Summary: If you have been in therapy you want to believe it "worked". We all do. And hopefully it did have a positive effect on you. But how do you know? How do therapists know if what they're doing really has resulted in improvements in their clients? Yes, we have controlled studies for many treatments which give us confidence that these techniques really do help people, but we also have a lot of "therapeutic" techniques that have not been thoroughly tested. Nonetheless, lots of amazing claims are made for their effectiveness and no doubt the people who provide these therapies really do believe that they work.
