Telephone interviews conducted in English and Spanish under the direction of Princeton Survey Research Associates International
Sampling Procedures
Interviews were conducted over the phone using a combination of landline and cell random digit dial (RDD) samples. Both samples were disproportionately stratified to increased the incidence of African-American and Hispanic respondents. Additionally, all interviews were conducted using a Computer Assisted Telephone Interviewing (CATI) system to ensure proper question sequence and skip patterns.
The survey questionnaire included a split form design whereby participants were randomly assigned to one of two subsets of questions, creating two simultaneous surveys. 1,944 adults were asked one subset and 2,012 adults were asked the other. Each of these subsets is weighted separately to represent U.S. adults. Questions asked on both forms can be combined to create a representative survey of U.S. adults with the full 4,006 respondents.
