Abstract
<jats:title>Abstract</jats:title> <jats:p>In this chapter, the authors describe the practice research program for Norse Feedback (NF). They explain why and how NF, a comprehensive monitoring and feedback system for psychosocial interventions, was developed through participatory methods. Originating in Norway and used across various clinical settings, NF was co-developed and researched in collaboration with therapists, clients, and other clinical stakeholders. The authors illustrate how, using a framework of participatory action research, they initiated a research and development process that ran in parallel with real-world implementation. Together with their partners, they co-designed the methods, structure, and processes needed for continuous refinement of the system. The chapter details NF’s role in assessing a wide range of constructs in clinical practice. They present qualitative and quantitative studies that provide practice-based evidence from adults and adolescents, including those dealing with substance abuse. By integrating the perspectives of both clients and therapists, the authors suggest that collaborative efforts can drive meaningful improvements in treatment. They aim to show how a collaborative approach to research and development, where stakeholders are not just participants but co-creators, has helped define and operationalize therapy processes and outcomes that matter for routine monitoring and feedback systems.</jats:p>
