Project Overview +

Vax Facts offers a tailored brochure to address parents' concerns about HPV vaccines. The intervention draws on our previous data on reasons parents decline HPV vaccines for their daughters. This data is used to develop questions and responses that elicit and address parental beliefs that hinder HPV vaccine series initiation. Intervention messages are tailored to address these beliefs and concerns.

Aims +

Aim 1. To develop an educational intervention that provides information tailored to address the specific, individual-level concerns of parents about HPV vaccines. A series of questions and responses designed to elicit and address parental beliefs that hinder HPV vaccine series initiation is used to generate a 2-page, individually-tailored, educational brochure for each parent in the study.

Aim 2. To test whether this intervention increases parents' intention to allow their daughter to be vaccinated with HPV. Changes in parental HPV vaccination intention before and after viewing the intervention is the primary outcome assessed in the study. Additionally, electronic medical records at the UM are used to determine HPV vaccination status among daughters of parents in the study 3 months after the intervention.

Participants +

Parents of 11-17 year old females who have not received any doses of the HPV vaccine, who receive primary care at one of the outpatient UM general pediatric clinics, and who are hesitant for the HPV vaccine.

Intervention +

Participants complete a baseline survey on the study laptop. The survey data is then used to produce a printed, tailored brochure for the participant to review. The brochure is tailored to address the participant's top 3 barriers to HPV vaccination. Parental HPV vaccine intention is measured before and after viewing the brochure using a 2-item scale.

Findings +

Mothers who received the tailored educational brochure had statistically higher intentions to vaccinate their adolescent daughter against HPV within the coming year when compared to the control group that received the untailored brochure.

Initial findings of vaccination: Assessment of actual vaccine receipt 3-months after the intervention was delivered showed no differences between groups in the rate of vaccine administration (5% of the daughters were vaccinated in both the control and intervention groups).
