Chouhoud, Y., & Mogahed, D. (2020, March 27). ISPU American Muslim Poll, 2018.
Summary
Muslims and Jews were surveyed for the Institute for Social Policy and Understanding (ISPU) from Jan. 8, 2018 through Jan. 24, 2018. The study investigated the opinions of Muslims and Jews regarding the government, the most important issues facing the country, faith customs and religious, race, and/or 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 two low-incidence target populations of interest. These are listed below:
1) SSRS pulled sample prescreened as Muslim households from the last four years of its weekly national omnibus survey of 1,000 randomly selected respondents to recontact for this study.
2) SSRS pulled sample prescreened as Jewish households from the last two years of its weekly national omnibus survey to recontact for this study.
3) SSRS purchased listed sample in both landline and cell phone frames from Experian, a sample provider with specific characteristics flagged for each piece of sample. Experian provided sample with flags for Muslim households.
4) Finally, 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 web panel and completed the final 106 Muslim interviews via an online survey with a sample from a non-probability panel.
