Initial Co‐Design Development of a Questionnaire to Measure Patient Preferences in a Danish Mental Healthcare Setting

This study was co-designed in collaboration with individuals with lived experience of mental illness. A co-researcher with lived experience was involved throughout several stages of the research process, including the design and facilitation of workshops, recruitment of participants, and interpretation of findings. Additional 15 co-designers with lived experience were engaged in two workshops, contributing actively to the generation, refinement, and validation of questionnaire items. Their insights ensured that the tool reflects the values and preferences of those it aims to serve. Peer workers, clinicians, and researchers also supported the co-design process, helping facilitate workshops and integrate experiential and academic perspectives.
