Shedler’s (2010) article ‘The Efficacy of Psychodynamic Psychotherapy’ dropped like a bombshell on the psychotherapy research world. He conducted a meta-analysis of the various meta-analyses on the efficacy of psychodynamic (psychoanalytic) psychotherapy. Shedler’s review yielded impressive results. Not only was psychodynamic psychotherapy proven to have large effect sizes (larger than cognitive-behavioral therapy, currently the most popular form of psychotherapy in the States), but patients were shown to continue to make gains even after the termination of treatment.
