dc.description.abstractThe System Usability Scale (SUS) is a non-proprietary and technology-agnostic instrument that measures the subjective usability of products and systems. Besides its popularity in the English Human Factors community, the SUS has also been translated to other languages such as Mandarin (Sheu, Fu, & Shih, 2017) and Polish (Borkowska & Jach, 2017). Although past research has demonstrated the reliability and validity of the SUS in some languages, methodology of validating translation was inconsistent between languages. This project aims to address this issue by translating and validating the SUS in multiple languages systematically. Native speakers of Arabic, Chinese, French, German, Hindi, and Spanish were recruited on Prolific.ac to evaluate five everyday products on the translated SUS. Evidence of scale reliability and validity was found in Chinese, French, German and Spanish SUS, with Cronbach’s alpha > 0.8 and significant correlations between SUS and an adjective rating scale (r between .54 and .74). Sensitivity of the SUS was also demonstrated via significant t-tests on the SUS scores between products. A principal axis factor analysis revealed a one-factor model with mediocre to poor model fit. Overall, the Chinese, French, German and Spanish SUS can be used with confidence to measure the usability of everyday products and systems, and larger sample sizes are required to fully investigate the psychometric properties of the Arabic and Hindi SUS.en_US
