ORGANIZING AND DESIGNING QUESTIONNAIRES 309<br />

<strong>Asking</strong> Identical <strong>Questions</strong> About Multiple Household<br />

Members or Events<br />

We have already pointed out that asking the same question about<br />

all household members or events is easily handled in computerassisted<br />

interviewing using the rostering capabilities of the program.<br />

Such questions on paper forms are very difficult for respondents and<br />

are prone to significant errors by interviewers even after careful<br />

interviewer training.<br />

If used, however, these questions are usually formatted by having<br />

the question on the left and a series of parallel columns for each<br />

household member or event. If necessary, this series can extend to<br />

facing pages. This format is sometimes shifted ninety degrees, that<br />

is, the questions appear across one page or two facing pages, and the<br />

persons or items are listed from top to bottom at the left. This format<br />

would be used instead of the other when the number of persons<br />

or items exceeds the number of questions asked about each.<br />

Some studies may require either more questions or more items<br />

than can fit on two facing pages. Although the number of questions<br />

is known in advance, the number of items (persons or events) will<br />

vary from household to household. Again, this situation lends itself<br />

to computer-assisted interviewing. If paper is used, two basic strategies<br />

are possible: using supplementary forms or making the basic<br />

form larger. Thus, even though most households have fewer than<br />

six members, some may have as many as twelve or more. <strong>The</strong> basic<br />

form could be made sufficiently large to record information about<br />

twelve members, or the basic form could have room for only six<br />

household members and supplementary forms would be used for<br />

additional members. Supplementary forms are more flexible and<br />

reduce the size of the basic paper form, but they can sometimes get<br />

separated. <strong>The</strong>y also require that the interviewer be able to locate<br />

the necessary forms while the interview is in progress. Although<br />

one supplementary form is not too difficult to handle, the task<br />

becomes more burdensome if the interviewer must sort among
