Standardized User Experience Percentile Rank Questionnaire
What is it?
SUPR-Q measures the user's attitudes toward the quality of a experience in a digital product, including usability.
How it Works?
Is an eight-item questionnaire that uses a five-point Disagree to Agree scale (1 = Strongly Disagree and 5 = Strongly Agree).

If you have a score of 50%, your website ranks as average. A score of 25% means your website ranks below average, while a score of 75% ranks above average.

What Measures?
It measures:

  • Usability
  • Trust
  • Loyalty
  • Appearance

What are the Pros and Cons?
  • The SUPR-Q has two items per factor, so with eight items, you get four constructs. What's more, with the same eight items you can estimate the SUS highly accurately and generate the NPS, making the SUPR-Q very efficient.
  • You can predict SUS scores from the SUPR-Q.
  • SUPR-Q measures more than usability.

  • Don't have a free normed database of scores;
  • Complex scoring method promising mistakes
