Abstract
This paper aims to adapt and validate the User Experience Questionnaire Plus (UEQ+) in the Indonesian context. The UEQ+ is a modular extension of the User Experience Questionnaire (UEQ), which has been adapted to the Indonesian context and used in many studies. The UEQ+ was originally developed in German and English. As a modular extension, the UEQ+ has more user experience (UX) scales compared to the UEQ and can be used to evaluate products in special scenarios. Several steps were carried out to adapt and validate the UEQ+: translating the questionnaire into Bahasa by involving UX practitioners, evaluating the translation results by involving a UX expert and practitioners, and conducting face validity and reliability testing through two case studies (Zoom and Learn Quran Tajwid as online learning tools). The results showed that the findings from the open-ended questionnaire were consistent with the results of the six scales. Future work is needed to investigate whether the UEQ+ can capture some of the UX-related themes identified from the two case studies.
