Simply put, yes it does, but not always.

Psychodynamic therapy has got a scientific record of its effectiveness for certain conditions (e.g. depression). However, because of the way it is carried out it is really hard to judge just how well it does work. The experts tend to argue amongst themselves whether it works, but we think the best judge of the issue are the patients themselves. For a scientific record of our effectiveness, icap uses the CORE system (Clinical Outcomes in Routine Evaluation). "The collective findings from this standardisation allow the professions for the first time to compare and contrast profiles of local service provision to national benchmarks".
A lot of patients have reported that it has helped them enormously, however, equally a lot of patients, really disliked it. These people tended to drop out of therapy quite quickly.

Psychodynamic therapy is one of the few mainstream therapies that focuses on aspects of your personality, and although it is used to treat a wide variety of conditions, it seems to us particularly suited for problems to do with personalities, and past and present relationships.

Therefore, the advice that we offer to you is that if this type of therapy appeals to you, then find out a bit more, and give it a go. There are a lot of people that are glad they did. However, be prepared to be open and honest, and be prepared to find the going difficult, especially at first. Even, if it doesn't seem appealing now, you may find someway down the line, that you would like to give it a go.

Like in all therapies, there are no guarantees.
