5.1.1. User-Controlled Skips in Scrolling Designs generate, create none none in none projects Use QR Codes safely User-controlled none none skips in scrolling surveys resemble those in paper questionnaires in that they are visible to the respondent and require the respondent to take some action to comply with the instruction. The belief is that such skips should be as simple as possible I say belief because I know of no studies that have examined the effect of skip complexity on compliance with the instructions. But it is good advice nonetheless.

In practice, user-controlled skips are generally restricted to the simple conditionals identi ed earlier and illustrated in Figure 5.2. While they resemble those in paper surveys, skips in static or scrolling Web surveys present different design challenges.

Many of the visual cues available to the designer in paper surveys (such as the arrows in Figure 5.2) are harder to implement in a consistent manner on the Web. An example from Tourangeau, Couper, Galesic, and Givens (2004) is presented in Figure 5.

3. This design had to be accomplished using table elements in HTML to control the position of the brace brackets. While the braces may work on paper and under ideal testing conditions on the Web, as soon as the respondent resizes the browser or change the font size, the relationship of the elements could be disturbed.

This is why trying to replicate paper skips on the Web using symbolic language (Redline and Dillman, 2002) is generally quite dif cult. An exception, shown in Figure 5.4, is from the 2001 Norwegian Census (Haraldsen, Dale, Dalheim, and Str mme, 2002).

Here, the arrow symbols used, and their position relative to the response options, are unaffected by changes in the browser settings. But this works only for relatively simple skip instructions..

Look at the example in Figure 5.5. The skip instructions could be accomplished with brace brackets and/or arrows on a paper questionnaire, but as already noted, these are dif cult to do on the Web.

The result is a question that looks much more complex than it need be. Turning this into a paging design would eliminate all the skip instructions. A more common alternative is to include a skip instruction as a hypertext link, which on being clicked, simply jumps the respondent lower down in the same.

Using hyperlinks to navigate a page is a standard HTML feature that does not require active content, and the function should be familiar to most users of the Web. This is illustrated in Figure 5.6.

The design challenge is to render the link in such a way that it is clicked after the respondent has selected the appropriate response. In other words, it must be visible enough that they notice it, but not too visible that they do so before answering the question, as Dillman (2000, p. 395) has noted.

How much of a problem, if at all, is such premature skipping I ll address the research on this issue in Section 5.1.4.

. 5.1.2. System-Controlled Skips in Scrolling Designs An alternative in scrolling surveys is to use client-side scripts to gray out or deactivate the inappropriate items. This can be done using JavaScript, for. Figure 5.6 Use of Hyperlink for Skip in Scrolling Survey.

While it is very dif cult to change page content (i.e., the wording of questions) using client-side scripting, formatting changes such as font color are less dif cult.

This feature of JavaScript is used to control the ow of the survey in Figure 5.7. Given that the no response was chosen in Question 9, the items in Question 10 are made inaccessible.

They are still visible, but clicking on them will have no effect. If the no was switched to a yes in Question 9, the items and response options in Question 10 would change to a normal font and be active. In the only known study of this approach, Kjellstrom and B lter (2003) conducted a smalla scale usability study with 19 users, and found that users spent a lot of time and energy trying to read the gray text, and consequently paid less attention to the question.

They recommend against this approach..
