Design of Web Surveys
Principles of Design for Web Questionnaires (Dolman, Tortora, Bowker)
• Welcome screen• First question should be easy to answer,
but interesting• Conventional format similar to paper• Limit line length• Provide instructions for computer
actions

• Instructions with individual questions, not at the beginning
• Do not force answers unless necessary• Scrolling• Progress bar
Principles of Design for Web Questionnaires Dillman, Tortora(, Bowker)
• Screen by screen– Only one question per page, respondent must
answer the questions before they can continue
• Scrolling – Respondent can see, if not the entire questionnaire,
more than one question.
