Usability Evaluation (Us.E.)

Usability Evaluation (Us.E.) is a multidimensional questionnaire aimed at assessing website usability. The questionnaire has been developed by Francesco Di Nocera, Fabio Ferlazzo e Paolo Renzi (Department of Psychology, Sapienza University of Rome, Italy) in 1997, although the questionnaire itself was publicly presented only in 1999. Its early edition (Us.E 1.0) was a 70-item questionnaire, whereas its final form (Us.E. 2.0) is a 19-item questionnaire subdivided in three subscales representing the cognitive framework users would adopt for evaluating the quality of their interaction with the interface:
Us.E. 2.0 allows fast assessment of web site usability identifying critical issues that could be eventually addressed by re-design. Users are required to answer to all items along a 5-point Likert scale (ranging from "strongly agree" to "strongly disagree"). In order to obtain stable usability estimates a minimum of 30 respondents are required.
Conditions of use.
Us.E was born as a research tool and it is freely available to the scientific and professional community (CC BY-ND license). The questionnaire is available in Italian and English.
