NCT01740310

Brief Summary

The purpose of study will be to test two vaccine education strategies to learn how they impact flu and pertussis (Tdap) vaccination rates and attitudes regarding vaccination during pregnancy after participating in the intervention. The education strategies will be based on the elaboration likelihood model (ELM). This model is based on experimental psychology and has been previously used to increase breast cancer screening rates. These education strategies will be delivered through routine prenatal care visits to black/African-American women in Atlanta.

Outcome Measures

Primary Outcomes (1)

  • Influenza vaccination rates in pregnancy

    Data on vaccination status will be collected from participants enrolled in the main phase of the study during follow up starting one month after the expected date of delivery. We will contact healthcare providers to obtain vaccination records for those who provide written consent to release their immunization records.

    Baseline and one month after participant's expected date of delivery

Secondary Outcomes (2)

  • Tdap vaccination rates in pregnancy

    Baseline and one month after participant's expected date of delivery

  • Change in attitudes regarding vaccination

    Baseline and one month after the expected date of delivery

Study Arms (3)

High Elaboration Video Arm

EXPERIMENTAL

Women randomized to this arm will be exposed to a handheld/electronic tablet device-based video with detailed vaccine-related information designed to invoke a high level of attention to the message and thought (elaboration) while processing information.

Behavioral: Maternal Vaccine Education

High Elaboration Interactive Tutorial Arm

EXPERIMENTAL

Women will be exposed to a handheld/electronic tablet device-based intervention designed to invoke a high level of attention to the message and thought (elaboration) while processing information through an interactive question/answer format.

Behavioral: Maternal Vaccine Education

Low Elaboration / Control Arm

PLACEBO COMPARATOR

Women randomized to the control arm will be provided standard CDC vaccine information statements that will likely lead to low elaboration information processing.

Behavioral: Maternal Vaccine Education

Interventions

It is assumed that the women will also receive vaccine education materials from the OB/GYN practices as part of routine care. The intervention for all three arms will be conducted during routine prenatal office visits. Participants will complete a baseline questionnaire to assess attitudes regarding vaccination and will then be randomized to one of three enrollment arms and will be exposed to an intervention designed to take no longer than 20 minutes, so that patients can complete it during the time they are waiting to be seen. While participants are completing the handheld/electronic tablet device-based intervention, the study recruiter will observe them and document dose exposure to the messages being presented. The enrolled women will be contacted a month after the expected date of delivery and a follow up interview will be conducted to ascertain their vaccination status for receipt of influenza vaccine in pregnancy and Tdap during pregnancy or immediately post-partum.
