Background: Public involvement in research to improve data quality and to empower different stakeholders is good scientific practice, but rarely implemented across all research phases. Objective: This article reports on an attempt to involve members of a self‐help group for relatives of people living with dementia as co‐researchers in the data analysis in a short‐term format. Methods: One researcher identified statements about assistive technologies from 17 interviews with people living with dementia and informal caregivers.
