Longer term psychotherapy works according to a study published in JAMA

A study which appeared in the October 1, 2008 issue of the Journal of the American Medical Association which found that long term psychodynamic psychotherapy works. Here is a snippet from the article:

People with complex mental disorders or personality disorders would benefit from long-term psychodynamic psychotherapy that lasts at least a year or longer, according to new research.

Published in the Oct. 1 issue of the Journal of the American Medical Association, the German study found that compared to the more commonly used short-term therapy, long-term psychotherapy left people better off. In fact, the number of therapy sessions the patients had was directly correlated to improvements in symptoms.

"Long-term psychodynamic psychotherapy was significantly superior to shorter forms of psychotherapy applied in the control groups. This was true with regard to overall effectiveness, target problems, and personality functioning," said the study's lead author, Falk Leichsenring, a professor of psychotherapy research in the department of psychosomatic medicine and psychotherapy at the University of Giessen in Germany.

"With regard to overall effectiveness, on average, patients with complex mental disorders were better off after treatment with long-term psychodynamic psychotherapy than 96 percent of the patients in the comparison groups. Thus, this meta-analysis provides evidence that long-term psychodynamic psychotherapy is an effective treatment for complex mental disorders," said Leichsenring.

"This study provides a great value for doctors and for patients, and one would hope could have an influence on policy decisions," added Dr. Charles Goodstein, a clinical professor of psychiatry at the New York University School of Medicine and Langone Medical Center in New York City.
