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.
本研究探讨了魁北克辅助技术用户满意度评估量表（IT-QUEST）在意大利人群中辅助技术设备使用者的效度、信度及因子分析。该量表施测于75人，通过探索性因子分析和验证性因子分析（EFA和CFA）来确定24个原始项目中哪些与意大利背景相关，同时还评估了内部一致性和重测信度。EFA和CFA表明，24项调查问卷与意大利背景的相关性可能有限。我们确定了12个有意义的项目，分为两个子量表，以及原始效度指标。重测结果显示组内相关系数（ICC）值较高（0.7 - 0.9），总量表的ICC为0.812，为意大利专业人员评估用户对辅助技术设备的满意度提供了支持和证据。本研究还为开展与意大利文化相关的IT-QUEST 2.0效度研究奠定了基础。进一步的研究可以调查涉及更多参与者和不同辅助技术设备使用者的心理测量特性。
