About this study

Official title: Vax Facts HPV: Study of a Computer-based Tailoring System and Mothers' Intentions to Vaccinate Their Daughters Against HPV

The goal of this study is to determine whether a two-page print brochure that delivers individually tailored educational messages about the Human papillomavirus (HPV) vaccine increases HPV vaccine-hesitant mothers' intentions to have their adolescent daughters vaccinated against HPV.

Read the detailed description

This will be a randomized controlled intervention trial for HPV vaccine-hesitant mothers of adolescent (ages 11-15 years old) girls. Mothers will complete a three-item measure that assesses their baseline intentions for having their adolescent daughter vaccinated against HPV. Mothers will then fill out a short, computer-based survey that assesses demographic factors, prior experience with HPV-associated illnesses and views about a variety of potential barriers to HPV vaccination. Following the survey, the intervention group (40 mothers) will receive a two-page print brochure that uses their survey data to generate the brochure such that it addresses each mother's top three concerns about the HPV vaccine. The control group (40 mothers) will receive a generic, two-page brochure that is similar in appearance to the intervention, but contains only untailored, generic information about the vaccine. HPV vaccination intention will be assessed a second time after reading the brochure, using the same three-item measure as before the survey. The vaccine administration records of the adolescent daughters of these mothers will be accessed three months after mothers' participation in the study to assess whether any HPV vaccine doses were provided.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Computer-based tailoring systemBehavioural

    Both the intervention and control groups will use a computer-based tailoring system to respond to survey questions. The computer-based tailoring system will produce messages for a two-page educational brochure based on participants' responses to survey questions. Only the intervention group will receive this brochure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mother's Intention to Vaccinate Daughter Against HPV

    Mother will rate her intention to have her daughter vaccinated against HPV using a Likert scale before and after the intervention. The scale ranges from 0-11 with higher numbers representing more positive intentions to vaccinate against HPV, and 5 being neutral intentions (i.e. neither positive nor negative). In this assessment we use this 11-point scale to assess vaccination before and after viewing the educational materials. The difference pre and post intervention in vaccination intention is calculated (min 0, max 11) and the mean of these differences are calculated for the control and intervention groups.

    Measured: Date of intervention (one day)

Secondary outcomes (1)

  1. Vaccination of Daughter

    With mother's consent, daughter's University of Michigan vaccination record will be accessed to determine whether daughter has received any doses of the HPV vaccine. If the University of Michigan vaccination record does not document a visit three months after the intervention, with mother's consent, research staff will call mother at home to determine whether daughter has received any doses of the HPV vaccine.

    Measured: Less than or equal to three months from the date of the intervention
