RTI International case study presented at the FCSM Research and Policy Conference in March 2018. The survey instrument used in the RTI International case study below is based on a 27-question survey instrument that mimics questions from the National Health Interview Survey (NHIS) adult sample.
- Low cost—About one-tenth the cost compared to outbound telephone sampling.
- Quick—Can collect data on thousands of respondents a day.
- Low Burden—The respondent is already on the phone.
Good Fits for RICS Methodology
- Short survey instrument (up to 35 questions) and simple questions.
- Target geographies comprised of an area code or groups of area codes.
- Minimal Screening Criteria (extensive screening increases costs).
- Examples include Surveillance of population after a natural disaster (Hurricane Harvey) or a national or state surveillance of gastroenteritis (stomach flu).
- Develop the capacity to screen inbound callers with IVR and recruit to a web-instrument
- Evaluate the stability of the estimates in repeated cross-sectional studies.
- Evaluate the best use of the IVR system; Enter data with keypad, conversational IVR, or both.
- Evaluate bias in RICS surveys that use redirected toll, verses toll-free numbers.
- Develop and evaluate different weighting approaches—Orthogonal to the demographic distributions used calibration correlated to the study outcomes.
