Abstract: Background: As people with intellectual disabilities (ID) today live integrated in society and use different technological artefacts and services in their everyday life, more in‐depth evaluation methods are crucial to detect strengths and limitations of their everyday technology use. The Everyday Technology Use Questionnaire (ETUQ) was originally designed to investigate the extent to which older adults with cognitive limitations can use the everyday technology that is of relevance to them. The purpose of this study was to explore and evaluate evidence of the validity of ETUQ among adult persons with ID. Methods: The original 93‐item ETUQ was used to interview 120 adult participants with ID, recruited from a region in northern Sweden. A Rasch model was used to analyse the psychometric properties of the rating scale, scale validity, person response validity and person separation. Results: The ETUQ rating scale displayed sound psychometric properties when used with this sample. The goodness‐of‐fit statistics showed that 15 (16%) of the 93 items demonstrated higher values than expected. A step‐by‐step removal process of items not demonstrating fit to the model resulted in an ETUQ version with 46 items (49%) that met all the criteria for scale validity. Fifteen participants (12%), primarily with mild ID, still demonstrated a higher number of unexpected responses included in ETUQ. Conclusions: The results of this study indicate that the ETUQ generates a valid measure of perceived difficulty in using everyday technology including adult persons with ID.
