Psychometric Evaluation of the F-SUS: Creation and Validation of the French Version of the System Usability Scale

ABSTRACT While the System Usability Scale (SUS) is probably one of the most widely used questionnaires to measure the perceived ease of use of interactive systems, there is currently no scientific valid translation in French. This article describes the translation and statistical validation of the French version of the SUS, called F-SUS. On the basis of two translations carried out by a committee of bilingual experts, the various psychometric analyses made it possible to select only one translation. Fidelity measurement, factor analysis and sensitivity measurement obtained results very close or similar to the original version of the SUS. Thus, the F-SUS can be used with confidence by French-speaking usability researchers and practitioners.
