How to best present a series of filter items and the sets of follow-up items conditional on each filter has been a recurring questionnaire design challenge in self-administered surveys, and to a lesser extent, interviewer-administered surveys. Two approaches are commonly used: Ask all the filter questions first, then instruct respondents to complete one set of conditional questions for each filter question they previously endorsed (―grouped‖ structure). The second approach is to ask one filter question at a time, and use branching instructions and visual cues to immediately answer or skip over the corresponding follow-up items (―sequential‖ structure). Each navigational approach may have implications for visual design, respondent conditioning, perceptions of burden, and satisficing behavior. Using CATI-like navigation programming, web surveys can employ a hybrid approach: Filter questions using hyperlinks that, when the response condition is met, immediately open popup subforms with follow-up questions, and upon sequential completion of that filter‘s set of follow-ups, return the respondent to the list of filter questions. One advantage of this hybrid approach is that respondents see a short, uncluttered list of filter questions, without skip patterns, as in the grouped approach, but also can be sequentially presented with applicable follow-up questions immediately, avoiding the need to recall answers to earlier filter questions. The implementation of this approach in one web survey interface, however, produced patterns of item nonresponse and suboptimal navigational behavior that reinforce several textbook principles of questionnaire visual design and usability. The response effects are described, and possible remedies suggested.
