Cross-Cultural Validation of Quebec User Satisfaction with Assistive Technology 2.0 for Spanish Population (QUEST-2.0 ES)

Background: Assistive technologies (ATs) are resources to promote the independence and participation of people with a disability. The use of standardized tools, based on outcome measures, is essential for guaranteeing high-quality rates. The Quebec User Evaluation of Satisfaction with AT–2.0 (QUEST) is a scale to assess the satisfaction of people using any AT. Objectives: To translate and culturally validate the QUEST–2.0 for the Spanish population (QUEST 2.0-ES). Methods: A validation cross-design and descriptive study. The test–retest reliability, validity, and internal consistency of QUEST 2.0-ES were studied. It was divided into two phases: Sample 1 was formed by 26 persons; in sample 2, 30 persons participated. The conditions included neurological conditions, amputations, rare diseases, and deafness. Results: Thirty-five men and 21 women participated in total. The majority of AT used were those for mobility. QUEST 2.0-ES analysis showed internal consistency values between the test (α = 0.87) and retest versions (α = 0.89). The internal consistency was high for AT (test, α = 0.83; retest, α = 0.87) and Service (test, α = 0.80; retest, α = 0.80). The temporal reliability (1–2 weeks) for test–retest was 0.88. Conclusion: QUEST 2.0-ES showed good psychometric properties in terms of validity and test–retest reliability, and it is a good tool to assess the user’s satisfaction with ATs and services.
