I'm not referring to databases of clients, questionnaires about your symptoms or providing feedback to your therapist. When I use the term "evidence-based", I'm referring to the use of scientific studies hoping to prove that a specific treatment will help with a particular issue. Both proof and evidence-based have been mentioned several times in this thread. Maybe we're not thinking of the same thing. No one told me that it's highly overrated. That's an opinion I came to on my own after reading about the topic, my own experiences with the main modality that is considered evidence-based (CBT), and my own experiences with my therapist while seeing him for trauma and depression. That being said, CBT might be the perfect thing for another client; we're all different people after all.

Here's a good article that lays out some of the problems with evidence-based psychotherapy.
