Tables 7.18 and 7.19 present, in alphabetical order, the unweighted and weighted
interview response rates for each State by age group. Both tables are presented on each State's
page. Similarly, Tables 7.20 and 7.21 show national and State results of incomplete interviews
by age, while Tables 7.22 and 7.23 contain interview refusal reasons by age group for the Nation
and for each State.
Remaining interview result tables are presented in pairs with the first table providing the
unweighted percentages and the second table providing the weighted percentages. Tables 7.16
and 7.17 show the interview response rates by age group and gender. More detailed information
by gender and smaller age groups is shown in Tables 7.24 and 7.25. Tables 7.26 and 7.27 present
a summary of the interview response rates broken down by several factors including race, type of
county, geographic region, and gender.
7.4 Spanish Interviews
The percentages of completed interviews that were conducted in Spanish are shown by
State in Table 7.28 (unweighted) and Table 7.29 (weighted). Spanish interviewing percentages
also were analyzed by age and county type in Table 7.30 (unweighted) and Table 7.31
(weighted). Table 7.32 presents the number of English- and Spanish-version interviews
conducted by region and by population density.
7.5 Interviewer Assessment of the Interview
As part of each computer-assisted interviewing (CAI) interview, field interviewers (FIs)
were required to assess the respondent's level of cooperation, understanding, and privacy during
the interview. FIs also were asked to record whether the respondent needed assistance during the
audio computer-assisted self-interviewing (ACASI) questions and what type and amount of
assistance the FI provided. Other questions asked whether the laptop seemed to influence the
respondent's choice to participate, and if respondents revealed to the FI answers entered during
the ACASI section.
All of these data were captured in the FI Observation Questions at the end of the
interview and are summarized in Tables 7.33 through 7.38. Table 7.33 shows the FI's assessment
of the need to provide assistance to respondents in the ACASI section. Tables 7.34 through 7.38
present data based on the FI's assessment of the respondent's level of understanding of the
interview, the respondent's cooperation during the interview, the level of privacy during the
interview, how the laptop influenced participation, and finally how often the respondent revealed
answers in the ACASI section. Each of these tables is broken down by age and race/ethnicity.
7.6 Number of Visits
FIs were required to make at least five visits to DUs when attempting to complete
screening and interviewing. In reality, callbacks continued to be made as long as the field
supervisor (FS) felt there was a chance that the screening or the interview could be completed in
a cost-effective manner. In some cases, more than 10 visits were made to complete a screening or
interview. Tables 7.39 and 7.40 present data on the number of visits required to complete
screenings and interviews.
