-- New guidelines for researchers conducting telephone
-- Recent studies show cell phones’ impact on sampling, data quality and costs --
Deerfield, IL -- The American Association for Public Opinion Research (AAPOR) announces an important update to its evaluation of the use of cell phones in survey research, and new guidelines for researchers conducting telephone interviews.
A steadily rising number of U.S. adults now have only a cell phone, requiring survey researchers to determine how to interview people on their mobile phones or risk unrepresentative results when studying the full population. Fully a quarter of U.S. households are now “cell only.”
To help the industry meet the difficult and costly challenges of cell phone surveys, AAPOR’s Cell Phone Task Force report, available at www.aapor.org, highlights important, new findings from the large number of studies conducted since the 2008 report was written.
The new cell phone surveying report offers essential background, including a description of how survey researchers select cell phone numbers, how excluding cell phones might affect results and how different types of cell phone and landline samples are adjusted to reflect the total population.
Although it remains too early to publish definitive standards or “best practices” for cell phone random digit dial (RDD) surveys, the report provides a clear set of questions any researcher should ask when conducting cell phone RDD surveying.
First, there is some good news: Despite initial fears, good cell phone samples are available for RDD research. Cell phone RDD samples consistently provide better coverage of the important demographic groups that often are underrepresented in landline-only RDD surveys, including men, younger adults and minorities.
However, there remain significant questions, including issues about coverage and sampling (e.g. “all cell” vs. “cell only” vs. “cell only and cell mostly”), non-response, potential bias and statistical weighting. There are also steep operational and cost issues, as well as legal and ethical considerations when interviewing people on cell phones.
A few key findings:
