  1. Impact of Reward Options Sheet in Mail One Survey Packet on Early Response among African American Women in OklahomaWanda Thomas, Alicia Lincoln, MSW,MSPH, Dick Lorenz, MSPHMaternal and Child Health ServiceOklahoma State Department of Health

  2. Phase 4 and Phase 5 Response Rates* Overall** and African American *Unweighted, gross response **African American response is included in overall response

  3. Phase 4 and Phase 5 Response Rates* Overall** and African American *Unweighted, gross response **African American response is included in overall response

  4. African American Response Trends Oklahoma PRAMS 2000-2007 Phase 4 2000-03, Phase 5 2004-08 Unweighted response rates

  5. Reward Options Sheet Oklahoma PRAMS Implemented 2006

  6. Alternate Reward Options Sheet For Mothers of Deceased Babies

  7. Increase early response Increase total mail response Increase final total response • Reduce burden of phone phase Test Objectives

  8. African American women in each of four batches evenly divided alphabetically Alphabetical division was rotated batch to batch 53 in test group (initially 57) 51 in control group (initially 56) Methodology

  9. Demographic Characteristics: Number of Women in Test Group and Control Group

  10. Birthweight Stratum: Number of Women in Test Group and Control Group

  11. Eliminated from analysis of early response: - Women with undelivered mail 1 packets • Eliminated from analysis of total response: - Women with undelivered mail and no good phone number Women Eliminated from Analysis

  12. Early and Total* Response Rates to Reward Options Sheet *Total response to date available for only one batch: n=15/test & 14/control

  13. Historic Overall Response Mode Compared to African American Test & Control Groups African American Overall

  14. Historic African American Mail ResponseCompared to Test & Control Groups African American African American

  15. Benefit of Early Response • Monetary Value • $1.65 - Music cd (including postage) • $2.32 - Chunky book (including postage) • $3.74 - mail two and three survey packets (combined) • Phone phase: interviewer salaries and phone charges • Surveillance Value • Early response may reduce recall bias • Participation by women who may be lost to followup • Improved response rates provide more valid data • Fewer moms in phone phase = more calls per mom

  16. Limitations •No guarantee that mail one survey packet was received •Small sample size (little statistical significance at p value of .17) •Unable to compare income levels as this information is not available when sample is drawn •Confounding variables may exist in either group of which we are unaware

  17. Inclusion of the reward options sheet is effective for increased early response Test with all women (one batch) resulted in: 25% early response among test group vs. 18% among control group (no women eliminated) Oklahoma now includes the rewards option sheet in the mail one survey packet for all women Conclusions

  18. All the women in Oklahoma who take the time to tell us about their experiences. Oklahoma PRAMS phone staff: Helen Couch, Rebekah Rodriguez, Catherine Diepenbrock-Leu CDC and the Oklahoma Title V Program for providing funding and support for OK PRAMS Oklahoma State Department of Health leadership for support of the Oklahoma PRAMS project Acknowledgements
