Solution Focussed Therapy

Like CBT solution focused therapy is a short term and goal oriented therapy. 
This therapy is about discovering solutions and identifying what is already working, so you can do more of it, as well as identifying what doesn't work so you can do less of it! 

The emphasis is on the future, not the past.  In common with many therapies the client is believed to be the best expert about what it takes to change his or her life. Creating a detailed picture of what it will be like when life is better creates a feeling of hope, and this makes the solution seem possible.

Evidence for Solution-Focused Brief Therapy
In a review of 15 studies that have used Solution-focused brief therapy (SFBT) in 2000, the authors found there was preliminary support for its effectiveness, as positive outcomes were shown by the majority of participants.
