Jonathan Shedler:  The Efficacy of Psychodynamic Psychotherapy
         [American Psychologist.  2010: Vol. 65, No. 2, 98–109]  

This study documents the growing scientific research showing the greater effectiveness of Psychodynamic Psychotherapy over Cognitive Behavior Therapy for many psychiatric conditions.  The improvement in the patients who received  Psychodynamic Psychotherapy actually increased over time, even after the treatment had actually terminated.

While medication in conjunction with psychotherapy can be useful for some patients, Shedler cites studies that show that Psychodynamic Psychotherapy is far more effective for depression in the long run compared to medication alone.
