AN AFTER-SCENARIO QUESTIONNAIRE FOR USABILITY STUDIES
James R. Lewis · ACM SIGCHI Bulletin · 1991
The purpose of this report is to (1) describe a psychometric evaluation of a printer scenario questionnaire (PSQ) that was used to assess user satisfaction during scenario-based usability studies of printers and (2) compare the psychometric properties of the PSQ with those of the After-Scenario Questionnaire (ASQ) (Lewis, 1991b). The PSQ is similar to the ASQ, but is composed of three five-point scales rather than three seven-point scales.
