Feedback Informed treatment (http://socialstyrelsen.dk/tvaergaende-omrader/dokumenterede-metoder-voksne-og-handicap/om/feedback-informed-treatment-fit) is not a treatment method in and of itself. Rather, it is a method to evaluate systematically, if any given person is benefitting from the treatment this person is receiving.
At the beginning of each session, there is a check in about the past week. At the end of each session there is an evaluation of how the session has been.
I am a qualified supervisor in the method and teach how to use it.
