Low Boom Questions

1

QUESTIONNAIRE

Four slight variants of the same interview are shown in the tables below:

• I: Live agent contact attempts to presumed landline sample records
  (telephone numbers)

• II: Live agent contact attempts to known wireless sample records
  (telephone numbers)

• III: Automated contact attempts to presumed landline sample records
  (telephone numbers)

• IV: Automated contact attempts to known wireless sample records
  (telephone numbers)

The variant forms of the questionnaires differ in whether an age-ineligible respondent is asked if another adult household member is available for interview, and in the manner in which additional information about the interview is offered to respondents.

In all cases, tri-tone intercepts (disconnected or otherwise non-functional numbers), fax/modem numbers, busy signals, no answers, refusals, and abandoned interviews (break-offs/incompletes/hang ups) are automatically dispositioned by the IVR and CATI software, without any interviewer involvement. Likewise, all responses are automatically timed, dated, coded and immediately entered by anonymous case number into databases of questionnaire responses. Only the verbiage shown in quotation marks in the tables below is heard by respondents.

The wording of questionnaire items is presented in electronic form (i.e., on a display screen) for live agent interviewers to read to respondents. Recordings of questionnaire items are automatically reproduced to respondents. In no case are paper versions of the forms shown below involved in the actual administration of interviews.

The flow of questioning is sequential unless otherwise indicated in the last (NEXT ITEM/ACTION) column of the tables. Shaded areas in the following tables concern preliminary qualification of potential respondents, not their responses to questions. Substantive questionnaire items are shown in unshaded areas.
