This paper has a substantive focus on health care policy, but may have a better fit at AAPOR for its research design which compares results obtained from an 800 person RDD telephone sample with a 300 person cell phone sampling. Both of these are statewide samples in New Jersey, conducted by the same field house (SRBI) and over exactly the same time frame. As far as we know, this is one of the first studies to look at cell versus landline at the state level rather than the national level. The surveys were conducted by the Center for State Health Policy at Rutgers University, and funded by a grant from the Robert Wood Johnson Foundation. Our dependent variables include concern about various public issues, concern about various issues within the realm of health care, the role of government in this policy domain, health policy options and tradeoffs, personal health coverage and health status, and various demographics such as age, education, employment, race and marital status. Our primary independent variable is mode of data collection-land line vs. cell phone, although we hope to make a contribution in teasing out cell phone onlys (CPO) from cell phone mainlys (CPM). [We note that the majority of the U.S. population now has both cell phones and land lines, and that there are now more in the population with only cell phones than only land lines.] We explore different weighting schemes asking the question of what substantive (health) policy difference it makes should CPOs or CPMs have been excluded from the sampling frame.
