Streamlining the SUPR-Qm: The SUPR-Qm V2
Abstract The SUPR-Qm is a standardized questionnaire for the assessment of the UX of mobile apps. In this paper, we describe our analysis of large-sample datasets to (1) replicate the Rasch model reported in the initial publication of the SUPR-Qm in 2017, (2) identify redundant items from the original 16-item SUPR-Qm that could be removed […] [Read More阅读详情자세히 읽기Leia mais続きを読むLeer más]
[:en]Comparison of Select-All-That-Apply Items with Yes/No Forced Choice Items [:]
[:en] Abstract Prior research has suggested that people tend to select more items when presented with a forced choice (yes/no) format than with a select-all-that-apply (SATA) format, and some have argued against ever using SATA in research. We review findings from previous research and report the results of new studies comparing a standard SATA grid […] [Read More阅读详情자세히 읽기Leia mais続きを読むLeer más]
Item Benchmarks for the System Usability Scale
Abstract From humble beginnings, the SUS has become a valuable tool in the toolkits of usability and user experience practitioners and researchers. We have developed regression equations that compute benchmarks for SUS items based on an overall SUS score. A review of the SUS literature on published benchmarks for the means of overall SUS scores […] [Read More阅读详情자세히 읽기Leia mais続きを読むLeer más]
SUPR-Qm: A Questionnaire to Measure the Mobile App User Experience
Abstract In this paper, we present the SUPR-Qm, a 16-item instrument that assesses a user’s experience of a mobile application. Rasch analysis was used to assess the psychometric properties of items collected from four independent surveys (N = 1,046) with ratings on 174 unique apps. For the final instrument, estimates of internal consistency reliability were […] [Read More阅读详情자세히 읽기Leia mais続きを読むLeer más]
Can I Leave This One Out? The Effect of Dropping an Item From the SUS
Abstract There are times when user experience practitioners might consider using the System Usability Scale (SUS), but there is an item that just doesn’t work in their context of measurement. For example, the first item is “I think I would like to use this system frequently.” If the system under study is one that would […] [Read More阅读详情자세히 읽기Leia mais続きを読むLeer más]
Revisiting the Factor Structure of the System Usability Scale
Abstract In 2009, we published a paper in which we showed how three independent sources of data indicated that, rather than being a unidimensional measure of perceived usability, the System Usability Scale apparently had two factors: Usability (all items except 4 and 10) and Learnability (Items 4 and 10). In that paper, we called for […] [Read More阅读详情자세히 읽기Leia mais続きを読むLeer más]
The Challenges and Opportunities of Measuring the User Experience
Not too long ago it seemed the biggest challenge facing companies was justifying any investment in usability and the user experience (Bias & Mayhew, 2005). While that has not entirely gone away, increasingly I see organizations facing a new challenge. Instead of worrying about how to justify any investment in the user experience, the shift […] [Read More阅读详情자세히 읽기Leia mais続きを読むLeer más]
