  1. 1. Do cell phone users differ by frame and should we care?<br />Presenter<br />Michel Boudreaux <br />AAPOR, Phoenix, Arizona<br />May 13, 2011<br />Funded by a grant from the Robert Wood Johnson Foundation<br />
  2. 2. Acknowledgments<br />Funding support:<br />MN Department of Human Services<br />MN Department of Health<br />Coauthors:<br />Kathleen Thiede Call<br />Donna McAlpine<br />Tim Beebe<br />Brett Fried<br />David Dutwin <br />2<br />
  3. 3. 3<br />National/Midwest Cell Phone Use<br />
  4. 4. To screen or not to screen<br />Lack of consensus in field on whether to: <br />Screen for cell phone only (CO) households<br />Include all but landline mostly<br />Interview the entire cell phone frame<br />Excluding some cell users could introduce error<br />Including all users complicates weighting due to overlapping probabilities of selection<br />4<br />
  5. 5. Research questions<br />Are cases omitted when screening for CO households different depending on which frame they are captured in (LL vs. Cell)?<br />Do these differences disappear when controlling for post-stratification variables?<br />5<br />
  6. 6. Data Sources<br />2009 MN Health Access Survey (MNHA) <br />Ongoing survey of health insurance/access<br />Accepted all cell phone completes <br />2010 MN Survey on Adult Substance Use<br />Focus on prevalence of drug/alcohol use and treatment patterns<br />Accepted only CO and CM cases <br />6<br />
  7. 7. Analysis<br />T-test/pairwise comparisons of: <br />Cell mostly sampled in LL versus Cell frame<br />Regression models with telephone usage as predictor, controlling for weighting variables <br />Full sample weights applied<br />7<br />
  8. 8. Unadjusted Demographics, MNHA <br />8<br />*<br />*<br />
  9. 9. Unadjusted Health Insurance, MNHA<br />9<br />*<br />*<br />
  10. 10. Adjusted Health Insurance, MNHA<br />10<br />
  11. 11. Unadjusted Demographics, MNSASU<br />11<br />*<br />
  12. 12. Unadjusted Health-Related Outcomes, MNSASU<br />12<br />*<br />
  13. 13. Adjusted Health-Related Outcomes, MNSASU<br />13<br />
  14. 14. Discussion<br />CM users from landline vs. cell frames do differ on health outcomes<br />However, post-stratification weighting appears to correct for these differences<br />This suggests that we can safely screen for CO<br />However, cost and variance remains an issue<br />14<br />
