I answered "Not sure" because obviously giving feedback is important but when it is something structured and regular then I'm not sure in its value anymore because then it most likely just becomes a formality.

So, if my T would ask me to fill in some kind of questionnaire or propose to talk about our progress without necessitating context then I would just refuse and if he would propose it ever again then I would probably fire him because for me that would be evidence that he is not the kind of therapist I need.

I don't believe in formal progress reports in therapy, because I think people mostly don't even know themselves what are they really working in on therapy. That's why I also don't believe in concrete therapy goals and I would never work with a T who would insist to agree certain goals and who would want to monitor the progress towards these goals.
