Is Therapy Effective?

Did anyone ever wonder what type of therapies really work and which ones don't? There have been countless studies to try to determine the effectiveness of therapy. For example, it was found that psychotherapy is not the best form of therapy. It is time consuming and costs a lot of money. It is also not seen as a permanent solution to a problem. Furthermore, research has found that many people reported to be content after therapy no matter what type of therapy they received or what situation they were in.
      Because of this, I wonder if it really matters what type of therapy one receives. It seems important to choose the right type of therapy in order to treat a specific problem or disorder, but will it really be effective? I believe that certain therapies, like behavior therapies when a person is conditioned to change their behaviors, will be good for people with certain issues, like addictions. This seems to truly work. However, it is certain therapeutic techniques, such as therapeutic touch and light exposure therapies that do not seem real. In the end, does it really matter if the therapies are proven to work by researchers, or is the affect that the therapy has on a person what really matters?
