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

Abstract

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. IMPLICATIONS FOR REHABILITATION The Italian version of the QUEST 2.0 (QUEST-IT 2.0) in now available and health professionals can use it with more confidence. The QUEST-IT 2.0 is a valid and reliable assessment tool when used with a sample of assistive mobility device users.
