PSYCHOTHERAPY IS HIGHLY EFFECTIVE: Overall psychotherapeutic methods (psychoanalysis, psychoanalytic psychotherapy) have a response rate of approximately 80 percent (i.e. roughly 8 out of 10 people report improvements after psychotherapy) and all psychotherapeutic methods produce similar beneficial effects [1-3]. The most important influence on treatment efficacy, aside from the personalities of the client and the therapist, is the relationship (therapeutic alliance) between the client and therapist [1, 2].
PSYCHOANALYSIS PRODUCES GREATER AND LONGER LASTING BENEFITS THAN OTHER METHODS. Studies have shown that 3 to 10 years after therapy clients who underwent psychoanalysis showed better personal and social functioning than those treated with other long-term psychotherapeutic methods [4-6].
QUALITY OF LIFE CONTINUES TO IMPROVE ONCE PSYCHOANALYSIS HAS ENDED. Apart from the fact that psychoanalytic psychotherapy is similarly effective when compared with other psychotherapeutic methods [1, 7], many clients choose psychoanalytic psychotherapy because it enhances quality of life in the long run [4, 8, 9]. Studies have shown the positive effects of psychoanalytic psychotherapy are enduring and that clients continue to improve after treatment has finished .
THE VARIOUS PSYCHOTEHRAPEUTIC METHODS ARE SIMILARLY EFFECTIVE. Although some studies have suggested that psychoanalytic psychotherapy is the best treatment for depression  whereas cognitive behavioral psychotherapy is the best treatment for bulimia , most studies indicate that all psychotherapeutic methods have similar effectiveness [1, 2, 13].
