Psychotherapy of personality disorders.

This article reviews recent research examining the effectiveness of treating personality disorders with psychotherapy. Despite the prevalence and seriousness of these conditions, and the extensive clinical writings about them, research on the treatment of personality disorders has been limited. Much of the research is hampered by a multitude of difficult issues. Research from the past 3 years is reviewed, with an eye toward what new contributions the studies have made to the psychotherapy literature. Implications of their findings are considered and recommendations for future research are made.
