Summary
SSRS conducted a survey of Muslims, Jews and the General Population for the Institute for Social Policy and Understanding from January 8 through January 28, 2019. The study investigated the opinions of Muslims, Jews and the General Population regarding the government, the most important issues facing the country, faith customs and religious/race/gender discrimination.
CATI interviewers received written materials about the survey instrument and received formal training for this particular project. The written materials were provided prior to the beginning of the field period and included an annotated questionnaire that contained information about the goals of the study as well as, detailed explanations as to why questions were being asked, the meaning and pronunciation of key terms, potential obstacles to be overcome in getting good answers to questions, and respondent problems that could be anticipated ahead of time, as well as strategies for addressing the potential problems. Due to the sensitive nature of some of the questions, interviewers were given specific instructions on how to cope with respondents who seemed agitated or distressed by the questions.
Interviewer training was conducted immediately before the survey was fielded. Call center supervisors and interviewers were walked through each question from the questionnaire. Interviewers were given instructions to help them maximize response rates and ensure accurate data collection.
Sampling Procedures
The sampling procedures were designed to efficiently reach the target populations of interest. These procedures are listed below:
1) SSRS pulled sample prescreened as Muslim households from the years 2012-2018 of its weekly national omnibus survey to recontact for this study.
2) SSRS pulled sample prescreened as Jewish households from the years 2016-2018 of its weekly national omnibus survey to recontact for this study.
3) SSRS purchased listed sample in both landline and cell phone frames. The landline sample was purchased from Experian and the cell phone sample was purchased from Consumer Cell. Experian and Consumer Cell are sample providers with specific characteristics flagged for each piece of sample. Experian and Consumer Cell provided sample with flags for Muslim and Jewish households.
4) In an effort to supplement the number of Muslim interviews that we were able to complete in the given time frame and with the amount of available prescreened sample, SSRS employed a Institute for Social Policy and Understanding, 2019 web panel and completed the final 383 Muslim interviews via an online survey with sample from a non-probability panel.
5) SSRS used their sample in the probability panel to administer the General Population portion of the survey. These are respondents who have completed a survey through the SSRS Omnibus and signed up for the probability panel.
6) In an effort to balance out the General Population probability panel SSRS interviewed 104 non-Internet respondents through the Omnibus, which uses a fully-replicated, stratified, single-stage, random-digit-dialing (RDD) sample of landline telephone households, and randomly generated cell phone numbers. Sample telephone numbers are computer-generated and loaded into on-line sample files accessed directly by the computer-assisted telephone interviewing (CATI) system.
