Abstract

This study explores validity, reliability, and factor analysis of the Quebec User Evaluation of Satisfaction with Assistive Technology (IT-QUEST) for users of assistive technology devices in an Italian population. It was administered to 75 people to determine which of the 24 original items were relevant to the Italian context using exploratory and confirmatory factor analyses (EFAs and CFAs) were conducted with internal consistency and test-retest reproducibility also evaluated. The EFA and CFA showed that the 24-item survey may have limited relevance to the Italian context. We individuated 12 significative items, divided into two subscales, as well as the original validation. The test-retest showed high values of the Intraclass Correlation Coefficient (ICC) (0.7–0.9), with a 0.812 ICC for the total scale providing support and evidence for Italian professionals to evaluate user satisfaction with assistive technology devices. This research also lays the foundation for developing a validation study of the IT-QUEST 2.0 that is relevant to the Italian culture. Further research may investigate psychometric properties involving more participants and different users of assistive technology devices.
