The ISRC provides data collection through mail survey methods. This service includes instrument design, monitoring mail, incentive management, initial and follow-up mailings, tracking, reports and managing data.
The ISRC has University of Iowa students that have been certified through the UI Human Subjects Office’s CITI human subjects’ tutorial for IRB02 (and many cross-trained for IRB01) data collection. They have also received training in FERPA and HIPAA.
- Sample management (maintaining quotas, keeping appointments and more)
- Programming of skip patterns (uses the quantitative response to a question to determine the path of the interview and creates a smooth transition to the next relevant question in each situation)
- The randomization of questions or answer sets (can reduce the impact of ordering effect)
- Tracking (documents the result of the mail study and the date the survey was received at the ISRC)
