Reliability and validity of the Italian version of Quebec User Evaluation of Satisfaction with Assistive Technology 2.0 (QUEST-IT 2.0) with users of mobility assistive device

Objects: The aim of the study is the translation, culturally adaptation and validation of the Italian version of Quebec User Evaluation of Satisfaction with Assistive Technology 2.0 (QUEST-IT 2.0) in an Italian population with users of mobility assistive device, through a cross sectional study. Materials and methods: To evaluate internal consistency and test-retest reliability, Cronbach's? and Intraclass Correlation Coefficient (ICC) were respectively calculated. The WheelCon-M is administered together, and Pearson's correlation coefficient was calculated for validity. Results: The scale was submitted to 130. The mean QUEST-IT 2.0 score in this study was 37.39 +/- 9.35. Cronbach's? was 0.740 (p < 0.01) and ICC was 0.853 and >0.994 in each domain. The correlation with WheelCon-M short form a was 0.30 (p < 0.05). Conclusions: the QUEST-IT 2.0 showed out good consistent results for reliability and validity. This scale will be very useful for doctors, researchers and occupational therapist in the valuation and management of mobility assistive device.
