As a general rule, long questionnaires get less
response than short questionnaires. However, some studies
have shown that the length of a questionnaire does not
necessarily affect response. More important than length
is question content. A subject is more likely to respond
if they are involved and interested in the research
topic. Questions should be meaningful and interesting to
the respondent.
When conducting Internet surveys, try to make the pages short enough
so they appear in one screen that requires minimal scrolling.
Respondents answers are recorded only when a submit button is pressed.
If your pages are too long, and the respondent doesn't complete a page,
their answers for that page will not be captured.
