This technical report presents the development and validation of the SUPR-Qm V2, a streamlined version of the Standardized User Experience Percentile Rank Questionnaire for Mobile Apps. The report outlines the analysis conducted on large-sample datasets to replicate the Rasch model from the original SUPR-Qm published in 2017. It details the process of identifying redundant items from the original 16-item questionnaire, resulting in a concise 5-item version. The stability of both the SUPR-Qm and SUPR-Qm V2 is demonstrated over two multiyear data collection periods involving 155 mobile apps across 23 industries. Additionally, the report discusses the development of interpretive norms for both versions, including curved grading scales, enhancing their utility for UX practitioners and researchers. The SUPR-Qm V2 is designed to provide a quick and easy-to-interpret measure of user experience for mobile applications, ensuring its relevance and applicability in the field.
