The System Usability Scale PDF Generator

The System Usability Scale (SUS) PDF generator is a client-side-only JavaScript web application that allows for the generation of interactive PDF questionnaires for the System Usability Scale by John Brooke (1996) and is part of the free, open source System Usability Scale Analysis Toolkit. While the SUS is one of the most widely used usability questionnaires and multiple validated and non-validated translations exist, it is often challenging to distinguish versions, evaluate their origin and validity, or to create correct questionnaires based on the available sets of questions. This tool combines 20 of the available (validated and non-validated) versions and langauges of the SUS questionnaire into the SUS PDF Generator. It allows researchers and usability practitioner to quickly create interactive SUS questionnaires, provides insights into the origin, reliability and validity of the used variant/langauge and enables them to use custom variable descriptors like product, system or the products name in the generated questionnaires.

Using the SUS PDF Generator

The SUS PDF Generator is hosted on http://pdf.sus.tools/ and automatically deployed on changes to the main branch. Questionnaire versions and translations are each stored as .json files, containing: The questionnaire title, likert-scale descriptions, the 10 SUS questions, the source and authors of the version, and generator hints on the versions origin, relibaility and validity:

• Languages\English (revised).json based on Bangor et al. (2008)
• Languages\English (original).json based on Brooke (1996)
• Languages\English (non-alternating).json based on Sauro et al. (2011)
• Languages\English (simplified).json based on Holden (2020)
• Languages\English (simplified, for children 7-8).json based on Putnam et al. (2020)
• Languages\English (simplified, for children 9-11).json based on Putnam et al. (2020)
• Languages\German.json based on Gao et al. (2020)
• Languages\German (SAP).json by Reinhardt et al. (2013)
• Languages\French.json based on Gao et al. (2020)
• Languages\French (literary).json by Gronier et al. (2021)
• Languages\Italian.json based on Borsci et al. (2009)
• Languages\Turkish.json based on Demirkol et al. (2018)
• Languages\Polish.json based on Borkowska et al. (2016)
• Languages\Spanish.json based on Gao et al. (2020)
• Languages\European Portuguese.json based on Martins et al. (2015)
• Languages\Dutch.json based on Ramratan (2010)
• Languages\Dutch (simplified, for children 9-11).json based on Arztmann et al. (2022)
• Languages\Swedish.json based on Göransson (2001)
• Languages\Slovene.json based on Blažica et al. (2014)
• Languages\Danish.json based on Hvidt et al. (2019)

Contributing to the SUS PDF Generator

The SUS PDF Generator is envisioned as a participatory project, continously improving and expanding it's quality and scope. Feel free to contribute changes or additional versions/languages. If you find errors, please report them through opening an Issue or directly correct them in the corresponding .json file, if possible. Translations, versions and variants we are aware of that are currently not included in the tool are the following:

• Persion from Dianat et al. (2014)
• Indonesian from Sharfina et al. (2016)
• Malay from Marzuki et al. (2018)
• Arabic from Gao et al. (2020)
• Arabic from AlGhannam et al. (2018)
• Chinese from Gao et al. (2020)
• Hindi from Gao et al. (2020)
• Urdu from Anam et al. (2020)
• Greek from Katsanos et al. (2012)
• American Sign Language from Huenerfauth et al. (2017)

Additionally, some translations, like the ones by Gao et al. (2020), also include usage instructions at the top of the questionnaire. As this was not present in the original SUS and most translations do not include them, they are not available in the tool. We might add them later as another option.
