Measuring Respondent Privacy Concerns Cognitive Interviews

Submitted Under Generic Clearance for Questionnaire Pretesting



Request: The Census Bureau plans to conduct additional research under the generic clearance for questionnaire pretesting research. We will be conducting cognitive interviews to aid in the development of a questionnaire to evaluate respondent privacy concerns for the 2020 Census.


Purpose: The purpose of this cognitive research is to (1) evaluate the effectiveness of the draft questionnaire for measuring respondent privacy risk tolerance in the context of the 2020 Census and (2) identify potential improvements to the draft questionnaire items.


The full questionnaire is attached (see Attachment I: Respondent Privacy Concerns Questionnaire). We intend to administer an abbreviated decennial census questionnaire to respondents, followed by a series of privacy risk perception questions developed by our research team (and updated iteratively throughout the interview period as needed). Once respondents complete the entire questionnaire, we will probe them about their responses to and interpretation of the privacy risk perception questions. By combining the responses across interviews and making iterative changes to the questionnaire as necessitated by respondent feedback, we can evaluate the strengths of the draft questionnaire and identify any potential problems in terms of respondent comprehension or interpretation. The results of the cognitive testing will be used to design a field test to quantitatively measure individuals’ privacy risk tolerance with the goal of informing the privacy loss budgets allowed in mathematical privacy models for decennial data releases.


Population of Interest: Residents of the United States and its territories.


Timeline: From September 2017 to February 2018, staff from the Center for Survey Measurement will conduct an iterative series of cognitive interviews with up to 40 respondents. As needed throughout the interview period, CSM staff will update the draft questionnaire and interview materials to address feedback from respondents.


Sample: We will conduct the interviews with a total of up to 40 respondents using printed copies of the draft questionnaire (to be updated iteratively based on respondent feedback during the course of the interview period).


Our recruiting efforts will aim for diversity on characteristics believed to be related to privacy attitudes and concerns:

 

  • Geography

  • Age

  • Education and use of federal statistics

  • Device ownership and level of internet use


Recruitment: Respondents will be recruited through fliers posted at local community organizations; advertisements on Craigslist.com; and broadcast messages distributed through the Census Bureau’s daily online newsletter. All recruiting materials are attached (see Attachment II: Recruitment Advertisements).


Location of Interviews: Interviews will be conducted at the Census Bureau’s Response Research Laboratory and at locations convenient to interviewees. The interviews will be conducted in-person in the local metropolitan area (DC, Maryland, Virginia), and possibly in nearby Delaware, West Virginia, Pennsylvania, and New Jersey as well.


Protocol: We will conduct our cognitive interviews using printed versions of the draft questionnaire. We intend to administer an abbreviated decennial census questionnaire to respondents, followed by a series of privacy risk perception questions developed by our research team. We will ask respondents to think aloud about their reaction to the privacy risk perception questions. Once respondents complete the entire questionnaire, we will probe them about their responses to and interpretation of the privacy risk perception questions. General probes will be asked at the end during respondent debriefing (see Attachment III: Privacy Concerns Questionnaire Cognitive Interview Protocol).


Informed Consent: We will inform participants that their response is voluntary and that the information they provide is confidential and will be accessed only by employees involved in the research project. The consent form will also indicate that the respondent agrees that the interview can be audio-taped to facilitate analysis of the results. Participants who do not consent to be audio-taped will still be allowed to participate.


Incentive: Participants will receive $40 for their participation in this research. A copy of the consent form is attached (see Attachment IV: Consent Form).


Length of Interview: We estimate that each of the 40 interviews will take approximately one hour for a total of 40 hours. The pre-approved generic screening questionnaire will take approximately ten minutes per person, and the additional screening questions specific to this research will take two minutes per person (see Attachment V: Recruitment Eligibility Screeners).


We estimate that we will screen three people for each successful recruit for each of the 40 interviews. Therefore, for the first round of interviewing, we estimate a total of 120 people screened for a total of 4 hours (120 people at 2 minutes each). Thus, the total estimated burden of this research is 44 hours.
