Vaccine Acceptance in Pregnant Minority Women

6. marts 2015 opdateret af: Saad B. Omer, PhD, Emory University
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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: High Elaboration Video Arm
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.
Adfærdsmæssigt: Maternal Vaccine Education
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.
Eksperimentel: High Elaboration Interactive Tutorial Arm
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.
Adfærdsmæssigt: Maternal Vaccine Education
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.
Placebo komparator: Low Elaboration / Control Arm
Women randomized to the control arm will be provided standard CDC vaccine information statements that will likely lead to low elaboration information processing.
