychodynamic Psychotherapy were shown to effectively reduce PTSD intrusion and avoidance symptoms by approximately 40%, and improvement was sustained for 3 months. While clinicians often support the utilization of psychodynamic techniques in the treatment of trauma, particularly in the treatment of more complex trauma, much more research is needed to demonstrate the techniques effectiveness with PTSD."

CBT for PTSD in patients who also have schizophrenia. According to a study published in the Journal of Anxiety Disorders, researchers found that 12 of 13 completers of an 11-week program in CBT to reduce PTSD had such a reduction in symptoms that 3 months later, 10 no longer met the criteria for PTSD.

There are many, many more sources of evidence out there. I will post about DBT later in the week.
