I've been through two DBT programs. It is a very intense treatment, if done properly. For example, there is "homework" to be done, and you will need to be cooperative. Make sure you are willing to be prepared to work hard at it before you take it on.

DBT is very popular now, and it has been found to be helpful for problems such as BPD and BD. "Mindfulness" is one technique that's used in it--where a person is trained to concentrate on the present.
