Introduction

According to Perlman (2009), “Questionnaires have long been used to evaluate user interfaces (Root & Draper, 1983). Questionnaires have also long been used in electronic form (Perlman, 1985). For a handful of questionnaires specifically designed to assess aspects of usability, the validity and/or reliability have been established, including some in the [table below].” (retrieved 20:56, 14 March 2011 (CET))

List of usability and user experience questionnaires

User Interface Usability Evaluation with Web-Based Questionnaires

Author: Gary Perlman (2009)

Available through the User Interface Usability Evaluation with Web-Based Questionnaires page, either as online interface or as a a set of Perl scripts that you can install in your own server. (also from: online service at hcbib.org)

The script creates a customizable Web-based perl CGI script that allows to administer and to collect data according to a few "standard" user interface evaluation questionnaire forms. The questionnaires may be applied to web sites, but also to other software.

Online service: http://hcibib.org/perlman/question.cgi. It will send results by email.

Before you just click on the above link or the links below you should go to the original page at hcibib, scroll down and configure the questionnaire, i.e.:

• customize system name, administrator email, etc.
• customize rating scale such as number of points, labels, ...
• customize number of open-ended positive/negative comments requested
• Select the questionnaire, i.e.

Below we reproduce the table from the original keeping the original links.

This page seems to be the best starting point for exploring well known web-based usability evaluation questionnaires.

Purdue Usability Testing Questionnaire (PUTQ)

Measuring Usability with the USE Questionnaire

Author: Arnold M. Lund, Measuring Usability with the USE Questionnaire, STC Usability SIG Newsletter, orginally published in the October 2001 issue (Vol 8, No. 2)

Available: Measuring Usability with the USE Questionnaire

The questionnaire was developed over time and it started out with a large pool of items. “The questionnaires were constructed as seven-point Likert rating scales. Users were asked to rate agreement with the statements, raging from strongly disagree to strongly agree. Various forms of the questionnaires were used to evaluate user attitudes towards a variety of consumer products. Factor analyses following each study suggested that users were evaluating the products primarily using three dimensions, Usefulness, Satisfaction, and Ease of Use.”

The questionnaires were constructed as seven-point Likert rating scales, e.g. from -3 (totally disagree) to +3 (totally agree)
